Embodiment Construction

[0031] The TCMS-MPU control unit with safety level design is composed of 3U chassis, power board, main control board MCPU, network board NET1, backplane and blind board. Among them, the power supply board can convert the DC77V~DC137.5V power supply of the vehicle into stable DC5V and DC3.3V, and input them to each board through the backplane; the main control board is designed with RS232, USB and Ethernet communication interfaces, Complete functions such as running status monitoring, program upload and download; the network board is designed with communication interfaces such as MVB and CAN to realize the interaction of bus network data.

[0032] The hardware appearance of the TCMS-MPU control unit with security level design is as follows: figure 2 shown.

[0033] The board layout of the TCMS-MPU control unit is shown in Table 1:

Abstract

The invention relates to a TCMS-MPU control unit, in particular to a TCMS-MPU control unit with a safety level design. The problem that the safety and reliability of an existing TCMS-MPU control unitneed to be improved is solved. The TCMS-MPU control unit with the safety level design comprises a power supply board card, a main control board card, a network board card and a backboard; data interaction is carried out between the main control board card and the network board card through a CPCI board-level bus on the backboard. The power supply board card supplies power to the main control boardcard and the network board card through the backboard; the safety design comprises the steps that an MCU1 function module of the main control board card monitors a main processor CPU of the main control board card in real time, and a CPLD function module of the network board card monitors the execution condition of the network board card; according to the TCMS-MPU control unit, the requirements of EN50126 and EN50129 are met, the safety level of the control unit is improved, and dual-MPU hot standby redundancy control is achieved by designing the same master control MPU1 and slave control MPU2 through a safety loop.

Description

technical field [0001] The invention relates to a TCMS-MPU control unit, in particular to a TCMS-MPU control unit with safety level design. Background technique [0002] TCMS (Train Control and Management System) is composed of communication, control, man-machine interface and other devices and supporting cables and connectors, such as figure 1 shown. [0003] TCMS adopts the TCN bus based on the IEC 61375 standard, which is composed of the train bus WTB and the vehicle bus MVB secondary bus. It is an on-board microcomputer control system for locomotive control, monitoring and diagnosis. The central control unit MPU is the core component of TCMS, which carries the realization of the vehicle control function and completes the bus management and locomotive logic control of the entire network. The TCMS-MPU control unit is the core component of the vehicle TCMS network control system, which belongs to MVB 4 types of equipment. It performs data interaction with various subsyste...
