Unmanned ship ship-mounted intelligent terminal and control platform system adopting multi-protocol conversion

Abstract

The invention discloses an unmanned ship ship-mounted intelligent terminal and a control platform system adopting multi-protocol conversion. The intelligent terminal comprises a data protocol port module, a master control module and a control end module. The data protocol port module is used for providing an interface circuit enabling the master control module to be connected with a bus and ship-mounted equipment. The master control module is used for collecting data of sensor equipment, packaging the data and transferring the data to a CAN or an Ethernet bus. The control end module is used for receiving user commands and carrying out on-off operation on peripheral equipment. The data protocol port module comprises a CAN interface circuit, an RS 232 drive circuit, an overvoltage and overcurrent protection circuit, an Ethernet controller, an isolation transformer circuit, an RS 485 drive circuit and an optocoupler isolation circuit. The master control module is connected with the CAN bus through the CAN interface circuit and is connected with the sensor equipment through the RS 232 drive circuit and the overvoltage and overcurrent protection circuit or through the RS 485 drive circuit and the optocoupler isolation circuit. The intelligent terminal greatly reduces the number of wires used when the equipment is connected into the bus, reduces complexity of overall arrangement of the equipment and improves system stability.

Description

technical field [0001] The invention relates to the technical field of ship-borne equipment, in particular to an unmanned ship-borne intelligent terminal and platform system for multi-protocol conversion. Background technique [0002] In recent years, due to the strong competition for marine resources and the frequent occurrence of maritime accidents around the world, the development of unmanned ships that can undertake the functions of intelligence collection, anti-submarine, precision strikes, maritime search and rescue, and hydrographic surveys has become a research hotspot in this field. In addition to conventional navigation equipment such as GPS and gyrocompass, unmanned ships also need to carry various types of sensor equipment according to different tasks. The data that needs to be processed at the same time also coexists with various types, and the processing capacity is also huge. Most of the existing system schemes adopt centralized design schemes, connecting ...

Problems solved by technology

This method has the following disadvantages: 1) The processing speed of the controller is high, which will inevitably lead to an increase in cost; 2) The controller processing program needs to have data interfaces of different protocols at the same time, which increases the difficulty and cycle of program development; 3) Access The number of wires to the controller is large and the wiring is complicated; 4) Troubleshooting is difficult. When a certain device fails, the entire system needs to be checked, which increases the difficulty; 5) It is not easy to expand. If you want to add other devices later, you need to Redesign and modify the entire system
