Abstract

The invention belongs to the technical field of detection, and discloses a program controller comprehensive test device and a program controller comprehensive test method. The program controller comprehensive test device is composed of a comprehensive tester, a comprehensive test bench and a vacuum pump, wherein the comprehensive tester comprises a pressure sensor, a power supply module and a circuit board assembly. According to the program controller comprehensive method, a modular design scheme is adopted, a tested product is precisely clamped and positioned in the device, an identifier is clear, a single-chip microcomputer micro-processing technology is adopted for controlling and a grating technology is adopted for monitoring the action time, and the operation of listening to a manualcontrol electric second chronograph for testing is replaced; pneumatic clamping, locking and unlocking of a vacuum box are achieved and replace the technical methods of manual pulling and locking. Theprogram controller comprehensive test device and the program controller comprehensive test method are high in test precision, convenient to operate and use and capable of thoroughly eliminating mercury pollution, the use requirements of users for testing various products can be met by one device, and the device has the advantages of wide application range, strong universality, good expansibilityand convenience in operation.

Description

Technical field [0001] The invention belongs to the field of detection technology, and is a comprehensive testing device and a testing method for a program controller. Background technique [0002] The company’s new aviation products require various aspects of testing and inspection during the development. Outdated testing equipment, its testing accuracy and testing efficiency no longer meet the needs of modern production. [0003] The existing product is the УКПА detection device produced in Russia, which uses a double-needle altimeter visual inspection and manual operation. This test method has low test accuracy, cumbersome operation, and environmental pollution caused by the mercury altimeter. Summary of the invention [0004] The technical problem to be solved by the present invention is to propose a test device for testing the working height and airspeed time of the program controller, which has high test accuracy, simple operation and no environmental pollution. [0005] The t...
