BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view of a gate-type parking lot to which a parking lot management device having a blocking bar abnormality detection function according to the present invention is applied.
[0017]
The gate-type parking lot 1 of FIG. 1 has a parking ticket issuing machine 2, an entrance gate device 3 for regulating the traffic of the entering vehicle, and a vehicle passing direction in the ground in a passage portion where the vehicle passes, on the entrance side. And a vehicle detection sensor 4 including a pair of loop coils 4A and 4B embedded along the vehicle.
[0018]
The parking ticket issuing machine 2 issues a parking ticket in which, for example, guidance is provided and the entrance time is recorded by input of the vehicle detection output from the loop coil 4A, and when the parking ticket is removed, the blocking bar 3B is provided to the entrance gate device 3. Output the open command signal. Further, after the vehicle detection output is input from the loop coil 4B, if the vehicle detection output sequentially disappears in the order of the loop coils 4A and 4B, it is determined that the vehicle enters the vehicle when the vehicle detection output of the loop coil 4B disappears, and the entrance gate is determined. A closing command signal for the shut-off bar 3B is output to the device 3.
[0019]
The entrance gate device 3 includes a device main body 3A and a blocking bar 3B, and the device main body 3A includes a control unit and a driving unit that opens and closes the blocking bar 3B. The control unit of the apparatus main body 3A controls the drive unit to open the shut-off bar 3B by input of the shut-off bar open command signal from the parking ticket issuing machine 2, and closes the shut-off bar 3B by input of the shut-off bar close command signal. Control the drive unit to drive.
[0020]
On the other hand, on the exit side of the parking lot 1, a toll settlement machine 5, an entry gate device 6 for regulating the traffic of the participating vehicles, and a vehicle buried along the vehicle traffic direction in the ground of a passage through which the vehicles pass. And a vehicle detection sensor 7 including a pair of loop coils 7A and 7B. Here, on the exit side of the parking lot, the loop coil 7A is located in the parking lot 1 and corresponds to a first loop coil with a cut-off bar 6B described later, and the loop coil 7B is in the vicinity of the cut-off bar, for example, the cut-off bar 6B. And corresponds to a second loop coil.
[0021]
As shown in FIG. 2, the fare adjustment machine 5 includes a control unit 11 and a memory 12 as a recording unit for recording the number of illegally passing vehicles as described later. Based on the vehicle detection output from the loop coil 7A, the control unit 11 performs, for example, guidance for prompting payment of the fee, and calculates the parking time calculated based on the entry time data of the inserted parking ticket and the current time. The parking fee is calculated, and the payment process is performed by inputting money. Upon completion of the settlement, a shutoff bar open command signal is output to the entry gate device 6. Further, after outputting the cut-off bar opening command signal upon completion of settlement, as shown in FIG. 3A, a vehicle detection output is generated (ON) from the loop coil 7B, and thereafter, the loop coils 7A and 7B are arranged in this order. When the vehicle detection output sequentially disappears (OFF), when the vehicle detection output of the loop coil 7B disappears, it is determined that the vehicle has entered, and a closing command signal for the shut-off bar 6B is output to the entrance gate device 6. Further, the control unit 11 receives the vehicle detection output from the loop coil 7B in a state where the shut-off bar opening command signal is not generated, and thereafter generates a shut-off bar opening command signal when the vehicle detection output disappears. It is determined that the vehicle has participated in spite of the absence, and when the vehicle detection output of the loop coil 7B disappears as shown in FIG. For example, the information is output to an alarm device 8 provided as a reporting means provided at a management office where a manager is resident. Therefore, the control unit 11 of the fare adjustment machine 5 has a function of a blocking bar abnormality determination unit. In the present embodiment, the fare adjustment machine 5 corresponds to a parking lot management device having a shutdown bar abnormality detection function. Further, by counting the number of occurrences of the abnormality determination output and storing the counted number in the memory 12, the number of vehicles that have illegally left the parking lot while the shut-off bar 6B is abnormal is stored in the memory 12.
[0022]
The entry gate device 6 includes a device main body 6A and a blocking bar 6B. As illustrated in FIG. 2, the device main body 6A includes a control unit 13 and a driving unit 14 that opens and closes the blocking bar 6B. The control unit 13 controls the driving unit 14 to open and close the shut-off bar 6B in response to the input of the shut-off bar open command signal from the fare adjustment machine 5, and to close and drive the shut-off bar 6B in response to the input of the shut-off bar close command signal. Controls the drive unit 14.
[0023]
Note that the control unit 11 may be configured to be connectable to a network system of a management company that manages the parking lot 1 so that the abnormality determination output of the control unit 11 can be transmitted to the management company via the network. .
[0024]
Next, the operation of the control unit 11 of the fee settlement machine 5 will be described with reference to the flowchart of FIG.
In step 1 (indicated by S1 in the figure, the same applies hereinafter), it is determined whether or not a shut-off bar opening command signal has been generated. If so, the process proceeds to step 2, and if not, the process proceeds to step 6 described later. move on.
[0025]
In step 2, it is determined whether or not both loop coils 7A and 7B are ON. If both are ON, it is determined in step 3 whether or not loop coil 7A is OFF. It is determined whether or not it has been turned off. Then, when the loop coil 7B is turned off, it is determined that the vehicle has entered, and the process proceeds to step 5, where a closing command signal for the shut-off bar 6B is generated.
[0026]
On the other hand, if the determination in step 1 is NO and the shut-off bar open command is not issued, that is, if the shut-off bar 6B is controlled to be closed, it is determined in step 6 whether the loop coil 7B is turned on. Then, in step 7, it is determined whether or not the loop coil 7B has been turned off. If the loop coil 7B has been turned off, the vehicle can enter even though the shut-off bar 6B is being closed. In step 8, it is determined that the shipment is illegal, and the interruption bar abnormality determination output is sent to the management center via the alarm device 8 or on-line via the network to notify the administrator of the occurrence of the abnormality. Further, each time an abnormality determination output is generated, the abnormality determination output is counted, and the count value is stored in the memory 12 as the number of illegally dispatched vehicles.
[0027]
The normal delivery process for a vehicle for which the fare has been settled is the same as the conventional one. Briefly, when a vehicle is detected by the loop coil 7A, the fare adjuster 5 waits for a parking ticket to be inserted, and the parking ticket is inserted. Then, the parking time is calculated by calculating the parking time, and the toll settlement process is executed by inputting money or the like. When the settlement is completed, a shutoff bar opening command is output to the entry gate device 6. Thereby, the control unit 13 of the entry gate device 6 controls the drive unit 14 to open and drive the blocking bar 6B. Thereafter, the control unit 11 monitors the output change state of the loop coils 7A and 7B as shown in steps 2 to 4 described above, detects the entry of the vehicle, and drives the blocking bar 6B to close.
[0028]
According to this configuration, the abnormality of the shut-off bar 6B can be detected by using the vehicle detection sensor 7 and the control unit 11 of the fare settlement machine 5 which are the existing facilities. There is no need to provide a new one. In addition, there is an advantage that the number of vehicles that have been illegally retrieved can be managed. In addition, by immediately reporting the abnormality of the blocking bar 6B to an administrator or the like, it is possible to quickly prevent illegal parking of the parked vehicle and repair the blocking bar 6B.
[0029]
When the control unit of the parking ticket issuing machine 2 at the entrance of the parking lot is also provided with a blocking bar abnormality detecting function, the blocking bar 3B, for example, the blocking bar 3B may be closed in a state where the opening command of the blocking bar is not issued. After the vehicle detection output is generated from the loop coil 4B buried across the inside and outside of the parking lot at the boundary, the interruption bar abnormality may be determined when the vehicle detection output disappears.
[0030]
In the above embodiment, the case where two loop coils are installed at the parking lot exit has been described. However, as shown in FIG. 5, three loop coils 7A to 7C may be installed at the parking lot exit. In the figure, the same elements as those of the embodiment shown in FIG. 1 are denoted by the same reference numerals. Here, the loop coil 7A corresponds to a first loop coil, the loop coil 7B corresponds to a second loop coil, and the loop coil 7C corresponds to a third loop coil.
[0031]
In this case, as shown in FIG. 6, similarly to the case where two loop coils are installed, in a state where the open command signal of the interrupting bar 6B is not generated, the vicinity of the interrupting bar 6B, for example, the interrupting bar 6B is moved. Based on the vehicle detection output of the loop coil 7B straddling the inside and outside of the parking lot at the boundary, when the loop coil 7B is turned on and then turned off, it is determined that there is an unauthorized leaving vehicle, and the blocking bar 6B is determined to be abnormal, and the abnormality is determined. Generate output.
[0032]
In a normal delivery process for a vehicle for which the fare has been settled when the shut-off bar is normal, the three loop coils 7A to 7C change in a state as shown in FIG. 6 (the outputs of the loop coils 7A and 7C are indicated by broken lines). Then, when the vehicle detection output of the loop coil 7C disappears, a shutoff bar closing command signal is generated.
[0033]
Further, there is a case where only one loop coil is provided as a vehicle detection sensor in the vicinity of the blocking bar. Needless to say, in this case, the vehicle detection output is generated from the loop coil in a state where the opening command of the blocking bar is not generated. Thereafter, when the vehicle detection output disappears, it is determined that the blocking bar is abnormal.
[0034]
Further, the present invention is not limited to a parking lot using a loop coil as a vehicle detection sensor, but is applicable to any parking lot using a sensor such as an optical sensor that detects passage of a vehicle from a state of output change.
[0035]
In the above-described embodiment, the control unit of the parking lot management device such as a fare settlement machine or a parking ticket issuance device is provided with the blocking bar abnormality detection function. However, the control of the existing vehicle detection sensor and the parking lot management device is performed. A blocking bar abnormality detecting unit as a blocking bar abnormality detecting device having a function of connecting to a vehicle detection sensor and an output signal of a control unit and detecting an abnormality of the blocking bar. It may be configured to be attachable to the management device, and the detection unit may be incorporated into the parking lot management device to detect an abnormality of the blocking bar.
[0036]
【The invention's effect】
As described above, according to the parking lot management device and the interruption bar abnormality detection device having the interruption bar abnormality detection function of the present invention, the abnormality of the interruption bar can be detected using the existing equipment, so that the interruption is newly performed. There is no need to provide components dedicated to bar abnormality detection. In addition, there is no need to consider a space for installing a component dedicated to abnormality detection. In addition, it is possible to monitor the abnormal leaving of the vehicle together with the detection of the abnormality of the blocking bar, and there is an advantage that the number of illegally leaving vehicles can be managed.
