Problems solved by technology

[0002] In factories and mines and other places that need to monitor the location of personnel and equipment, most systems currently use wired or WiFi systems to track the location information of personnel and equipment in the working factory area. Such systems are complex to install and poor in mobility.
The point-to-point transmission distance of the WiFi system is short, and the self-organizing network cannot be realized, which greatly limits the application of this type of system and still needs technical improvement

Abstract

A hazardous area personnel positioning device with a wireless sensor network is characterized by comprising a plurality of router nodes, a plurality of personnel detecting nodes, a coordinator and an upper computer. Each router node is composed of a first master controller, a temperature detecting module connected with the first master controller and a zigbee wireless communication module. Each personnel detecting node is composed of a second master controller, a sound-light alarm module connected with the second master controller, a display module and a zigbee wireless communication module. The coordinator is composed of a third master controller and a GPRS module connected with the third master controller. The router nodes and the personnel detecting nodes, the router nodes, and the router nodes and the coordinator are connected through the zigbee wireless communication modules respectively, and the coordinator is connected with the upper computer through the GPRS module. The hazardous area personnel positioning device can achieve real-time detection of environmental parameters, can carry out personnel positioning, and meanwhile uses the GPRS for uploading data to the upper computer, so that production and management of a hazardous work place are more intelligent and user-friendly.

Description

technical field [0001] The invention relates to a personnel positioning device for factories and mines, in particular to a wireless sensor network personnel positioning device for dangerous places. Background technique [0002] In places such as factories and mines that need to monitor the location of personnel and equipment, most systems currently use wired or WiFi systems to track the location information of personnel and equipment in the working factory area. Such systems are complex to install and poor in mobility. The point-to-point transmission distance of the WiFi system is short, and the self-organizing network cannot be realized, which greatly limits the application of this type of system, and still needs technical improvement. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a device for locating people in dangerous places through a wireless sensor network. [0004] The technical solution adopted i...
