Design And Implement Of Network Protocol For Electric Power Control System Wireless Private Network

With the rapid development of society, the power demand, which occupied an important and significant position in the energy structure, has been amplified, and brings great challenges to the power control system. The number of remote load control terminal continues to increase, data volume increases, the power control wireless network has been difficult to meet the application requirements. Based on the power control wireless network architecture research, combined with wireless communication affected by topography, the same frequency interference, limited frequency point, equipment maintenance is difficult, the business does not support active reporting and other practical problems, designed a new type of electric power control system wireless network protocol and implement it. The completed work as followed:(1) Do the entirely design of power control system wireless private network. Firstly, analysis the power load control of wireless network, study its running scene. Then put forward the power control system wireless private network functional requirements and performance indicators. Then, done the power control system wireless private network of the overall design, respectively, from the overall framework, network topology, interface design, frequency allocation, protocol design, including protocol design is the key, in the third chapter discussed separately.(2) Do the design of power control system wireless network protocol. Firstly, the network protocol is analyzed, and then the data link layer network is designed, which is divided into three parts, including frame format design, network message type design and network process design. Networking process design and design two kinds of situations for direct networking process design and relay networking process, each kind of network flow design is subdivided into net, in the net, off net three steps. In addition, there are the key technologies involved in the network process load balancing, CSMA/CA and retransmission mechanism to do the implementation process design.(3) Do the power control system network of private network protocol software implementation. First design the overall software architecture, followed by the construction of the operating system and the TCP / IP protocol implementation, then do the network protocol for software level of task partitioning and implementation process design, eventually completed the software implementation.(4) Do the base station and terminal test,which installed designed network protocol. Respectively in the laboratory and actual test, analyzes and discusses the experiment and actual environment test results. Test results show that the electric power control system wireless private network design scheme is practical and feasible, has practical value and practical significance.
