Auxiliary microcomputer measurement and control device with data storage and remote transmission expansion design

Abstract

The invention relates to an auxiliary microcomputer measurement and control device of a locomotive / bullet train (including a high-speed train) group train auxiliary system, in particular to an auxiliary microcomputer measurement and control device with data storage and remote transmission expansion design. The problems that when an existing auxiliary microcomputer measurement and control device stores operation state data of an auxiliary system, the real-time performance is poor, and remote data sending cannot be achieved are solved. The auxiliary microcomputer measurement and control device comprises a control board card, a digital quantity board card, an analog quantity board card, a network board card and a backboard, wherein the control board card, the digital quantity board card, theanalog quantity board card and the network board card are inserted into the backboard to realize mutual connection; an external expansion RAM chip and a nonvolatile FLASH chip are arranged on the control board card and are used for assisting the storage of system data; the system also comprises a 4G gateway board card, and the 4G gateway board card achieves the data communication with the cloud server through an antenna. The ground control center is provided with a server or a mobile terminal, and the server or the mobile terminal communicates with the cloud server and downloads data from thecloud server.

Description

technical field [0001] The invention relates to an auxiliary microcomputer measurement and control device for a train auxiliary system of a locomotive / motor train (including high-speed rail), in particular to an auxiliary microcomputer measurement and control device with data storage and remote transmission expansion design. Background technique [0002] The auxiliary microcomputer measurement and control device is used to control the auxiliary system of the locomotive or EMU train. In addition to completing the control of the auxiliary system power supply and realizing the function of supplying power for the auxiliary system, another important function of the auxiliary microcomputer measurement and control device is to complete the auxiliary system. Real-time monitoring of system operating status. This kind of real-time monitoring of operating status is mainly aimed at the core device of the auxiliary system - the auxiliary system power supply (generally the auxiliary conve...
