[0001] The present invention relates to the technical field of the main propulsion auxiliary system of unmanned surface vessels, and in particular to a seawater cooling control system and a control method for unmanned surface vessels. Background Art

[0002] Unmanned surface vessels have shown extensive application potential in multiple fields such as marine environmental investigation, patrol and monitoring, and maritime search and rescue due to their ability to flexibly carry a variety of payloads. Many key devices of the propulsion system of unmanned surface vessels need to be equipped with efficient and reliable cooling mechanisms to maintain normal operation, such as diesel engines, gearboxes, thrust bearings, intermediate bearings, and shaft seal devices.

[0003] In the prior art, unmanned surface vessels usually are equipped with a set of seawater cooling systems, which are operated by a remote control station, so as to supply cooling seawater to the mechanical equipment that needs to be cooled through the seawater cooling system. However, since there is no crew on board the vessel, and the long-distance communication delay based on the remote control station results in poor control effects. Especially when the cooling water pump fails, from the alarm information being sent to the remote control station, and then after manual judgment and sending instructions to enable the standby water pump and switch relevant valves to the remote control station, the operation time and communication delay in this process may cause the mechanical equipment to lack sufficient cooling water in a short time, thus triggering a high-temperature alarm, and even causing damage to the propulsion equipment in severe cases. Summary of the Invention

[0004] The applicant of the present invention aims at the above-mentioned disadvantages in the existing production technology, and provides a seawater cooling control system and a control method for unmanned surface vessels, which can achieve precise control of the cooling pipeline system when the unmanned surface vessel is in semi-autonomous or fully autonomous navigation. The control method is simple and efficient, and can effectively avoid the adverse effects of communication delay on the action control of the cooling pipeline system, thereby providing guarantee for the safe and stable navigation of unmanned surface vessels.

[0005] The technical solution adopted by the present invention is as follows:

[0008] A signal is transmitted between the engine room control module and the cab control module, so that the engine room control module receives a control signal from the cab control module or the remote control station, and then controls the action of the cooling pipeline system through the engine room control module.

[0009] As a further improvement of the above technical solution:

[0010] The cab control module includes a first display and control unit and a boat-end information transmission unit, and the boat-end information transmission unit communicates wirelessly with the second display and control unit of the remote control station;

[0011] The engine room control module includes a main control unit, the main control unit is electrically connected to the first display and control unit to receive control signals from the cab control module. At the same time, the main control unit is electrically connected to the boat-end information transmission unit to receive control signals from the remote control station through the boat-end information transmission unit;

[0012] The main control unit is electrically connected to the sensor assembly in the cooling pipeline system through a first signal line to collect the pressure signal of the sensor assembly;

[0013] The main control unit is electrically connected to the remote control valve group in the cooling pipeline system through a second signal line to communicate with the remote control valve group, and then control the corresponding remote control valves in the remote control valve group to open or close, and receive the operation status feedback signal from the remote control valve group;

[0014] The main control unit is electrically connected to the cooling pump group in the cooling pipeline system through a third signal line to communicate with the cooling pump group, and then control the corresponding cooling pumps in the cooling pump group to start or stop, and receive the operation status feedback signal from the cooling pump group.

[0015] The main control unit communicates with the engine room monitoring and alarm system through a first serial port line, and the engine room monitoring and alarm system also transmits signals to the boat-end information transmission unit through a second serial port line, so that when the main control unit collects abnormal pressure signals, fault signals of the remote control valve group or fault signals of the cooling pump group, the engine room monitoring and alarm system issues an alarm signal.

[0016] The main control unit is electrically connected to the first display and control unit through a network cable.

[0017] The main control unit is electrically connected to the boat-end information transmission unit through a third serial port line.

[0018] A control method for a seawater cooling control system of an unmanned surface vessel based on the above, the control system has an automatic control mode and a manual control mode;

[0019] In the manual control mode, the operator in the cab sends a control signal to the main control unit through the first display and control unit to control the operation of the cooling pipeline system;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0037] As Figures 1 - 2 shown, an embodiment of the present application provides a seawater cooling control system for an unmanned surface vessel, including a cab control module arranged in the cab of the unmanned surface vessel. The cab control module communicates with a remote control station by wireless communication; and an engine room control module arranged in the engine room of the unmanned surface vessel. The engine room control module is electrically connected to a cooling pipeline system arranged in the engine room; a signal transmission is carried out between the engine room control module and the cab control module, so that the engine room control module receives a control signal from the cab control module or the remote control station, and then controls the operation of the cooling pipeline system through the engine room control module. By providing the cab control module and the engine room control module, precise control of the cooling pipeline system can be achieved when the unmanned surface vessel is in semi-autonomous or fully autonomous navigation. The control method is simple and efficient, thus effectively avoiding the adverse impact of communication delay on the operation control of the cooling pipeline system and providing guarantee for the safe and stable navigation of the unmanned surface vessel.

[0038] The cab control module includes a first display and control unit and a boat-end information transmission unit. The boat-end information transmission unit communicates wirelessly with the second display and control unit of the remote control station. Both the first display and control unit and the second display and control unit have the functions of sending control signals, displaying the corresponding system status, parameter setting, and data storage. The structures of the two display and control units are basically the same, and both are equipped with a human-machine interface. The opening and closing status of the remote control valve group in the cooling pipeline system, the operating status of the cooling pump group, and the pressure values at the inlet and outlet can be displayed on the interface. In addition, an audible and visual alarm can be issued when the outlet pressure value of the cooling pump group is lower than the set threshold. Moreover, the human-machine interface is in the form of a touch screen, and the operator can directly control each remote control valve in the remote control valve group and each cooling pump in the cooling pump group through the touch screen. The difference between the two is that a control conversion button is installed on the first display and control unit. Based on the interlock circuit, it can achieve the interlock between the remote control station and the cab control module, thus avoiding the main control unit receiving control signals from both parties simultaneously.

[0039] The engine room control module includes a main control unit. The main control unit is electrically connected to the first display and control unit to receive control signals from the cab control module. At the same time, the main control unit is electrically connected to the boat-end information transmission unit to receive control signals from the remote control station through the boat-end information transmission unit. The main control unit is electrically connected to the sensor assembly in the cooling pipeline system through the first signal line to collect the pressure signal of the sensor assembly. The main control unit is electrically connected to the remote control valve group in the cooling pipeline system through the second signal line to communicate with the remote control valve group, and then control the corresponding remote control valve in the remote control valve group to open or close, and receive the operation status feedback signal from the remote control valve group. The main control unit is electrically connected to the cooling pump group in the cooling pipeline system through the third signal line to communicate with the cooling pump group, and then control the corresponding cooling pump in the cooling pump group to start or stop, and receive the operation status feedback signal from the cooling pump group. By setting the main control unit, the automatic control mode and manual control mode of the control system can be realized. In the automatic control mode, the opening and closing status of the remote control valve group and the operation status of the cooling pump group can be automatically controlled based on the pre-stored control program without manual intervention. In the manual control mode, the operator in the cab or the remote control station controls the opening and closing status of the remote control valve group and the operation status of the cooling pump group.

[0040] In addition, in the automatic control mode, the control system has a normal seawater cooling working state and a standby seawater cooling working state; when in the normal seawater cooling working state, the main control unit automatically controls the main cooling water pump 9 and its related pipelines and remote control valve groups according to a preset program; when the main cooling water pump 9 fails, the main control unit automatically switches to the standby seawater cooling working state; when in the standby seawater cooling working state, the main control unit automatically controls the standby cooling water pump 10 and its related pipelines and remote control valve groups according to a preset program.

[0041] The main control unit is electrically connected to the first display and control unit through a network cable. Specifically, the main control unit and the first display and control unit communicate using the Ethernet protocol, which can effectively improve the data transmission speed and avoid the problem of delayed response of the main control unit.

[0042] The main control unit is electrically connected to the boat-end information transmission unit through a third serial cable. Through the boat-end information transmission unit, the control signals from the remote control station can be quickly and accurately transmitted to the main control unit.

[0043] The seawater cooling control system of the surface unmanned boat in this embodiment can also communicate with the engine room monitoring and alarm system. Specifically, the main control unit communicates with the engine room monitoring and alarm system through a first serial cable, and the engine room monitoring and alarm system also transmits signals to the boat-end information transmission unit through a second serial cable. Thus, when the main control unit collects abnormal pressure signals, the engine room monitoring and alarm system issues an alarm signal. The first signal line uses an RS485 serial cable, enabling the engine room monitoring and alarm system to quickly respond to the main control unit.

[0044] In both the manual control mode and the automatic control mode, when the main control unit monitors that the outlet pressure of the cooling pump group is lower than the threshold value, receives a fault signal from the remote control valve group, or receives a fault signal from the cooling pump group, it issues an alarm signal. When the first display and control unit receives this alarm signal, it issues an audible and visual alarm to remind the operator in the cab; or, when the alarm signal issued by the main control unit is sent to the boat-end signal transmission unit through the engine room monitoring and alarm system, the second display and control unit receives this alarm signal and issues an audible and visual alarm to remind the operator at the remote control station.

[0045] In this embodiment, the main control unit is used to execute control commands from the first display and control unit or the second display and control unit, and can collect the status signals of the cooling pipeline system; it is based on a PLC (Programmable Logic Controller) and integrates a relay component, and can control the remote control valve group and the cooling pump group, and can collect analog signals from the sensor component, the operation signals of the cooling pump group, and the status signals of the remote control valve group.

[0046] As Figure 3As shown in the figure, this embodiment provides a cooling pipeline system, including a first pipe group 11 connected to the first sea chest 7 and a second pipe group 12 connected to the second sea chest 8;

[0047] A main cooling water pump 9 is fitted and installed on the first pipe group 11. The end of the first pipe group 11 is connected to a cooling main pipe 16. The cooling main pipe 16 is respectively installed with a first branch pipe group 17 and a second branch pipe group 18. The main engine 1 and the gearbox 2 are successively connected on the first branch pipe group 17. The end of the first branch pipe group 17 is connected to a first drain pipe group 14. The end of the second branch pipe group 18 is connected to the cooling water inlet of the shaft seal device 4. The third branch pipe group 19 and the fourth branch pipe group 20 are also respectively installed on the second branch pipe group 18. The intermediate bearing 5 is connected on the third branch pipe group 19. The thrust bearing 6 is connected on the fourth branch pipe group 20. The ends of the third branch pipe group 19 and the fourth branch pipe group 20 are both connected to the second drain pipe group 15;

[0048] A standby cooling water pump 10 is fitted and installed on the second pipe group 12. The end of the second pipe group 12 is connected to the cooling main pipe 16. A connecting main pipe 13 is fitted and installed between the second pipe group 12 and the first pipe group 11;

[0049] In this embodiment, on the first pipe group 11, a filter 3, a first remote control valve, a second remote control valve, a first pressure sensor, and a second pressure sensor are successively fitted and installed between the first sea chest 7 and the main cooling water pump 9; among them, the first pressure sensor is used to monitor the pressure at the water inlet of the main cooling water pump 9, and the second pressure sensor is used to monitor the pressure at the water outlet of the main cooling water pump 9; the connection point of the connecting main pipe 13 and the first pipe group 11 is located between the first remote control valve and the second remote control valve;

[0050] On the second pipe group 12, another filter 3, a third remote control valve, a fourth remote control valve, a third pressure sensor, and a fourth pressure sensor are successively fitted and installed between the second sea chest 8 and the standby cooling water pump 10; among them, the third pressure sensor is used to monitor the pressure at the water inlet of the standby cooling water pump 10, and the fourth pressure sensor is used to monitor the pressure at the water outlet of the standby cooling water pump 10; the connection point of the connecting main pipe 13 and the second pipe group 12 is located between the third remote control valve and the fourth remote control valve;

[0051] On the first branch pipe group 17, a fifth remote control valve is fitted and installed at the cooling water inlet of the main engine 1;

[0052] On the second branch pipe group 18, a sixth remote control valve is fitted and installed at the cooling water inlet of the shaft seal device 4;

[0053] On the third branch pipe group 19, a seventh remote control valve is fitted and installed at the cooling water inlet of the intermediate bearing 5;

[0054] On the fourth pipe group 20, an eighth remote control valve is fitted at the cooling water inlet of the thrust bearing 6.

[0055] The main cooling water pump 9 and the standby cooling water pump 10 form a cooling pump group.

[0056] The first remote control valve, the second remote control valve, the third remote control valve, the fourth remote control valve, the fifth remote control valve, the sixth remote control valve, the seventh remote control valve and the eighth remote control valve form a remote control valve group.

[0057] The first pressure sensor, the second pressure sensor, the third pressure sensor and the fourth pressure sensor form a sensor assembly.

[0058] In the cooling pipeline system, according to specific usage requirements and installation requirements, each pipeline can be in the form of being spliced by several short pipes or in the form of a long pipe; in addition, a corresponding manual valve assembly is fitted on each pipeline, which is configured according to actual production requirements.

[0059] The remote control valves in the remote control valve group are all arranged at the water inlets of the corresponding cooling pumps and the corresponding equipment to be cooled; the control instructions for controlling the remote control valve group include opening the valve, closing the valve, stopping, resetting, and the status feedback is stopping in the middle, opening in place, closing in place, malfunction, opening, closing. The manual valves are all arranged at the water outlets of the corresponding cooling pumps and the corresponding equipment to be cooled, and when the unmanned surface vehicle is working, all the manual valves are in the normally open state, and the manual valves are mainly used for the cleaning and maintenance of the pipelines and equipment.

[0060] When the control system adopts the automatic control mode, the working process of the cooling pipeline system of this embodiment is as follows:

[0061] Initially, it adopts the normal seawater cooling working state, at this time the main cooling water pump 9 works and the standby cooling water pump 10 does not work.

[0062] The first remote control valve and the second remote control valve are in the open state, the third remote control valve and the fourth remote control valve are in the closed state, the first sea valve 7 is opened, and the external seawater enters the cooling main pipe 16 through the first pipe group 11.

[0063] The fifth remote control valve is opened, so that the seawater in the cooling main pipe 16 flows through the main engine 1 and the gearbox 2 in sequence through the first branch pipe group 17, thereby cooling the main engine 1 and the gearbox 2, and the cooled seawater is discharged outside through the first drain pipe group 14.

[0064] The sixth remote control valve is opened, so that the seawater in the cooling main pipe 16 flows through the shaft seal device 4 through the second branch pipe group 18, thereby cooling it, and the cooled seawater is directly discharged outside.

[0065] The seventh remotely controlled valve opens, allowing the seawater in the main cooling pipe 16 to flow through the second branch pipe group 18 and the third branch pipe group 19 in sequence and pass through the intermediate bearing 5, thereby cooling it. The cooled seawater is discharged outside through the second drain pipe group 15;

[0066] The eighth remotely controlled valve opens, allowing the seawater in the main cooling pipe 16 to flow through the second branch pipe group 18 and the fourth branch pipe group 20 in sequence and pass through the thrust bearing 6, thereby cooling it. The cooled seawater is discharged outside through the second drain pipe group 15;

[0067] The filter 3 on the first pipe group 11 filters the seawater entering the cooling pipeline system.

[0068] When the main cooling water pump 9 fails (that is, the pressure values monitored by the first pressure sensor and / or the second pressure sensor exceed their corresponding thresholds) or maintenance is required, it switches to the standby seawater cooling working state. At this time, the main cooling water pump 9 does not work, and the standby cooling water pump 10 works; the first remotely controlled valve and the second remotely controlled valve are in the closed state, the third remotely controlled valve and the fourth remotely controlled valve are in the open state, and the second submarine door 8 is opened. The external seawater enters the main cooling pipe 16 through the second pipe group 12, and the filter 3 on the second pipe group 12 filters the seawater entering the cooling pipeline system;

[0069] Under the standby seawater cooling working state, the cooling process of the subsequent equipment to be cooled is similar to that in the normal seawater cooling working state, which will not be elaborated here.

[0070] By setting the connecting main pipe 3, the first submarine door 7 and the second submarine door 8 can be connected, so that whether the control system works in the normal seawater cooling working state or the standby seawater cooling working state, the first submarine door 7 and the second submarine door 8 can provide seawater for the cooling pipeline system.

[0071] Based on the above seawater cooling control system of the surface unmanned boat, an embodiment of the present application provides a control method. The control system has an automatic control mode and a manual control mode;

[0072] In the manual control mode, the operator in the cab sends a control signal to the main control unit through the first display and control unit, thereby controlling the action of the cooling pipeline system; or, the operator in the remote control station sends a control signal to the unmanned boat through the second display and control unit, thereby controlling the action of the cooling pipeline system through the engine room control module, and then cooling the heating equipment components inside the unmanned boat;

[0073] The first display and control unit is configured with a control conversion button. Pressing the control conversion button sets the position, and pressing it again resets it;

[0074] When the control conversion button is reset, the signal transmission line between the first display and control unit and the main control unit is connected, while the signal transmission line between the boat-end information transmission unit and the main control unit is disconnected, so that the main control unit always receives the control signal from the first display and control unit;

[0075] When the control conversion button is set, the signal transmission line between the first display and control unit and the main control unit is disconnected, while the signal transmission line between the boat-end information transmission unit and the main control unit is connected, so that the main control unit always receives the control signal from the second display and control unit.

[0076] In the automatic control mode, the main control unit sends control signals to the remote control valve group and the cooling pump group respectively, so as to control the operation of the cooling pipeline system, and then cool the heating equipment components inside the unmanned boat;

[0077] The automatic control mode includes the normal seawater cooling working state and the standby seawater cooling working state;

[0078] In the normal seawater cooling working state, the main control unit sends control signals to the main cooling water pump in the cooling pump group and the corresponding remote control valve, so as to control the start of the main cooling water pump and the opening of the corresponding remote control valve, and then cool the heating equipment components inside the unmanned boat;

[0079] The main control unit collects the pressure data transmitted back by the sensor component in real time, so as to monitor the working state of the cooling pipeline system;

[0080] When the pressure value monitored by the second pressure sensor is lower than the first set threshold (10% of the rated head of the main cooling water pump 9), the main control unit obtains the state data of the main cooling water pump 9 and determines whether the main cooling water pump 9 is in the working state or the stopped state. The main control unit obtains the opening and closing state data of the first remote control valve, the second remote control valve, and the third remote control valve and determines whether the first remote control valve, the second remote control valve, and the third remote control valve are in the open state or the closed state, and transmits the state data back to the first display and control unit;

[0081] When the first display and control unit receives the transmitted signal indicating that the main cooling water pump 9 is in the working state and the first remote control valve, the second remote control valve, and the third remote control valve are all in the open state within the set time (5 s), it indicates that the working state of the main cooling water pump 9 is unstable and there may be a fault. In order to ensure the normal supply of cooling water to the mechanical equipment on the boat, the first display and control unit automatically issues an instruction to switch to the standby seawater cooling working state.

[0082] In the standby seawater cooling working state, the main control unit sends control signals to the standby cooling water pump in the cooling pump group and the corresponding remote control valve, so as to control the start of the standby cooling water pump and the opening of the corresponding remote control valve, and then cool the heating equipment components inside the unmanned boat;

[0083] A seawater cooling control system and control method for an unmanned surface vehicle of the present invention have an automatic control mode and a manual control mode. It can not only be controlled and monitored by the cab and the remote control station, but also can perform automatic control without manual intervention, simplify the control instructions of the remote control station, save the wireless communication data volume, shorten the response time of each device of the seawater cooling system, and improve the automation and intelligent level of the seawater cooling control system.
