Abstract:In the process of information monitoring, the information omission of the traditional communication terminal is not considered, which leads to the low precision of the monitoring. The design of information intelligent monitoring system for the communication terminal of IOT based on particle filter is proposed. According to the environmental characteristics of Internet of things, the whole system structure is divided into terminal sensing unit, monitoring switch unit and client unit. The hardware of each component is improved. Particle filter algorithm is used to identify PAN information in coordinator. Intelligent scanning node information are missing, in the limited scan statistics on the missing beacon range, to obtain the corresponding coordinator beacon information, and sends a connection request for re allocation of node address, add connection success status in the new directive address, optimize the software monitoring function, complete system design. The experimental results show that the system can fully process missing information in the nodes, display real-time wavelength stability, and display the results clearly, and effectively improve the monitoring accuracy.
