Description

Building Energy Data Collector

technical field

The utility model relates to a building energy consumption data collector.

Background technique

Data collectors include batch data collectors and wireless data collectors. The data collector is an automatic device with on-site real-time data collection and processing functions. It has real-time collection, automatic storage, real-time display, real-time feedback, automatic processing, and automatic transmission functions. The existing data collectors collect and exchange data by wired communication, that is to say, the meter data is collected by wired, and the exchange of electricity consumption information between the metering device and the master station is also exchanged by wired communication. Its disadvantages: First, it uses wired communication to collect electric energy meter data, which not only requires wiring and large investment, but also high maintenance costs. If the line is slightly damaged, the signal cannot be exchanged; second, the scope of use is small, currently limited to Trials in the community cannot be widely promoted and applied in the entire urban area. At the same time, in the existing collectors, generally one data collector only supports one type of metering device, and the cost is relatively high. In order to scientifically and standardizedly build the energy consumption monitoring system for office buildings of state agencies and large public buildings, unify the classification, sub-item methods and coding rules of energy consumption data, and realize real-time collection, accurate transmission, scientific processing and effective utilization of sub-item energy consumption data. Storage, in order to provide data support for determining building energy consumption quotas and formulating a price increase system for building energy consumption exceeding the quota, it is necessary to design a collector specially used for collecting building energy consumption data.
