Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certification / registration device for a communication system in which a receiver pre-registers an ID code for authenticating a transmitter during communication.

[0002]

2. Description of the Related Art In recent years, in a wireless communication system, when communication is performed between a plurality of transmitters / receivers or when a single receiver is communicated with a plurality of transmitters, communication is performed on the receiving side. It is necessary to authenticate whether the transmitter of the other party is a legitimate transmitter, and the ID code of the legitimate transmitter is authenticated and registered in advance on the receiver side. Then, during communication, the ID code transmitted from the transmitter is compared with the registered ID code,
When they match, communication is started. Therefore, it is necessary to prevent erroneous registration in the ID code registration on the receiving side.

Therefore, FIG. 3 shows a block diagram of a conventional authentication registration apparatus. FIG. 3 shows a transmitter 12 and a receiver 13 in the communication system 11, and the receiver 13 includes a demodulator 14, a microcomputer 15, a registration memory 16, and a display 17 as a configuration for performing authentication registration. At the same time, the registration switch 18 for performing the registration operation is connected to the microcomputer 15. Also, transmitter 1
2 transmits the ID data including the ID code to the receiver 13 so that the receiver 13 registers the unique ID code of the transmitter itself.

Therefore, FIG. 4 shows a flowchart of conventional authentication registration. In FIG. 4, first, the registration switch 18 is turned on on the receiver 13 side (step (S)).
1) In this state, the transmitter 12 transmits ID data including a unique ID code (S2). On the receiver 13 side, the received ID data is demodulated by the demodulator 14 and sent to the microcomputer 15, and the ID code is registered in the registration memory at an address predetermined by the microcomputer 15 (S3).

Then, the microcomputer 15 uses the I
When the registration of the D code in the registration memory 16 is completed, a signal to that effect is output to the display unit 17 for reception display (S4).

[0006]

However, in an environment in which a plurality of transmitters 12 exist with respect to a receiver 13 that registers an ID code, ID codes of transmitters other than the corresponding transmitter 12 are registered in a registration memory. There is a problem in that, when the registration is erroneously registered in 16, the configuration cannot be individually corrected. That is, although individual ID codes can be sequentially registered in the registration memory 16, the individual ID codes cannot be erased, and a method of erasing the entire ID code is adopted. Therefore, if the entire device is erased, the correctly registered ID code is also erased, and re-registration is required, which is a problem. In addition, since the operation is kept as it is after the registration is completed, there is a risk that another transmitter may perform an unintended operation as it is.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide an authentication registration device for a communication system for preventing erroneous registration of ID codes in a plurality of transmitters.

[0008]

In order to solve the above-mentioned problems, in the first aspect of the present invention, there is provided an authentication registration device of a communication system, comprising: a predetermined receiving means for registering a unique identification code of a predetermined transmitter. The receiving means corresponds to an operating means for performing an operation for registering the identification code, a first storage means for temporarily storing the received identification code, and an identification code stored in the first storage means. Second storage means for registering the identification code stored in the first storage means, which is transferred by the operation of the operation means after it is confirmed that the transmitter is authentic. An authentication registration device of a communication system is configured to have a control means for controlling the storage of the identification code in the first storage means, the transfer to the second storage means, and the registration according to the operation means. To be done.

According to a second aspect of the present invention, the control means according to the first aspect stores the memory before the first memory means in response to the operation of the operating means when the identification code is stored in the first memory means. Update by deleting the contents. As described above, in the invention of claim 1 or 2, the identification code received by the control means is appropriately updated and temporarily stored in the first storage means according to the operation of the operation means, and the identification code of the corresponding transmitter is used. After it is confirmed that there is such information, it is transferred to the second storage means in accordance with the operation of the operation means to be registered normally. As a result, erroneous registration is prevented by confirming the stored content of the identification code in the first storage means and then normally registered in the second storage means, and it is possible to avoid complication due to erroneous registration. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a configuration diagram of an embodiment of the present invention. FIG. 1 shows a transmitter 2 in a communication system 21.
2 is a configuration diagram corresponding to the authentication registration of the authentication registration device 23 including 2 and receiving means. In FIG. 1, the transmitter 22 includes an ID code memory 31, a microcomputer 32, and a modulator 33, and also includes a transmission switch 34 for transmission.

An ID code memory 31 in the transmitter 22
The ID code, which is an identification code unique to the transmitter 22, is stored in advance, and the microcomputer 32 reads the ID code according to the transmission switch 34, modulates it with the modulator 33, and then receives it as ID data as the receiver. 23.

On the other hand, the authentication registration device 23 includes a demodulator 41,
A microcomputer 42 as a control means, a first memory 43 as a first storage means, a second memory 44 as a second storage means, and a display 45 are provided, and a registration switch 46 as an operation means is provided. Prepare

The demodulator 41 in the authentication registration device 23 is
The received ID data is demodulated and the ID code is sent to the microcomputer 42. The first memory 43 temporarily stores the received ID code, and the second memory 44
Is to register the ID code normally. Indicator 45
Mainly displays the ID code stored in the first memory 43 when the ID code is received. The registration switch 46 mainly stores the ID code in the first memory 43 temporarily or in the second memory 43. An operation for transferring and registering the ID code in the first memory 43 to the microcomputer 44 is performed on the microcomputer 42.

It should be noted that the first memory 43 is updated to the one in which the previously stored contents are received according to the instruction of the microcomputer 42 by the operation of the registration switch 46 at the time of storage. If the transmitter 22 is a transceiver having a receiving function, it has the configuration of the authentication registration device 23 in the figure (the microcomputer can also be used). Similarly, when the authentication registration device 23 is a transceiver having a transmission function,
The transmitter 22 shown in the figure is provided (the microcomputer is also used).

Therefore, FIG. 2 shows a flowchart of the authentication registration of FIG. In FIG. 2, first, the registration switch 46 is turned on in the receiver 23 (S11). When the transmission switch 34 of the transmitter 22 is pressed, the ID code read from the ID code memory 31 is transmitted to the modulator 33.
Is modulated and transmitted as ID data (S12).

On the authentication registration device 23 side, the received ID data is demodulated by the demodulator 41 and sent as an ID code to the microcomputer 42, and the ID code is stored (temporarily registered) in the first memory 43 ( S13). Therefore,
When the ID code stored in the first memory 43 is received, the microcomputer 42 sends a signal to the display unit 45 to display (light up) to that effect, and the transmitters other than the corresponding transmitter 22 are displayed. If it is a thing, a display to that effect is displayed on the display 45 (blinking). That is, it is determined whether or not the display 45 indicates that the ID code of the transmitter 22 is stored in the first memory 43 by the operation of the transmitter 22 (S14).

When a different ID is received on the display unit 45, it is determined that the temporary registration in the first memory 43 has failed, and the transmitter 22 is operated to display a different ID again. The registration switch 46 is turned on, and the ID data is transmitted from the transmitter 22 (S15). At this time, the first memory 43 is erased from the previous contents stored when the registration switch 46 is turned on, and a new ID code is stored and updated (S16). This is repeated until a display is made on the display 45.

Then, the transmitter 45 is displayed on the display 45.
After the display indicating that the ID code of is stored (temporary registration) is displayed, the registration switch 4
When 6 is turned on (S17), the microcomputer 42 reads the ID code stored in the first memory 43, transfers it to the designated address in the second memory 44, stores it in the memory, and performs regular registration. It is something (S1
8).

By thus storing the received ID code once in the first memory 43, the authenticity of the stored ID code in this state is confirmed, and the authentic ID is also verified.
By updating the code until the code is stored in the first memory 43, it is possible to reliably perform regular registration in the second memory 44 and prevent erroneous registration.

Returning to FIG. 1, the ID code properly registered in the second memory 44 is the ID code from the transmitter 22 and the second memory 4 in response to the communication request from the transmitter 22.
The ID code read from No. 4 is compared with each other, and when they match each other, mutual communication is possible.
