DETAILED DESCRIPTION

[0055] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0056] The fire truck control method of the present invention is described below with reference to Figures 1 to 5. The fire truck control method of the present invention is executed by an electronic device such as a controller or the hardware and / or software therein. The controller may be the controller of the fire truck itself, such as the vehicle controller, or a newly added controller. As shown in Figure 1, the fire truck control method of the present invention at least includes:

[0057] S101: Acquire an operation instruction and status data of each of the plurality of working systems of the fire truck.

[0058] Here, the fire truck can be a multifunctional fire truck that integrates some or all of the functions of fire extinguishing, decontamination, explosion suppression, lifting, power generation, demolition and rescue.

[0059] Operational instructions can be control commands entered by the operator, such as engine start commands, onboard firefighting device activation commands, offboard firefighting device activation commands, boom motion commands, outrigger motion commands, demolition commands, and power generation commands. The multiple operating systems of a fire truck may include some or all of the firefighting system, boom system, outrigger system, turret system, demolition system, and power generation system. For any of the multiple operating systems, the status data for that system may include the status of a control valve in that system or the hydraulic flow rate of that system.

[0060] S102. Based on the operating instructions and the status data of each of the working systems, when it is determined that the working condition execution conditions are met, one or more power branches corresponding to the target working system among the multiple working systems are controlled to be turned on, and / or the target working system is controlled to operate; wherein, each of the working systems is connected to the pump group through the corresponding power branch, the pump group includes multiple pump bodies, multiple power branches are correspondingly connected to multiple pump bodies, and multiple pump bodies are connected to the power input interface of the fire truck through the same power take-off device.

[0061] In this embodiment, for any of the multiple working systems, the working system may correspond to one or more power branches, and the working system is connected to the pump group via the corresponding power branches. The pump group may include multiple pump bodies, and the multiple power branches are correspondingly connected to the multiple pump bodies. Specifically, the multiple pump bodies in the pump group may be connected to the multiple power branches in a one-to-one correspondence, or a single pump body may be connected to multiple power branches simultaneously. The specific setting can be based on the power requirements of each working system and whether there is a need for different working systems to operate simultaneously.

[0062] In practice, for any of the multiple working systems, the power branch corresponding to the working system can correspond one-to-one with the drive device of the working system. That is, each drive device of the working system is provided on a corresponding power branch, so that when the power branch is turned on, the pump body connected to the power branch provides power to the corresponding drive device. It is understood that the power branch corresponding to the working system can also be directly connected to the working system, so that when the power branch corresponding to the working system is turned on, the corresponding pump body directly provides power to the working system.

[0063] The multiple pump bodies in the pump group are all connected to the power input interface of the fire truck through the same power take-off device. The power input interface of the fire truck can be connected to the fire truck's own power source, such as a motor or engine, or to an external power source. The pump body can be a hydraulic pump, which provides power to each working system by delivering hydraulic oil. For the pump bodies in the pump group that are connected to the power branches one by one, they can be connected to the corresponding power branches via a power output control valve. The power output control valve can be a hydraulic control valve to control the conduction or disconnection of the corresponding power branch through the power output control valve. For the pump bodies in the pump group that are simultaneously connected to multiple power branches, they can be connected to each power branch via a switching valve and / or a multi-way valve to control the conduction or disconnection of each power branch through the switching valve and / or the multi-way valve, thereby achieving multi-functional drive and being able to perform different working conditions simultaneously. Each pump body can be set according to the power required by the corresponding working system. When a single pump body is in operation, the other pump bodies in the pump group do not need to drive the load, generating less heat and achieving a reasonable distribution of power.

[0064] The operating condition execution condition indicates whether the operating condition corresponding to the operating instruction, i.e., the target operating condition, can be executed. Whether the operating condition execution condition is met can be determined based on the operating instruction and the status data of each operating system. For example, the target operating condition of the engine can be determined based on the operating instruction, and the current operating condition of the fire truck can be determined based on the status data of each operating system of the fire truck. Based on the interlocking relationships between the various operating conditions of the fire truck, whether the operating condition execution condition corresponding to the target operating condition is met can be determined.

[0065] If the working condition execution conditions are met, one or more power branches corresponding to the target working system among the multiple working systems can be controlled to be conductive, and / or the target working system can be controlled to operate, thereby providing power to the target working system through the power source connected to the power input interface to drive the target working system to operate. In other words, a single power take-off device can provide power to multiple working systems of the fire truck, greatly reducing the structural complexity of the fire truck. The target working system is the working system corresponding to the target working condition among the multiple working systems of the fire truck.

[0066] It is understandable that if the working condition execution conditions are not met, the current working condition can continue to be executed. In addition, an error can be reported, for example, through the display device of the fire truck or the remote control terminal to indicate that the corresponding operation instruction cannot be executed.

[0067] This embodiment obtains operating instructions and status data of each of the multiple working systems of the fire truck, and determines based on the operating instructions and the status data of each working system that when the working condition execution conditions are met, controls one or more power branches corresponding to the target working system in the multiple working systems to be turned on, and / or controls the operation of the target working system, wherein each working system is connected to the pump group through a corresponding power branch, the pump group includes multiple pump bodies, and the multiple power branches are correspondingly connected to the multiple pump bodies. The multiple pump bodies are connected to the power input interface of the fire truck through the same power take-off device, so that power can be provided to the multiple working systems of the fire truck through a set of power take-off devices, which greatly reduces the structural complexity of the fire truck and thereby achieves a significant reduction in the cost of the fire truck.

[0068] In an exemplary embodiment, the working conditions of the fire truck include a firefighting working condition when boarding the truck, a firefighting working condition when getting off the truck, a non-firefighting working condition when boarding the truck, and a non-firefighting working condition when getting off the truck;

[0069] As shown in FIG2 , based on the operation instruction and the status data of each of the working systems, determining whether the working condition execution condition is met includes:

[0070] S201, determining a target operating condition of the fire truck based on the operation instruction, and determining a current operating condition of the fire truck based on status data of each of the working systems;

[0071] S202. Based on the target working condition, the current working condition, and the preset interlocking relationship between the various working conditions of the fire truck, determine whether the working condition execution conditions are met; wherein, the fire-fighting working condition for getting on the vehicle is interlocked with the fire-fighting working condition for getting off the vehicle, and the non-fire-fighting working condition for getting on the vehicle is interlocked with the non-fire-fighting working condition for getting off the vehicle.

[0072] In this embodiment, both onboard and offboard firefighting conditions can be performed by the firefighting system. The firefighting system can include firefighting equipment. For example, the firefighting equipment can include an onboard firefighting device installed on the onboard vehicle, such as a first spray cannon, and can also include offboard firefighting equipment installed on the offboard vehicle, such as a second spray cannon and / or a spray gun. Onboard firefighting conditions can be performed by the onboard firefighting device, and offboard firefighting conditions can be performed by the offboard firefighting device. Onboard non-firefighting conditions can be performed by the boom system and / or the demolition system, while offboard non-firefighting conditions can be performed by the outrigger system.

[0073] When determining whether the working condition execution conditions are met, the target working condition of the fire truck can be determined based on the operating instruction. For example, the working condition corresponding to the operating instruction can be determined based on the preset correspondence between the operating instruction and the working condition, and used as the target working condition. The target working condition is the working condition to be executed.

[0074] At the same time, the current working condition of the fire truck can also be determined based on the status data of each working system. For example, based on the status data of each working system, it can be determined whether each working system is currently in a working state or a non-working state, and the working condition corresponding to the working system that is currently in a working state can be used as the current working condition of the fire truck to ensure the reliability of the determination result of the current working condition.

[0075] After obtaining the target operating condition and the current operating condition, it is possible to further determine whether the operating condition execution condition is satisfied based on the target operating condition, the current operating condition, and the preset interlocking relationship between the various operating conditions of the fire truck. For example, based on the preset interlocking relationship between the various operating conditions of the fire truck, the target operating condition and the current operating condition can be matched to determine whether there is an interlocking relationship between the target operating condition and the current operating condition. If there is an interlocking relationship between the target operating condition and the current operating condition, it indicates that the operating condition execution condition is not satisfied. If there is no interlocking relationship between the target operating condition and the current operating condition, it indicates that the operating condition execution condition is satisfied.

[0076] Among them, the fire-fighting condition for getting on the vehicle and the fire-fighting condition for getting off the vehicle are interlocked, and the non-fire-fighting condition for getting on the vehicle and the non-fire-fighting condition for getting off the vehicle are interlocked, that is, when executing the fire-fighting condition for getting on the vehicle, the fire-fighting condition for getting off the vehicle is not allowed to be executed, when executing the fire-fighting condition for getting off the vehicle, the fire-fighting condition for getting on the vehicle is not allowed to be executed, and when executing the non-fire-fighting condition for getting off the vehicle, the non-fire-fighting condition for getting on the vehicle is not allowed to be executed, thereby effectively meeting the power requirements during the operation of the fire truck and improving the safety and convenience of operation during the fire-fighting operation.

[0077] It is understandable that the operating conditions of a fire truck can also include power generation conditions, which are performed by a power generation system. The power generation system can include a motor, which can be connected to the corresponding pump body in the pump group through a power branch, so that the corresponding pump body can independently drive the power generation system to perform power generation operations. At the same time, the power generation conditions are non-interlocked with the onboard firefighting conditions, the offboard firefighting conditions, the onboard non-firefighting conditions, and the offboard non-firefighting conditions. That is, the power generation operation is not restricted by the onboard and offboard interlocking. Therefore, the power generation conditions can be performed during the execution of the onboard firefighting conditions, the offboard firefighting conditions, the onboard non-firefighting conditions, and the offboard non-firefighting conditions, thereby ensuring the reliability of the fire truck. In addition, if the firefighting system and the power generation system do not need to work simultaneously, the power generation system can also be driven by the pump body connected to the firefighting system.

[0078] In an exemplary embodiment, the working condition of the fire truck also includes an internal circulation working condition, and the plurality of working systems include a fire fighting system, the fire fighting system including a fire fighting device and one or more liquid branches arranged between the liquid inlet of the fire fighting device and the liquid input interface of the fire fighting truck, each of the liquid branches is provided with a fire fighting pump and a pressure regulating device, the pressure regulating device is arranged between the liquid inlet of the fire fighting device and the corresponding fire fighting pump, and the pressure regulating device is also connected to the water inlet of the corresponding fire fighting pump through a reflux branch;

[0079] As shown in FIG3 , the controlling of one or more power branches corresponding to a target working system among the plurality of working systems to be turned on, and / or controlling the operation of the target working system, includes:

[0080] S301, when the target operating condition is the internal circulation operating condition, controlling all the power branches corresponding to the fire protection system to be turned on;

[0081] S302: Obtain pressure data of the liquid inlet of the fire-fighting device. If the pressure data is greater than or equal to a preset pressure value, control the pressure regulating devices in each liquid branch of the fire-fighting system to open.

[0082] In this embodiment, the firefighting system may include a firefighting device and one or more liquid branches disposed between a liquid inlet of the firefighting device and a liquid input interface of a fire truck. Liquid output from each liquid branch is collected at the liquid inlet of the firefighting device, allowing the firefighting device to perform firefighting operations. The liquid input interface may include a water input interface and a foam input interface, and water or a mixture of water and foam enters each liquid branch.

[0083] For any liquid branch, a fire pump and a pressure regulating device are provided on the liquid branch. The pressure regulating device can be a pressure regulating valve. The pressure regulating valve can include a first interface, a second interface and a third interface. The first interface is connected to the output port of the fire pump in the liquid branch, the second interface can be connected to the liquid inlet of the fire protection device through a one-way valve, and the third interface can be connected to the water inlet of the fire pump in the liquid branch through a reflux branch to form an internal circulation loop.

[0084] One or more fire pumps can be connected one-to-one with one or more driving devices of the fire protection system. The driving device of the fire protection system can be a hydraulic motor. Each hydraulic motor is connected to a power branch, and the corresponding power branches of the fire protection system are respectively connected to different pump bodies, that is, different hydraulic motors provide liquid pressure energy through different pump bodies.

[0085] The working condition of the fire truck may also include an internal circulation working condition, which is executed by the fire protection system. The internal circulation working condition is the circulation of the liquid pumped by the fire pump in the internal circulation loop including the fire pump.

[0086] If the target working condition is the internal circulation working condition, all power branches corresponding to the fire protection system can be controlled to be turned on, so that each fire pump can be powered by each power branch respectively, so that the liquid input by the liquid input interface can be pumped to the liquid inlet of the fire protection device through each fire pump.

[0087] A pressure collection device, such as a pressure sensor, can be installed at the liquid inlet of the fire-fighting device. This device collects pressure data at the liquid inlet. The pressure data collected by the pressure collection device can be acquired in real time. If the pressure data is greater than or equal to a preset pressure value, the pressure regulating device in each liquid branch can be controlled to open, thereby transferring the liquid pumped by the fire pump in the corresponding liquid branch to the water inlet of the fire pump via the return branch, thereby achieving internal circulation.

[0088] Among them, the internal circulation working condition can be the initial working condition of the fire protection system. When the fire truck receives a fire preparation instruction or a start-up instruction, the internal circulation working condition can be executed to increase the pressure of the liquid inlet of the fire protection device to a preset pressure value in advance. Therefore, when receiving an on-vehicle fire protection device action instruction or an off-vehicle fire protection device action instruction, the internal circulation working condition can be directly switched to the on-vehicle fire protection working condition or the off-vehicle fire protection working condition, which effectively improves the working condition switching efficiency and greatly improves the fire protection efficiency.

[0089] At the same time, when the pressure at the liquid inlet of the fire-fighting device reaches a preset pressure value, the present application can automatically release the pressure to the water inlet of the fire pump by opening the pressure regulating device, without the need for a tank water filling valve and its connected pipes, with a simple structure and low cost; in addition, by releasing the pressure to the water inlet of the fire-fighting pump, it can effectively avoid corrosion and pollution caused by the mixed liquid entering the tank body or water source.

[0090] It is understood that a first flow collection device may also be provided at the liquid inlet of the fire-fighting device. The first flow collection device may be a flow sensor, and the first flow collection device is used to collect flow data at the liquid inlet of the fire-fighting device. It is also possible to obtain the flow data collected by the first flow collection device in real time when executing the on-board fire-fighting condition or the off-board fire-fighting condition, and determine whether to switch to the internal circulation condition based on the flow data at the liquid inlet of the fire-fighting device. For example, when the flow data at the liquid inlet of the fire-fighting device is less than a preset threshold, the device switches to the internal circulation condition. When the flow data at the liquid inlet of the fire-fighting device is greater than or equal to the preset threshold, the device maintains the current condition. It is also understandable that it is also possible to determine, based on an operation instruction, whether to switch to the internal circulation condition when the on-board fire-fighting condition or the off-board fire-fighting condition is completed.

[0091] In an exemplary embodiment, the fire-fighting device includes an on-vehicle fire-fighting device, and the on-vehicle fire-fighting device includes a first spray cannon;

[0092] As shown in FIG4 , the controlling of one or more power branches corresponding to a target working system among the plurality of working systems to be turned on, and / or controlling the operation of the target working system, includes:

[0093] S401: If the target operating condition is the on-vehicle firefighting operating condition and the current operating condition is the internal circulation operating condition, control the first control valve corresponding to the first spray cannon to open; wherein the first control valve is disposed in a pipeline between the first spray cannon and the liquid inlet of the firefighting device;

[0094] S402: When it is determined based on the operation instruction that the operation of the on-vehicle fire-fighting device is completed, the first control valve is controlled to close, and the internal circulation working condition is executed.

[0095] In this embodiment, the on-board fire-fighting device may include a first spray cannon installed on the vehicle, for example, it may be installed on an arm to achieve high-rise firefighting. In the related art, fire trucks usually use high-pressure fine water mist with a particle size distribution of less than 200 microns, and usually adopt a dismounting method. There is no high-rise spraying function, a low working height, and a short range. In this embodiment, the first spray cannon is used to spray high-pressure spray, which can form a high-pressure spray with a particle size distribution of 400-1000 microns. The high-pressure spray has a higher pressure, a longer range, and faster heat exchange, thereby effectively improving firefighting efficiency. Among them, the performance requirements of the high-pressure spray sprayed by the first spray cannon can be met by adjusting the pressure of the liquid input to the first spray cannon.

[0096] A first control valve may be provided on the pipeline between the first spray cannon and the liquid inlet of the fire-fighting device, for example, a first cannon control valve, which is used to control the on-off of the pipeline between the first spray cannon and the liquid inlet of the fire-fighting device.

[0097] When the target operating condition is the on-vehicle fire-fighting operating condition and the current operating condition is the internal circulation operating condition, the first control valve corresponding to the first spray cannon can be controlled to open. At the same time, if the pressure regulating devices on each liquid branch are in the open state, the pressure regulating devices on each liquid branch can also be controlled to close, so that the liquid input from the liquid input interface is pumped to the first spray cannon through the fire pump on each liquid branch, thereby realizing rapid switching from the internal circulation operating condition to the on-vehicle fire-fighting operating condition.

[0098] When executing the on-vehicle fire-fighting working condition, the operation instructions can be obtained in real time. If it is determined according to the operation instructions that the operation of the on-vehicle fire-fighting device is completed, the first control valve corresponding to the first spray cannon can be controlled to close, and the internal circulation working condition can be executed, so that when the on-vehicle fire-fighting working condition or the off-vehicle fire-fighting working condition is executed again, the working condition can be switched quickly.

[0099] In an exemplary embodiment, the firefighting apparatus includes one or more dismounted firefighting apparatus;

[0100] As shown in FIG5 , the controlling of one or more power branches corresponding to a target working system among the plurality of working systems to be turned on, and / or controlling the operation of the target working system, includes:

[0101] S501: If the target operating condition is the fire-fighting condition for getting off the vehicle and the current operating condition is the internal circulation condition, control the second control valve corresponding to the target working device to open; wherein the target working device is the fire-fighting device for getting off the vehicle corresponding to the target operating condition; and the second control valve is disposed on a pipeline between the corresponding fire-fighting device for getting off the vehicle and a liquid inlet of the fire-fighting device;

[0102] S502: When it is determined based on the operation instruction that the target working device operation is completed, the second control valve corresponding to the target working device is controlled to close, and when all the target working devices operations are completed, the inner circulation working condition is executed.

[0103] In this embodiment, the firefighting equipment may further include one or more off-vehicle firefighting devices. For example, the off-vehicle firefighting equipment may include a second spray cannon and / or a spray gun disposed on the off-vehicle. The off-vehicle firefighting operating conditions may include an off-vehicle gun operating condition corresponding to the second spray cannon and / or a gun operating condition corresponding to the spray gun. The second spray cannon may have the same performance as the first spray cannon, and the number of spray guns may be one or more. The spray guns may have a smaller spray pressure and range than the first and second spray cannons.

[0104] A second control valve, for example, a second cannon control valve, may be provided on the pipeline between the second spray cannon and the liquid inlet of the fire-fighting device. The second cannon control valve is used to control the on-off of the pipeline between the second spray cannon and the liquid inlet of the fire-fighting device. A second control valve, for example, a gun control valve, may be provided on the pipeline between the spray gun and the liquid inlet of the fire-fighting device. The gun control valve is used to control the on-off of the pipeline between the spray gun and the liquid inlet of the fire-fighting device.

[0105] If the target operating condition is the firefighting condition for disembarking and the current operating condition is the internal circulation condition, the second control valve corresponding to the target working device can be controlled to open, and the target working device becomes the firefighting device for disembarking corresponding to the target operating condition. At the same time, if the pressure regulating devices on each liquid branch are open, the pressure regulating devices on each liquid branch can also be controlled to close, allowing the fire pumps on each liquid branch to pump the liquid input interface to the target working device, thus achieving a rapid switch from the internal circulation condition to the firefighting condition for disembarking.

[0106] When executing the fire-fighting condition for getting off the vehicle, the operation instructions can be obtained in real time. If it is determined according to the operation instructions that the operation of the target working device is completed, the second control valve corresponding to the target working device can be controlled to close. Moreover, when the operation of all target working devices is completed, the internal circulation condition is executed so that when the fire-fighting condition for getting on the vehicle or getting off the vehicle is executed again, the working condition can be switched quickly.

[0107] In an exemplary embodiment, the off-vehicle firefighting device includes a plurality of spray guns, each of which is disposed on a different spray gun line. Each of the spray gun lines is connected to a spray gun trunk line, which is connected to a liquid inlet of the firefighting device. The second control valve corresponding to each spray gun is disposed on the spray gun trunk line. The firefighting system includes a plurality of fire pumps, each of which is connected to a plurality of power branches in a one-to-one correspondence.

[0108] If the target working device is the spray gun, after controlling the second control valve corresponding to the spray gun to open, the method further includes:

[0109] Acquiring flow data on each of the spray gun lines, and determining the number of the spray guns in an open state based on a comparison result of the flow data on each of the spray gun lines with a preset flow value;

[0110] Based on the number of the spray guns in the open state, a target branch among the plurality of power branches is determined, and the power branches other than the target branch among the plurality of power branches corresponding to the fire fighting system are controlled to be disconnected.

[0111] In this embodiment, the off-vehicle firefighting device may include multiple spray guns, each of which may be arranged on a different spray gun line. Each spray gun line is connected to a corresponding spray gun at one end and to a spray gun main line at the other end. The spray gun main line is connected to a liquid inlet of the firefighting device at one end and to each spray gun line at the other end. The second control valve corresponding to each spray gun is arranged on the spray gun main line. The firefighting system includes multiple fire pumps, each of which is connected to a plurality of power branches in a one-to-one correspondence, so that each power branch drives the corresponding fire pump. That is, when the second control valve corresponding to a spray gun is opened, liquid can be pumped to each spray gun line via the multiple fire pumps.

[0112] If the target working device is a spray gun, after controlling the second control valve corresponding to the spray gun to open, flow data on each spray gun line can be further obtained, and based on the comparison result of the flow data on each spray gun line with the preset flow value, the number of spray guns in the open state can be determined.

[0113] In implementation, a second flow rate collection device, which can be a flow sensor, can be provided on each spray gun circuit. The second flow rate collection device is used to collect flow rate data on the corresponding spray gun circuit. For any of the multiple spray gun circuits, if the flow rate data on the spray gun circuit is greater than or equal to a preset flow rate value, it indicates that the spray gun connected to the spray gun circuit is in the open state. If the flow rate data on the spray gun circuit is less than the preset flow rate value, it indicates that the spray gun connected to the spray gun circuit is in the closed state. This allows automatic determination of the open and closed states of each spray gun, and the number of spray guns in the open state can be determined based on the open and closed states of each spray gun.

[0114] After determining the number of spray guns in the turned-on state, the target branch among the multiple power branches can be determined based on the number of spray guns in the turned-on state. For example, the target branch can be determined based on the number of spray guns in the turned-on state and a preset correspondence between the number of spray guns in the turned-on state and the target branch.

[0115] After determining the target branch, the power branches other than the target branch in the multiple power branches corresponding to the fire protection system can be further controlled to be disconnected, so that the start and stop status of the fire pump can be adjusted according to the number of spray guns in the open state, and the flow rate of the spray gun main line can be controlled without adjusting the engine speed, which greatly improves the switching speed between single-gun operation mode and multi-gun operation mode.

[0116] It is understood that if the power source is an engine, the engine speed can be controlled to a preset speed during the onboard and offboard firefighting conditions. Furthermore, a speed acquisition device can be provided on each fire pump to acquire the speed of the corresponding fire pump, determine the target engine speed based on the fire pump speed, and control the engine speed based on the target speed.

[0117] In an exemplary embodiment, the plurality of working systems further include one or more on-board non-firefighting working systems corresponding to the on-board non-firefighting working condition, and a disembarkation non-firefighting working system corresponding to the disembarkation non-firefighting working condition; wherein each power branch corresponding to the on-board non-firefighting working system is connected to a switching valve via a first multi-way valve, and each power branch corresponding to the disembarkation non-firefighting working system is connected to the switching valve via a second multi-way valve, and the switching valve is connected to a target pump body in the pump group;

[0118] The controlling of one or more power branches corresponding to a target working system among the plurality of working systems to be turned on, and / or controlling the operation of the target working system, includes:

[0119] If the target operating condition is the non-firefighting operating condition for boarding the vehicle, controlling the switching valve to switch to the first multi-way valve, and, based on the control operation corresponding to the target working system, determining a first target valve port among the output valve ports of the first multi-way valve, and controlling the first target valve port to open;

[0120] and / or,

[0121] If the target working condition is the non-firefighting working condition for getting off the vehicle, the switching valve is controlled to switch to the second multi-way valve, and based on the control operation corresponding to the target working system, the second target valve port among the output valve ports of the second multi-way valve is determined, and the second target valve port is controlled to open.

[0122] In this embodiment, the multiple working systems also include one or more non-firefighting working systems for getting on the vehicle corresponding to the non-firefighting working conditions and one or more non-firefighting working systems for getting off the vehicle corresponding to the non-firefighting working conditions.

[0123] The power branches corresponding to the boarding non-firefighting working system can be connected to the switching valve via a first multi-way valve, and the power branches corresponding to the disembarking non-firefighting working system can be connected to the switching valve via a second multi-way valve. The switching valve is connected to the target pump body in the pump group. That is, the target pump body is simultaneously connected to all power branches corresponding to the boarding non-firefighting working system and the disembarking non-firefighting working system via the switching valve, the first multi-way valve, and the second multi-way valve. The target pump body is the pump body in the pump group that is connected to the switching valve.

[0124] The on-vehicle non-firefighting work system may include a boom system and / or a demolition system, and each driving device in the on-vehicle non-firefighting work system or the on-vehicle non-firefighting work system may be respectively connected to different output valve ports of the first multi-way valve. Among them, the driving device of the boom system may include a slewing motor and boom cylinders corresponding to each boom in the boom system, so as to drive the boom system to perform variable amplitude actions (such as unfolding, retracting, extending, retracting, etc.) through each boom cylinder, and drive the boom system to rotate through the slewing motor, and each driving device of the boom system may be respectively connected to different output valve ports of the first multi-way valve. The demolition system may include demolition accessories, which are directly connected to the output valve port of the first multi-way valve, and the input valve port of the first multi-way valve is connected to the switching valve.

[0125] The non-firefighting disembarkation system may include an outrigger system. The outrigger system's drive devices may include corresponding outrigger cylinders for each outrigger in the system, which drive corresponding outrigger movements, such as deployment, retraction, lowering, and retraction. Each outrigger system drive device may be connected to a different output valve port of a second multi-way valve, with the input valve port of the second multi-way valve connected to the switching valve. The first and second multi-way valves may be bus-type or current-type multi-way valves.

[0126] If the target working condition is a non-firefighting working condition for getting on a vehicle, the switching valve can be controlled to switch to the first multi-way valve, and based on the operator's control operation of the target working system in one or more non-firefighting working systems for getting on a vehicle, the first target valve port among the output valve ports of the first multi-way valve is determined, and then the first target valve port is controlled to open to drive the target working system to perform the action corresponding to the control operation. In the process of determining the first target valve port, if the target working system is a boom system, the target driving device among the driving devices of the boom system can be further determined based on the control operation, and the first target valve port among the output valve ports of the first multi-way valve is determined based on the corresponding relationship between the output valve ports in the first multi-way valve and the working system and / or the driving device; if the target working system is a demolition system, the first target valve port among the output valve ports of the first multi-way valve can be directly determined based on the corresponding relationship between the output valve ports in the first multi-way valve and the working system and / or the driving device.

[0127] If the target working condition is a non-firefighting working condition for getting off the vehicle, the target working system is a non-firefighting working system for getting off the vehicle, and the switching valve can be controlled to switch to the second multi-way valve, and based on the operator's control operation on the target working system, the second target driving device in each driving device of the target working system is determined, and according to the correspondence between each output valve port in the second multi-way valve and the driving device, the second target valve port in each output valve port of the second multi-way valve is determined, and then the second target valve port is controlled to open to drive the target working system to perform the action corresponding to the control operation, thereby further structurally avoiding the simultaneous execution of the non-firefighting working condition for getting on the vehicle and the non-firefighting working condition for getting off the vehicle, and thus effectively meeting the power requirements of the non-firefighting working system for getting on the vehicle and the non-firefighting working system for getting off the vehicle, and improving the safety and convenience of operation during the operation. It is understandable that the control operation can be input by the operator through a remote control or a hydraulic handle.

[0128] The fire truck control device provided by the present invention is described below.

[0133] It should be noted that Figure 7 uses an example including n (n>2) pump bodies 705 and m (m>1) working systems 704.

For example, multiple working systems 704 can be connected to one pump body 705 in the pump group 702 through corresponding power branches. Figure 7 only uses one working system 704 connected to two different pump bodies 705 in the pump group 702 through two power branches, and one working system 704 connected to one pump body 705 in the pump group 702 through one power branch as an example.

When the pump body 705 is simultaneously connected to multiple power branches, it can be connected to each power branch via a switching valve and / or a multi-way valve, thereby controlling the conduction or disconnection of each corresponding power branch via the switching valve and / or the multi-way valve.
