Kind Code:
A1
Abstract:
According to the present invention, provided is a workplace safety management system comprising: a plurality of node units (100) installed in a workplace area (1); a local server (200) that is mobile and connected to a management server (10) via wireless communication; and a tag (300) attached to a worker, wherein the node unit (100) and the local server (200) are connected through a network system (400), wherein the network system (400) comprises: a long-range network (410) for connecting the node unit (100) to the local server (200); and a mesh network (420) for connecting the plurality of node units (100) to each other, and wherein the mesh network (420) connects the node unit (100) to the local server (200). According to the present invention, a workplace safety management system capable of being constructed at low cost and reused can be configured, and in addition, according to the present invention, battery utilization efficiency of a node unit installed in a workplace is increased and a sensing blind spot is minimized by mixed use of various networks, such as a long-range network (LoRa), a proximity network (WiFi, Bluetooth), and the like, and information about workplace safety management is transmitted to a management server and a local server by using various communication networks, and thus information can be smoothly transmitted even under problematic situations, such as a packet loss or the like caused by disconnection of some communication networks or overload of communication information, thereby providing an effect of increasing stability of workplace safety management.
