An intelligent highway guardrail collision device and its control method

Abstract

The invention relates to an intelligent expressway guardrail collision device. The intelligent expressway guardrail collision device is installed on the side, close to vehicles, of a guardrail of an expressway and comprises a device body, a vibration sensor, a controller, an elastic connecting part, a collision plate and a power supply device; the device body is provided with a hollow cavity, anda sensor mounting surface is located on the side, close to the vehicles, of the device body; the guardrail is detachably connected with the side, away from the sensor mounting surface, of the device body; the controller is installed in the hollow cavity; the vibration sensor is installed on the sensor mounting surface and connected with the controller; the controller is connected with a warning light installed on the top of the device body; the elastic connecting part is arranged in the collision direction of the vehicles, and one end of the elastic connecting part is connected with the devicebody; the power supply device supplies power to the vibration sensor, the controller and the warning lamp; and the controller is in wireless communication with a monitoring center. When vehicles collide the guardrail collision device, the guardrail collision device can conduct warning or remote alarm, the risk of serial traffic accidents is reduced, and more rescue time is acquired.

Description

Technical field [0001] The invention relates to the technical field of highway protection, and more specifically to an intelligent highway guardrail collision device and a control method thereof. Background technique [0002] With the rapid development of my country's economy, the construction of high-speed pipe networks has become more and more perfect, which greatly shortens the distance between cities and cities, and brings great convenience to people's travel and cargo transportation. [0003] However, due to the fast driving speed of vehicles on highways, especially vehicles that are driving fast at night, they are likely to hit the barrier due to driver fatigue or unexpected events. The existing barriers are generally wave barriers or wire rope barriers. When a vehicle collides, When there is an accident, it can be deformed to reduce the damage to vehicles and personnel; but when there are more vehicles, it will cause traffic congestion or serial accidents; in the road with f...

Problems solved by technology

[0003] However, due to the fast driving speed of vehicles on the expressway, especially at night, the fast-moving vehicles are easy to hit the guardrail due to driver fatigue or emergencies. The existing guardrails are generally wave-shaped guardrails or wire rope guardrails. When there are many road sections, it can be deformed to reduce the damage to vehicles and personnel; but when there are many road sections, it will cause traffic jams or serial accidents; once an accident occurs on a road section with few vehicles, it is not easy to be discovered, and it is easy to cause serial collisions of subsequent vehicles. , resulting in severe casualties
