Research And Implementation Of Multi Hop Transport Protocol For Power Monitoring Network In Complex Environment

In recent years,with the economic growth rate ranking highest in the world,China's economy has made remarkable achievements.Behind this great achievement,the stable supply of electric power has played a very important role.Nowadays,human society has entered the information age,however,electricity is still the important support for national economy,production and life.With the rapid development of the Internet and the Internet of things,the demand for power supply and transmission stability of the social economy has been increasing.During the "12th Five-Year" period,the State Grid Corporation of China also put forward the slogan of the construction of strong smart grid.The reliable supply and stable transmission of power system has become a hot research topic.To ensure the reliability and stability of power transmission,it is necessary to monitor and manage the power system.At present,most of the work is operated manually.The limitations of this operation mode highlights in some complex environments.The power monitoring system for electric power facilities arises at the historic moment.The power monitoring system can realize the function of data collection,remote monitoring and fault analysis.This thesis focuses on the research of electric power monitoring system under complex environment.Combined with the current communication technology and the power monitoring system network frame,this thesis puts forward the power monitoring system design in which wireless sensors network is responsible for data collection and microwave communication for data transmission.According to the scheme,this thesis introduces some important reliable transport protocol design technology such as acknowledgement feedback,selective retransmission and malfunction detection,and devises a new multi hop reliable transmission protocol applying to network model and transmission requirements of power monitoring system,which supports acknowledge feedback for receiving,selective retransmission for loss,timeout management for transmission,detection and location for malfunction etc..After that,protocol verification platform is built including hardware circuit,software platform and debugging platform design.Through the system data test by single source node and multi nodes,and connecting this system to the public network for remote data collection,the protocol presented in this thesis is verified to realize reliable transmission,selective retransmission and malfunction location.Also,it is verified that the new power monitoring system design is suitable for remote monitoring,node communication and fault analysis.The practical application ability and application value of this protocol design is reflected in an extended utilization.
