The real-time synchronization display system 9. low power-consumption intelligent according to claim 8 is handled official business, which is characterized in that the pressure passes Sensor uses resistance-type diaphragm pressure sensor, model FSR406;The model SHT11 of the Temperature Humidity Sensor;It is described Zigbee wireless communication modules use the CC2650 chips of TI companies, and communication mode uses Zigbee communication agreement;The STM32 Microcontroller uses the low-power chip of model STM32L151RCT6.
  10. 10. a kind of method of work of low power-consumption intelligent office real-time synchronization display system as described in claim 1-9 is any, It is characterized in that, step is as follows:
    1)Pressure sensor gathers pressure signal and the pressure signal of acquisition is sent to voltage comparator circuit;
    2)Voltage comparator circuit handles the pressure signal of acquisition, and determines whether high level, if so, carrying out down One step, otherwise, return to step 1);
    3)First wireless communication module wakes up temperature and humidity sensing after the high level signal that voltage comparator circuit is sent is received Device, and control Temperature Humidity Sensor intermittence gathered data;
    4)Temperature Humidity Sensor collecting temperature data and humidity data, and pass through the first wireless communication module and the second wireless telecommunications The cooperation of module gives the data sending of acquisition to STM32 mainboards;
    5)STM32 mainboards judge the situation on duty of office worker according to the data of acquisition, and will determine that result is sent respectively to electricity Resistive touch screen and liquid crystal display carry out office worker's situation on duty by resistive touch screen and liquid crystal display real-time Display.
