Data acquisition device for large-scale public construction energy consumption monitoring system

Abstract

The invention provides a data acquisition device for a large-scale public construction energy consumption monitoring system. A plurality of monitoring subnets are distributed in the whole monitoring building. Each monitoring subnet contains a data acquisition device, a remote transmission metering basal meter which is connected with the data acquisition device through an RS 485 bus, a remote transmission metering basal meter which is connected with the data acquisition device through an M-Bus bus and a remote transmission metering basal meter which is connected with the data acquisition device via a ZigBee wireless network. The data acquisition device realizes communication with different energy consumption individual metering basic meters by means of a bus or wireless; data can be transmitted to a monitoring centre through the network by a GPRS (General Packet Radio Service) module of the data acquisition device after being analyzed and processed. The energy consumption data are received and stored by the monitoring center and displayed to a user after being analyzed and processed; and a data management function is provided to the user to enquiry the historic energy consumption data. The data acquisition device has high data communication capacity and data processing capacity and high environmental adaptability of equipment.

Description

Technical field [0001] The invention belongs to the technical fields of wireless sensor networks, field buses, and embedded systems, and specifically relates to a data collector used in a large-scale public building energy consumption monitoring system. Background technique [0002] Building energy consumption, industrial energy consumption, and transportation energy consumption have been called the three "big energy consumers", and the energy efficiency of large public buildings in building energy consumption is particularly low. my country is in energy shortage, and it is of great practical significance to carry out energy consumption monitoring to obtain building energy consumption data in time to improve energy utilization. [0003] To carry out building energy conservation, the key to formulating energy-saving countermeasures is to obtain building energy consumption data in time, which can be obtained by constructing an energy consumption monitoring system. Large-scale public...

Problems solved by technology

However, these data collectors still have the following problems: 1) Sub-item measurement is generally not realized, and only energy consumption data such as electricity consumption or water consumption of a single item can be measured, which is not conducive to formulating more specific energy-saving measures

2) The communication between the data collector and the energy consumption base meter generally adopts the bus mode, and only one of RS485 or M-Bus is used, which makes the user have limitations in the selection and replacement of the base meter

[0005] With the development of embedded and wireless communication technologies, it is possible to improve the existing energy consumption monitoring system and solve the problem of single communication interface of energy consumption monitoring equipment.
