e sends an LF low frequency signals, in turn will activate and turn the tire module RF receiver interrupt waiting to receive each module sends back the tire temperature data in real time for the decoded analysis, the standard set safety pressure and temperature range, and determines whether the alarm, and transmit data to the liquid crystal screen display. Set reasonable time delay, the loop above flow timeshare acquisition and monitoring the pressure of the tire module temperature conditions. Thus the fundamental solution to the problem of collisions with the frequency signal interference, but also to save power provides an effective control methods. Fully into account the energy and real-time monitoring of these two factors, the system initiates a set interval 200ms LF wakeup operations.
