Description

Technical Field

[0001] This application relates to the field of fire protection electrical control technology, and in particular to a fire extinguishing equipment control method and fire extinguishing equipment. Background Technology

[0002] With the rapid development of high-risk locations such as urban high-rise buildings, large logistics warehouses, and chemical industrial parks, fire-fighting equipment, as a core component of fire suppression, is increasingly becoming a crucial guarantee for emergency rescue systems in terms of safety and reliability. Containerized fire-fighting equipment, due to its high degree of integration, rapid deployment, and strong environmental adaptability, is widely used in key protected areas such as petrochemical plants, ports, and airport hangars. This type of equipment is typically equipped with a liftable fire monitor, which uses hydraulic or electric drive mechanisms to adjust the pitch angle and height, meeting the needs of long-distance, high-volume, and multi-angle coverage fire suppression operations.

[0003] Currently, the lifting mechanism and pump control system of fire monitors are mostly designed independently. The lifting mechanism is responsible for adjusting the elevation angle and spray height of the fire monitor, and is usually driven by actuators such as hydraulic cylinders and electric actuators. The pump system drives the fire pump through a diesel engine or electric motor to establish a high-pressure water supply system. Operators need to control the lifting action and pump start / stop through separate control panels. In actual operation, it is easy for the high-pressure pump to start before the fire monitor has reached its maximum height, causing the monitor structure to be subjected to off-center stresses under non-design conditions; it is also possible for the pump to continue running while the fire monitor is descending, causing the high-pressure water flow to continuously impact the descent transmission mechanism and sealing components. These uncontrolled conditions not only threaten the personal safety of on-site operators, but also easily lead to multiple failures such as spray trajectory deviation, abnormal vibration of hydraulic pipelines, accelerated aging of seals, monitor jamming, and even pipeline rupture, seriously weakening the overall operational reliability of the equipment. Summary of the Invention

[0004] This application provides a fire extinguishing equipment control method and fire extinguishing equipment to solve the problem of poor reliability of fire extinguishing equipment in the prior art.

[0005] The technical solutions provided in this application are as follows: On one hand, embodiments of this application provide a method for controlling fire extinguishing equipment, including: In response to motion control commands, obtain the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline connected to the fire monitor; Based on the motion control command, an interlocking action sequence between the fire monitor and the pump unit is generated, and the execution conditions of the interlocking action sequence are determined; wherein, the pump unit is connected to the fire extinguishing pipeline; The fire monitor and pump unit are controlled to execute according to the interlocking action sequence. During the execution of the interlocking action sequence, the current lifting position and current pipeline pressure are compared with the action execution conditions. Based on the comparison results, the actions of the fire monitor and pump unit are switched.

[0006] Optionally, based on the motion control command, an interlocking action sequence between the fire monitor and the pump unit is generated, and the execution conditions of the interlocking action sequence are determined, including: When the motion control command is for the fire monitor to move to the target working position, an interlocking action sequence is generated, including the process of the fire monitor moving to the target working position and the process of the pump unit operating and pressurizing, and the first execution condition of the pump unit operating and pressurizing process is determined; wherein, the pump unit operating and pressurizing process is started after the first execution condition is met; When the motion control command corresponds to the fire monitor moving to the initial position, an interlocking action sequence is generated, including the pump depressurization process and the fire monitor moving to the initial position process, and the second execution condition for the fire monitor moving to the initial position process is determined; wherein, the fire monitor moving to the initial position process is started after the second execution condition is met.

The pre-start speed is determined based on the pre-charge duration, current pipeline pressure, and pre-charge target pressure; The pump unit is controlled to run at the pre-start speed so that it can inject water into the fire extinguishing pipeline and pressurize it to the pre-pressurization target pressure within the pre-pressurization period.

[0010] Optionally, before controlling the pump unit to stop and controlling the pressure relief valve connected to the fire extinguishing pipeline to open in order to execute the pipeline depressurization process, the following steps are also included: Obtain the current media type, fire extinguishing pipeline parameters, and current ambient temperature; Input the current pipeline pressure, current medium type, fire extinguishing pipeline parameters and current ambient temperature into the pressure relief prediction model to obtain the current pressure relief control parameters and predicted safe pressure threshold output by the pressure relief prediction model; Use the current pressure relief control parameters as the current opening degree of the pressure relief valve in the pipeline pressure relief process.

[0011] Update the safety pressure condition in the second execution condition based on the predicted safety pressure threshold.

[0012] Optionally, before obtaining the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline connected to the fire monitor, the following steps are also included: Acquire primary location detection data and redundant location detection data; When the deviation between the primary position detection data and the redundant position detection data exceeds the preset tolerance threshold, the valid data is determined from the primary position detection data and the redundant position detection data as the current lifting position based on the current pipeline pressure data. If no valid data is found in the primary position detection data and the redundant position detection data, the operation of the pump unit and the fire monitor will be locked, and a fault alarm signal will be output.

[0013] On the other hand, this application provides a fire extinguishing device, including: a fire monitor, a fire extinguishing pipeline, a pump set, a pressure relief valve, a first detection module, a second detection module, and a control module; The inlet of the fire extinguishing pipeline is connected to the outlet of the pump unit, and the outlet of the fire extinguishing pipeline is connected to the fire monitor; the pump unit is used to pressurize and fill the fire extinguishing pipeline with water.

[0016] The beneficial effects of the embodiments of this application are as follows: In this embodiment, an interlocking action sequence between the fire monitor and the pump unit is generated by responding to action control commands, and the corresponding action execution conditions are determined. During the execution of this interlocking action sequence, the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline are obtained in real time and compared with the action execution conditions. The action switching between the fire monitor and the pump unit is controlled by the comparison results, thereby realizing the timing interlock and state interlock between the lifting action of the fire monitor and the start and stop action of the pump unit.

[0022] This application provides a fire extinguishing equipment control method, applied to a control module in a fire extinguishing equipment, see below. Figure 1 As shown in the figure, the general flow of the fire extinguishing equipment control method provided in this application embodiment is as follows: Step 101: In response to the motion control command, obtain the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline connected to the fire monitor.

[0023] In practical applications, motion control commands are control signals sent from the operation command module to the control module. These commands include at least two types: the fire monitor moving towards the target working position and the fire monitor moving towards its initial position. The motion control commands include target position information corresponding to the target position the fire monitor needs to reach, i.e., the target working position or initial position the fire monitor needs to reach. The control module responds to the motion control commands by simultaneously acquiring the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline. The current lifting position is the real-time spatial pose data of the fire monitor during its lifting stroke. The current pipeline pressure is the real-time pressure data of the extinguishing medium inside the fire extinguishing pipeline.

[0024] Step 102: Based on the action control command, generate the interlocking action sequence between the fire monitor and the pump unit, and determine the action execution conditions of the interlocking action sequence; wherein, the pump unit is connected to the fire extinguishing pipeline.

[0025] In practical applications, after acquiring the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline, the control module generates an interlocking action sequence between the fire monitor and the pump unit based on the target position information indicated by the action control command. The interlocking action sequence is the result of the control module's safe timing arrangement of the fire monitor's lifting and lowering actions and the pump unit's pressurization or depressurization actions. It includes at least a combination of the fire monitor moving to the target working position and the pump unit's pressurization process, or a combination of the pump unit's depressurization process and the fire monitor moving to its initial position. Simultaneously with generating the interlocking action sequence, the control module determines the action execution conditions for the sequence. These execution conditions are set by the control module for each process node in the interlocking action sequence and are related to the fire monitor's current lifting position and the current pipeline pressure of the fire extinguishing pipeline. They are used to determine the action switching between the fire monitor and the pump unit during the execution of the interlocking action sequence.

[0026] Step 103: Control the fire monitor and pump unit to execute according to the interlocking action sequence. During the execution of the interlocking action sequence, compare the current lifting position and the current pipeline pressure with the action execution conditions. Control the switching of the actions of the fire monitor and pump unit according to the comparison results.

[0027] In practical applications, after generating the interlocking action sequence and determining the action execution conditions, the control module outputs control signals to the fire monitor's lifting mechanism, pump unit, and pressure relief valve, driving the interlocking action sequence into the actual execution phase. Following the sequence of processes in the interlocking action sequence, the control module first activates the execution component corresponding to the current process node and performs real-time monitoring during the execution of that process.

[0028] During the execution of the interlocking action sequence, the control module continuously compares the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline with the action execution conditions. The control module compares the current lifting position value with the corresponding position threshold in the action execution conditions, and simultaneously compares the current pipeline pressure value with the corresponding pressure threshold in the action execution conditions, to obtain a comparison result indicating whether the current physical state meets the requirements for starting the next process node. Based on the comparison result, the control module controls the switching of the fire monitor and pump unit's actions. When the comparison result indicates that both the current lifting position and the current pipeline pressure meet the action execution conditions, the control module triggers the action switching, terminating the execution of the current process node and starting the next process node in the interlocking action sequence. When the comparison result indicates that the current lifting position or the current pipeline pressure does not meet the action execution conditions, the control module maintains the execution state of the current process node or executes shutdown protection, preventing the interlocking action sequence from entering the next process node. This execution and comparison mechanism ensures that the triggering timing of the action switching is entirely determined by the real-time spatial positioning status of the fire monitor and the real-time pressure safety status of the fire extinguishing pipeline. The control module does not rely on fixed delays or open-loop trigger signals to drive action switching. Instead, it takes the mechanical position of the fire monitor and the pressure safety status of the fire extinguishing pipeline as necessary prerequisites for action switching, forming a dual closed-loop constraint of position and pressure.

[0029] In this way, by responding to action control commands, an interlocking action sequence between the fire monitor and the pump unit is generated, and the corresponding action execution conditions are determined. During the execution of this interlocking action sequence, the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline are obtained in real time and compared with the action execution conditions. The comparison results are used to control the action switching of the fire monitor and the pump unit, thereby realizing the timing interlock and state interlock between the lifting action of the fire monitor and the start and stop action of the pump unit. This effectively avoids the risk of misoperation, such as starting the pump unit before the fire monitor reaches the target position or driving the fire monitor to operate before the pump unit has established effective pressure. This significantly improves the safety and reliability of the fire extinguishing equipment operation. Furthermore, by using the execution of the interlocking action sequence and the action switching control based on real-time state comparison, the accuracy and coordination efficiency of the fire extinguishing response are improved.

[0030] In one possible implementation, based on the motion control command, an interlocking action sequence between the fire monitor and the pump unit is generated, and the execution conditions of the interlocking action sequence are determined, including: When the motion control command is for the fire monitor to move to the target working position, an interlocking action sequence is generated, including the process of the fire monitor moving to the target working position and the process of the pump unit pressurizing, and the first execution condition of the pump unit pressurizing process is determined; wherein, the pump unit pressurizing process is started after the first execution condition is met.

[0031] In practical applications, when the motion control command is for the fire monitor to move towards the target working position, the control module invokes and generates an interlocked action sequence consisting of the fire monitor moving to the target working position and the pump pressurization process. In this interlocked action sequence, the fire monitor moving to the target working position is set as the preceding process, and the pump pressurization process is set as the following process, forming a sequence of actions where the monitor first rises and falls to its position, and then pressurization occurs. The fire monitor moving to the target working position process involves the control module controlling the fire monitor's lifting mechanism to mechanically displace the fire monitor towards the target working position. The pump pressurization process occurs after the fire monitor has reached the target working position, whereby the control module controls the pump to adjust the pressure in the fire extinguishing pipeline to the target working pressure, enabling the fire monitor to perform the formal fire extinguishing medium spraying operation. During the process of moving the fire monitor to the target working position, the control module also controls the execution of the pre-pressurization process. The pre-pressurization process is a preparatory stage where the control module controls the pump unit to operate at a pre-start speed to pressurize the fire extinguishing pipeline to the pre-pressurization target pressure. The pump unit pressurization process is the operational stage where the control module controls the fire monitor to perform the formal spraying of the extinguishing medium. The control module simultaneously determines the first execution conditions for the pump unit pressurization process. The first condition is whether the current lifting position of the fire monitor meets the target working position arrival condition. The target working position arrival condition is that the positional deviation between the current lifting position of the fire monitor and the target working position is within the positional deviation range. When the current lifting position of the fire monitor reaches the target working position and the positional deviation is within the positional deviation range, it is determined that the fire monitor has completed the mechanical arrival action to the target working position. The second condition is whether the current pipeline pressure of the fire extinguishing pipeline meets the pre-pressurization target pressure condition. The pre-pressurization target pressure condition is that the current pipeline pressure of the fire extinguishing pipeline reaches the pre-pressurization target pressure. The pre-pressurization target pressure is an adaptive pipeline pressure determined by the control module based on the target working pressure, and it is greater than the target working pressure. The purpose of this pre-pressurization target pressure is to establish a base pressure higher than the target working pressure in the fire extinguishing pipeline before the fire monitor reaches the target working position, ensuring a smooth transition of the pump unit to the target working pressure during subsequent operations. When the current pipeline pressure in the fire extinguishing pipeline reaches the pre-pressurization target pressure, it is determined that the fire extinguishing pipeline has reached the base pressure state for the pump unit to enter formal pressurization operation. The control module sets the pump unit pressurization process to start only after the first execution condition is met, ensuring that the pump unit will not enter formal pressurization and spraying state until the fire monitor has completed mechanical positioning and the pipeline has established base pressure.

[0032] When the motion control command corresponds to the fire monitor moving to the initial position, an interlocking action sequence is generated, including the pump depressurization process and the fire monitor moving to the initial position process, and the second execution condition for the fire monitor moving to the initial position process is determined; wherein, the fire monitor moving to the initial position process is started after the second execution condition is met.

[0033] In practical applications, when the motion control command is for the fire monitor to move to its initial position, the control module invokes and generates an interlocked action sequence consisting of a pump depressurization process and a fire monitor moving to its initial position process. In this interlocked action sequence, the pump depressurization process is set as the preceding process, and the fire monitor moving to its initial position process is set as the following process, forming a sequence of depressurization followed by movement. The pump depressurization process involves the control module stopping the pump and opening the pressure relief valve connected to the fire extinguishing pipeline to safely release residual pressure in the pipeline. The fire monitor moving to its initial position process involves the control module controlling the fire monitor to move to its initial position. Simultaneously, the control module determines the second execution condition for the fire monitor moving to its initial position process. The second execution condition includes at least two verification items. The first is whether the current pipeline pressure of the fire extinguishing pipeline meets the safe pressure condition. The safe pressure condition is that the current pipeline pressure is less than the safe pressure threshold that allows the fire monitor to move safely. When the current pipeline pressure is less than the safe pressure threshold, it is determined that the fire extinguishing pipeline has completed depressurization and possesses the basic pressure state for safe movement. The second condition is whether the current lifting position of the fire monitor meets the initial position activation conditions. The initial position activation conditions refer to the confirmation criteria for determining whether the fire monitor is in the target working position, i.e., whether the current lifting position of the fire monitor is in the target working position, and not in an abnormal intermediate position due to mechanical jamming, thus confirming that the fire monitor has the prerequisite state to move to the initial position. When the current lifting position of the fire monitor is in the target working position, it is determined that the fire monitor has the prerequisite state to move to the initial position; if the fire monitor is in an abnormal intermediate position, it indicates that the lifting mechanism is mechanically jammed or abnormally positioned, and the control module prohibits the initiation of the fire monitor movement to the initial position process. The control module is set to initiate the fire monitor movement to the initial position process only after the second execution condition is met, ensuring that the fire monitor will not move to the initial position when the fire extinguishing pipeline is pressurized or when it is in an abnormal intermediate position.

[0034] In one possible implementation, see [reference] Figure 2 As shown, when the motion control command is for the fire monitor to move towards the target working position, the fire monitor and pump unit are controlled to execute according to the interlocking action sequence. During the execution of the interlocking action sequence, the current lifting position and current pipeline pressure are compared with the action execution conditions. Based on the comparison results, the actions of the fire monitor and pump unit are switched, including: Step 201: Control the fire monitor to move to the target working position.

[0035] In practical applications, after generating the interlocking action sequence and determining the first execution condition, the control module outputs a lifting control signal to the fire monitor's lifting mechanism, initiating the process of moving the fire monitor to the target working position. This drives the fire monitor to mechanically displace from its initial position to the target working position, allowing it to reach the predetermined fire extinguishing location. Simultaneously, the control module controls the opening of the pump set outlet check valve and the fire monitor's inlet valve, creating a continuous fluid path from the pump set outlet check valve to the fire monitor in the fire extinguishing pipeline, establishing a complete water filling path for the subsequent pre-pressurization process. During the execution of the fire monitor moving to the target working position, the control module simultaneously keeps the pump set in a standby state, without performing formal pressurization. At this time, the fire monitor's mechanical lifting action and the pump set's formal pressurization action are time-isolated by the control module; the fire monitor's lifting action is executed first, and the pump set's formal pressurization action is postponed.

[0036] Step 202: During the process of moving the fire monitor to the target working position, compare the current lifting position and the current pipeline pressure with the first execution condition.

[0037] In practical applications, during the process of moving the fire monitor to the target working position, the control module continuously compares the current lifting position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline with the first execution condition in real time. This real-time comparison process specifically includes: comparing the current lifting position with a preset position deviation threshold in the first execution condition to determine if the position deviation between the current lifting position and the target working position is within the specified range; and comparing the current pipeline pressure with the pre-pressurization target pressure threshold in the first execution condition to determine if the current pipeline pressure has reached the pre-pressurization target pressure. This comparison is not a single-trigger judgment but a continuous monitoring process throughout the entire cycle of the fire monitor moving to the target working position. If, during the comparison process, the position deviation exceeds the specified range, or the current pipeline pressure does not reach the pre-pressurization target pressure, the control module maintains the execution state of the fire monitor moving to the target working position and does not trigger subsequent process switching, thereby preventing the fire monitor from prematurely entering the pressurization and spraying stage before completing mechanical positioning or before the pipeline has established basic pressure.

[0038] Step 203: If the current lifting position and the current pipeline pressure both meet the first execution condition within a continuous first preset time period, then control the pump unit to execute the pump unit operation pressurization process.

[0039] In practical applications, within a continuous first preset time period, if the positional deviation between the current lifting position and the target working position of the fire monitor remains within the specified range, and the current pipeline pressure of the fire extinguishing pipeline consistently reaches the pre-pressurization target pressure, the control module confirms that the fire monitor has completed mechanical positioning and the fire extinguishing pipeline has the foundation for pressurization. This triggers a switch from the fire monitor moving to the target working position to the pump unit pressurization process. The first preset time period is a delay confirmation window set by the control module to eliminate misjudgments caused by on-site mechanical vibration, sensor signal jitter, or instantaneous pressure fluctuations, ensuring that the action switch is based on a stable and reliable physical state. The control module keeps the pump unit outlet check valve and the fire monitor inlet valve open, allowing the pressurized medium output from the pump unit to be continuously delivered to the fire monitor through the fire extinguishing pipeline, forming a complete spray path from the pump unit outlet check valve to the fire monitor inlet valve. The control module outputs a control signal to the pump unit, controlling it to adjust the fire extinguishing pipeline pressure from the pre-pressurization target pressure to the target working pressure, enabling the fire monitor to perform formal fire extinguishing medium spraying. By consistently meeting the dual thresholds within a first preset time period, the control module dually binds the start-up timing of the pump unit's formal pressurization and spraying with the mechanical positioning status of the fire monitor and the pressure status of the fire extinguishing pipeline, forming a safe action switching under the closed-loop constraints of position and pressure conditions.

[0040] In one possible implementation, see [reference] Figure 3 As shown, when the motion control command is for the fire monitor to move to its initial position, the fire monitor and pump unit are controlled to execute according to the interlocked action sequence. During the execution of the interlocked action sequence, the current lifting position and current pipeline pressure are compared with the action execution conditions. Based on the comparison results, the actions of the fire monitor and pump unit are switched, including: Step 301: Control the pump unit to stop and control the pressure relief valve connected to the fire extinguishing pipeline to open in order to execute the pipeline depressurization process.

[0041] In practical applications, after generating the interlocking action sequence and determining the second execution condition, the control module outputs a shutdown control signal to the pump unit. The control module then closes the inlet valve of the fire monitor, isolating it from the fire extinguishing pipeline. Next, it opens the pressure relief valve connected to the fire extinguishing pipeline, safely releasing residual pressure and preventing the extinguishing medium from spraying out of the fire monitor during depressurization, thus initiating the pipeline depressurization process. This process is a pre-process in the interlocking action sequence, its technical purpose being to stop the pump unit from pressurizing the fire extinguishing pipeline and safely release residual pressure through the pressure relief valve, reducing the pressure in the fire extinguishing pipeline to a level that allows the fire monitor to move safely. During this process, the control module maintains the fire monitor's current position and does not perform any movement to the initial position, ensuring the fire monitor remains stationary while the fire extinguishing pipeline is pressurized, preventing mechanical shock or seal damage caused by pressurized movement. By executing this pre-process, the control module establishes the necessary pressure safety foundation for the subsequent movement of the fire monitor to the initial position.

[0042] Step 302: During the execution of the pipeline depressurization process, compare the current pipeline pressure and the current rise / fall position with the second execution condition.

[0043] In practical applications, during the pipeline depressurization process, the control module continuously compares the current pipeline pressure and the current lifting / lowering position of the fire monitor with the second execution conditions in real time. This comparison process specifically includes: comparing the current pipeline pressure with the safe pressure threshold in the second execution conditions to determine if the current pipeline pressure has dropped below the safe pressure threshold; and comparing the current lifting / lowering position with the initial position action condition in the second execution conditions to determine if the fire monitor's current lifting / lowering position is at the target working position rather than an intermediate abnormal position. This comparison is not a single-trigger judgment but a continuous monitoring process throughout the entire pipeline depressurization process. If, during the comparison process, the current pipeline pressure has not dropped below the safe pressure threshold, or the current lifting / lowering position is not at the target working position, the control module maintains the execution state of the pipeline depressurization process and prohibits the fire monitor from initiating movement towards the initial position, thereby preventing the fire monitor from performing a lowering action when the fire pipeline is pressurized or in a mechanically jammed abnormal position.

[0044] Step 303: If the current pipeline pressure and the current lifting position both meet the second execution condition within a continuous second preset time period, control the fire monitor to execute the process of moving the fire monitor to the initial position.

[0045] In practical applications, within a continuous second preset time period, if the current pipeline pressure of the fire extinguishing pipeline continuously drops below the safe pressure threshold, and the current lifting position of the fire monitor remains at the target working position, the control module confirms that the fire extinguishing pipeline has completed safe depressurization and the fire monitor is in a condition allowing movement. This triggers a switch from the pipeline depressurization process to the fire monitor moving to its initial position. The second preset time period is a delay confirmation window set by the control module to eliminate misjudgments caused by pressure fluctuations or sensor signal jitter, ensuring that the action switch is based on a stable and reliable physical state. The control module outputs a control signal to the fire monitor, controlling it to move to its initial position and complete the reset action. By stably satisfying the dual thresholds within a continuous second preset time period, the control module dual-binds the timing of the fire monitor's descent and reset with the pressure safety status of the fire extinguishing pipeline and the position confirmation status of the fire monitor, forming a safe action switch under closed-loop constraints of pressure and position conditions.

[0046] In one possible implementation, the process of moving the fire monitor to the target working position further includes: First, obtain the target working pressure, current ambient temperature, fire extinguishing pipeline parameters, and fire monitor load parameters.

[0047] In practical applications, during the process of moving the fire monitor to the target working position, the control module simultaneously collects the operating parameters required by the pre-charge prediction model. The target working pressure refers to the pressure target value that the fire extinguishing pipeline needs to establish when the pump unit enters the formal fire extinguishing operation phase. The target working pressure is carried by the action control command, and the control module directly parses and obtains this target working pressure from the command when responding to the action control command. The current ambient temperature refers to the ambient air temperature at the location of the fire extinguishing equipment, which affects the fluidity of the extinguishing medium and the thermal state of the pipeline system. It is collected in real time by the temperature detection unit installed on the equipment and fed back to the control module. Fire extinguishing pipeline parameters refer to the inherent structural properties of the fire extinguishing pipeline, including at least pipeline length, diameter, and resistance characteristics. These parameters are pre-stored in the control module's storage unit or pre-input by the operator. Fire monitor load parameters refer to the mechanical load characteristics of the fire monitor, including the load state related to the monitor's weight and spray angle. These parameters are pre-stored in the control module's storage unit. The control module establishes a complete operating condition input for the pre-charge prediction model by synchronously acquiring the above multi-dimensional parameters, so that the prediction results of the pre-charge duration and the pre-charge target pressure are adapted to the current equipment operating conditions and the field environment.

[0048] Then, the current pipeline pressure, target working pressure, current ambient temperature, pipeline parameters, and fire monitor load parameters are input into the pre-charge prediction model to obtain the pre-charge duration and pre-charge target pressure output by the pre-charge prediction model.

[0049] In practical applications, the pre-charge prediction model determines the pre-charge duration and target pre-charge pressure based on the pressure difference between the current pipeline pressure and the target working pressure, combined with ambient temperature, pipeline parameters, and fire monitor load parameters, using a built-in prediction algorithm. The pre-charge duration is the time window required for the pump unit to complete the pre-charge process while the fire monitor moves from its current position to the target working position. The target pre-charge pressure is the pressure level that the fire extinguishing pipeline needs to reach at the end of the pre-charge phase. This pressure level is determined by the target working pressure and is greater than the target working pressure. The technical purpose is to establish a base pressure higher than the formal operating pressure in the fire extinguishing pipeline before the fire monitor reaches the target working position, ensuring a smooth transition during the subsequent formal pressurization phase. The control module, through the pre-charge prediction model, transforms the pre-charge process from fixed-sequence control to adaptive control based on real-time operating conditions.

[0050] Specifically, the pre-charge prediction model is a deep learning-based multivariate regression prediction model, constructed based on the correlation mapping between historical operation data and pre-charge control parameters. This model uses deep learning algorithms to extract patterns and learn features from environmental parameters, pipeline parameters, fire monitor load parameters, and pressure change characteristics in historical operation data, establishing a nonlinear mapping relationship between multiple input variables and pre-charge duration and target pre-charge pressure. The historical operation data includes the actual duration and achieved pre-charge pressure under different ambient temperatures, pipeline lengths, pipeline resistances, fire monitor loads, and initial pressures. The pre-charge prediction model uses current pipeline pressure, target working pressure, current ambient temperature, fire extinguishing pipeline parameters, and fire monitor load parameters as input features, and pre-charge duration and target pre-charge pressure as output predictions. Through a built-in prediction network structure, it performs nonlinear fitting and inference calculations on the input features, outputting pre-charge control parameters adapted to the current operating conditions. This model is deployed in the control module and achieves adaptive control of the pre-charge process through online invocation during equipment operation, rather than model training during the real-time control phase.

[0051] Next, the pre-start speed is determined based on the pre-charge duration, current pipeline pressure, and pre-charge target pressure.

[0052] In practical applications, the pre-start speed is the operating speed of the pump set during the pre-charging phase. Based on the pressure difference between the current pipeline pressure and the target pre-charging pressure, as well as the pressurization time window defined by the pre-charging duration, the required pressurization rate of the pump set is calculated and then mapped to the corresponding pre-start speed. This pre-start speed is lower than the operating speed of the pump set during the formal operation phase, allowing the pump set to operate in a soft-start mode, reducing the hydraulic impact on the pipeline system at startup, and ensuring that the pre-charging process is completed before the fire monitor reaches the target working position.

[0053] Finally, the pump unit is controlled to run at the pre-start speed so that the pump unit can inject water into the fire extinguishing pipeline and pressurize it to the pre-pressurization target pressure within the pre-pressurization time.

[0054] In practical applications, the control module outputs a speed control signal to the pump unit, controlling it to operate at a predetermined pre-start speed. The pump unit pressurizes the fire extinguishing pipeline at this pre-start speed, continuing operation until the pre-pressurization period ends or the current pipeline pressure reaches the pre-pressurization target pressure. This process allows the fire extinguishing pipeline to gradually establish and stabilize at the pre-pressurization target pressure level during the fire monitor's movement to the target working position, rather than rapidly starting from zero pressure after the fire monitor arrives. By interleaving the pre-pressurization process, the control module parallelizes the pump unit's pressurization action with the fire monitor's raising and lowering action in time, ensuring that the fire extinguishing pipeline has a base pressure higher than the target working pressure when the fire monitor reaches the target working position. This shortens the start-up time of the formal pressurization process and reduces the impact of sudden pressure changes on the pipeline and fire monitor.

[0055] In one possible implementation, before controlling the pump unit to stop and controlling the pressure relief valve connected to the fire extinguishing pipeline to open to execute the pipeline depressurization process, the method further includes: First, obtain the current media type, fire extinguishing pipeline parameters, and current ambient temperature.

[0056] In practical applications, before executing the pipeline depressurization process, the control module synchronously collects the operating parameters required for the depressurization prediction model. The current medium type refers to the type of extinguishing medium currently filling the fire extinguishing pipeline, including water or foam; this parameter is pre-input into the control module by the operator. The fire extinguishing pipeline parameters refer to the inherent structural properties of the fire extinguishing pipeline, including at least pipeline length, diameter, and resistance characteristics; these parameters are pre-stored in the control module's storage unit or pre-input by the operator. The current ambient temperature is collected and fed back in real-time by a temperature detection unit installed on the equipment. This parameter affects the viscosity of the extinguishing medium and the thermal expansion and contraction of the pipeline system; reduced medium fluidity at low temperatures will slow down the depressurization rate. By synchronously acquiring these multi-dimensional operating parameters, the control module establishes a real-time input basis for the depressurization prediction model, enabling subsequent depressurization control to adapt to the current medium characteristics and on-site environmental conditions.

[0057] Then, the current pipeline pressure, current medium type, fire extinguishing pipeline parameters, and current ambient temperature are input into the pressure relief prediction model to obtain the current pressure relief control parameters and predicted safe pressure threshold output by the pressure relief prediction model.

[0058] In practical applications, the pressure relief prediction model is a condition prediction model built based on historical pressure relief data. This model establishes a mapping relationship between input conditions and pressure relief control parameters using pressure relief process data under different media types, pipeline lengths, temperatures, and initial pressures during historical operations. Based on the current pipeline pressure, current media type, fire extinguishing pipeline parameters, and current ambient temperature, the pressure relief prediction model infers and determines the pressure relief characteristics under the current conditions, outputting the current pressure relief control parameters and the safe pressure threshold. The current pressure relief control parameters are the pressure relief valve control quantities determined by the pressure relief prediction model based on the current conditions, used to adjust the pressure relief rate. The pressure relief valve control quantities are expressed in units of pressure relief valve opening percentage or target flow coefficient, representing the required opening range of the pressure relief valve under the current conditions. The safe pressure threshold is a pressure judgment benchmark dynamically calculated by the pressure relief prediction model based on the current conditions, used to determine whether the fire extinguishing pipeline has been depressurized to a state that allows the fire monitor to move safely. The control module, through online inference from the pressure relief prediction model, transforms the fixed pressure relief control into adaptive pressure relief control based on real-time conditions.

[0059] Specifically, the pressure relief prediction model is a deep learning-based multivariate regression prediction model, constructed based on the correlation mapping between historical pressure relief data and pressure relief control parameters. This model uses deep learning algorithms to extract patterns and learn features from the media type, pipeline length, ambient temperature, and pressure decay characteristics in the historical pressure relief data, establishing a nonlinear mapping relationship between multiple input variables and the current pressure relief control parameters and safe pressure thresholds. The historical pressure relief data includes the actual pressure relief time, actual pressure decay curves, and corresponding safe pressure judgment values ​​required to complete the pipeline pressure relief process under different media types, pipeline lengths, ambient temperatures, and initial pressure conditions. The pressure relief prediction model uses the current pipeline pressure, current media type, fire extinguishing pipeline length, and current ambient temperature as input features, and the current pressure relief control parameters and safe pressure thresholds as output predictions. Through a built-in prediction network structure, it performs nonlinear fitting and inference calculations on the input features, outputting pressure relief control parameters adapted to the current operating conditions. This model is deployed in the control module, achieving adaptive control of the pipeline pressure relief process through online invocation during equipment operation, rather than model training during the real-time control phase.

[0060] Next, the current pressure relief control parameters will be used as the current opening degree of the pressure relief valve in the pipeline pressure relief process.

[0061] In practical applications, the current pressure relief control parameters directly determine the opening range of the pressure relief valve during the pipeline depressurization process, thereby controlling the rate of residual pressure release within the fire extinguishing pipeline. During the pipeline depressurization process, the control module converts the current pressure relief control parameters into a pressure relief valve drive signal. This signal drives the actuator of the pressure relief valve to adjust the valve core displacement, ensuring the actual opening of the pressure relief valve reaches the opening range indicated by the current pressure relief control parameters. This conversion process is based on a linear mapping relationship between the current pressure relief control parameters and the full-stroke opening of the pressure relief valve. The control module calculates the drive amount of the pressure relief valve actuator based on this mapping relationship and outputs the corresponding control signal to the pressure relief valve's drive unit, driving the pressure relief valve to open to the target opening. Under different operating conditions, the current pressure relief control parameters result in different opening commands for the pressure relief valve: when the medium viscosity is high or the pipeline is long, the current pressure relief control parameters correspond to a larger pressure relief valve opening to accelerate the depressurization speed; when the medium has good fluidity or a high temperature, the current pressure relief control parameters correspond to a smaller pressure relief valve opening to prevent sudden pressure changes from impacting the pipeline system. The control module achieves safe soft depressurization of the fire extinguishing pipeline by adjusting the opening degree based on the current pressure relief control parameters, avoiding the problem of excessively fast or slow depressurization under a fixed opening degree.

[0062] Finally, based on the safety pressure threshold, the safety pressure condition in the second execution condition is updated.

[0063] In practical applications, after obtaining the safe pressure threshold output by the pressure relief prediction model, the control module updates the fixed safe pressure threshold in the second execution condition to the predicted safe pressure threshold, dynamically adapting the pressure zeroing condition to the current operating conditions. This predicted safe pressure threshold comprehensively considers the vaporization pressure of the current medium, the temperature compensation coefficient, and the sensor accuracy; it is not fixed at zero, but rather represents the minimum pressure level that allows the fire monitor to move safely under the current operating conditions. During the pipeline pressure relief process, the control module compares the current pipeline pressure with the predicted safe pressure threshold in real time. Only when the current pipeline pressure drops below this predicted safe pressure threshold is the fire monitor allowed to move to its initial position and the process initiated. By dynamically updating the safe pressure condition, the control module ensures that the pressure safety judgment for the fire monitor's descent and reset matches the real-time operating conditions, avoiding misjudgments caused by fixed thresholds under conditions such as low temperature and high viscosity media.

[0064] In one possible implementation, before obtaining the current elevation position of the fire monitor and the current pipeline pressure of the fire extinguishing pipeline connected to the fire monitor, the method further includes: First, acquire the primary location detection data and the redundant location detection data.

[0065] In practical applications, before acquiring the current lifting position of the fire monitor, the control module simultaneously establishes a dual-channel position detection mechanism. The control module acquires primary position detection data, collected by the primary position detection unit located at the fire monitor's lifting actuator, directly reflecting the actual spatial coordinates of the actuator. Simultaneously, the control module acquires redundant position detection data, collected by a redundant position detection unit located at the fire monitor's lifting drive end, reflecting the drive displacement. This dual-channel synchronous acquisition establishes a cross-validation data source between the actual position of the actuator and the theoretical position of the drive end, providing a dual-input basis for subsequent determination of the position data's validity.

[0066] Then, when the deviation between the main position detection data and the redundant position detection data exceeds the preset tolerance threshold, the valid data is determined from the main position detection data and the redundant position detection data based on the current pipeline pressure data as the current lifting position; when there is no valid data in the main position detection data and the redundant position detection data, the operation of the pump unit and the fire monitor is locked, and a fault alarm signal is output.

[0067] In practical applications, after acquiring the primary position detection data and the redundant position detection data, the control module calculates the deviation between the two and compares this deviation with a preset tolerance threshold. This preset tolerance threshold is the allowable deviation range set by the control module to determine whether the dual-channel position data is in a normal consistency state.

[0068] If the deviation exceeds a preset tolerance threshold, the control module determines the validity of both the primary position detection data and the redundant position detection data based on the current pipeline pressure data. The control module determines the current theoretical position of the fire monitor based on the correspondence between pipeline pressure and the fire monitor's lifting / lowering position using the current pipeline pressure data. Using this theoretical position as the center, it determines an allowable position range based on a preset theoretical deviation value. The control module compares the primary position detection data and the redundant position detection data with this allowable position range. If the primary position detection data is within the allowable position range while the redundant position detection data is outside, the control module determines the primary position detection data as valid. If the redundant position detection data is within the allowable position range while the primary position detection data is outside, the control module determines the redundant position detection data as valid. The control module uses the determined valid data as the current lifting / lowering position. If both the primary position detection data and the redundant position detection data are outside the allowable position range, the control module determines that both position detection methods have failed. In this case, the control module locks the operation of the pump unit and the fire monitor and outputs a fault alarm signal.

[0069] Based on the above embodiments, this application provides a fire extinguishing device, see reference. Figure 4As shown, the fire extinguishing equipment 1 provided in this application embodiment includes at least: a fire monitor 2, a fire extinguishing pipeline 3, a pump set 4, a pressure relief valve 5, a first detection module 6, a second detection module 7, and a control module 8; The inlet of the fire extinguishing pipeline 3 is connected to the outlet of the pump set 4, and the outlet of the fire extinguishing pipeline 3 is connected to the fire monitor 2; the pump set 4 is used to pressurize the fire extinguishing pipeline 3 with water. The pressure relief valve 5 is installed on the fire extinguishing pipeline 3 and is used to release the pressure in the fire extinguishing pipeline 3. The first detection module 6 is installed on the fire monitor 2; the first detection module 6 is used to detect the current lifting position of the fire monitor 2; The second detection module 7 is installed on the fire extinguishing pipeline 3; the second detection module 7 is used to detect the current pipeline pressure of the fire extinguishing pipeline 3. The control module 8 is electrically connected to the first detection module 6, the second detection module 7, the pump group 4, the pressure relief valve 5 and the fire monitor 2 respectively. The control module 8 is used to execute the control method of the fire extinguishing equipment 1 described above.

[0070] In practical applications, the inlet of fire extinguishing pipeline 3 is connected to the outlet of pump unit 4, and the outlet of fire extinguishing pipeline 3 is connected to fire monitor 2. Pump unit 4 is used to fill and pressurize fire extinguishing pipeline 3. Specifically, pump unit 4 includes a motor, pump body, frequency converter, and overload protection unit. The motor receives speed commands from control module 8 through the frequency converter to achieve continuous adjustment of output flow and pressure. The pump body is connected to the inlet of fire extinguishing pipeline 3 to fill and pressurize the fire extinguishing pipeline 3. The overload protection unit monitors the operating current of pump unit 4 and sends a protection signal back to control module 8 when an overload occurs. As the power source of the system, pump unit 4 integrates a frequency converter and overload protection unit, enabling it to receive speed or torque commands from control module 8 and achieve continuous linear adjustment of output flow and pressure, rather than being limited to traditional power frequency start-stop control. This variable frequency drive capability is the physical prerequisite for the realization of pre-start speed control and soft pressure relief strategies. Fire extinguishing pipeline 3 is typically made of pressure-resistant seamless steel pipe or high-pressure composite hose. Its pipe diameter, length, and elbow layout, among other geometric parameters, directly determine the hydraulic characteristics of the system. These parameters are calibrated and stored in control module 8 during the system commissioning phase, serving as static input variables for the pre-charge prediction model and the depressurization prediction model. Fire monitor 2 includes a lifting mechanism, a pitch and slewing mechanism, and a jet channel. The lifting mechanism, consisting of a lifting motor, a transmission screw or hydraulic cylinder, and a guide rail, drives the fire monitor 2 to switch positions vertically. The pitch and slewing mechanism, consisting of a pitch motor and a slewing motor, adjusts the spray angle. Nozzles are installed at the end of the jet channel, and the inlet of the jet channel is connected to the outlet of fire extinguishing pipeline 3. As the terminal actuator, the internal channel design and nozzle structure of fire monitor 2 must match the rated operating conditions of pump unit 4 to ensure that the designed range and flow rate are achieved under the target working pressure.

[0071] Pressure relief valve 5 is installed on fire extinguishing pipeline 3 and is used to release pressure in fire extinguishing pipeline 3. Specifically, pressure relief valve 5 includes a valve body, a valve core, and an actuation drive unit; the valve body is internally connected to the fire extinguishing pipeline 3, and the discharge port is connected to a return channel or drainage network; the actuation drive unit can be an electric proportional adjustment mechanism or an electromagnetic switch mechanism, which receives the opening control signal from control module 8 and adjusts the valve core displacement to control the release flow. The installation position of pressure relief valve 5 is preferably located in the pipeline section after the outlet check valve of pump group 4 and before the inlet valve of fire monitor 2, to ensure that the residual pressure in the entire working pipeline section can be effectively released after pump group 4 stops. In a preferred embodiment, pressure relief valve 5 adopts an electric proportional adjustment valve or a servo valve, and its opening degree can be precisely adjusted in real time by control module 8 according to the current pressure relief control parameters output by the pressure relief prediction model, thereby realizing controlled soft pressure relief function and avoiding pressure drop and water hammer impact caused by instantaneous full opening of the valve. In another embodiment, the pressure relief valve 5 can also be composed of an electromagnetic switching valve connected in series with a fixed orifice plate, simulating a continuous regulation effect through pulse width modulation. Furthermore, the discharge port of the pressure relief valve 5 should be connected to a safe return channel or drainage network to prevent secondary hazards caused by disorderly jetting of high-pressure media. By upgrading the pressure relief valve 5 from a simple safety accessory to an active control element, this embodiment makes the energy release process under descent conditions observable and controllable, fundamentally improving the safety of the reset operation.

[0072] The first detection module 6 is installed on the fire monitor 2; the first detection module 6 is used to detect the current lifting position of the fire monitor 2. The second detection module 7 is installed on the fire extinguishing pipeline 3; the second detection module 7 is used to detect the current pipeline pressure of the fire extinguishing pipeline 3. Specifically, the second detection module 7 includes a pressure detection device and a signal conditioning unit; the pressure detection device is a high-precision pressure transmitter or pressure sensor, used to collect the real-time pressure status inside the fire extinguishing pipeline 3; the signal conditioning unit includes a filtering circuit and an analog-to-digital conversion circuit, used to convert the raw signal from the pressure detection device into a standard digital quantity. The pressure detection device of the second detection module 7 is composed of a high-precision pressure transmitter or pressure sensor. In terms of installation position, the second detection module 7 is arranged near the inlet of the fire monitor 2 or the end of the pipeline to directly sense the effective pressure actually acting on the monitor body and reduce measurement deviations caused by friction loss along the way. Meanwhile, in order to cope with the strong mechanical vibration and electromagnetic interference at the fire operation site, the signal transmission line of the second detection module 7 should use a double-shielded cable, and integrate low-pass filtering and surge protection devices in the signal conditioning circuit to ensure that the collected current pipeline pressure data truly reflects the hydraulic state rather than environmental noise.

[0073] The control module 8 is electrically connected to the first detection module 6, the second detection module 7, the pump group 4, the pressure relief valve 5, and the fire monitor 2, respectively. The control module 8 is used to execute the control method of the fire extinguishing equipment 1 described above. Specifically, the control module 8 is the intelligent hub of the entire equipment, and its hardware architecture is configured to run complex interlocking logic and AI prediction algorithms. In a typical embodiment, the control module 8 includes an intelligent controller equipped with a deep learning acceleration unit, a real-time I / O interface board, and a safety relay circuit. The intelligent controller is responsible for running the pre-charge prediction model, the depressurization prediction model, and the data fusion algorithm, processing the high-frequency data streams from each detection module, and generating the optimal control strategy; the real-time I / O interface board is responsible for converting digital control commands into analog or PWM signals to drive the frequency converter of the pump group 4 and the actuator of the pressure relief valve 5, and at the same time converting the original sensor signals into standard digital quantities for algorithm calls; the safety relay circuit serves as a hardware-level safety fallback independent of the software logic. When an emergency stop signal, over-limit alarm, or communication interruption is detected, it directly cuts off the power supply and triggers mechanical braking to ensure that the equipment can still enter a safe state when the control system fails. The electrical connection between control module 8 and other modules can be a wired industrial bus, a wireless communication link, or a point-to-point hardwired connection, depending on the field wiring conditions and real-time requirements. It should be understood that although this embodiment uses a centralized controller as an example, in other embodiments, distributed edge computing nodes or embedded microprocessor arrays can also be used to achieve the same function, as long as they have the computing resources and interface capabilities required to execute the aforementioned control method.

[0074] In one possible implementation, see [reference] Figure 5 As shown, the first detection module 6 includes a main position detection unit 9 and a redundant position detection unit 10; The main position detection unit 9 is installed at the lifting and lowering actuator of the fire monitor 2. The main position detection unit 9 is used to acquire main position detection data. The redundant position detection unit 10 is installed at the lifting drive end of the fire monitor 2. The redundant position detection unit 10 is used to acquire redundant position detection data.

[0075] In practical applications, the main position detection unit 9 is installed at the lifting actuator end of the fire monitor 2, and is used to acquire main position detection data. The lifting actuator end refers to the mechanical end component that directly supports the fire monitor 2 body and performs pitch or lifting movements, such as the pitch rotation shaft of the fire monitor body, the top slider of the lifting column, or the output shaft of the rocker arm mechanism. Installing the main position detection unit 9 here allows for direct measurement of the actual spatial attitude of the fire monitor body relative to the base or horizontal reference, eliminating the accumulation of errors introduced by intermediate transmission links. In a preferred embodiment, the main position detection unit 9 can be a high-precision absolute encoder, tilt sensor, or drawstring displacement meter. For example, when using an absolute encoder, its shaft is directly coaxially connected to the pitch shaft via a coupling or hollow bushing, outputting the absolute angle value of the fire monitor body in real time; when using a tilt sensor, its housing is rigidly fixed to the side or top plane of the fire monitor body, and the tilt angle of the fire monitor body is calculated through gravity vector calculation. The main position detection data are all considered as the preferred reference for characterizing the actual operating attitude of the fire monitor 2.

[0076] A redundant position detection unit 10 is installed at the lifting drive end of the fire monitor 2. This unit acquires redundant position detection data. Specifically, the lifting drive end refers to the mechanical source component that provides power input for the lifting movement of the fire monitor 2, such as the output shaft of a drive motor, the input shaft of a reducer, the drum shaft of a winch, or the rotor shaft of a hydraulic motor. Installing the redundant position detection unit 10 here allows for independent sensing of the power source's output state; the data reflects the ideal position reached by the fire monitor body, rather than its actual position. In a preferred embodiment, the redundant position detection unit 10 can employ an incremental photoelectric encoder, a rotary transformer, or a Hall sensor built into the motor. For example, an incremental encoder installed at the tail of the servo motor calculates the number of revolutions the motor has made by accumulating pulse counts, and then, combined with the reducer speed ratio, derives the theoretical displacement of the fire monitor body. It should be understood that although this embodiment is described using a rotary motor drive as an example, in other embodiments, if the lifting mechanism is driven by a hydraulic cylinder, the redundant position detection unit 10 can also be set as a magnetostrictive displacement sensor to detect the stroke of the hydraulic cylinder piston rod or a flow meter to detect the flow rate of the oil pump, as long as it can indirectly characterize the expected motion state of the gun body from the driving side.

[0077] This layout provides the necessary physical foundation for a pressure-assisted discrimination-based data fusion fault-tolerant mechanism. When two position data conflict, the current pipeline pressure is used as a third-dimensional information for arbitration. The effectiveness of this arbitration logic depends precisely on the information difference formed by the main and redundant units being located at opposite ends of the transmission chain. If two sensors are installed at the same location or on the same component, their response patterns to faults or disturbances will be highly similar, making them difficult to distinguish through external physical quantities. The separation of the execution end and the drive end causes the two data streams to exhibit different sensitivities and response characteristics when facing different types of faults: the execution end data is more sensitive to load disturbances, wind load imbalances, and mechanical jamming, and its changes are often accompanied by abnormal fluctuations in pipeline pressure; the drive end data is more sensitive to electrical interference, drive failures, and control signal loss, and its anomalies are usually not directly related to the pressure state. It is this physical heterogeneity that enables the control module 8 to accurately identify which position data stream better matches the current mechanical equilibrium state based on the dynamic trend of the pressure data, thereby maintaining the continuous and safe operation of the system even in the event of a single-point failure. It should be understood that although this embodiment emphasizes the separate arrangement of the execution end and the drive end, in some special fire monitors 2, if it is not possible to directly install the sensor on the drive end, the redundant position detection unit 10 can also be set on the transition part in the middle of the transmission chain, such as the intermediate gear shaft or the connecting rod hinge point. As long as it can form effective kinematic decoupling with the execution end and provide an independent observation perspective, it should be covered within the protection scope of this invention.

[0078] In one possible implementation, see [reference] Figure 5 As shown, the fire extinguishing equipment 1 also includes: an operation instruction module 11; The operation instruction module 11 includes a manual control button 12 and a remote control unit 13; The manual control button 12 and the remote control unit 13 are respectively connected to the control module 8; the manual control button 12 and the remote control unit 13 are respectively used to provide action control commands to the control module 8; The control module 8 is used to receive and respond to the action control commands output by the manual control button 12 or the remote control unit 13 at the same time.

[0079] In practical applications, the manual control button 12 is typically located on the equipment itself or a nearby field control box, serving as a local physical interface suitable for equipment installation and commissioning, routine inspection and maintenance, or emergency on-site operation during communication link interruptions. The remote control unit 13, on the other hand, interfaces with the system via wireless or wired communication links, suitable for long-distance tactical deployment from the fire command center or collaborative operation of multiple equipment clusters. These two command sources complement each other in physical form and applicable scenarios, together forming a control system covering the entire operating radius. The manual control button 12 and the remote control unit 13 are respectively connected to the control module 8 and are used to provide action control commands to the control module 8. This connection relationship refers not only to the conduction of electrical signals but also to the independent design of the signal path.

[0080] In practical implementation, the manual control button 12 is preferably directly connected to the digital input port of the control module 8 via an independent hard-wired circuit to ensure a reliable physical control channel can still be established in extreme environments with severe wireless interference or network paralysis. The remote control unit 13 communicates with the control module 8 through a dedicated wireless receiving module or industrial bus interface, transmitting digital command packets containing encrypted check bits. This heterogeneous connection method ensures physical isolation between the two command sources at the transmission layer, avoiding the risk of simultaneous false triggering caused by common-mode interference.

[0081] More importantly, the control module 8 is used to receive and respond to the action control commands output by the manual control button 12 or the remote control unit 13 at the same time. It should be understood that the core technical meaning of receiving and responding at the same time here does not mean that the control module 8 can process two conflicting commands in parallel, but rather that the control module 8 ensures that within any given time slice, only one command source has actual control over the device. Specifically, this interlocking mechanism can be implemented through dual redundancy of hardware circuitry and software logic. At the hardware level, an electrical interlocking relay group can be set between the signal output terminals of the manual button and the remote receiver. When the manual button is pressed and activated, the signal input circuit of the remote control unit 13 is physically cut off, and vice versa, thereby fundamentally preventing the possibility of two signals entering the controller simultaneously. At the software level, when the control module 8 detects that two signals arrive successively within a very short time window, it locks the higher-priority command according to a preset priority strategy, typically setting on-site manual control to take precedence over remote control, and actively shields or discards the lower-priority command, while simultaneously feeding back "control occupancy" status information to the shielded party.

[0082] This embodiment fundamentally solves the problems of command conflicts and logical confusion that may occur in multi-source control scenarios through the aforementioned interlocking mechanism. In firefighting operations, if on-site manual and remote control are allowed to operate simultaneously, information asymmetry or reaction time differences among operators can easily lead to contradictory actions by the equipment. This can not only cause severe impact and damage to the mechanical transmission system but also delay valuable firefighting opportunities or even cause safety accidents. By forcibly establishing the uniqueness and certainty of control authority, a pure and reliable source of command input is provided, ensuring the stability of the entire safety closed loop.

[0083] It should be noted that the principle of the fire extinguishing equipment 1 provided in the embodiments of this application to solve the technical problem is similar to the control method of the fire extinguishing equipment 1 provided in the embodiments of this application.
