[0039] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This utility model is described in detail.
[0040] Example 1:
[0041] A smart inspection device for underground utility tunnels in high-speed railway stations is characterized by comprising a slide rail system, on which a high-definition camera pan-tilt unit and an Internet of Things (IoT) sensor are mounted. The high-definition camera pan-tilt unit and the IoT sensor are connected to a control system via a wireless network. The control system is used to receive instructions from a back-end management platform.
[0042] It also includes an embedded device connected to the slide rail system via a serial port, the embedded device communicating with the control system and the IoT sensor via a wireless network;
[0043] The IoT sensor transmits data to the backend management platform in real time through the control system, and the embedded device listens to messages from the backend management platform and controls the slide rail system through the control system.
[0044] Working principle:
[0045] The overall structure of this utility model adopts a track-type monitoring method, as shown in the attached figure. Figure 1 As shown, the equipment includes a sliding rail system, a high-definition camera pan-tilt unit, IoT sensors, embedded devices, a control system, and a back-end management platform. The high-definition camera pan-tilt unit is fixed on the sliding rail system, and its movement is driven by the sliding rail system.
[0046] High-definition camera pan-tilt units are mainly used to collect and transmit image and video data in underground utility tunnels. They can rotate and monitor in multiple dimensions, including left, right, top, and bottom, expanding the monitoring field of view and reducing blind spots.
[0047] The high-definition camera pan-tilt unit uses wireless control. It receives instructions from the back-end management platform through a wireless network access control system and changes the rotation direction, rotation angle, and focal length of the lens according to the instructions.
[0048] The high-definition camera pan-tilt unit has data transmission capabilities. After completing the monitoring data collection, it transmits the data to the backend management platform through the control system.
[0049] High-definition camera pan-tilt units collect video data from multiple angles, effectively reducing blind spots and improving the safety and reliability of operation and maintenance management.
[0050] The embedded device has a built-in serial port, i.e., a GPIO port, which connects to the slide rail system driver and communicates with IoT sensors and the back-end management platform via a wireless network. The high-definition camera pan-tilt unit and IoT sensors are responsible for collecting monitoring data from the underground utility tunnel space.
[0051] Furthermore, in the embodiments, the slide rail system may include a base, a slide rail 1, a timing belt, a stepper motor 2, a slider 3, and a switching power supply.
[0052] The stepper motor 2 is disposed on one side of the base. The stepper motor 2 includes a motor driver, which is powered by the switching power supply.
[0053] The synchronous belt is equipped with a pulley, which is driven by the motor to move the synchronous belt. The slider 3 is installed on the top of the synchronous belt.
[0054] The base is fixedly mounted with a slide rail 1, the bottom of the slider 3 is slidably connected to the slide rail 1, and the high-definition camera gimbal is mounted on the top of the slider 3.
[0055] In this embodiment, the synchronous belt transmits motion through the meshing of equidistant transverse teeth on its inner surface and corresponding grooves on the pulleys. The stepper motor 2 is powered by a switching power supply and precisely controlled by a motor drive. The stepper motor is connected to the pulley of the synchronous belt, and the rotation of the motor rotor drives the synchronous belt to move. The slider 3 can slide along the slide rail 1 and is connected to the synchronous belt. The synchronous belt pulls the slider 3, causing displacement, which in turn synchronously moves the high-definition camera pan-tilt unit connected to the slider 3.
[0056] Furthermore, in the embodiments, the embedded device can be connected to the motor driver via a serial port and receive instructions from the back-end management platform through the control system to control the stepper motor 2.
[0057] Furthermore, in the embodiments, the embedded device can be considered to listen to the back-end management platform messages through the control system, decode the received messages to obtain control commands, and generate a specific PWM wave through the serial port to control the stepper motor 2.
[0058] In this embodiment, the embedded device connects to IoT sensors and a backend management platform via a wireless network, and to the synchronous belt slide rail motor driver via a device serial port. The embedded device listens for messages from the backend management platform through the control system. Upon receiving a message, it decodes it to obtain control commands and generates a specific PWM wave through the GPIO port to control the rotation direction and speed of the motor, thereby changing the displacement direction, speed, and position of the synchronous belt slide rail slider.
[0059] The terms used in this embodiment are defined as follows:
[0060] GPIO ports, or General Purpose Input / Output ports, are interfaces used by computers and other digital systems for general signal transmission.
[0061] PWM (Pulse Width Modulation) is a technique that controls power and electrical output by changing the pulse width (i.e., the duration of the high-level signal). PWM waves are commonly used in applications such as controlling motor speed, adjusting brightness, and generating audio.
[0062] Furthermore, in the embodiments, a first waterproof box 4 is provided on one side of the slide rail system, and a power cord hole 6 is provided on the side of the first waterproof box 4 for extending the power cord of the switching power supply.
[0063] The switching power supply, the stepper motor 2, the embedded device, and the IoT sensor are placed inside the first waterproof box 4.
[0064] Furthermore, in the embodiments, it can be considered that the back of the first waterproof box 4 is provided with a first interface 5, and one end of the stepper motor 2 is fixedly connected to the first interface 5.
[0065] Furthermore, in the embodiments, a waterproof box cover can be hinged to the top of the first waterproof box 4.
[0066] In this embodiment, the first waterproof box 4 has an IP66 waterproof rating and can be divided into two parts: a waterproof box body and a waterproof box cover.
[0067] The waterproof box cover is located on top of the waterproof box body and can be opened manually. It is hinged to the waterproof box body by stainless steel screws. The waterproof box body is a one-piece molded rectangular box-shaped object used to store various devices, including embedded devices, switching power supplies, various IoT sensors and junction boxes. The junction box can be connected to the power supply in the inspection room. All wires extend through the power cord hole 6. The stepper motor 2 and the inspection equipment are powered through the connection junction box. A transformer is added for those requiring low voltage power supply.
[0068] One end of the stepper motor 2 is fixedly connected to the first interface 5 of the first waterproof box 4, which can ensure the stability of the stepper motor 2.
[0069] Furthermore, in the embodiments, the top of the slider 3 is provided with a second waterproof box 7, and the high-definition camera gimbal is installed on the second interface 8 inside the second waterproof box 7.
[0070] In this embodiment, the second waterproof box 7 has the same specifications as the first waterproof box 4 and has an IP66 waterproof rating. The main body can be divided into two parts: a waterproof box body and a waterproof box cover. The difference is that the second waterproof box 7 is used to protect the high-definition camera pan-tilt unit.
[0071] When in use, the lower half of the camera of the HD camera pan-tilt unit is placed on the second interface 8, while the upper half of the camera, i.e. the video recording part, is exposed to the outside, which will not affect the video recording function.
[0072] Furthermore, in the embodiments, the IoT sensor may include a temperature sensor, a humidity sensor, and a smoke sensor. The temperature sensor, the humidity sensor, and the smoke sensor communicate with the embedded device via a wireless network and transmit the data to the back-end management platform in real time through the control system.
[0073] In this embodiment, the IoT sensor selects its deployment location by combining the track length and the sensor's monitoring range in order to achieve coverage of the main space of the utility tunnel.
[0074] IoT sensors communicate with embedded devices via wireless networks and transmit the data to the back-end management platform in real time through the control system.
[0075] The advantages of this utility model are as follows:
[0076] 1. By integrating a small sliding rail 1 with a high-definition camera pan-tilt unit, the underground utility tunnel space of the high-speed railway station can be monitored from multiple angles, effectively reducing blind spots caused by objects and improving the quality of inspection.
[0077] 2. By integrating functional modules such as high-definition camera pan-tilt units, IoT sensors, and sliding rails, the size of the equipment can be effectively reduced, making it suitable for the confined underground utility tunnel spaces of high-speed railway stations. Furthermore, by utilizing multiple sensors to acquire diverse monitoring data, the accuracy of inspections can be improved, and the application scenarios of the equipment can be expanded.
[0078] 3. The high-definition camera pan-tilt unit is moved by a small sliding rail 1, expanding the monitoring area of the equipment. Compared with traditional surveillance cameras, it can effectively reduce the number of equipment deployment nodes, reduce the difficulty of equipment deployment, management, and equipment costs.
[0079] 4. By using the first waterproof box 4 and the second waterproof box 7 to protect the key components in the equipment, the equipment can be guaranteed to operate normally in a humid environment, effectively improving the stability of the equipment.

Then, set static IP addresses for each embedded device and connect it to the wireless network.
[0087] In this step, the first waterproof box 4 has a built-in terminal block that is connected to the power supply of the inspection room. The stepper motor 2 and the inspection equipment are both connected to the terminal block for power supply. A transformer is added if low voltage power supply is required.

[0093] In manual control mode, inspection personnel can manually control the movement of the slide rail slider through the backend management platform page, and manually control the acquisition of images and IoT sensor data during the movement process.
[0094] Step 5: Data Transmission and Processing
[0095] After completing the inspection data collection, the device automatically uploads the monitoring data to the control system via wireless network, including monitoring data from the high-definition camera pan-tilt unit and data collected by IoT sensors. The control system processes and analyzes the collected data in real time, extracts key information, and sends the processed data to the backend management platform.
[0096] Step 6: Data Display and Early Warning
[0097] Based on the received data, the backend management platform implements alarm and early warning functions, displays the processed data and images to the inspection personnel in real time, and continues to monitor the input information of the inspection personnel.

[0101] (3) The control system generates control commands based on the inspection instructions and transmits them to the high-definition camera pan-tilt unit, IoT sensor, and embedded device respectively.
[0102] (4) After receiving the instruction, the terminal device performs inspection. The high-definition camera pan-tilt unit and the Internet of Things sensor collect image data and environmental information such as temperature and humidity in the underground pipe gallery space, and transmit the image information and sensor data to the control system respectively. The embedded device generates PWM wave signal according to the instruction to control the operation of the slide rail system and monitor the operation status of the slide rail system.
[0103] (5) The control system analyzes and processes the received image data and sensor data to form inspection result data, and transmits the processed inspection results to the back-end management platform and stores the data.
[0104] (6) The backend management platform displays the inspection results to the inspection personnel.
