Automobile skylight durability automatic test system

Abstract

The invention discloses an automobile skylight durability automatic testing system. The system comprises an NI CompactRIO embedded controller, a power supply module, a motor drive and relay module, acurrent sensor, a skylight part, an alarm and a 4G communication module. The NI CompactRIO embedded controller is connected to a current sensor and a voltage sensor which are respectively used for acquiring current and voltage when a skylight working motor works; the alarm is connected to a digital output port of the NI CompactRIO embedded controller; the NI CompactRIO embedded controller is connected to a PC host and a display through the Ethernet to realize data communication; wherein the NI CompactRIO embedded controller is connected to the 4G communication module through an RS232 serial port, the model of the 4G communication module is USR-G770, and the 4G communication module and an APP mobile control terminal realize mobile remote monitoring. A virtual instrument technology is adopted, modular hardware is used, the same hardware overhead is reduced, data of each module is shared through the host, and the measurement speed is increased.

Description

technical field [0001] The invention relates to the technical field of automatic test of durability of automobile sunroof, in particular to an automatic test system of durability of automobile sunroof. Background technique [0002] Smart car components such as car electric sunroofs have been widely used in cars. Sunroofs have become a standard configuration of family cars. Cars basically have a choice of sunroof configuration, small, large, panoramic, panoramic can be opened, all kinds of tricks. The improvement of technology and the increasing attention of consumers to the driving experience have made the penetration rate of car sunroofs in China increase year by year. However, if the skylight is not used properly, it will cause noise, abnormal noise, stop working and other related problems. The performance test of electric sunroof components plays an important role in ensuring the quality of the whole vehicle. In order to ensure the quality of automobile sunroofs is stab...
