The single-side sensing module is arranged at an inlet and an outlet of the parking lot, is used for sensing a sensing signal Y1 when a vehicle enters the parking lot and a sensing signal Y2 when the vehicle leaves the parking lot, and transmits a detection signal to the control center; the single-sided sensing module adopts one or a combination of grating or infrared detection, but is not limited to the two single-sided detection.
When the vehicle enters, the control center compares the received on-off signal X1 with the sensing signal Y1, specifically: the control center matches the received on-off signal X1 with the induction signal Y1, and when the on-off signal X1 appears once and the induction signal Y1 appears once or more times, namely the remaining parking spaces of the parking lot are updated by subtracting 1 through the analysis module when the vehicle passes through; when the on-off signal X1 does not appear and the sensing signal Y1 only appears n times, namely the remaining parking spaces of the parking lot are updated and n is subtracted by the analysis module when the vehicle passes through; when the on-off signal X1 appears for multiple times and the sensing signal Y1 does not appear, namely the vehicle passes through, the remaining parking space of the parking lot is updated to be reduced by 1 through the analysis module.
When the vehicle leaves, the control center compares the on-off signal X2 with the sensing signal Y2, specifically: the control center matches the received on-off signal X2 with the induction signal Y2, and when the on-off signal X2 appears once and the induction signal Y2 appears once or more times, namely, the remaining parking spaces of the parking lot are updated and increased by 1 through the analysis module when the vehicle passes through; when the on-off signal X2 does not appear and the sensing signal Y2 only appears n times, namely the remaining parking spaces of the parking lot are updated and increased by n through the analysis module when the vehicle passes through; when the on-off signal X2 appears for multiple times and the sensing signal Y2 does not appear, namely the vehicle passes through, the remaining parking space of the parking lot is updated and increased by 1 through the analysis module.
The position of the single-side sensing module is additionally provided with a video shooting module, front and back 1-3s videos switched on and off by the sensing signal Y1 and the sensing signal Y2 are shot and recorded through the video shooting module, and the recorded video signals are stored in storage equipment through a control center for backup.
As shown in fig. 2, the method for improving the system for monitoring the remaining parking space accuracy includes the following steps:
s1, firstly, the vehicle drives into an entrance position where the parking lot is located, and enters an area sensed by the anti-smashing sensing module where the entrance position is located, and when the anti-smashing sensing module senses that the vehicle passes through, an on-off signal X1 is generated;
s2, when the vehicle enters the area sensed by the single-side sensing module, the single-side sensing module senses that the vehicle passes by and generates a sensing signal Y1;
s3, the control center receives the on-off signal X1 and the induction signal Y1 at the same time, the on-off signal X1 and the induction signal Y1 are analyzed through the analysis module, and then an instruction is given to display the number of the remaining parking spaces in the parking lot in real time to update and decrement the number; during specific operation, when the vehicle normally runs, the on-off signal X1 generated by the anti-smashing induction module is on or off once, but due to different conditions of the vehicle, such as a semi-trailer van, the transversely received induction signal Y1 may exist once or for multiple times, and when the control center receives the two signals simultaneously, the control center only gives an instruction to display that the number of the remaining parking spaces in the parking lot is reduced by 1 in real time.
When the on-off signal X1 does not appear (for two vehicles or a plurality of vehicles which are close to each other and drive in simultaneously, the smash-proof sensing module cannot be triggered to sense the on-off signal, namely, the interval distance is too short), and the single-side sensing module can generate one or more times of on-off signal Y1, the control center gives an instruction to display the number of the remaining parking spaces in the parking lot in real time to reduce N (N is the total number of the vehicles passing through).
When the on-off signal X1 appears once or many times (namely, when the multi-axle truck runs, the middle connecting shaft is adopted to realize multi-section connection, but the middle connecting shaft influences the judgment of the on-off signal X1, the on-off condition can appear many times, and the situation that the residual parking space is judged by directly adopting the on-off signal X1 is obviously unreasonable), and at the moment, the single-side sensing module can only generate one-time sensing signal Y1 to be switched on and switched off, and then the command is given by the control center to display that the number of the residual parking spaces in the parking lot is reduced by 1 in real time.
And S4, enabling the vehicle to run out of the exit position of the parking lot and enter the area sensed by the anti-smashing sensing module at the exit position, and generating an on-off signal X2 when the anti-smashing sensing module senses that the vehicle passes through.
And S5, the vehicle enters the area sensed by the single-sided sensing module at the exit position, and when the single-sided sensing module senses that the vehicle passes through, a sensing signal Y2 is generated.
S6, the control center receives the on-off signal X2 and the induction signal Y2 at the same time, the on-off signal X2 and the induction signal Y2 are analyzed through the analysis module, and then an instruction is given to display the number of the remaining parking spaces in the parking lot in real time to update and increase the number of the remaining parking spaces; the condition that the vehicle enters the parking lot can be displayed in real time.
Above-mentioned scheme can provide the accurate judgement (only adopt two kinds of collection data to judge, can reduce control center's operand, reduces the corresponding time of equipment promptly) when the parking area surplus parking stall statistics calculates, has greatly saved the human cost and has gone to correct the surplus parking stall, or has leaded to because of correcting untimely, the emergence of the situation such as the vehicle is exploded often appearing in the parking area.
