Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a remote control system, and in particular,
The remote control unit can be applied to a plurality of controlled electronic devices.

[Prior Art] A system remote control unit, such as a learning remote control unit, that can control a plurality of controlled electronic devices with one unit has been proposed. If the electronic devices controlled by such a system remote control unit are of different types, in many conventional cases, the operation to specify the operating mode is immediately executed without performing the operation to specify the electronic device during control operation. Just do it.

However, there are cases where it is desired to control the same type of electronic equipment by the same remote control unit. For example, due to the widespread use of electronic devices, a user may own two or more electronic devices of the same type, or a store may display two or more of the same type of electronic devices for display purposes.

In such a case, simply instructing the operating mode will cause all of the plurality of electronic devices of the same type to operate, making it impossible to control the electronic devices individually.

Therefore, in the past, different identification codes (hereinafter referred to as ID codes) were assigned to electronic devices controlled by the same remote control unit, and after identifying the electronic devices using these ID codes, the operating mode was instructed. is being done. Conventionally, an ID code has been assigned to an electronic device using a dip switch provided on the back of the electronic device.

[Problems to be solved by the invention] However, dip switches occupy space and have the problem of increasing the size of the configuration.If the number of switches is reduced in order to reduce the size, the maximum number of settings is limited. There is a problem that In addition, to avoid unnecessary and erroneous changes to the ID code, it is usually placed in a location that makes it difficult to operate, such as on the back, and as a result, the operation of setting and changing the ID code is complicated. There is a problem with becoming.

The present invention has been made in consideration of the above points, and does not require a particularly complicated configuration, allows easy ID code setting operations, and is limited to a small number of electronic devices. The aim is to provide a remote control system that will never cause problems.

[Means for Solving the Problem] In order to solve the problem, in the present invention, a remote control signal consisting of an identification code and an operation mode code of the controlled electronic device is output from the remote control unit, and the identification code is assigned In a remote control system in which a controlled electronic device is configured to execute an instructed operation mode, the remote control unit includes a code capturing means for capturing an identification code to be set, a code for instructing the setting operation, and the captured identification code. A remote control is provided with a setting identification code sending means for forming and sending a remote control signal, and also includes an identification code storage means for storing an identification code in a controlled electronic device, and a code for instructing a setting operation. An identification code storage control means is provided which causes the setting identification code inserted in the remote control signal to be stored in the identification code storage means when the signal is received.

[Function] The code capturing means in the remote control unit captures the setting identification code input by the user after instructing the setting mode when attempting to set, and the setting identification code sending means receives the code instructing the setting operation and the captured identification code. A remote control signal is formed and sent to the target controlled electronic device.

The controlled electronic device is provided with an identification code storage means for storing an identification code, and when the identification code storage control means receives a remote control signal containing a code instructing a setting operation, the identification code storage control means stores the identification code. The setting identification code inserted into the remote control signal is stored in the identification code storage means.

After setting such an identification code, the remote control unit outputs a remote control signal consisting of the identification code and operation mode code of the controlled electronic device,
The controlled electronic device to which the identification code is assigned executes the instructed operating mode.

Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 shows the remote control unit 1 of this embodiment.
0, and FIG. 2 shows the controlled electronic device 20 of this embodiment.

In FIG. 1, the key matrix means 11 is equipped with various keys (such as a numeric keypad) for specifying an ID code and operation mode as in the conventional system, and in addition, it is equipped with an ID setting for setting an ID code. It includes a setting mode start key 11a for starting mode processing, and a setting mode end key 11b for ending the setting mode.

A key signal from the key matrix means 11 is given to a control means 12 constituted by a microcomputer. The control means 12 controls the key matrix means 1 when controlling the operation mode of the controlled electronic device 20 according to a program stored in a built-in program memory section (not shown).
The ID code and operation mode code inputted via 1 are assembled into a remote control signal according to a predetermined transmission format, and the signal is sent to the transmission means 13.

Further, in the ID code setting mode, a remote control signal including the setting mode and the designated ID code is given to the transmitting means 13. Note that the control means 12 stores the following information in the internal code memory section 12a.
The set ID code is stored.

The transmission format during operation mode control is, for example, as shown in FIG. 3, consisting of an ID code, an operation mode code, a complementary code of the ID code, and a complementary code of the operation mode code.

The transmitting means 13 modulates the remote control signal given from the control means 12 for transmission, whether it is a remote control signal related to the control of the operation mode or a remote control signal related to the ID code setting mode. A modulated remote control signal (for example, an optical signal) is sent to a transmission path (for example, a mere space for an optical signal).

The controlled electronic device 20 includes a receiving means 21 .

The receiving means 21 provides the received modulated remote control signal to the demodulating means 22. For example, if the applied modulated remote control signal is an optical signal, it is subjected to photoelectric conversion, filtered and amplified, and then provided, and if it is applied from a wired transmission line, it is simply amplified and provided as an R wave.

The demodulation means 22 demodulates the modulated remote control signal, returns it to a coded remote control signal, and supplies it to the control means 23 having a microcomputer configuration.

The control means 23 supplies the included ID code to the ID code storage means 24 when the applied remote control signal is related to the ID code setting mode. The ID code storage means 24 is a non-volatile memory and stores a given ID code. Control means 2
3 also determines whether the inserted ID code is an ID code assigned to the controlled electronic device 20 when the given remote control signal is a remote control signal related to control of the operation mode. It is confirmed based on the ID code stored in the code storage means 24, and when it is confirmed, the operation mode code is given to the execution means 24.

The execution means 24 executes an operation mode according to a given operation mode code.

Next, the ID code setting process for the controlled electronic device 20 will be explained with reference to the flowcharts of FIGS. 4 and 5.

First, the processing on the remote control unit 10 side will be explained. When the setting mode start key 11a is pressed, the control means 12 starts the process shown in FIG. It is stored in the memory, and then it is determined whether the setting mode end key 11b has been pressed (steps SPI to 5P3).

As a result, if it is determined that the setting mode end key 11b has not been pressed, the process returns to step SPI described above to import the next numeric keypad code.Such processing is repeated to capture one or more numeric keypad codes. In this state, when the setting mode end key 11b is pressed, the numeric keypad code string input until this pressing is returned to the specified ID.
It is stored as a code in the code memory section 12a (step 5P4).

Thereafter, the control means 12 forms a remote control signal including a code indicating that the mode is the ID code setting mode and the input ID code, and supplies it to the transmitting means 13 to transmit the remote control signal. The process is ended (step SP5.5P6).

At this time, the user must ensure that the transmitted remote control signal is transmitted only to the intended controlled electronic device 20.For example, when transmitting by optical signal, the user must The remote control unit 1 is connected to the light receiving section of the controlled electronic device 20 so that the optical signal from the remote control unit 10 reaches only the light receiving section (receiving means 21) of the controlled electronic device 20.
It is necessary to bring 0 close together.

Next, the setting process on the controlled electronic device 20 side will be explained. If the remote control signal given from the demodulator 22 includes a code instructing the setting mode, the control means 23 starts the process shown in FIG. 5 and reads the ID code contained in the remote control signal. and gives it to the ID code storage means 24 to store the ID code and complete a series of setting processes (step 5 PIO
1SP11).

Such an ID code is used to identify the controlled electronic device 20.
The operation mode is controlled, and the control of this operation mode is almost the same as the conventional one. That is, after inputting the ID code, a desired operation mode key may be pressed. In addition, the ID entered by the remote control unit 10
The difference is that the code is sent after confirming that it is one of a plurality of ID codes stored in the code memory section 12a.

Therefore, according to the embodiment described above, the user can set the ID code for the controlled electronic device 20 using the remote control unit 10, and the operability is improved compared to the prior art. Furthermore, since the configuration of the setting process is executed by the control means 12.23 having a microcomputer configuration in both the remote control unit 10 and the controlled electronic device 20, the configuration is not complicated compared to the conventional configuration.

In addition, although the case where an ID code is used to separately control electronic devices of the same type has been described above, the present invention can also be applied to a system that targets only electronic devices of different types.

Further, in the above embodiment, the remote control unit 10 also stores the set ID code, but the remote control unit 10 also stores the set ID code.
The storage memory section for the ID code of 0 may be omitted.

[Effects of the Invention] As described above, according to the present invention, an operation for setting an identification code is performed on a remote control unit, and the identification code to be set is transmitted from this remote control unit to a controlled electronic device. Since the identification code is set on the controlled electronic device, the operation for setting the identification code is simple, and the degree of freedom in the length of the identification code that can be set is increased, and the configuration can be made larger. You can get no remote control system.
