Power concentrated-reading cluster system and method

Abstract

The invention provides a power concentrated-reading cluster system and method. The power concentrated-reading cluster system is a high-extension concentrated-reading cluster system. A power concentrated-reading cluster scheme of a cloud server is used; therefore, the traditional physical concentrator hardware equipment is removed; electricity meter data acquired from an electricity meter at a device side is directly uploaded to a network through an IOT transmission module; the physical concentrator in the traditional scheme is removed; all software functions in the physical concentrator run inthe power concentrated-reading cluster system of the cloud server; the condition that a lot of physical concentrators are installed in power distribution rooms of residents and factories can be avoided; unified deployment in a master station monitoring centre of a power grid is realized; all power grid data of intelligent electricity meters of power grid users is acquired and stored; the power concentrated-reading efficiency is greatly increased; the concentrated-reading human cost is effectively reduced; a cluster and other servers of a master station system of the power grid are maintainedand upgraded in a unified manner; and a professional engineer does not need to be additionally configured.

Description

technical field [0001] The invention relates to the field of electric meter reading, in particular to an electric power centralized reading cluster system and method. Background technique [0002] In the traditional power meter reading industry, there are a large number of physical meter concentrators; these physical concentrators are mainly installed in the power distribution room in the power consumption link, and are responsible for the collection, storage, and return of meter data. [0003] Such as figure 1 As shown in FIG. 1 , it is a structure diagram of a traditional power grid centralized copying system in the prior art. Generally, the existing technical solutions mainly include the following two types: [0004] 1. The existing power grid physical concentrator is mainly composed of an industrial bus (485 serial port, power carrier line, etc.) for collecting electric meter data, a single-chip microcomputer, and a mobile communication module (LTE 4G module) that comm...

AI Technical Summary

Problems solved by technology

[0007] 1. High cost of installation and commissioning: because the physical concentrator is installed in the power distribution room and scattered in the city's power grid exclusive equipment, there are a lot of installation, commissioning and maintenance costs

[0008] 2. Long maintenance cycle, slow troubleshooting, and high cost: The specifications and standards of physical concentrators were formulated more than 10 years ago, so this type of product also has a history of more than 10 years. Most of the CPUs of physical concentrators are designed with single-chip microcomputers. It can manage the data of 150 electric meters, the computing power is very limited, the cost of upgrading and expansion is very expensive, and professional electric qualification personnel are required for construction

Most of the physical concentrators are installed in the power distribution rooms of residents and factories. After a fault occurs, there is no special person on duty and cannot be dealt with in time.

The maintenance and warranty process is very complicated, resulting in the failure to guarantee the success rate of the power collection indicators

[0009] 3. Impossible to quickly expand and upgrade: The upgrade and expansion of the physical concentrator is limited by the processing capacity of the hardware. It can only be planned in advance in the power consumption planning in the early stage. If the deployment is added in the power distribution room later, it will be limited by many Due to constraints, high-quality services cannot be guaranteed, such as the size of the site, the wiring construction connected to the meter, the compatibility of meters of various standards, and the construction quality of the project, etc.
