Embodiment 1

[0030] figure 1 It is a schematic structural diagram of a power consumption information collection substation provided in Embodiment 1 of the present application.

[0031] The substation adopts OLT (Optical Line Terminal, optical cable terminal equipment) 11 as a platform for gathering power consumption information, and provides functions of network concentration and access.

[0032] The optical cable terminal equipment OLT11 is used to receive the control command issued from the network side, analyze the control command, obtain the target electric energy meter identification and control information, and send the target electric energy meter identification and control information to the user side through the optical fiber; simultaneously receive The user side returns the power consumption information, and uploads the power consumption information to the network side.

[0033] After receiving the control command, the OLT11 analyzes the issued control command according to the p...

Embodiment 2

[0037] figure 2 It is a schematic structural diagram of a power consumption information collection substation provided in Embodiment 2 of the present application.

[0038] The substation may also include a POS (Passive Optical Splitter, passive optical splitter) 12, which is used to divide the optical fiber connected to the OLT 11 into multiple branches for connection to the user side.

[0039] POS12 is a passive device, which divides an optical fiber connected to OLT11 into multiple branches, so that one OLT11 can serve multiple users. Its splitting ratio can be 5:95, 50:50, 25:75, etc. The splitting ratio needs to be calculated according to the actual conditions such as the distance from the user side to the OLT11, insertion loss, etc., and the maximum distance between the user side and the OLT11 is 20km , which is also the maximum transmission distance of optical fiber, which can meet the electricity consumption information collection requirements of general urban or urba...

Embodiment 3

[0041] image 3 It is a schematic structural diagram of a power consumption information collection terminal provided in Embodiment 3 of the present application.

[0042]The terminal includes: ONU (Optical Network Unit, optical network node) 31 and a power meter 32;

[0043] ONU31 is used to receive the target electric energy meter identification and control information sent by the electrical information collection substation (not shown in the figure), find the corresponding electric energy meter 32 according to the target electric energy meter identification and control information, and perform data interaction with the electric energy meter 32, Obtain electricity consumption information; send the acquired electricity consumption information to the electricity consumption information collection sub-station through optical fiber.

[0044] The electric energy meter 32 is a general digital electric energy meter for providing electricity consumption information.

Abstract

The invention discloses a substation, a terminal and a system for collecting the information of electricity consumption. The system comprises a master station, a substation and a terminal, wherein the substation consists of an OLT (optical line terminal) as network equipment and a POS (passive optical splitter); and the terminal consists of an ONU (optical network unit) and an electric energy meter. The OLT receives and resolves a command issued by the master station, and sends the resolved identifier of a target electric energy meter and the control information to the ONU through the POS on optical fiber; the ONU collects the information of electricity consumption from the electric energy meter corresponding to the identifier of the target electric energy meter according to the received control information; and the ONU sends the information of electricity consumption to the OLT through the POS on the optical fiber after the information collection, and the OLT further uploads the information of electricity consumption to the master station, so as to complete the entire process of information collection. By applying the technical scheme, the invention substitutes the optical network for the complex original local network, thus optimizing the network structure and further reducing the complexity of the system for collecting the information of electricity consumption.

Description

technical field [0001] This application relates to the field of electric power, in particular to a substation, terminal and system for collecting electricity information. Background technique [0002] With the continuous improvement of power consumption management level, manual meter reading can no longer meet people's needs. Remote meter reading gradually replaces manual meter reading, which solves the problems of large error and heavy workload of manual meter reading. [0003] The existing electricity consumption information collection system for remote meter reading includes master station, substation, electric energy meter and communication network among them. The master station performs data interaction with the sub-station through the wired network; the sub-station and the electric energy meter exchange data through the local network to obtain relevant data of the electric energy meter. In this way, the master station can obtain the data of the electric energy meter a...
