Vehicle tire pressure monitoring system based on NFC

Abstract

The invention discloses a vehicle tire pressure monitoring system based on NFC, which belongs to the field of tire pressure monitoring systems. The system comprises a plurality of sensors, a repeaterand a mobile terminal, the sensors are arranged in vehicle tires and acquire vehicle tire data once every 30 seconds and transmit the vehicle tire data to the repeater, the repeater gathers the vehicle tire data collected by the sensors into tire monitoring data and transmits the tire monitoring data to the mobile terminal through a first NFC communication module, a control system and a second NFCcommunication module are arranged in the mobile terminal, the second NFC communication module receives the tire monitoring data and transmits the tire monitoring data to the control system, and the control system comprises a display module, an alarm module and a calibration module, and the calibration module is used for modifying a set parameter range. According to the vehicle tire pressure monitoring system based on NFC, calibration operation is simple, data of all tire pressure sensors can be read at a time, communication is stable, and high-frequency interference is avoided.

Description

technical field [0001] The invention belongs to the field of tire pressure monitoring systems, in particular to a vehicle tire pressure monitoring system based on NFC communication. Background technique [0002] Tire Pressure Monitoring System TPMS (Tire Pressure System) refers to an auxiliary system installed on car tires for real-time monitoring of tire pressure. By installing a transmitter containing a high-sensitivity sensor chip on each wheel, it can be monitored when driving or stationary. , Real-time monitoring of tire pressure, temperature and other data, and transmit to the controller through radio frequency, when the tire leaks or low pressure, it will alarm to ensure driving safety. [0003] In the field of commercial vehicle tire pressure, the number of commercial vehicle tires is several times higher than that of ordinary household passenger vehicles. The position calibration and reading of tire pressure sensors are relatively cumbersome. When the pressure senso...

AI Technical Summary

Problems solved by technology

[0003] In the field of commercial vehicle tire pressure, the number of commercial vehicle tires is several times higher than that of ordinary household passenger vehicles. The position calibration and reading of tire pressure sensors are relatively cumbersome. When the pressure sensor fails, it is difficult for ordinary drivers to calibrate the new sensor by themselves. , requires professional tire pressure calibration tools, which are expensive and cumbersome to operate. Therefore, it is difficult for every driver to purchase and learn to use the calibration tools. They need to go to a specific maintenance point for replacement and calibration, and the process is cumbersome.

In addition, the tires may break down on the way to the maintenance point, but at this time the tire pressure sensor has failed and the driver cannot be notified in time, which is prone to dangerous situations

The existing tire pressure sensor with NFC function is only a product to avoid far-field high-frequency interference, and it is the same as the low-frequency near-field communication function of the sensor itself.
