[0030] In order to make the purpose, technical solutions and advantages of the application more clear, the application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0031] Please refer to Figure 1 , Figure 1 A method implementation flowchart of a remote fire extinguishing method for an unmanned ship engine room is provided for the embodiments of the application. As shown in Figure 1 , it can specifically include steps S11 to S13.

[0032] S11: In the case of determining that the unmanned ship engine room is on fire, send a shutdown instruction to the ventilation equipment in the unmanned ship engine room and a speed reduction idle machine instruction to the main engine equipment in the unmanned ship engine room, control the ventilation equipment to enter the shutdown state and control the main engine equipment to enter the speed reduction idle state.

[0033] In this embodiment, a network communication link is established between the shore-based command center and the unmanned ship, which is used to realize the interaction between the shore-based command center and various devices in the unmanned ship. The shore-based command center can remotely monitor the unmanned ship when the unmanned ship is performing a cruising task, determine whether there is a fire in the engine room of the unmanned ship, and control the unmanned ship to automatically extinguish the fire and return to the shore-based command center when it is determined that there is a fire in the engine room of the unmanned ship. In this embodiment, when the shore-based personnel of the shore-based command center determines that there is a fire in the engine room of the unmanned ship which is performing a cruising task, a shutdown instruction is sent to the ventilation device in the engine room of the unmanned ship through the network communication link. The ventilation device in the engine room of the unmanned ship enters a shutdown state in response to the shutdown instruction after receiving the shutdown instruction. At the same time, a reduced-speed idle instruction is sent to the main engine device in the engine room of the unmanned ship through the network communication link. The main engine device in the engine room of the unmanned ship enters a reduced-speed idle state in response to the reduced-speed idle instruction after receiving the reduced-speed idle instruction, and then the main engine device is shut down. The main engine device is restarted in the fastest way through the idle to the shutdown. Based on this, the ventilation device in the engine room of the unmanned ship can be remotely controlled to enter the shutdown state, and the main engine device in the engine room of the unmanned ship can be remotely controlled to enter the reduced-speed idle state. In this embodiment, the ventilation device includes a fan and a damper, wherein the damper is the air inlet and the air outlet of the engine room of the unmanned ship.

[0034] S12: In a case where it is determined that the ventilation device has entered the shutdown state and the main engine device has entered the reduced-speed idle state, a fire extinguishing instruction is sent to the automatic fire extinguisher in the engine room of the unmanned ship to control the automatic fire extinguisher to perform a fire extinguishing operation.

[0035] In this embodiment, after the shore-based command center sends the shutdown instruction to the ventilation device in the engine room of the unmanned ship and the reduced-speed idle instruction to the main engine device in the engine room of the unmanned ship, the shore-based command center waits for the ventilation device in the engine room of the unmanned ship to feed back a corresponding response instruction and waits for the main engine device to feed back a corresponding response instruction. After receiving the response instructions of the ventilation device and the main engine device, it can be determined whether the ventilation device has entered the shutdown state and whether the main engine device has entered the reduced-speed idle state according to the response instructions. In a case where it is determined that the ventilation device has entered the shutdown state and the main engine device has entered the reduced-speed idle state, a fire extinguishing instruction is further sent to the automatic fire extinguisher in the engine room of the unmanned ship. The automatic fire extinguisher in the engine room of the unmanned ship performs a corresponding fire extinguishing operation in response to the fire extinguishing instruction after receiving the fire extinguishing instruction. Based on this, the automatic fire extinguisher in the engine room of the unmanned ship can be remotely controlled to perform a corresponding fire extinguishing operation, so as to extinguish the fire in the engine room of the unmanned ship. Exemplarily, the automatic fire extinguisher in the engine room of the unmanned ship includes but is not limited to a dry powder fire extinguisher, a carbon dioxide fire extinguisher, a foam fire extinguisher, etc.

[0036] As can be seen from the above, the remote fire extinguishing method of the unmanned ship engine room provided by the embodiments of the present application can realize that the shore-based personnel remotely confirms whether the unmanned ship engine room is on fire and remotely extinguishes the fire through instruction control during the execution of the cruising task of the unmanned ship. Moreover, by controlling the ventilation equipment to enter the shutdown state and the main engine equipment to enter the reduced speed idle state before the execution of the fire extinguishing operation, the damage of the equipment in the unmanned ship engine room can be avoided, and the safety of the equipment in the unmanned ship can be ensured.

[0037] In some embodiments of the present application, please refer to Figure 2 , Figure 2 The flow chart of a method for determining that the unmanned ship is on fire in the remote fire extinguishing method of the unmanned ship engine room provided by the embodiments of the present application. As shown in Figure 2 , the method can specifically include steps S21 to S25.

[0038] S21: receiving a first temperature and humidity value of the unmanned ship engine room;

[0039] S22: judging whether the temperature and humidity of the unmanned ship engine room is abnormal according to the historical record according to the first temperature and humidity value;

[0040] S23: in the case that the temperature and humidity of the unmanned ship engine room is abnormal, sending a video acquisition instruction to a camera device in the unmanned ship engine room and receiving a video image uploaded by the camera device;

[0041] S24: judging whether there is smoke in the unmanned ship engine room and judging whether a smoke sensor in the unmanned ship engine room is lighted according to the video image;

[0042] S25: in the case that it is determined that there is smoke in the unmanned ship engine room and the smoke sensor is lighted, determining that the unmanned ship engine room is on fire.

[0043] In the embodiment, the unmanned ship cabin is provided with a temperature and humidity sensor for detecting the temperature and humidity information in the unmanned ship cabin. The temperature and humidity information detected by the temperature and humidity sensor is fed back to the shore-based command center in real time, and the temperature and humidity in the cabin is monitored by the shore-based command center in real time. It can be understood that the pre-stored cabin temperature and humidity curve is a temperature and humidity curve drawn according to the temperature and humidity information corresponding to each cruise stage when the unmanned ship normally performs the cruise task in the historical execution of the cruise task, which is the temperature and humidity data when the unmanned ship normally performs the cruise task. In the embodiment, after the shore-based command center receives the first temperature and humidity value of the unmanned ship cabin, the first temperature and humidity value can be compared with the pre-stored cabin temperature and humidity curve by comparing the first temperature and humidity value with the pre-stored cabin temperature and humidity curve. If it is not within the required range of the cabin temperature and humidity curve, it can be determined that the temperature and humidity of the unmanned ship cabin is abnormal. The camera equipment for monitoring the cabin environment is installed in the unmanned ship cabin. The shore-based command center further sends a video acquisition instruction to the camera equipment in the unmanned ship cabin when it is determined that the temperature and humidity of the unmanned ship cabin is abnormal. The camera equipment acquires the video image of the cabin by responding to the video acquisition instruction, and uploads the video image to the shore-based command center.

[0044] In a specific embodiment, after the shore-based command center receives the video image, the shore-based personnel can observe the video image to determine whether there is smoke in the unmanned ship cabin. The unmanned ship cabin is also provided with a smoke sensor. When the smoke concentration in the unmanned ship cabin reaches a certain concentration threshold, the warning light built in the smoke sensor will light up. The shore-based personnel can determine whether the smoke sensor is on by observing the video image taken by the camera equipment containing the position of the smoke sensor. The shore-based personnel determine whether the unmanned ship cabin is on fire according to whether there is smoke in the unmanned ship cabin and whether the smoke sensor is on. If the shore-based personnel determines that there is smoke in the unmanned ship cabin and the smoke sensor is on by observing the video image, it can be determined that the unmanned ship cabin is on fire.

[0045] In a specific embodiment, whether there is smoke in the unmanned ship cabin and whether the smoke sensor in the unmanned ship cabin is on can be determined by training a neural network model. For example, a smoke detection model and a smoke sensor state detection model can be pre-trained. After the shore-based command center receives the video image, the video image can be input into the smoke detection model and the smoke sensor state detection model for detection, so as to determine whether there is smoke in the unmanned ship cabin and whether the smoke sensor in the unmanned ship cabin is on according to the video image. Both the smoke detection model and the smoke sensor state detection model are convolutional neural network models trained to a convergent state. Specifically, the convolutional neural network model can be a CNN convolutional neural network model or a VGG convolutional neural network model. It can be understood that the smoke detection model is obtained by training the convolutional neural network model to a convergent state using a large number of environmental images under different smoke concentration scenarios as sample data, and the smoke detection model has the ability to identify whether there is smoke in the video image. The smoke sensor state detection model is obtained by training the convolutional neural network model to a convergent state using a large number of images under the on state and the off state of the smoke sensor as sample data, and the smoke sensor state detection model has the ability to identify whether the smoke sensor in the video image is on.

[0046] In an embodiment of the present application, when a fire occurs, smoke first appears at the location where the fire occurs, and there can be a monitoring dead angle in the unmanned ship cabin. When a fire occurs, the camera equipment may not capture the location of the fire, so that the video image captured by the camera equipment has no smoke, and the video image reflects an inaccurate smoke condition. In this embodiment, if the shore-based command center determines that there is no smoke in the unmanned ship cabin according to the current obtained video image when the temperature and humidity in the unmanned ship cabin are abnormal, the camera equipment in the unmanned ship cabin can be sent a device view angle adjustment instruction, and the device view angle adjustment instruction includes an adjustment angle of the view angle of the camera equipment. The camera equipment is controlled to adjust the angle according to the adjustment angle, so that the camera equipment obtains a video image under another view angle, and the video image under the other view angle is re-uploaded to the shore-based command center. The shore-based command center further determines whether there is smoke in the unmanned ship cabin and whether the smoke sensor is on according to the re-received video image until it is determined that there is smoke in the unmanned ship cabin and the smoke sensor is on.

[0047] In an embodiment of the present application, please refer to Figure 3 , Figure 3 A method for recovering the working state of the ventilation equipment and the main engine equipment in the remote fire extinguishing method of the unmanned ship cabin provided in the embodiment of the present application is shown in a flowchart. As shown in Figure 3 , the method can specifically include steps S31 to S33.

[0048] S31: In the case where the fire extinguishing operation is completed, a second temperature and humidity value and a smoke concentration value of the unmanned ship cabin are obtained;

[0049] S32: According to the second temperature and humidity value and the smoke concentration value, it is judged whether the environment in the unmanned ship cabin meets the equipment state recovery condition;

[0050] S33: In the case where the environment in the unmanned ship cabin meets the equipment state recovery condition, a state recovery instruction is sent to the ventilation equipment and the main engine equipment in the unmanned ship cabin, and the ventilation equipment and the main engine equipment are controlled to perform the start-up process.

[0051] In the embodiment, the temperature and humidity and the smoke concentration of the site environment of the unmanned ship cabin cannot be restored to the environment capable of normal work immediately after the fire is extinguished. In the embodiment, whether the ventilation equipment and the main engine equipment are controlled to be restored to the state of start-up work can be determined according to the environment of the unmanned ship cabin after the fire extinguishing operation. For example, after the fire extinguishing operation is completed, the second temperature and humidity value and the smoke concentration value of the unmanned ship cabin are obtained. Further, the second temperature and humidity value is compared with the preset temperature and humidity threshold value, and the smoke concentration value is compared with the preset smoke concentration value, so as to judge whether the environment in the unmanned ship cabin meets the equipment state recovery condition according to the obtained second temperature and humidity value and smoke concentration value. Specifically, when the second temperature and humidity value is lower than the preset temperature and humidity threshold value and the smoke concentration value is lower than the preset concentration threshold value, it is judged that the environment in the unmanned ship cabin meets the equipment state recovery condition. In the case where the environment in the unmanned ship cabin meets the equipment state recovery condition, the state recovery instruction is sent to the ventilation equipment and the main engine equipment in the unmanned ship cabin, and the ventilation equipment and the main engine equipment are controlled to perform the start-up process, so as to restore the normal working state of the ventilation equipment and the main engine equipment in the unmanned ship cabin, and facilitate the autonomous return of the unmanned ship.

[0052] In some embodiments of the present application, after the automatic fire extinguisher is controlled to extinguish the fire of the unmanned ship cabin, the unmanned ship can send warning information to the shore-based command center, and the side light, the warning light, and the horn in the unmanned ship can play a prompt sound, so as to display the real-time state of the unmanned ship. In the embodiment, after the automatic fire extinguisher is controlled to extinguish the fire of the unmanned ship cabin, the state monitoring instruction can also be sent to the unmanned ship, the state monitoring instruction triggers the sending of the warning information to the shore-based command center, so that the shore-based command center can determine the real-time state of the unmanned ship during the fire extinguishing. It can be understood that the real-time state information includes the side light state information, the warning light state information, and the unmanned ship positioning information of the unmanned ship.

[0053] It can be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
