Comparison circuit is crossed, judges switch for leakage protector current state.（Fig. 3）
The comprehensive analysis module mainly includes：STM32 microprocessors.By stm32 handle transmission Lai data.Flow chart is such as
Figure（7）.The data of decision circuitry are handled, judging result is divided into 1（It is closed）With 0（It disconnects）If being closed, instruction is provided, return takes
Sample end continues to sample.If disconnecting, instruction is provided, data in synthesis analyser will be deposited with and, by output terminal, be sent to transmission and set
It is standby.Figure（4）
The sending device module：It is a duplicate circuitry, mainly the actual physical address deposited in a register is carried out
It sends.It is sent to fixed receiving device.Figure（5）
The receiving device module：It is a duplicate circuitry, mainly receives data, and data transmission is sent to STM32,
Data are analyzed, obtain specific physical address, implement operation.Figure（6）
The invention has the beneficial effects that：Existing hierarchical structure is changed to platypelloid type structure, network topology structure is star
Type structure, based on the database of computer, using information system and information management as core, using wireless communication technique as Jie
Matter with specific communication apparatus, completes the function to step down side earth leakage protective device tripping remote alarms.For electric system
The exploitation of intelligent maintaining power grid is laid a good foundation, and also realizes that management information system lays the foundation comprehensively for electric system.
