Abstract:

In the traditional switching control of the signal source of the communication transmission equipment in the Internet of things, the problem of the large error of switching control is easy to be caused by the problem of packet loss. A multi-band remote switching control technology based on node monitoring is proposed. By analyzing the communication transmission equipment of the Internet of things, a signal control framework is proposed to monitor the switching node of the multi-band signal source of the device. According to the monitoring results of the nodes, the problem nodes in the multi-frequency signal source remote switching are found, and the location of the problem signal nodes is determined by setting the dynamic threshold. On the basis of dynamic control mechanism and packet loss calculation formula, the problem of large control error caused by packet loss is solved. Title Netflow data exchange method is used to control the remote switching of the signal source at the location node. The experimental results show that the control error of this method is 0.71 less than that of the traditional method, and the control effect of remote switching of signal source can be improved.
