  Next, the operation and action of the wireless communication device will be described.

  First, when the user turns on or turns off the lighting device 7 from outside the house, a command for turning on or off is transmitted from a mobile phone or the like. The turn-on or turn-off command reaches the in-home wireless master device 8 through the external communication network 11 and is transmitted to the wireless slave device 1 by radio wave communication.

  The infrared signal output device 2 of the wireless slave device 1 converts an instruction to turn on or off into an infrared signal and outputs the infrared signal to the lighting device 7. The illuminance detection means 3 measures the illuminance after a certain time after the lighting device 7 is turned on or off before and after the output of the infrared signal. In the present embodiment, the illuminance detection means 3 uses an optical sensor. When the remote control result determination means 4 compares the above two illuminances, if the illuminance increase exceeds a certain value when the lighting command is given, and if there is a illuminance decrease above a certain value when the extinction command is issued, the remote control result judging means 4 Is determined to be a failure. The remote control result reporting means 5 transmits this determination result to the external device 12 such as a mobile phone of a user outside the home through the wireless transceiver 6 and the wireless master device 8.

The remote control result notifying means 5 does not notify the user when the remote control of the lighting device 7 is successful. Report only if it fails. As a result, the user can reliably determine that the remote control has succeeded unless there is a failure report, and can suppress battery consumption.

(Embodiment 3)
Next, a radio communication apparatus according to Embodiment 3 of the present invention will be described.

  In the present embodiment, the remote control result determination means 4 determines that the control has failed only when the illuminance does not change before the lighting remote control and after a certain period of time, and when the illuminance does not exceed a certain illuminance. It is.

  In this way, the remote control result determination means 4 compares the illuminance before the infrared signal output and after a certain time after the output, and if there is no increase in illuminance above a certain value at the time of the lighting command, the illuminance after the output is Remote control fails only when the value is below a certain value. As a result, it is possible to prevent erroneous determination as failure when the lamp is lit from the beginning.

(Embodiment 4)
Next, a radio communication apparatus according to Embodiment 4 of the present invention will be described.

  In the present embodiment, the remote control result determination means 4 is configured not to determine that the control is unsuccessful in the case of the extinction control when there is no change in illuminance before the extinction remote control and after a certain time. .

  As described above, it is possible to prevent erroneous determination as failure when the light is turned off from the beginning or when the installation location of the lighting device 7 is a bright room in the daytime. In this case, the failure cannot be detected at the time of the turn-off command, but the failure of the wireless slave device 1 or the lighting device 7 is dealt with by detecting at the time of the next turn-on command. Alternatively, if it can be confirmed that the installation location is not affected by anything other than the lighting device 7 (for example, there is no window or is small), as in the case of lighting control, the remote control fails only when the illuminance after the infrared signal output is a certain value or more. It is also possible to change the operation setting.

(Embodiment 5)
Next, a radio communication apparatus according to Embodiment 5 of the present invention will be described.

  In the present embodiment, the remote control result determination means 4 updates the constant illuminance determination value at the time of lighting remote control to an optimum value depending on the installation location based on the illuminance value after the successful lighting remote control in the past. It is what I did.

  In this way, by updating the illuminance determination value to the optimum value, the accuracy of the remote control result determination is further improved, and erroneous determination can be prevented.

(Embodiment 6)
Next, a radio communication apparatus according to Embodiment 6 of the present invention will be described.

  In the present embodiment, the infrared signal output device 2 tries to control by transmitting an infrared signal again when there is no change in illuminance before remote control and after a certain time.

  In this way, by transmitting the infrared signal again and attempting the control, and re-outputting when a part of the infrared signal is missing, the failure of the remote control can be reduced. Even when compared with a similar device that always outputs a plurality of times, it is output again only when there is a possibility of failure, so that power consumption can be suppressed, which is effective for battery driving.

  As described above, in the wireless communication device according to the present invention, when a user in a remote place turns on or turns off the lighting for the purpose of crime prevention measures at the absence home, the lighting is turned on or off without fail. Therefore, the present invention can be applied to all home network systems that remotely control home devices.
