Application Of WSN Technology In Central Air Conditioning

The central air conditioner is essential in modern life, with the development ofmodern architectural design change rapidly, people hope for the central airconditioning to provide a comfortable environment of increased demand for spaceapplication, the index of Application in the densely populated space in impro vingconstantly. Flexible temperature regulation function as the application of central airconditioning equipment evaluation index, and how to collect the temperature moreprecise has become one of the objectives for improvement. Further development ofthe Internet of things technology,the continuous innovation of wireless sensornetwork technology, which makes the temperature acquisition forms becomemore flexible and reliable.This paper introduces the technology characteristics of WSN(Wireless SensorNetwork), including the standard of wireless sensor network and wireless sensornetwork nodes, the principle and application of Zigbee technology, analyzed theZigbee network technology and network topology structure, then introduces theprinciple of Zigbee communication and Zigbee protocol framework, introduces thespecification of layers in Zigbee protocol, mainly analyzes the TI-Zstack protocolframework.This paper used the CC2530chip system by TI,in the hardware facilities. Whenenhance the network nodes, which can also save the total cost of the material, Thispaper used the CC2530chip system by TI in the hardware facilities at the sametime.According to the characteristics of WSN node has small memory, come up to akind of solution which binding the CC2530and the Z-stack protocol stack systemand temperature acquisition method with DS18B20temperature sensor. This solutioncan be implemented in building space which used central air-conditioning.
