Embodiment Construction

[0026] The present invention consists of two parts, a tire module and a vehicle body module.

[0027] The tire module is mainly composed of tire pressure, temperature, acceleration sensors and a microcontroller containing a radio frequency transmission chip.

[0028] The microcontroller is the "brain" of the tire module and directly determines the behavior of the tire module.

[0029] First, the microcontroller needs to determine whether the running state of the vehicle is running or stopping, so as to determine whether the working mode of the tire module is normal mode or power saving mode. When it is known that the vehicle is in a running state, the microcontroller needs to determine whether the vehicle is stopped; when it is known that the vehicle is in a stopped state, the microcontroller needs to determine whether the vehicle is started, so as to update the current running state of the vehicle. The microcontroller completes this judgment by operating the acceleration sen...

Abstract

The real-time tyre pressure monitoring system includes tyre module and vehicle body module. The tyre module includes one acceleration sensor for detecting centrifugal force of the tyre for accurate measurement of the centrifugal force to estimate the vehicle speed and state, and the tyre module operates in economizing mode when the vehicle stops, in normal mode when the vehicle runs and in alarm mode with relatively high power consumption when the pressure or temperature changes abruptly. The tyre module adopts virtual conflict retreating algorithm to obtain relatively high emitting success rate at lower emitting power. The user can inquire the pressure and temperature in near stage of the tyres. The present invention is one low power consumption real-time tyre pressure monitoring system.

Description

technical field [0001] The invention relates to a tire pressure real-time monitoring system with low power consumption. Background technique [0002] During the high-speed driving of the vehicle, tire failure is the most worrying and most difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. The tire pressure monitoring system (TPMS, Tire Pressure Monitoring System) is used to automatically monitor the temperature and pressure inside the tire in real time when the vehicle is running, and to alarm the tire leak and low air pressure to ensure driving safety. [0003] According to different monitoring methods, tire pressure monitoring systems are mainly divided into two types: [0004] (1) Indirect tire pressure monitoring system (Wheel-Speed ​​Based TPMS) [0005] The indirect tire pressure monitoring system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between...
