Abstract

The invention relates to a safety communication module of a residual current action protector. The safety communication module of the residual current action protector is provided with a main control module, an SM1 encryption and decryption module, an RS485 interface module, a remote signaling interface module, an infrared communication module, and a status indication module; the main control module communicates with the SM1 encryption and decryption module through an ISO7816 interface. Communication: The remote signal interface is connected to the external residual current action protector and data collector respectively, the RS485 interface is respectively connected to the external residual current action protector and data Current action protector, the uplink RS485 interface is connected to the data collector, and the downlink remote signaling interface is connected to the residual current action protector; the infrared communication interface cooperates with the peripherals of the infrared handheld computer, and the indicator module includes a power indicator light and a communication indicator light, and the infrared interface cooperates Handheld infrared handheld peripherals, the status indication module includes a power indicator light and a communication indicator light, which are used to indicate the communication status of the power supply, RS485 interface, and infrared interface.

Description

technical field [0001] The invention relates to a safety communication module of a residual current action protector. Background technique [0002] At present, the residual current action protector does not have the encryption and decryption function of communication hardware, and the messages for remote control after being connected to the remote monitoring system are transmitted in plain text, and the communication security is low. In order to improve the security of the remote control of the residual current action protector in the intelligent distribution transformer area, it is necessary to develop a safety communication module for the residual current action protector, and cooperate with the remote master station encryption machine to secure the residual current action protector in the intelligent station area. manipulation. Contents of the invention [0003] The purpose of the present invention is to provide a safety communication block of a residual current action...
