[0035] As Figure 1 shown, schematically shows a flowchart of a control method for a water supply system in an embodiment of the present application. As Figure 1 shown, in an embodiment of the present application, a control method for a water supply system is provided, including the following steps:

[0036] Step 101, obtain the water supply flow rate of the water supply vehicle and the water outlet flow rate of each water receiving vehicle;

[0037] Step 102, determine the total water outlet flow rate according to the water outlet flow rates of all the water receiving vehicles;

[0038] Step 103, when the water supply flow rate is less than the total effluent flow rate, reduce the effluent flow rate of the water receiving vehicle so that the error value between the water supply flow rate and the total effluent flow rate is within a preset error range;

[0039] Step 104, when the water supply flow rate is greater than the total effluent flow rate, reduce the water supply flow rate of the water supply vehicle so that the error value between the water supply flow rate and the total effluent flow rate is within a preset error range, and adjust the valve opening of the water supply valve corresponding to each water receiving vehicle so that the error between the water supply flow rate of the water supply vehicle for each water receiving vehicle and the effluent flow rate of the water receiving vehicle is within a preset error range.

[0040] The water supply system includes at least one water supply vehicle and one water receiving vehicle. A water supply valve is connected between each water receiving vehicle and the water supply vehicle, and the water supply vehicle supplies water to the water receiving vehicle through the water supply valve. The processor can obtain the water supply flow rate of the water supply vehicle and the effluent flow rate of each water receiving vehicle, determine the total effluent flow rate according to the obtained effluent flow rate of each water receiving vehicle, compare the water supply flow rate of the water supply vehicle with the total effluent flow rate. When it is determined that the water supply flow rate is less than the total effluent flow rate, the processor can reduce the effluent flow rate of the water receiving vehicle by reducing the engine speed of the water receiving vehicle, so that the error between the water supply flow rate and the total effluent flow rate is within a preset error range.

[0041] When the water supply flow rate is greater than the total effluent flow rate, the processor can control and reduce the water supply flow rate of the water supply vehicle so that the error value between the water supply flow rate and the total effluent flow rate is within a preset error range. The processor can also adjust the valve opening of the water supply valve corresponding to each water receiving vehicle so that the error between the water supply flow rate of the water supply vehicle for each water receiving vehicle and the effluent flow rate of each water receiving vehicle is within a preset error range. For example, assume that the water supply flow rate of the water supply vehicle to the first water receiving vehicle is Q1, the water supply flow rate to the second water receiving vehicle is Q2, the water supply flow rate to the third water receiving vehicle is Q3, the effluent flow rate of the first water receiving vehicle is Q4, the effluent flow rate of the second water receiving vehicle is Q5, and the effluent flow rate of the third water receiving vehicle is Q6. The sum of Q1, Q3, and Q3 is the water supply flow rate Q of the water supply vehicle. Through the valve opening of the water supply valve corresponding to each water receiving vehicle, make Q1 = Q4, Q2 = Q5, and Q3 = Q6.

[0042] In one embodiment, before obtaining the water supply flow rate of the water supply vehicle and the effluent flow rate of each water receiving vehicle, obtain the water storage level and fuel level in the water supply vehicle; determine the available water supply duration of the water supply vehicle according to the water storage level and fuel level in the water supply vehicle; when the available water supply duration is greater than a first preset duration, determine that the water supply vehicle has completed the water supply preparation operation for the water receiving vehicle; when the available water supply duration is less than the first preset duration, determine that the water supply vehicle has not completed the water supply preparation operation for the water receiving vehicle.

[0043] Before the processor obtains the water supply flow rate of the water supply vehicle and the water discharge flow rate of each water receiving vehicle, the processor can obtain the water storage level and fuel level in the water supply vehicle. The processor can determine the available water supply duration of the water supply vehicle based on the water storage level and fuel level in the water supply vehicle. When the processor determines that the available water supply duration of the water supply vehicle is greater than the first preset duration set by the processor, the processor can determine that the water supply vehicle has completed the water supply preparation operation for the water receiving vehicle. If the processor determines that the available water supply duration of the water supply vehicle is less than the first preset duration, the processor determines that the water supply vehicle has not completed the water supply preparation operation for the water receiving vehicle, and the water supply vehicle cannot supply water to the water receiving vehicle.

[0044] In one embodiment, obtain the water storage level in the water supply vehicle; when the water storage level is lower than the preset level value, control the engine speed of the water supply vehicle to decrease to the vehicle idle speed of the water supply vehicle to reduce the water supply flow rate of the water supply vehicle; send an adjustment notice to the water receiving vehicle so that the water receiving vehicle reduces the water discharge flow rate according to the adjustment notice and the water storage level in the water receiving vehicle.

[0045] The processor can obtain the water storage level in the water supply vehicle. When the processor determines that the water storage level in the water supply vehicle is lower than the preset level value set by the processor, the processor can control the engine speed of the water supply vehicle to decrease to the vehicle idle speed of the water supply vehicle to reduce the water supply flow rate of the water supply vehicle. The processor determines that the water storage level in the water supply vehicle is lower than the preset level value set by the processor, indicating that the water storage capacity of the water supply vehicle is insufficient. Therefore, it is necessary to control the engine speed of the water supply vehicle to decrease to the vehicle idle speed of the water supply vehicle and send an adjustment notice to the water receiving vehicle. After receiving the adjustment notice from the water supply vehicle, the water receiving vehicle can obtain its own water storage level and reduce the water discharge flow rate of the water receiving vehicle according to the adjustment notice and the water storage level in the water receiving vehicle.

[0046] In one embodiment, sending an adjustment notice to the water receiving vehicle so that the water receiving vehicle reduces the water discharge flow rate according to the adjustment notice and the water storage level in the water receiving vehicle includes: sending an adjustment notice to the water receiving vehicle so that the water receiving vehicle adjusts the engine speed of the water receiving vehicle according to the adjustment notice and the water storage level in the water receiving vehicle, so that the water discharge duration of the water receiving vehicle when discharging water at a preset speed is greater than the second preset duration.

[0047] After the processor controls the water supply vehicle to reduce the engine speed to the vehicle idle speed to reduce the water supply flow rate of the water supply vehicle, it can send an adjustment notice to the water receiving vehicle. The water receiving vehicle can obtain the water storage level of its own vehicle and adjust the engine speed of the water receiving vehicle according to the water storage level in the water receiving vehicle, that is, adjust the water output flow rate of the water receiving vehicle. By adjusting the water output flow rate of the water receiving vehicle, on the basis of the existing water storage level of the water receiving vehicle itself, the water output duration of the water receiving vehicle when the water output is at the preset speed can be made longer than the second preset duration set by the processor. For example, assuming that the second preset duration set by the processor is 3 minutes, after the water receiving vehicle receives the adjustment notice, the processor can adjust the engine speed of the water receiving vehicle according to the water storage level of the water receiving vehicle, so that the water receiving vehicle can output water at the preset speed and the water output duration is longer than 3 minutes.

[0048] In one embodiment, determining the total water output flow rate according to the water output flow rates of all the water receiving vehicles includes: detecting whether a water receiving vehicle has a fault; in the case of determining that at least one water receiving vehicle has a fault, determining the total water output flow rate according to the water output flow rates of the water receiving vehicles without faults.

[0049] In one embodiment, control the water supply valve corresponding to the water receiving vehicle with a fault to close, and control the engine speed of the water receiving vehicle with a fault to be reduced to the vehicle idle speed.

[0050] The processor can determine the total water output of the water receiving vehicles according to the water output flow rates of all the water receiving vehicles. The processor can perform fault detection on each water receiving vehicle. When the processor detects that a water receiving vehicle has a fault, control the water supply valve corresponding to the water receiving vehicle with a fault to close, and control the engine speed of the water receiving vehicle with a fault to be reduced to the vehicle idle speed of that vehicle. At this time, the processor can determine the total water output flow rate of the water receiving vehicles according to the water output flow rates of the water receiving vehicles without faults.

[0051] In one embodiment, obtain the fuel level value and unit fuel consumption of each water receiving vehicle; determine the available working duration of each water receiving vehicle according to the fuel level value and unit fuel consumption of each water receiving vehicle; determine the target water supply flow rate of the water supply vehicle for each water receiving vehicle according to the available working duration of each water receiving vehicle; during the water supply operation of the water supply vehicle, adjust the water supply valve corresponding to each water receiving vehicle according to the target water supply flow rate of each water receiving vehicle.

[0052] The processor can obtain the fuel level value and unit fuel consumption of each water receiving vehicle, determine the available working duration of each water receiving vehicle based on the fuel level value and unit fuel consumption of each water receiving vehicle, and determine the target water supply flow rate of the water supply vehicle for each water receiving vehicle according to the available working duration of each water receiving vehicle. For example, assuming that the available working durations of each water receiving vehicle are equal, the target water supply flow rates of the water supply vehicle for each water receiving vehicle are also equal. During the water supply operation of the water supply vehicle, adjust the water supply valve corresponding to each water receiving vehicle according to the target water supply flow rate of each water receiving vehicle. For example, assuming that the target water supply flow rates of the water supply vehicle for each water receiving vehicle are equal, control the valve opening degrees of the water supply valves corresponding to each water receiving vehicle to be equal.

[0053] In one embodiment, determining the target water supply flow rate of the water supply vehicle for each water receiving vehicle according to the available working duration of each water receiving vehicle includes: when the difference between the available working durations of any two water receiving vehicles is within a preset difference range, determining the target water supply flow rate of each water receiving vehicle according to the number of water receiving vehicles and the total water output flow rate, where the target water supply flow rates between any two water receiving vehicles are the same; when the difference between the available working durations of at least two water receiving vehicles exceeds the preset difference range, determining the flow coefficient of each water receiving vehicle; and determining the target water supply flow rate of each water receiving vehicle according to the flow coefficient of each water receiving vehicle.

[0054] The processor can obtain the available working duration of each water receiving vehicle and compare the available working durations of any two water receiving vehicles. When the difference between the available working durations of any two water receiving vehicles is within the preset difference range set by the processor, the processor can determine the target water supply flow rate of each water receiving vehicle according to the number of water receiving vehicles and the total water output flow rate, where the target water supply flow rates between any two water receiving vehicles are the same. That is to say, when the available working durations of each water receiving vehicle are equal, the processor can determine that the target water supply flow rates of each water receiving vehicle are the same. When the processor determines that the difference between the available working durations of at least two water receiving vehicles exceeds the preset difference range, that is, when the available working durations of all water receiving vehicles are not equal, the processor can determine the flow coefficient of each water receiving vehicle and determine the target water supply flow rate of each water receiving vehicle according to the flow coefficient of each water receiving vehicle.

[0055] In one embodiment, determining the flow coefficient of each water receiving vehicle includes: obtaining the working parameters of each water receiving vehicle, where the working parameters include the water output parameters of the water receiving vehicle and the environmental parameters of the task site where the water receiving vehicle is located; determining the contribution value of each water receiving vehicle for the task to be performed in the task site according to the water output parameters and environmental parameters of each water receiving vehicle; and determining the flow coefficient of each water receiving vehicle according to the contribution value of each water receiving vehicle.

[0056] When the processor determines that the available working hours of not all water receiving vehicles are equivalent, the processor can obtain the flow coefficient of each water receiving vehicle. The processor can obtain the working parameters of each water receiving vehicle. The working parameters can include the water output parameters of the water receiving vehicle and the environmental parameters of the task site where the water receiving vehicle is located. For example, the water output parameters of the vehicle can include the water output flow of the vehicle, the spraying distance of the vehicle, etc. The environmental parameters can include the distance of the vehicle from the fire center, the position of the vehicle relative to the fire center, the landing position of the vehicle's water spray, etc. The processor can determine the contribution value of each water receiving vehicle for the task to be performed at the task site based on the above parameters, and determine the flow coefficient of each water receiving vehicle based on the contribution value of each water receiving vehicle. The processor can also receive the flow coefficient input by the operator and determine the target water supply flow of each water receiving vehicle based on the flow coefficient input by the operator. For example, assume there are three water receiving vehicles. The processor determines, by receiving the flow coefficient input by the operator, that the coefficient of the first water receiving vehicle is 0.4, the coefficient of the second water receiving vehicle is 0.4, and the coefficient of the third water receiving vehicle is 0.2. Based on the flow coefficient of each water receiving vehicle, the processor can determine the target water supply flow of each water receiving vehicle. The processor can adjust the valve opening of the water supply valve for each water receiving vehicle according to the target water supply flow of each water receiving vehicle, so as to adjust the water supply flow of each water receiving vehicle.

[0057] In the above solution, by confirming the available working hours of the water receiving vehicles, the flow coefficient of each water receiving vehicle is confirmed, and the valve opening of the water supply valve of each water receiving vehicle is determined based on the confirmed flow coefficient. The flow coefficient of each water receiving vehicle can also be determined based on the contribution value of each water receiving vehicle for the task site, and the valve opening of the water supply valve is adjusted according to the determined flow coefficient, so as to determine different water supply flows for different water receiving vehicles. The processor can reasonably allocate resources according to the available working hours of the water receiving vehicles, allocate different water supply flows according to the available working hours of each water receiving vehicle, so that the water supply resources can be maximally utilized. At the same time, the processor can also determine the water supply flow of each water receiving vehicle based on the contribution value of each water receiving vehicle for the task site, so as to support the maximization of the rescue efficiency of the water receiving vehicles and avoid waste of resources.

[0058] In one embodiment, as Figure 2 shown, a schematic structural diagram of a water supply system 200 according to this embodiment is shown. The water supply system 200 includes a water supply vehicle 201 for supplying water to the water receiving vehicle 202; a water receiving vehicle 202 for receiving the water supply of the water supply vehicle 201 and outputting it; a water supply valve 203 for controlling the water supply flow of the water supply vehicle 201 to the water receiving vehicle 202; and a control device 204 for the water supply system.

[0059] In one embodiment, as Figure 2As shown, the water supply system 200 further includes a liquid level sensor 205 configured to detect the water storage level and fuel level of the water supply vehicle 201 and the water receiving vehicle 202; a flow meter 206 configured to detect the water supply flow rate of the water supply vehicle 201 and the water discharge flow rate of the water receiving vehicle 202; and an environmental sensor 207 configured to detect the environmental parameters at the task site.

[0060] In one embodiment, a processor is provided, configured to execute the control method for the water supply system in any one of the above.

[0061] The water supply system includes at least one water supply vehicle and one water receiving vehicle. A water supply valve and a flow meter are connected between each water receiving vehicle and the water supply vehicle. The water supply vehicle supplies water to the water receiving vehicle through the water supply valve, and the flow meter can record the water supply flow rate of the water supply vehicle for each water receiving vehicle.

[0062] The processor can obtain the water storage level and fuel level in the water supply vehicle. The processor can determine the available water supply duration of the water supply vehicle based on the water storage level and fuel level of the water supply vehicle. When the processor determines that the available water supply duration of the water supply vehicle is greater than the first preset duration set by the processor, the processor can determine that the water supply vehicle has completed the water supply preparation operation for the water receiving vehicle. If the processor determines that the available water supply duration of the water supply vehicle is less than the first preset duration, the processor determines that the water supply vehicle has not completed the water supply preparation operation for the water receiving vehicle, and the water supply vehicle cannot supply water to the water receiving vehicle. After the processor determines that the water supply vehicle has completed the water supply preparation operation for the water receiving vehicle, it will control the water supply vehicle to supply water to the water receiving vehicle, and the water receiving vehicle will perform the water pumping operation, that is, output water to the task point.

[0063] After the water supply vehicle supplies water, it can divert water to supply each water receiving vehicle. The processor can obtain the water supply flow rate of the water supply vehicle and the water discharge flow rate of each water receiving vehicle. After receiving the water provided by the water supply vehicle, the water receiving vehicle will discharge water to work at the task site. The processor determines the total water discharge flow rate based on the obtained water discharge flow rate of each water receiving vehicle and compares the water supply flow rate of the water supply vehicle with the total water discharge flow rate. When the processor determines that the water supply flow rate is less than the total water discharge flow rate, that is, the flow rate of the water supply vehicle is insufficient at this time, the processor needs to reduce the water discharge flow rate of the water receiving vehicle to make the water supply flow rate close to the total water discharge flow rate and achieve flow balance. The processor can reduce the water discharge flow rate of the water receiving vehicle by reducing the engine speed of the water receiving vehicle so that the error between the water supply flow rate and the total water discharge flow rate is within the preset error range.

[0064] In the case where the water supply flow rate is greater than the total water discharge flow rate, that is, when the water supply flow rate of the water supply vehicle is excessive at this time, the processor needs to reduce the water supply flow rate of the water supply vehicle so that the water supply flow rate is close to the total water discharge flow rate and achieve flow balance. The processor can control and reduce the water supply flow rate of the water supply vehicle so that the error value between the water supply flow rate and the total water discharge flow rate is within the preset error range. When the water supply flow rate decreases and the water supply flow rate and the total water discharge flow rate reach flow balance, the water supply flow rate of the water supply vehicle for each water receiving vehicle may not be balanced. At this time, the processor can adjust the valve opening of the water supply valve corresponding to each water receiving vehicle so that the error between the water supply flow rate of the water supply vehicle for each water receiving vehicle and the water discharge flow rate of each water receiving vehicle is within the preset error range.

[0065] The processor can obtain the water storage level in the water supply vehicle. When the processor determines that the water storage level in the water supply vehicle is lower than the preset level value set by the processor, the preset level value can be set according to the liquid level safety value of the water supply vehicle. When the processor determines that the water storage level in the water supply vehicle is lower than the preset level value set by the processor, that is, lower than the liquid level safety value, it indicates that the water storage capacity of the water supply vehicle is insufficient at this time and the water supply vehicle cannot continue to stably supply water to the water receiving vehicle. The processor can control the engine speed of the water supply vehicle to be reduced to the vehicle idle speed of the water supply vehicle to reduce the water supply flow rate of the water supply vehicle. After the water supply vehicle reduces the water supply flow rate, it needs to send an adjustment signal to the water receiving vehicle so that the water receiving vehicle can adjust the water discharge flow rate according to its own water storage level, so that the water receiving vehicle can output depending on its own water storage capacity, so that the water supply vehicle can perform replacement or replenishment work.

[0066] After determining that the water receiving vehicle has received the adjustment notice, the processor can obtain the water storage level of the water receiving vehicle and adjust the engine speed of the water receiving vehicle according to the water storage level in the water receiving vehicle, that is, adjust the water discharge flow rate of the water receiving vehicle. By adjusting the water discharge flow rate of the water receiving vehicle, the water discharge duration when the water receiving vehicle discharges water at a preset speed based on its current water storage level is greater than the second preset duration set by the processor, that is, the water receiving vehicle can stably and reliably output for the second preset duration based on its current water storage level. For example, assuming that the second preset duration set by the processor is 3 minutes, after the water receiving vehicle receives the adjustment notice, the processor can adjust the engine speed of the water receiving vehicle according to the water storage level of the water receiving vehicle, so that the water discharge duration when the water receiving vehicle discharges water at a preset speed is greater than 3 minutes, that is, the water receiving vehicle can stably output for a time greater than 3 minutes.

[0067] When a water receiving vehicle breaks down, the processor can control the valve of the water supply valve corresponding to the malfunctioning water receiving vehicle to be closed and re-determine the total water discharge flow rate of the water receiving vehicle, so as to adjust the water supply vehicle so that the error between the water supply flow rate and the total water discharge flow rate is within the preset error range.

[0068] When the water supply truck supplies water to multiple water receiving trucks, the water supply volume for each water receiving truck can be adjusted by adjusting the valve opening of the water supply valve connected to each water receiving truck. It is ensured that the error between the water supply flow rate of the water supply truck for each water receiving truck and the water outflow flow rate of each water receiving truck is within the preset error range. When the water outlet flow rate of each water receiving vehicle is different, the target water supply flow rate for each water receiving vehicle is also different. The processor can obtain the fuel level value and unit fuel consumption of each water receiving vehicle, determine the working time of each water receiving vehicle according to the fuel level value and unit fuel consumption of each water receiving vehicle, and determine the target water supply flow rate of the water supply vehicle for each water receiving vehicle according to the working time of each water receiving vehicle. If the difference between the working times of any two water receiving vehicles among all the water receiving vehicles is within the preset difference range set by the processor, that is, the working times of all the water receiving vehicles are equivalent, the processor can determine the target water supply flow rate of each water receiving vehicle according to the number of water receiving vehicles and the total water outlet flow rate, and the processor can determine that the target water supply flow rate of each water receiving vehicle is the same. The processor can make the target water supply flow consistent by adjusting the valve opening of the water supply valve. When the processor determines that the difference between the working hours of at least two water receiving vehicles exceeds the preset difference range, that is, not all water receiving vehicles have the same working hours, the processor can determine the flow coefficient of each water receiving vehicle. The processor can determine the flow coefficient of each water receiving vehicle based on the working hours of each water receiving vehicle, thereby determining the target water supply flow corresponding to each water receiving vehicle.

[0069] The processor can also obtain the working parameters of each water receiving vehicle. The working parameters may include the water discharge parameters of the water receiving vehicle and the environmental parameters of the task site where the water receiving vehicle is located. For example, the water discharge parameters of the vehicle may include the water discharge flow rate of the vehicle, the spraying distance of the vehicle, etc. The environmental parameters may include the distance of the vehicle from the center of the fire, the position of the vehicle relative to the center of the fire, the landing point of the vehicle's water spray, etc. The processor can determine the contribution value of each water receiving vehicle to the task required to be performed at the task site based on the above parameters, and determine the flow coefficient of each water receiving vehicle based on the contribution value of each water receiving vehicle, and determine the target water supply flow of each water receiving vehicle based on the flow coefficient of each water receiving vehicle.

[0070] Through the above technical solution, when the water supply truck supplies water to multiple vehicles, the water supply flow and water outlet flow can be adjusted to maximize the tacit cooperation between the vehicles, avoiding uneven distribution of water supply resources and waste of water supply resources. In addition, when the liquid level of the water supply truck is lower than the safe value, the flow of the receiving truck is adjusted to facilitate replacement or rehydration of the water supply truck, thereby improving the rescue efficiency, and the water supply flow for each vehicle can be adjusted according to the contribution value of the receiving truck, so that the contribution to the mission site can be maximized.
