[0038] The device body includes a traffic sign and a drive mechanism. The traffic sign is detachably connected to the drive mechanism, which is used to drive the traffic sign to move. The traffic sign is a conical traffic sign barrel, and the drive mechanism is a cabin-type four-wheel drive vehicle. The bottom of the conical traffic sign barrel is threadedly connected to the top of the cabin-type four-wheel drive vehicle. Specifically, a screw is fixedly connected to the bottom of the conical traffic sign barrel, and a threaded hole is opened on the top of the cabin-type four-wheel drive vehicle corresponding to the screw. The screw is threadedly connected to the threaded hole, thereby realizing the detachable connection of the bottom of the conical traffic sign barrel to the top of the cabin-type four-wheel drive vehicle.

[0039] The control system includes a main control unit module, a wireless control transmission and processing module, a wireless control receiving module, and a sensor module. In this embodiment, the main control unit module is an embedded microprocessor, preferably an STM32H series high-performance microcontroller, which is located at the bottom of the cabin-type four-wheel drive vehicle. The wireless control receiving module is located on the cabin-type four-wheel drive vehicle.

The touch screen display has a built-in Wi-Fi network function, and operators can manually set commands by setting the touch screen display.

[0041] The drive mechanism, wireless control transmitting and processing module, wireless control receiving module, and sensor module are all electrically connected to the main control unit module.

[0042] The wireless control transmitting and processing module is used to set control commands and transmit control command signals to the wireless control receiving module; in this embodiment, the control commands include road closure commands and return commands.

[0045] The inertial navigation module is used to collect the relative trajectory of the cabin-type four-wheel drive vehicle. By collecting the relative trajectory of the cabin-type four-wheel drive vehicle through the inertial navigation module, and by detecting the changes in acceleration and angular velocity of the vehicle during movement, combined with the initial position information, the vehicle's travel route is calculated.

[0046] The angle measurement module is used to collect the heading angle of the cabin-type four-wheel drive vehicle; collecting the heading angle of the cabin-type four-wheel drive vehicle helps to determine the direction of the vehicle and ensure that it travels along the predetermined route.

[0047] The nine-axis gyroscope module is used to collect the running speed and acceleration of the cabin-type four-wheel drive vehicle. The nine-axis gyroscope typically includes an accelerometer with three axes, a gyroscope with three axes, and a magnetometer with three axes.

Specifically, the UWB positioning module is installed inside the four-wheel drive vehicle, and its position and distance to the wireless charging base station are obtained through the UWB positioning module.

[0049] The main control unit module is used to control the drive mechanism to drive the traffic sign to the designated position according to the control command signal and the acquisition result signal.

In this embodiment, the lithium battery pack is a high-capacity lithium battery. By mounting the wireless charging receiver on the drive mechanism (i.e., the cabin-type four-wheel drive vehicle), it receives power from the wireless charging transmitter base station and transfers it to the lithium battery pack for storage. This solves the problem of the intelligent, automatically blocking traffic cones lacking power supply when operating outdoors, fundamentally overcoming the drawbacks of traditional remote-controlled wired charging traffic cones, and facilitating user operation and maintenance.

[0051] Specifically, the wireless charging base station includes an electrically connected power input control terminal, a wireless transmitting circuit, and a magnetic induction transmitting coil; the wireless charging receiver includes an electrically connected magnetic induction receiving coil, a wireless receiving circuit, and an induction power output terminal; an external power supply powers the wireless charging base station through the power input control terminal, the wireless transmitting circuit converts the DC power obtained from the power input control terminal into high-frequency AC power, drives the magnetic induction transmitting coil to generate an alternating magnetic field, induces a current in the magnetic induction receiving coil on the driving mechanism, and obtains a stable DC power after rectification and filtering by the wireless receiving circuit. The induction power output terminal provides the DC power to the battery charging circuit control circuit, which adjusts the charging parameters according to the state of the lithium battery pack, and finally, the lithium battery pack completes the charging process.

[0052] As a preferred embodiment, the system also includes a camera module mounted on the drive mechanism.

In this embodiment, the camera module is a high-definition camera. The high-definition camera ensures clear video recording quality when the four-wheel drive vehicle is in operation. Specifically, the camera module is mounted on the drive mechanism (i.e., the mobile four-wheel drive vehicle) and can capture real-time visual information about the surrounding environment, including but not limited to road conditions, obstacle locations, traffic signs, and the location of wireless charging base stations.

[0053] In addition, after receiving the return command, the main control unit module reads the image data from the camera module, performs calculations within the main control unit module, uses visual algorithms to identify the characteristics of the wireless charging base station, and controls the cabin-type four-wheel drive vehicle to run to the wireless charging base station.

[0054] As a preferred option, it also includes a network communication module, a cloud server, and a remote monitoring server;

In this embodiment, the network communication module is a WiFi wireless communication module, and the remote monitoring server is a computer.

[0057] As a preferred embodiment, the device body also includes a solar-powered warning light, which is detachably mounted on top of the traffic sign. In this embodiment, the bottom of the solar-powered warning light is threadedly connected to the top of the traffic sign via a screw, thereby achieving a detachable connection of the solar-powered warning light to the top of the traffic sign. The solar-powered warning light provides additional visual warnings, enhancing safety, and is particularly suitable for use at night or in low-visibility conditions.

[0058] The working principle of this utility model is as follows:

[0059] In use, before the four-wheel drive vehicle is put into operation, the traffic cones and solar-powered warning lights are installed on the vehicle and placed in front of the wireless charging base station. The lithium battery pack is then charged via the wireless charging receiver. When road closure is required, the wireless control transmitting and processing module sends a road closure command and mode to the wireless control receiving module and sends a control command signal back to the main control unit module. The sensor module collects the position data and operating parameters of the drive mechanism and sends the collection result signal back to the main control unit module. Upon receiving the control command signal and the collection result signal, the main control unit module, based on the set location point and planned path, controls the four-wheel drive vehicle to drive the traffic cones away from the wireless charging base station and move to the designated location, completing the road closure operation. When it is necessary to return to the wireless charging base station, the wireless control transmitting and processing module sends a return command signal to the wireless control receiving module. The main control unit module then controls the four-wheel drive vehicle to move to the wireless charging base station and begin charging the lithium battery pack via the wireless charging receiver, thus realizing the autonomous movement and return charging of the traffic cones.
