[0002] With the continuous acceleration of industrialization, informatization and urbanization, various large-scale buildings such as complex commercial buildings and exhibition buildings continue to emerge. Once a fire occurs, the burning area of ​​such large buildings is large, the intensity is high, the firefighting time is long, and the social impact is great, which increases the demand for fire-fighting facilities, such as fire trucks. During the use of the foam fire extinguishing system of the fire truck, due to time constraints and high pressure, users are prone to some misoperation during use, resulting in abnormal damage to the equipment. For example, when exhausting, the exhaust time is too long, or the water injection valve of the pump to the tank is mistakenly opened during the foaming process, causing foam to flow into the water tank, polluting the water in the water tank, thereby affecting the control of the fire and posing a hidden danger of failure.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the embodiments of the present invention is not limited to the specific embodiments disclosed below.

[0031] Refer to the following Figures 1 to 7 Some embodiments according to the invention are described.

[0032] like Figures 1 to 5 As shown, an anti-misoperation system 54 according to an embodiment of the present invention comprises: mutually connected foam devices (2, 5, 19) and a bubble outlet pipe 131, the bubble outlet pipe 131 is used to produce foam. Interconnected water supply devices (1, 18) and a first water outlet pipe 99, the first water outlet pipe 99 is used to produce water. The first water outlet pipe 99 is also connected to the foam device (2, 5, 19), and the first water outlet pipe 99 is also used to produce foam. A control valve group (8, 9, 11, 12, 13, 14) is used to control the bubble outlet pipe 131 to produce bubbles, and / or to control the first water outlet pipe 99 to produce water or foam. A first controller 20 is used to receive an operation instruction and control the action of the control valve group (8, 9, 11, 12, 13, 14) according to the operation instruction. The detection device (210, 211, 212, 213, 214, 215) is connected to the first controller 20, wherein the detection device (210, 211, 212, 213, 214, 215) is used to detect the execution result of the operation instruction, and the first controller 20 is also used to determine whether there is an erroneous operation based on the execution result, and control the control valve group (8, 9, 11, 12, 13, 14) to terminate the erroneous operation.

[0033] In this embodiment, the detection device (210, 211, 212, 213, 214, 215) is used to detect the execution result of the operation instruction, and the first controller 20 determines whether there is an erroneous operation based on the execution result. By controlling the control valve group (8, 9, 11, 12, 13, 14) to terminate the erroneous operation, it is helpful to timely discover the erroneous operation, and terminate the erroneous operation before the erroneous operation causes a large loss, or before the loss or safety accident occurs. By terminating the erroneous operation, the failure of the equipment can be reduced, the pollution of the water supply device (1, 18) by the foam can be reduced, and the stability and reliability of the equipment operation can be improved.

[0034] Specifically, by providing a foam device (2, 5, 19) and a water supply device (1, 18), it is convenient to use foam or water to extinguish fire according to different fire situations, so as to improve the speed of fire extinguishing and the safety and effectiveness of fire extinguishing. The first water outlet pipe 99 is connected to the water supply device (1, 18) and connected to the foam device (2, 5, 19), so that the first water outlet pipe 99 can be used to discharge foam or water, so that it is convenient to connect a water monitor 4 to the first water outlet pipe 99 to transport foam or water to a longer distance, thereby improving the fire extinguishing distance. The setting of the control valve group (8, 9, 11, 12, 13, 14) is convenient for controlling the opening and closing of the bubble outlet pipe 131 and the first water outlet pipe 99, reducing the mutual interference between the bubble outlet pipe 131 and the first water outlet pipe 99, and improving the accuracy of the bubble outlet operation, the water outlet operation, and the bubble outlet or water outlet operation from the first water outlet pipe 99. By setting up a detection device (210, 211, 212, 213, 214, 215) to detect the execution result of the operation instruction, that is, to detect factors such as water output, foam output, water output pressure, foam output pressure, flow rate, etc., the first controller 20 can judge whether the execution result of the actual operation is the same as the execution result corresponding to the operation instruction through these factors, so as to judge whether there is an erroneous operation. When an erroneous operation occurs, the first controller 20 controls the control valve group (8, 9, 11, 12, 13, 14) to take corresponding actions to terminate the erroneous operation in time, thereby reducing losses, reducing equipment failure rate and pollution to water sources, improving the stability and reliability of equipment operation, and reducing potential failure hazards.

[0035] like Figure 1 and Figure 2As shown, in the above embodiment, the water supply device (1, 18) includes: a water pump 1 and a water tank 18. The inlet of the water pump 1 is connected to the water tank 18, and the outlet of the water pump 1 is connected to the water tank 18 through the first pipeline 31. The outlet of the water pump 1 is connected to the foam device (2, 5, 19) through the second pipeline 32. The outlet of the water pump 1 is connected to the first water outlet pipe 99 through the third pipeline 33. The outlet of the foam device (2, 5, 19) is connected to the bubble outlet pipe 131 through the fourth pipeline 34. The outlet of the foam device (2, 5, 19) is connected to the first water outlet pipe 99 through the fifth pipeline 35. The control valve group (8, 9, 11, 12, 13, 14) includes: a water injection valve 8, which is arranged on the first pipeline 31 to control the on-off of the first pipeline 31. The first water outlet valve 9, which is arranged on the third pipeline 33 to control the on-off of the third pipeline 33. The first bubble valve 13 is arranged on the fourth pipeline 34 to control the on-off of the fourth pipeline 34. The second bubble valve 14 is arranged on the fifth pipeline 35 to control the on-off of the fifth pipeline 35. The detection device (210, 211, 212, 213, 214, 215) includes: a water level sensor 211 and a foam level sensor 212. The water level sensor 211 is electrically connected to the first controller 20, and the water level sensor 211 is used to obtain the water level in the water tank 18 and generate water level information. The foam level sensor 212 is electrically connected to the first controller 20, and the foam level sensor 212 is used to obtain the foam level in the foam device (2, 5, 19) and generate foam level information. The first controller 20 is specifically used to receive an operation instruction for the bubble tube 131 to produce foam, and open the first bubble valve 13 according to the operation instruction. The first controller 20 is also used to determine whether one or more of the water injection valve 8, the first water outlet valve 9, and the second bubble outlet valve 14 are opened by mistake according to the received water level information and foam liquid level information, and terminate the mistaken operation.

[0036] In this embodiment, when the first bubble outlet valve 13 is opened, the foam can be discharged from the bubble outlet pipe 131, and the foam liquid level will change. At the same time, the outlet of the water pump 1 is connected to the foam device (2, 5, 19) through the second pipeline 32. No control valve is set on the second pipeline 32. Therefore, under normal circumstances, after the first bubble outlet valve 13 is opened, and other control valves are not opened, the water in the water supply device (1, 18) can enter the foam device (2, 5, 19) through the outlet of the water pump 1 through the second pipeline 32 and be discharged with the foam device (2, 5, 19). If an erroneous operation occurs, such as Figure 1As shown, for example, if the water injection valve 8, the first water outlet valve 9, and the second bubble outlet valve 14 are all opened by mistake, the foam of the foam device (2, 5, 19) may flow into the water tank 18 through the second bubble outlet valve 14, the first water outlet valve 9, and the water injection valve 8, causing the water in the water tank 18 to be polluted, and also reducing the amount of foam discharged from the bubble outlet pipe 131. At this time, the water level in the water tank 18 may increase instead of decrease, and the foam liquid level in the foam device (2, 5, 19) may drop significantly compared to when only the first bubble outlet valve 13 is opened. Therefore, it can be judged from the water level information and the foam liquid level information that a misoperation has occurred. Similarly, if only the second bubble outlet valve 14 is opened by mistake, part of the foam may be discharged from the first water outlet pipe 99 through the second bubble outlet valve 14, causing the foam liquid level to drop significantly, causing a large change in the foam liquid level information, thereby judging that a misoperation has occurred. If at least one of the first water outlet valve 9 and the water injection valve 8 is opened by mistake, the water at the outlet of the water pump 1 will not only flow to the second pipeline 32, but also may flow to the first pipeline 31 and the third pipeline 33, resulting in a decrease in the outlet pressure of the water pump 1, reducing the flow rate of the second pipeline 32 or even completely stopping the flow from the second pipeline 32, thereby reducing the water entering the foam device (2, 5, 19) and reducing the foaming effect. Then, it is judged whether there is a wrong operation through the change of the foam liquid level and the change of the water level information, and the wrong operation is corrected in time, thereby reducing the phenomenon that the water in the water tank 18 is contaminated by foam.

[0037] It can be understood that the water injection valve 8, the second bubble valve 14, and the first water outlet valve 9 are all connected to the first controller 20. In this way, the water injection valve 8, the second bubble valve 14, and the first water outlet valve 9 can be directly closed by the first controller 20, thereby improving work efficiency and ensuring that the water injection valve 8 or the second bubble valve 14, and the first water outlet valve 9 are closed as soon as they are opened by mistake.

[0038] In addition, it should be noted that the arrangement of the fifth pipeline 35 and the second bubble valve 14 can achieve the purpose of both water and foam being discharged from the first water outlet pipe 99. That is, when the second bubble valve 14 is closed, the first water outlet valve 14 is opened, and only water is discharged from the first water outlet pipe 99. When the second bubble valve 14 is opened and the first water outlet pipe 99 is closed, the first water outlet pipe 99 can discharge foam.

[0039] In some embodiments, the first water outlet pipe 99 can be used to connect to the water monitor 4 so as to spray out foam or water and increase the discharge distance, which is beneficial for long-distance fire fighting.

[0040] In the above embodiment, if Figure 3 and Figure 4As shown, the foam device (2, 5, 19) includes: a foam tank 19, a foam pump 2 and a foam mixer 5. The foam tank 19 is used to store foam. The inlet of the foam pump 2 is connected to the foam tank 19 through the sixth pipeline 36. The first inlet of the foam mixer 5 is connected to the outlet of the foam pump 2 through the seventh pipeline 37, and the second inlet of the foam mixer 5 is connected to the outlet of the water pump 1 through the second pipeline 32. The outlet of the water pump 1 is also connected to the inlet of the foam pump 2 through the eighth pipeline 38, and the eighth pipeline 38 is used to supply water to flush the foam pump 2 and the foam mixer 5. The control valve group (8, 9, 11, 12, 13, 14) also includes: a liquid supply valve 11 and a flushing valve 12. The liquid supply valve 11 is arranged on the sixth pipeline 36 to control the opening and closing of the sixth pipeline 36. The flushing valve 12 is arranged on the eighth pipeline 38 to control the opening and closing of the eighth pipeline 38. The first controller 20 is also used to determine whether the flushing valve 12 is opened by mistake according to the received water level information and foam level information after opening the first bubble valve 13, and terminate the mistaken operation. The first controller 20 is also connected to the water pump 1, and the first controller 20 is also used to control the water pump 1 to reduce the speed according to the flushing instruction.

[0041] In this embodiment, by providing the flushing valve 12 and the eighth pipeline 38, it is convenient to open the flushing valve 12 to allow water to flow through the eighth pipeline 38 after the foaming work of the device is completed, so as to flush the foam pump 2 and the foam mixer 5, reduce the foam residue in the foam pump 2 and the foam mixer 5, thereby reducing the erosion of these devices and improving the service life of the device. Furthermore, after opening the first bubble valve 13, if the flushing valve 12 is opened due to an erroneous operation, the water of the water pump 1 will not only flow from the second pipeline 32 to the foam mixer 5, but also flow to the foam pump 2 through the eighth pipeline 38. On the one hand, the amount of water flowing through the second pipeline 32 will be reduced or even eliminated due to the diversion, and the pumping kinetic energy of the foam pump 2 will intensify the water flow to the eighth pipeline 38, greatly reducing the amount of water in the second pipeline 32. On the other hand, the outlet of the water pump 1 is connected to the inlet of the foam pump 2 through the eighth pipe 38, and the foam tank 19 is connected to the inlet of the foam pump 2 through the sixth pipe 36. Due to the high water pressure, the water will flow back to the sixth pipe 36 through the eighth pipe 38, causing the outlet of the foam tank 19 to be blocked and the foam pump 2 cannot extract the foam, resulting in a foam failure. Correspondingly, the foam liquid level may not change, while the water level drops significantly. Therefore, it is possible to determine whether the flushing valve 12 is opened by mistake based on the foam liquid level information and the water level information, and terminate the mistaken operation in time, that is, close the flushing valve 12.

[0042] It can be understood that the control valve group (8, 9, 11, 12, 13, 14) includes the flushing valve 12, and the first controller 20 can close the flushing valve 12 by controlling the control valve group (8, 9, 11, 12, 13, 14).

[0043] The first controller 20 is also connected to the water pump 1, and upon receiving the flushing instruction, sends a speed reduction instruction to the water pump 1 to reduce the speed, which is beneficial to reducing the water pressure, reducing the impact on the foam pump 2 during flushing, and extending the service life of the foam pump 2. By providing the speed sensor 215, it is beneficial to determine whether the speed reduction instruction is accurately executed, thereby reducing the situation where the water pump 1 is flushed before the speed is reduced.

[0044] It can be understood that compared with water extinguishing, the water pressure required for flushing foam is smaller. Therefore, when flushing foam, the rotation speed of the water pump 1 needs to be reduced before the flushing valve 12 can be opened to facilitate water to flow from the water pump 1 through the eighth pipeline 38 to the foam pump 2 and the foam mixer 5 to flush the foam.

[0045] It should also be pointed out that by providing a foam tank 19, it is convenient to store foam so that the fire truck 50 can use foam to extinguish fires in places where there is no foam source. By providing a liquid supply valve 11, it is convenient to disconnect the sixth pipeline 36 to prevent foam from flowing to the pipeline subsystem and corroding the pipeline. By providing a foam pump 2, it is convenient to extract foam from the foam tank 19. By providing a foam mixer 5, it is convenient to provide a special container to mix foam and water to form a mixed liquid, thereby reducing corrosion to other pipelines. The provision of the second pipeline 32 facilitates water to flow into the foam mixer 5 and mix with the foam. By providing a flushing pipeline and connecting the flushing pipeline to the inlet of the foam pump 2, it is convenient to flush the foam pump 2 and the foam mixer 5, reduce the foam residue in the foam pump 2 and the foam mixer 5, and extend the service life of the equipment. Through the setting of the speed sensor 215, in addition to detecting the speed of the water pump 1 to avoid accidentally opening the flush valve 12, the speed of the water pump 1 can also be controlled more accurately to accurately control the water pressure, so that the water pumping height can be guaranteed when pumping water to a high place, and when pumping water to a low place, the speed of the water pump 1 can be reduced to reduce energy consumption.

[0046] In the above embodiment, the anti-misoperation system 54 also includes: an air compressor 3, connected to the foam device (2, 5, 19), and the air compressor 3 is used to provide compressed air to the foam device (2, 5, 19). The detection device (210, 211, 212, 213, 214, 215) also includes a temperature sensor 210 and / or a flow sensor 214 and / or a pressure sensor 213. The temperature sensor 210 is connected to the air compressor 3, and the temperature sensor 210 is used to obtain the temperature of the air compressor 3 and generate temperature information. The flow sensor 214 is provided on the water pump 1, and the flow sensor 214 is used to obtain the flow of the water pump 1 and generate flow information. The pressure sensor 213 is provided on the water pump 1, and the pressure sensor 213 is used to obtain the water outlet pressure of the water pump 1 and generate pressure information. The first controller 20 is also specifically used to receive an operation instruction for the first water outlet pipe 99 to discharge water, and open the first water outlet valve 9 according to the operation instruction. The first controller 20 also determines whether one or more of the water injection valve 8, the flushing valve 12, the first bubble valve 13, and the second bubble valve 14 are opened by mistake based on the received flow information and / or pressure information and / or temperature information and / or water level information and / or foam liquid level information, and terminates the mistaken operation.

[0047] In this embodiment, when the first water outlet pipe 99 is discharging water, the foam device (2, 5, 19) does not work, so no water will flow to the second pipeline 32. If any one of the first bubble valve 13, the second bubble valve 14, and the flushing valve 12 is opened by mistake, the flow rate of the water supply device (1, 18) will increase and the water level will drop significantly. Therefore, it can be judged from the flow information, pressure information, and water level information whether there is a misoperation that causes the first bubble valve 13, the second bubble valve 14, and the flushing valve 12 to be opened by mistake when the first water outlet pipe 99 is discharging water. Similarly, if the water injection valve 8 is opened by mistake, the water at the outlet of the water pump 1 directly returns to the water tank 18 through the water injection valve 8, and the water level may not change, so it can be judged that a misoperation has occurred. In addition, under normal circumstances, water is discharged from the first water outlet pipe 99 and foam is not needed, so the air compressor 3 will not work and its temperature is low. If the temperature information fed back by the temperature sensor 210 reflects a higher temperature, it means that the air compressor 3 is working. Therefore, it is very likely that the first bubble valve 13 and the second bubble valve 14 are opened by mistake to produce foam. Therefore, it can be judged based on the temperature information that one of the first bubble valve 13 and the second bubble valve 14 is opened by mistake.

[0048] By terminating the misoperation through the first controller 20, the misoperation can be terminated quickly without waiting for the user to terminate it manually, which is conducive to improving work efficiency and reducing equipment failures and safety accidents caused by misoperation. Especially in fire fighting, it is conducive to ensuring the use of the correct fire extinguishing medium, ensuring the fire extinguishing effect, and reducing the loss of life and property.

Alternatively, the alarm device 40 is a combination of a display device and an audio device, and can send out visual information and audio information at the same time.

[0051] In this embodiment, by setting up the alarm device 40, it is convenient for the first controller 20 to control the alarm device 40 to issue a warning message, promptly reminding the user to make adjustments to avoid equipment failure, or to terminate the fire extinguishing operation in time to avoid the use of the wrong medium causing the fire to become larger, thereby effectively reducing misoperation and improving the convenience of equipment use.

[0075] The operating principle and operation method of the anti-misoperation system 54 of this specific embodiment are as follows:

[0076] 1. When a fire occurs, complete the preparatory work in a race against time to extinguish the fire quickly.

[0077] 2. On the first operation terminal 206 connected to the first controller 20, open the exhaust device 56, such as a vacuum pump, to exhaust excess air from the pipeline. When the operation reaches a preset time, such as one minute, the processor 204 in the first controller 20 analyzes and compares the program in the memory 202 and automatically cuts off the power to prevent the vacuum pump from overheating and damaging the equipment when the operation time exceeds the preset time.

[0078] 3. During the foaming process, on the first operation terminal 206 connected to the first controller 20, it is determined whether the pump is opened by mistake to return water to the tank. The information accurately fed back by the water level sensor 211 and the foam level sensor 212 is sent to the processor 204, and the analysis and judgment are performed according to the program of the memory 202. If the operation is normal, the operation instruction is allowed to be implemented. If it is an erroneous operation, an alarm is sounded on the first display 200 connected to the first controller 20, and corresponding warning text or pattern is prompted to stop the erroneous opening of the pump to return water to the tank, for example, the water injection valve 8 is closed.

[0079] 4. When the water-blasting operation is performed on the first operation terminal 206 connected to the first controller 20, it is determined whether the foam-blasting operation instruction is opened by mistake. When the processor 204 in the first controller 20 only receives the information of pressure and flow feedback, the processor 204 analyzes and determines that the operation is normal according to the program of the memory 202, and allows the operation instruction to be implemented. When the processor 204 in the first controller 20 not only receives the information of pressure and flow feedback, but also receives the information of the temperature sensor 210 of the operation of the air compressor 3, at this time, the system determines that the foam-blasting operation instruction has been opened, and then an alarm is issued on the first display 200 connected to the first controller 20, and a corresponding warning text or pattern is prompted to stop the foam-blasting operation instruction from being opened by mistake, for example, the first bubble valve 13 is closed.

[0080] 5. When performing a foam flushing operation on the first operating terminal 206 connected to the first controller 20, determine whether to reduce the speed of the water pump according to the operating instruction. When the processor 204 in the first controller 20 receives the speed information fed back by the speed sensor 215, the processor 204 analyzes and determines according to the program in the memory 202. If the speed information meets the set value, the default operation is normal and the operating instruction is allowed to be implemented. When the processor 204 in the first controller 20 receives the speed information fed back by the speed sensor 215, the processor 204 analyzes and determines according to the program in the memory 202. If the speed information exceeds the set value, the default operation is abnormal and the operating instruction is not allowed to be implemented. At the same time, the display on the first controller 20 alarms and prompts the corresponding warning text or pattern.

[0081] 6. The above operations 2, 3, 4, and 5 can realize data communication with the second operation terminal 221 and the second display 220 connected to the cab controller 22, can be displayed synchronously through the second display 220, and can also be operated synchronously through the second operation terminal 221.
