DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card system for wirelessly acquiring personal information stored in a card previously given to a user as a means for acquiring personal information of a card holder.

[0002]

2. Description of the Related Art Conventionally, a card system of this type receives a reminder radio wave, which is a request for transmission of personal information of a card holder stored in the card, from a transmitting device, and receives the contents of the memory in the card. Was unconditionally sent back wirelessly.

[0003]

However, in the conventional wireless card system, when a reminder radio wave is received, the data stored in the memory in the card is unconditionally transmitted back wirelessly. If this type of system is introduced in an environment where it is highly likely that many card holders will gather at the same time, such as in a store, radio waves from multiple cards will be congested, and information from individual cards will be correctly distinguished and received I couldn't do that.

In addition, since the contents of a memory storing and holding tens of items of various data are all unconditionally sent back wirelessly, unnecessary information may be transmitted simultaneously depending on the situation. However, by the time the card is sent, the card holder will be out of the communicable area, and the transmitter with the largest power consumption of the card will work for a long time, thus shortening the life of the internal battery. there were.

The present invention has been made to solve these problems, and has a function of sequentially transmitting a plurality of cards without causing interference by grasping the surrounding conditions and transmitting only necessary information back. An object of the present invention is to provide a wireless card system that achieves a reduction in transmission time from a card and a longer life of a built-in battery.

[0006]

According to the present invention, it is possible to store and retain personal information of a card holder, receive a reminder radio wave as a transmission request for the personal information, and transmit the personal information to the reminder radio wave. A card, a transmitting device that transmits a reminder radio wave to urge the card holder to transmit the personal information of the card holder stored in the card, and a receiving device that receives the personal information transmitted from the card. In a wireless card system that wirelessly obtains personal information of a card holder, a reception for selectively receiving a first frequency for transmitting a reminder radio wave from the transmitting device and a second frequency for transmitting personal information from the card. Means, means for monitoring the presence or absence of a radio wave at a second frequency from another card within a predetermined time, and transmission of personal information from the own card according to the presence or absence of the radio wave by the means. Is characterized and Gosuru transmission means that is provided in the card.

[0007]

According to the present invention having the above-described structure, the contents of the memory in the card are not returned unconditionally only in accordance with the presence or absence of the reminder radio wave from the transmitting device, but prior to the radio wave transmission. Monitor the surrounding radio wave condition, confirm that there is no radio wave transmission from other cards, transmit radio waves sequentially,
To return only the information in the memory area designated by the reminder radio wave and extend the life of the built-in battery, only the radio wave receiver is normally operated to supply power to all circuits only when the reminder radio wave is received.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention.
The figure shows the relationship between a transmitting device that emits a reminder radio wave and a receiving device that receives information from a card. FIG. 2 is a diagram showing an example of items of personal information stored and held in a memory in the wireless card of the present invention. 3 and 4
FIG. 3 is a diagram for explaining a communication situation between a transmitting apparatus and a card according to the present invention. FIG. 3 shows a case where only one card exists in a communicable area, and FIG. FIG. 7 is a diagram showing an operation when the information exists in the.

In FIG. 1, a transmitting device for transmitting a reminder radio wave to the wireless card 31 includes a content designation command setting unit 11 for specifying information contents to be read out and a reminder radio wave transmission unit 1.
2, the transmission antenna 13 and the like. Also,
A receiving device for receiving information from the wireless card 31 includes a receiving antenna 21, an information receiving unit 22, an information analyzing unit 23 for analyzing the received information content, and a display for transmitting the analyzed information content to hotel employees and the like. It comprises a unit 24 and the like.

[0010] Also, inside the wireless card 31, the receiving antenna 32 in the card and the radio wave receiving unit 33 for receiving the prompting radio wave from the transmitting device and the transmitting radio wave from another wireless card are included in the prompting radio wave. A content designation command analyzing unit 34 for analyzing a content designation command to be read, a memory content reading unit 35 for reading out only predetermined information from an ID card memory 38 in the card based on control information from the content designation command analysis unit 34, a memory content An information transmitting unit 36 for transmitting the information read by the reading unit 35 to the receiving device and an in-card transmitting antenna 37 are mounted. In addition, a built-in battery 39 for operating these circuits and a power control unit 40 for supplying power to all circuits only when a reminder radio wave is received to prolong the battery life are mounted. Further, in order to prevent congestion and erroneous reception due to random transmission by a plurality of cards, the radio wave receiving unit 33 is controlled prior to information transmission from the cards to confirm whether or not there is transmission from a peripheral card. A control unit 41 is provided with a transmission control unit 42 that receives information on the presence or absence of transmission from a nearby card from the radio wave reception unit 33, controls the memory content reading unit 35 and the information transmission unit 36, and instructs the information transmission timing. This is a big difference from this type of conventional wireless card.

Next, the operation of such a system when a card approaches a communicable area will be described. First, in order to explain a basic operation, an operation in a case where only one card exists in one communicable area will be described with reference to FIGS.

When the person holding the wireless card 31 approaches the prompting radio wave transmitting antenna 13, the radio wave receiving unit 33 receives the prompting radio wave via the receiving antenna 32 in the card. Then, the radio wave receiving unit 33 controls the power control unit 40 to supply power to all circuits in the card.

Then, the content designation command analysis section 34 analyzes the content designation command included in the reminder radio wave and selects information to be sent back. For example, in the system according to the present invention, when the transmitting device and the receiving device are installed near the entrance of the restaurant in the hotel, the content designation command is selected from among many personal information items shown in FIG.
For example, only the name, preference, and service class of the holder are specified. Next, this example is an example in which only one card exists in one communicable area as described above. However, in order to confirm the presence or absence of another card, a predetermined time (T
w) It monitors whether or not there is a radio wave from another card at the transmission frequency of the card. If there is no radio wave at this frequency during the Tw time, the memory content reading unit 35 receives information from the content specifying command analyzing unit 34 and specifies the specified command, for example, “name”, “preference”, and “service class” area. The information is read from the memory 38 in the card.
Then, the information transmitting unit 36 transmits the in-card transmitting antenna 3.
7 to send.

The radio wave is received by the information receiving unit 22 via the receiving antenna 21, the information content is analyzed by the information analyzing unit 23, and the content is displayed on a display unit installed at a restaurant entrance at a hidden location. 24.

The restaurant employee can read the information displayed on the display unit 24 before the card holder arrives at the restaurant entrance, so that he can be called by the name of the person, thereby improving the serviceability. In addition to this, it is possible to provide a satisfactory service to the card holder, for example, it is possible to respond to the preference of the person when selecting and cooking the dish.

Further, in the wireless card system according to the present invention, when a plurality of card holders enter a communicable area at the same time, such as a hotel or a store, the conventional wireless card system uses radio waves from a plurality of cards. Is congested, and it is possible to eliminate a drawback that information from individual cards cannot be correctly distinguished and received.

The operation in such a situation will be described with reference to FIG. In this case, when each card in the same communicable area receives a reminder radio wave, it receives a transmission frequency from the card for a certain period of time before transmitting from the card and checks whether there is radio wave at this frequency. The steps up to this point are the same as those described above. Then, when a radio wave from another card existing in the same communicable area is detected during the Tw time, the reception of this frequency is continued,
After the radio wave from the other card disappears, the monitoring is continued for the Tw time. If no new radio wave appears at this frequency during the Tw time, the information of the designated area in the memory is immediately transmitted, and a new radio wave is transmitted. , The operation is continued to continue receiving this frequency.

By performing such an operation, radio waves from a plurality of cards can be sequentially transmitted without congestion. Further, in this operation, as shown in FIG. 4, there is a difference (Tw1 <Tw2) in the monitoring time Tw of the transmission frequency according to the service grade of the card holder (the service class of the card 1 is higher than that of the card 2). By doing so, it becomes possible to transmit in order from the card possessed by a customer of a higher service class, which needs to pay more attention to the hotel or store. In other words, by setting a shorter Tw for a card possessed by a customer having a higher service class, transmission can be started prior to another card having a longer Tw.

Further, since the wireless card of the present invention performs an operation of sending back only the information item designated by the content designation command, the transmission time per card can be shortened, and a plurality of cards can be placed in the same communicable area. Even in the case where it is present, it is possible to reduce the risk of exiting the communicable area before the end of transmission.

The present invention is not limited to the above embodiment. For example, in the above embodiment, an example of using personal information in a hotel or a store has been described. However, the personal information items stored and held in the memory in the card illustrated in FIG. It can be used for security management, entry / exit management, attendance / departure management, etc. in facilities such as offices, research laboratories, and factories by adding a function to control the opening and closing of electronic locks. In addition, various modifications can be made without departing from the scope of the present invention.

[0021]

As described above, according to the present invention,
Even if multiple cards exist in the same communicable area,
The radio waves from the cards are not congested, and the information from the individual cards can be sequentially and correctly received from the card with the higher service class. In addition, since only the specified information is sent back, the communication time can be shortened, so that the waiting time until transmission when there are a plurality of cards is shortened, and the danger of falling out of the communicable area before the end of transmission is reduced. In addition, since the communication time is short, there is also an effect of extending the life of the built-in battery.
