Problems solved by technology

Container technology is often based on the LINUX operating system, and the power line carrier port is a serial device under the operating system, which only supports one application APP to open the port. For example, multi-function instruments, phase change switches, electric energy meters, low-voltage intelligent circuit breakers, etc. in the station area cannot be connected through carrier communication.
In view of the above technical status quo, the current smart terminals / smart distribution transformer terminals in the station usually design a complex protocol and a collection APP responsible for carrier management to meet the data requirements of various application APPs, which makes the development of the collection APP difficult and responsible for maintenance. , long stable period, difficult to expand, affecting the access capability and effectiveness of smart distribution terminal / intelligent fusion terminal equipment in the station area

Abstract

The invention relates to a method and a device for sharing a carrier channel by an APP of an intelligent terminal in a station area. In the case of power line carrier communication in a low-voltage power distribution station area, a carrier communication agent APP is equipped to realize the sharing of a carrier channel by each collection APP of the intelligent terminal in the station area. The MQTT protocol bus realizes the transmission of messages, which can be used for intelligent distribution and transformation terminals, intelligent fusion terminals in the station area, concentrators and other equipment, realizes the sharing and interaction of the carrier signal channel of each device, and improves the resource utilization rate of the terminal's power line carrier communication interface. .

Description

technical field [0001] The invention relates to the technical field of power line carrier communication in low-voltage distribution station areas, and in particular to a method and device for sharing a carrier channel by an intelligent terminal APP in a station area. Background technique [0002] Since 2017, the State Grid and China Southern Power Grid have been facing the distribution low-voltage station area. In addition to the monitoring of traditional electrical parameters, such as distribution transformer monitoring, environmental monitoring, residual current action protector monitoring, etc., they are also improving power supply reliability and reducing power outages. There is an urgent need to improve the service capacity of electricity consumption and strengthen the lean management of low-voltage distribution networks; at the same time, with the changes in the external electricity environment such as "electric energy replacement" projects, the increase in the number o...
