Along with the continuous propelling that intelligent grid is built, the detection & localization problem of distribution network failure, more and more receives publicity.How to build suitable system and localization of fault is detected the problem brought in the construction of modern power network and become in power industry and needed research emphatically and solve.
The actual fault detector used was based on mechanical type in recent years.Because mechanical type cannot communicate form effective fault location system, so poor for the effectiveness comparison of localization of fault, need to coordinate artificial line walking to position, the slow efficiency of speed is low.Meanwhile, for non-effectively earthed system, mechanical type generally cannot detect.So people start the development paying close attention to electronic fault indicator.Electronic type by communication network consisting, can make system be called an organic whole, in localization of fault process, plays huge advantage.
At present, electronic type fault detector has had significant development, but electronic type fault detector cannot directly by data remote to main website, therefore the main website that cannot receive data also cannot realize localization of fault.
Utility model content
The purpose of this utility model is exactly provide to overcome defect that above-mentioned prior art exists the fault data concentrator based on radio communication that a kind of data transmission efficiency is high, operation is convenient, security is high, as communication bridge and the data relay of electronic type fault detector and main website, all numbers of fault detector are all needed to carry out arrangement fault data by data concentrator and reports main website, realize main station failure location, significant for fault location system.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fault data concentrator based on radio communication, this concentrator communicates with electronic type fault detector with main website respectively, it is characterized in that, described data concentrator comprises MCU, GPRS wireless communication module, 433M wireless communication module, LED indicator, watchdog circuit, ferroelectric memory module, RS232 interface module and power module, and described MCU is connected with GPRS wireless communication module, 433M wireless communication module, LED indicator, watchdog circuit, ferroelectric memory module, RS232 interface module and power module respectively.
Described GPRS wireless communication module comprises the metal-oxide-semiconductor be connected with MCU.
Described 433M wireless communication module comprises the metal-oxide-semiconductor be connected with MCU.
Described GPRS wireless communication module is connected with main website; Described 433M wireless communication module be connected electronic type fault detector and connect.
Compared with prior art, the utility model has the following advantages:
1, in the process of mechanical type fault detector to the transition of electronic type fault detector, the utility model, along with the application of electronic type fault, has filled up the blank of application.
2, device adopts the design of ultra-low power consumption wireless sensing network, long service life.
3, device wire communication mode and communication use.
