Control device

Abstract

The invention discloses a control device. The control device is composed of a receiving part and an execution part, wherein the receiving part is connected with the execution part. The receiving partis provided with a first signal receiving end, a second signal receiving end, a third signal receiving end and a fourth signal receiving end which are electrically connected with a setter, a height detector, a distance detector and a ground distance detector separately. A first signal transmission end and a second signal transmission end of the execution part are electrically connected with a lifter, and a third signal transmission end of the execution part is electrically connected with a display screen. The setter is used for the general setting of the execution part, within the set height,whether the highest point of a vehicle is within the set maximum value or not is detected, if so, a control device shows safe passage, if not, the control device shows the indication of detour if theheight exceeds the limit, if an over-high vehicle still moves forward blindly and reaches the set distance, a railing is about to move downwards so as to protect the road safety in a bridge or a set channel.

Description

technical field [0001] The invention relates to a control method for road height limit traffic. Background technique [0002] With the acceleration of our urban construction, there are more and more overpasses and tunnels in urban areas, but the traffic protection measures in urban roads are far from meeting the requirements. For example, bridges and tunnel entrances are often hit by super-high vehicles. In order to prevent damage to bridges and tunnels when super-high vehicles pass through, a height-limiting device of equal height is made according to the clearance height of the above-mentioned building facilities. However, because many drivers do not know the specific height of the vehicle they are driving or have a fluke mentality, they will drive forward when they see the height limit sign, causing unnecessary traffic accidents. [0003] The Chinese patent with the publication number CN202362935U discloses an active solar height limit alarm device. The above solution so...

However, because many drivers do not know the specific height of the vehicle they are driving or have a fluke mentality, they will drive forward when they see the height limit sign, causing unnecessary traffic accidents

[0003] The Chinese patent with the publication number CN202362935U discloses an active solar height limit alarm device. The above solution solves the problem that the driver does not know the specific height of the vehicle he is driving or has a fluke mentality. He continues to drive when he sees the height limit sign. The problem of causing unnecessary traffic accidents, but because the structure of the height limiting device is fixed, it will cause a great "obstacle" when special vehicles need to pass through during certain periods

For example, in some road sections, it is necessary to restrict the passage of super-high vehicles, but also to ensure the passage of buses and fire engines. This kind of fixed height limit can no longer meet the requirements.
