A feeder automation system using can bus communication

Abstract

The invention discloses a feeder automation system adopting CAN bus communication and belongs to the field of communication. According to the feeder automation system adopting CAN bus communication, branch node partition modules and pre-breaking points are set; when the influence of a fault monitored and predicted by a power distribution monitoring module is relatively serious, a heater is used for heating and fusing the pre-breakpoint of a node where the fault is located, and therefore, the fault point and the other normal operation parts of a system are completely isolated, the fault range of the fault point is timely prevented from being continuously expanded, the fault range is effectively controlled to be minimum; and in the above process, a breakpoint sheath bag can be set to gatherheat generated by the heater in the breakpoint sheath bag, so that fusing efficiency can be improved, and on the other hand, the interior and exterior of a double-layer hollow capsule shell are separated, so that the influence of heat in the double-layer hollow capsule shell on other parts on the outer side of the double-layer hollow capsule shell is effectively avoided, and safety during the fusing of the pre-breaking point is improved.

Description

[0001] The invention relates to the field of communication, more specifically, to a feeder automation system using CAN bus communication. Background technique [0002] CAN belongs to the category of field bus, which is a serial communication network that effectively supports distributed control or real-time control. [0003] The feeder, also known as the cable, plays the role of transmitting signals in the cable TV system, through which the signal received by the antenna is transmitted to the front-end system, and the signal output by the front-end is also transmitted to the TV of each user by the cable. Therefore, the quality and model of the feeder are important factors that directly affect the reception effect and signal transmission quality of the cable TV system. [0004] The feeder is the signal line connecting the early TV to the outdoor antenna. It is generally flat and double-wire. The wire body is made of insulating plastic. There is no shielding layer outside, and t...

Problems solved by technology

[0012] Although the existing feeder automation system can realize the closed-loop operation of the distribution network, in case of a fault, it can cut off the fault section instantaneously and maintain uninterrupted power supply to the non-fault area, and is compatible with the open-loop operation mode, but in the actual distribution network, It is very complicated. Although the fault point is cut off by the switch, for more complicated faults, it is only cut off and isolated. If it is not handled in time, the fault will continue to expand and cause greater losses.
