Description

Technical Field

[0001] This utility model relates to the field of fire inspection and alarm technology, and in particular to a campus fire inspection and alarm system. Background Technology

[0002] Fire detection and alarm systems are a crucial component of smart campus security management. Current technologies, mostly based on single sensors or sensor networks, rely solely on individual indicators such as smoke and temperature for fire detection, resulting in high false alarm and false negative rates. Furthermore, existing technologies typically provide only static information and cannot monitor and analyze dynamic changes within the campus in real time.

[0003] Existing technologies, such as the utility model of an automatic fire alarm inspection and detection device (authorization number CN217056937U), not only facilitate angle adjustment of the inspection equipment but also protect the rotating inspection equipment. Furthermore, the movable rubber rod prevents hard impacts, protecting the rubber rod and other components. It also facilitates the installation of the first spring and is easy to manufacture.

[0004] Currently, there is a lack of a fire inspection and alarm system that can move within the campus, raise its shell to avoid obstacles, and smoothly traverse uneven surfaces.

[0005] Therefore, in order to address the above problems, a campus fire inspection and alarm system is proposed. Summary of the Invention

[0025] like Figures 1 to 5 As shown, a campus fire patrol and alarm system includes: a hollow vehicle body 6, which houses an alarm component and an obstacle avoidance component, and is mobile via four sets of wheel assemblies; the alarm component includes a controller 5, symmetrical cameras 3, and smoke sensors 1, wherein the smoke sensors 1 detect smoke, the cameras 3 monitor the surrounding environment in real time, and the controller 5 receives sensor signals and sends the signals and image information to a host computer; the smoke sensors 1 are mounted on the upper side of a mounting base 2, the symmetrical cameras 3 are mounted on the front side of the mounting base 2, the upper end of a connecting conduit 4 is connected to the mounting base 2, the lower end of the conduit 4 is connected to the vehicle body 6, the controller 5 is connected to the vehicle body 6, and the cameras 3 and the smoke sensors 1 are electrically connected to the controller 5; the obstacle avoidance component is connected to the vehicle body 6 and helps the system avoid obstacles during movement; the four sets of wheel assemblies are respectively connected to the obstacle avoidance component, providing the system with mobility and enabling the system to autonomously patrol the campus.

[0026] The controller 5 is wirelessly connected to a host computer, which includes, but is not limited to, computers, monitors, PCs, and mobile phones.

[0027] The obstacle avoidance assembly includes an electric push rod 8 and a telescopic rod 11 for adjusting the height of the vehicle body 6. The fixed ends of the electric push rod 8 and the telescopic rod 11 are connected to the vehicle body 6. The electric push rod 8 is electrically connected to the controller 5. The push rod of the electric push rod 8 and the free ends of the telescopic rod 11 are respectively connected to the mounting crossbar 7. The wheel assembly includes a wheel seat 17, a wheel 18, and a servo reduction motor 16. The output shaft of the servo reduction motor 16 is connected to the axle of the wheel 18. The servo reduction motor 16 drives the wheel 18 to rotate, realizing the movement function of the system.

[0028] The servo geared motor 16 includes a servo motor and a reducer. The servo motor is connected to the reducer, the output shaft of the servo motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the axle of the wheel 18.

[0029] The servo motor is model STM2851B-485, equipped with DMA860H digital two-phase stepper driver, and a wireless module (such as Wi-Fi or Bluetooth module) is connected to the control signal input port of DMA860H to receive control signals from controller 5 wirelessly.

[0030] In Embodiments 1 and 2, the reducer is connected to the wheel seat 17; in Embodiment 3, the reducer is connected to the frame 25.

[0031] Example 1: As Figure 1As shown, the two ends of the mounting crossbar 7 are respectively connected to U-frames 9. The vertical rod of each U-frame 9 passes through the bottom plate of the vehicle body 6. The vertical rod of each U-frame 9 is connected to the corresponding wheel seat 17. The wheel seat 17 is connected to the axle of the wheel 18 by a bearing. The wheel seat 17 is connected to the servo reduction motor 16. When the electric push rod 8 extends, the wheel 18 moves downward relative to the vehicle body 6.

[0032] The workflow of this embodiment is as follows:

[0033] When an obstacle is observed through camera 3, the four servo reduction motors 16 can be controlled to rotate at different speeds to achieve turning and obstacle crossing. The electric push rod 8 can also be extended. Since the wheel 18 is in contact with the ground, the electric push rod 8 moves upward, which in turn moves the car body 6 upward.

[0034] Example 2: Figure 2 As shown, the top plate of the vehicle body 6 is connected to two sets of symmetrical diagonal rods 10. The vehicle body 6 is provided with symmetrical clearance grooves. Each diagonal rod 10 is respectively set in a diagonal tube 14, and each diagonal tube 14 is respectively set in a corresponding clearance groove. Each diagonal tube 14 is respectively connected to a circular block 13. The two ends of the mounting crossbar 7 are respectively connected to a sliding groove 12. Each circular block 13 is respectively set in a corresponding sliding groove 12. Each diagonal tube 14 is respectively connected to a servo motor 15. The output shaft of each servo motor 15 is respectively connected to a corresponding wheel seat 17. The wheel seat 17 is connected to the axle of the wheel 18 by a bearing. The wheel seat 17 is connected to the servo reduction motor 16. When the electric push rod 8 extends, the wheel 18 moves downward and outward relative to the vehicle body 6. By controlling the rotation of the servo motor 15, the wheel 18 faces outward, which facilitates the movement of the wheel 18 when the electric push rod 8 extends. The servo motor 15 is electrically connected to the controller 5.

[0035] The servo motor 15 is model TD-8135MG.

[0036] The workflow of this embodiment is as follows:

[0037] When an obstacle is observed through camera 3, before the electric push rod 8 extends, the servo motor 15 is rotated 90 degrees, causing the servo motor 15 to drive the wheel seat 17, wheel 18 and servo reduction motor 16 to swing, so that the wheel 18 faces outward. When the electric push rod 8 extends, the car body 6 drives the inclined rod 10 to move upward, the inclined rod 10 drives the inclined tube 14 to move outward, and the inclined tube 14 drives the servo motor 15, wheel seat 17, wheel 18 and servo reduction motor 16 to move outward.

[0038] Example 3: Figure 3-4As shown, this embodiment is a further elaboration based on Embodiment 1 or 2. The wheel seat 17 is provided with symmetrical vertical grooves 21, and spring cylinders 22 are respectively provided in the symmetrical vertical grooves 21. Each spring cylinder 22 is connected to the wheel seat 17. Each spring cylinder 22 is provided with the upper end of a spring 26 and a spring rod 24. Each spring rod 24 is connected to one end of the corresponding spring 26, and each spring cylinder 22 is connected to the other end of the corresponding spring 26. Each spring rod 24 is connected to a square seat 27, each square seat 27 is connected to a round tube 28, and each round tube 28 is connected to a frame 25. The wheel axle of the wheel 18 passes through the symmetrical square seats 27 and the symmetrical round tubes 28. The wheel axle bearing of the wheel 18 is connected to the frame 25, and the frame 25 is connected to the servo reduction motor 16. The spring cylinders 22, springs 26, and spring rods 24 achieve shock absorption, ensuring the stability of the system when driving on uneven roads.

[0039] The workflow of this embodiment is as follows:

[0040] When the system is traveling on the road, the spring 26 is compressed under the gravity of the relevant components.

[0041] When encountering a pit or a protrusion, taking a protrusion as an example, the wheel 18 moves upward, and the wheel 18 drives the square seat 27, the round tube 28 and the frame 25 to move downward. The square seat 27 drives the spring rod 24 to move along the spring cylinder 22, and the spring rod 24 compresses the spring 26.

[0042] Example 4: Figure 3-4 As shown, this embodiment is a further elaboration based on embodiment three. The wheel seat 17 is connected to the T-shaft 19, and the T-shaft 19 is rotatably connected to the square seat of the symmetrical guide cylinder 20. The symmetrical guide cylinder 20 is provided with guide rods 23 respectively, and the end rings of the symmetrical guide rods 23 are rotatably connected to the corresponding round tubes 28, thereby increasing the stability of the system.

[0043] The workflow of this embodiment is as follows:

[0044] When the circular tube 28 moves along the height direction, it drives the guide rod 23 to swing and move along the guide cylinder 20 at the same time. The guide rod 23 drives the guide cylinder 20 to swing.
