[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A smart route verification device for railway tracks, such as Figures 1 to 7 As shown, the device includes a verification instrument body 100 mounted on a track 500 and a handheld remote controller. The front left and right sides of the verification instrument body 100 are connected to drive wheel assemblies 200 via folding components 600, the rear left and right sides of the verification instrument body 100 are connected to driven wheel assemblies 300 via folding components 600, and the middle of the verification instrument body 100 is equipped with a camera assembly 400 via folding components 600.

[0018] The main body 100 of the verification instrument includes a hollow main frame 101. A main control box 108 is located in the center of the main frame 101. A main control unit is installed inside the main control box 108. A power module 109 is installed in the main frame 101 behind the main control box 108. A camera assembly 400 is installed in the main frame 101 in front of the main control box 108.

[0019] The main control unit uses an embedded processor, which is responsible for the communication protocol processing, sensor data fusion and behavior decision-making of the entire system. It can simultaneously process commands such as motion control, image transmission, obstacle avoidance judgment and user command parsing. It uses an antenna to participate in signal transmission and reception, ensuring the reliability of control and video transmission.

[0020] The control communication link is based on 2.4G / 5.8G dual-band wireless communication, supports frequency hopping and encrypted transmission, and the control distance can reach 100 meters. In the video transmission link, the 405 video stream from the PTZ camera is compressed by H.265 encoding and transmitted by the vehicle receiver to the handheld remote controller. The remote controller pushes the video stream to the cloud server through the RTMP protocol, and the remote tablet terminal pulls the video stream from the cloud server through the RTSP protocol to achieve low-latency remote monitoring.

[0021] The handheld remote control, the drive wheel assembly 200, and the camera assembly 400 are all connected to the main control unit.

[0022] The handheld remote control is equipped with an LCD touchscreen, joystick, and buttons, supporting centralized control of device motion, lighting, gimbal camera, and video functions. It also features battery level display and speed setting indication.

[0023] The handheld remote control sends signals to the main control unit, which then controls the movement of the drive wheel assembly and the camera assembly. It can also receive signals from the camera assembly and transmit the images and videos captured by the camera assembly.

[0024] The bottom plate, top plate, and side plates of the main frame 101 are made of high-strength carbon fiber composite material. This material has the characteristics of low density, high specific strength, excellent corrosion resistance and fatigue resistance. While ensuring the rigidity and durability of the overall structure, it achieves the ultimate lightweighting of the equipment, with the weight of the whole vehicle controlled within 10 kg, laying the foundation for single-person carrying and operation.

[0025] A hinged opening plate 102 is hinged to the top plate of the main frame 101. The movable end of the opening plate 102 is locked by a locking piece 103 set on the top plate of the main frame, which makes it easy to store the folded camera assembly 400 inside the main frame.

[0026] Aluminum columns are also installed between the top plate and the bottom plate of the main frame 101 to enhance the support strength of the main frame.

[0027] An emergency stop button 104, a frame light 105, and a ranging radar 106 are respectively installed on the front and rear side plates of the main frame 101.

[0028] The emergency stop button 104 adopts a large mushroom head structure, which is easy to trigger. Once the equipment accidentally collides or comes into contact with an obstacle during operation, the emergency stop button on either side will immediately send the highest priority interrupt signal to the main control unit. The system will unconditionally cut off the power output of all motors and trigger emergency braking, achieving a millisecond-level response, thereby minimizing the risk of equipment overturning, derailment, or damage to personnel and surrounding facilities.

[0029] The ranging radar 106 features high precision and high response speed. By setting up a three-level obstacle avoidance protection mechanism, it automatically triggers different levels of safety response based on the distance to the obstacle. For example, when the distance between the vehicle and the obstacle is greater than 1 meter, the vehicle can drive normally; when the distance between the vehicle and the obstacle is greater than 0.5 meters and less than 1 meter, the vehicle automatically decelerates; and when the distance between the vehicle and the obstacle is less than 0.5 meters, the vehicle stops urgently, ensuring the safety of the equipment and the site.

[0030] The main control box 108 is also equipped with a voice broadcast module 111. The voice broadcast module 111 is connected to the main control unit and is used to receive signals sent by the main control unit and promptly complete prompts and broadcasts.

[0031] The power module 109 uses a 5Ah high-capacity lithium-ion battery with a standard voltage platform of 20V. It features high energy density, low self-discharge rate, and no memory effect, meeting the needs of frequent operation. The battery uses a universal "Dayi" battery interface, a sliding rail physical connection with anti-reverse insertion and self-locking anti-dislodgement characteristics, ensuring connection stability in vibration environments. This allows the battery to be removed and installed manually within seconds.

[0032] The battery itself is also equipped with a four-level LED power indicator and an indicator button. Users can simply press the indicator button to intuitively view the remaining power.

[0033] A push rod 113 is installed on the top plate of the main control box 108 via a U-shaped clip. The front and rear side plates of the main frame 101 are respectively provided with push rod connectors 107 for installing the push rod 113. Manual operation can be achieved by setting the push rod 113.

[0034] This utility model includes two working modes: automatic remote control and manual push rod. In automatic remote control mode, the operator sends control commands through a handheld remote control. The commands are wirelessly transmitted to the main control unit. After the main control unit parses the commands, it drives the motor and gimbal camera to perform the corresponding actions. In manual push rod mode, the operator installs the push rod on the main body of the verification instrument, switches to manual mode, disconnects the automatic control of the motor, and the operator directly pushes the equipment to move forward. The lighting and video functions continue to work normally.

[0035] The two working modes give the equipment strong environmental adaptability and reliability. In complex construction environments such as railway stations, tunnels, and bridges, there may be factors such as strong electromagnetic interference, metal obstructions, or satellite signal blind spots, which may cause unstable or even interrupted wireless remote control signals. The manual mode completely eliminates the dependence on wireless signals. Through pure mechanical direct control, it ensures that the verification device can be reliably pushed forward in any harsh electromagnetic environment or complex geographical environment, ensuring that the operation will not be interrupted due to technical reasons.

[0036] Moreover, in narrow construction areas with dense crowds or numerous equipment, in manual mode, operators can directly approach the equipment to push it, using visual observation to achieve the most accurate positioning and obstacle avoidance, greatly improving the safety of working in sensitive areas.

[0037] The drive wheel assembly 200 includes a drive wheel 201 and a drive wheel connecting shaft 202 slidably connected to the track 500. The other end of the drive wheel connecting shaft 202 is connected to the folding assembly 600. A motor 203 is installed on the drive wheel 201. A high-precision encoder is also provided on the motor 203, which can provide real-time feedback of speed and position information to achieve closed-loop control. A protective cover 204 is also provided on the inner side of the drive wheel 201 to cover the motor.

[0038] A white LED indicator is installed on the left drive wheel 201, and a purple LED indicator is installed on the right drive wheel 201, for visual direction differentiation.

[0039] The driven wheel assembly 300 includes a driven wheel 301 and a driven wheel connecting shaft 302 slidably connected to the track 500, and the other end of the driven wheel connecting shaft 302 is connected to the folding assembly 600.

[0040] The folding assembly 600 includes a flange seat 601 and a shaft end connector 602 hinged to the flange seat 601. A fastener 603 is provided between the flange seat 601 and the shaft end connector 602, which can lock the shaft end connector to the flange seat after folding.

[0041] The flange seat 601, shaft end connector 602, and fastener 603 are made of high-strength aerospace aluminum alloy and have undergone matte oxidation treatment, combining lightweight and high reliability.
