Embodiment 1

[0028] The invention provides a dual-mode communication intelligent electric energy meter, which includes: an MCU control module, a switching power supply module and an external communication module.

[0029] A switching power supply module is a power board that includes a built-in communication module.

[0030] The built-in communication module and the external communication module communicate with the MCU control module through respective corresponding UART (Universal Asynchronous Receiver / Transmitter) serial ports.

[0031] A dual-mode communication smart energy meter provided by the embodiment of the present invention realizes the dual-mode communication of the smart energy meter through two internal and external communication modules, and the two communication modules communicate with the MCU control module through two UART serial ports, avoiding the existing In the technology, the dual-mode module uses the same serial port to cause data congestion at the data interface e...

Embodiment 2

[0042] Embodiment 2 provided by the present invention is an embodiment of a centralized meter reading networking method provided by the present invention. The centralized meter reading networking method is based on a dual-mode communication intelligent electric energy provided by Embodiment 1 of the present invention. Table, the built-in communication module and the external communication module of each dual-mode communication smart energy meter contain the same two communication methods, wherein the first communication method is the same as the communication method of the concentrator, and the method specifically includes:

[0043] Step 1, the concentrator sends a reading communication command to each dual-mode communication smart energy meter in the first communication mode, receives the meter reading data returned by each dual-mode communication smart energy meter, and returns the meter reading data to the concentrator through dual-mode communication The smart energy meter i...

Embodiment 3

[0056] Embodiment 3 provided by the present invention is a specific application embodiment of a centralized meter reading networking method provided by the present invention. The example station area concentrator adopts carrier communication mode, and the dual-mode communication smart energy meter The communication methods are "narrowband carrier + micro-power wireless", such as figure 2 Shown is a schematic diagram of a centralized meter reading network structure provided by the embodiment of the present invention, consisting of figure 2 It can be seen that in the specific networking process:

[0057] The concentrator uses power line carrier communication to send reading communication instructions to each energy meter connected downwards. Some of the energy meters will respond with data after receiving the carrier communication instruction from the concentrator module, while the other part of the energy meters will respond due to the communication distance. , The interfere...

Abstract

The invention belongs to the field of intelligent electricity meter communication, and provides an intelligent bimodule communication electricity meter and a centralized meter reading and networking method. The intelligent bimodule communication electricity meter comprises an MCU control module, a switch power module and an externally arranged communication module; the switch power module adopts a power panel comprising an internally arranged communication module; the internally arranged communication module and the externally arranged communication module are communicated with the MCU control module through two corresponding UART serial ports respectively. Bimodule communication of the intelligent electricity meter is achieved through the internally arranged communication module and the externally arranged communication module, the internally arranged communication module and the externally arranged communication module are communicated with the MCU control module through the corresponding UART serial ports respectively, and therefore the problem that in the prior art, data congestion occurs at the data interface end of the electricity meter due to the fact that the two modules adopt one series port is solved.

Description

technical field [0001] The invention belongs to the field of smart electric energy meter communication, and in particular relates to a dual-mode communication intelligent electric energy meter and a centralized meter reading networking method. Background technique [0002] With the widespread use of smart energy meters, my country has gradually established and improved the electricity information collection system of the power grid. At present, single-mode communication is mainly used for electricity consumption information collection. The mainstream technologies mainly include power line communication and micro-power wireless communication, as well as emerging communication methods such as broadband power line carrier and CDMA. [0003] Power line communication uses the low-voltage power line distribution network for carrier communication. This method does not need to re-establish the network, and the cost is low. However, the power line has many non-ideal factors as a comm...
