Low-voltage electric power acquisition terminal and electric power data communication method

Abstract

The present invention discloses a low-voltage electric power acquisition terminal. The low-voltage electric power acquisition terminal comprises an acquisition circuit configured to analyze a first connection request from a master station and identify a connection request state control parameter thereof; generating data format description parameter according to the connection request state control parameter; responding to the first connection request according to the generated data format description parameter; receiving an electric power acquisition request from the master station after receiving a determination control parameter from the master station in response to the above request, and establishing a communication connection based on a first communication protocol link; sending a second connection request to an ammeter. The low-voltage electric power acquisition terminal also comprises a communication circuit connected with the acquisition circuit and configured to monitor and receive a first connection request from the master station; sending the second connection request to the ammeter. In one embodiment of the present invention, an electric power data communication method on the basis of the low-voltage electric power acquisition terminal is designed.

Description

technical field [0001] The invention mainly relates to the power collection technology of the power grid system, especially the improvement of the low-voltage power collection terminal commonly used in the power grid system environment and the power data collection and communication method of the power grid system. Background technique [0002] With the rise of the specification DLT698.45 - "Electrical Energy Information Acquisition and Management System-Object-Oriented Interoperability Data Exchange Protocol", the collection terminal equipment and electric meters that support the protocol are gradually applied to the electric power collection site, which brings A field application problem came up: the electric meters installed on site are basically based on the DL / T645-2007 protocol. To support the DLT698.45 protocol, a large number of electric meters need to be replaced. In the case of not replacing the meter, upgrading the original protocol station supporting DL / T645-2007...
