Using STM32 chips, communicated with SM1 encryption/decryption modules by ISO7816 interfaces;Remote signalling interface has two-way, connects respectively
External redundant current operated protective device and data acquisition unit, are forwarded or the passive remote signalling letter of filtering external according to communication need
Number, the RS485 interfaces have two-way, and external redundant current operated protective device and data acquisition unit are connected respectively, according to communication need
Asking carries out authentication, data deciphering, data transparency forwarding capability, and the infrared communication mouth supports that the residual current to being connect is moved
Data reading system is carried out as protector, the status indicator lamp can indicate power supply status and communications status information;Main control module with it is remote
Journey main website encryption equipment coordinates carries out one-to-one authentication, obtains available ciphertext after serial number and hardware random number and is communicated,
SM1 encryption/decryption modules are decrypted to ciphertext；SM1 encryption/decryption modules are substantially carried out authentication and ciphertext decryption flow process, two-way
RS485 interfaces carry out isolated from power with main control module, prevent extraneous electromagnetic signals from affecting main control module, descending RS485 interfaces to connect
RCD is connect, up RS485 interfacing datas harvester, descending remote signalling interface connects residual current acting
Protector, the RCD secure communication module is connected to data acquisition unit by up RS485 interfaces, number
The message issued to long-range main website according to harvester carries out transparent forwarding, and RS485 interfaces up first receive the authentication of main website
Instruction, when protector produces passive remote signals because of action, master control module judges protector state, according to stipulations to the remote signalling
Signal is filtered or is forwarded to up remote signalling interface, and by data acquisition unit long-range main website is sent to；Infra red communication port is matched somebody with somebody
Infrared Hand-Held palm machine peripheral hardware is closed, data reading system is carried out to descending RCD, the data that copy reading is returned are according to mark
Will position information gives hand-held palm machine peripheral hardware by infra red communication port response；Indicating lamp module includes that power supply indicator and communication are indicated
