Description

Technical Field

[0001] This invention relates to the field of personnel operation training record evaluation for handheld fire hoses, specifically an automatic fire hose identification device. Background Technology

[0002] In firefighting, water hoses are among the most commonly used tools. Traditionally, firefighters manually control parameters such as the direction, flow rate, and spray height of the water. If firefighters are not skilled enough in adjusting the spray direction, water volume, and angle, it can significantly impact the effectiveness of rescue operations. Traditional firefighting equipment training primarily relies on observation and guidance from supervisors. However, due to the complexity and diversity of disaster environments and the size of the training group, supervisors often cannot promptly and accurately obtain and guide trainees on proper water hose operation methods. Summary of the Invention

[0003] The purpose of this invention is to address the existing problems of automatically identifying the water type, flow rate, and attitude of fire hoses by proposing an automatic identification device for controlling the water type, flow rate, and attitude of fire hoses.

[0004] An automatic identification device for fire hose nozzles includes a nozzle adapter mounted on the nozzle, an assembled circular main unit, a water flow regulating valve, a handle, and a push-rod switch. The nozzle adapter is a detachable circular ring with several magnets placed on it. The assembled circular main unit is installed between the nozzle adapter and the water flow regulating valve. The assembled circular main unit is a non-magnetic ring. Several magnetic induction angle sensors are evenly distributed on the side facing the nozzle adapter, corresponding to the magnets on the nozzle adapter. Magnetic induction sensors are installed on the side facing the water flow regulating valve. Regulating valve adapters are installed on the water flow regulating valve according to their positions, and the regulating valve adapters are equipped with magnets corresponding to the magnetic induction sensors. An angle sensor is installed on the push-rod switch to measure the rotation angle of the push-rod switch during rotation. At both ends of the handle are posture sensors, and the handle is connected between the water flow regulating valve and the push-rod switch.

[0005] Furthermore, it also includes a microcontroller connected to an angle sensor, a magnetic induction sensor, a magnetic induction angle sensor, and an attitude sensor. The microcontroller is used to calculate the water flow rate of the water gun at this time based on the pulse signal output by the magnetic induction sensor, to output the water pattern at this time based on the Gray code output by the magnetic induction angle sensor, to determine the water flow rate of the water gun at this time based on the rotation angle measured by the angle sensor, and to obtain the trainee's coordinate orientation and operating actions based on the signal measured by the attitude sensor.

[0006] Furthermore, the nozzle adapter is fixed to the nozzle using double-sided tape or clips.

[0007] Furthermore, when the water flow regulating valve is adjusted, the magnet corresponding to the gear on the regulating valve adapter also rotates synchronously. The magnet of the regulating valve adapter meets the magnetic induction sensor on the assembled circular host and outputs the pulse signal.

[0008] Furthermore, the attitude sensor includes a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass.

[0009] Furthermore, eight magnetic induction angle sensors are evenly distributed at 22.5-degree intervals on one side of the nozzle opening. When the nozzle rotates, the eight evenly distributed magnets on the nozzle adapter meet the eight magnetic induction angle sensors in sequence and output signals in the form of Gray code. The specific value of the Gray code corresponds to its water pattern.

[0010] The technical effects achieved by this invention are as follows:

[0011] This invention is compatible with existing internationally accepted water gun specifications. It applies technologies such as magnetoresistive sensing, MEMS micro-motion attitude recognition, microcontroller and coding, and wireless communication to complete the digital transformation of traditional water guns through simple installation without changing the operation method and core structure of the fire hose. At the same time, it can also create parameter scripts for water gun operation to standardize the water gun operation parameters, which facilitates the expansion of applications for different models of water guns, different groups of people, and different scenarios.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 and Figure 2 As a specific embodiment of the present invention, an automatic fire hose identification device is disclosed, which can identify the water type, water volume, posture and other controls of the fire hose. It can be used in the field of personnel operation training record evaluation of handheld fire hoses. The automatic fire hose identification device includes a nozzle adapter 001, an assembled circular main unit 002, a handle 003, a push rod switch 004, and a water flow regulating valve 006.

[0025] Please refer to the reference. Figure 3 This is a schematic diagram of the nozzle adapter 001 on the nozzle of a water gun. The nozzle adapter 001 is installed on the nozzle 011. The nozzle adapter 001 is a detachable ring that can be fixed using common methods such as double-sided tape or clips. The nozzle adapter 001 can rotate synchronously with the nozzle 011. Several magnets 010 are placed on the nozzle adapter 001 without causing mechanical interference to the rotation of the nozzle 011.

[0026] like Figure 4The diagram shows the structure of the water flow regulating valve 006 and the regulating valve adapter 007. The regulating valve adapter 007 containing a magnet is installed on the water flow regulating valve 006 according to the gear position. The regulating valve adapter 007 engages with the water flow regulating valve 006. The regulating valve adapter 007 containing the magnet rotates synchronously with the water flow regulating valve 006. When the water flow regulating valve 006 is adjusted, the magnet on the regulating valve adapter 007 corresponding to the gear position also rotates synchronously.

[0027] like Figure 5 The diagram shows the installation position of the assembled circular ring main unit 002. The assembled circular ring main unit 002 is a non-magnetic ring, assembled and fixed between the nozzle orifice of the nozzle 011 and the water flow regulating valve 006. Eight magnetic induction angle sensors 009 are evenly distributed at 22.5-degree intervals on one side towards the nozzle orifice. The vertical starting position of the magnetic induction angle sensors 009 coincides with the vertical starting position of the magnet rotating on the nozzle adapter 001. When the nozzle 011 rotates, the magnet on the nozzle adapter 001 rotates along with it, encountering the magnetic induction angle sensors 009 on the assembled circular ring main unit 002. The magnetic induction angle sensors 009 output pulses. Because the magnetic induction angle sensors 009 are arranged at 22.5-degree intervals, each pulse output indicates that the nozzle orifice has rotated 22.5 degrees. Since the rotation angle of the nozzle orifice is synchronized with the angle of the water flow, a larger angle changes the water pattern, such as... Figure 9 As shown, eight evenly distributed magnets sequentially encounter eight magnetic induction angle sensors 009, outputting signals in the form of Gray code. The specific value of the Gray code corresponds to the water pattern. The magnets on the regulating valve adapter 007 of the water flow regulating valve 006 are distributed according to the water flow level. During the rotation of the water flow regulating valve 006, the magnets encounter the magnetic induction sensor 008 on the assembled circular main unit 002 (e.g., ...). Figure 10 As shown in the figure, the output pulse can be used to calculate the water flow rate of the water gun at this time.

[0028] like Figure 6 The diagram shows a push-rod switch 004. An angle sensor 005 is installed on the push-rod switch 004. During the rotation of the push-rod switch 004, the angle sensor 005 can measure the rotation angle of the push-rod switch 004. During the rotation of the push-rod switch 004, the water flow rate of the water gun changes. The rotation angle measured by the angle sensor 005 can determine the water flow rate of the water gun at this time.

[0029] like Figure 7The diagram shows the structure of handle 003, which includes a microcontroller, a wireless transceiver module 014 connected to the microcontroller, a battery, a switch indicator light 013, and a charging port 015. Attitude sensors 012 are installed at both ends of handle 003, bridging the water flow regulating valve 006 and the push-rod switch 004. The attitude sensor 012 is a high-performance three-dimensional motion attitude measurement system based on MEMS technology, including a three-axis gyroscope, a three-axis accelerometer, and a three-axis electronic compass, which can obtain the trainee's current coordinates and operational actions. The wireless transceiver module 014 can wirelessly transmit the collected signal.

[0030] like Figure 8 The diagram shows the process of modifying a water gun. The microcontroller is connected to angle sensor 005, magnetic induction sensor array (magnetic induction sensor 008, magnetic induction angle sensor 009), and attitude sensor 012. The microcontroller is used to calculate the water flow rate of the water gun based on the pulse signal output by magnetic induction sensor 008, to output the water pattern based on the Gray code output by magnetic induction angle sensor 009, to determine the water flow rate of the water gun based on the rotation angle measured by angle sensor 005, and to obtain the trainer's coordinates and operating actions based on the signal measured by attitude sensor 012.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
