specific Embodiment approach 1

[0026] Specific implementation mode 1. Combination Figure 1 to Figure 8 Describe this embodiment, the CRH5 type EMU reconnection simulation debugging device, the debugging device in this embodiment is connected with the CRH5 type high-speed EMU through interfaces such as reconnection coupler, WTB bus, CAN bus, UIC568, RS485 bus, etc., and with The train realizes data exchange. At the same time, it can communicate with the monitoring computer of the running test software through the Ethernet ETH interface, and can be used to receive various control commands issued by the CRH5 EMU, and monitor the running status of the train, so as to complete the train reconnection test. The main functions include: On-board equipment function test, equipment operation status monitoring, fault early warning and alarm, train end hard-wire signal simulation, etc. Specifically include: reconnection network communication test, reset test, hot axis test, parking brake application, mitigation test, ...

specific Embodiment approach 2

[0041] Embodiment 2. This embodiment is an example of using the CRH5 EMU reconnection simulation debugging device described in Embodiment 1 for testing:

[0042] The large reset test process in the routine test project is as follows:

[0043] Connect the coupler connector tooling 7 to the vehicle coupler, and the test personnel press the "big reset" button on the vehicle to start the test when the vehicle is not occupying the head. The digital input board 3-2 in the terminal IO device 3 collects the signal of the corresponding pin on the reconnection coupler, and the digital input board 3-2 transmits the "large reset signal" collected from the coupler to the terminal through the CAN bus The main processor board 3-1 in the terminal IO device 3 processes data, converts it into Ethernet data, and finally converts it into Ethernet data by the main processor board 3-1 in the terminal IO device 3 and transmits it to the monitoring computer 2 displayed on the monitoring software.

Abstract

The CRH5 EMU reconnection simulation debugging device involves the technical field of EMU maintenance and test technology. In order to solve the complex problems that cannot be solved in time in the existing EMU reconnection test process, it is difficult to guarantee the quality of maintenance and the test is not comprehensive. And problems such as poor versatility, provide a CRH5 type EMU reconnection simulation debugging device, including the thermal axis main engine integrated in the movable cabinet, monitoring computer, terminal IO device, PIS simulation test device, Ethernet switch, reconnection gateway and coupler connector tooling; the CRH5 EMU reconnection simulation debugging device described in the present invention is small in size, light in weight, and easy to move, and can effectively avoid high-risk operations such as repeated pulling of EMUs, detachment of reconnection, and backtracking. And it can reduce the labor intensity of workers and improve the utilization rate of the plant. The construction and maintenance are convenient, the man-machine interface is friendly, the operation is simple, the production efficiency is improved, and the maintenance / debugging cycle is shortened.

Description

technical field [0001] The invention relates to the technical field of overhauling and testing of EMUs, in particular to a CRH5 type EMU reconnection simulation debugging device. Background technique [0002] During the advanced repair of EMUs, there is often the problem that there is no other vehicle to cooperate with the reconnection test. As a result, the EMU cannot be delivered to users on time after the repair is completed, which seriously affects the repair cycle. The existing solutions are as follows, but they all have obvious shortcomings: [0003] Option 1: Wait for other repaired vehicles to cooperate with the reconnection test. Due to the uncertainty in the time of the repaired vehicles, it will inevitably affect the maintenance progress; [0004] Option 2: After the maintenance, the vehicle is directly delivered to the depot, and the reconnection test is carried out at the application site. However, if complex problems are found and cannot be eliminated in time,...
