Description

Technical Field

[0001] This utility model relates to the field of camera technology, and more specifically, to a surveillance camera for subway transportation management. Background Technology

[0002] Surveillance cameras are semiconductor imaging devices with advantages such as high sensitivity, resistance to strong light, low distortion, long lifespan, and vibration resistance. They are used in subway stations to monitor and record the subway station in order to collect data such as passenger flow.

[0003] In the prior art, for example, Chinese Patent Publication No. CN204733239U discloses another type of easily detachable and retractable security monitoring camera, including a camera body, a top cover, a first connecting arm, a second connecting arm, and a mounting base fixed to the wall by screws. The top cover covers the top of the camera body. One end of the first connecting arm is hinged to the bottom of the camera body via a vertical hinge axis, and the other end of the first connecting arm is hinged to one end of the second connecting arm via a horizontal hinge axis. A first magnet is fixed to the other end of the second connecting arm. A blind hole for inserting the second connecting arm is provided on the front of the mounting base. A second magnet is fixed to the bottom of the blind hole. The first magnet and the second magnet can attract each other. The second connecting arm is a telescopic rod, which is composed of multiple sections of tubular body that are movably sleeved. It is relatively convenient to install and disassemble, and can move a large distance.

[0004] However, existing cameras either have non-adjustable angles or require manual adjustment. Since cameras are installed at high locations, manual adjustment is very inconvenient and cannot achieve all-round real-time monitoring. Multiple cameras are needed to achieve all-round monitoring, which not only increases monitoring costs but also increases the time required to deploy the cameras. In view of this, we propose a monitoring camera for subway transportation management. Utility Model Content

[0005] The purpose of this utility model is to provide a surveillance camera for subway transportation management to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a surveillance camera for subway transportation management, including a mobile platform. Several fixed blocks are fixedly connected to the top of the mobile platform, and several sliding rods are fixedly connected to the top of the mobile platform. A sliding base is movably connected to the surface of each sliding rod. A spiral hole is formed in the inner cavity of the sliding base, and a threaded rod is rotatably connected to the inner cavity of the spiral hole. Several sliding holes are formed on both sides of the spiral hole, and several pulleys are provided in the inner cavity of each sliding hole. The two ends of the threaded rod are rotatably connected to the fixed blocks, and the sliding rods are movably connected to the sliding holes. The inner cavity of the sliding hole and the surface of the sliding rod are in close contact and are both inverted trapezoidal in shape.

[0007] As a further improvement to this technical solution, a rotating block is rotatably connected to the top of the sliding base, an alarm device is provided on the top of the rotating block, a spare battery assembly is provided on the surface of the alarm device, and an alarm light is provided on the top of the alarm device.

[0008] As a further improvement to this technical solution, a speed reducer is fixedly connected to the top of the mobile platform, and a motor is provided on the side of the speed reducer away from the fixed block. The side of the speed reducer away from the motor is rotatably connected to a threaded rod, and the threaded rod passes through the fixed block near the speed reducer.

[0009] As a further improvement to this technical solution, several rotating shafts are rotatably connected to both sides of the alarm device. A camera is fixedly connected to the end of the rotating shaft near the motor, and an infrared probe is fixedly connected to the end of the rotating shaft away from the motor. Both the camera and the infrared probe have baffles on their surfaces, and antennas are provided on the side of the camera and the infrared probe away from the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The motor is started, driving the threaded rod to rotate via a reducer, which in turn moves the sliding base along the sliding rod. When the sliding base moves to a blind spot, the rotating block is activated, allowing the camera and infrared sensor to rotate 360° for comprehensive monitoring. When abnormal behavior or events are detected, the alarm device automatically sounds and notifies relevant personnel via a mobile terminal. In nighttime or low-light environments, the infrared sensor automatically activates to ensure clear monitoring. This device reduces the need for multiple cameras to achieve comprehensive monitoring, lowers costs, and simplifies the deployment and maintenance of the monitoring system, thus solving the problem of inability to perform comprehensive real-time monitoring.

[0021] Please see Figures 1-4As shown, this utility model provides a surveillance camera for subway transportation management, including a mobile platform 2. Several fixed blocks 24 are fixedly connected to the top of the mobile platform 2, and several sliding rods 21 are fixedly connected to the top of the mobile platform 2. A sliding base 1 is movably connected to the surface of the sliding rods 21. A spiral hole 26 is opened in the inner cavity of the sliding base 1, and a threaded rod 25 is rotatably connected to the inner cavity of the spiral hole 26. Several sliding holes 27 are opened on both sides of the spiral hole 26, and several pulleys 28 are provided in the inner cavity of the sliding holes 27. The sliding holes 27 are located on both sides of the sliding base 1, and the built-in pulleys 28 ensure smooth movement of the sliding base 1. 28 is located inside the sliding hole 27 to reduce friction and ensure smooth movement of the sliding base 1. The two ends of the threaded rod 25 are rotatably connected to the fixed block 24, and the sliding rod 21 is movably connected to the sliding hole 27. The inner cavity of the sliding hole 27 and the surface of the sliding rod 21 fit together and are both inverted trapezoidal in shape. The threaded rod 25 is driven to rotate by the motor 23, which drives the sliding base 1 to move along the sliding rod 21, so that the camera 16 can move in the horizontal direction, thereby achieving a wider range of monitoring. With the 360° rotation function of the rotating block 11, the camera 16 and the infrared probe 13 can perform all-round monitoring to ensure no blind spots.

[0022] Please see Figures 1-2 As shown, in this embodiment, a rotating block 11 is rotatably connected to the top of the sliding base 1, an alarm device 15 is provided on the top of the rotating block 11, a backup battery assembly 12 is provided on the surface of the alarm device 15, and an alarm light 14 is provided on the top of the alarm device 15. The backup battery assembly 12 ensures that it can still work normally in the event of a failure of the main power supply, thus ensuring the continuous operation of the system.

[0023] Please see Figure 1 As shown, further, a reducer 22 is fixedly connected to the top of the moving platform 2. A motor 23 is provided on the side of the reducer 22 away from the fixed block 24. The side of the reducer 22 away from the motor 23 is rotatably connected to the threaded rod 25. The threaded rod 25 passes through the fixed block 24 near the reducer 22. Connecting the motor 23 and the reducer 22 can ensure that the motor 23 is firmly connected to the threaded rod 25 through the reducer 22, and ensure that the motor 23 can accurately drive the threaded rod 25 to rotate when it rotates.

[0024] Please see Figure 1 and Figure 2As shown, specifically, several rotating shafts 19 are rotatably connected to both sides of the alarm device 15. A camera 16 is fixedly connected to the end of the rotating shaft 19 near the motor 23, and an infrared probe 13 is fixedly connected to the end of the rotating shaft 19 away from the motor 23. Both the camera 16 and the infrared probe 13 are provided with baffles 17 to protect them from damage. Antennas 18 are provided on the side of the camera 16 and the infrared probe 13 away from the rotating shaft 19. The alarm device 15 integrates the infrared probe 13, enabling it to continue working at night or in low light conditions, ensuring 24 / 7 monitoring. When abnormal behavior or events are detected, the alarm device 15 automatically issues an alarm and notifies relevant personnel via a mobile terminal, improving emergency response speed. The integration of the antenna 18 makes signal transmission more stable, ensuring the real-time performance and accuracy of monitoring data.

[0025] Please see Figures 1-4 As shown, in addition, the device can promptly detect potential security risks, such as abnormal behavior and intrusions, through its all-round monitoring capabilities, effectively preventing accidents from occurring. It reduces the need to install multiple cameras to achieve all-round monitoring, lowers costs, simplifies the deployment and maintenance of the monitoring system, has a high degree of automation, reduces the need for manual intervention, and improves the overall efficiency of the monitoring system.

[0026] In summary, the working principle of this solution is as follows:

[0027] When comprehensive monitoring is required, the starter motor 23, in conjunction with the reducer 22, drives the threaded rod 25 to rotate, thereby causing the sliding base 1 to move back and forth on the threaded rod 25 through the helical hole 26. When encountering a blind spot, the rotating block 11 on the sliding base 1 can ensure that the camera 16 and the infrared probe 13 can monitor the maximum area of ​​the site. The rotating shafts 19 on both sides of the alarm device 15 cause the camera 16 and the infrared probe 13 to rotate up and down to monitor the blind spots under their own bottom. When abnormal behavior or events are detected, the system will automatically issue an alarm and notify relevant personnel through a mobile terminal. The infrared probe 13 ensures the clarity of nighttime monitoring. The backup battery assembly 12 on the surface of the alarm device 15 will automatically start when there is a power outage to ensure that monitoring can continue during a power outage.
