Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to an ice detector testing platform. Background Art

[0002] The ice detector is used to detect the icing of the aircraft in time after the aircraft enters the icing gas phase environment and give an icing warning signal to the flight control system after icing. This type of ice detector needs to be tested for performance such as working frequency, energy consumption, and low temperature operation during the assembly and acceptance process. At present, the performance test of this series of products is completed by DC power supply, oscilloscope, tester, digital multimeter, micro-ohmmeter and other equipment. During the test, the operator inputs signals to the product by turning certain switches on the tester, and judges whether the product test is qualified by the indicator light status on the tester and the product feedback data. Since the product status is different under each test item, the operator needs to repeatedly turn the switch on the front panel of the tester, and the resistance measurement and other work are all done manually. The test data needs to be recorded manually. The test time of each product is as long as 30 minutes. Therefore, the traditional test method has the disadvantages of long test process, complicated operation, and untraceable test data. The use of the test platform can complete the automatic test of the entire product process, avoiding the problem of workers copying the wrong data when manually recording data. The use of the test platform test can reduce the test time of the original product from about 30 minutes to about 20 minutes. Summary of the invention
