In this device, a sensor 11 or a mobile or fixed transmitter 6 provided with an operation switch
When the operation information of the operation switch 12 is transmitted to the receiver 2 as an optical wireless signal X, the optical wireless signal X is received by the light receiving element 13 as shown in FIG. The electric signal is amplified by an amplifier 7, detected and demodulated by a detection circuit 8, shaped by a waveform shaping circuit 9, sent to a controller 4 via a transmission line 3 as a wired transmission signal, and transmitted by the controller 4. Signal
The identification is performed by a recognition / decoding circuit 10 including a CPU or the like, and the controlled device 5 is controlled based on the identification content. The above device transmits an optical wireless signal X from a transmitter 6 fixedly installed at the time of installation of the device, and the transmission of the optical wireless signal is good by observing the operation state of the controlled device 5 actually controlled by the controller 4. It was checking whether or not.

[Problem to be Solved by the Invention] However, in a room, the light transmission space is changed due to the movement of an object, the installation of the curtain Y, and the like, compared to the initial installation. Due to this change, signal transmission may not be performed properly in some cases.

In this case, there is a problem that the reception (light reception) level in the receiver 2 is reduced and the controller 4 cannot discriminate the information signal from the transmission signal from the receiver 2 at this time. Of course, when the receiver 2 identifies the transmission signal and transmits the identification information to the controller 4, the identification information cannot be transmitted from the receiver 2.

The present invention has been made in view of the above-described problems, and when the level of an optical wireless signal received by a receiver is below a certain value, the controller determines that the level is abnormal, performs an abnormality display on the controller, and displays the signal content. It is an object of the present invention to provide a remote control device capable of performing an indistinguishable display separately from an abnormal display when the identification is impossible, and allowing the user to recognize an abnormality in the transmission space by both displays.

Means for Solving the Problems The present invention provides one or more transmitters for transmitting the output of an input means such as a sensor or a switch as a wireless signal, and receives and converts the wireless signal of the transmitter into an electric signal. And one or more receivers for transmitting the electric signal, and a controller for receiving the electric signal from the receiver, identifying input information from the input means based on the received signal, and performing a corresponding control. The receiver is provided with a comparison circuit for comparing and judging the level of the reception level of the wireless signal, and when the reception level of the wireless signal is lower than a predetermined value, a function of sending an abnormal signal to the controller is provided. A display means for performing an indistinguishable display when input information cannot be identified by a signal; and a display means for performing an abnormal display when the abnormal signal is input. The above transmitter periodically transmits a dummy wireless signal, receives the dummy wireless signal by the receiver, sends the reception level data to the controller, and constantly displays the reception level on the controller. is there.

[Operation] According to the present invention, if the reception level of the wireless signal transmitted from the transmitter is below a certain level, the wireless signal is displayed as abnormal by the controller, and if the information of the received signal cannot be identified, identification is not possible. It is displayed as possible, and by these two displays, it is possible to make the user surely recognize the abnormality caused by the change of the transmission space due to the environmental change and the inability to identify the information.

The one or more transmitters periodically transmit a dummy wireless signal, receive the dummy wireless signal at the receiver, send the reception level data to the controller, and constantly display the reception level at the controller. It is possible to constantly monitor the state of the transmission space.

EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 shows an overall configuration diagram of the controller 4.
Has an indistinguishable display section 15 and an abnormal signal display section 14. FIG. 2 shows an internal circuit configuration of the receiver 2 and the controller 4. The receiver 2 has a light receiving element 13 for receiving the optical wireless signal X from the transmitter 6, and an electric signal converted by the light receiving element 13. It is the same as the conventional example in that it comprises an amplifier 7 for amplifying a signal, a detection circuit 8 for detecting and demodulating the signal amplified by the amplifier 7, and a waveform shaping circuit 9 for shaping the waveform of the demodulated signal. In the present embodiment, the signal amplified by the amplifier 7 is input to the comparison circuit 16 to make a comparison judgment at a predetermined constant level, and to output an abnormal signal when the signal is lower than the predetermined level.

On the other hand, the controller 4 receives the signal whose waveform has been shaped by the above-described waveform shaping circuit 9 via a transmission line, and has a recognition / decoding circuit 11 capable of identifying input information from the received signal. Controlled device 5 based on
Is controlled in the same manner as in the conventional example, but when the input information cannot be identified, the information is displayed on the unidentifiable display unit 15, and when an abnormal signal is input, the abnormality is displayed on the abnormal display unit 14. ing.

When the transmission space changes and the reception level of the optical wireless signal X from the transmitter 6 is lower than a predetermined reference level, the comparator 16 outputs an abnormal signal.

In the controller 4 to which the abnormality signal has been input, the recognition decoding circuit 10 drives the abnormality display unit 14 based on the input of the abnormality signal to display the abnormality. If the recognition / decoding circuit 10 cannot recognize the input information from the waveform-shaped transmission signal, the non-recognizable display unit 15 displays the non-recognizable information.

Therefore, when the reception information of the receiver 2 cannot be recognized, the information is displayed on the non-recognizable display unit 15, and when the reception level is reduced due to a change in the transmission space, the abnormality is displayed on the abnormality display unit 14. If the reference constant level is set to a level at which incompatibility always occurs at this level, a display is also performed on the indistinguishable display section 15. It is recognized that the position needs to be changed to a position where both displays are turned off.

When the recognition / decoding circuit 10 is provided in the receiver 2, a signal for identifying an abnormality and a normal state is transmitted, and the controller 4 identifies the controlled device 5 with a normal signal. May be displayed.

The dummy optical wireless signal X is periodically transmitted from the transmitter 6.
Since the transmission space is transmitted and the state of the transmission space is verified, the reception level at the receiver 2 is displayed on the controller 4 and the current reception state other than the abnormal display and the unrecognizable display is displayed by the user. Can be recognized.

Although the wireless signal uses an optical signal, it goes without saying that the same configuration as described above can be used for a radio wave.

[Effects of the Invention] The present invention provides one or more transmitters for transmitting an output of an input means such as a sensor or a switch as a wireless signal, and receives a wireless signal from the transmitter, converts the wireless signal into an electric signal, and converts the electric signal into an electric signal. And one or more receivers for transmitting an electric signal, and a controller for receiving an electric signal from the receiver, identifying input information from the input means based on the received signal, and performing a corresponding control, and the receiver includes: A comparison circuit for comparing the level of the reception level of the wireless signal is provided. When the reception level of the wireless signal is lower than a predetermined value, a function of sending an abnormal signal to the controller is provided. Display means for performing an indistinguishable display when the signal cannot be identified, and display means for performing an abnormal display when the abnormal signal is input. If the reception level of the received wireless signal is below a certain level, it can be displayed as abnormal, and if the information of the received signal cannot be identified, it can be displayed as indistinguishable. Therefore, it is possible to ensure that the user can recognize an abnormality due to the change of the information or a time when the information cannot be identified, thereby improving the reliability of transmission.

Further, one or more transmitters periodically transmit a dummy wireless signal, receive the dummy wireless signal at the receiver, send reception level data to the controller, and constantly display the reception level at the controller. Therefore, there is an effect that the state of the transmission space can be constantly monitored.
