Barrier gate opening counting method

Abstract

The invention discloses a barrier gate opening counting method, which can automatically eliminate the abnormal state of a gate rod and restore the gate rod to a normal state by detecting the state ofthe gate rod when a vehicle is out of a gate and executing a mode of not increasing the gate opening times of the gate rod after confirming that the gate rod is in an abnormal state, thereby solving the problems in the prior art. The method comprises the steps that S1, when a barrier gate receives a gate opening instruction, the state of a gate rod is detected, the step S2 is executed when the gate rod is in a gate opening state, and the step S4 is executed when the gate rod is in a gate closing state; s2, whether a vehicle exists below the brake bar or not is detected, if yes, the step S4 isexecuted, and if not, the step S3 is executed; s3, the operation of adding 1 is not executed into the gate opening frequency and the step S5 is executed; s4, the operation of adding 1 into the gate opening frequency is executed and the step is executed S5; and S5, after it is detected that the vehicle leaves the gate, the operation of subtracting 1 from the gate opening frequency is executed, whether the gate opening frequency is an initial defined value or not is inquired, if yes, the gate rod is closed, and otherwise, the gate rod is kept in an open state.

Description

Technical field [0001] The invention relates to the technical field of road equipment, in particular to a method for counting the opening of a barrier gate. Background technique [0002] Barriers, also known as car stoppers, are access management equipment specially used to restrict motor vehicles on roads. They are widely used in parking lots, business districts or residential areas, and are also widely used in construction machinery testing places. [0003] In the prior art, generally speaking, when a vehicle comes out of a parking lot where a barrier is installed and the barrier detects that the vehicle has entered the exit range, it will detect and identify the vehicle and report it to the parking lot management system. There is a parking lot management system. Decide whether to open the brakes, and after obtaining the permission to open the brakes, count the openings, that is, add 1 to the number of openings, and at the same time the brake lever opens to let the vehicle go out...

AI Technical Summary

Problems solved by technology

However, if there are two or more vehicles closely following the vehicle, an abnormal situation will occur at this time. The following is a specific description of the situation where two vehicles are closely following the vehicle: the barrier gate detects that two vehicles are about to leave When the exit comes out, it can be that when the barrier detects that a vehicle has entered the exit range but has not completely exited the brake lever, another vehicle enters the exit range. At this time, the number of times the brake lever is opened increases by 2, but After the brake, the vehicle at the rear followed the vehicle in front and went out from the brake lever. At this time, the brake lever mistakenly thought that only one vehicle had gone out from the brake lever, so the number of times the brake lever was opened was only reduced by 1, and That is to say, the brake lever will perform an opening operation again, causing the brake lever to be in the open state; when the next car reaches the exit range, it will be found that the brake lever is in the open state, because when the next car enters the exit range, the parking lot The management system continues to notify the gate to open the gate and count, which will cause the gate lever to be in the open state all the time. At this time, for the barrier gate in the prior art, manual reset and other operations can only be performed to make the gate lever open. Return to normal, but the time period before the brake lever returns to normal will seriously affect the operation of the parking lot, such as the possibility of evading fees
