Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance / exit management apparatus, and more particularly to an entrance / exit management apparatus for a managed area which is configured using one ID receiver.

[0002]

2. Description of the Related Art A conventional example of an entrance / exit management system for controlling access to a parking lot, a building, a factory or other areas to be managed from a distant place is to determine whether an object has entered or exited the location. For distinction, an ID receiver is provided for each entry and exit. No particular problem arises when these two ID receivers are installed separately from each other or in opposite directions at the entrance and the exit. However, if the installation place of the ID receiver is narrow and it is installed close to each other, it will affect each other, or if it becomes impossible to install it in the opposite direction to the entrance and the exit, both the entering and leaving objects will be both. In some cases, it is not possible to determine whether an object has entered or exited due to access to the ID receiver.

[0003] That is, if the ID transmitter transmits radio waves or transmits magnetic flux, the ID of the entrance is determined.
In the case of an open area where the receiving area of the receiver and the exiting ID receiver cannot be shielded from each other, both the entrance ID receiver and the exiting ID receiver access the object, and it is entry or exit. I can't judge. If the ID transmitter emits light, the entry ID receiver and exit ID placed through the transparent glass
Both receivers cannot receive radiation and cannot distinguish between entry and exit.

In some cases, the entry ID receiver and the exit ID receiver may be installed integrally, but in this case, the overall size becomes large and a large installation space is required, so that various restrictions are imposed. A large amount of cost is required to install the installation place so that the ID receivers do not affect each other. When an entrance ID receiver and an exit ID receiver are provided, the cost of the ID receiver is naturally twice that of a single ID receiver, and the installation work cost is also two.
Double.

Receives the ID number and other individual recognition data transmitted from the ID transmitter 1 and sends the individual recognition data to the entry / exit processing unit 33 of the management computer 3.

The entry / exit processing section 33 inquires whether or not the individual recognition data received in the individual recognition data memory section 34 is stored. The time is stored in the individual recognition data memory unit 34 together with the time. The controller unit 35 receives the entry determination result, the individual recognition data, and the time at the time of entry, stores them in the management data memory unit 37, and issues a command to the gate control unit 36 to release the gate. By outputting, the gate is released and the vehicle can enter the parking lot.

Next, a case where the vehicle is about to leave the parking lot will be described. When exiting, the entry / exit processing unit 33
Inquires whether the individual recognition data is stored in the individual recognition data memory unit 34, and if it is stored, calculates the difference between the time supplied from the clock unit 31 at that time and the time at the time of entry, and For example, if the time required for entry is 5 minutes, if 5 minutes or more have elapsed, it is determined to be exiting, and the individual recognition data, the time at exit and time data of the difference therebetween are transmitted to the controller unit 35. That is, if admission is accepted within a certain period of time, it will not be accepted even if the same ID transmitter is accidentally accessed several times.

The controller 35 receives the exit decision and stores the individual recognition data and the data at the time of exit and the time difference between them in the management data memory 37. here,
When a command to release the gate is output to the gate control unit 36, the gate is released and the vehicle can exit from the parking lot. The controller unit 35 stores the individual recognition data, the time at the time of entry and exit, and the time of the difference as the entry and exit history in the management data memory unit 37,
Use these for management. Then, even when leaving, even if the same ID transmitter is accessed several times within a certain period of time, it will not be accepted. In this way, entry or exit is determined only after a certain time has elapsed, and the accuracy of the determination is ensured. The same processing is performed for the individual recognition data of the other ID transmitters to manage the vehicle.

The emergency processing section 32 transmits a signal for manually opening the gate when the player wants to leave within the above-mentioned fixed time, which is a reference for judging entry and exit. In addition, the entrance sensor 4 and the exit sensor 5 are used to ensure the entrance / exit recognition judgment. The entrance sensor 4 and the exit sensor 5
Detects that the vehicle passes through the gate, and sends a detection signal to the ID receiver 2. When receiving the individual recognition data of the ID transmitter 1, the ID receiver 2 transmits both the detection signal and the individual recognition data to the entry / exit processing unit 33, and determines entry / exit. Thereafter, the same series of operations as those described above are performed.

Another embodiment of the present invention will be described with reference to FIGS. This embodiment further includes two or more entrance detection sensors, an entrance detection first sensor 30 and an entrance detection second sensor 40 as entrance detection sensors,
It includes two or more exit detection sensors, an exit detection first sensor 50 and an exit detection second sensor 60 as exit detection sensors, and also has a warning display 9.

I have. The exit detection first sensor 50 and the exit detection second sensor 60 are provided as exit sensors at a distance from each other in front of the gate unit 8 in the parking lot where vehicles can be detected one by one.

The clock section 31 of the management computer 3 is used to measure the date and time when the vehicle enters and exits, the passing speed, and the vehicle length measurement data. The entry / exit processing unit 33 performs time calculation, vehicle length and speed calculation, various judgment management, data recording, and abnormal dynamics extraction processing in comparison with the parking lot use history of the vehicle.
The individual recognition data memory unit 34 stores the registration data and the processing data of the entry / exit processing unit 33. The controller unit 35 controls a gate control unit 36 that controls the gate unit 8 and the warning display 9. The warning display 9 is installed in the gate unit 8 and displays a message in addition to displaying a warning.

The user first makes a parking lot use contract.
In this case, the vehicle length is known by applying for the vehicle type, and the vehicle length is stored in the individual recognition data memory unit 34 in advance. Then, the ID tag is passed to the user,
The D number is also stored in the individual recognition data memory unit 34. When the user drives the vehicle and enters the gate section 8 from outside the parking lot, the user first passes through the first entrance detection sensor 30 and then stops on the second entrance detection sensor 40. At this time, the entrance detection first sensor 30 detects the passage of the vehicle and outputs a signal of the entrance detection sensor shown in FIG. The output signal is input to the entry / exit processing unit 33 via the ID receiver 2. The input data is recorded in the individual recognition data memory unit 34 and used as data for calculating the vehicle entry speed Sm and the vehicle length ML. This calculation result is also recorded in the individual recognition data memory unit 34. FIG. 6 is a diagram illustrating another signal output of the entrance detection sensor.

Vehicle entry speed Sm = sensor installation interval: LS
× Conversion coefficient k / Vehicle traveling time: Tm Vehicle length ML = Vehicle detection time: Ts × Vehicle approach speed Sm ×
Conversion coefficient k The calculated vehicle length ML is compared with the vehicle length previously recorded and registered in the individual recognition data memory unit 34 to determine whether or not the vehicle type is a legitimate vehicle type. The entry or exit is determined by determining the order in which the vehicle moves and passes through the entrance detection first sensor 30, the entrance detection second sensor 40, the exit detection first sensor 50, and the exit detection second sensor 60. You can decide whether to enter or leave. This determination is also performed in the entry / exit processing unit 33, and entry / exit is also stored in the individual recognition data memory unit 34.

Next, the ID number transmitted from the user via the ID transmitter 1 is received by the receiver 2, and the entry / exit processing unit 33
To determine whether the user is a contractor. In this case, it is determined that the vehicle is a legitimate vehicle by the detection and is used as the determination data of the entry / exit processing unit 33, and the gate unit 8 is opened via the controller unit 35 and the gate control unit 36. In the case of leaving, the same operation control as described above is performed.

The entry and exit data recorded as described above are combined as a pair to prevent the same vehicle from passing through the gate section 8 again in a short time, so that entry can be continued. Block. The same applies to the case of leaving. By accumulating the above data, the average passing time from the entrance detection first sensor 30 to the exit detection second sensor 60 at the time of entrance / exit is calculated, and it is compared with this time every time to determine whether or not it is abnormally long. To check. Also, the time from the entrance detection first sensor 30 to the entrance detection second sensor 40 and the exit detection first sensor 50 to the exit detection second sensor 6
By comparing the time to 0 and checking whether the time is abnormally long, the dynamics of each vehicle are grasped to detect fraud. The detected abnormality or fraud is displayed on the warning display 9 via the controller 35 as a caution message or warning.

In the above other embodiment, even if it is not possible to close the gate immediately upon detection of fraud, it is possible to prevent fraud by issuing a warning. When the object is a vehicle, the vehicle length can be recognized by registering the vehicle type at the time of contract, and the length of the vehicle passing through the gate can be measured to determine whether or not the vehicle type is registered. .

By passing the two detection sensors, the passing speed and the object length are measured from the passing time and the installation distance of the sensors, and the measurement results can be used for various controls. The entry or exit can be determined by determining the order in which the objects pass through the detection sensor. By authenticating the ID transmitted from the ID tag only when the vehicle is detected by the detection sensor, it is possible to prevent passage of vehicles other than the registered vehicle.

Authentication of the ID transmitted from the ID tag is recorded, and entry and exit can be managed by combining entry and exit of the same ID, that is, the same vehicle. The time passing through each detection sensor, the speed, and the time from opening to closing of the gate are recorded, and an abnormally long passing time can be checked by comparing with the normal passing time.

The entrance and exit can be managed by preventing the same vehicle from passing through the gate again within a short time. By recording data relating to entrance and exit and using the data as a history, the dynamics of the object can be grasped, and the dynamics at the time of abnormality can be obtained from the dynamics at the normal time. It is possible to prevent fraud by judging fraud from the dynamics at the time of abnormality and displaying a warning.

By checking the following vehicle based on the detection data of the plurality of entrance detection sensors and the detection data of the plurality of exit detection sensors, it is possible to detect the continuous entrance and exit of many vehicles. Furthermore, by managing entrance and exit based on the detection data of the entrance detection sensor and the detection data of the exit detection sensor and the registered individual recognition data,
Vehicle and human entry / exit can be identified.

[0035]

As described above, according to the present invention, two ID receivers for entry and exit are simultaneously received and cannot be determined, and the number of ID receivers is one, so that the determination can be reliably performed. Then, the number of the ID receiver becomes one, and the cost of the ID receiver and the construction cost for installing the ID receiver are reduced, so that the entrance / exit management device can be configured at low cost. In addition, since only one ID receiver is required, the ID receiver can be made compact and the installation space can be reduced. Further, since there is no need to perform shielding for simultaneous reception, no construction cost is required. In addition, it can be installed anywhere, increasing the degree of freedom in design.
