The Application Of Monitoring System Based On Internet Of Things

The Internet of Things is on the basis of the Internet and the extension of the network, through wired or wireless communication network, data transmission, the client application can be extended to any goods and goods exchange of information between. This paper to networking perception layer control system based, wired or wireless communication network for information transmission medium the sensing layer control system of unified management, by the coordinator achieve integration and Internet data, thus completing the design of monitoring system of Internet of things. And the networking monitoring system application in hotel fresh air machine control system, to verify the reliability of the monitoring system of Internet of things. The main research work of this paper is:Firstly, according to the application of the Internet of things monitoring system, determine the overall scheme of the monitoring system design, including the control of communication nodes, the network communication and the coordinator.Secondly, complete the hardware design of the node and coordinator, meet the application requirements of the Internet of things.Thirdly, solve the problem of network communication and determine the network’s network plan. Chose the radio frequency chip SI4432 as the carrier of wireless network data transceiver, and it has strong ability of penetration, diffraction and transmission long distance. What’s more, determine the protocol stack of wireless network, and analyze the communication layer, networking, routing, etc. At the same time, the BEB algorithm is optimized to improve the competition fairness of communication nodes.Fourthly, solve the communication problem of the gateway, and realize the protocol conversion between the communication network and the Ethernet. The coordinator uses the Linux system as software platform, and transplant Linux system into it. Moreover, program driver software, and the preparation of the TCP/IP protocol to the coordinator as a server for the client to visit the coordinator.Finally, the Internet of things is applied to the control system of the hotel, and the control system of the fresh air machine is tested, the transmission and the monitoring interface of the host computer are displayed in real time. The network test includes network testing, network testing, network node back to establish the coordinator, including the transmission test on the baud rate, transmission distance test.Through the analysis of the application of the air blower control system, the monitoring system of the Internet of things has realized the data collection, communication network and the normal operation of the coordinator, and has played a good performance in the multi floor and multi obstacle transmission. Moreover, it chieves the desired objectives, It has higher useful value.
