Technical Field

[0001] The technical field of this invention relates to analog control and management equipment for building interior energy consumption.

Background Art

[0002] The invention titled as Method for synchronizing the analog display means and a volatile time counter in a timepiece, published under registration number 05106032, discloses that:

[0003] The method involves calculating and storing a value (Vtps) representative of time information in a time counter. The value is updated based on a function of a supply frequency of the information, and is displayed using an analog display unit in a time mode. A value non-representative of the information is displayed in a non-time mode. The end of lifetime of the power supply is detected and the unit is set in a preset reference position. The value of the counter is set to a preset reference value and the unit is synchronized with the value of the counter during the replacement of the supply. An independent claim is also included for a multifunction electronic watch.

[0004] The method and objective of this invention are different from that of the claimed invention. Technical Problem

[0005] All buildings are equipped with electricity, water, and gas meters. However, many of them are obsolete and mechanical type and replacing the meters can be very time-consuming and is not cost-effective. Even subsequently, replacing these meters with smart ones will cause bigger issues in the production and installation stage.

[0006] Reading conventional meters requires personnel to read each of these meters periodically. This has challenges including the absence of the owner while reading the meter or the impossibility of timely reading and even unreadability of meter numbers and accessibility issues and so on. [0007] The dimension and form of the existing meters are not standard an meter has a specific display model, and such inconsistencies make it impossible to use smart sensors extensively, and governments will sometimes think of changing the mechanical meter to a digital one, which in turn is not cost-effective.

[0008] Mechanical meters have major issues, including the possibility to manipulate the meter, and this is a major drawback and limitation. Wrong meter reading by the meter reader is another common and problematic mistake in issuing bills.

[0009] Also, the current sensors, which are mainly produced by different companies, face some challenges after installation, which is the main reason behind the unpopularity of existing meters. Also, the need to implement infrastructure for the final operation or bulk size of the sensor and difficulties in installation and operation are other drawbacks.

Solution to Problem

[0010] In this invention, smart control and management of water, gas, and electricity meters are performed in a single unit. This can improve the quality of smart control and management and on the other hand reduce installation and maintenance costs. This device also has the potential to control multiple meters simultaneously and can store data to send them to the company if necessary.

[0011] The parts and components utilized in this device are a set of modules, CPUs, and sensors that are properly arranged together to be able to obviate the defects of present various meters from the production to installation and servicing stage.

[0012] On the other hand, this device can be connected and integrated to water, electricity, and gas distribution networks and utilities to apply any management and control over user consumption. In case the distribution network aims to monitor the consumption of each energy or decide to break off it, this system can provide this possibility in absence of the person in charge.

[0013] At the same time, it is also possible to issue an electronic notice to the subscriber. In this system, the infrared and serial protocol is used to send and receive all consumption information and manual system setup. But the most important part of this device that makes it affordable and usable for everyone, is the infrared sensor that allows receiving information from analog counter.

Description of Embodiments

[0031 ] Figure 1 illustrates the installation method of the device on the meter, where the device is arranged so that sensor (1 ) can be seen easily. As it can be seen, the sensor is tilted to one side of the device. The body of the device (2) is designed as a circle, part of which is empty. The perimeter of the device body has a circular frame (3). All parts of the device are located inside this f is possible to rotate the body of the device inside the frame.

[0032] To start the sensor, the user must place the device, which is connected to the meter body by a hinge (4), on the meter so that the sensor is in front of the desired hand. Since the body of the device can be rotated inside the frame, the user can rotate the body inside the frame (5) to place the sensor on each of the hands to read the related information.

[0033] Figure 3 indicates the infrared sensors installed on the main board (6). This device has an infrared transmitter (7) which is located in the middle of a conical cylindrical frame (8). There are ten infrared receivers (9) inside the conical cylindrical frame around the infrared transmitter. All infrared receiver holes are curved toward the center of the cylinder and above it so that the sensors function properly.

[0034] Information processing:

[0035] The device information processing part includes the following:

[0036] 101 - Controller valve

[0037] 102 - CPU

[0038] 103 - Barometer Sensor

[0039] 104 - Scanner Sensor

[0040] 105 - Magnet Sensor

[0041 ] 106 - Temperature Sensor

[0042] 107 - Serial Port

[0043] 108 - LCD

[0044] 109 - Keyboard

[0046] 1 1 1 - RF

[0047] 1 12 - RF

[0048] 1 13 - LORA [0049] 114 - Antenna

[0050] 115 - Antenna

[0051] 116 - Antenna

[0052] The device consists of several sensors, microcontrollers, and radio modules arranged together and each performs its function in achieving the ultimate goal.

[0053] The main microcontroller is responsible for receiving the information of the sensors from the entry and counts and calculates the summation of the variable numbers from the meter. It is also responsible for processing temperature and pressure and understanding various warnings from entries.

[0054] This microcontroller could encode information and send it to a nearby hub by creating a radio wavelength and placing it on a special free-bandwidth transmitter. It also has an output control base for breaking off/on the solenoid valve, which can be connected electronically or mechanically relay.

[0055] The magnet sensor is designed for two purposes. First, receive a magnetic pulse from the meter hand and send it to the microcontroller. Second, detect the possibility of an external magnet near the device and the meter and send the notification to the microcontroller as a manipulation error.

[0056] The thermometer sensor can receive the temperature of the water pipe and send it as a code to the microcontroller and can be informed of the water temperature of each meter in the server software. The pressure sensor does not fit in this package and is designed as an optional and can receive input or output pressure from the water meter and send it to the server.

[0057] The radio module receives the information from the microcontroller and does not do any processing and sends it directly on the frequency 433 or the desired frequency and can also receive information.

[0058] In Figure 4, a microcontroller is embedded as the central core and serves more as memory and device management, and its functions are:

[0059] • Sending and receiving static IPs to sensors to identify each as a different subscription

[0060] • making connection between server and sensors [0061] • To make connect to serial port and meters with RS 485 output

[0062] • Generation of radio signals with encrypted codes

[0063] A matrix keyboard is required to adjust the number and type of sensors to the central hub, or central microcontroller. A small LCD is also installed to display the device's setting conditions and to display various alarms. A small serial port is installed that can be used for programming and connection with digital meters. This port is two-way and can send and receive data.

[0064] A 433 frequency short-range radio module is installed that can communicate with the sensors, and this connection can be made two-way. There is also a long- range radio module with a frequency 433, which also can change the frequency, and this module is for connection with the server over long distances.

[0065] The service life of the whole set with a 3 amp battery ranges from 5 to 11 years, and this time depends on the type of sending and receiving, which can be changed through the server software.

[0066] Implementation method:

[0067] This device can have one or more sets of sensors to read the types of meter hands simultaneously or it can have only one set of sensors that are mounted on top of each meter to receive information.
