Description

Technical Field

[0001] This utility model relates to the technical field of road traffic safety protection devices, specifically a smart cone device for road traffic safety protection. Background Technology

[0002] With the development of society and the economy, and the increase in the number of motor vehicles, many traffic accident cases are handled without completely disrupting traffic in order to avoid affecting normal traffic flow. According to relevant regulations, accident investigators are required to place vehicle intrusion warning devices at the accident scene in the direction of oncoming traffic, reserving a safe zone for them. Because roads, especially highways and urban expressways, have high traffic volumes and high vehicle speeds, there is a certain probability that vehicles will intrude into the safe zone. This poses a significant safety risk to police officers and auxiliary police handling traffic accidents. To ensure timely alerts when vehicles intrude, traffic cones and other vehicle intrusion warning devices are typically placed at the edge of the safe zone. For example, the patent with publication number CN213814992U discloses an intelligent traffic cone. The cone is equipped with an infrared sensor, an LED warning light, and a broadcasting device. The infrared sensor 21 has a sensing range of 500 meters. Once a vehicle passes through the adjacent lane, the sensing signal of the infrared sensor 21 is transmitted to the cone control module 10, and a warning sound is emitted through the broadcasting device. This device can effectively protect the personal safety of staff when handling traffic accidents.

[0003] With the adjustment of safety protection regulations for safety protection zones, existing traffic protection devices, in addition to warning vehicles that have entered the warning zone, also need to collect video or images of vehicles entering the safety protection zone, or form on-site networks. The existing traffic cones, which only have an oncoming vehicle alarm function, are no longer adequately equipped to meet the requirements of the latest safety protection zone regulations.

Detailed Implementation

[0010] like Figures 1-7 As shown, this application includes a smart traffic cone device for road traffic safety protection, comprising: a base 1, a cone body 2, a head functional module 3, a lifting mechanism 4, a battery module 5, and a handle 6. The head functional module 3 is mounted on top of the cone body 2 based on a head housing 8. The base 1 and the cone body 2 are integrally molded using plastic material, which serves as a waterproof material to protect the internally installed modules from damage.

[0011] The head-mounted functional module 3 includes: a controller, a ranging module 31, an operation panel 32, a camera, a positioning module 34, an IoT communication module 35, a data upload module 36, a gyroscope 37, an audible and visual alarm module, a radar module 39, and a supplementary light. The ranging module 31, camera, gyroscope 37, positioning module 34, IoT communication module 35, data upload module 36, and radar module 39 are electrically connected to the controller. The head-mounted housing 8 is waterproof and dustproof, reducing the probability of damage to internal components from external impacts or severe weather conditions such as rain and snow.

[0012] Because the head functional module 3 in this application integrates chips for multiple functional modules, and because the head functional module 3 needs to be positioned above the conical body 2, the size of the head functional module 3 is limited and cannot be too large, otherwise it will affect the stability of the cone and make the overall device too heavy. Therefore, the design challenge lies in how to reasonably arrange multiple modules within the limited size of the head housing 8.

[0013] To minimize interference between these modules and to enhance user convenience, their structural placement needs to be carefully designed. The positioning module, based on GPS or BeiDou, receives signals from satellites. Therefore, to ensure more accurate signal reception, the antenna of the positioning module 34 is positioned at the top of the head functional module, and the corresponding chip is also located at the top of the inner cavity of the head housing 8. Similarly, the gyroscope 37, used to monitor the tilt angle of the cone, also needs to be mounted at the top of the inner cavity of the head housing 8 to ensure more accurate detection results.

[0014] To ensure the camera has a sufficient field of view, it is positioned relatively high within the head housing 8. The data upload module 36 in this application is based on a 4G or 5G module and requires a SIM card. Therefore, space must be reserved for the SIM card slot, and the data upload module is located below the camera. Similarly, the ranging module 31 is based on a UWB ranging module. Since an external antenna is required for UWB ranging, space must also be reserved for this antenna. In this embodiment, the ranging module 31 is also positioned below the camera.

[0015] The head housing is designed as a polyhedron with multiple sidewalls, each side serving a different function, providing operating space for the user. Specifically, in this application, the head housing is a stepped polyhedron, wider at the top and narrower at the bottom. The larger upper polyhedron protects the lower polyhedron and helps to drain rainwater during rainy weather. The bottom end face of the head housing has the same dimensions as the top end face of the cone body, allowing the head housing 3 to be stably mounted on top of the cone body 2. The top end face of the head housing 3 is horizontally positioned, with the top surface extending horizontally in the direction of the camera to form an eaves shape, preventing direct sunlight from hitting the camera and also helping to drain rainwater during rain.

[0016] like Figure 4 and 5 In the illustrated embodiment, the head housing 3 is designed as a hexahedron, comprising upper and lower hexahedrons, and the conical body 2 has a frustum-shaped structure. The centers of gravity of all three are on the same vertical line, ensuring stable placement. An operation panel is provided on the top surface of the head housing 3 for user convenience. Two cameras are respectively mounted on a functional surface of the upper hexahedron; the SIM card slot 361 of the data upload module 36 and the external antenna connector 311 of the ranging module 31 are mounted on the same functional surface of the lower hexahedron; the radar module 39 and the front camera 331 are mounted in the same direction, with the radar located on the lower hexahedron; the charging interface 9 is mounted on a functional surface of the lower hexahedron.

[0017] In this embodiment, the controller is implemented based on the AX620 chip. The AX620 chip provides the following interfaces and functions: two sensor input interfaces for connecting to the front and rear camera modules; a UART serial port for connecting to the BeiDou positioning module; a TF card slot: standard configuration includes a 64GB TF card, supporting plug-and-play replacement; an external network port, a standard RJ45 interface, 1000Mbase-T; an RS485 port for external device expansion and debugging, supporting a maximum speed of 460800bps; a serial port for connecting to the radar module; and audio output for driving the speaker to emit voice and alarm prompts.

[0018] The data upload module 36 is based on existing 4G or 5G modules, supports communication between the smart cone and the backend platform, provides a data port for long-distance data upload, and can be connected to the controller via a USB port.

[0019] The ranging module 31 is implemented based on existing models capable of ranging functions. In this embodiment, a UWB ranging module of model MK8000PA is used, which can support real-time point-to-point ranging within a distance of 300 meters, providing hardware support for the ranging requirements of the cone. The UWB ranging module is connected to the controller via a UART port.

[0020] The gyroscope 37 is based on the existing SH3001 gyroscope and provides hardware support for the collision alarm of the smart cone. The gyroscope 37 is connected to the controller via an I2C port.

[0021] The IoT communication module 35 is implemented based on the existing sub-1G low-speed wireless communication module. In this embodiment, an RFM380F64 sub-1G low-speed wireless communication module is used, with a communication rate of 115200bps. Equipped with a built-in antenna, it can meet the communication needs of devices within a radius of 500 meters; it is connected to the controller 1 via a UART interface. This application provides hardware support for networking between field devices using the sub-1G low-speed wireless communication module.

[0022] The positioning module 34 is based on the existing BeiDou positioning module and can provide hardware support for the positioning needs of the cone. The BeiDou module is connected to the controller 1 via a UART serial port.

[0023] The controller is installed inside the head housing 8, and the operation panel 32 is horizontally set at the top of the head housing 8 for easy operation by staff.

[0024] like Figure 6 As shown, the operation panel 32 includes: a display screen 321, status indicator lights 322, operation buttons 323, and indicator arrows 324; the status indicator lights 322, indicator arrows 324, and operation buttons 323 are arranged around the display screen 321; the indicator arrows 324 are used to point in the direction of the accident scene. The display screen 321 can be implemented based on an OLED display screen in the prior art.

[0025] In this application, the OLED display screen 321 and operation buttons 323 on the operation panel provide the hardware foundation for the display and operation of the smart cone. Status indicator lights 322 provide the hardware foundation for displaying the status of certain modules or functions when needed; the specific status display implementation is based on existing technology. In this embodiment, the display screen 24 uses a monochrome dot matrix OLED screen and communicates with the controller via an SPI interface. The specific wiring method between the operation buttons 323 and the controller 31 or other devices is configured according to actual needs.

[0026] The camera includes a front camera 331 and a rear camera 332, which are positioned horizontally at a 180° angle. The acquisition direction of the rear camera 332 is the same as the direction indicated by the arrow 324. The camera 33 can be implemented using any existing camera module. In this embodiment, both the front camera 331 and the rear camera 332 use 4-megapixel video sensors, and the interface between the front camera 331 and the rear camera 332 and the controller is MIPI CSI.

[0027] The radar module 39 has the same acquisition direction as the front-facing camera 331. In this embodiment, the radar module 39 uses a millimeter-wave radar with an 80GHz operating frequency, which is different from the 77GHz frequency band commonly used in vehicles to avoid interference. The radar module 39 can be implemented using a radar module with speed measurement function from the prior art, such as the MR76S radar module. The radar module 39 is connected to the controller via a UART port.

[0028] This application marks the placement direction of the smart cones by printing or pasting indicator arrows 324 on the operation panel 32. Based on the direction indicated by the indicator arrows 324, the acquisition directions of the front camera 331, the rear camera 332, and the radar module 39 are set. When placing the smart cones, the indicator arrows 324 are pointed towards the accident scene. The rear camera 332 can collect video data from the accident scene, while the radar module 39 and the front camera 331 can simultaneously collect data from the upstream direction of the accident scene.

[0029] The cone-shaped body 2 has a shell-like structure with a lifting port 21 at the top, connecting to the inner cavity of the shell-like structure. The lifting mechanism 4 is installed inside the inner cavity of the cone-shaped body 2, with its top extending out of the lifting port 21. The head housing 8 is installed at the top of the lifting mechanism 4, located above the lifting port 21. In this embodiment, the lifting mechanism 4 is based on an electric lifting rod. Specifically, a separate lifting control button is provided for the lifting mechanism 4. A lifting control button is selected from the operation buttons on the control panel 32, and the lifting control button is electrically connected to the electric lifting rod via a wire to control the raising and lowering of the lifting mechanism 4.

[0030] By setting up the lifting mechanism 2, the height position of the head function module 3 can be changed according to actual needs. This can change the monitoring range of modules such as cameras and radar, as well as the warning height of the red and blue flashing lights, thereby improving the warning effect and making the device more practical.

[0031] The audible and visual alarm module is equipped with a speaker 381 and a red and blue flashing light 382, ​​providing hardware support for sound and light alarms.

[0032] In this embodiment, the speaker 381 and the front camera 331 are mounted on one side, and the speaker 381 is connected to the external audio codec output of the controller. The red and blue strobe light uses high-brightness LED beads, paired with transparent red and blue housings to achieve red and blue light flashing. The red and blue strobe light is located on the top of the head housing 8 and is used to provide a light warning to passing vehicles on the road. The specific control method for the red and blue strobe light 382 can be selected from the controller 31 or an independent control MCU; the specific implementation can be based on existing red and blue strobe light control methods according to actual needs.

[0033] The handle 6 is located on the top surface of the head housing 8. In this embodiment, the handle is arc-shaped, with both ends connected to the head housing 8 and the middle part suspended above the top surface of the head housing 8, ensuring that it will not affect the use of other modules on the head housing 8.

[0034] The supplementary lights include a front supplementary light 3101 and a rear supplementary light 3102. The front supplementary light 3101 is mounted on the same side as the front camera 331, and the rear supplementary light 3102 is mounted on the same side as the rear camera 332, ensuring that the camera can collect clear data even when the light is insufficient.

[0035] The base 1 is located below the cone-shaped body 2, and the battery module 5 is located inside the cavity of the base 1. The power module 5 supplies power to all other modules. The specific battery module 5 can be implemented based on existing battery modules. Placing the battery module at the bottom of the cone-shaped body 2 increases the total weight of the smart cone bottom through the weight of the battery module 5 and its casing, improving its stability and reducing the probability of the device tipping over due to strong winds. The battery casing is a sealed, waterproof shell to prevent damage to the battery module 5 from water immersion. Additionally, this application includes a charging interface 9 to provide a port for battery charging; the connection between the charging interface 9 and the battery module 5 can be implemented using existing technology.

[0036] The base 1 is equipped with casters 7 at its bottom for easy placement and deployment of the smart cones. The outer surface of the cone body 2 is provided with a reflective film to improve the cone's visibility and recognizability.
