Description

Vehicle control system using Zigbee communication and height measurement

The present invention can prevent damage to vehicles and structures by promptly warning in advance through a Zigbee communication for vehicles exceeding a limited height before vehicles pass through various types of structures such as viaducts, tunnels, piers, overpasses, underpasses, etc. Vehicle control system using Zigbee communication and height measurement.

Due to the recent increase in the three-dimensionality of roads, the installation of various structures such as viaducts, tunnels, piers, overpasses, and underpasses has increased on roads driven by automobiles, and facilities crossing roads have increased with the increase in electrical and communication facilities. Doing.

Since structures with height limits are marked with height restrictions according to road traffic regulations, the driver of the vehicle compares the height of the vehicle with the height displayed on the structure and decides whether to pass.

However, in this case, unless the driver accurately grasps the road conditions, there is always a risk of an accident and there is a possibility of developing into a large accident and traffic paralysis in the event of an accident on an elevated highway.

When a vehicle exceeding the limit height enters the structure due to a judgment error, the upper part of the vehicle collides with the structure, causing damage to the structure as well as the vehicle.

In particular, there is a problem in that a large accident may be caused when the structure is a pedestrian or a pier with frequent human traffic.

In order to solve this problem, a vehicle passing height limit warning device has been proposed in which an obstacle detection sensor is installed in the front upper part of the vehicle to detect the passing height to detect whether the vehicle has passed, but problems in use and application have appeared.

First, most vehicles exceeding the height limit have a much higher height than the front part of the vehicle, so even if the obstacle sensor does not detect the structure, the load and the structure loaded on the back of the vehicle will collide. There is a probability that can.

Second, there is a problem in that the response time after recognition is too short when the vehicle cannot pass due to the height limitation of the structure located in front of the vehicle while driving on the highway or a road capable of high-speed driving.

Therefore, the underpass vehicle control system of road facilities using Zigbee communication and height measurement sensor to prevent damage to the vehicle and road structures by warning in advance about the vehicle exceeding the limit height before the vehicle passes through the structure is developed. I want to.
