Some unit utilizes the GPS global satellite positioning that earth connection is positioned tracing management, but the longitude and latitude positioning accuracy of GPS location is the highest only to about 10 meters at present, can't satisfy the accurate positioning requirements of earth connection in the transformer station, and cost is higher.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned prior art, aim to provide a kind of based on temporary ground wire user mode monitoring early-warning system in the transformer station of Wi-Fi placement technology.
The technical scheme that the present invention realizes is:
The transformer substation grounding wire condition monitoring system comprises supervising device, positioner and a plurality of wireless local network connecting point AP, and supervising device is communicated by letter with positioner through wireless local network connecting point AP and is connected;
Described wireless local network connecting point AP, the locating information of collection and forwarding positioner;
Described supervising device mainly comprises server and wireless router, and server is connected with wireless router through the LAN in the transformer station; Described server is used for the locating information of receiving positioner;
Described wireless router is used for the conversion of data between heterogeneous networks, and wireless router is communicated by letter with wireless local network connecting point AP with server respectively and is connected;
Described positioner is installed on the earth connection, mainly is made up of low-power consumption Wi-Fi wireless singlechip module, wireless communication module, supply module.
Useful technique effect of the present invention is: the present invention utilizes positioner that earth connection is carried out unique identification; And the coded message and the positional information of earth connection transferred to server through the Wi-Fi cordless communication network; Judge that according to the positional information of earth connection earth connection is " articulating " or states such as " dismountings "; Before closing a floodgate after maintenance is accomplished; If exist the earth connection of not removing then to issue warning message immediately, fundamentally stop the potential safety hazard that the ground wire misoperation brings, guaranteed the on-the-spot correctness of using of earth connection; When preventing because of construction operation not hanging earthing conductor, mistake hanging earthing conductor, in time do not remove earth connection when construction finishes, omit and remove the generation that earth connection causes a series of security incidents, the fail safe that improves electrical network.
The positioner of installing on the earth connection among the present invention need not read write line through Wi-Fi wireless network transmissions data, can not produce other wireless devices and disturb, and can make full use of the existing local area network (LAN) facility of transformer station, reduces cost greatly.
