1. INTRODUCTIONOFTPMS
TPMS is the shortened form of tyre pressure monitoring system.
TPMS is the active safety system of vehicle. It is used for real-time
monitoring tyre pressure and tyre temperature and transmitting the
information of tyre to driver timely and accurately. TPMS can reduce the
risk of tyre blowing and damaging resulted from low pressure, high
pressure, and high temperature and leaking. Thus protect effectively the
life and property of drivers and passengers.
TPMS display can be installed directly in air-conditioning vent in cab.
It can be also installed in other suitable position through mushroom
stick. The four sensors are installed inside tyre respectively.
When the vehicle starts and its speed is higher than 20km/h, the
sensors installed inside tyre can real time collect the tyre pressure, tyre
temperature and so on. Then the information is transmitted by radio to
TPMS display. TPMS display displays corresponding information after it
receives the wireless signal and alarms when the tyre is abnormal.
