Abstract

The invention discloses a TPMS performance test system and a TPMS performance test method. The system comprises a PC having a first USB interface, a second USB interface, a third USB interface and a series port interface, a receiver / repeater of which a downloading interface is connected with the first USB interface, an attenuator which is connected with the second USB interface and can dynamically adjust the attenuation multiple, a sensor ID scanner which is connected with the third USB interface and is used for scanning an ID bar code of a TPMS sensor and sending the ID bar code information to the PC, and a sensor simulator which is connected with a series port, wherein the sensor simulator simulates the TPMS sensor, receives test data of the PC through the series port and transmits radio frequency signals to the receiver / repeater. Through the system and the method, TPMS receiver / repeater software burning and function / performance tests can be automatically realized, operation is simple, test efficiency is high, and radio frequency indexes of the receiver / repeater can be further calibrated.

Description

technical field [0001] The invention belongs to the field of automotive electronic TPMS, in particular to a performance testing system and testing method for TPMS receivers and repeaters. Background technique [0002] With the continuous development and progress of the automobile industry, TPMS (tire pressure detection) has attracted more and more attention from people, and has more and more applications in automobiles. With the extensive use of TPMS products in real life, the importance of developing large-scale TPMS production line detection systems has become increasingly prominent. [0003] TPMS is divided into several modules: sensors, receivers, and repeaters (truck and bus systems). The production line test methods for receivers and repeaters have not yet been proposed or remain in the laboratory stage, which is a severe challenge for large-scale TPMS product testing. challenge. Contents of the invention [0004] The purpose of the present invention is to provide ...
