Building energy-saving monitoring data acquisition device

Abstract

The invention discloses a building energy-saving monitoring data acquisition device. The structure of the data acquisition device consists of a low power consumption transceiver A, a clock circuit B, a central processing unit C, a network interface circuit D, a storage circuit E, a relay circuit F, a buzzer circuit G, a reset circuit and a crystal oscillator circuit H, wherein the low power consumption transceiver A, the central processing unit C, the network interface circuit D and the storage circuit E form a main circuit; the relay circuit F and the buzzer circuit G provide an alarm function for the data acquisition device; and the reset circuit and the crystal oscillator circuit H provide a necessary support for a singlechip processing unit. The arithmetic unit consisting of the conventional analog circuit is substituted by adopting the central processing unit, so that validity check and multiple automatic compensating functions of data are realized, high-precision monitoring of the data is realized, the problems of the conventional data acquisition device on the aspects of stability, reliability, measurement precision and the like are solved, and the protective capacity of the data acquisition device under over-current and over-voltage conditions is perfected.

Description

Technical field: [0001] The invention is a special device for building energy-saving data collection using an embedded microcomputer system, which has the functions of data collection, data processing, data storage, data transmission, field equipment operation status monitoring, and fault diagnosis. Background technique: [0002] Energy conservation is one of the important development goals of many industries, especially in public buildings. Although there are many types of data collectors in the prior art, they rarely have the function of energy-saving monitoring, and cannot realize the integration of functions such as data collection, data storage, data processing and analysis, system management, system operation status monitoring and fault diagnosis, and are difficult to complete. The task of automatically transmitting various energy consumption data and information to the upper-level data center greatly increases the difficulty of energy-saving monitoring. Invention co...
