WSN技術(shù)在集中式空調(diào)中的應(yīng)用
[Abstract]:Central air conditioning must be few in modern life. With the rapid development of modern architectural design, people's demand for central air conditioning to provide comfortable environment has increased, and the index of densely populated space applications is also increasing. The flexible temperature regulation function is regarded as the evaluation index of the application of central air conditioning equipment, and how to carry on the more accurate temperature collection also becomes the improvement target. The in-depth development of Internet of things technology, innovative wireless sensor network technology, which makes the form of temperature acquisition more flexible and reliable. This paper first introduces the technical characteristics of WSN (Wireless Sensor Network, (Wireless Sensor Network), including the wireless sensor network standard and the characteristics of wireless sensor network nodes, the principle and application of Zigbee technology, This paper analyzes the networking technology and various network topologies of Zigbee, and then introduces the principle of Zigbee communication and the framework of Zigbee protocol, briefly introduces the specifications of each layer of Zigbee protocol, and focuses on the analysis of TI-Zstack protocol framework. In this paper, the CC2530 chip system of Texas Instruments is used in the hardware facilities to enhance the network nodes and save the total material cost. In view of the small memory of the WSN nodes, A CC2530 chip system combined with Z-stack protocol stack and a temperature acquisition method of DS18B20 temperature sensor are presented in this paper. This scheme can be implemented in the central air conditioning used in the building space.
