Embodiment approach

[0027] Such as figure 2 As shown, in the prior art, the power load control terminal of the low-voltage user electricity information collection system is generally composed of an electric energy meter, a collector and a concentrator, wherein the electric energy meter is connected to the user (not shown in the figure) and is used to record the user The electricity consumption information includes the user's identification, electricity consumption, etc. The collector is used to collect the electricity consumption information of the electric energy meter, and the concentrator is used to collect the electricity consumption information collected by the collector. The collector is set at Between the energy meter and the concentrator, the collector and the energy meter are connected through a narrowband power line, and the collector and the concentrator are connected through a broadband power line. When collecting user electricity consumption information, it is necessary to first coll...

Abstract

The invention discloses a low-voltage user electricity utilization information acquisition system and method. The method specifically comprises the steps that an electric energy meter records electricity utilization information of a low-voltage user; a 485 communication port of a concentrator and a 485 communication port of the electric energy meter are connected in series through an R-485 data transmission line so as to carry out data transmission, and the recorded electricity utilization information of the low-voltage user is transmitted to the concentrator; and the concentrator receives and stores the low-voltage user electricity consumption information recorded by the electric energy meter. The collection function of a collector is omitted, and the technical requirement that two sets of terminal collection devices and two information channels can be completed originally is met, and only one set of low-voltage concentrator collection device is used for achieving all collection of electricity utilization information of the low-voltage users in the public transformer district. The maximization of economic value is achieved, a large amount of investment of manpower and material resources is reduced, the utilization rate of equipment functions is improved to the maximum extent, and the system and the method are simple in design, low in application cost, easy to operate, flexible, convenient to carry and high in applicability.

Description

technical field [0001] The invention relates to a system and method for collecting electricity consumption information of low-voltage users. Background technique [0002] The functional limitations of the low-voltage user electricity information collection system in the public substation area that has been put into use at present, the installation and operation mode can only be: public substation power information collection terminal + low-voltage customer concentrator installation and operation mode, which is equivalent to a public substation must Installation and operation of two sets of terminal collection equipment can realize the collection of low-voltage user electricity consumption information. Not only is the installation process extremely irregular, but it also increases a large amount of investment in manpower and material resources, increases the cost of equipment operation and maintenance, and increases the safety risk in the process of on-site operation and main...
