System and method for testing multi-user parallel of locomotive switch power supply

Abstract

The invention discloses a system and a method for testing multi-user parallel of a locomotive switch power supply. A first direct current power supply, a second direct current power supply, an alternating current power supply, a first direct current load, a second direction current load, third to mth direct current loads and a detecting device are connected through a control bus; and n external interfaces are connected with the first direct current power supply, the second direct current power supply, the alternating current power supply, the first direct current load, the second direction current load, the third to the mth direct current loads and the detecting device through a lead and is connected with a computer through a control bus. The value of m is determined according to a maximum value of output numbers of the power supply of the switch to be tested; and n external interfaces are connected with the power supplies of n switches to be tested through n transition harnesses. A multi-user configuration mode is adopted in the computer and the computer comprises a plurality of user configuration modules. With the adoption of the system and the method, the technical problems that resource utilization rate is not high in the prior art, only one switch power supply of the locomotive is tested at one time and only one person is allowed to use the resource of a locomotive switch power supply testing system at one moment are solved.

Description

technical field [0001] The invention relates to an electrical testing system and a method thereof, in particular to a multi-user parallel testing system and method for a locomotive switching power supply applied to electrified rail transit equipment. Background technique [0002] The current locomotive switching power supply has the following characteristics: (1) There are two types of input: AC (alternating current) and DC (direct current); (2) The input voltage, input undervoltage protection value, and input overvoltage protection value of different locomotive switching power supplies are different. And the difference is very large; (3) The output voltage of different locomotive switching power supplies is different and the requirements for load are different; (4) The number of output voltage circuits of different locomotive switching power supplies is different, and the difference is very large. In order to adapt to these characteristics of the locomotive switching power ...

AI Technical Summary

Problems solved by technology

[0003] (1) The test system has relatively rich resources. When testing a specific locomotive switching power supply, the test system only uses a part of the resources, and the rest of the resources are idle, so the utilization rate of the test system resources is not high;

[0004] (2) At the same time, even if some switching power supplies with less resource requirements cannot be tested at the same time, they can only wait

[0007] (1) The resource utilization rate is not high. When only testing each type of locomotive switching power supply, the resources of the locomotive switching power supply test system are left (unused) to varying degrees;

[0008] (2) Only one locomotive switching power supply can be tested at a time, even if the remaining resources meet the requirements, it can only wait;

[0009] (3) Only one person is allowed to use the test resources of the locomotive switching power supply test system at the same time
