Electronic switch temperature rise detection system and method

Abstract

The invention relates to the field of electronic switch temperature rise testing, and particularly relates to an electronic switch temperature rise detection system and method. The electronic switch temperature rise detection system comprises a computer control terminal, a programmable logic controller, a temperature data collector, a thermocouple, a variable-frequency power supply, an electronic switch, an AC contactor and a load, and is characterized in that a user sets a test program and test parameters through the computer control terminal, output parameters of a test power supply are automatically controlled, and the AC contactor is automatically controlled to connect a corresponding test load through the programmable logic controller, thus automatic setting of parameters of the test power supply and automatic connection of the test load are realized, temperature data is collected through the temperature data collector, the temperature data is judged and processed by the program of the computer control terminal, a next test step is automatically joined when temperature values of all tested points reach a preset stability condition, and a test result form is generated automatically. The system and the method provided by the invention can improve the detection efficiency, shorten the detection period, reduce manpower resources and reduce the detection energy consumption.

Description

technical field [0001] The invention relates to the field of temperature rise testing of electronic switches, in particular to a temperature rise detection system and method for electronic switches. Background technique [0002] With the rapid development of electronic technology and the increasing demand for high-tech intelligent products, the development and application of electronic switches are in a stage of rapid development, which puts forward higher requirements for the detection of electronic switches. The temperature rise test is an important test item in the type test of switch products, and it is one of the test items that require the most human intervention, take the longest time, and have the weakest test consistency, especially for electronic switches. [0003] At present, the domestic switch temperature rise test mainly adopts manual or semi-automatic methods, not only the test efficiency is low, but the accuracy of the test results depends on the technical le...

[0003] At present, the domestic switch temperature rise test mainly adopts manual or semi-automatic methods, not only the test efficiency is low, but the accuracy of the test results depends on the technical level and experience of the test personnel

Since the electronic switch temperature rise test involves a combination of various parameters, in order to find the most unfavorable test conditions, it is often necessary to change a certain parameter while other parameters remain unchanged and perform repeated tests, such as changing the load type or changing the switch A certain set value of a certain set value, such a combination sometimes reaches more than a dozen. If the existing equipment is used for the test, the whole process will be very complicated, there will be a lot of manpower, a long test cycle, and difficult operation leading to a high error rate. Too much power consumption and many other deficiencies
