Reliability testing system and method of automobile remote control key

Abstract

The invention discloses a reliability testing system and method of an automobile remote control key. The system comprises a computer, a single chip microcomputer, a switch power source, a voltage adjustable output module and a radio frequency module. The switch power source is connected with and powers the single chip microcomputer and the radio frequency module; the PWM (pulse width modulation) interface of the single chip microcomputer is connected with the control end of the voltage adjustable output module; the input end of the voltage adjustable output module of is connected with the switch power source, and the output end of the voltage adjustable output module is connected with the power end of the a remote control key to be tested; the AD (analog / digital) interface of the single chip microcomputer is connected with the output end of the voltage adjustable output module, and two IO (input / output) interfaces of the single chip microcomputer are connected with the unlocking keying circuit and the locking keying circuit of the remote control key to be tested respectively; a communication interface is connected with the radio frequency module, the radio frequency module is communicated with the remote control key to be tested in a wireless mode; the computer is connected with the single chip microcomputer. The reliability testing system and method of the automobile remoter control key is applicable to the power supply voltage step-down process of the automobile remote control key to test the reliability of code hopping, low-battery warning and minimum working voltage of the remote control key, can reduce the manpower cost and can reduce the possibility of errors.

Description

technical field [0001] The invention belongs to the technical field of automobile detection, and in particular relates to a reliability test system and method for an automobile remote control key. Background technique [0002] As a means of transportation, cars have entered the families of ordinary people. The keys used to open and close the doors have gradually developed from the original mechanical keys to the current remote keys. The biggest advantage of car remote keys is that they do not need to be checked. The lock hole can be unlocked and locked remotely and conveniently. Therefore, the reliability of the car remote control key is very important to the use of the vehicle. In the development stage of the car remote control key, its reliability needs to be tested. [0003] CN 102142912 A discloses a "measuring device for battery life and emission performance of car remote control key and its measurement method", which includes a spectrum analyzer, a cylinder for pressi...

AI Technical Summary

Problems solved by technology

It is used to automatically test the battery life and emission performance of the car remote control key, which can reduce labor costs and reduce the possibility of errors. The reliability of the battery alarm and the minimum operating voltage of the remote control key is tested, and the above test is an important indicator to detect whether the car remote control key is reliable. If manual testing is used, the test is difficult, heavy, inefficient and error-prone.
