Multi-protocol data acquisition gateway for intelligent building and data acquisition method thereof

Abstract

The invention relates to a multi-protocol data acquisition gateway for an intelligent building and a data acquisition method thereof, and relates to the technical field of networks. The multi-protocol data acquisition gateway solves the technical problems of complex structure, simple function, low reliability and few compatible meters in a data acquisition unit system. The gateway comprises a CPU module and a network communication module, wherein the network communication module is connected with the CPU module through a bus and provides a network interface. The gateway also comprises different types of data acquisition modules and a plurality of data service modules, wherein each data acquisition module is connected with the CPU module through a bus, and the different types of data acquisition modules provide different field device interfaces; the plurality of data service modules provide custom data for users through a network communication interface; and the data acquisition modules and the data service modules are respectively connected with an embedded database, and access data through the embedded database. The multi-protocol data acquisition gateway and the data acquisition method have the characteristics of capacity of acquiring different types of data, realization of real-time data processing simultaneously, and convenient on-site supervision and analysis.

Description

technical field [0001] The invention relates to a gateway and a data collection method thereof, in particular to a multi-protocol data collection gateway for building intelligence and a data collection method thereof. Background technique [0002] With the rapid development of China's economic construction, the issue of energy conservation and environmental protection has become a key issue that must be considered while developing my country's economy. At present, the energy consumption of buildings in my country accounts for more than 27% of the energy consumption of the whole society, and the energy consumption per unit building area is far higher than that of developed countries. Energy metering is the premise of building energy saving, and accurate metering equipment is the basis for energy metering. The formulation of building energy consumption standards, energy consumption evaluation, energy-saving operation management and energy-saving effect evaluation are all insep...

Problems solved by technology

However, because the GSM network signal is greatly affected by the strength of the terminal signal and the location of the equipment, the problems of information transmission delay and packet loss reduce the reliability and real-time performance of the system, and cannot ensure the safe operation of the field equipment. Therefore, the field acquisition device In addition to data collection, real-time monitoring capabilities are also required
