Positioning method and positioning device for power plant personnel

Abstract

The present invention provides a positioning method and a positioning device for power plant personnel, which are applied to a power plant monitoring system. The positioning method includes: acquiring a ZigBee signal sent from a mobile device, wherein the ZigBee signal includes the sending time of the ZigBee signal and The identification information of the mobile device, the mobile device is worn by the personnel of the power plant; obtaining the reception time when each positioning device of at least three positioning devices installed in different positions of the power plant receives the ZigBee signal; based on each The fixed coordinates of the positioning device, the sending time of the ZigBee signal and the receiving time of the ZigBee signal are used to obtain the current spatial position of the mobile device; based on the spatial position, the information corresponding to the spatial position is called a floor map, and display the identification information and its corresponding spatial position on the floor map in real time.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for locating personnel in a power plant and a device for locating personnel in a power plant. Background technique [0002] Electric power production safety is the unity of safety and production, safety promotes production, and production must be safe. Especially in power production environments such as thermal power plants and thermal power plants, a large number of large-scale live or magnetic equipment and many small power equipment are installed. In the links of maintenance and technical transformation, the location of personnel is monitored in time, the time of arrival of personnel is controlled, and when an accident occurs, it can be located and quickly arrived at the scene, so as to effectively prevent and deal with casualties, so that the technical means of safety production management of power generation enterprises can be handled passively. become active monitoring. ...

AI Technical Summary

Problems solved by technology

At present, in the monitoring system of the power plant, there is no mature and complete personnel positioning system applied to the power plant. The main reason is that the construction is difficult, the cost is high, and the effect is low.

[0003] With the rapid development of smart devices, the continuous reduction of hardware costs and the continuous maturity of network technology, a variety of wireless communication methods have emerged, such as communication technology based on ZigBee technology. Due to its low power consumption, low radiation, low cost, and combination The characteristics of network flexibility overcome similar positioning technologies (WIFI, Bluetooth, UWB, RFID, GPS, Beidou, etc.) with high networking requirements, high power consumption, slow response, poor reliability, high cost, or weak anti-electromagnetic interference capabilities, etc. Due to various defects, it has been widely used, but ZigBee technology has not yet been applied in the special scene of the power plant, and in the current working process of the staff of the power plant, the requirements for safety are getting higher and higher, so a mature and reliable, The positioning method with low cost, strong anti-interference ability, high networking ability and simple operation is applied to the special environment of the power plant to improve the work safety of the power plant staff
