Embodiment Construction

[0053] The specific implementation of the switch control method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] In one embodiment, a switch control method is provided, referring to figure 1 said, figure 1 It is a flow chart of the switch control method in one embodiment, including the following steps:

[0055] Step S101, collecting the test voltage signal of the voltage input port of the device under test;

[0056] Wherein, the test voltage signal refers to the test voltage signal input by the test voltage source to the voltage input port of the device under test when the device under test is tested, and the test voltage signal may include voltage signals of sine wave, square wave or triangular wave.

[0057]This step is mainly to collect the test voltage signal at the voltage input port of the device under test, and then obtain information such as voltage amplitude, phase value, frequency or period of the te...

Abstract

The invention relates to an on-off control method, and the method comprises the steps: collecting a test voltage signal of a voltage input port of tested equipment; detecting a phase value of the testvoltage signal, and triggering an on-off control instruction if the phase value of a test voltage signal is a target phase value; carrying out the delay output of the on-off control instruction according to voltage signal transmission time and the on-off response time of the tested equipment, wherein the voltage signal transmission time is the time when the test voltage signal is transmitted to the tested equipment from a voltage input port; and controlling the on / off of the tested equipment according to the on-off control instruction of the delay output. According to the invention, the method enables the on / off of the tested equipment to be accurately controlled by the on-off control instruction, solves a problem that the on-off control efficiency is low in the conventional technology, improves the on-off control efficiency of the tested equipment, and guarantees the testing efficiency of the tested equipment. The invention also provides an on-off control system, on-off control equipment, and a testing device.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a switch control method and system, a switch control device and a testing device. Background technique [0002] With the rapid development of electronic technology, the requirements for the quality of electronic equipment are getting higher and higher. Comprehensive testing of the performance of electronic equipment is an important way to ensure the quality of electronic equipment. [0003] Taking the electromagnetic compatibility and power supply characteristic test of electronic equipment as an example, when performing power line transient interference test on the equipment under test, the test standard requires that the switch of the equipment under test can be turned on and off accurately under various typical working conditions, and It can accurately read parameters such as the maximum value of the peak signal amplitude generated by the device under test at the ...
