Field of the Invention The present invention relates to a wireless data transmission system using radio waves, in which an operating device for switching the operation of a load carries out an intermittent reception operation and is provided with a display means for displaying the operating condition of the load. The present invention relates to a method for surely recognizing the operating condition of a load with this operating device.

容易に行えた。2. Description of the Related Art A method of using a switch is generally used to control the operation of a load such as a lighting fixture. In this case, the switch is often installed in a place close to the load, and the person who operates the load can easily recognize the operating condition of the load (in the case of a lighting device, the lighting state or the unlit state). Further, even when the load and the switch are separated from each other, since they are connected by wire, it was possible to easily know the operating condition of the load on the switch side.

範囲で負荷の動作制御が行われることになる。By the way, recently, a system for controlling a load by using a wireless data transmission system using light has been provided. In this case, the location of the operating device (which may be portable) is limited to the range where light can reach. For example, if there is a shield that blocks light between the operation device and the control device arranged on the load side, the load operation cannot be controlled. Therefore, in the case of this system,
Similar to the case of the switch, the load operation control is performed within a range where the load operating condition can be easily understood.

示させる必要がある。However, in the case of the wireless data transmission system using light as described above, the operable range is limited. Therefore, a system using a wireless data transmission method using radio waves is provided. In the case of a wireless system using this radio wave, a battery is often used as a power source of the operating device. Therefore,
It is necessary to take measures to extend the life of this battery. As this means, for example, there is a method of performing so-called intermittent reception in which the reception function is operated intermittently. Further, in such an operating device, the operation control of the load may be performed from a place where the line of sight cannot be seen. Therefore, it is necessary to display the operating condition of the load on the operating device side.

It is conceivable to add a signal indicating the operation status of the load to the K signal and return the signal. However, in this type of system, since the plurality of operating devices are separate devices and each operates independently, the intermittent receiving cycle of each operating device is different. Therefore, there is a problem that all the operating devices are not ready to receive during the return period of the ACK signal, and the reliable return of the monitoring data cannot be performed.

It is to provide a wireless data transmission method.

Since the control device 2 does not receive the control data from (hereinafter referred to as the operating device 3 2 ), the operating condition of the load 1 is not accurately displayed on the display element 5 of the operating device 3 2 . To be able to accurately display the operation status of the load 1 in the display device 5 of the operating apparatus 3 2, 4 from the operation device 3 2
The control data E is transmitted as shown in (c). When the control data E in this case is received, the control device 2 receives the load 1
