Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a location search system that searches for the location of a moving object such as a person or a car.
[0002]
[Prior art]
For example, as a system for searching for a person's location using radio waves, the PHS (Personal Handyphone System) is used as described in pages 125 to 127 of July 15, 1996 in the magazine “Nikkei Electronics”. There is what I did. This is because the PHS terminal is carried by a person, the radio waves automatically transmitted by the PHS terminal are received by the three base stations, the electric field strength at each reception point is sent to the center, and the PHS terminal is based on the principle of triangulation at the center. That is, the position of a person, that is, the position of a person is estimated.
[0003]
In addition, what is described in Japanese Patent Application Laid-Open No. 8-65413 is a system in which a person combines a mobile phone and a GPS (Grobal Positioning System) receiver. Carry it and when you receive a call from a guardian who needs protection, the current location information automatically obtained from GPS Mobile phone It is sent from the telephone to the guardian.
[0004]
[Problems to be solved by the invention]
In the case of using the former PHS terminal, there are restrictions on the number of slave stations that can access one base station, so there are situations in which connection is not possible when there are many users of PHS terminals as in the city center. In addition, there are few base stations in suburbs such as residential areas, and therefore there is a problem that is not suitable for searching that requires urgent and certainty.
[0005]
In addition, a device using a combination of the latter mobile phone and GPS receiver does not function unless the two conditions of being a mobile phone call area and a location where GPS radio waves can be received are satisfied. Therefore, there is still a problem that is not suitable for searching that requires urgent and certainty.
[0006]
In addition, both have a common problem that they are large and heavy to carry at all times. For example, they are unsuitable for use in sewing and carrying on clothes. Furthermore, mobile phones have a problem in that transmitted radio waves adversely affect the cardiac pacemaker.
[0007]
Therefore, Book The invention makes it possible to reduce the size and weight of a device placed on a mobile body such as a person, so that it can be easily carried at all times, does not adversely affect the cardiac pacemaker, and has a wireless connection state with a base station or a satellite. To provide a location search system that can perform a reliable location search without any restrictions such as the reception state of radio waves.
[0008]
Also, Book The invention further provides a location search system that enables quick registration when registering an ID code and a report contact number corresponding to a device arranged on a mobile object such as a person as information for search.
[0009]
Also, Book The invention further provides a location search system that is well suited for searches requiring urgent and certainty.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
In this embodiment, a mobile identification device including an interrogator and a responder is used, and the interrogator is arranged in a store and the responder is arranged in a moving body, for example, a person.
[0016]
As shown in FIG. 1, when an interrogation radio wave is emitted to a store S1 and a response radio wave modulated by an ID code is received from the responder 1, an interrogator 2 extracts the ID code from the response radio wave and outputs the ID code. For example, a POS terminal device 3 that performs sales registration processing of products in the store S1, and a barcode scanner 4 that connects to the POS terminal device 3 and reads product barcodes and inputs product information. It is arranged. The other stores S2 to Sn are similarly provided with an interrogator, a POS terminal device, and a barcode scanner.
[0017]
The POS terminal devices 3 of the stores S1 to Sn are provided with communication means and connected to a host computer 6 provided in the center ST via a communication line, for example, a public telephone network 5. A storage device 7 is connected to the host computer 6.
As shown in FIG. 2, the interrogator 2 is attached to, for example, the upper portion of the outer wall facing the road L in the store S1. The responder 1 is fixed to, for example, clothes of a person M who needs protection. The attachment position of the interrogator 2 is not limited to this, and it may be attached to a post or other structure near the road.
[0018]
The relationship between the interrogator 2 and the responder 1 is that when the interrogator 2 constantly emits an interrogation radio wave and the responder 1 enters a range where it can transmit and receive with the interrogator 2, the responder 1 A response radio wave modulated by an ID code is emitted. When the interrogator 2 receives a response radio wave modulated with an ID code from the responder 1, the interrogator 2 extracts the ID code from the response radio wave and outputs the ID code to the POS terminal device 3. The radio system of the interrogator 2 and the responder 1 uses the 2.4 GHz band of the local radio station defined in Article 3, Paragraph 1, Item 18 of the Radio Law Enforcement Regulations.
[0019]
For example, when a directional antenna having a maximum absolute gain of 20 dB is arranged in the interrogator 2 and a dipole antenna having an absolute gain of 2.14 dB is used as the responder 1, the interrogator 2 in the direction of the directivity maximum gain of the interrogator side antenna The range in which the responder 1 can transmit and receive is about 2 m when the responder 1 is a passive reflection type without a battery, and is about 10 m when the battery type retransmission type is used.
[0020]
In this embodiment, as shown in FIG. 3, the interrogator 2 includes a transmission planar patch antenna 21, a reception planar patch antenna 22, a transmission unit 23 connected to the transmission planar patch antenna 21, and a reception plane. The receiving unit 24 connected to the patch antenna 22, the transmitting unit 23, and the receiving unit 24 are controlled, and the control unit 25 is configured by a microcomputer that communicates with the POS terminal device 3. In order to improve the power efficiency of transmission / reception, each of the planar patch antennas 21 and 22 has a narrow directivity with an H in-plane directivity shown in FIG. 4 (a) and an E in-plane directivity shown in FIG. 4 (b). Therefore, an absolute gain of 10 dB is obtained in the maximum gain direction.
[0021]
The transmission unit 23 is configured to supply a 300 mW carrier wave intermittently to the transmission antenna 21 at a frequency of about 10 times per second as controlled by the control unit 25. The receiving unit 24 demodulates a received signal from the receiving antenna 22 and supplies demodulated data to the control unit 25. The control unit 25 transmits demodulated data from the receiving unit 24 to the POS terminal device 3. The control unit 25 controls the start and stop of intermittent transmission of interrogation radio waves according to commands from the POS terminal device 3.
[0022]
As shown in FIG. 5, the responder 1 embeds a circuit board 12 in which each circuit part is formed in a plate-shaped resin casing 11 that is rectangular and protrudes in a triangular shape at both ends in the longitudinal direction. Snap buttons 14a and 14b for printing a bar code 13 corresponding to the ID code set on the responder 1 on the surface of the housing 11 and fixing the responder 1 to clothes on a triangular protrusion. It is the structure which attached.
[0023]
The responder 1 is, for example, a passive reflection type, and a circuit shown in FIG. That is, a dipole antenna 15 for transmission / reception formed with a printed pattern, a detector 16, a voltage stabilizing circuit 17, a high frequency switch 18, a CPU 19, and a ROM 20 are provided, and the interrogation radio wave from the interrogator 2 is transmitted to the dipole antenna. 15, rectified and stabilized to direct current by the detector 16 and the voltage stabilization circuit 17, and supplied as power to the CPU 19, ROM 20 and high frequency switch 18. When this power is supplied, the CPU 19 reads the ID code stored in the ROM 20 and controls the opening and closing of the high-frequency switch 18 according to the contents, that is, the bit string consisting of digital codes 0 and 1. .
[0024]
For example, when the digital code is 0, the open control is performed, when the digital code is 1, the close control is performed, and when the high frequency switch 18 is open, the feeding point impedance of the dipole antenna 15 and the input impedance of the detector 16 are matched. The power reflection at the point is small, and most of the received power is transmitted to the detector 16 and thereafter. However, when the high-frequency switch 18 is closed, the feeding point of the dipole antenna 15 is short-circuited, resulting in an impedance mismatching state. The high-frequency power received by the dipole antenna 15 causes total reflection at this short-circuiting point, and again from the dipole antenna 15. Re-emitted into space. The re-radiated radio wave is received by the interrogator 2 as a response radio wave. This response radio wave corresponds to the opening / closing operation of the high frequency switch 18 and is ASK (Amplitude Shyft Keying) modulated according to the ID code of the responder 1.
[0025]
As shown in FIG. 7, the POS terminal device 3 includes a CPU (central processing unit) 31, a ROM 32 storing program data for the CPU 31 to control each unit, a RAM 33 used for data processing and data registration, A scanner interface 34 for inputting barcode data from the barcode scanner 4, an interrogator interface 35 for outputting instructions to the interrogator 2 and inputting demodulated data from the interrogator 2, A product with a file that sets the product name, unit price, etc. for each product code, a file that manages the total sales amount and total sales points for each product code, etc. Via the host device interface 36 for transmitting and receiving and the public telephone network 5, the center ST A communication modem 37 and an I / O port 38 for controlling communication with the computer 6 are provided. The CPU 31, ROM 32, RAM 33, interfaces 34, 35 and 36, communication control unit 37 and I / O port 38 are bus lines. 39 is connected. The I / O port 38 has a keyboard 40 with various keys, a printer 41 for printing product registration data on receipts and journals, a display 42 for displaying product registration data, and a drawer for opening the drawer. The opening mechanism 43 and the hard disk device 44 capable of storing a large number of ID codes of the responder 1 as location search information and the corresponding telephone numbers of the report destinations are connected.
[0026]
In a normal registration operation, the POS terminal device 3 takes in a product code obtained by the barcode scanner 4 reading a barcode from a product through the scanner interface 34, temporarily stores it in the RAM 33, and then stores it in the RAM 33. The product code is inquired to the store processor via the menu, and the product name, unit price, etc. corresponding to the product code are received from the store processor, stored in the RAM 33 and displayed on the display 42. At this time, when a plurality of the same products are registered, the number is input from the keyboard 40 and the display 42 displays the unit price × the number of money. Further, the printer 41 prints the product name, unit price, etc. on the receipt and journal.
[0027]
When the above product registration process is repeated for the product purchased by the customer, and finally the registration lock key is operated on the keyboard 40, the customer is registered and the total amount of the product is calculated and displayed on the display 42. Further, the printer 41 prints the total amount on the receipt and the journal and issues a receipt. Then, the customer pays based on the total amount displayed on the display 42. The series of data registered for the customer and the total data are transmitted to the store processor via the host device interface 36, and the store processor receives this and updates the file.
[0028]
The above is a normal registration operation performed by the POS terminal device 3, and the CPU 31 performs processing based on the program. The CPU 31 of the POS terminal device 3 also performs search information registration processing described below. . Switching to search information registration processing is performed by, for example, operating a specific key on the keyboard 40.
That is, when the customer brings the responder 1 sold in the store, the bar code printed on the responder 1 is read by the bar code scanner 4 by operating a specific key on the keyboard 40. The read data is taken in via the scanner interface 34, and the CPU 31 converts this data into a numerical value, that is, an ID code, and temporarily stores it in the RAM 33.
[0029]
On the other hand, the customer contacts the telephone number to be notified and inputs it by key operation on the keyboard 40. The CPU 31 stores the ID code previously input and this report destination contact telephone number in the hard disk of the hard disk device 44 in association with each other. Further, the CPU 31 controls the communication modem 37 to transmit the ID code and the report destination telephone number stored in the hard disk to the host computer 6 of the center ST via the public telephone network 5. The host computer 6 additionally registers the received ID code and report destination contact telephone number in the storage device 7 as new search information. In addition, the host computer 6 transmits the newly registered new search information to the POS terminal device of another store. The POS terminal device at another store stores the new search information received from the host computer 6 in the hard disk of its own hard disk device.
By performing the above processing, the search information including the ID code and the contact telephone number can be stored in the hard disk device of each store.
[0030]
Then, when there is a search request from the customer, for example, the reporter contact telephone number of the corresponding responder is key-input on the keyboard 40. As a result, the CPU 31 transmits an operation start command to the interrogator 2 via the interrogator interface 35. Further, the CPU 31 notifies the request information to the POS terminal devices of other stores via the host computer 6 of the center ST. As a result, the POS terminal devices at other stores also send an operation start command to the same interrogator. The interrogator 2 that has received the operation start command emits an interrogation radio wave toward the road L surface.
[0031]
In this state, when a person wearing the transponder 1 enters a range where the interrogator 2 can transmit and receive with the transponder 1, the transponder 1 receives the interrogation radio wave from the interrogator 2 and modulates it with the ID code. A response radio wave is emitted. The interrogator 2 receives this response radio wave, demodulates it, and transmits it to the POS terminal device 3 as demodulated data. The CPU 31 of the POS terminal device 3 converts the demodulated data received via the interrogator interface 35 into an ID code, and compares it with the ID code stored in the hard disk device 44 to retrieve the corresponding ID code. When a corresponding ID code is searched, the report destination contact telephone number corresponding to this ID code is read out and a call is automatically made to the report destination via the communication modem 37. Further, the CPU 31 has a time counting function, the store name and location information are stored in the hard disk device 44, and the CPU 31 performs synthesized speech processing of the voice and sends the responder 1 with the synthesized voice to the report destination. Tell the store name, location, and time of discovery.
[0032]
Thus, in the location search system, the structure of the responder 1 can be extremely small and light, and can be always carried easily. And if it sews on a person's clothes etc., it can also prevent that the responder 1 is lost. Further, since the response radio wave emitted by the responder 1 is extremely weak, there is no possibility of adversely affecting the cardiac pacemaker.
In addition, there is no restriction such as a wireless connection state with a base station such as PHS or a satellite radio wave reception state such as GPS, and a reliable location search can be performed by placing the responder 1 within a range where the interrogator 2 can transmit and receive. Moreover, since a general user does not carry it like PHS, the problem of infringement of privacy by searching to the current position of an unrelated general user does not occur.
[0033]
Further, if the customer brings the responder 1 sold in the store, the ID code corresponding to the responder 1 and the reporter contact telephone number are immediately searched as search information by the barcode scanner 4 and the keyboard 40 of the POS terminal device 3. It is possible to register in the hard disk device 44 and to respond quickly. Accordingly, the customer can immediately use the responder 1 by bringing it back and sewing it to the clothes of a person who needs protection.
[0034]
Further, if the search information is registered in the POS terminal device 3 of one store, the search information is automatically registered in the POS terminal device of another store via the host computer 6 of the center ST. It is possible to search for the location of the responder 1, and in particular, since there are a lot of stores scattered throughout the city and suburbs, it is necessary to construct a system that is well suited for searches that require urgent and certainty. Can do.
[0035]
In this embodiment, an example in which a passive reflection type responder is used as the responder 1 has been described. However, a battery-type retransmission type responder can also be used as the responder 1.
As shown in FIG. 8, the battery-type retransmission-type transponder includes three dipole antennas, a dipole antenna 51 for detecting an interrogation radio wave, a dipole antenna 52 for reception, and a dipole antenna 53 for retransmission. The interrogation radio wave from the interrogator 2 is received by the interrogation radio wave detection dipole antenna 51, converted into a DC voltage by the detector 54, and supplied to the detector 55. Then, the detection unit 55 compares the DC voltage with the reference voltage, and when the DC voltage exceeds the reference voltage, the detection unit 55 supplies a signal indicating that the interrogation radio wave has been received to the CPU 56. The CPU 56 that has received the interrogation radio wave reads the ID code from the ROM 57 and supplies the ID code to the modulation unit 58 as a serial bit string. The modulation unit 58 is configured to ASK-modulate a high-frequency signal received by the reception dipole antenna 52 in accordance with an input bit string, and to emit the response radio wave from the retransmission credit dipole antenna 53. This responder has a built-in battery 59 and supplies power to the detector 54, the detection unit 55, the CPU 56, the ROM 57, and the modulation unit 58, respectively.
Even if such a battery-powered re-transmission type responder is used, the same effect as that of the above-described embodiment can be obtained.
[0036]
(Second Embodiment)
This embodiment describes a case where a mobile identification device including a transmitter and a receiver is used, the receiver is disposed in a store, and the transmitter is disposed in a moving body, for example, a person. The same parts as those in the first embodiment are denoted by the same reference numerals, and different points will be described.
As shown in FIG. 9, the responder 1 in the first embodiment is replaced with a transmitter 61 and the interrogator 2 is replaced with a receiver 62.
[0037]
As shown in FIG. 10, the receiver 62 is attached to the upper part of the outer wall facing the road L in the store S1, for example. The transmitter 61 is fixed to, for example, clothes of a person M who needs protection. The mounting position of the receiver 62 is not limited to this, and it may be mounted on a post or other structure near the road.
[0038]
The radio system of the transmitter 61 and the receiver 62 uses weak radio waves of 320 MHz band, and when a 5-element Yagi antenna with a maximum absolute gain of 10 dB is used on the receiver 62 side, the directivity of the receiver side antenna is maximum. The practical range that the receiver 62 can receive in the gain direction is about 20 m.
[0039]
As shown in FIG. 11, the receiver 62 includes a receiving antenna 621 composed of a five-element Yagi antenna with a maximum absolute gain of 10 dB. The receiving antenna 621 receives a 320 MHz radio wave from the transmitter 61 to reduce noise. After amplification by the amplifier 622, the frequency converter 623 mixes with the 320.455 MHz local transmission signal from the local transmitter 624 and converts it to an intermediate frequency signal of 455 KHz. The intermediate frequency signal is demodulated into an analog detection signal by a demodulator 625, then binarized by a binarization circuit 626 comprising a voltage comparator, a digital ID code is taken out, and this ID code is supplied to the microcomputer 627. .
[0040]
The microcomputer 627 transmits the ID code to the POS terminal device 3, and the POS terminal device 3 takes in the ID code via a receiver interface provided in place of the interrogator interface. The microcomputer 627 controls the start and stop of the reception operation of the receiver 62 according to a command from the POS terminal device 3.
[0041]
As shown in FIG. 12, the transmitter 61 includes a transmission multiplication circuit 611 that performs transmission multiplication by a crystal oscillator, and supplies a carrier wave of 320 MHz from the transmission multiplication circuit 611 to the ASK modulator 612. A CPU 613 is provided, and the CPU 613 reads an ID code from the ROM 614 and supplies the ID code as a serial bit string to the ASK modulator 612. The ASK modulator 612 ASK modulates the carrier wave from the transmission frequency multiplier 611 with the ID code from the CPU 613. The modulated signal from the ASK modulator 612 is amplified by the high frequency amplifier 615 and then emitted from the transmission loop antenna 616.
[0042]
The transmitter 61 includes a battery 617, and outputs the output of the battery 617 to the transmission multiplication circuit 611, the ASK modulator 612, the CPU 613, the ROM 614, and the high-frequency amplifier 615 via an intermittent operation control circuit 618 every 0.5 sec. It is supplied intermittently with a duty cycle of 50 msec. Accordingly, the emission of radio waves from the transmitter 61 repeats the operation of transmitting the ID code repeatedly for 50 msec, then stopping the transmission for 0.5 sec, and then transmitting the ID code again for 50 msec. ing.
[0043]
In this way, even when the mobile identification device including the transmitter 61 and the receiver 62 is used, if the person wearing the transmitter 61 enters the practical range that the receiver 62 can receive, the receiver 62 transmits the message. The radio wave emitted from the device 61 can be reliably received and demodulated, and the demodulated data can be transmitted to the POS terminal device 3. In addition, the transmitter 61 can be reduced in size and weight.
Therefore, this location search system can provide the same operational effects as the location search system of the first embodiment.
[0044]
In each of the above-described embodiments, the interrogator 2 or the receiver 62 receives the response radio wave from the responder 1 or the radio wave transmitted by the transmitter 61 in each store, and transmits the demodulated data to the POS terminal device 3. The POS terminal device 3 obtains an ID code from the demodulated data, collates and searches with the ID code stored in the hard disk device 44, reads out the corresponding report contact telephone number, automatically calls the report destination, and responds to the responder 1 Alternatively, the store name, location, and time at which the transmitter 61 is found are communicated, but the present invention is not necessarily limited to this. For example, when a customer asks the center ST about the search status, The operator inputs the corresponding report contact telephone number from the keyboard of the host computer 6, whereby the host computer 6 reads the corresponding communication address from the storage device 7. The contact telephone number is searched, and if there is a corresponding report contact telephone number, the host computer 6 reports the information obtained by inquiring the search status to the POS terminal device 3 of each store to the report contact telephone number. It may be a configuration.
[0045]
The report to the report destination is not limited to the telephone contact based on the report destination contact telephone number, but may be configured to contact by e-mail or the like if the customer's personal computer is connected to the host computer 6. . Further, the communication line is not limited to a telephone line but may be an ISDN line.
[0046]
Further, the map information of the place to be searched is stored in the storage device 7 of the center ST, and when there is an inquiry from the customer, the host computer 6 is based on the search information from the POS terminal device 3 of each store. As shown in FIG. 13, a screen displaying the passage location, the time and current estimated position on the corresponding map is displayed on the display, and the screen information is transmitted as an e-mail to the customer's personal computer. It may be a thing.
[0047]
If the customer has a facsimile machine, the host computer 6 prints a screen showing the passage location, the time at that time, and the current estimated position on the corresponding map with a printer, The operator may send it to the customer's facsimile machine.
[0048]
In each of the embodiments, the case where the moving body is a person and the responder or the transmitter is attached to the person is described. However, the present invention is not necessarily limited thereto, and the moving body is, for example, a wheelchair. A responder or transmitter may be attached to the.
In addition, this invention is not limited to these, A various deformation | transformation is possible in the range which does not deviate from the summary of this invention.
