Zigbee-based Wireless Heating Network Monitoring System Study

The more we do research for the energy saving of the heat-supply system in the heating and ventilating field, the more we will focus on the heat-supply measurement and temperature control in this field. The heat-supply measurement and temperature control is a hi-tech issue. It is a good example that high technology efficiently apply to implement the policy of country and improve the quality of life. It has a large market space. The research for the present heat-supply monitoring system in Daqing of Heilongjiang province tell us that the present system use the Modem as the communication mode to monitor the system parameter in real time. Some defects occurred during the using of the present system, for example fixing the equipment disturbing the residents and the dividing of the telephone expense and so on. The fact proves that the present system need to be updated.The Zigbee is very low-cost, very low power consumption, two-way, wireless communications standard. On the basic of the research of the existent system in Daqing, we use the wireless communication (GPRS and Zigbee) mode to monitor the parameter such as temperature. Also we leave the interface for the intelligent heat thermometer and the intelligent temperature control valve. The wireless communication mode solves the problem existing in using the Modem. And using the intelligent heat measurement thermometer and the intelligent temperature control valve will solve the opaque problem in the heat-supply measurement. All of these will provide the premise for the heat-supply measurement and temperature control in real time.The thesis introduces the research background and the entire composition of the Remote monitoring system of heat-supply network based on Zigbee and describes the structure and the function of remoter both on hardware and software. The thesis pave the way for the further developing of the applicable heat-supply monitoring system based on Zigbee.
