[Embodiment of device]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings as an example in which the embodiment is applied to a multi-storey parking lot having a total of eight pallets of three rows and three stages.

A. Configuration of Example A-1. Structure of Multistory Parking Lot and Parking Place Identification System FIG. 1 is a conceptual diagram showing the structure of a parking place identification system in a multistory parking lot according to an embodiment of the present invention. FIG. 2 is a conceptual diagram showing the structure of a multi-storey parking lot to which the parking place identification system according to this embodiment is applied. In FIG. 1, the parking place identification system in a multi-storey parking lot is provided with a palette number PN attached to each pallet and an identification code IDc of the transponder 2 provided in the vehicle. Based on the above, the reader 1 issues a warning to prevent the vehicle from being parked in the wrong pallet, and as described above, when the vehicle is placed in the high frequency magnetic field, the reader 1 supplies power by electromagnetic coupling, It is composed of a transponder 2 which operates each unit by electric power and transmits an identification code IDc stored in advance. Detailed configurations of the reader 1 and the transponder 2 will be described later.

Next, in FIG. 2, the multi-storey parking lot is composed of a plurality of pallets P (3 rows × 3 layers) having a vacancy in the uppermost stage of the central portion (a total of 8 pallets). In the following, the respective palettes are designated as P1 to P8 and the vehicles to be parked on the respective pallets are designated as C1 to C8. The illustrated state is an example of an arrangement in one state at a certain point in time, and each pallet P1 to P8 can be moved up and down, left and right by a pallet drive system (not shown). The pallet drive system normally moves the corresponding pallet P to the ground surface based on the personal identification number input from the operation panel provided in the parking lot. In the figure, the pallets P2, P4 and P7 are located on the ground surface, the pallets P3, P5 and P8 are located underground, and the pallets P1 and P6 are located at the top.

The vehicles C2, C4, C7 of the pallets P2, P4, P7 arranged on the ground surface can be delivered as they are. On the other hand, the vehicle C5 of the pallet P5 can leave the pallet P5 by raising the pallets P4 and P5 at the same time to raise the pallet P5 to the ground surface. In addition, the vehicle C1 (C6) of the pallet P1 (P6) raises the pallet P4, traverses the pallet P2 (P7) to the right (left), lowers the pallet P1 (P6) to the ground surface, and then exits. it can. Further, the vehicle C3 (C8) of the pallet P3 (P8) raises the pallet P4, moves the pallet P2 (P7) to the right (left), and raises the pallet P3 (P8) to the ground surface, You can leave the warehouse.

A-2. 1. Block Configuration of Reader Next, returning to FIG. 1, the reader 1 includes an antenna 3a, 3b, 3c, an antenna switch 4, a transmission / reception circuit 5, sensors 6a, 6b, 6c, a pallet number detection circuit 7, an ID code / pallet number. It is composed of an analysis / setting circuit 8, a memory circuit 9, a reproducing circuit 10, a speaker 11 and an interface circuit 12. The antennas 3a, 3b, 3c are arranged at a fixed portion in the center front part of the pallet P (pallets P2, P4, P7 shown in FIG. 2) located on the ground surface of the multi-story parking lot, and are to be described later in the transmission / reception. When the high-frequency current from the receiving circuit 5 flows, a high-frequency magnetic field is generated and the identification code IDc transmitted from the transponder 2 that has entered the high-frequency magnetic field is received. Here, FIG. 3 is a conceptual diagram showing a positional relationship between the side surfaces of the pallets P6, P7, P8 shown in FIG. 2, the reader 1, and an arbitrary vehicle C. In the figure, the arrangement of the antenna 3c and the sensor 6c when the pallet P7 is located on the ground surface is shown. The antenna 3c is provided at a position sufficiently close to generate electromagnetic induction in the transponder 2 (details will be described later) arranged in the rear portion of the vehicle C that is about to enter.

The antenna switch 4 is inserted between the antennas 3 a, 3 b and 3 c and the transmission / reception circuit 5, and under the control of the transmission / reception circuit 5, distributes a high frequency current or a reception signal at predetermined time intervals. The transmission / reception circuit 5 generates a high-frequency magnetic field around the antennas 3a, 3b, 3c by causing a high-frequency current to flow sequentially to the antennas 3a, 3b, 3c via the antenna switch 4 periodically or constantly. , Receives the identification code IDc transmitted by the transponder 2 that automatically responds to the high-frequency magnetic field, and supplies it to the ID code / pallet number analysis / setting circuit 8. The identification code IDc is a code for identifying the transponder 2. For example, in FIG. 2, the pallet numbers PN of the pallets P1 to P8 and the identification codes of the transponders 2 of the vehicles C1 to C8 parked on the pallet number PN. It has the same value as IDc.

Next, the sensors 6a, 6b, 6c correspond to the above-mentioned antennas 3a, 3b, 3c, and a pallet P (pallets P2, P4, P7 shown in FIG. 2) moving to the ground surface of the multistory parking lot. ) Is arranged in the fixed part near the central rear part. The pallet number detecting circuit 7 reads the pallet number PN attached to the pallet P moved to the ground surface by the sensors 6a, 6b, 6c, and analyzes / sets the read pallet number PN to the ID code / pallet number. Supply to the circuit 8. The pallet number PN is attached at a predetermined position on the pallet P by a bar code or a magnetic pattern, and the sensors 6a, 6b, 6c are optical sensors or magnetic sensors according to the medium of the pallet number PN. When the identification code IDc and the pallet number PN are composed of, for example, 8 bits, it means that a maximum of 256 vehicles and pallets P can be associated and identified.

The ID code analysis / setting circuit 8 determines whether or not the received identification code IDc and the pallet number PN match, that is, the pallet P currently located on the ground surface and the vehicle C that is going to park. If the two do not match, a predetermined audio data is read from the memory circuit 9 and supplied to the reproducing circuit 7, or the warning signal S1 is directly sent to the reproducing circuit 10. Further, in order to automatically move the pallet P corresponding to the vehicle C to be parked to the ground surface, the pallet number PN (= identification code IDc) corresponding to the vehicle C is sent to the interface circuit 12 as necessary. Put out. Which of the voice data, the warning signal S1, and the pallet number PN should be sent may be appropriately determined by the facilities of the parking lot, for example, one or a combination of two or more. .

The memory circuit 9 stores the above-mentioned voice data in advance when a warning is issued by voice. The voice data is a message informing that the pallet is different, such as "The pallet is different" or "The pallet will be moved. Please wait".

Next, the reproducing circuit 10 converts the audio data into an analog signal and adjusts the level so that the audio data has a predetermined level, and then the speaker 11 produces the above-mentioned message as audio. Alternatively, according to the warning signal S1 supplied from the ID code / pallet number analysis / setting circuit 8, a warning lamp (not shown) may be driven or an alarm sound may be emitted. Further, the interface circuit 12 converts the palette number PN corresponding to the identification code IDc read from the memory circuit 9 into a predetermined data format and outputs it to the outside. This pallet number PN is used to move the pallet P of the corresponding pallet number P N to the ground surface by, for example, a pallet driving system (not shown).

A-3. Block Configuration of Transponder Next, the transponder 2 includes an antenna 13, a transmission / reception circuit 14, and a memory circuit 15. As described above, the antenna 13 takes out electric power generated by electromagnetic induction when entering the high frequency magnetic field of the reader 1, and transmits the identification code IDc from the transmission / reception circuit 14 to the reader 1 as a radio signal. The transmission / reception circuit 14 reads the identification code IDc stored in advance in the memory circuit 15 and modulates the identification code IDc (for example, FSK-FM) at the timing when power is supplied to the high-frequency magnetic field of the reader 1. , And automatically transmits through the antenna 13 by radio frequency (for example, 100 kHz to 500 kHz band). The memory circuit 15 stores in advance the identification code IDc for identifying the vehicle (or the owner), that is, the code having the same value as the pallet number PN of the pallet P to be parked. As described above, the transponder 2 does not have a power source and obtains electric power when it enters the high-frequency magnetic field of the reader 1, which makes it extremely compact and requires replacement of the battery or the like. It has the feature that it does not exist.

Here, FIG. 4 is a conceptual diagram showing a mounting position of the above-mentioned transponder 2 on the vehicle, and the transponder 2 is mounted on a rear body of the vehicle C, a rear bumper or the like. This is because, generally, in a multi-story parking lot using a pallet as described in the present embodiment, the pallet is retracted and stored in the parking lot. The position is not limited to this as long as it is a position that easily responds to the high frequency magnetic field generated by the antennas 3a and 3b.

B. Operation of Embodiment Next, the operation of the parking place identification system described above will be described with reference to FIGS. 5 to 8. First, the initial state of the pallets P1 to P8 is assumed to be the state shown in FIG. That is, it is assumed that the vehicles C2, C4, C7 of the pallets P2, P4, P7 can leave the pallet without moving the pallet. Here, a case will be described in which, after the vehicles C4 and C5 of the palette P4 and the pallet P5 have been unloaded, the vehicle of the previously unloaded pallet P4 is unloaded.

First, since the pallet P4 is located on the ground surface, the vehicle C4 of the pallet P4 exits as it is. Next, when the vehicle C5 of the pallet P5 leaves, since the pallet P5 is located underground, the pallets P4 and P5 are simultaneously raised as described above. As a result, the pallet 5 is located on the ground surface as shown in FIG. 6, and in this state, the vehicle C5 of the pallet P5 is unloaded. The movement of the pallet P at the time of warehousing is carried out by the driver or manager of the vehicle and is not related to the present proposal.

Next, in the above-mentioned state, the vehicle C4 of the pallet P4 returns and tries to store the vehicle. As shown in FIG. 7, the vehicle C4 retracts in front of the pallet P5. Since the high frequency magnetic field is generated from the reader 1 from the antenna 3b at all times or at a predetermined time interval, when the retreating vehicle C4 approaches, the transponder 2 provided at the rear of the vehicle C4 is Since it enters the high-frequency magnetic field, power is supplied and it enters the operating state. The transponder 2 automatically modulates the identification code IDc stored in advance in the memory circuit 15 by the transmission / reception circuit 14 and transmits it from the antenna 13 as a radio signal.

On the other hand, in the reader 1, the radio signal from the transponder 2 is received by the antenna 3 b, the transmitting / receiving circuit 5 detects and demodulates the identification code IDc, and the ID code / pallet number analyzing / setting circuit is obtained. Supply to 8. In the pallet number detection circuit 7, the sensor 6b reads the pallet number PN of the pallet P5 currently located on the ground surface and supplies it to the ID code / pallet number analysis / setting circuit 8. The ID code / pallet number analysis / setting circuit 8 determines whether or not the received identification code IDc and the detected pallet number PN match. That is, it is determined whether or not the pallet P currently located on the ground surface corresponds to the vehicle C4 attempting to park. In this case, the pallet P currently located on the ground surface is the pallet P5, and the illustrated vehicle C4 is a vehicle that must be parked on the pallet P4, so the two do not match. As a result, in the ID code / palette number analysis / setting circuit 8, the predetermined audio data is read from the memory circuit 9 and supplied to the reproducing circuit 7, or the warning signal S1 is directly sent to the reproducing circuit 7. To be done.

In the reproducing circuit 10, the pallet P5 currently located on the ground plane is generated by sounding the above-mentioned voice data as a message from the speaker 11 as a voice or activating a warning lamp or alarm (not shown) according to the warning signal S1. Notify that the palette is different. The driver of the vehicle C4 moves his or her pallet P (in this case, the pallet P4) to the ground surface by operating an operation panel (not shown).

Here, FIG. 8 is a conceptual diagram showing a state after the pallet P4 has been moved. As shown in the figure, in this state, the pallet P4 is located on the ground surface and the pallet P5 is underground. To position. Even in this state, as described above, since the high frequency magnetic field is generated from the antenna 3b of the reader 1, the transponder 2 arranged at the rear portion of the vehicle C4 is automatically stored in the memory circuit 15 in advance. The stored identification code IDc is transmitted as a radio signal from the antenna 13.

On the other hand, in the reader 1, the radio signal from the transponder 2 is received by the antenna 3 b, the identification code IDc is taken out, and supplied to the ID code / pallet number analysis / setting circuit 8. In the pallet number detecting circuit 7, the sensor 6b reads the pallet number PN of the pallet P4 currently located on the ground surface and supplies it to the ID code / pallet number analyzing / setting circuit 8. In this case, since the vehicle C4 shown in the figure is a vehicle corresponding to the pallet P4, the identification code IDc and the pallet number PN match, so a warning that the pallet P currently located on the ground plane is a different pallet is issued. Not done. Therefore, the driver of the vehicle C4 stores the vehicle in the pallet P4 as it is. The operations of the reader 1 and the transponder 2 described above are basically the same in the other pallets P1, P2, P3, P6, P7 and P8, except that the movement patterns of the pallets are different. As a result, it is possible to prevent the problem that the vehicle erroneously stores the pallet P into which it should be stored.

When the predetermined pallet P is automatically moved by the pallet drive system based on the pallet number P N output from the ID code / pallet number analysis / setting circuit 8, as described above, The pallet number PN stored in the memory circuit 9 may be supplied to the pallet driving system (not shown) via the interface circuit 12. In this case, the pallet drive system normally lowers the pallets P4 and P5 simultaneously in accordance with the pallet number PN instead of the personal identification number input from the operation panel, and automatically moves the pallet P4 to the ground surface. Therefore, the driver does not need to perform an operation for moving the pallet P.

As described above, in the above-described embodiment, since the electric power induced by the high frequency magnetic field generated by the reader 1 is used as the power source of the transponder 2 arranged in the vehicle C, a battery is used. There is no need to circulate the power supply, and the burden of maintenance can be reduced. When the identification code IDc for each vehicle is set in the transponder 2 arranged in the vehicle C and the vehicle C is loaded, the identification code IDc of the transponder 2 and the pallet located on the current ground plane are automatically set. It is judged whether or not the pallet number PN of P matches, and if it does not match, an alarm is issued, so the mistake of parking on another pallet P can be prevented. Further, the antennas 3a, 3b, 3c and the sensors 6a, 6b, 6c need not be provided for each pallet P, but may be provided for the pallet P located on the ground surface, so that an inexpensive system can be constructed. Further, if the pallet P corresponding to the vehicle is not located on the ground surface, the pallet number PN (= identification code IDc) of the pallet P corresponding to the vehicle C is supplied to a pallet drive system (not shown). The predetermined pallet P can be automatically moved to the ground surface without human intervention.

In the above-mentioned embodiment, the antennas 3a, 3b, 3c and the sensors 6a, 6b, 6c are provided for each of the pallets P2, P4, P7 located on the ground surface. , There may be a limit to one doorway. Needless to say, in such a case, it may be provided only on the entrance pallet. In addition, in the above-mentioned embodiment, when the pallet P located on the ground surface is a different pallet, a warning is given by voice, alarm sound, alarm lamp, etc. In addition to this, the vehicle is parked. In order to prevent this, the leading end of the pallet P may be raised to forcibly prevent the warehousing of the vehicle.
