Fuel distribution system and method for amphibious unmanned ship

Abstract

The invention relates to the technical field of unmanned ships, in particular to a fuel distribution system and method for an amphibious unmanned ship. The fuel distribution system comprises a main control system, two or more fuel tanks, a distribution system body and a monitoring system; the distribution system body is provided with a fuel filling pipe, a fuel outlet pipe and a distribution pumpwhich correspond to the fuel tanks respectively, and the fuel filling pipe and the fuel outlet pipe are communicated with the corresponding fuel tanks and are used for inputting and outputting fuel for the corresponding fuel tanks respectively; the monitoring system monitors the fuel quantity of each fuel tank and feeds back the oil quantity to the main control system, and the main control systemcontrols the distribution system to complete the fuel quantity distribution among all the fuel tanks. By means of the fuel distribution system and method for the amphibious unmanned ship, fuel quantity sharing between the navigation fuel tank and the land-machine fuel tank is achieved, and the fuel use efficiency and the endurance capacity are improved; the fuel quantity of the fuel tanks on the two sides of a ship body is evenly controlled, and the stability of the ship body during operation is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned ships, in particular to a fuel distribution system and method for amphibious unmanned ships. 【Background technique】 [0002] With the advancement of automation and computer technology, more and more machine products such as unmanned vehicles / unmanned ships are used in daily life, especially amphibious unmanned ships have both the functions of land vehicles and water ships, combining the dual functions of automobiles and ships. The advantage is that it can exert unique performance on land and water and in the junction area of ​​water and land. It can make up for the shortcomings that unmanned ships cannot go ashore by themselves and unmanned vehicles are difficult to navigate in water. It has a very broad application prospect. [0003] The space of existing amphibious unmanned ships is limited. In order to meet the needs of stealth, the height of the hull is reduced, and the control equipment an...

Problems solved by technology

The above multiple fuel tanks are all set independently. In the actual work of the amphibious unmanned ship, the following problems inevitably exist: when the amphibious unmanned ship has heavy land operations and the fuel in the land machine’s fuel tank is not enough, even if the navigation fuel tank Sufficient fuel will not play the role of fuel reserve, and it is still necessary to wait for the fuel tank of the land-based aircraft to be refueled before continuing land operations; Even if there is fuel, it cannot be used as reserve fuel to support the sailing engine; especially for the fuel tanks located on both sides of the hull, when the fuel consumption of the fuel tanks on both sides is unequal due to uneven efficiency of the engines on both sides, unequal output against wind and waves, or turning operations, etc., Uneven remaining oil may cause the center of gravity of the ship to shift, thereby affecting the balance and stability of the ship. It is necessary to control the ship's heel, trim, draft, stability or stress by increasing the ship's ballast water system, which greatly increases the amphibious safety. man ship workload
