Abstract
The utility model relates to an intelligence wireless alarm of the temperature and pressure of the wheels of vehicle. The temperature transducer transforms the nocturnal radiation and environment temperature of the inner wall of the wheel into voltage signals. The air pressure electric transducer converts the pressure of the inner wheel into voltage signals. The above three signals are sent an operational amplifier T L 062 for amplification by electric connection. The amplified signals are then sent into the three A to D ports of a single chip P I C 12 C 672 and are converted into digital quantity by the A to D. The three digital quantity are sent out by a sending module that comprises a surface acoustic wave oscillator N D R4 33 A. Two 3.6 V button cell batteries supply electricity. An eccentric switch is connected on the electricity supply circuit of the electricity power source and the launcher. The signals of each wheel adopt time division multiplexing. The receiver is installed in the driving cab and adopts Micrf 011 demodulator. The demodulated digital signals are sent into a micro processor P I C 16 F 873 for processing and then sent into the LED for light and sound reminding. The utility model controls the pressure transducer of the same vehicle and sends signals with different time intervals so as to reduce cross interferences between the signals of the transducers and improve the receiving effect of the monitor receiver. The utility model adopts low energy consumption single chip and technology, wireless sending technology and the pressure transducer adopts pressure sensitive piece and membrane thermopile. The display of temperature and pressure and other functions are accurate with the precision of better than one percent.
