Research On Communication Network And Acquisition Mode Of Electric Information Collection System

Electricity is national grid company to build strong information acquisition system an important component of the smart grid. Before the establishment of the system, due to production needs in the power industry, has established a collection of large variable power load management system of information, collect public information public distribution transformers for electricity distribution transformer collection systems, capture people meter system of resident consumers information, and so on. Construction of information collecting system for electricity, is to integrate these systems, large changes in the regional power supply company, small and medium sized three-phase transformers, low-voltage, low voltage single phase, residents, public distribution transformers and other six categories of users of electricity, power quality data acquisition in the distance. After the system is set up, the State grid Corporation of "full coverage"," full collection","full control" goal could be achieved.Electric construction of information collecting system on the one hand you want to have a large number of new terminals, along with a variety of systems have some older terminals. Regardless of the terminal capacity from the system, or a terminal type,; to complete the electricity information collection, can’t simply combine existing acquisition system simple. But you want to research a means of communication and gathering of information collection system for electricity solutions, as well as solve the problem of mass-transfer and storage of mass data acquisition brings and compatible terminal equipment under the existing acquisition system.1. In response to the current limitations of the230M wireless communications network, proposed a solutionforming a230M wireless network with high-speed networking.2. Inresponse to the current limitations of the GPRS/CDMA wireless public communications network, proposed a solutionusing flow monitoring and long message framing. 3. In order to solve themultiple communication protocolscollection, use the function mapping method of electricity information collection system.4. Through the use of data acquisition marks, message analysis plug-in, multi-modecollections according to way of channel characteristics, bulk storage technology, solve the multiple electric types user collection.
