Data acquisition method of electricity consumption information acquisition system

Abstract

The invention discloses a data acquisition method of an electricity consumption information acquisition system. The method is used for a power consumption information acquisition system local network.The local network comprises energy routers and an energy controller; the local network is a half-duplex communication network, and the data acquisition method specifically comprises the following steps: the energy controller customizes a data demand for each energy router, and each energy router actively reports data to the energy controller according to the data demand; the energy controller realizes automatic data collection based on a channel competition mechanism with carrier sensing and conflict avoidance, and the data collection method further comprises the step of uploading data by adopting a power utilization data uploading strategy based on a distributed structure. Compared with the prior art, the data acquisition method has the advantages of high stability, high response speed and high efficiency.

Description

technical field [0001] The invention relates to the field of electricity consumption information collection systems, in particular to a data collection method of the electricity consumption information collection system. Background technique [0002] The power consumption information collection system generally adopts a three-level structure of master station, collection terminal, and smart energy meter. The master station is responsible for the collection and processing of information on the entire network, the collection terminal is responsible for the collection and processing of information in the station area, and the smart energy meter generates various data waiting copying. The acquisition terminal and the smart energy meter construct the local communication network of the acquisition system. Its structure is generally bus or star, using half-duplex communication in the server / client mode. Traditional data acquisition is generally initiated by the acquisition terminal...

Problems solved by technology

This acquisition method has a high occupancy rate of the communication channel, especially when the smart energy meter has not yet generated the current reading data. Polling, resulting in a decline in the success rate of acquisition, a large number of invalid copying caused a great waste of channel resources

[0003] In order to support the ubiquitous power Internet of Things application on the customer side, the new generation of smart energy meters (energy routers) and the new generation of collection terminals (energy controllers) adopt a modular design concept to support more flexible data transmission and management methods, allowing more In the future, all professional monitoring and sensing devices may be connected to the system, which brings great trouble to equipment operation and management, and makes the communication performance of the ubiquitous power Internet of Things on the customer side The requirements have been significantly improved. The existing collection methods are difficult to meet the data quality requirements of full data collection. It is necessary for the local communication of the system to adopt a more efficient and real-time communication method to meet different information collection needs.
