[0017] Based on the same inventive concept, an embodiment of the present invention further provides a road safety warning method based on a road guard, comprising: Collision warning: Several road guards are installed on the top of the guardrails on both sides of the road, and the interval between two adjacent road guards is 20-25m. When the vibration sensor of the road guard detects a collision signal, the positioning module automatically locates the position information of the road guard, and sends the collision signal and position information to the cloud platform through the communication module. Taking the collision point as the starting point, the cloud platform sends an early warning signal to the guards on both sides of the road within 2 kilometers in the direction of the oncoming vehicle, and controls the light indication module of the road guard to flash as a reminder, which can be red and blue light flashing alternately for 10 minutes. In this embodiment, the road is specifically a one-way street. For two-way streets, etc., the cloud platform takes the collision point as the midpoint and sends an early warning signal to the road guards within 2 kilometers in the direction of the oncoming vehicle. At the same time, the video surveillance module on the scene is controlled to shoot and upload the on-site video / picture. The cloud platform then pushes the accident information to the information board for early warning. The cloud platform links the tweeter through IP broadcasting to give a voice prompt warning, which can eliminate the on-site accident in time and avoid secondary accidents. At the same time, the damaged guardrail can be traced and compensated in time; Fog area guidance: Several road guards are installed on the top of the guardrails on both sides of the road. The front-end meteorological sensing equipment sends local climate information to the cloud platform. When the front-end meteorological sensing equipment detects foggy weather, the cloud platform sends a guidance instruction to control the light indication module of the road guard to flash for light guidance. Specifically, the fast flashing yellow light can be turned on for all road guards. Road sign: Several road guards are installed on both sides of the road in areas with poor visibility such as cliffs, water, and turning areas. The cloud platform controls the light indication modules of several road guards to flash simultaneously to indicate the road surface. Specifically, it can be a slow flash light to serve as a warning.

[0018] One-touch alarm: In case of a traffic accident but no collision with the guardrail, the user presses the one-touch alarm button of the road guard, and the red and blue lights of the light indicator module flash continuously to warn the vehicles behind to pay attention to safety. It is also convenient to quickly lock the alarm point through the surveillance camera at night. At the same time, the built-in voice alarm module sends out: "The alarm message has been uploaded". After the upload is successful, the guardrail guard immediately sends out: "The alarm message has been received, please go to the outside of the guardrail and wait for rescue". The communication module sends the alarm information and location information to the cloud platform, and the cloud platform sends the alarm information and location information to the command center. The command center automatically dispatches nearby maintenance vehicles and traffic police for rapid on-site disposal. As above, the cloud platform sends an early warning signal to the road guard within 2 kilometers in the direction of the oncoming vehicle, controls the light indicator module of the road guard to flash as a reminder, and controls the on-site video surveillance module to shoot and upload on-site video / pictures. The cloud platform then pushes the accident information to the intelligence board for early warning. Furthermore, the built-in audio intercom module of the road guard can perform real-time voice and video intercom.

[0019] The road safety warning system and method based on road guard of the present invention can issue a light warning when a collision occurs, and upload the accident information to the cloud platform at the same time, and link the information board, camera and speaker to issue a warning, so as to eliminate the accident in time and avoid secondary accidents. At the same time, the damaged guardrail can be traced and compensated in time; fog area guidance can be carried out on foggy days, and road surface indication can be carried out in sections with poor visibility to reduce the occurrence of accidents and improve road safety; by setting a one-key alarm, when an accident occurs without hitting the guardrail, the user can issue an alarm with one key, send location information and issue a light warning, which can be used for different road emergencies and has strong practicality.

[0020] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
