Abstract

The invention discloses a slow frequency-hopping communication experiment system of an industrial multi-hop link. The system comprises an industrial wireless multi-hop communication link, a serial port / ZigBee gateway and a monitoring host, wherein the industrial wireless multi-hop communication link comprises a plurality of communication nodes having a slow frequency-hopping communication function, each of the communication nodes is provided with an experimental antenna and a monitoring antenna, and the monitoring host is connected with the serial port / ZigBee gateway through a serial port. According to the system, dual antennas are arranged on the communication portion, communication nodes are provided with an experimental antenna system and a monitoring antenna system, and the experimental antenna system and the monitoring antenna system are separated from each other and are used for link experiment communication and gateway communication respectively, so that the experiment monitoring and the statistic analysis process do not occupy link communication resources basically, and the simulation performance of the experiment process is guaranteed; and a monitoring computer system monitors and sets each of the communication nodes through wireless communication, so that the experiment system is good in deployment flexibility and expandability and has application and popularization values.

Description

technical field [0001] The invention relates to a communication experiment system, in particular to an experiment system for industrial multi-hop link slow frequency hopping communication. Background technique [0002] In large-scale industrial production, process equipment is dense, and wireless communication is difficult to ensure line-of-sight transmission channels. Field instruments generally need to communicate and network in a multi-hop manner. On the other hand, at present, industrial wireless communication generally adopts multi-channel communication, such as wireless HART, SP100, etc., all use 16 channels, and the slow frequency hopping technology is used in the communication process, that is, it automatically switches to a new channel when the current channel is interfered communication. In this case, industrial wireless communication is often a multi-hop and slow frequency hopping process, which often involves complex processes such as time scheduling, channel al...
