Abstract

The invention discloses an interference pulse generator for an automobile power supply system switch, which comprises an interference pulse generation module, a relay, a DC (Direct Current) power supply and a sample switching-in device which are packaged in a chassis. The interference pulse generation module, the DC power supply and the sample switching-in device are respectively and electrically connected with the relay. According to the interference pulse generator for the automobile power supply system switch, which is disclosed by the invention, the product is detected totally according to the international standard, the qualified rate of the finished automobile loading can be greatly improved and the analysis and modification can be carried out according to acquired data so as to correctly evaluate the product at the first time and rise the automobile part technical evaluation by a certain height.

Description

technical field [0001] The invention relates to the field of electronic measuring instruments, in particular to a pulse generator used for testing the anti-interference performance of a switch of an automobile power supply system. Background technique [0002] With the rapid development of the automobile industry, the comfort and safety of the car have been pushed to a relatively strict historical height, which has attracted more and more attention from consumers: the power of the car, how it is handled, fuel consumption and high safety factor Not high, consumers will inquire about the detailed information of the car from various aspects and multiple channels. When encountering the same price and the same configuration, people will regard safety as the ultimate criterion for buying a car. Now many advanced technologies are applied to automobiles, such as airbag detonation, GPS global positioning system, keyless start, DVVT (intake and exhaust dual continuous variable valve ...
