Wireless monitor system for automobile tire pressure and temperature

Abstract

The invention relates to a wireless monitor system for automobile tire pressure and temperature. The system comprises a transmitting end, a receiving end and a relay end; the system monitors tire pressure, temperature and power supply voltage in real-time via a sensor module at the transmitting end and transmits the information wirelessly to the receiving end, the receiving end displays the transmitted data on a display device, and if the abnormality of the transmitted data is present, the system alarms to remind driver of taking relevant measures; the system can also transmit the received data to a remote control center via a remote transmitting module, thereby facilitating the united scheduling and management of the control center on automobiles, and the system is further provided with the relay end, which increases the transmission distance of data. The ireless monitor system for automobile tire pressure and temperature has the advantage that: the temperature and pressure inside tires of large automobiles such as mine truck and the like can be effectively monitored, and driver can be enabled to be timely aware of the safety information of tires in order to avoid casualties and property loss caused by abnormal tire pressure and temperature as much as possible.

Description

technical field [0001] The invention relates to a monitoring system, mainly a wireless monitoring system against electromagnetic interference, especially a wireless monitoring system for tire pressure and temperature of mining vehicles and large freight vehicles. Background technique [0002] Tire pressure is an important indicator that affects the driving performance and safety performance of the car. If the tire pressure is too high, it will accelerate the wear of the tire and easily cause the crown to burst. At the same time, the friction with the ground will be reduced, which will also affect the braking performance; If the air pressure is too low or the air leaks, the friction with the ground will increase exponentially, which will also accelerate the wear of the tire and increase fuel consumption; since the tire sidewall is the weak part of the tire, when the air pressure is too low, it will be continuously squeezed and stretched, It is easy to cause fatigue failure an...

AI Technical Summary

Problems solved by technology

[0006] 1) The pressure measurement range of the existing tire pressure monitoring system is relatively low and cannot be directly used for tire pressure monitoring of mining vehicles or other large freight vehicles

[0007] 2) The existing tire pressure monitoring system is installed close to the valve, the measured temperature cannot accurately reflect the real temperature inside the car tire, and the installation method is complicated and the cost is high

[0008] 3) The existing tire pressure monitoring system mainly adopts single-vehicle mode, which does not form a network with other vehicles and lacks unified management

[0009] 4) The existing tire pressure monitoring system has poor signal transmission stability, high bit error rate, and short transmission distance in an environment where the wheels are driven by electric wheels and the electromagnetic interference is large, so it is impossible to effectively monitor the pressure and temperature inside the car tires
