Remote Electricity Meter Reading System

According to automated meter reading in power systems technology, embedded control systems technology, data communication technologies such as the development trend of remote electricity meter reading system to become the power sector management, analysis, data processing power of an important choice measures.In this paper, as remote electricity meter reading system in a subset of the main data collection terminal on the part of the development of specific on the ongoing development of multi-functional meters, detailed description of electric energy measurement principle, hardware components and functional modules, and software development processes, and so on, to show a more complete acquisition of the electric energy consumption of electricity in the entire remote meter reading system in the role.In the hardware, the balance-meter site meter reading and remote meter reading needs, we can achieve wireless meter-reading scene, but also to achieve the centralized remote meter reading methods. Specific method is: use of a common power measurement on the basis of chips ADE7755, using SCM as a processor, infrared emission, receiving circuit, achieving the scene wireless meter reading functions with carrier printed circuit boards, completed the data collection Upload, achieving a long-distance data centralization and reproduced. Furthermore, in order to ensure that the whole system reliability and stability, and in meter design a separate hardware clock chip 8563, the meter provides a reliable benchmark clock in the collection of data storage, the use of non-volatile ferroelectric memory , the data provide a safe and secure storage of data retention, for the entire long-distance electricity meter reading system provides a reliable data base. In the connecting carrier boards treatment, the use of a three-way so that the meter can-do not change the overall structure of the hardware under the premise of the mere passage of the replacement carrier' s carrier boards different ways, corresponding to receive updates, send procedures, will be able to adapt to different remote data centralized, so that the meter can easily embark on the road of serialization.In the software, made full use of the characteristics and SCM meter transmit data collection features, the direct use of assembly language, in accordance with GB and Southern Power Grid agreements related programming. Fully taken into account the actual use of a variety of unusual approach, to ensure accurate and reliable meter run, improved Multi-meters information on the long-range response speed and accuracy.The multi-function meters, has completed initial development, the ongoing experiment related to the scene, through more than half a year since the installation of test operation, its running good, basic to the design requirements...
