Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] It is a test platform for two-by-two vehicle-mounted software of one of the present invention, comprising: two train driving display TODs, two VOBCs loaded with vehicle-mounted software, a device loaded with ES software for simulating trackside equipment, and a SimPPU loaded device, a device loaded with emulation SD software, and a device loaded with ATS software. in,

[0036] The PPU is replaced by SimPPU, but the interface between the MPU and the PPU remains unchanged, and the CAN bus is still used. Use the simulated SD software Port Forwarding instead of SD. ES software for simulating trackside equipment communicates with SimPPU through TCP / IP to provide input and output signals for SimPPU. SimPPU transmits these signals to MPU through CAN bus. In this way, through a specific network communication protocol, SimPPU can package and transmit complex hard-wired IO...

Abstract

The invention discloses a testing platform for double-two-out-of-two vehicle-mounted software. The testing platform comprises two train driving displayers, two VOBCs loaded with the vehicle-mounted software, a device loaded with ES software, a device loaded with a SimPPU, a device loaded with simulation SD software, and a device loaded with ATS software. PPU hardware is not needed, and various double-two-out-of-two function tests can be carried out on the double-two-out-of-two vehicle-mounted sub-rack and the software only through basic hardware connection. The invention further discloses a testing platform for the double-two-out-of-two vehicle-mounted software. The testing platform comprises two train driving displayers, a first VOBC, a second VOBC, a device loaded with ES software, a PPU, SD equipment, a device loaded with a SimPPU, a device loaded with simulation SD software, and a device loaded with ATS software. The performance of real hardware equipment and the performance of the simulation hardware equipment can be compared and analyzed, and therefore the requirement for the stability of the system is higher.

Description

technical field [0001] The invention relates to the field of train control, in particular to a test platform for two-by-two-out-two vehicle control system software. Background technique [0002] In the communication-based train control system, Vehicle On Board Cotroller (VOBC), as the core subsystem of train control, is directly related to the safety of train operation. The two-by-two-out-two vehicle control system (2x2oo2VOBC) not only makes redundancy for the main controller unit (MPU, Main Processer Unit), but also makes redundancy for the response interrogator (TI, Tag Investigator), proximity sensors and other equipment, Therefore, more and more customers have requested to adopt the two-by-two vehicle-mounted control system. [0003] In order to effectively test 2x2oo2VOBC, the existing test platform is equipped with two sets of MPUs for running 2x2oo2VOBC software, processing external input and output through an external interface processor unit (PPU, Peripheral Proce...
