Methods for matching and debugging signals in tire pressure monitoring system

Abstract

The invention discloses a method for matching signals, which is used for matching signals between a central monitor in a tire pressure monitoring system and at least one sensing transmitter and comprises the following: a step of acquisition: transmitting inducing signals one by one aiming at each sensing transmitter to induce the sensing transmitter to transmit a real-time signal to the central monitor, and capturing the real-time signal and storing identity code of the sensing transmitter contained in the real-time signal; and a step of matching: generating a learning signal containing the captured identity code, and transmitting the learning signal to the central monitor for learning and storage so as to finish the matching between the sensing transmitter and the central monitor. The methods provide a novel signal matching plan for the tire pressure monitoring system so that an operator is not necessary to perform a plurality of come-and-go operations between a cab and a tire, the complexity of signal matching is simplified, and the signal matching process becomes easier. The invention also relates to a method for debugging the signal matching.

Description

【Technical field】 [0001] The present invention relates to a tire pressure monitoring system (TPMS), in particular, to signal matching between a sensor transmitter mounted on a tire and a function controller mounted on a vehicle body to establish communication between them Basic signal matching methods and corresponding debugging methods. 【technical background】 [0002] TPMS, the abbreviation of Tire Pressure Monitoring System, translated as Tire Pressure Monitoring System, is used to monitor the main parameters such as the pressure and temperature of vehicle tires in real time, so as to ensure that the pressure and temperature of tires are maintained within the standard range and reduce the The probability of blown tires and destroyed tires can reduce fuel consumption and the damage rate of vehicle components. [0003] TPMS includes multiple high-sensitivity sensor transmitters installed on each tire, real-time monitoring of tire pressure, temperature and other data when dr...

Problems solved by technology

This method has the following problems: when the central monitor is adjusted in the cab to enter the learning mode, the operator needs to run out of the cab, and then install the sensor transmitter on the valve of the tire to inflate and deflate to induce To send the learning signal, wait for the central monitor to receive the learning signal. After the sensor transmitter is paired successfully, enter the cab and adjust the central monitor to enter the learning mode to pair with another sensor transmitter. The debugger will undoubtedly run back and forth. too much trouble

The defect brought by this method is: in the same batch of sensor transmitters, there cannot be more than two sensor transmitters with the same last 3-digit ID code, which will bring trouble to the factory production, and there is also a central monitoring Potential for sensors to mislearn from other on-vehicle sensor transmitters

However, this method still cannot overcome the problem that the last three digits of the ID codes of different sensor transmitters are the same. Although the recognition rate is improved, it undoubtedly increases the complexity of the operation.

[0012] In addition, all the above methods are not suitable for the maintenance of tires during use, that is, when they are installed on the car, and can only be relatively suitable for the initial installation of tires. Therefore, they still cannot provide convenience for the regular maintenance of TPMS

Due to the defects of the above-mentioned technologies, the specialization of TPMS is required, and it cannot be maintained and installed in a popular way. For example, when the user purchases new tires and installs them, the matching between the sensor transmitter and the central monitor must be performed after the tires are installed.
