| From the beginning of 2009, State Grid of smart meters of large-scale centralized bidding and total electric information acquisition 3.16 million, to achieve the user information automatic collection total coverage of more than 80%, for the marketing of the State Grid, safety in production and management has played a positive role. With the continuous development of the technology of computer science and information technology, to China’s smart grid with a successful application case of electric information acquisition system, foreign power companies gradually by AMR (automatic meter reading) single time collect user information and through the network reached power company’s unidirectional information system into AMI (Advanced Metering Infrastructure) comprehensive two-way exchange of information system. It supports remote control, remote switch, power meter positioning and real-time information feedback, real-time pricing etc..According to domestic and foreign use of electric information acquisition system needs analysis, introduces the design principle of electric information acquisition system, key technology and data acquisition technology is used to realize the. Discussion with electric information acquisition system design, function and data collection implementation.DF6100 electric information acquisition system mainly consists of data acquisition subsystem, data application subsystem and peak load management subsystem, combined with the national grid electricity information acquisition system design standards, and taking into account the foreign design the concept, realize the full function module, data integration acquisition. DF6100 power information acquisition system to support real-time multi tasking operating system, has a rich communication protocol library, support DLMS/COSEM protocol, with good operability, security, stability. |
