Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of fire-fighting equipment control, and more specifically, relates to a control method, a control device, a control equipment, and a computer-readable storage medium for a fire-fighting cannon. Background Art
[0002] In the prior art, fire monitors are key components of fire protection systems in converter stations and large substations. Currently, fire monitors are mainly controlled in two ways: semi-automatic control and manual control.
[0003] In the semi-automatic control mode, multiple preset positions are set in advance based on past firefighting experience. When a fire is discovered and confirmed, the staff needs to quickly press the corresponding preset switch or button according to the location of the fire, so that the fire monitor can quickly adjust its spray position, and then start the fire monitor to extinguish the fire. In the manual control mode, after the staff discovers and confirms the fire, they manually adjust the position of the fire monitor to the spray position according to the location of the fire, and then start the fire monitor to extinguish the fire.
[0004] However, both the semi-automatic control method and the manual control method have an obvious defect, that is, after confirming the need for fire extinguishing, the cannon head needs to be adjusted to the corresponding position before starting the spraying, which takes a long time. When a fire occurs, time is life. This time delay may cause the fire to spread and expand, causing more serious damage to equipment and buildings in places such as converter stations and large substations, and thus bring huge economic losses and safety hazards. Therefore, there is an urgent need for a more efficient and faster response fire cannon control method to improve fire extinguishing efficiency and reduce fire losses.

[0040] The purpose of this application is to provide a control method, a control device, a control equipment, and a computer-readable storage medium for a fire monitor to improve the fire extinguishing efficiency of the fire monitor and reduce fire losses.
[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0042] The following is an example of an embodiment to illustrate a method for controlling a fire monitor provided by the present application.
[0043] Please refer to Figure 1 , Figure 1 A flow chart of a method for controlling a fire monitor provided in an embodiment of the present application.
[0044] In this embodiment, the method may include:
[0045] S101, when a fire signal is received, the control device acquires environmental image data through an image acquisition device;
[0046] The reception of the fire signal in this step is the trigger condition for starting the entire fire monitor control process. When the fire detectors in the fire protection system (such as smoke detectors, temperature detectors, etc.) detect that the fire-related characteristics reach the preset threshold, a fire signal will be issued. After receiving the signal, the control device immediately starts the image acquisition device to obtain environmental image data. The image acquisition device can be a high-definition camera, infrared thermal imager, etc., which can image the fire scene environment from different angles and methods, and provide basic data for the subsequent determination of the ignition point.
[0047] In the hardware architecture of the fire protection system, the fire detector is connected to the control device through wired or wireless communication. When the fire detector detects a fire signal, it transmits the signal to the control device. The control device is pre-set with corresponding program instructions. Once a fire signal is received, it will send a start signal to the image acquisition device connected to it, and the image acquisition device will start working to obtain environmental image data. For example, a high-definition camera will take visible light images of the fire scene to capture visual information of flames, smoke, and the surrounding environment; an infrared thermal imager will generate infrared images based on the temperature difference of objects to highlight high-temperature areas, and these image data will be transmitted back to the control device in real time.
[0048] In this step, the rapid acquisition of environmental image data helps to grasp the actual situation of the fire scene in a timely manner, providing a key source of information for the subsequent accurate capture of the location of the fire point. Compared with the traditional fire monitor control method, which may require manual on-site observation of the fire and then manual operation, this automated data acquisition method greatly saves time and can respond more quickly in the early stages of a fire, thereby buying precious time for effective fire control and reducing the losses that may be caused by the fire.
[0049] S102, performing fire point capture processing based on the environmental image data to obtain fire point position data;
[0050] Based on S101, this step aims to capture the fire point using different technical means according to the acquired environmental image data type (such as environmental high-definition photo data or infrared image data). For environmental high-definition photo data, fire feature detection is performed based on fire feature data (including flame feature data, smoke feature data, combustion feature data) and a pre-trained image detection model to determine the fire feature area; for infrared image data, high temperature points are identified based on temperature recognition features, and then the high temperature area is determined. By positioning these feature areas or high temperature areas, the fire point location data is finally obtained.
[0051] When the environmental image data is environmental high-definition photo data: the control device stores fire characteristic data, which includes information such as the color, shape, and movement characteristics of the flame, the concentration, color, and diffusion characteristics of the smoke, and the appearance change characteristics of the burning material. At the same time, the image detection model is trained through a large amount of image data with fire characteristic annotations. The acquired environmental high-definition photo data is input into the image detection model. The model will analyze and compare each pixel or area in the photo according to the fire characteristic data, and detect the area that meets the fire characteristics, that is, the fire characteristic area. Then, through the positioning processing technology such as geometric analysis and coordinate calculation of the fire characteristic area, the location data of the fire point is determined, such as the coordinates of the fire point in the image or the actual spatial position coordinates relative to the fire cannon system.
[0052] When the environmental image data is infrared image data: the infrared image data reflects the temperature distribution of objects in the scene. The control device uses the temperature recognition feature to set a temperature threshold and recognizes the area in the image with a temperature higher than the threshold as a high-temperature area. Then, by analyzing and calculating the position of the high-temperature area, the ignition point position data, such as the center position coordinates of the high-temperature area, is obtained.
[0053] In this step, this fire point capture processing method can quickly and accurately determine the location of the fire point, avoiding the errors and delays that may occur in manual search for the fire point. In a complex fire scene environment, whether it is day or night, whether the flame is obvious or obscured, the fire point can be effectively located through intelligent analysis of image data. This provides a reliable basis for fire monitors to accurately point to the fire point for fire extinguishing, greatly improving the accuracy and efficiency of fire extinguishing, helping to quickly control the fire and reduce the damage of the fire to the surrounding environment and equipment.
[0054] S103, matching the corresponding fire monitor based on the fire point location data, and starting the fire monitor;
[0055] Based on S102, in this step, the fire monitor closest to the fire point is found in the layout of the fire monitor system according to the calculated fire point location data. This is achieved based on the location information of each fire monitor pre-stored in the fire monitor system and the spatial distance calculation with the fire point location data. After finding the nearest fire monitor, the control device sends a start signal to it to put the fire monitor into working state.
[0056] In this step, the control device saves the installation location information of all fire monitors, including its coordinates in space and other parameters. After obtaining the location data of the ignition point, the distance between each fire monitor and the ignition point is calculated by a distance calculation formula (such as the Euclidean distance formula, etc.). Then compare these distance values to determine the nearest fire monitor. Once determined, the control device sends a start command to the drive device of the fire monitor through a communication line (wired or wireless). After receiving the command, the drive device starts the motor, hydraulic system and other components of the fire monitor, so that the fire monitor rotates from the initial position and adjusts the muzzle direction to aim at the ignition point.
[0057] In this step, the fire monitor closest to the fire point is quickly matched and activated, which can minimize the time it takes for the fire monitor to reach the fire point and achieve rapid response to fire extinguishing. Compared with the traditional method of manually judging and manually selecting fire monitors, this automated matching and activation method saves a lot of time, improves the timeliness of fire extinguishing, and effectively prevents the fire from spreading further while waiting for the fire monitor to be activated and adjusted, thereby reducing fire losses.
[0058] S104, control the fire monitor to extinguish the fire.
[0059] Based on S103, after the fire monitor is started and aimed at the fire point, this step controls the spray angle and water output of the fire monitor according to the preset fire extinguishing parameters to achieve the best fire extinguishing effect. The preset angle and water output are set based on comprehensive consideration of various factors such as different types of fires, different fire scenes, and fire monitor performance.
[0060] The control device in this step stores preset fire-fighting schemes for different fire situations, including parameters such as preset angles and preset water output. When starting the fire monitor, the control device selects a suitable preset fire-fighting scheme according to the actual situation of the current fire (such as the location of the ignition point, the size of the fire, etc.), and then sends a control signal to the angle adjustment device and flow control device of the fire monitor. The angle adjustment device adjusts the elevation angle and horizontal angle of the muzzle of the fire monitor according to the signal so that it is accurately aimed at the ignition point; the flow control device controls the water supply or liquid supply system of the fire monitor and adjusts the water output to meet the fire extinguishing needs. For example, for a small fire in the early stage, a smaller water output and a more precise spray angle can be used for fixed-point fire extinguishing; for a larger fire, a larger water output is selected and combined with a suitable spray angle to form a large area of fire extinguishing coverage.
[0061] In this step, the effectiveness and pertinence of firefighting can be improved by precisely controlling the spray angle and water output of the fire monitor. The appropriate spray angle ensures that the fire extinguishing agent accurately covers the fire point, avoiding waste of fire extinguishing agent and unnecessary impact on the surrounding non-fire areas; the reasonable water output can ensure effective fire extinguishing without causing water damage or excessive pressure on the fire protection system due to excessive water output. This precise control method helps to improve firefighting efficiency, extinguish fires faster, reduce damage to personnel, equipment and buildings, and reduce economic losses and safety risks caused by fires.
[0062] In summary, this embodiment uses environmental image data to capture and process fire points. Regardless of the complexity of the environment, it can efficiently locate the fire point, quickly match and activate the nearest fire monitor based on the fire point location data, significantly shorten the time for the fire monitor to reach the fire point, and achieve a nearly instant fire extinguishing response, which greatly suppresses the spread of the fire in the early stages. It not only improves the fire extinguishing effect, but also avoids the waste of fire extinguishing agents and unnecessary impacts on the surrounding environment.
