Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figure 3-5 As shown, the calibration device for preventing data collision of the TPMS transmitter includes a housing, a time interval setting button 10, an LCD display 11, a calibration start key 12, a transmitter excitation line interface 13, and a processor 14; Processor 14, the surface of the housing is provided with an LCD display 11 connected to the processor 14, a time interval setting button 10, a calibration start button 12, a transmitter excitation line interface 13 and a power interface.

[0027] After the production of each set of TPMS transmitter circuit boards is completed and before potting, the calibration device is used to trigger the TPMS transmitters at equal time intervals, so as to set the launch time reference of the set of TPMS transmitters.

[0028] In the following, a set of TPMS system includes 4 transmitters, a...

Abstract

The invention discloses a calibration device for preventing data collision of a tire pressure monitoring system (TPMS) emitter. The calibration device comprises a shell, wherein a processor is arranged in the shell; a display screen, a time interval setting key, a start calibration key, an emitter excitation wire interface and a power interface, which are connected with the processor are arranged on the surface of the shell. The invention also discloses a calibration method using the device. According to the calibration device, on the basis that the hardware cost of the TPMS emitter is not increased, the emission time references and the fixed time intervals of multiple emitters are set through the calibration device, so that the problem of data conflict or collision of the emitters is completely solved; the time interval of receiving updated display data by that a receiver is fixed, so that a good user experience is achieved.

Description

technical field [0001] The invention relates to the technology of a tire temperature tire pressure monitoring system (TPMS) transmitter, in particular to a calibration device and a calibration method for preventing data collision of the TPMS transmitter. Background technique [0002] At present, TPMS products, as active safety defense devices for automobiles, have a large market demand. The China Automotive Research Institute formulated the TPMS standard in 2009, and the mandatory installation standards for cars are also under study. Each set of TPMS includes a receiver and multiple transmitters (for the convenience of description, 4 transmitters are used as an example below), each transmitter has its own unique ID tag ID, and each transmitter negatively detects the corresponding When the air pressure and temperature in the tire are abnormal, the receiver will send out an alarm to remind the driver to avoid traffic accidents. [0003] When in use, install the 4 transmitter...
