TECHNICAL FIELD

The present disclosure relates generally to movement of industrial devices in an industrial environment. More particularly, it relates to methods, network node, and computer program products for optimizing a planned movement of industrial devices in the industrial environment.

BACKGROUND

Industrial automation is becoming increasingly popular due to rapid development in sensors, control system, and other manufacturing techniques. In industrial automation, various kinds of industrial devices (such as 6DOF robotic arms, collaborating robotic arms, Automated Guided Vehicles, AGVs, with omni-wheels, or other robotic devices) are used to automate various process in industries. For example, the industrial environment includes one or more industrial devices that receive a movement path from an industrial controller and the one or more industrial devices follow the received movement path accordingly.

The current industrial applications use wired connection between the industrial devices and the industrial controller. In wired networks, high-quality connectivity is available. Therefore, wired connection can always provide very low propagation delay and no packet loss.

Increased popularity of industrial automation leads to focus on developments where wireless connections are used between the industrial devices and the industrial controller. The wireless connection generally introduce more propagation delay and packet loss. For example, the wireless connections introduce additional non-ideality as compared to the wired connection. This non-ideality, e.g. increased jitter in command messages, can cause higher deviation from the desired movement path of the industrial devices and hence it reduces the accuracy of the trajectory execution of the industrial devices. A partial loss of packets or delayed reception of packets at the industrial devices can result in performance degradation or deviation from the desired movement path. The use of the appropriate radio connection for industrial applications is crucial for radio resource usage efficiency and industrial task execution accuracy. SUMMARY

FIG. 1 discloses an industrial environment 100. Some of the examples of the industry environment 100 may include a factory, a manufacturing unit, guided robotic environment, etc. The industrial environment 100 comprises an industrial controller 102, a network node 104 and industrial devices 108a, 108b, 108c and so on to 108n. The network node 102 communicates with one or more industrial devices 108a - 108n through a wireless communication network 106 for controlling the movement of one or more industrial devices 108a - 108n. For example, the one or more industrial devices 108a - 108n is configured to receive command messages and/or data packets from the network node 104 through the wireless communication network 106. For example, the network node 104 may be a radio access network comprising a plurality of base stations or evolved node base stations (not shown) or the internet using one or more suitable communication protocols for transmitting the data packets to the one or more industrial devices 108a - 108n. The industrial controller 102 is configured to generate a movement path. Examples of the industrial devices 108a - 108n may comprise Articulated Robots, Cartesian Robots, Selective Compliance Assembly Robot Arm, Delta robots, Polar robots, a 6-DOF robotic arm, collaborating robotic arms, Automated Guided Vehicles, AGVs, with omni-wheels, or other robotic devices.

The network node 104 is configured to acquire at least one movement path for industrial devices 108a - 108n from the industrial controller 102. The movement path may be generated by an industrial application being executed in the industrial controller 102. Further, the network node 104 transmits the at least one movement path to the industrial devices 108a - 108n through the wireless communication network 106. The industrial devices 108a - 108n is configured to receive the at least one movement path from the network node 104. A trajectory may comprise the movement path to be followed by the industrial devices 108a - 108n. For example, the industrial devices 108a - 108n comprise one or more actuators (e.g. servos, arms, wheels, or the like) that move according to the movement path. In an ideal system, the execution of the movement path results in exact movement path. It should be noted that the industrial environment 100 is not limited to above-mentioned components, other components can also be present in the industrial environment 100 other than the component shown in the FIG. 1.

The wireless communication network 106 is used for transmission of the movement path to the industrial devices 108a - 108n. The wireless connection generally introduces more propagation delay and packet loss. For example, the wireless connections introduce additional non-ideality as compared to the wired connection. This non-ideality, e.g. increased jitter in command messages, can cause higher deviation from the desired movement path of the industrial devices 108a - 108n and hence it reduces the accuracy of the trajectory execution of the industrial devices 108a - 108n. A partial loss of packets or delayed reception of packets at the industrial devices 108a -108n can result in performance degradation or deviation from the desired movement path. The use of the appropriate radio connection for industrial applications is crucial for radio resource usage efficiency and industrial task execution accuracy.

Therefore, according to some embodiments of the present disclosure, the network node 104 implements a method for optimizing a planned movement of one or more industrial devices 108a - 108n, in the industrial environment 100. According to some embodiments of the present disclosure, the network node 104 acquires at least one movement path forthe one or more industrial devices 108a - 108n. Each movement path comprises one or more segments indicative of movement data. For example, a trajectory includes one or more movement paths to be followed by the industrial devices 108a - 108n.

Further, the network node 104 determines a Quality of Service, QoS requirement for each segment. The network node 104 determines for each segment whether the determined QoS requirement fulfills an estimated QoS maintained by the network node 104. For example, the network node 104 acquires a network coverage map maintained by the network node 104. The network coverage map indicates a network condition within a coverage area of the industrial environment 100. Further, the network node 104 obtains the estimated QoS using the network coverage map.

Further, when it has been determined that the QoS requirement for each segment fulfills the estimated QoS, the network node 104 transmits the movement path to the one or more industrial devices 108a - 108n. For example, the network node 104 compares the QoS requirement for each segment and the position information with the estimated QoS and determines whether the network node 104 is able to maintain the QoS requirement for each segment. When it has been determined that the network node 104 is able to maintain the QoS requirement for each segment, the network node 104 configures at least one QoS parameter between the network node 104 and the one or more industrial devices 108a - 108n. When it has been determined that the network node 104 is not able to maintain the QoS requirement for each segment, the network node 104 transmits a message to an industrial application for regenerating the movement path.

The network node 104 transmits the at least one movement path to the one or more industrial devices 108a - 108n when it has been determined that the QoS requirement for each segment fulfills the estimated QoS. Further, the network node 104 discards the at least one movement path and transmits a message to the industrial device for regeneration of the movement path when it has been determined that the QoS requirement for each segment does not fulfill the estimated QoS. Thus, the performance degradation or deviation from the desired path of the industrial devices 108a - 108n may be mitigated. Thereby, the embodiments herein provides optimization of the planned movement of the industrial devices 108a -108n in the industrial environment 100. Figure 2 is a flowchart illustrating example method steps of a method 200 performed by the network node in the wireless communication network for optimizing a planned movement of one or more industrial devices in the industrial environment.

At step 202, the method 200 comprises acquiring at least one movement path for the one or more industrial devices, each movement path comprising one or more segments indicative of movement data. The network node receives the at least one movement path from the industrial controller. For example, a trajectory includes one or more movement paths to be followed by the industrial devices for performing an assigned task or a sub-task of the assigned task. The trajectory of an industrial device typically includes the desired velocity information for each servo. For example, the trajectory for a 6 DOF robotic arm which has six servos can be defined as:

Trajectory =

Servo-1: {t=0 [sec], v=0 [rad/sec]}, {t=0.01 [sec], v=0.03 [rad/sec]},..., {t=19.99 [sec], v=0.02 [rad/sec]}, {t=20 [sec], v=0.0 [rad/sec]}};

Servo-2: {t=0 [sec], v=0 [rad/sec]}, {t=0.01 [sec], v=0.02 [rad/sec]},..., {t=19.99 [sec], v=0.04 [rad/sec]}, {t=20 [sec], v=0.0 [rad/sec]}}

Servo-6: {t=0 [sec], v=0 [rad/sec]}, {t=0.01 [sec], v=0.01 [rad/sec]},..., {t=19.99 [sec], v=0.04 [rad/sec]}, {t=20 [sec], v=0.0 [rad/sec]}}]

The trajectory instructs the industrial device on how to move for an assigned time interval. The industrial device composed of one or more actuators (e.g. servos, wheels, arms, or the like) for performing the assigned task. The movement path includes a desired velocity function for each actuator of the industrial device. Additionally, the movement path comprises joint positions and acceleration values. The movement path can be specified by splines. The movement path may be segmented into one or more segments. Each segment comprises movement data which includes a value for a desired velocity at a given time interval. For example, if the trajectory comprises the movement path for 20 seconds, the movement path may be divided into 100 small segments. Thus, each segment describes a desired velocity for a time interval of 0.2 seconds. At step 204, the method 200 comprises determining the QoS requirement for each segment. The network node analyses each segment of the movement path. Based on the analysis, the network node determines the QoS requirement for each segment. The QoS requirement indicates the quality of coverage of the wireless network within the industrial environment based on the position and/or movement of the industrial devices within the industrial environment.

Examples of the QoS requirement may include Static-QoS and Dynamic QoS. In the Static- QoS, the whole movement path has a single QoS requirement. The strictest QoS requirement considered and that should be available along the complete movement path. In the Dynamic QoS, each segment of the movement path has its own QoS requirement and radio connection is reconfigured dynamically.

In some embodiments, the industrial controller recalculates the movement path to avoid challenging radio zones or decreases the speed of the movement of the industrial devices. The network node identifies the weak points of radio coverage and provides them to the industrial controller for re-planning of the movement path.

In other embodiments. The network node obtains the one or more segments of the movement path. For example, the network node may segment the movement path into one or more segments. Further, the network node obtains one or more segment types comprising at least one pre-determined parameter indicative of a state of movement of each industrial device along the movement path. The examples of the state of movement of the industrial device may include Steady-state, Accelerating state, Decelerating state, Travelling state, Curving state, Slaloming state, Approaching state, Synchronized movement or the like. The examples of the at least one parameter comprises one or more of a movement-phase label indicating a current state of each industrial device along the movement path, an intensity value indicating a velocity of each industrial device along the movement path or the like.

The network node identifies a segment type corresponding to each segment by analyzing each segment of the movement path. For example, the network node extracts each segment of the movement path and determines a state of the industrial device. Further, the network node compares the state of the industrial device with the at least one pre-determined parameter to identify the segment type. The network node assigns the at least one pre- determined parameter of each segment based on the segment type of each segment. The network node further contracts the adjacent segments with same label. Further, the network node contracts the adjacent segments (e.g. Curving/Accelerating/Decelerating/Travelling segments) to a single segment (e.g. a Slaloming segment). The network node assigns an intensity value to each segment of the movement path. The movement-phase label indicates a state of movement of each industrial device along the movement path. The network node determines the intensity value based on the state of each industrial device. For example, the intensity parameter for steady state is determined as zero. The network node assigns the movement-phase label and the intensity value by using a pre- determined table as shown in table 1.

Table 1.

The network node further maps the at least one pre-determined parameter of each segment with pre-determined QoS parameters of the network node. For example, the network node obtains the pre-determined QoS parameters of the network node and compares the obtained pre-determined QoS parameters with the assigned movement-phase label and the intensity parameter of each segment of the movement data. The mapping functionality can be rulebased method, supervised learning method (if labeled training data is available, e.g., from simulation or measurement) or simply determined by using expert knowledge. Further, the network node determines the QoS requirement for each segment based on the mapping. For example, the network node extracts a configured QoS requirements from the pre-determined QoS parameters based on the assigned movement-phase label and the intensity parameter of each segment.

At step 206, the method 200 comprises determining for each segment whether the determined QoS requirement fulfills an estimated QoS maintained by the network node. The network node determines the estimated QoS using a network coverage map maintained by the network node. Further, the network node determines whether the QoS requirement for each segment fulfills the estimated QoS maintained by the network node. The step of determining for each segment whether the determined QoS requirement fulfills an estimated QoS maintained by the wireless communication network is explained in conjunction with FIG.

3.

At step 208, the method 200 comprises transmitting the at least one movement path to the one or more industrial devices when it has been determined that the QoS requirement for each segment fulfills the estimated QoS. The network node configures at least one QoS parameter to maintain the QoS requirement for each segment when it has been determined that the QoS requirement for each segment fulfills the estimated QoS. For example, the network node updates the QoS parameters of radio resources such that the QoS requirement of each segment fulfils the estimated QoS.

Furthermore, when it has been determined that the QoS requirement for at least one of the segments does not fulfill the estimated QoS, the network node transmits a message to an industrial application for regenerating the movement path as depicted in optional step 210. The message comprises one or more of the at least one of the segments, position information about the at least one of the segments, and maximum estimated QoS supported by the network node. For example, the network node determines the segments for which the QoS requirement does not fulfills the estimated QoS and extracts the maximum estimated QoS supported by the network node. Further, the network node generates the message comprising one or more of the at least one of the segments, position information about the at least one of the segments, and maximum estimated QoS supported by the network node.

Thus, the network node considers the available radio network condition within the industrial environment before transmitting the movement path to the industrial devices. Thus, the performance degradation or deviation from the desired path of the industrial devices may be mitigated. Thereby, the embodiments herein provides optimization of the planned movement of the industrial devices 108a -108n in the industrial environment 100.

Figure 3 is a flowchart illustrating example method steps of a method 300 performed by the network node in the wireless communication network for determining for each segment whether the determined QoS requirement fulfills an estimated QoS maintained by the wireless communication network.

At step 302, the method 300 comprises acquiring a network coverage map maintained by the network node. The network coverage map indicates network conditions within the industrial environment. For example, the network node acquires the network coverage map indicating a network condition within a coverage area of the industrial environment. The network coverage map comprises details of the signal condition at each location within the coverage area of the industrial environment. The signal condition varies within the coverage area depending upon the location of the industrial devices.

At step 304, the method comprises obtaining the estimated QoS from the network coverage map. The network node analyses the network coverage map and obtains the estimated QoS maintained by the network node. For example, the network node estimates the service quality of the network node of the coverage area of the industrial environment. Further, the network node obtains the estimated QoS according to the service quality of the network node within the coverage area.

At step 306, the method 300 comprises acquiring position information of the one or more industrial devices. The network node acquires the position information of each industrial device. The position information indicates a starting point and a target point of movement path. The position information of the starting point and the target point is described by coordinates of the locations. The movement path further includes one or more routes between the starting point and the target point.

At step 308, the method 300 comprises comparing the QoS requirement for each segment and the position information with the estimated QoS. The network node considers the QoS requirement for each segment along with the position information and compares with the estimated QoS. For example, the network node determines the radio network conditions by using the network coverage map and compares the radio network conditions with the QoS requirement for each segment and the position information.

At step 310, the method 300 comprises determining whether the network node is able to maintain the QoS requirement each segment by comparing the QoS requirement with the estimated QoS. The network node evaluates the QoS requirement and determines whether the network node is able to maintain the QoS requirement for each segment of the movement path. The network node determines whether the requested QoS can be guaranteed for the movement path by comparing the QoS requirement for each segment with the position information with the estimated QoS. For example, the network node checks a spatial and a temporal availability of desired connectivity by using the QoS requirement extended with the position information. The spatial and temporal availability indicates whether the QoS requirement can be fulfilled by the available radio resources of the network node. The QoS requirement extended with the position information may provide relatively more accuracy.

Upon the determination that the network node is able to maintain the QoS requirement for each segment, the network node configures at least one QoS parameter to maintain the QoS requirement for each segment. Further, upon the determination that the network node is not able to maintain the QoS requirement for at least one of the segments, the network node transmits a message to an industrial application for regenerating the movement path. For example, the network node generates the message that instructs the industrial application to redesign the movement path for controlling the movement of the industrial devices. The message comprises information required for redesigning the movement path. The information required for redesigning the movement path may comprise at least one segment for which the network node is not able to maintain the QoS requirement, the position of the at least one segment and the maximum estimated QoS supported by the network node. The industrial application receives the message and regenerates the movement path according to the message. The industrial application may consider the information in the message in regeneration of the movement path such that the regenerated movement path can be transmitted to the industrial devices in accordance with the QoS requirement. As an example, acceleration, deceleration and nonlinear motion segments require high QoS in radio connection. If that is not available, for instance, due to bad radio coverage, then the industrial application receives a feedback and regenerates the movement path such as decreasing the speed of the movement of the industrial devices, avoiding the segments that requires the industrial devices to move into challenging radio zones, avoiding acceleration, deceleration and nonlinear travelling motion segments when travelling through challenging radio zones. Thus, the network node is able to maintain the QoS requirement of the movement path. The method can be used in an iterative design method where the movement path and the radio network are jointly optimized.

Figure 4 is an example schematic diagram showing apparatuses 102 and 104. The apparatus

102 may e.g. be comprised in the industrial controller. The apparatus 104 may e.g. be comprised in a network node. The apparatus 102 is capable of generating the movement plan on the basis of the input received from the user. The apparatus 104 is configured to cause performance of the method 200 for optimizing a planned movement of one or more industrial devices, in an industrial environment.

According to at least some embodiments of the present invention, the apparatus 102 in FIG. 4 comprises one or more modules. These modules may e.g. be an industrial application 402, a movement path planner 404, and a movement path executer 406.

As described above, the various ways of transmitting the data packets to UE to deliver the control message to each of the plurality of industrial devices, a few of which have been mentioned above in connection to the explanation of FIG. 2.

The industrial application 402 is configured to execute an application for controlling the industrial devices 108a - 108n. The application may be any kind of application that generates commands to be followed by the industrial devices 108a - 108n. The industrial application 402 further control the movement path planner 404 to generate at least one movement path for controlling the movement of the industrial devices 108a - 108n.

The movement path planner 404 is configured to obtain input from the industrial devices 108a - 108n and generate the at least one movement plan based on the received input. The movement planner 404 is further capable of regenerating the movement plan based on the message received from the network node 104. For example, the movement planner 404 receive the message from the network node 104 when it is determined that the network node is not able to maintain the QoS requirement.

The movement path executer 406 receives that movement path from the movement path planner 404. Further, the movement path executer 406 executes the movement plan for each industrial device 108a - 108n. For example, the movement path executer 406 extracts the movement plan for each industrial device 108a - 108n and implements the movement path to each industrial device 108a - 108n.

According to at least some embodiments of the present invention, the apparatus 104 in FIG. 4 comprises one or more modules. These modules may e.g. be parameter assignor 408, an evaluator 410, an updater 412, and a controlling circuitry 414. The parameter assigner 408 is configured to receive the movement path from the movement path planner 404. The parameter assigner 408 further assigns the at least one parameter to each segment of the movement plan. The at least one parameter is assigned to each segment according to table 1.

The evaluator 410 obtains the assigned segments from the parameter assigner 408. Further, the evaluator 410 acquires the network coverage map maintained by the network node. The evaluator 410 evaluates the QoS requirement for each segment with regard to fulfilling a desired QoS, determined using the network coverage map maintained by the network node. For example, the evaluator410 determines whether the network node 104 is able to maintain the QoS requirement for the movement path by comparing the QoS requirement with the network coverage map. Further, the evaluator is configured to transmit the message to the industrial controller 102 when it is determined that that the wireless communication network is not able to maintain the QoS requirement of the movement path.

The updater 412 is configured to configure at least one QoS parameter to maintain the QoS requirement for each segment when it is determined that the network node is able to maintain the QoS requirement of the movement path.

The controlling circuitry 414 may be adapted to control the steps as executed by the network node 104. For example, the controlling circuitry 414 may be adapted to control the one or more modules comprised in network node 104 (as described above in conjunction with the method 200 and FIG. 2).

Further, the network node 104 is configured to transmit the movement path to the industrial devices 108a - 108n in accordance with the QoS requirement for each segment. Thus, the performance degradation or deviation from the desired path of the industrial devices 108a - 108n may be mitigated. Thereby, the embodiments herein provides optimization of the planned movement of the industrial devices 108a -108n in the industrial environment 100.

Further, any logical and arithmetic operations involved in the execution of the instructions are computed with the help of the ALU 506.

The computer program is loadable into the processing unit 502, which may, for example, be comprised in an electronic apparatus (such as a UE or a network node). When loaded into the processing unit 502, the computer program may be stored in the memory 512 associated with or comprised in the processing unit 502.
