線通信装置を供給できる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device provided with a remote controller. 2. Description of the Related Art A conventional radio communication device for a device equipped with a remote controller is used for communication from the device body to the remote controller.
A communication signal whose length is defined by the Radio Law shown in FIG. 5 was output from the appliance body. As shown in FIG. 5, the remote controller has a reception standby time at which communication can be performed at regular intervals, and when the remote controller catches a preamble signal indicating the start of communication from the appliance body during the reception standby time,
The remote controller received and processed the synchronization signal indicating the beginning of the data signal included in the communication signal from the appliance body, the data signal, and the check signal for checking whether the data signal was blurred due to an external factor. . Here, the conventional remote controller has a long reception standby time of the remote controller in order to reliably catch the preamble signal from the instrument body (R time in FIG. 7). [0003] However, in the conventional radio communication device of a device equipped with a remote control device, the reception standby time of the remote control device is set so as to reliably catch a preamble signal from the device main body. The battery life is short due to the long power consumption of the remote controller consumed during this time. An object of the present invention is to solve the above-mentioned problems and to provide a wireless communication device having a remote controller with low power consumption. [0005] In order to achieve the above object, a wireless communication apparatus provided with a remote controller according to the present invention comprises an apparatus for transmitting radio equipment.
The communication signal configuration from the receiver follows the preamble signal
By shortening the operation control signal to be transmitted,
Extend the communication period of the preamble signal and
The reception period of the actuator controller is equivalent to the extended communication period
By shortening by the following period,
It has a remote controller that increases the chances of receiving a reamble signal . According to the present invention, the power consumption of the remote controller at the start of communication for receiving and displaying information such as the operating state of the appliance main body is suppressed by the above-described configuration. An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a wireless communication device provided with a remote controller according to the present invention controls a normal operation of the main body of the device, and has a longer preamble signal and a shorter data signal for the remote controller. An appliance control unit 1 for outputting an electric signal;
An appliance that converts an electric signal from the appliance control unit 1 into a radio signal and transmits it to a remote controller, or that receives a radio signal from the remote controller, converts it into an electric signal, and outputs it to the appliance control unit 1 The appliance main body having the transmission / reception unit 2 controls the normal operation of the remote controller, outputs an operation state signal for informing the user of the operation state of the appliance to the remote controller display unit, or is transmitted from the appliance main body. A remote controller control unit 3 for generating and controlling a reception standby time of a remote controller for receiving a preamble signal at a constant cycle and outputting an electric signal to the appliance body; A remote controller transmitter / receiver 4 for converting a credit electric signal into a radio signal and transmitting it to the appliance main body, or receiving a radio signal from the appliance main body, converting the electric signal into an electric signal, and outputting the electric signal to the remote controller controller 3; The remote control unit And a remote controller having a remote controller display unit 5 for displaying the operating state of the instrument to inform the user the contents of the operation condition signal from. Next, a communication method between the instrument body and the remote controller will be described. As shown in FIG. 2, the signal configuration of the communication signal, the total length of the communication signal, and the length of the synchronization signal indicating the start of the data signal are defined by the Radio Law. The communication between the appliance body and the remote controller starts when the remote controller catches a preamble signal indicating the start of communication from the appliance body when the remote controller is in the reception standby time. Therefore, as the timing at which the preamble signal is synchronized with the reception standby time of the remote controller increases, the communication between the appliance body and the remote controller is more reliably performed. Next, the operation of the above configuration will be described.
When communication is performed from the appliance body to the remote controller, the appliance control unit 1 outputs a communication signal having a longer preamble signal unit and a reduced data signal unit indicating the content of data to be transmitted as shown in FIG. Is input to the appliance transmitting / receiving unit 2. Then, the electric signal is converted into a radio signal by the appliance transmitting / receiving unit 2 and output. On the other hand, in the remote controller, as shown in FIG. 3, the remote controller controller 3 shortens the reception standby time as compared with the related art. As shown in FIG. 7, assuming that the preamble time of the conventional remote controller is T and the reception standby time is R, the effective communication interval for successful communication between the device body and the remote controller is T + R. As shown in FIG. 4, in the remote controller of the present embodiment, the preamble time can be increased by ΔT by reducing the data amount of the data signal included in the transmission signal from the main body by the shortened data signal. Therefore, the preamble time becomes T + ΔT. The reception standby time is R-ΔR which is shorter than the conventional one by ΔR. Therefore, the effective communication interval is T
+ ΔT + R−ΔR. Here, when △ T> △ R, the power consumption of the remote controller for standby for reception is saved in proportion to △ R, and the reception chance is (T + △ T).
+ R- △ R)-(T + R) = (△ T- △ R). When the remote controller transmitting / receiving unit 4 catches a preamble signal from the appliance body during the reception standby time of the remote controller, the remote controller transmitting / receiving unit 4
It receives a synchronization signal, a data signal, and a check signal, converts a radio signal into an electric signal, and outputs the electric signal to the remote control unit 3.
Then, the remote controller control unit 3 processes the data signal. As described above, even if the reception standby time of the remote controller is shortened, the timing at which the preamble signal is synchronized with the reception standby time of the remote controller is reduced by increasing the length of the preamble signal by ΔT. Without changing the reception standby time of the remote controller to △ R (<
It is possible to provide a wireless communication device including a remote controller that can be shortened by ΔT) and consumes low power. If the microcomputer and the remote controller transmitter / receiver units 2 and 4 actively reduce the data signal, the above-described effects can be obtained without reducing the amount of data to be transmitted as a data signal. As described above, the radio communication apparatus for a device provided with a remote controller according to the present invention has a long preamble signal to the remote controller and outputs a shortened data signal. And a remote controller having a remote control unit having a short reception standby time of a remote control for receiving a preamble signal transmitted from the device main body, thereby shortening the reception standby time. It is possible to provide a wireless communication device equipped with a low-power-consumption remote control device that saves power in proportion to minutes and increases the chances of reception by the remote control device.
