Method for controlling remote communication of intelligent electric power terminal as well as module and terminal

Abstract

The invention discloses a method for controlling the remote communication of an intelligent electric power terminal as well as a module and a terminal. The method comprises the following steps: automatically detecting, by an embedded communication module, the intensity of various communication signals such as satellite communication signals, GPRS, 3G and 4G wireless communication signals and the like, judging whether the preferred signal intensity satisfies a preferred communication threshold value condition or receiving a control instruction, selecting a specific signal as the preferred signal, and completing the electric power transmission and data transmission of a power distribution network intelligent field station devices and terminals. An embedded hot-plug communication module of another embodiment integrates a Beidou circuit and a GPRS circuit, two or more signals can be received simultaneously, the electric power measurement in remote areas and signal instable regions and theacquisition and communication of a power distribution management signal can be realized. In the case of automatically detecting and preferring an economical tariff channel, an economical tariff channel can be used for a power supply enterprise to select.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling remote communication of an electric power intelligent terminal, a module and a terminal. Background technique [0002] The concentrator is the key equipment in the centralized meter reading system. It has the type specification for concentrators in the power industry "Q / GDW1375.22013 Type Specification for Power User Information Collection System Part 2: Type Specification for Concentrators". According to the requirements of the type specification for concentrators, The concentrator adopts a modular design, generally including a display part, a local communication module and a remote communication module. The display part is fixed, and both the local communication module and the remote communication module can be replaced. The local communication module and the remote communication module can directly change the communication by replacing the commun...

Problems solved by technology

The remote communication module adopts an external RDSS terminal, which will cause electromagnetic compatibility technical problems due to the connection of power supply cables, network cables and transmission cables, resulting in interference and instability of meter reading signals

Using external RDSS terminals to upload metering data also has many problems. For example, there are many interactive signals between the concentrator and external RDSS terminals, and the mutual interference is relatively large, and electromagnetic compatibility is difficult; external RDSS terminals The power consumption is relatively large, and the interface power supply of the remote communication module of the concentrator cannot be used directly. Only the 220V power supply input by the concentrator can be used, which has power safety problems, and causes energy consumption of the public power consumption part, resulting in partial distortion of circuit data

[0005] In view of the shortcomings of the external RDSS terminal, the existing technology has the application of the embedded communication module on the concentrator. With the application of the embedded communication module on the concentrator, the remote communication mode involved in the interface of the remote communication module is generally Adopt single-mode communication, that is, the concentrator uses a mobile communication system to communicate with the outside based on the embedded communication module fixed on the remote communication interface, such as using a single GPRS communication mode, Beidou communication mode, and other mobile communication modes, but how? The application of multi-mode communication coexistence on the concentrator needs further in-depth research
