Design Optimization Of Telemetry And Remote Control Of Navigation Mark In Ningbo Aids To Navigation Department

Ningbo Zhoushan sea area is under the jurisdiction of Ningbo Aids to Navigation Department,Ningbo Zhoushan port is a world-wide port,with the continuous development of water transportation,the need for the usability,security and reliability of the operation of water transport industry is also increasing.As an important navigation aid for water transportation,the normal performance of navigation mark is directly related to the navigation safety and navigation mark of the ships on the water.For many years,the working state of the AIDS to navigation often requires the AIDS workers to collect the AIDS to navigation data in the sea area where the AIDS to navigation are located,but the navigation mark is often in places such as rapids,shoals and reefs,it is very difficult for the navigation mark workers to go to the field for inspection and maintenance.With the development of science and technology,electronic,wireless communication facilities and network measures are advancing rapidly,it provides scientific and technological support for the realization of navigation mark telemetry and remote control.Through the implementation of navigation mark telemetry and remote control function,it can greatly improve the management efficiency of AIDS to navigation,At the same time,Ningbo Aids to Navigation Department as the management department of navigation mark can work in a more timely and first-hand way.To carry out remote control and telemetry of navigation marks is to meet the needs of the current development and prosperity of the maritime industry.Based on the practical needs of the construction of navigation mark telemetry and remote control system,and based on the research and analysis of the current situation of the development of the telemetry and telecontrol technology of the existing AIDS by the maritime administration at home and abroad,combined with the actual situation of Ningbo Aids to Navigation Department,such as the large number,scattered distribution and changeable sea conditions of navigation marks,according to the needs of the existing navigation mark business system,the telemetry and remote control system of Ningbo Aids to Navigation Department is optimized.At last,all the documents of the remote control solution of Ningbo Aids to Navigation Department are sorted out,research is carried out from the aspects of overall scheme architecture,network system composition,database server and application software design,terminal RTU main circuit design,reliability and availability analysis etc.Using high performance 32-bit embedded ARM system + PIC single chip microcomputer + GPS + GPRS / GSM modem to develop telemetry and remote control terminal RTU.At the same time,according to the actual situation,the communication scheme with GPRS as the main mode and GSM SMS as the auxiliary mode is determined,considering not only the stability,maturity and full coverage of the network,but also the low communication cost and flexible selection,keep the initiative of choosing communication mode.A reliable and easy-to-use buoy telemetry and remote control system has been built.
