Result background:

In recent years, the research and development of surface oil spill monitoring and recovery systems for unmanned boats has achieved the task of unmanned autonomous monitoring and recovery of surface oil spills in dangerous environments, solving the problem of unsafe manual operations.

Introduction to the results:

The unmanned water surface oil spill monitoring and recovery system consists of subsystems such as all-round video monitoring, oil film area measurement, oil spill sampling and collection device, mounting platform, and unmanned boat path planning and tracking. The system is carried by the "Haiteng 01" unmanned boat and can rush to the scene of the incident at a high speed of 40 knots; a 360-degree video monitoring subsystem composed of 6 wide-angle cameras sends the video back to the monitoring center of the shore-based or mother ship in real time; When oil spill pollution is discovered, the area of the oil spill pollution is measured through the stereo vision system, and the oil spill sampling and collection device is applied to the oil film area through remote control instructions; According to the oil film area measured by binocular stereo vision and the distribution of underwater obstacles measured by sonar, the path for oil spill collection is planned, and the collection of oil spill on the water surface is completed along the planned path. After completing the task, the oil spill collection device will be automatically recovered to the bow deck and returned home with the collected oil spill. The entire process of transportation, release, operation and recovery of the oil spill sampling and collection device is monitored remotely in real time through two cameras located at the bow of the boat.

Technical advantages:

The system has the characteristics of high-speed transportation, remote control, and real-time video transmission, and can be further developed for unmanned operations for tasks such as monitoring of other water pollution and emergency search and rescue.

1. There are three working modes: in open waters, the fully self-propelled mode can autonomously track paths and avoid obstacles; in relatively complex waters, the semi-autonomous mode can autonomously track paths and avoid obstacles through remote video remote control; in complex waters, the fully remote control mode has obstacle alarm function to ensure safety.

2. The control system has an open interface and can be connected to various communication navigation equipment and task equipment through RS-232, RS-485, USB, CAN bus and Ethernet to facilitate further application development.

3. It can be based on three types of hardware platforms: PLC, embedded system and industrial computer, and can meet different needs in terms of size, power consumption and reliability.  This system has realized unmanned operations for monitoring and recovering oil spills on the surface. The "Haiteng 01" has a carrying capacity of 2 tons and sufficient deck area. It can be replaced with different carrying equipment and further developed for hazardous operations in other fields.
