Example Embodiment

[0016] Example 1

[0017] This embodiment is suitable for the free routing scheduling method of cable ring network carrier communication, such as image 3 As shown, the hardware includes: the power distribution master station platform and the communication management machine connected in sequence. Two communication ports are preset on the dispatch platform. The port numbers are assumed to be 952 and 953 respectively, corresponding to the No. 1 main carrier and No. 2 main carrier respectively. The No. 1 main carrier machine is connected to the com1 of the communication management machine, the No. 2 main carrier machine is connected to the com2 of the communication management machine, and the slave carrier machine 1, the slave carrier machine 2, and the No. 1 main carrier machine are in the same carrier communication network. From the carrier machine 3, the slave carrier machine 4, the slave carrier machine 5, and the slave carrier machine 6 in the same carrier communication networ...

Abstract

The invention discloses a free routing scheduling method suitable for cable ring network carrier communication. The method comprises the following steps that: any slave carrier machine can communicate with a No.1 master carrier machine and a No.2 master carrier machine; carrier communication management equipment polls two carrier communication networks at intervals; the slave carrier machine compares the signal intensity of carrier signals from the No.1 master carrier machine and the No.2 master carrier machine respectively, and transmits a state data packet to the master carrier machine withstronger signals; the No.1 master carrier machine and the No.2 master carrier machine respectively transmit a serial number of the slave carrier machine corresponding to the received state data packet to a distribution master station platform; the distribution master station platform brings the received serial number of the slave carrier machine into a slave carrier address list corresponding to a corresponding master carrier machine; and the No.1 master carrier machine and the No.2 master carrier machine respectively perform distribution automated data exchange with the slave carrier machinein the respective slave carrier address list. The method utilizes the characteristic that a cable ring network carrier has communication link cyclization, updates a slave carrier address list from time to time in a polling way, and realizes free routing.

Description

technical field [0001] The invention relates to a free routing scheduling method suitable for cable ring network carrier communication, and belongs to the technical field of power line carrier communication. Background technique [0002] At present, the communication needs of the 10KV ring network cabinet power distribution automation system are mainly solved by optical fiber communication, but most of the 10KV ring network cabinets do not have a low-voltage 220V power supply, and due to the wide variety of ring network cabinets, the task of excavating and laying optical fibers is heavy. Complexity and other factors have brought great difficulties to the communication of the 10KV ring main unit power distribution automation system. [0003] Power line carrier communication can be used to better complete the distribution automation communication tasks of ring network cabinets. Power line carrier communication technology (PLC) is a communication medium that uses medium and low...
