Product input power supply switching product non-power-down automatic test system and method

Abstract

The invention relates to a product input power supply switching product non-power-down automatic testing system and method. The system comprises a 50Hz alternating-current power supply, a 60Hz alternating-current power supply, a power supply switching device, a servo voltage regulator, an electrical parameter tester, an electronic load and a temperature rise recorder. The 50Hz alternating-currentpower supply and the 60Hz alternating-current power supply are connected in parallel and then are connected with the power supply switching device; the power supply switching device is connected withthe servo voltage regulator; the servo voltage regulator is connected with the electrical parameter tester; the power supply switching device, the servo voltage regulator and the electrical parametertester are respectively connected with a computer through circuits; the electrical parameter tester is connected with a test sample; the test sample is respectively connected with the electronic loadand the temperature rise recorder through circuits; and the electronic load and the temperature rise recorder are respectively connected with the computer through circuits. Compared with the prior art, the sample can be shut down without power failure in the whole test process, and an operator can complete the test of the whole test process only by performing product function setting once.

Description

[technical field] [0001] The invention belongs to the field of electrical safety testing, and specifically relates to an automatic testing system and method for switching products without power failure when inputting power to a product. [Background technique] [0002] There are many types of electronic and electrical products with different functions. In terms of functions, some products can be restored to the last working state after restarting after power off, while some products require complex settings to restore to the last working state. The working state of the product, or the self-inspection can enter the normal working mode after power-on, (for example: computer, network camera, etc.). The temperature sensor is pulled and damaged, which brings great inconvenience in the test, and the input and output parameter test, normal temperature rise, abnormal temperature rise and fault temperature rise test in the electrical safety test, each voltage and each temperature meas...

Problems solved by technology

[0015] In the above test process, each time the input power is switched, the tester needs to set the function of the product. The connection of the software is the same as the setting, and the product function will be in the normal working mode. The test depends heavily on the participation of the personnel, and the test efficiency is low; In the field of testing, the market lacks a test system that does not turn off the power of the sample during the input power switching process, and cannot realize automated process testing.
