Serial communication board and its realization method for microcomputer control system of electric locomotive

Abstract

The invention discloses an electric locomotive microcomputer control system serial communication plate and an achievement method thereof. The electric locomotive microcomputer control system serial communication plate comprises a power source module, a CPCI (Compact Peripheral Component Interconnect) communication module and a data interface module; the CPCI communication module is used for performing initialization configuration on a communication main control module to achieve data transmission with a processor of the locomotive microcomputer control system in real time after the initialization configuration is achieved; the communication main control module is used for configuring a plurality of mutually independent data transmission channels to perform data transmission after the initialization configuration, meanwhile detecting data transmission information of data transmission channels during a data transmission process and controlling data transmission processes of the data transmission channels in combination with the data transmission information and a preset data transmission logic control mechanism; data transmission is achieved between the data interface module and controlled units inside the locomotive microcomputer control system. The electric locomotive microcomputer control system serial communication plate is high in integration level, strong in universality and easy to maintain and can guarantee the high reliability and the strong instantaneity of communication between the electric locomotive microcomputer control system and other units.

Description

technical field [0001] The invention relates to a remote input and output unit of an electric locomotive, in particular to a serial communication board of an electric locomotive microcomputer control system and a method for realizing reliable data transmission between the electric locomotive microcomputer control system and other units of the locomotive. Background technique [0002] During the running of the locomotive, it is required to be able to transmit data between the locomotive microcomputer control system and other units of the locomotive, and to be able to display the current locomotive working condition and various fault information on the driver display unit in time, that is, it is necessary to ensure the stability and real-time data transmission of each unit sex. [0003] At present, the remote input and output unit of the electric locomotive is mainly used to realize the data transmission and control among the units in the locomotive. The structural size of eac...

Problems solved by technology

[0004] However, the FIP bus communication board lacks versatility, and the chips used in the board have been discontinued. The cost is expensive and is also limited by various conditions such as communication mode and speed. Therefore, the FIP of the remote input and output unit of the existing model electric locomotive The bus communication board cannot meet the actual needs of the communication between the units of the new electric locomotive
