A Data Acquisition Method Based on Energy Audit

Abstract

The invention relates to a data collection method based on an energy audit. The data collection method comprises the steps as follows: establishing connections, namely establishing connections of collectors and data centers for informing energy management systems of numbers of the collectors, and the numbers of targets collected by the collectors; inquiring and sending data which are not sent; regularly sending the data; maintaining the connections. The data collection method based on the energy audit disclosed by the invention has the innovation points that the collectors send data once, and then multiple energy management systems can receive required data simultaneously to greatly improve the transmission efficiency of the data; local temporary storage of the data is realized; continuous transmission of the data is intelligent and fast, and manual intervention is not required to prevent a loss of important data in exceptional cases.

Description

technical field [0001] The invention relates to a data collection method for energy collection equipment, and belongs to the technical field of industrial control data collection. Background technique [0002] In modern energy management systems, various metering data need to be collected. Since there are many meters in a system, the metering data is generally collected and packaged by several energy data collectors (hereinafter referred to as "collectors"), and then forwarded to the data center of the energy management system ( hereinafter referred to as the "Data Center"). [0003] In the previous system, the collector only needed to send data to one data center. Modern energy management systems have the concept of energy auditing, and the raw data of the collector needs to be uploaded to multiple different data centers to ensure the fairness of the data. This is a huge performance overhead for embedded devices such as collectors. [0004] The data center needs to be m...

Problems solved by technology

[0006] The collection method adopted by the existing energy management system cannot meet the needs of the collector for multiple data center transmission in terms of data upload; in terms of continuous transmission, some systems save the historical data locally in the collector, and then manually transfer the data to the collector. Export from the collector and then import to the data center. The disadvantage of this method is that manual intervention is required, and the degree of automation is insufficient; other systems use a simple TCP connection to continue uploading from breakpoints. This method requires multiple collectors to resume uploading at the same time , it will significantly reduce the performance of the data center and slow down the speed of resuming uploads

In this way, even if the network is restored, there will still be data gaps for a long time, making the energy management system unable to perform data analysis well
