Cell dual-power operation mode detection device and working method thereof

Abstract

The invention provides a cell dual-power-supply operation mode detection device and a working method thereof, and belongs to the technical field of power distribution network automatic data communication. The cell dual-power supply operation mode detection device comprises a power supply circuit, a carrier interface circuit, a narrowband carrier communication module, an RS232 communication interface circuit, an RS485 communication interface circuit, an information control MCU circuit, a power supply circuit for controlling an MCU, a channel indication circuit, a download operation mode selection circuit for controlling the MCU and other circuit parts. Signals are coupled into a 110kV high-voltage line in a capacitive coupling mode, the problem that when electronic device is connected intohigh-voltage power, the equipment is prone to being burnt is solved, and meanwhile potential safety hazards brought to the high-voltage line are avoided. Signal transmission is carried out in a carrier mode, an original networking line structure is not changed, an existing overhead line is adopted as a communication medium, cost is reduced, operation is easy and convenient, and high popularizationvalue is achieved.

Description

technical field [0001] The invention belongs to the technical field of distribution network automation data communication, and specifically relates to a device for detecting the operation mode of dual power sources in a residential area and a working method thereof. Background technique [0002] For the power supply system of a dual-power supply community, since the two power sources come from different power supply lines, a large number of communities may use a certain line for power supply at the same time, causing this power supply line to have a large power supply load pressure, while the other power supply line users Less, the load is lower, which results in unbalanced power supply load. Therefore, it is very necessary to monitor the operating line of the community power supply system and the voltage load of the line at any time. Knowing which users are on each operating line in a timely manner, as well as the actual voltage and power load of each user, is of great sig...
