Design and Implementation of Wireless Temperature Controller Based on Zigbee

Abstract

This paper introduces a design of wireless temperature controller hardware platform based on ZigBee. Wireless temperature controller using ZigBee to build intelligent household heating control system. By CC2530 chip consis the core and related peripheral circuit. Interworking user can realize the information through the mobile comsts of wireless temperature controller hardware platform amunication network, Internet and intelligent household heating control system, Real-time monitoring of heating information home. Index Terms - ZigBee, UC/OS - II, CC2530 , Wireless controller hardware platform I. Introduction During the winter heating period, most of the city in our country use the central heating, and 24 hours a day continuous heating. The heating system consider little about if there are people in the house, everyone has their own require for the room temperature, use cannot real-time ,mobile control the heating equipment, user passive using heating, cannot regulate the room temperature by themselves, heating energy consumption of huge. For saving efficiency, the Ministry of Construction provides residential heating progressive realization of household metering charges. While most of the the present household metering heating system use local control, cannot achieve the real-time, mobile collection information for the heating equipment. The monitoring command cannot mobile, real-time communicated to the heating equipment. Monitoring and control of the heating equipment can not achieve full-duplex mode. In recent years, with the development of communication technology, wireless transmission of information is more and more stable and reliable, its anti-jamming capability, error correction capability and confidentiality growing ability, this makes real-time and mobile control the heating equipment become possible, heating equipment monitoring and control work in full-duplex mode. Based on the ZigBee network in the wireless personal area network, networking, and low - power sensor networks and other fields outstanding performance. The study presents a wireless ZigBee smart mobile controller system of household heating thermostat. The eventual realization users can use intelligent terminal control their own heating device status, achieve single-user control, just pay the actual using heating. Heating unit personnel use web access Heating Information Center query the heating, and achieve remote meter reading. II . Introduction of ZigBee Technology Zigbee is a wireless digital network short distance, low power consumption, high reliability. The ZigBee protocol from bottom to top, respectively, the physical layer (PHY), media access control (MAC) layer, transport layer, network layer (TL) (NWK), the application layer (APL), Provisions of the physical layer and media access control layer following the IEEE 802.15.4 standards. The main characteristics of ZigBee network is of low power consumption, low cost, low rate, support a large number of nodes, supports a variety of network topology, low complexity, fast, reliable, safe. Devices in ZigBee network can be divided into Coordinator (Coordinator), the sink node (Router), the sensor nodes (EndDevice) and other three kinds of roles, ZigBee network as shown in Figure 1.
