[Abstract]:WSNs is regarded as one of the most promising technologies in this century. It is a combination of wireless communication technology, wireless sensor technology, microelectronics technology, computer language and other technologies. With its advanced concept and broad application prospect, wireless sensor network has been highly concerned by all walks of life. Wireless sensor network has the advantages of small size, low cost and flexible networking, so it is widely used in military, disaster rescue, ecological monitoring, medical treatment, etc. Intelligent transportation has been widely used. With the development of wireless sensor networks, its application field will be more extensive. By collecting signals from wireless sensor nodes, monitoring the deployment field, the routing process is eliminated. It reduces the limit of sensor range in monitoring area, and makes sensor network can be used in various fields flexibly. At present, The main network communication protocols used in wireless sensor networks are ZigBeen WiFiUWB and Bluetooth. Compared with other wireless communication technologies, ZigBee technology has the most obvious advantages, such as low power consumption, ad hoc network and low cost. It has become the preferred communication protocol to receive and receive information between nodes with the lowest power consumption. This paper first introduces the research background and significance of the subject, and then summarizes the development, current situation, structure and characteristics of wireless sensor networks. The technical background of ZigBee and the structure of ZigBee protocol are discussed. This paper grasps the technical advantage of ZigBee and regards it as the core technology of wireless sensor network. Then the frame design of coal mining machinery monitoring system based on CC2530 is put forward. This paper introduces a frame design scheme of wireless sensor network node for vibration monitoring, and designs the hardware of the node. Through the IAR Embedded Workbench platform, the software applied to vibration monitoring of coal mining machinery is designed, and the software is debugged. The problems of data acquisition, processing and receiving and sending of wireless sensor network nodes are successfully solved, and the interconnection of nodes can be realized. Through testing, it is found that the system can basically achieve the expected goal. Finally, the previous work is summarized. At the same time, the shortcomings of the system are put forward, and the development prospect of wireless sensor network in real time monitoring system is prospected.
