Description

technical field [0001] The invention relates to the technical field of frequency converter testing, in particular to a testing system and method for frequency converters of door machines. Background technique [0002] The door machine inverter is the drive for the door machine system of the elevator. The inverter of the door machine must be strictly tested before leaving the factory to ensure that the function of the inverter is free from defects. The test items of the door machine inverter mainly include door signal test, door load test, etc. At the same time, for some door machine inverters equipped with a forced air cooling system, the test of the forced air cooling system is also essential. [0003] The traditional door machine inverter test needs to build a door system to provide door signals, etc., and for door machine inverters with different powers, because the drive module of the drive (inverter) needs to be tested, different elevator door systems need to be built....

AI Technical Summary

Problems solved by technology

[0003] The traditional door machine inverter test needs to build a door system to provide door signals, etc., and for door machine inverters with different powers, because the drive module of the drive (inverter) needs to be tested, different elevator door systems need to be built. Lead to a large test area and high cost

For some door inverters that support both asynchronous motors and synchronous motors, the motors on the door system need to be replaced, which affects the stability of the entire door system and the test efficiency is low

In addition, since the elevator door system built is a mechanical device, the requirements for protective measures are relatively high. If the protective measures are not taken well, it is easy to cause the risk of work-related injuries during the test.

[0004] The traditional method of testing the forced air-cooled heat dissipation system of the door machine frequency converter, because the frequency converter adopts a fully enclosed design, it is difficult to detect the start of the fan, so the tester presses the shell of the frequency converter by hand, and carefully distinguishes whether there is vibration. , this test method is very unreliable, prone to missing or misjudgment

[0005] The traditional testing method is manual testing, which requires testers to manually input a large number of parameters. In addition, there are many testing steps, which makes it difficult to promote in production testing. When there is a change in test items, it is necessary to issue production test files and conduct on-site training. There is a waste of manpower and material resources

In addition, after the test is over, testers need to manually fill in the test data, it is not suitable to record detailed test data, and it is difficult to meet the needs for analysis of test results
