Intelligent scheduling device suitable for carrier communication of ring distribution network and method therefor

Abstract

The invention discloses an intelligent scheduling device suitable for carrier communication of a ring distribution network and a method therefor. The intelligent scheduling device is arranged in the ring distribution network, and comprises a microprocessor module, as well as an Ethernet interface module, a synchronous dynamic random access memory, a flash memory and two serial interface modules, which are respectively connected with the microprocessor module. The intelligent scheduling device further comprises a power supply module for supplying power to the above modules. In the invention, the characteristic that the carrier communication links of the ring distribution network are the same in a ring manner is fully utilized, and the MCU (Microprogrammed Control Unit) microprocessor module is used for control, so as to monitor the communication state of two carrier networks of the ring distribution networks in real time, when some point fails to work, the one with interrupted communication is automatically switched to the other carrier network from carrier equipment, and when the failure of the point is removed, the original carrier lattice structure is restored. According to the invention, full-automatic switching and scheduling of carrier communication are achieved without the need of manual intervention, and the scheduling is carried out in real time without influencing normal carrier communication.

Description

technical field [0001] The present invention relates to a ring-type distribution network carrier communication system and a method thereof, in particular to an intelligent dispatching device and a dispatching method suitable for ring-type distribution network carrier communication that can automatically test and select power line carrier communication links . Background technique [0002] Power line data communication technology (PLC) is a communication technology that uses medium and low-voltage distribution networks as a communication medium to realize the transmission of comprehensive services such as data, voice, and images. It can not only be used as an effective means to solve the "last 1km" of broadband access , and can provide a high-speed data transmission platform for power load monitoring, remote meter reading, power distribution automation, demand side management, enterprise internal network, smart home and digital community. According to the national standard, ...
