specific Embodiment approach 1

[0038] A kind of equipment mainframe system used for locomotive signal on-board system of the present embodiment, the board card on the described equipment host system comprises recording board and mainboard, and recording board and mainboard are all provided with CPU and serial communication bus, and recording board The CPU FLASH area of ​​the motherboard and the motherboard are divided into two independent areas without address overlap: programming program area and application program area; the recording board and the motherboard are connected through a serial communication bus; the CPU on the recording board and the motherboard The CPUs on the board respectively obtain the application program through the serial communication bus;

[0039] in,

[0040] The burning program area is used to store the burning program, use the burning program to erase the original application program in the application program area, and write the cached new application program to the application ...

specific Embodiment approach 2

[0043] The difference from Embodiment 1 is that, in this embodiment, a host system for vehicle signaling vehicle system equipment, the CPU on the recording board and the CPU on the mainboard both use digital signal processors DSP.

specific Embodiment approach 3

[0044] The difference from the second embodiment is that, in this embodiment, a host system used for on-vehicle signaling system equipment, the programming area is also used for receiving and forwarding new application programs.

Abstract

The invention discloses a host system of locomotive signal vehicle-mounted system equipment and a program changing method thereof, and belongs to the field of railway signals. An existing locomotive signal vehicle-mounted system equipment host program changing method is tedious in operation, has a fault risk and affects railway operation safety. The method comprises the following steps: dividing arecording board in a host of the locomotive signal vehicle-mounted system equipment and FLASH in a CPU of a mainboard into an application program area and a programming program area; Host during operation, the other external equipment establishes direct communication or indirect communication with a CPU (Central Processing Unit) of which the program needs to be changed through a serial communication bus; The method comprises the following steps that a CPU (Central Processing Unit) receives a new application program and sends the new application program to the CPU, the CPU receives the new program and stores the new program in a storage area, the program jumps to a programming program area to be executed, the programming program stored in the programming program area erases an original application program in the application program area, and the new application program is programmed to the application program area. The method is convenient and fast to operate and good in reliability, and the locomotive running safety is improved.

Description

technical field [0001] The invention relates to a host system of a locomotive signal on-board system equipment and a method for updating program of the host system, in particular to an on-line program change method of the locomotive signal on-board system equipment and the system. Background technique [0002] During the on-site operation of locomotive signaling on-board system equipment, the application program in the host computer needs to be changed according to the change of on-site operation conditions or according to customer requirements. Currently, the method of changing the application in the mainframe is: [0003] After the locomotive enters the warehouse, the maintenance personnel of the locomotive signal on-board system equipment enter the locomotive, and after powering off the locomotive signal on-board system equipment, remove the recording board or main board that needs to be changed from the main engine and bring it indoors; indoors, professional Technicians...
