[0061] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0062] The terms "first," "second," etc., used in the specification and claims are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0063] The fire prevention control system for harvesters provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0064] This application discloses a fire prevention control system for a harvester.

[0065] Figure 1 The first embodiment of this application provides a harvester fire prevention control system, comprising:

[0066] Image recognition device 2 is used to identify the fire status and debris area inside the delivery compartment of the harvester based on images inside the delivery compartment;

[0067] Temperature sensor 3 is used to detect the temperature inside the engine compartment of the harvester;

[0068] Temperature control device 4 is used to regulate the temperature of the engine compartment in the harvester.

[0069] The vehicle controller 1, connected to the image recognition device 2, temperature sensor 3, and temperature control device 4, is used to determine the impurity content in the engine compartment based on the area of ​​the debris and the outline area of ​​the preset fireproof zone when the fire situation is not yet under fire conditions, and to obtain the corresponding adjusted temperature; and

[0070] When the engine compartment temperature is higher than the set temperature, a temperature control signal is sent to the temperature control device 4 to adjust the engine compartment temperature to be lower than or equal to the set temperature.

[0071] Specifically, the image recognition device 2 is a camera. In this embodiment, the camera has infrared night vision capabilities, enabling it to capture and monitor images in low-light environments. In addition, the camera can analyze and process the images captured inside the transmitter cabin to identify the fire situation and the area of ​​debris.

[0072] The fire status indicates whether a fire has occurred in the engine compartment, and the debris area refers to the area occupied by crop stem and leaf fragments, fiber fluff, and other debris in the engine compartment. In this embodiment, after the image recognition device 2 captures an image of the engine compartment, it uses this image as input to a preset deep learning model to obtain the fire status output by the deep learning model.

[0073] Temperature sensor 3 collects the engine compartment temperature in real time and transmits the engine compartment temperature to vehicle controller 1. In this embodiment, the number of temperature sensors 3 can be one or two, and is not limited thereto.

[0074] The temperature control device 4 is a solenoid valve for the air conditioning vent located in the engine compartment of the harvester. It controls the amount of cold air by adjusting the size of the air conditioning vent, thereby achieving temperature regulation. It should be noted that in this embodiment, the air conditioning vent in the engine compartment is connected to the air conditioning system in the harvester's cab, and the air conditioning vent in the engine compartment is controlled by the solenoid valve for the air conditioning vent.

[0075] The vehicle controller 1 is electrically connected to the image recognition device 2, temperature sensor 3, and temperature control device 4. It is used to coordinate and control the image recognition device 2, temperature sensor 3, and temperature control device 4, and to perform real-time calculations and decisions based on preset logic and algorithms. The vehicle controller 1 is connected to the image recognition device 2 via a CAN (Controller Area Network) bus, the vehicle controller 1 is connected to the temperature sensor 3 via an analog input (Ai) circuit, and the vehicle controller 1 is connected to the temperature control device 4 via a pulse width modulation (PWM) signal.

[0076] When the fire situation is that no fire has occurred, the vehicle controller 1 determines the impurity content in the engine compartment based on the area of ​​debris and the outline area of ​​the preset fireproof zone, and obtains the corresponding adjustment temperature. The preset fireproof zone outline area is extracted from the engine compartment image using image recognition technology during the initial application or installation of the camera. It is easy to understand that the preset fireproof zone outline area is extracted during the initial camera calibration, while the debris area is obtained through subsequent image recognition of the engine compartment image.

[0077]

[0078] The set temperature refers to the safe temperature inside the engine compartment under different impurity levels; the higher the impurity level, the lower the set temperature. In this embodiment, the set temperature corresponding to each impurity level is preset, as shown in the table below:

[0079] Impurity ≤A1 A1≤x≤A2 A2≤x≤A3 …… An-1≤x≤An Adjusting the temperature T1 T2 T3 …… Tn

[0080] Among them, An>……>A3>A2>A1>0.

[0081] When the engine compartment temperature is higher than the set temperature, the vehicle controller 1 sends a temperature adjustment signal to the temperature control device 4, causing the temperature control device 4 to adjust the engine compartment temperature to be lower than or equal to the set temperature. It is easy to understand that when the impurity content is in the range of (A1, A2), the temperature control device 4 needs to control the engine compartment temperature to be lower than or equal to T2.

[0082] Figure 2 The second embodiment of the harvester fire prevention control system provided in this application, compared with the vehicle controller 1, image recognition device 2, temperature sensor 3 and temperature control device 4 in the first embodiment, further includes:

[0083] The speed control device 5 is electrically connected to the vehicle controller 1 and is used to control the harvester to decelerate to a speed less than or equal to the first preset speed when the temperature in the engine compartment is greater than the regulated temperature.

[0084] Specifically, the vehicle controller 1 is connected to the speed control device 5 via a circuit. The speed control device 5 is a solenoid valve for the travel electronic oil pump, which is used to control the speed of the harvester by controlling the discharge of the electronic oil pump.

[0085] When the engine compartment temperature is higher than the set temperature, the harvester is slowed down to a speed less than or equal to the first preset speed. This helps to prevent mechanical parts from malfunctioning or being damaged when the engine compartment temperature is too high. At the same time, slowing down the harvester when the mechanical parts are unstable under high temperature conditions also effectively ensures the safety of the driver.

[0086] When the fire situation is not in progress and the harvester is in operation, the speed control device 5 is used to control the harvester to decelerate to a speed less than or equal to the second preset speed; when the fire situation is not in progress and the harvester is not in operation, the speed control device 5 is used to control the harvester to decelerate to a speed less than or equal to the third preset speed.

[0087] Specifically, when the fire situation is that a fire has occurred and the harvester is in operation, in order to prevent the fire from spreading, the vehicle controller 1 controls the temperature control device 4 to shut down.

[0088] In the event of a fire that has not yet started, to prevent the fire from spreading, the temperature control device 4 must be shut off. Simultaneously, when the harvester is in operation, the harvester should be slowed to a speed less than or equal to the second preset speed; when the harvester is not in operation, the harvester should be slowed to a speed less than or equal to the third preset speed, effectively ensuring the driver's safety. It should be noted that in this embodiment, the second and third preset speeds are less than the first preset speed. The values ​​of the second and third preset speeds can be the same or different; this is not limited here.

[0089] In this embodiment, the speed control device 5 is further used for:

[0090] After the harvester decelerates to a speed less than or equal to a second preset speed and travels for a preset first time, the speed of the harvester is controlled to be 0; after the harvester decelerates to a speed less than or equal to a third preset speed and travels for a preset second time, the speed of the harvester is controlled to be 0.

[0091] The preset first duration and the preset second duration can be the same or different, and no limitation is made here.

[0092] If the fire on the harvester is not yet a fire, first slow down the harvester, and then reduce the speed to 0 after a preset time. This helps reduce friction and heat generation in the harvester, which helps control the spread of the fire. At the same time, it reduces the operating time of the equipment, lowers the possibility of equipment damage, and effectively ensures the safety of the operator.

[0093] Optionally, this application embodiment also includes a fire extinguishing device 6, which is electrically connected to the vehicle controller 1, and is used to activate the solenoid valve of the fire extinguishing device 6 to extinguish the fire in the engine compartment when the fire situation is not a fire.

[0094] Specifically, the vehicle controller 1 is connected to the solenoid valve of the fire extinguishing device 6 via a circuit. The fire extinguishing device 6 can be a CO2 fire extinguisher, a dry powder fire extinguisher, etc., and is not limited here. In this embodiment, the fire extinguishing device 6 is installed on the chassis of the harvester, and the pipeline of the fire extinguishing device 6 is introduced into the engine compartment so that when a fire occurs in the engine compartment, the fire extinguishing agent can be delivered to the engine compartment to extinguish the fire. The fire extinguishing device 6 is controlled by the solenoid valve of the fire extinguishing device 6. It is easy to understand that when a fire occurs in the engine compartment, the fire extinguishing device 6 can be controlled by controlling the solenoid valve of the fire extinguishing device 6. When fire extinguishing is needed, the solenoid valve of the fire extinguishing device 6 is opened, allowing the fire extinguishing agent to flow into the engine compartment to extinguish the fire; when the fire is under control or fire extinguishing needs to be stopped, the solenoid valve is closed to stop the supply of fire extinguishing agent.

[0095] Optionally, embodiments of this application also include:

[0096] The display screen 7 is connected to both the vehicle controller 1 and the image recognition device 2, and is used to display the fire status, engine compartment temperature and impurity content.

[0097] The warning device 8 is electrically connected to the vehicle controller 1 and is used to issue a warning signal when the engine compartment temperature is higher than the regulated temperature and / or when a fire has occurred.

[0098] Specifically, in this embodiment, the warning device 8 refers to a buzzer. The display screen 7 is connected to the vehicle controller 1 via a CAN bus, the image recognition device 2 is connected to the display screen 7 via a circuit, and the vehicle controller 1 is connected to the output port of the warning device 8 via a circuit. The vehicle controller 1 transmits the fire status, engine compartment temperature, and impurity content to the display screen 7 in real time via the CAN bus. The display screen 7 displays the fire status, engine compartment temperature, and impurity content in real time. The operator can view the scene inside the engine compartment on the display screen 7 and observe the situation inside the engine compartment.

[0099] The fire prevention control system for the harvester provided in this embodiment includes an image recognition device 2 for accurate detection and identification of the fire status and debris area in the harvester's engine compartment, which helps to promptly identify potential fire hazards. A temperature sensor 3 and a temperature control device 4 are used to monitor and adjust the engine compartment temperature in real time, ensuring it remains within a safe range and effectively preventing overheating and subsequent fires. The vehicle controller 1 determines the impurity content in the engine compartment based on the debris area and the outline area of ​​the preset fire prevention zone, facilitating monitoring of this content. When the engine compartment temperature exceeds the set temperature, the temperature control device 4 adjusts it to be less than or equal to the set temperature, effectively ensuring the engine compartment temperature remains within a safe range and preventing overheating and subsequent fires. By monitoring the fire status and impurity content in the harvester's engine compartment and promptly adjusting it to be less than or equal to the set temperature when it exceeds the set temperature, the system effectively prevents and controls fires, improving the safety of the harvester.

[0100] This application also discloses a harvester, including a harvester fire prevention control system as described in the above embodiments.

[0101] Reference Figure 3 This application also discloses a fire prevention control method for a harvester, comprising:

[0102] S110: Real-time acquisition of the engine compartment temperature inside the harvester's engine compartment.

[0103] In this embodiment, a temperature sensor is used to obtain the engine compartment temperature in the harvester in real time.

[0104] S120. Based on image recognition inside the engine compartment, the area of ​​debris and the fire status inside the engine compartment are obtained.

[0105] The fire status is used to indicate whether a fire has occurred in the engine compartment. Specifically, the fire status includes two states: fire occurred and no fire occurred. In this embodiment, images of the engine compartment are first acquired using a camera pre-installed in the engine compartment, and image recognition is performed on the images of the engine compartment to obtain the area of ​​debris and the fire status in the engine compartment.

[0106] S130. When the fire situation is that no fire has occurred, the impurity content in the engine compartment is determined based on the area of ​​the debris and the outline area of ​​the preset fire prevention zone.

[0107] Impurity rate is used to indicate the probability of debris in the engine compartment. A higher impurity rate indicates a higher risk of fire.

[0108] S140, Obtain the adjustment temperature corresponding to the impurity content.

[0109] Regulated temperature refers to the safe temperature inside the engine compartment under different impurity levels; the higher the impurity level, the lower the regulated temperature.

[0110] S150. When the engine compartment temperature is higher than the set temperature, adjust the engine compartment temperature to be lower than or equal to the set temperature.

[0111] In practice, the temperature of the engine compartment is regulated by a temperature control device, specifically an air conditioning vent solenoid valve. First, a temperature regulation signal is sent to the air conditioning vent solenoid valve, which then regulates the temperature of the engine compartment to be less than or equal to the regulated temperature.

[0112] Excessive engine compartment temperature can increase the risk of fire in the engine compartment of a harvester. By adjusting the solenoid valve of the air conditioning vent, the engine compartment temperature can be kept within a safe range, thereby effectively reducing the risk of fire and protecting the safety of equipment and personnel.

[0113] If the engine compartment temperature is higher than the set temperature, the engine compartment temperature should be adjusted to be lower than or equal to the set temperature to reduce the risk of fire.

[0114] The fire prevention and control method for harvesters provided in this embodiment adjusts the engine compartment temperature to be less than or equal to the set temperature when the temperature in the engine compartment exceeds the set temperature. This effectively ensures that the engine compartment temperature remains within a safe range, preventing overheating and potential fires. By monitoring the fire situation and impurity content within the harvester's engine compartment, and promptly adjusting the engine compartment temperature to be less than or equal to the set temperature when it exceeds the set temperature, the method effectively prevents and controls fires, improving the safety of the harvester.

[0115] In one embodiment of this invention, the fire prevention control method for harvesters further includes the following steps:

[0116] S210. When the temperature in the engine compartment is higher than the set temperature, control the harvester to decelerate to a speed less than or equal to the first preset speed.

[0117] In this embodiment, when the engine compartment temperature is higher than the set temperature, the engine compartment temperature is adjusted to be lower than or equal to the set temperature. At the same time, the harvester is controlled to decelerate to a speed lower than or equal to the first preset speed. This allows the harvester to be decelerated when the engine compartment temperature is too high, thereby effectively preventing mechanical component failure or damage. In addition, decelerating the harvester when the mechanical components are unstable under high temperature conditions also effectively ensures the safety of the driver.

[0118] In one embodiment of this invention, the fire prevention control method for harvesters further includes the following steps:

[0119] S310. When a fire has occurred and the harvester is in operation, control the harvester to decelerate to a speed less than or equal to the second preset speed.

[0120] S320. When a fire has occurred and the harvester is not in operation, control the harvester to decelerate to a speed less than or equal to the third preset speed.

[0121] When a fire has occurred and the harvester is in operation, the harvester is controlled to decelerate to a speed less than or equal to a second preset speed. When the harvester is not in operation, the harvester is controlled to decelerate to a speed less than or equal to a third preset speed. This deceleration helps reduce heat generation in the engine compartment and effectively ensures operator safety. Specifically, the second and third preset speeds can be the same or different.

[0122] In one embodiment of this invention, the engine compartment temperature is regulated by a temperature control device, and the harvester fire prevention control method further includes:

[0123] S410. When a fire has occurred and the harvester is in operation, the temperature control device shall be shut down.

[0124] When a fire has occurred and the harvester is in operation, in order to effectively control the fire, the temperature control device needs to be turned off to stop the temperature regulation of the engine compartment. Specifically, in this embodiment, the temperature control device is an air conditioning vent solenoid valve.

[0125] In one embodiment of this invention, after controlling the harvester to decelerate to a speed less than or equal to a second preset speed, the following steps are included:

[0126] S510. After the harvester has traveled for a preset first time, control the harvester speed to 0.

[0127] After controlling the harvester to decelerate to a speed less than or equal to a third preset speed, the following steps are included:

[0128] S520: After the harvester has traveled for a preset second duration, control the harvester's speed to 0.

[0129] After the harvester decelerates to a speed less than or equal to a second preset speed, and after traveling for a preset first duration, the harvester's speed is controlled to 0, i.e., the harvester is stopped. Similarly, after the harvester decelerates to a speed less than or equal to a third preset speed, and after traveling for a preset second duration, the harvester's speed is controlled to 0, i.e., the harvester is stopped. This effectively ensures that the harvester will not continue to operate under fire conditions, reducing further fire risk. The first and second durations can be the same or different.

[0130] In one embodiment of this invention, the fire prevention control method for harvesters further includes the following steps:

[0131] S610. In the event that a fire has not yet occurred, control the fire extinguishing device to extinguish the fire inside the engine compartment.

[0132] In this embodiment, the fire extinguishing device can be a CO2 fire extinguisher, a dry powder fire extinguisher, etc., and is not limited thereto. If a fire occurs in the engine compartment, the fire extinguishing device will be controlled to extinguish the fire in the engine compartment.

[0133] In one embodiment of this invention, the fire prevention control method for harvesters further includes the following steps:

[0134] S710 displays fire status, cabin temperature, and impurity content.

[0135] S720 issues a warning signal when the cabin temperature exceeds the regulated temperature and / or when a fire is not yet present.

[0136] By displaying the fire status, engine compartment temperature, and impurity content, it provides real-time monitoring and information feedback, enabling operators to promptly understand the current fire situation, engine compartment temperature, and changes in impurity content within the engine compartment. Simultaneously, when the engine compartment temperature exceeds the set temperature or a fire occurs, it issues an early warning signal to alert the operator to the presence of a fire or abnormal engine compartment temperature, allowing them to take appropriate measures to prevent further fire hazards.

[0137] In one embodiment of this invention, the fire situation in the engine compartment is determined based on image recognition within the engine compartment, including the following steps:

[0138] S121. Input the image inside the engine compartment into the preset deep learning model to obtain the fire status inside the engine compartment of the harvester.

[0139] In this embodiment, the deep learning model is first trained based on smoke and flame images. The trained deep learning model is the preset deep learning model. By inputting the image inside the engine compartment into the preset deep learning model, the fire status inside the engine compartment of the harvester can be obtained.

[0140] The fire status is obtained by inputting images of the engine compartment into a preset deep learning model, effectively ensuring the accuracy of fire status identification.

[0141] In one embodiment of this invention, the impurity content in the engine compartment is determined based on the area of ​​the debris and the outline area of ​​the preset fireproof zone, including the following steps:

[0142] S131. The value obtained by dividing the area of ​​debris by the area of ​​the preset fireproof zone outline is used as the debris content rate in the engine compartment.

[0143] The method for calculating the impurity content has been introduced above and will not be repeated here.

[0144] By calculating the impurity content rate, it is easy to assess the ratio between the area of ​​debris in the engine compartment and the outline area of ​​the pre-set fire prevention zone. In turn, the impurity content rate can be used to determine the risk of fire and facilitate a preliminary assessment of fire risk.

[0145] This application also discloses a machine-readable storage medium, which stores a computer program, wherein when the computer program is executed by a processor, it employs the harvester fire prevention control method described in the above embodiments.

[0146] The computer program can be stored in a machine-readable medium. The computer program includes computer program code, which can be in the form of source code, object code, executable file, or certain middleware.
