Method and system for wireless concentrated collection and management of energy measurement data

Abstract

The invention discloses a method and a system for wireless concentrated collection and management of energy measurement data. The system comprises wireless measurement instruments, collectors, a concentrator, wireless GPRS communication modules, and a system management center. The system is characterized in that: the system adopts a quantification method, a timing method, a multi-channel redundancy communication technology, and a high efficiency forward error correction channel coding technology, such that power consumption is reduced, and reliability and collection success rate are ensured; different wireless interfaces and different communication protocols are adopted in the communication between each subsystems of the wireless concentrated collection and management system, different wireless transmission frequencies are adopted in different wireless interfaces, and a transparent data transmission method is adopted, such that wireless data communication reliability, system compatibility, system flexibility and system applicability are ensured. With the system and the method provided by the present invention, data information which is real-time, real and reliable is provided for management departments, and real-time monitoring, statistics gathering, and analyzing of measurement instrument operation status are realized, such that managing and administrating capacities of management departments are improved.

Description

technical field [0001] The invention relates to a method and system for wireless centralized copying management, in particular to a method and system for wireless centralized copying management of utility energy metering data. Background technique [0002] With the improvement of people's living standards, the expansion of buildings and the popularization of computer technology, the accuracy and timeliness of the traditional manual meter reading method cannot be guaranteed, and it can no longer meet the needs of social development. The user information of the IC card meter is stored on the IC card, which solves the current problems of difficult meter reading and charging, and plays a positive role in saving, but it cannot provide timely user usage information for real-time monitoring, which is not convenient for the management department. Data analysis management. Traditional wired centralized meter reading system, due to the difficulty of wiring construction, heavy install...

Problems solved by technology

However, the existing wireless meter reading system usually uses the concentrator to poll the wireless meter for data transmission, so that the wireless meter is always in the receiving state, because the wireless communication module consumes a large working current when working, making the wireless meter The watch consumes most of the energy needlessly, which greatly shortens the service life of the battery and limits the popularization and application of the wireless watch.

The polling communication mode requires the wireless meter to always receive the wireless signal in the air and process the response. Because the wireless signal in the air is complex and susceptible to interference, the communication reliability is greatly reduced, and the wireless communication channel is often in a busy state, causing the wireless communication system to fail to work normally. , the wireless system cannot collect the information in the meter in real time and reliably, and the data copying rate cannot be guaranteed, so it cannot realize real-time monitoring of user information and the working status of the wireless meter, and cannot provide real and reliable data management information for the management department
