Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transponder with a display function,
For example, it is used in mobile object identification systems, room entry/exit control systems, electronic ticket systems, etc.

[Prior Art] Conventionally, an interrogator installed at a point where a moving object passes through reads information from a transponder attached to the moving object in a non-contact manner, identifies the moving object, and performs other functions as necessary. 1. A mobile communication system has been proposed in which information is written from a pick-up device to a transponder in a non-contact manner, and is used, for example, for mobile unit identification, room entry/exit control, and electronic coupon tickets. .

[Problem to be solved by the invention] However, in conventional systems, only the interrogator, which is a fixed station, manages the communication status and information content, and the transponder, which is a mobile station, manages the communication status and information. It was not possible to know the content of the information. For this reason, for example, when a transponder is used for mobile object identification or room entry/exit control, there is a problem in that the user cannot know whether or not his or her presence has been confirmed. Furthermore, when using a transponder as an electronic coupon ticket, there was a problem in that the user could not know the remaining number of credits or the expiration date.

The present invention has been made in view of these points, and its purpose is to provide a transponder with a display function that can inform the user of communication status and information content.

[Means for Solving the Problems 1] In the transponder with display function according to the present invention, in order to solve the above problems, as shown in FIGS. In the transponder 2, which receives the interrogation signal X in a non-contact manner from the interrogator 1 installed at the location where the mobile object M passes, and returns the response signal Y in a non-contact manner, a display section 28 for displaying internal information is provided. It is characterized by the fact that it has been provided.

[Function] In the present invention, since the transponder 2 is provided with the display section 28 for displaying internal information, the user can be informed of the communication status with the interrogator 1 and the content of the information. The internal information displayed is not particularly limited; for example, in the case of mobile object identification or room entry/exit control, a display indicating that one's presence has been confirmed or one's own identification information may be displayed. It's fine. Furthermore, in the case of an electronic coupon ticket, the number of times it has been used, the number of points remaining, the expiration date, etc. may be displayed.

Note that when the transponder 2 has a built-in clock function, it may be possible to display time information as one of the internal information.

[Embodiment] FIG. 2 shows a schematic configuration of an embodiment of the present invention. In the figure, 1 is an interrogator, which is installed at the entrance of the room. Reference numeral 2 denotes a transponder, which is attached to the mobile body M and stores unique identification information (for example, multi-digit numerical information) at 1-.

The interrogator 1 can read information from the transponder 2 and write information to the built-in memory of the transponder 2 using spatial propagation media such as light, ultrasound, and radio waves (particularly microwaves). It has become. Note that the communication area of the interrogator 1 is relatively limited, and the communication operation is performed only when the transponder 2 is present in the vicinity of the interrogator 1.

FIG. 3 is a block diagram of the interrogator 1 and the transponder 2. In the figure, X is a question signal and Y is a response signal.

In the interrogator 1, 10 is a data control/processing circuit;
12 is a modulator, 12 is a demodulator, 13 is a transmitting antenna, 14 is a receiving antenna, and 15 is a receiving amplifier. In the responder 2, 20 is a data control/processing circuit, 21 is a modulator, 2
2 is a demodulator, 23 is a transmitting antenna, 24 is a receiving antenna, 25 is a receiving amplifier, and 26 is a detection circuit for the end timing of the interrogation signal X. In addition, 27 is an operation unit, 28
is a display section, and two are buzzers.

The information communication operation between the interrogator 1 and the transponder 2 will be explained below. The information output from the data control/processing circuit 10 of the interrogator 1 is modulated by the modulator 11 and sent to the transmitting antenna 1.
3 is radiated as an interrogation signal X and sent to the transponder 2. In the transponder 2, this one-time borrowed code X is received by the receiving antenna 24, amplified by the receiving amplifier 25, and demodulated by the demodulator 22. , input to the data control and processing circuit 20. The data control processing circuit 20 performs operations according to the information contained in the interrogation signal X, and writes the information contained in the interrogation signal X into the built-in memory as necessary.

When the end detection circuit 26 detects the end of the inquiry signal A reply is sent to interrogator 1.

In the interrogator 1, this response signal Y is received by the receiving antenna 14, amplified by the receiving amplifier]5, demodulated by the demodulator 12, and inputted to the data control/processing circuit 10. The data control/processing circuit 10 reads the information contained in the response signal Y and stores it in the built-in memory as necessary.

In this embodiment, by operating the operating section 27, internal information stored in the data control/processing circuit 20 is displayed on the display section 27.
8 can be displayed. For example, in the case of an electronic coupon ticket, the displayed internal information includes the number of uses, remaining points, expiration date, etc.

In addition, in the case of mobile object identification and room entry/exit management, there is identification information, etc. Note that when the operation section 27 is not operated, time information may be displayed using a clock function built into the data control/processing circuit 20. Further, even if the operating unit 27 is not operated, the buzzer 29 may be set to sound if the internal information meets a predetermined condition. For example, in the case of an electronic coupon ticket, when the number of points remaining is running low or when the expiration date is approaching, the buzzer 29 may sound to alert the user. As a result, the user can operate the operation unit 27 to check the internal information, pay a fee, and undergo the procedure for updating the internal information before the number of points remaining is insufficient or the expiration date has expired. Furthermore, in the case of mobile object identification or room entry/exit control, two buzzers may be configured to sound when the interrogator 1 recognizes the transponder 2. This results in
Users can easily know that their passage or entry/exit has been confirmed.

FIGS. 1(a) and 1(b) are perspective views showing the appearance of the transponder 2 of the present invention. The same fM (a) is wristwatch type, the same figure (1
)) is a card type, and is small and lightweight so that users can easily carry it. Preferably, two operation units 27 are provided as shown in the figure, and each can be used as an up switch and a down switch. For example, when using it as an electronic ticket,
As shown in Figure 1 (,), time information is normally displayed, and each time the up switch is pressed, the display changes in the order of number of uses, remaining points, expiration date, identification information, and time information. Configure it as follows. Further, the display is configured so that each time the down switch is pressed, the display changes in the order of identification information, expiration date, remaining power, number of uses, and time information.

In this way, necessary information can be displayed quickly. Furthermore, when there are many items of internal information to be displayed, the first switch may be used for group search, and the second switch may be used for item search within each group.
