Embodiment Construction

[0009] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0010] see figure 1 , the system includes three parts: wireless sensor, central receiver and display. The wireless sensor is located in the motorcycle tire, detects the tire pressure and temperature data in the motorcycle, and transmits the data to the central receiver through wireless. After the central receiver processes the received signal, it drives the display on the dashboard for display and alarm. The center frequency of system wireless communication is 315MHz / 433MHz.

[0011] The wireless sensor includes MEMS pressure sensor 1 , digital conditioning module 2 , centrifugal switch 6 , low frequency antenna 7 , wireless transmitting module 3 , battery 5 and transmitting antenna 4 . The MEMS pressure sensor 1 is a silicon resistance pressure sensor, and the output of its Wheatstone bridge is a differential voltage signal. The digital conditioning mod...

Abstract

The invention provides a tire pressure monitoring system for motorcycle tires, which essentially comprises a wireless sensor, a central receiver and a display; wherein, the wireless sensor is built-in type. An MEMS pressure sensor, a centrifugal switch and a low-frequency antenna are connected with a numerical signal modulation module; the numerical signal modulation module is connected with a wireless transmitting module; the wireless transmitting module is connected with a transmitting antenna; the central receiver is arranged inside a motorcycle; a receiving antenna is connected with a wireless receiving module; the wireless receiving module is connected with a control module; the control module is connected with a display driving module; the display driving module is connected with the display; the display is integrated in a motorcycle dash board. The system has the advantages of adopting a wireless way to monitor the tire pressure of the tires of the motorcycle in a real-time manner and adopting the MEMS pressure sensor and the centrifugal switch to ensure the tire pressure monitoring system to be reliable, durable, low in energy consumption and long in service life and have the function of display alarm.

Description

technical field [0001] The invention relates to a vehicle tire pressure safety monitoring system, in particular to a tire pressure monitoring system for motorcycle tires. technical background [0002] Tires are an important safety component of motorcycles. During driving, tires have four functions: bearing load, generating driving force and braking force, cushioning, shock absorption, and changing the driving direction. According to the survey, most motorcycles use pneumatic inner tubes. However, when the tire is damaged by foreign objects during driving, a slow leak will occur, resulting in a decrease in tire pressure. Or when the motorcycle is not used for a long time, due to the influence of environment and temperature changes, the tire pressure will also slowly leak. Too low tire pressure will not only increase fuel consumption, but also cause longer braking distance, understeer or even rollover . Therefore, it is very important to monitor the tire pressure of motorcy...
