Study on building electricity consumption data collection methods

Abstract

The stability of high energy consumption data acquisition system in addition to the traditional energy consumption data acquisition, processing and upload function, but also on the acquisition of communication protocol is analyzed and improved, to improve the accuracy of the data. Design breakpoint transmition to ensure data continuity, through the MD5 checksum AES encryption application design and enhance the security of data upload, provide accurate data services for the public building energy-saving emission reduction. 1. Introdution Large public buildings energy waste is very serious, there is a huge saving space. Traditional bulky data acquisition systems, real-time poor, severe signal attenuation, a limited number of plug-in devices. With the improvement of building energy consumption monitoring system for building energy consumption data acquisition requirements are also getting higher and higher. So this paper embedded development technology, C # programming language and VS2008 realized energy collector software features. Focus on energy consumption data collection protocol, energy security data processing method and data upload to do a more detailed study. 2. Research on energy consumption data acquisition and improvement of communication protocols Electricity meters comply with industry standard DL / T 645-1997 "multi-function meter communication protocol", it found that many traditional acquisition system resolution protocol is incorrect. Traditional data collection often lost count, the number of error affect the reliability of the measurement results, the measurement may lead to serious results completely unavailable.
