Problems solved by technology

At present, the test of this kind of driving system is mainly manual test, which has the following disadvantages: (1) Due to the manual test, there may be cases where the test is not in place, there may be omissions, and even the expected verification effect cannot be achieved
(2) The essence of manual testing is still empirical behavior, which requires extremely high ability of testers. At the same time, there is a lack of unified norms and standards, and there is limited room for improvement in terms of quality and efficiency.

Embodiment 1

[0047] Such as figure 1 As shown, a test system for a signal drive system, the signal drive system includes a signal machine SC, a signal drive module SDDM, and an all-electronic communication module EIOCOM2 connected in sequence. The test system includes a simulated interlocking lower computer IPS, The simulated interlocking maintenance platform SDM and the test platform TP; the simulated interlocking lower computer IPS and the simulated interlocking maintenance platform SDM are connected to the full electronic communication module EIOCOM2, and the test platform TP is connected to the signal machine drive module SDDM and the full electronic communication Module EIOCOM2 connection.

[0048] In this embodiment, it is a test system of a signal drive system based on a two-by-two architecture, so there are two signal drive modules SDDM: a signal drive module SDDM_A and a signal drive module SDDM_B; an all-electronic communication module EIOCOM2 Both have two: the full electronic ...

Embodiment 2

[0069] In this embodiment, the test system of the signal drive system based on the two-by-two architecture is used to verify a specific process of the multi-way switch BIT in the signal drive module SDDM, including the following steps:

[0070] Step 1. In the power-on and power-off module, power on the signal driver module SDDM;

[0071] Step 2. In the fault injection module, respectively simulate the sixth switch CPUA switching failure, CPUB switching failure, CPUA and CPUB simultaneous switching failure;

[0072] Step 3. In the online programming module, open the content of the multi-way switch fault injection according to the test script, and perform online programming of the signal driver module SDDM;

[0073] Step 4. After the programming is completed, power off the signal driver module SDDM by powering on and powering off the module, and then power on again;

[0074] Step 5, through the online recording and analysis of the log module, verify whether the BIT is successfu...

Abstract

The invention relates to the test system and method of a signal machine driving system. The signal machine driving system comprises a signal machine SC, a signal machine driving module SDDM, and an all-electronic communication module EIOCOM2 which are successively connected. The test system comprise a simulated interlocking lower computer IPS connected to the all-electronic communication module EIOCOM2, a simulated interlocking maintenance bench SDM connected to the all-electronic communication module EIOCOM2 and a test platform TP connected to the signal machine driving module SDDM and the all-electronic communication module EIOCOM2. Compared with the prior art, by using the system and the method of the invention, the signal machine driving system can be automatically tested, the manpowerof verification personnel is liberated, and simultaneously the signal machine driving system can be high-efficiently tested and analyzed so as to ensure the quality of a test.

Description

technical field [0001] The invention relates to the technical field of railway traffic testing, in particular to a testing system and method for a signal machine driving system. Background technique [0002] With the rapid development of my country's rail transit industry, more and more stations use high-performance circuit boards to replace the complex and numerous relays in the past to realize the driving and collection of signal lights, that is, to use this two-by-two-out-of-two structure signal machine The drive system is used to realize the drive and collection functions of single or combined signal lamps. The construction of this new driving system is simple, but the safety must be guaranteed. Once a defect occurs, it will cause immeasurable property losses and casualties. [0003] Therefore, a test method for a signal drive system based on a two-by-two architecture is particularly important. At present, the test of this drive system is mainly manual testing, which ha...
