Power distribution network downlink equipment management device and method based on CAN bus

Abstract

The invention relates to a power distribution network downlink equipment management device based on a CAN bus. The device comprises a downlink equipment management APP, a standard communication protocol, a control processor, an uplink interface and a downlink interface, wherein the downlink interface comprises but is not limited to a CAN port, downlink equipment of a power distribution network isconnected through the CAN port, plug and play of the downlink equipment is realized through a downlink equipment management APP and a standard communication protocol, and the control processor is physically connected with the uplink interface and the downlink interface; the control processor is a dual-core processor, supports a container technology and at least supports four containers; and APPs are deployed in the containers, and the containers and the APPs can communicate with one another through data buses or shared memories. According to the invention, unified management of access of the CAN interface to downlink equipment can be realized; a plug-and-play function of downlink equipment is realized; the device has a data management function, achieves the unified distribution of data, unifies the communication protocol of downlink equipment of a power distribution network, and achieves the unified management of the access of the downlink equipment.

Description

technical field [0001] The invention belongs to the technical field of distribution networks in the electric power industry, and in particular relates to a device and method for managing downstream equipment of a distribution network based on a CAN bus. Background technique [0002] At present, the field of distribution network is developing rapidly, and more and more devices are connected to the distribution network. However, the communication protocols of the connected devices are not unified, showing a variety of characteristics. As a result, the terminal equipment of the distribution network has a large workload for protocol processing. For different communication equipment, it is necessary to develop corresponding software function modules and upgrade system programs. For downlink terminal devices that support APP installation, when multiple APPs access different peripherals through the same interface, there will be conflicts in port control rights, resulting in communi...
