Research On System Of Broadband Wireless Private Network In TD-LTE230 Power Marketing

As the main communication channel of information interaction for electric power marketing system and electricity information collection system,the coverage ability,system capacity,security and stability of wireless private network have laid a solid foundation for reliable power load control and accurate electricity information collection.At present,the 230 MHz wireless network that is widely used in the power system causes the scale of the system,the communication rate and the channel resources are close to full load.This situation has become a bottleneck,which restricts the further development of electric power marketing system.In order to make up the deficiency of the existing marketing network,this thesis proposes a new technology of constructing a mixed network by upgrading the existing 230 MHz wireless network based on the WSN technology.Firstly,this thesis analyses the current situation of the electric power communication network and chooses the WSN technology to construct the mixed network through the comparison of several kinds of communication technology.Then,puts forward the detailed network scheme and private network construction scheme on the basis of the retention of the existing 230 MHz network terminals.Finally,according to the network scheme and the application environment,this thesis designs a electric power marketing terminal system including the hardware design scheme and the implementation scheme of each module,analyses the software function architecture,and gives the design scheme of the main program and communication program.
