A power grid metering automation terminal system and communication positioning method

Abstract

The invention discloses a power grid metering automation terminal system and a communication positioning method, wherein the power grid metering automation terminal system includes: a metering automation terminal device and a communication module, and the metering automation terminal device communicates with an interface module of the communication module through a transmission line connect. The communication module is equipped with a private network communication unit and a public network communication unit, which can realize automatic and accurate positioning of the metering automation terminal system without affecting the uploading and communication of power grid metering data.

Description

technical field [0001] The invention relates to the technical field of grid data automation, in particular to a grid metering automation terminal system and a communication positioning method for the metering automation terminal. Background technique [0002] The main function of the power grid metering automation terminal is to collect metering data, which includes load management terminals, distribution transformer monitoring metering terminals, low-voltage centralized reading equipment, power station power collection terminals, and electricity sales management devices. After the measurement automation terminal collects the measurement data, it needs to be uploaded to the measurement automation master station by the built-in communication module through the electric power private network. With the power grid company's increasing demand for metering automation terminal management, the location information of metering terminals and SIM cards must be clear, so as to avoid the...

Problems solved by technology

[0003] The existing metering automation terminals basically use GPS global positioning technology for positioning. However, GPS global positioning technology is not suitable for application in metering automation systems due to the requirement that the devices that need positioning must be installed outdoors or equipped with outdoor antennas, and the cost is high.

At present, the commonly used method is to manually enter the "administrative area code" and "terminal address" to mark each metering automation terminal, but this marking method makes the actual physical location of the device not directly related to the content of the mark, which leads to effective positioning. less reliable
