Abstract

The embodiment of the invention provides an input and output signal acquisition system and a test method. The system comprises an input and output module, a relay module, a first central control unitand a second central control unit, wherein the input and output module is connected with the first central control unit and the second central control unit through the relay module; the input and output module comprises a communication control board, a digital quantity input board and a digital quantity output board; the communication control board is connected with the digital quantity input board through a first bus and a second bus; the communication control board is connected with the digital quantity output board through a third bus and a fourth bus; the communication control panel further comprises a first port and a second port; the relay module comprises a first board card and a second board card; a port on the first board card is connected with a first port on the communication control board; and a port on the second board card is connected with a second port on the communication control board.

Description

technical field [0001] The invention relates to the technical field of train communication, in particular to an input and output signal acquisition system and a test method. Background technique [0002] The train on-board network information system is a comprehensive, modular and integrated system, so it puts forward higher requirements for the protection mechanism. [0003] The on-board network information system of the train includes an input and output signal acquisition system, and the input and output signal acquisition system is used to collect the input and output signals of the related equipment in the train. In the input and output signal acquisition system, the CCU (Central Control Unit, central control unit) needs to communicate with the IOM (Input / Output Module, input and output module) through ETH, collect the control instructions and equipment status information fed back by the IOM in real time, and send it to the IOM. Therefore, the collection of IOM signals...
