At present majority Pressure-Sensor Based TPMS is
a simplex communication system. The paper applies the
technology of low-frequency wake-up to realize the TPMS
bidirectional communication and Low-Power consumption of
the sensor module. In the design of TPMS, the character of
Atmel low frequency communication ATA5283, ATA5275 are
introduced. The corresponding communication system for low
frequency Wake-up are described in detail. Furthermore, the
application in a Tire Pressure Monitoring System (TPMS) is
given; a hardware realization scheme of low frequency
Wake-up is proposed; a relevant software process is designed.
The system processes many advantages in low power and
security.
