Two laser sensors that locate in the front of the system are installed on the jetty to detective the distance from the two points of the ship. The system can calculate the speed of ship based on the different distance in the fixed time. It also can calculate the angle between the ship and jetty according to the distance of the two points. The system adopts computer technology to detective the speed of the ships, record the docking process of ships and transfer the datasheets to the large display mounted on the jetty. Then, it can used to guide the docking and to prevent damaging the equipment of the jetty and ship because of the fast speed or larger angle during docking.

The industrial computer and PAC controller can be used in the severe environment. They are used for automatically search, catch, identify, follow-up the docking ships, control and show the detective process and deal with and record the datasheet of the docking ship. When the industrial computer gets any error, the main control PAC controller still can work and record **0 datasheets of ships. After the industrial computer repaired, the docking datasheets will be uploaded automatically to keep the entire system safety. It can replay and print the docking process according to the requirement. 

The key technology of the system is to develop the functional laser sensors with computer output interface (The IP of the laser sensor is Grade 2, no harm to peoples eyes), the detective range of the laser sensor is over **0m under no reflector condition. The precision is 0.*5m. Furthermore, developing friendly computer detective system, software interface and better PLC control system are also key tasks. 

Configuration of master control is desktop. It is composed by the following items: standard control box, industrial computer, programmable automation PLC controller，display, keyboard, printer and computer software.
