GPRS communication based LIN bus automatic remote testing device and testing method

Abstract

The invention discloses a GPRS communication based LIN bus automatic remote testing device and testing method. The automatic testing device comprises a remote control end with a short message sending and receiving module, wherein remote detection devices are connected to the remote control end; a display is arranged at the remote control end; each remote detection device comprises a GPRS communication module which is connected with an LIN bus communication module, and the LIN bus communication module is connected with an indication module and is connected with an LIN bus communication product to be tested through an LIN bus; the remote control end sends a mobile short message containing a testing command to each remote detection device; each remote detection device sends the testing command to the corresponding LIN bus communication product to be tested through the corresponding LIN bus communication module; each LIN bus communication module receives testing information which is sent back from the corresponding LIN bus communication product to be tested, and sends the testing information to the remote control end through the corresponding GPRS communication module. The testing device and testing method provided by the invention achieve remote testing, and have the advantages of higher convenience, less labor consumption, high convenience in operation, and high stability.

Description

technical field [0001] The invention relates to automotive electronics, in particular to a LIN bus remote automatic testing device and testing method based on GPRS communication. Background technique [0002] In automotive electronics, LIN bus is a communication bus standard widely used in the industry. The LIN bus is a half-duplex serial communication standard. Because of its simple protocol and strong anti-interference, it is used by many automobile manufacturers. The LIN bus communication products matched with LIN bus are also widely used in automobiles. In the production process of LIN bus communication products, the LIN bus communication It is very important to test the function and stability of the product. [0003] Existing LIN bus tests are local tests performed through serial ports or USB ports. If the product breaks down in other places, the equipment cannot be brought to the site, making fault diagnosis difficult. Finding a more reasonable, more efficient, and ...
