Secondary electric power supply testing system and method

Abstract

The invention discloses a secondary electric power supply testing system and method. The system comprises a multi-channel gating switch and a load unit, wherein the multi-channel gating switch comprises N relays; the load unit comprises N paths of loads; the input ends of the relays are connected with the corresponding output ends of a controller respectively; the output ends of the relays are connected with the input ends of the loads; the output ends of the loads are in both-way connection with a main control computer through a digital multimeter and a digital oscilloscope; the main control computer is in both-way connection with the controller; input ports of the loads are correspondingly connected with all paths of a secondary electric power supply to be tested respectively. The secondary electric power supply testing method can rapidly finish testing the secondary electric power supply, excessive testing of personnel is not needed, requirement for a large amount of testing is met, and the advantages of convenience, high efficiency, rapidness and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of secondary power supplies, in particular to a secondary power supply testing system and testing method. Background technique [0002] The secondary power supply is a device that transforms the main power supply into another or more forms or specifications of electric energy to meet the needs of different electrical equipment. It can provide the required power for various electronic modules in the aircraft. For aerospace equipment, the performance of each parameter must meet the technical indicators, and the secondary power supply can only be put into use after passing strict tests and passing the test. At present, manual testing is a widely used testing method for secondary power supplies. During measurement, measurement personnel need to operate various testing instruments to test one by one according to requirements. This method is relatively primitive, and there are a series of problems: [0003] 1. ...

AI Technical Summary

Problems solved by technology

[0003] 1. Low work efficiency

When the test items are complex or there are too many circuits, testers have to build test circuits one by one, switch equipment, and record test data item by item, which is too much work and consumes manpower and material resources

[0004] 2. The test results are quite different

Since the entire testing process is done manually, the results are easily affected by human factors and may cause misjudgment

In addition, the selected test equipment is different, and the results will also have certain differences.

[0005] 3. Data processing is difficult

In the production process of the product, it is often necessary to make a statistical summary of the test data. If it is done manually, the workload will undoubtedly be too large and the work will be difficult.
