Research of the electrical energy measurement data acquisition engineering based on SCDMA

Abstract

The electrical energy measurement data is the basis of estimating electrical energy supply and sales related cost; also it is important information which analyzes the loss of electrical energy transmission and the efficiency of electrical energy consumption. The electrical energy measurement stations are not only distributed among buildings and the streets in the urban areas, but also have been disperses extensively in rural regions such as in the fields and along mountainous areas. Due to the features of dispersed measurement stations, it needs an efficient data-collecting network, which is with large capacity and coverage, to achieve the automatic collection of long-distance measurement data. SCDMA is a kind of wireless communication technique, where SCDMA stands for Synchronized Code Division Multiple Access. To construct specific data-collecting network for electrical energy measurement data by using SCDMA wireless communication technique, the problems associated with the establishment of wireless network should be solved; at the same time, the connection problem of SCDMA network bearing electrical energy measurement data collection service should be settled. This article, which is based on the view of engineering construction, utilizes the features of SCDMA's cellular network establishment technology and smart antenna technology to analyze and suggest the most appropriate electric wave transmission model for urban and rural areas respectively. It also mentions the accession and connection method to serve electrical energy measurement data collection and management, as well as facing-the-object data collecting pattern and device management model. These are applied in the engineering construction and have remarkably solved the base station selecting and signal coverage designs that are associated with SCDMA wireless network establishment, and they help to cope with the connection problems of electrical energy measurement data collection center, enhancing the real-time of electrical energy measurement data collection and building up excellent foundation for analyzing the loss of electrical energy transmission and the efficiency of electrical energy consumption.
