Embodiment 1

[0027] See Figure 1-Figure 4 Shown.

[0028] The present invention provides a high-speed meter reading system based on an optical fiber network, which includes a concentrator, an Ethernet passive optical network and an optical fiber electric meter; the concentrator establishes a communication channel with the optical fiber electric meter through the Ethernet passive optical network; The Ethernet passive optical network includes an optical line unit and an optical splitter; the optical fiber meter includes an optical network unit, a microcontroller, and a monitoring unit. Both the optical network unit and the monitoring unit are connected to the microcontroller, and the The optical line unit is connected to the optical splitter through an optical fiber, and the Ethernet interface of the optical fiber meter is connected to the optical splitter. The monitoring unit transmits the fiber-optic electricity meter data to the microprocessor, and the microprocessor transmits the fiber-op...

Embodiment 2

[0036] See Figure 5 with Image 6 Shown.

[0037] The present invention provides a method for high-speed meter reading based on an optical fiber network. The method includes:

[0038] The concentrator establishes a communication channel with the optical fiber power meter through an Ethernet passive optical network.

[0039] The concentrator communicates with the optical fiber electric meter through the communication channel. The concentrator collects or configures the IP address and port of the optical fiber electric meter, and sends meter reading frames to a predetermined number of the optical fiber electric meter at the same time every preset time period.

[0040] It is understandable that the main time delay of the communication between the concentrator and the optical fiber meter is the response delay of the optical fiber meter and the network delay, and the concentrator can simultaneously send a predetermined number of the optical fiber meters every preset time period. Send met...

Embodiment 3

[0045] See again Figure 5 with Image 6 Shown.

[0046] The present invention provides a method for high-speed meter reading based on an optical fiber network. The method includes:

[0047] The concentrator communicates with the optical fiber electric meter through the communication channel. The concentrator collects or configures the IP address and port of the optical fiber meter. The concentrator uses a data collection algorithm to start a single thread. In the thread, a predetermined number of intelligent The electric meter sends a meter reading frame and receives the response data frame of the optical fiber electric meter, so as to realize high-speed reading of all the optical fiber electric meters.

[0048] It is understandable that to achieve complete point-to-point communication, as many threads as the number of optical fiber meters need to be opened, and the concentrator is limited by operating speed and terminal resources. For example, the operating speed of the concentrat...

Abstract

The invention relates to an optical fiber network based high speed meter reading system, which comprises a concentrator, an Ethernet passive optical network and an optical fiber ammeter. A communication channel is established between the concentrator and the optical fiber ammeter through the Ethernet passive optical network. The optical fiber ammeter includes an optical network unit, a microcontroller and a monitoring unit. The optical network unit and the monitoring unit are both connected to the microcontroller. The monitoring unit transmits optical fiber ammeter data to a microprocessor, and the microprocessor transmits the optical fiber ammeter data to the concentrator so as to reach the beneficial effect of greatly improving the meter reading efficiency.

Description

Technical field [0001] The invention relates to a meter reading system of a power system, in particular to a high-speed meter reading system based on an optical fiber network. Background technique [0002] In the field of smart electricity consumption, the current meter reading method used is mainly to apply a concentrator to read the electricity consumption data of residents, and upload the electricity consumption data to the main station, and connect to the marketing system for electricity bill settlement and other tasks. Existing concentrators collect electricity consumption data of residential users, mainly using low-voltage narrow-band power carrier meter reading (PLC) and some wireless meter reading (470M micropower wireless). Due to the complex power equipment of low-voltage lines, there are many harmonics, and the lines run Lines and other problems are affected, line interference is large, and there are many sudden interferences, the success rate of data communication is ...
