Description
Technical Field
The invention relates to the field of overload prevention and relief systems, in particular to an entrance overload prevention and relief system for a highway and a working method thereof.
Background
In order to ensure that vehicles run safely on the highway, reduce the probability of highway traffic accidents, ensure that the highway pavement is not easy to damage and reduce the possibility that the overrun vehicles run on the highway, the overrun vehicles generally mean that any one or more conditions of overlength, overwidth, superelevation and overweight exist at the same time, however, as the highway unit does not have the authority, only an overrun refuge system can be installed at the entrance of the highway, and the overrun vehicles cannot feel at the high speed by adopting the modes of refuge and dissuasion, and only the legal overrun transport vehicles submit applications to relevant departments and can run the highway after approval by the manager.
The specific working conditions of the existing overload relieving system are as follows: when a vehicle enters a coil in a lane, the coil sends a vehicle entering signal to a license plate recognition instrument, the license plate recognition instrument automatically captures to obtain a license plate number and sends the license plate number to an industrial control computer, then the vehicle sequentially enters the coil and a weighing sensor, the weighing sensor collects information of each axle weight and sends the information to the weighing instrument, meanwhile, the vehicle completely passes through a grating and then sends a grating ending signal to the weighing instrument, the weighing instrument receives the ending signal and then automatically calculates to obtain a total weight by combining with each received axle load information, then the total weight information is sent to the industrial control computer, a management system running in the industrial control computer automatically stores related information into a database after receiving the license plate information and the total weight information, and calculates to obtain whether the vehicle is over-limited or not according to an over-limit standard, and simultaneously displays information whether the vehicle can enter a toll station or not to an LED display screen, if a driver cannot enter the toll station according to the information prompted by the LED display screen, if the vehicle is out of limit, a sound alarm can remind the worker, the railing can automatically fall down, and the worker needs to guide the vehicle to return to the original path.
However, when there are many vehicles needing to return to the lane where the vehicles are located and the vehicles are arranged in a long queue, the original way of reversing and returning is easy to cause traffic jam, and for some vehicles which do not return or return according to a specific route by using a hard intrusion barrier machine, the existing system cannot effectively supervise the vehicles and strictly process the next entry of the vehicles.
Disclosure of Invention
1. Technical problem to be solved
The invention aims to provide an entrance overload prevention system for an expressway and a working method thereof, which can realize that a road for returning an overload vehicle is provided by arranging an exit lane, so that the entrance overload vehicle is not easy to block other vehicles from entering the expressway, two entrance lanes share one exit lane, the occupied space of the exit lane is reduced, the return route of the overload vehicle is controlled by a plurality of groups of railings, the exit speed of the overload vehicle is improved, the entrance of the expressway is not easy to cause traffic jam, the return condition of the vehicle is monitored by arranging gratings on two sides of the exit lane, and a blacklist is added to the vehicles which do not return or return according to a specific route, so that the next passing of the vehicles is strictly treated.
2. Technical scheme
In order to solve the above problems, the present invention adopts the following technical solutions.
An entrance overload prevention and return system for a highway comprises an industrial control computer, lane groups and a railing unit, wherein the lane groups comprise a lane, an upper lane and a lower lane which are arranged on two sides of the lane, weighing instruments are arranged on the upper lane and the lower lane, the railing unit comprises an upper railing unit, a lower railing unit and a main railing unit, the upper railing unit is arranged in the upper lane, the lower railing unit is arranged in the lower lane, the way for returning an overrun vehicle is provided by arranging the lane, so that other vehicles are not easy to be blocked from entering the highway, the two lanes share one lane, the space occupied by the lane is reduced, the return route of the overrun vehicle is controlled by a plurality of groups of railers, the exit speed of the overrun vehicle is improved, the entrance of the highway is not easy to cause traffic jam, and gratings are arranged on two sides of the lane, and monitoring the vehicle return condition, and adding the vehicles which are not returned or are not returned according to a specific route into a blacklist so as to strictly process the next passing of the vehicles.
Further, the weighing instrument includes two weighing sensors, and two weighing sensors are located the left and right sides in lane respectively, the average value of two weighing sensors is got to the weighing result, improves the rate of accuracy that the vehicle weighed, effectively guarantees the accuracy that the vehicle weighed to make the weight of vehicle be difficult for receiving the influence of ground flatness and vehicle vibrations itself.
