Problems solved by technology

[0016] Some of the board position identification methods of existing plug-ins are realized by setting broadcast code switches on the plug-ins. When using them, the switch status needs to be set. When the number of plug-ins used is large, setting the switches is time-consuming and very error-prone
Some are implemented by setting the plug-in board position on the motherboard, but only a single CPU is used for collection, and the reliability and security are not high.

Abstract

The invention discloses a platform plug-in with board position identification function, so that the host plug-in on the platform can effectively identify the position information of the plug-in installed on the subrack, and compare it with configuration data to perform corresponding security processing. The technical solution is to design a platform plug-in with a board position identification function, and after the plug-in is inserted into the subrack and powered on, the read board position identification code is sent to the platform host plug-in. The host plug-in can effectively identify the location information of the plug-in installed on the subrack, and compare it with the configuration data for corresponding security processing.

Description

technical field [0001] The invention relates to a platform plug-in, in particular to a platform plug-in with board position identification function. Background technique [0002] In traffic control systems such as high-speed railways, there is a core device called a safety computer that ensures the safe operation of trains. The safety computer specifically realizes the real-time control and safety protection of train operation, ensuring that the train runs within the allowable range according to the designed route and expected speed. In order to achieve this goal, the safety computer needs to monitor the operating parameters of the train in real time, such as the running speed, current position, train operating instructions, and the internal state of the system. Through these operating parameters, operators or system maintenance and debugging personnel can keep abreast of the system operating status and equipment status, and give follow-up control commands based on this. ...
