Description

Automatic reminder protection alarm device for vehicles transporting dangerous goods

technical field

The invention relates to a vehicle carrying dangerous goods. During the transportation process, an automatic protection device is used to prevent the front and rear vehicles from following the vehicle too closely, monitor and remind the driver to avoid accidents, and belongs to the technical field of automobile transportation and safety.

Background technique

During the transportation of dangerous goods (dangerous chemicals, military special supplies, and destructive items that are likely to cause combustion, explosion, and flow), especially when driving on the expressway, because the vehicle itself is too close to the vehicle, or the front, rear, left, and right Vehicles are too close to the vehicle, and because other vehicles overtake or are too fast, collisions with vehicles carrying dangerous goods cause accidents, or the accidents are further expanded, and incidents that lead to secondary accidents occur frequently.

If computer technology, sensor technology, and automatic control technology can be fully used to build a safety monitoring and early warning system for dangerous goods transportation during the driving process of dangerous goods vehicles, the system will In the stage of state emergence, if timely and accurate early warning and active control can be given, measures can be taken in time to prevent serious losses and improve the transportation safety of dangerous goods vehicles.

Dangerous goods transportation vehicles are generally under full load or overloaded working conditions, and the external driving environment is complex. In the case of fast transportation, if the distance between vehicles is unreasonable, collision accidents are very likely to occur. The specific performance is as follows: 1) The operating environment is complex and diverse. Dangerous goods transport vehicles are often in the long-distance transportation situation, mainly driving on expressways or related designated roads at night. Highway forms such as bridges, and severe weather such as strong winds, rain, and snow. 2) Braking distance and speed are difficult to evaluate. During the driving process of dangerous goods vehicles, some enterprises will adopt the form of full load to save costs, which makes it difficult for the vehicle to control the speed and braking distance in real time due to the existence of inertia in the process of braking and acceleration and deceleration, and it is very easy for the driver in the long-distance transportation environment. Fatigue occurs, resulting in accidents. 3) How to drive and avoid collisions mainly depends on the experience of individual drivers themselves. During the opposite direction, the same direction or the process of changing lanes, the safety distance needs to be subjectively judged by the driver's experience, which is prone to deviation. Due to the complexity of the operating environment of dangerous goods vehicles, coupled with the influence of factors such as overloading, vehicle speed, and braking distance during long-distance transportation, dangers are prone to occur, and the severity of secondary hazards after the danger occurs, resulting in the collision of dangerous goods vehicles. Active prevention and control requirements are higher and more difficult.
