Construction management system of smart meter

Abstract

The invention relates to a construction management system of a smart meter. The construction management system comprises a master control device, a bridging electric meter and an auxiliary electric meter. The master control device is connected with the auxiliary electric meter and the bridging electric meter through wireless communication. When the master control device determines incapability of realizing wireless communication with at least one in the auxiliary electric meter and the bridging electric meter, the bridging electric meter is connected with the master control device through wired communication. The bridging electric meter is connected with the auxiliary electric meter through wireless communication so that the master control device is connected with the auxiliary electric meter through the bridging electric meter.

Description

technical field [0001] The present invention relates to a management system of a smart meter, in particular to a deployment management system of a smart meter which manages the deployment situation of the smart meter and maintains communication. Background technique [0002] Advanced Metering Infrastructure (AMI; also known as smart meter system) is basically composed of smart meters, communication systems, and meter data management systems. The main structures include the following: [0003] (1) The master-slave architecture (Server-Master-Slave) of "backend server-concentrator-smart meter". Among them, the connection between the back-end server (Server) and the concentrator (Concentrator) is through a wide area network (Wide area network, WAN), and the connection method includes mobile communication technology (3G, 3.5G, 4G); physical network line connection ( Such as optical fiber communication); or heterogeneous communication connection technology, for example, the bac...

[0006] However, regardless of the (1) or (2) architecture, the staff must have site survey capabilities or survey tools corresponding to the environment, otherwise it is difficult for the staff to find out the communication quality influencing factors of the deployment environment , if the installation is mandatory, it will avoid multiple communication breakpoints, resulting in a significant drop in overall communication efficiency

Moreover, if the survey tool is not a survey tool dedicated to the survey and deployment environment, the reference of the test results is relatively low, and there will be a considerable difference between the final on-site deployment effect and the expected effect of the on-site survey and its predetermined strategy. drop

[0007] Secondly, the (1) architecture cannot be applied to a more complex deployment environment

When the concentrator and the smart meter are connected by wireless communication, if there is an obstacle between the two, or the location of the concentrator and the smart meter is not good, such as the smart meter is configured in the iron meter box, the smart meter If it is installed deep in the house, the location of the smart meter is too high, or it is blocked by walls, signboards, or other obstacles, it will affect the communication quality between the concentrator and the smart meter, and even cause communication interruption.

In addition, in some countries' systems, it is forbidden to modify the meter, so users or staff cannot set the external interface of the meter antenna to allow barrier-free communication between the smart meter and the concentrator, and the function of wireless communication is equivalent to useless

[0008] In addition, when the concentrator and the smart meter are connected by wired communication (commonly narrow-band power line communication), the slave meter may be centrally installed in the power circuit of the master con
