Abstract

The invention discloses a remote control area network (CAN) bus communication system and an implementation method thereof. The system comprises a centralizing unit mounted in a substation or a ring main unit and a plurality of collecting units which are respectively mounted on a cable tunnel wall, wherein the centralizing unit is respectively connected with each collecting unit through the CAN bus. The state in the cable tunnel can be monitored just by laying one CAN bus. Besides, the problem of terminal resistance matching of the collecting units of the remote CAN bus communication is solved, and the problem that the communication baud rate among the units is inconsistent is solved. The system and method have the characteristics of flexibility and convenience in case of long communication distance.

Description

technical field [0001] The invention relates to a power communication system, in particular to a long-distance CAN bus communication system and its realization method. Background technique [0002] With the accelerated development of cities, the rapid growth of power tunnels, and the sharp increase in power loads, how to avoid operational safety accidents caused by overloading and overheating of cables in tunnels, water accumulation in tunnels, toxic gases, etc. affect the safety of power supply systems , It is necessary to adopt modern technical means to improve the operation and maintenance level of power tunnels and tube wells. [0003] The cable operation management department invests a lot of manpower and material resources every year to inspect the environment inside the cable tunnel and the operation status of the cable, especially in the season of high temperature and heavy load. , the anti-theft or damage inspection of the tunnel manhole cover, as well as the heigh...
