The Applied Research Of Building Energy Consumption Data Collector Based On Embedded Linux

With the continuous development of urbanization in China, the huge shortage of conventional energy consumption, and reduce the waste of energy consumption has become an urgent need for economic development and social civilization. Due to the rapid growth of China’s construction industry, building energy consumption accounts for the proportion of total energy consumption, there is a huge energy saving space in the control of building energy consumption. To achieve the first condition of building energy efficiency is to master the building energy consumption, the establishment of public building energy monitoring system is very necessary; it can promote us to make objective and accurate evaluation of building energy consumption and to develop appropriate standards for energy conservation. But the current energy consumption monitoring system has some problems, such as the basic energy consumption data collection is not accurate, the operation is not stable and so on, and in some ways, it hinders the application of energy saving technology. Aiming at the problem of inaccurate data acquisition, a building energy consumption data acquisition system based on embedded Linux operating system is designed in this paper.Firstly, this paper expounds the present situation research background and the domestic and international building energy consumption, are the main content of the research. Then according to the functional requirements of data acquisition for data acquisition for the overall program design, and on this basis, we introduced the embedded system.The building energy consumption data acquisition system is composed of two parts:hardware and software. The hardware design of main control module and peripheral circuit module two parts. Main control module selects the AT91SAM9260 as embedded processor, peripheral circuit module with power module circuit, reset circuit, communication interface circuit, TF card data storage circuit and network interface circuit based on the network interface chip dm9000. Design of the system hardware can not only satisfy the various features of the data collector, and ensure the stability and accuracy of the equipment. Secondly in the software aspect, to build the embedded Linux operating system as a platform, including building the cross compile environment, establishment of bootloader, Linux tailoring and transplantation of file system creation, the realization of the embedded Linux operating system for data acquisition hardware management. After application of the design, including the use of embedded server module configuration, Web-based way of network-related parameters, to achieve basic energy consumption data collected by the data acquisition module 485 interface for communication, with an embedded SQLite database for data centralization storage and processing based on TCP/IP protocol data upload module and data center energy consumption through the completion of the communication packets XML format so that the data collector to run properly.In this paper, the embedded building energy consumption data acquisition system uses an open interface, universal protocol and standard Linux operating system; so that the collector has a stable and good scalability.Building energy consumption data acquisition research study can give some reference value for other areas of data acquisition.
