Although described, the present invention is not necessarily limited thereto,

In general, when many vehicles enter at the same time or a plurality of vehicles enter in succession due to lack of remaining parking space, the vehicle flow is stagnant and the distance between each vehicle becomes very narrow or close to each other. can enter

Therefore, through the analysis of images captured by the first and second recognition modules 31 and 32 provided as cameras, the passing state of the vehicle cannot be accurately recognized, and misrecognition of the vehicle may occur.

When the blocking bar 41 malfunctions due to such a misrecognition of the vehicle, a delay in vehicle traffic occurs due to the blocking of the vehicle's access passage, or the blocking bar 41 rotates and applies an impact to a passing vehicle to block the vehicle Safety accidents such as breakage or damage of the bar 41 may occur.

In order to solve this problem, the present invention may further include an additional recognition module for auxiliary recognition of the passing state of the vehicle in the recognition unit 30 .

So, the proximity detection sensor detects a vehicle or object passing through the lower portion of the blocking bar 41 during rotation of the blocking bar 41, and the detection signal output from the proximity detection sensor is transmitted to the control unit 50.

Then, the control unit 50 determines whether or not the vehicle passes according to the detection signal, and if it is determined that the vehicle is passing, the controller 50 rotates the blocking bar 41, which is rotating downward, upward again to close the entry passage. An interrupt signal may be generated to open the entry passage.

As such, the present invention adds a third recognition module to the blocking bar to accurately detect whether or not the vehicle has passed, thereby preventing misrecognition that may occur in the case of continuous entry of the vehicle, thereby preventing damage or damage to the vehicle and the blocking bar. accidents can be prevented.
