[0005]

However, in the above-mentioned conventional wireless communication control system, when a weak radio wave is used as a wireless signal, the practical reach is about 15 m, which is not a problem, but it has been developed in recent years. When using a small amount of power for a wireless signal that is planned for practical use,
Since the practical reach distance is extended to about 50 m, the ID numbers of other wireless transmitters operated from a distant position during the registration mode are likely to be registered in the wireless receiver. Therefore, for example, even when the wireless transmitter is operated in the adjacent house, the operation signal may be output to the lighting fixture or the like connected to the wireless receiver.

Further, since the ID number of the wireless transmitter can be registered in the wireless receiver only during a predetermined time after the power is turned on, when registering the ID number of the wireless transmitter to be newly used, The power of the wireless receiver has to be turned on again to transmit the wireless signal within a predetermined time, which is a troublesome task. The present invention has been made in view of the above circumstances, and enables a wireless transmitter to transmit a wireless signal for instructing ID number registration, and a wireless receiver registers only the ID number of the signal and It is an object of the present invention to provide a wireless communication control system that does not malfunction due to the operation of a wireless transmitter.

[0007]

In the wireless communication control system according to claim 1 of the present invention, the wireless transmitter is provided with a mode switching means, and when the mode switching means is set to the registration mode, the registration is performed. The wireless receiver transmits a wireless signal for use in the normal mode while transmitting a normal wireless signal when the normal mode is set. The wireless receiver has a mode switching means and an ID registration memory for registering the ID number of the wireless transmitter. When the mode switching means is set to the registration mode and a registration wireless signal is received from the wireless transmitter, the ID number added to this signal is registered in the ID registration memory while the normal mode is set. When a normal wireless signal is received when set to, the I added to this wireless signal Find the number from the ID registration memory, if the same ID number is registered, according to the wireless signal, and executes necessary processing.

Therefore, since the mode switching means is provided in both the wireless transmitter and the wireless receiver and the registration mode is double-locked in both the transmitter and the receiver, the wireless reception can be performed by operating the other wireless transmitters. I in the bowl
It is less likely that the D number will be registered, and subsequent malfunctions will be eliminated. Here, the mode switching means of the wireless transmitter and the receiver is switched to the registration mode when the power is turned on, and after a lapse of a predetermined time or a switch operation,
It is designed to return to the normal mode, and it is possible to switch to the registration mode by operating the switch. Further, the wireless signal for registration includes at least an ID number, and the normal wireless signal includes control information for instructing operation in addition to the ID number. Further, the ID number may be any data that can identify each wireless transmitter.

According to a second aspect of the present invention, there is provided a wireless communication control system, wherein the mode switching means of the wireless transmitter according to the first aspect includes a registration mode switch, and a predetermined time period elapses after the registration mode switch is operated. The registration mode is set. The wireless communication control system according to claim 3 is configured to be set to the registration mode when a plurality of operation switches provided on the wireless transmitter are simultaneously operated instead of the registration mode switch according to claim 2. . This wireless transmitter does not have a dedicated registration mode switch, and can be set to the registration mode by operating a plurality of existing operation switches.

According to a fourth aspect of the wireless communication control system of the present invention, the mode switching means of the wireless transmitter of the first aspect is set to the registration mode for a predetermined time after the power is turned on, and the call is transmitted during that time. The wireless signal to be transmitted becomes a registration wireless signal. According to a fifth aspect of the present invention, in the wireless communication control system according to any one of the first to fourth aspects, the wireless receiver includes a buzzer ringing means, and when the registration mode is set, the wireless transmitter transmits a wireless signal for registration. Receives the signal and stores the ID in the ID registration memory
When the number is registered, the buzzer sounding means outputs a buzzer sound.

As a result, the registration of the ID number by operating the wireless transmitter can be confirmed with a buzzer sound, and
When the wireless transmitter is not set to the registration mode and is not transmitting the wireless signal for registration,
If the buzzer sounds from the wireless receiver, it can be known that the ID number was erroneously registered by the operation of another wireless transmitter. At the time of erroneous registration, the all clear switch may be operated to delete all the ID numbers registered in the ID registration memory, or the clear switch may be operated to delete only the received and registered ID numbers.

A wireless communication control system according to a sixth aspect is the wireless communication control system according to any one of the first to fifth aspects, wherein the wireless signal transmitted from the wireless transmitter is an ID number, a registration wireless signal, and a normal wireless signal. And a signal type for distinguishing between the two types are combined with at least a plurality of bits.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a basic configuration of a wireless communication control system according to the present invention. This wireless communication control system includes a wireless transmitter 1 that transmits a wireless signal to which an ID number is added, and a wireless receiver 2 that receives this wireless signal.

The wireless transmitter 1 includes a CPU 11 for controlling the entire wireless transmitter 1, an oscillator 12 and
A multiplication unit 13, a modulation unit 14, an ID number setting unit 15 in which the ID numbers of the individual wireless transmitters 1 are preset,
Registration mode switch SW that switches from the normal mode to the registration mode as a mode switching means only for a predetermined period after the operation.
1 and so on.

The wireless receiver 2 includes a CPU 21 for controlling the entire wireless receiver 2 and a high frequency amplifier 2.
2, a frequency conversion unit 23, an IF amplification unit 24, a signal output unit 25 that outputs an operation signal via a signal line L, and an ID.
An ID number registration unit 26 that registers the ID number of the wireless transmitter 1 as a registration memory, a buzzer driver 27 that sounds a buzzer sound as a buzzer sounding means, and a mode changeover switch SW2 that switches between a normal mode and a registration mode as a mode switching means. And so on.

With such a configuration, the wireless communication control system according to the present invention operates as follows.
The wireless transmitter 1 can be set to the registration mode or the normal mode by the registration mode switch SW1, and the CPU 11 determines this mode,
When a button is operated, a wireless signal corresponding to each mode is transmitted.

When the registration mode switch SW1 is operated to set the registration mode, a wireless signal for registration is transmitted, and when the mode is returned to the normal mode, a normal wireless signal is transmitted. On the other hand, in the wireless receiver 2 which receives these wireless signals, the CPU 21
The type of the signal is determined with, and when the signal is a wireless signal for registration, the ID number added to this signal is registered in the ID number registration unit 26 so as not to overlap, and when it is a normal wireless signal, it is added to this signal. The ID number is retrieved from the ID number registration unit 26, and if the same ID number is registered, the operation signal is output from the signal output unit 25 according to the control information of this wireless signal.

However, the wireless receiver 2 side is also provided with a mode selector switch SW2 for switching the mode, and this mode limits the type of wireless signal received from the wireless transmitter 1. When the mode switch SW2 is set to the registration mode (for example, in the switch-on state), only the registration wireless signal is accepted and the normal wireless signal is invalidated. When the normal mode is set (switch off state, for example), only normal wireless signals are accepted and wireless signals for registration are ignored.

That is, if a wireless signal for registration is received during the registration mode, the ID number is registered in the ID number registration section 26, and if a normal wireless signal is received during the normal mode, the ID number is registered as the ID number. A search is performed from the unit 26, and processing according to the control information is performed. In (a) to (g) of FIG.
An example of the basic operation of the system of the present invention described above is shown in a timing chart.

Wireless transmitter 1 and wireless receiver 2
If both are in the registration mode by the registration mode switch SW1 and the mode changeover switch SW2, the ID number of the wireless signal transmitted from the wireless transmitter 1 is registered in the ID number registration unit 26 of the wireless receiver 2. (C), if both are in the normal mode, the ID of the normal wireless signal transmitted from the wireless transmitter 1.
The number is retrieved from the ID number registration unit 26, and an operation signal is output based on the control information (d).

Next, an example of the structure of the wireless signal is shown in FIG.
Shown in. In the wireless transmitter 1, the wireless signal is configured as shown and the ID number is set to the ID number setting unit 15
Read from and added, along with control information and signal type,
It transmits to the wireless receiver 2. With such a configuration, the registration wireless signal and the normal wireless signal need only have different signal type settings and have a bit configuration, so that the settings can be easily performed.

The registration of the ID number in the wireless receiver 2 can be confirmed by a buzzer sound via the buzzer driver 27. If a buzzer sound is output when a registration wireless signal is received from the wireless transmitter 1 and the ID number is registered in the ID number registration unit 26, the registration of the ID number can be confirmed and other wireless signals can be confirmed. It can be seen that the ID number was erroneously registered by the operation of the transmitter 1. That is, the wireless transmitter 1 is not operated,
Alternatively, when the buzzer sound such as “beep” sounds even though the wireless signal is transmitted in the normal mode, it means that the wrong ID number is registered. In this case, all the ID numbers may be erased, or only the incorrectly registered ID numbers may be erased and the registration may be redone.

The confirmation of this registration is not limited to the confirmation by the buzzer sound, but may be confirmed by lighting or blinking the LED or the like. Further, the mode switching means of the wireless transmitter 1 and the wireless receiver 2 is not limited to the registration mode switch SW1 and the mode switching switch SW2, which are provided for exclusive use, and a conventional switch for performing other functions may be used. The registration mode may be set when a plurality of units are simultaneously operated, for example, for a certain period of time. Furthermore, a timer provided inside the CPUs 11 and 21 may be set to a registration mode for a predetermined time (for example, 1 minute) after the power is turned on, and each time a wireless signal for registration is received during the registration mode. The predetermined time may be extended, for example, by 1 minute.

[0024]

As can be understood from the above description, according to the wireless communication control system of the first aspect of the present invention, it is possible to transmit the registration wireless signal and the normal wireless signal separately from the wireless transmitter. Therefore, the wireless receiver only needs to register the ID number of the wireless signal for registration. Also, if both the transmitter and the receiver are not in the registration mode, the ID number will not be registered in the receiver, so that the ID numbers of other wireless transmitters will almost never be registered, and subsequent malfunctions will occur. Also disappears.

According to the wireless communication control system of the second aspect, the wireless communication device is switched to the registration mode only by operating the registration mode changeover switch of the wireless transmitter, and the wireless communication is performed within a predetermined time after the operation. The ID number can be registered in the wireless receiver by transmitting the signal. According to the wireless communication control system of the third aspect, it is not necessary to provide a dedicated switch for the wireless transmitter, and it is possible to switch to the registration mode simply by operating a plurality of existing switches at the same time.

According to the wireless communication control system of the fourth aspect, when the wireless transmitter is turned on, the mode is switched to the registration mode, and if a wireless signal is transmitted before a predetermined time elapses, during that time. The transmitted wireless signal becomes a registration wireless signal, and the ID number can be registered in the wireless receiver. Therefore, it is not necessary to provide a registration mode changeover switch in the wireless transmitter. According to the wireless communication control system of claim 5, when the wireless transmitter registers the ID number of the wireless transmitter, a buzzer sound is output, so that it is possible to easily confirm the registration of the ID number. Since it can be seen that the ID number of the wireless transmitter has been erroneously registered, it is possible to take immediate action to delete the ID number. Therefore, there is no malfunction when another wireless transmitter is operated due to registration of an incorrect ID number.

According to the wireless communication control system of the sixth aspect, the wireless signal has a configuration in which a plurality of bits are combined so that the registration and the normal wireless signals can be easily set and identified. The effects of the system according to claims 1 to 5 can be obtained without significantly changing the conventional system.
