Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remote control device using infrared rays or radio waves and powered by a battery.

Conventional configurations and their problems Generally, remote control devices are configured using batteries as a power source for convenience of operation. When the operated device is used in the vicinity of the operating device, such as in the same room, the remote operating device usually consists of only a transmitter. However, if the operated device is installed at a remote location where the operation cannot be directly checked by the operator, there is a drawback that if the remote control device is composed of only a transmitter, it is difficult to check the operation. To solve this problem, a method has been proposed in which a receiving section is provided in the remote control device and the operation of the operated device is sent back and confirmed.

However, with conventional configurations, remote control devices with a built-in receiver have a constant power supply, which shortens the battery life of the power source.
In addition, since the signal is received by the receiver at the time of transmission, there is a risk of erroneous recognition by the receiver.

OBJECTS OF THE INVENTION The present invention has been devised in view of the above-mentioned problems, and its object is to provide a transmitting device for transmitting and receiving, respectively, in a remote control device having a receiving function.

The purpose of this system is to reduce power consumption by switching the power supply to the receiving device and connecting the power only when performing remote control.

Structure of the Invention The present invention has a transmitting means and a receiving means for displaying the reception status, and a battery is connected to each of the power supply terminals of the transmitting means and the receiving means through first and second switch elements. A DC power supply is connected to the transmitting means, and a transmission data transfer signal line and a transmission completion detection signal line from the transmitting means are connected to the receiving means, and when a transmitting operation is performed, power is supplied to the transmitting means to the outside. After completion of the transmission, the receiving means is energized for a certain period of time, and after transmitting data is transferred to the receiving means, the power supply to the transmitting means is cut off.

DESCRIPTION OF EMBODIMENTS The present invention will be described below using an embodiment. FIG. 1 is a block diagram showing the basic configuration of the present invention, and FIG. 2 is a block diagram showing a specific example of the configuration. In FIGS. 1 and 2, reference numeral 1 denotes a group of operation buttons that the user selects and operates, and although four buttons H1a to H1d are shown in the embodiment, the number of buttons can be set arbitrarily. 2 is a transmitting means having a transmitting function.

Reference numeral 3 denotes a switch element connected in series to the power supply terminal of the transmitting means 2, which is composed of a semiconductor switch, a relay, or the like. This is a light emitting element for four-digit transmission, and although an infrared light emitting element is used in the embodiment of the present invention, it can also be configured with a wireless antenna or the like. 6 is a transmission data transfer signal line from the transmitting means 2 and a transmission completion signal line 61\-.

Although two detection signal lines are provided in the embodiment of the present invention, it can also be implemented with just one detection signal line. Reference numeral 6 denotes a light receiving element for receiving a reply signal, and although an infrared light receiving diode is used in the embodiment of the present invention, other means can be used as described above. This is a 7-digit receiving means. 8/i is a switch element connected in series to the power supply terminal of the receiving means 7. Numeral 9 is a light emitting element (LED) for displaying the reception status, and in the embodiment of the present invention, the number (9a-96) is set according to the number of transmit buttons. 10 is a light emitting element (LED) for indicating an abnormality. Reference numeral 11 is a DC power source composed of a battery.

This is an OR circuit using 12 diodes. 13 is an OR circuit composed of wired OR.

The self-holding means of the 14Vi switch element 3, 16 a transmission button discrimination means, 16 a transmission data setting means, 17 a transmission drive means, 18 a transmission completion detection means, and 19 delay means. An OR circuit composed of 20 wired ORs, self-holding means for 21 switch elements 8, 22 a delay means, 23
24ij is a storage means for transmitting data, 24ij is a reception signal detection means for the light receiving element 6, 6...-7 26 is a comparison judgment means, and 26r/'i is a display driving means.

The operation in the above configuration will be explained. In FIG. 2, when any one of the transmission buttons 1a to 1d is pressed, a voltage output is generated from the DC power supply 11 at the output of the diode OR circuit 12, and this voltage output is passed through the OR circuit 13 to the switch element 3.
is applied to the control terminal of the switching element 3, and the switching element 3 becomes conductive. When the switch element 3 becomes conductive, power is supplied to the transmitting means 2, and when the internal circuit of the transmitting means 2 becomes operational, K,
A signal is applied to the set terminal of the self-holding means 14, the self-holding means 14 self-holds, and the switch element 3 maintains the conductive state. On the other hand, by suppressing the transmission buttons 1a to 1d, the transmission button discriminating means 16 determines which button has been operated, and the transmission data setting means 16 at the next stage sets data to be transmitted, and this transmission data is transmitted to the transmission driving means. 17, a transmission signal is given to the infrared light emitting element 4, and is transmitted to the receiving section of the operated device. At this time, transmission completion detection means 1
8 does not generate a signal during transmission, but generates a signal at the output when transmission is completed. Then, transmission is completed 7-1; When a signal is generated at the output of the detection means 18, after a certain time delay determined by the delay means 19, a signal is given to the reset terminal of the self-holding means 14, and the self-holding means 14 is released. The power supply to the transmitting means 2 is cut off. However, before the power supply to the transmission means 2 is cut off, that is, at the time of completion of transmission, a signal is applied to the control terminal of the switch element 8 via the OR circuit 20 by the output signal of the transmission completion detection means 18. When the switching element 8 becomes conductive, power is supplied to the receiving means 7, and at the same time a signal is given to the cent terminal of the self-holding means 21, the self-holding means 21 self-holds, and its output is passed through the OR circuit 20 to the switch. The conductive state of element 8 is maintained. At the time when power is supplied to the receiving means 7, the transmitting means 2 is powered, and the setting data of the transmission data setting means 16 is transferred to the storage means 23 of the receiving means 7 at this time. Therefore, the transmitting means 2
The set time of the delay means 19 is set to a value longer than this data transfer time. Here, the receiving means 7 is supplied with power and is in a state where it can receive a reply signal from the operated device, and the reply signal from the operated device is received by the light receiving element 6 and amplified and detected by the received signal detecting means 24. Comparative judgment means 26
becomes the input.

The comparison/judgment means 25 compares the data of both the received signal means 24 and the storage means 23, and if a predetermined condition is met, generates an output signal.I-Display drive means 26 manually inputs, for example, the LICDea corresponding to the pressed transmission button. Light up any one of ~9d. However, if the reply signal cannot be received, for example, the LED lo will blink to indicate an abnormal condition. The time for this display is determined by the set time of the delay means 22.

The setting time of this delay means 22 is the energization time of the receiving means 7. In other words, the delay means 22 starts operating when the transmission is completed, and when the set time elapses, the self-holding means 2 starts operating.
A signal is applied to the reset terminal 1 to release the self-holding state and de-energize the receiving means 7. With the above operations, all the power supplies are returned to the cut-off state after sending, receiving and displaying replies.

FIG. 3 shows the above-mentioned operation in a flowchart, and although detailed explanation is omitted in 9, the operation basically operates according to this diagram.

Figure 4 shows the transmitting means 2 and receiving means 7 of Figures 1 and 2.
This is a timing chart showing the timing of power supply. In contrast to the operation described above, tl is the send button 1a.
-1d press operation, t2 corresponds to the time when the transmission completion detection means 18 generates the output, t3 corresponds to the time when the delay means 19 generates the output, and t4 corresponds to the time when the delay means 22 generates the output.

Effects of the Invention As described above, according to the remote control device of the present invention, the power supply to the transmitting means and the receiving means is switched.In the remote control device of the present invention using a battery as a power source, the receiving function It has the advantage of having a long battery life. In addition, since the receiving device is energized after the operation signal has been transmitted to the operated device, it is advantageous to eliminate the risk of the transmitted signal entering the receiving circuit and causing malfunction. 10 A- in a location where the operation of the operated device cannot be directly confirmed by the operator.

In such cases, the effect is a dog.
