[Invention or problem to be solved]

By the way, in the conventional method of writing the ID code in advance at the factory at the time of shipment, there will be no inconvenience if there is one slave unit for one base unit, or there will be problems when there is only one slave unit for one base unit. On the other hand, inconveniences occur when there are multiple handsets, especially when the handsets are purchased later.

In other words, since the child device purchased later requires the same ID code as the parent device, it becomes necessary to write the ID code at the factory or in a similar process before selling it. , When writing ID codes to multiple handsets in advance at the factory, use the same ID code.
I had to specify the number of machines to write the D code to.

However, even if the same ID code is written to multiple units, there is a problem that not all of the units will be sold and the unit will remain in stock on the mechanical side.

Also, even if you prepare multiple handsets with the same ID code written on them, if you need more handsets than you have prepared, you can still write the ID code at the factory or There was also the problem of having to do similar work and making customers wait.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problems, and its purpose is to provide the base unit with a function to write the same ID code as the base unit to the slave unit, so that the ID code can be used as necessary. To provide a method for registering an identification number in a cordless telephone, which allows ID codes to be easily written to as many handsets as possible.

[Summary of the invention]

The identification number registration method for a cordless telephone according to the present invention is intended to achieve the above-mentioned object, and its gist is to include a memory means in which an ID code is recorded, and a data output means for sending out the memory means. Consisting of a base unit, a slave unit having data input means for inputting the ID code sent from the base unit, and memory means for storing the ID code input from the data input means, and the data output from the base unit In this identification number registration method, an ID code in a memory means of a master device is transmitted to a slave device through a data input means of the slave device and the ID code is recorded in the memory means of the slave device.

[Embodiments of the invention]

Hereinafter, an embodiment for implementing the identification number registration method in a cordless telephone according to the present invention will be described.

FIG. 1 shows a configuration for writing an ID code from a base unit to a slave unit by wire, where 1 is the base unit in a cordless telephone, and 2 is the slave unit.

The base unit 1 has a control circuit 1a that controls transmission and reception of ID codes with the slave unit 2, and an IDROM 1b that is a memory means that transmits ID codes registered in advance based on instructions from the control circuit 1a. , an input/output terminal 1 that sends an ID code to the handset 2 according to a command from the control circuit 1a.
c, an operating section 1d for controlling the control circuit 1a and outputting an ID code, and a display 1e for displaying the output status according to commands from the control circuit 1a.

The handset 2 also includes a control circuit 2a that controls transmission and reception of ID codes with the base unit 1, and a memory means into which the ID code sent from the base unit 1 is written based on instructions from the control circuit 2a. A certain I DRAM 2b and the control circuit 2
an input/output terminal 2c for receiving an ID code sent from the base unit l in response to a command from a; and an operation unit 2d for controlling the control circuit 2a to receive the ID code sent from the base unit l. , and a display 2e that displays the input status according to commands from the control circuit 2a.

Note that 3 is the input/output terminal 1c of the base unit 1 and slave unit 2.

This is a connection cable that connects 2c.

Usually, one base unit 1 and one slave unit 2 are sold as a pair, so the base unit 1 and slave unit 2 have the same ID.
The code is written in ROMlb and IDRAM2b. Here, if a child device is purchased without an ID code written therein, the user must write the ID code of the parent device 1 into the IDRAM 2b of the child device 2 by himself/herself.

The method of writing this ID code will be explained with reference to the flowchart shown in FIG.

First, the control circuits 1a and 2a of the base unit 1 and the slave unit 2 monitor whether or not the operation units 1d and 2d have been operated to write an ID code (steps Sl and S2).
. When it is determined that an operation has been performed in the control circuit 1a, the number n that was previously registered in the handset 2 is read out from the memory (step S3), and then the number n+1 to be registered in the handset 2 this time is set (step S3). S4). and,
Step S5 to display this number n+1 on the display 1e.
), it goes into standby mode.

In this state, the control circuit 1a monitors whether or not the switch for transmitting the ID code of the base unit 1 has been operated by the operating unit 1d (step S6), and if it determines that the operation has been performed, the control circuit 1a reads the ID code corresponding to n+1 from the IDROM 1b. I do
The D code is loaded (step S7), and the loaded ID code is transmitted using the connection cape 3 (step S8).

On the other hand, the control circuit 2a of the handset 2 is operated by the operation section 2d.
When it is determined that the operation for writing the D code has been performed, the mode is set to N) code writing mode (step S9).
), the ID code writing mode is displayed (sounded) (step 510). In this state, when the ID code is transmitted in step S8, the control circuit 2a of the handset 2 monitors whether or not it has received the ID code from the base device 1 (step 5ll). When it is determined that it has been received, the received N) code is stored in IDRAM2.
b (step 512).

The 1ll) code stored in this IDRAM 2b is loaded by a command from the control circuit 2a (step S
I3), the loaded ID code is connection code 3
is transmitted to base unit l via (step 514).

In addition, the control circuit 1a of the base unit 1 that has transmitted the ID code described above also determines whether the ID code transmitted from the base unit 1 and the ID code returned from the slave unit 2 match or not. A timer for time t, which determines the time at which the ID code is transmitted from base unit 1, is reset (step S15), and the timer is started (step S]6).

Then, the control circuit 1a of the base unit 1 monitors whether the time t has reached the initial setting value or has become larger than the initial setting value (step 517), and further, the control circuit 1a
monitors whether or not there is an ID code reply from handset 2 after time t has elapsed (step 518).

If there is a reply, the control circuit 1a checks whether the ID code sent from the base unit 1 and the ID code returned from the slave unit 2 match (step 519), and if they do not match after this verification In this case, the time T required for verification is the initial setting value T. Step 520), the initial setting value T
If the value exceeds 0, the process returns to step S7 and the above-described operations are repeated, and an error is displayed on the display 1e (step 521).

On the other hand, if the verification result is determined to be correct, the connection cable 3
A termination signal is transmitted to the handset 2 via the terminal (step 522). Then, the control circuit 1a assumes that the numbers n and +1 have been registered in the handset 2, and registers these values in the memory (step 523).

In addition, the control circuit 2a of the handset 2 monitors whether or not it has received a signal from the base unit 1 (step 524), and if it receives a signal from the base unit l, the received signal is Step 525), if it is not the end signal, step S
Returning to step 11, if it is determined that it is an end signal, an end display is made (step 526), and all operations are ended.

In the embodiment described above, ID codes are exchanged between the base unit 1 and the slave unit 2 via the connection cable 3, but it is also possible to perform the exchange wirelessly. Figure 3 shows what is done wirelessly.

In Fig. 3, the difference from the above-mentioned Fig. 1 is that instead of the input/output terminals 1c and 2c of the master unit 1 and slave unit 2, the control circuit 1a of the master unit 1 and the control circuit 2a of the slave unit 2 are used. The RF sections If and 2f for modulating the ID code and transmitting it wirelessly are connected, and the connection code 3 of the circuit shown in FIG. 1 is eliminated.

The operation in this circuit is shown in step S in the flowchart used to explain the operation in FIG.
8 to step Sll, the ID code from step S14 to step S18, and the ID code from step S22 to step S24 were sent via the connection cable 3. In the embodiment shown in the figure, the explanation is omitted since it is completely the same except that the communication is performed wirelessly via the RF sections If and 2f and the antennas 1g and 2g.

In addition, we used IDRAM2b, which is rewritable, as the memory means of the slave device, but in order to prevent it from being rewritten in case of theft, etc., we used E2, which cannot be rewritten.
It is also possible to use FROM.

〔Effect of the invention〕

As described above, in the present invention, the base unit has the same ID as the base unit.
By providing a function to write the code to the slave unit, you can easily write the ID code to the required number of slave units as needed, so you can register the same ID code as the base unit on the slave unit in advance. (There is no need to do this, so there is no need to worry about backlogs due to inventory. Also, even if the child device is purchased later, the user can register the same ID code as the parent device, so the user can This has the effect of allowing users to freely purchase slave units.
