Public utility meter based data acquisition system and method

Abstract

The invention provides a public utility meter based data acquisition system and method. The data acquisition system includes a public utility meter, an intelligent electric energy meter, a concentrator and an acquisition master station. The public utility meter automatically wakes up according to a set cycle, and is in connection with the intelligent electric energy meter in a short distance wireless communication way. The intelligent electric energy meter and the concentrator, and the concentrator and the acquisition master station are both in bidirectional connection. Directed at the characteristics of the public utility meter data acquisition system communication link, short distance wireless communication and broadband carrier / micropower wireless communication technologies are adopted sectionally so as to avoid communication interference and communication barrier, and short distance transmission ensures the stability of a short distance wireless communication network. At the same time, the system and the method provided by the invention can fully meet the data copying and reading of a public utility meter, comprehensively consider the field installation environment of various meters, and have the characteristics of high data information transmission rate, short acquisition cycle, strong reliability, small engineering implementation difficulty, and good practicability.

Description

technical field [0001] The invention belongs to the technical field of electric power system data acquisition, and in particular relates to a data acquisition system and method based on utility meters. Background technique [0002] Public utility meter data acquisition is an important business in the future power system. It provides basic data for energy efficiency analysis of each meter data, rational use of resources, and comprehensive business development. At present, domestic utility meter information collection business technologies mainly include: power line communication technology and wireless public network (GPRS, CDMA, etc.) communication methods. [0003] Power line communication technology includes narrowband power line communication and broadband power line communication. Narrowband power line communication technology refers to low-voltage power line carrier communication technology with a carrier signal frequency range of ≤500kHz. It has the characteristics of...

Problems solved by technology

[0005] At present, all parts of the country are vigorously promoting household water, electricity, gas, and heat. However, since the management of each industry has its own system, each carries out work according to its own industry model. There are many similarities, but due to industry management reasons, resource sharing cannot be formed, and the development of smart metering in various industries is unbalanced. The smart metering and remote copying of the other three meters have not yet formed a system, which cannot meet the modern management requirements of enterprises. , and cannot provide better service to customers
