[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-5 As shown, a magnetic guardrail column cap for use in multiple scenarios includes several guardrail columns 1, a column cap 2 is provided at the top of the guardrail column 1, the column cap 2 is connected to the top of the guardrail column 1 through a magnetic base 3 at the bottom, the column cap 2 includes a transparent semicircular or rectangular shell 6, the transparent shell 6 can be made of materials such as acrylic or plexiglass, a light-emitting device for early warning and guidance is provided inside the transparent shell 6, a control device for controlling regular light emission is provided on one side of the light-emitting device, and the light-emitting device and the control device are circuit-connected to a built-in battery 8.

[0030] A sensor for monitoring whether there are vehicles passing by is also provided in the column cap 2. The sensor is connected to the light control device. When the sensor detects that there are vehicles passing by on the road, the control module receives the signal, executes the corresponding strategy, triggers the LED light group 4 to work, and provides dynamic warning for the moving vehicles; when there are no vehicles moving, the device is in low power consumption operation mode, and the LED light group 4 does not work.

[0031] The magnetic base 3 is a magnetic suction cup, and the column cap 2 is detachably connected to the top of the guardrail column 1 through the magnetic suction cup. The magnetic suction cup design facilitates the disassembly and assembly of the column cap and simplifies the difficulty of disassembly and assembly.

[0032] The light emitting device is an LED light group 4.

[0033] The control device is an STM32 microcontroller 7. ST's ultra-low power ARM Cortex-M0 microcontroller series products are based on the ultra-low power ARM Cortex-M0 processor core, integrating enhanced technologies and functions. This series of microcontrollers shortens the performance gap between devices using 8-bit and 16-bit microcontrollers and devices using 32-bit microcontrollers, and can realize advanced and complex functions on economical user terminal products. The control device can also use an open source RISC-V microprocessor. RISC-V (RISC-FIVE) is an open instruction set architecture (ISA) based on the principle of reduced instruction set computing (RISC). V represents the fifth generation of RISC chips. Traffic light control systems based on RISC-V microprocessors can achieve more efficient and intelligent traffic management, improve traffic flow and safety. RISC-V microprocessors have the characteristics of openness, flexibility, and customizability, which can meet the needs of different traffic scenarios. At the same time, they can also be combined with sensors, communication technologies, etc. to achieve more accurate control and data acquisition.

[0034] The sensor is a microwave sensor 5, which is a common sensor. The microwaves emitted by the transmitting antenna will be absorbed or reflected when encountering the object to be measured, causing the power to change. If the microwaves passing through the object to be measured or reflected by the object to be measured are received by the receiving antenna and converted into electrical signals, which are then processed by the measuring circuit, microwave detection is realized, and information such as the existence, movement speed, distance, angle, etc. of the object can be sensed.

[0035] The transparent shell 6 is semi-cylindrical or rectangular in shape as a whole, and the side elevation can be more conveniently removed and placed stably on the road surface.

[0036] Working process and principle of this utility model:

[0037] The utility model includes physical components such as a semi-cylindrical or rectangular body, a microwave sensor 5, an STM32 microcontroller 7, an LED light group 4, a built-in battery 8, and a bottom magnetic base 3. The bottom of the column cap 2 is a magnetic base, and the side can also be a base for vertical installation. The top of the device is a semi-circular transparent shell 6, which is equipped with an LED light group 4, a battery 8 in the middle, and the battery 8 can be a storage battery or a solar cell. The bottom is a magnetic suction cup, which can be fixed to the top of the guardrail by magnetic attraction. The LED light group 4 is powered by a built-in battery, and the microwave sensor 5 monitors whether there are vehicles passing by.

[0038] When the microwave sensor 5 detects that there is a vehicle passing by on the road, the stm32 microcontroller 7 receives the signal and executes the corresponding strategy, triggering the LED light group 4 to work regularly or continuously to provide dynamic warning for the moving vehicles; when there is no vehicle driving, the device is in low power consumption operation mode, and the LED light group 4 does not work.

[0039] When a vehicle breaks down while driving on the road, the driver and passengers can remove the column cap 2 as a whole and install it vertically on the road behind the vehicle. When the vehicle is on a special road section such as a curve, multiple column caps 2 can be removed and placed on the road to achieve a longer-distance warning and ensure the safe driving of the following vehicle. This device adopts an independent structure and meets the needs of different usage scenarios through different placement methods.

[0040] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes the embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
