Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a signal transmitting device for a wireless remote control, and more particularly to measures to reduce consumption of its built-in battery.

(Prior Art) Conventionally, in a signal transmitting device for a wireless remote control, for example, as disclosed in Japanese Unexamined Patent Publication No. 61-256141, when an operation key is operated, a signal corresponding to the operation key is transmitted from an infrared light emitting element. It is being sent wirelessly to the main unit.

(Problem to be Solved by the Invention) However, in the conventional device described above, a signal is transmitted each time an operation key is operated. Each operation key has a specific set temperature (for example, each one is 24℃, 25℃, 26℃...
), if one operation key (e.g. 25°C) is operated, another operation key (e.g.
26℃) to change the target value, a command signal (25℃ command signal and 26℃ command signal) will be output every time the operation key is operated, and as a result, the signal control If a battery provided in the unit is used as an internal power source, there is a drawback that the battery consumption is proportional to the number of operations of the operation key, and the battery consumption is large. The above applies not only to the case where a plurality of operation keys are provided, but also to the case where, for example, the target temperature value is changed by 1° C. each time the operation key is operated and is finally determined.

The present invention has been made in view of this point, and its purpose is to focus on the fact that when operating keys are operated continuously, the only signal that is finally determined is the signal that needs to be transmitted, and the purpose of the present invention is to By transmitting only the signals that have been detected, the battery consumption is reduced by the amount of intermediate signals that are transmitted.
The purpose is to extend the life of the battery.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, if the operation key is operated again within a set time after operation, the transmission of a signal based on the first operation is prohibited. There is.

In other words, the specific solution of the present invention is as shown in FIG.
h, and a control unit 7 that uses a pre-provided battery 10 as an internal power source and transmits signals corresponding to the operation keys 5a to 5h based on manual operations of the operation keys 5a to 5h. The target is Then, the control unit 7 is provided with an operation key 5.
operation detection means 15 for detecting operations a to 5h;
Upon receiving the output of the operation detection means 15, the operation key 5a
A timer means 16 measures a set time from the end of the operation of ~5h, and the operation detecting means 15 detects the operation keys 5a~ within the set time measured by the timer means 16.
The control means 17 prohibits the transmission of the signal when the operation of the operation keys 5h is redetected, and transmits the signal when the operation of the operation keys 5a to 5h is not detected again within a set time.

(Function) With the above configuration, in the present invention, the operation key 5a
5h are operated continuously, when the first operation of the operation keys 5a to 5h is detected by the operation detection means 15, the time elapsed after the end of the operation is measured by the timer means 16, and the time elapsed after the end of the operation is measured by the timer means 16. operation key 5a
If there is a re-operation from ~5h (signal content includes operation of other operation keys of the same type), the control means 17 prohibits the transmission of the signal based on the first operation. In that case, the operation detecting means 15 detects the re-operation of the operation keys 5a to 5h, and the timer means 16 measures the time after the re-operation is completed, so that the operation keys 5a to 5h are detected within the subsequent set time. If the above operation is repeated, the signal transmission is repeatedly prohibited by the control means 17 in the same manner as described above.

When the final operation of the operation keys 5a to 5h is completed, a signal based on the final operation is transmitted from the control means 17 when a set time has elapsed since the end of the operation.

(Effects of the Invention) As explained above, according to the signal transmitting device for a wireless remote control of the present invention, when one operation key is operated in succession, or when a plurality of operation keys with the same signal content are operated in succession, When operated with
Since only the signal based on the operation key that was finally operated is transmitted, there is no need to transmit intermediate signals, which reduces the degree of consumption of the built-in battery and extends the life of the built-in battery. I can do it.

(Example) Hereinafter, an example of the present invention will be described based on the drawings from FIG. 2 onwards.

FIG. 2 shows an embodiment applied to a wireless remote control for an air conditioner. In the figure, 1 is the main body of the air conditioner, and 2 is a wireless remote control device. Operation keys that are manually operated include a run/stop switch 4a, a display changeover switch 4b for switching between temperature display and timer display on the display section 3, and a timer reservation/cancellation switch 4.

When switching to the timer side, the timer time is changed to the UP side and
Two target temperature setting switches and timer switches 5f and 5g, which are operated to the DOWN side, and which operate the set temperature (room temperature target value) to the UP and DOWN sides when switching to the temperature control side, an air volume control switch 6a, and a wind direction control switch. Switch 6b and swing on/off switch 6
c, and an operation mode changeover switch 6d.

Therefore, the operation mode changeover switch 6d is
It consists of a momentary switch that switches the operation mode command from blower operation → automatic dry operation → automatic operation → cooling operation → heating operation → ventilation operation each time it is turned ON. In addition, the air volume adjustment switch 6a changes the air volume from H (strong) to
It consists of a momentary switch that switches from M (medium) to L (weak) to M (medium) to H (strong). Furthermore, the target temperature setting switch and timer switch 5
f and 5g each consist of a momentary switch that changes the set temperature (or timer time) by 1° C. (or 1 hour) to the UP side and DOWN side each time it is turned ON.

FIG. 3 shows the configuration of a control section provided inside the wireless remote control device 2. As shown in FIG. Control unit 7 in the same figure
The key input unit 8 connects each of the operation keys 3 to 5 to a matrix circuit to detect the operation thereof, and the microcomputer (hereinafter referred to as (abbreviated as microcomputer) 9. The control unit 7 is previously equipped with a battery 10 as an internal power source, and the voltage of the battery 10 is stepped down by a resistor R and regulated by a regulator 11 to apply a predetermined voltage Vo to the microcomputer 9. 10 as the operating power source. The microcomputer 9 converts the operation of each operation key 3 to 5 detected by the key input unit 8 into an encoded code signal corresponding to this operation (for example, a 23° C. temperature signal for the target temperature setting switch 5a). It has the function of converting. Further, an infrared output circuit 12 is connected to the output side of the microcomputer 9. The infrared output circuit 12 includes two stages of control transistors Tr1 and Tr2 that operate ON/OFF in response to a code signal output from the microcomputer 9, and two stages that emit infrared rays when the subsequent stage control transistor Tr2 is activated. It consists of infrared light emitting diodes LED1 and LED2, and this continuous emission/quenching of infrared rays is outputted to the air conditioner main body 1 as a signal for operating the air conditioner main body 1.

Next, the control of the output timing of the code signal (target temperature setting signal) by the microcomputer 9 will be explained based on the control flow shown in FIG. 4. Start,
First, in order to determine the push operation of each target temperature setting switch (operation key) 5a to 5h based on the operation of the key input unit 8, in steps S ₁ and S ₂ , when it is closed and when it is open (when ON and when OFF). is determined, and if it turns OFF after ON, target temperature setting switch 5a to 5h
The timer is determined to be operating, and a timer is started in step _S3 to measure the elapsed time T after the OFF operation.

Thereafter, in step _S4 , it is determined whether or not the target temperature setting switch operated as described above (for example, 5a) or other target temperature setting switches 5a to 5h is ON, and in step _S5 , the subsequent setting time To is determined.
Determine the elapsed time (time up) and set the set time To
If there is an ON operation before the elapse of , it is determined that the target temperature setting switches 5a to 5h have been operated continuously, the above-mentioned timer is cleared in step _S6 , and the code signal is not output and the process is continued in step _S2. Go back to that ON
The activated target temperature setting switch (e.g. 5b)
Waiting for the OFF operation and starting the measurement of the subsequent time elapsed T again in step _S3 is repeated.

On the other hand, if the target temperature setting switches 5a to 5h are not operated in steps _S4 and _S5 and the set time To has elapsed, the switch operation may be performed only once or the switch operation is finally completed. It is determined that the signal to be transmitted has been determined, and the corresponding code signal is outputted to the infrared output circuit 12 in step _S7 , and the process ends.

Therefore, according to the control flow shown in FIG. 4, steps S ₁ , S ₂ and S ₄ constitute the operation detection means 15 which detects the operation of the target temperature setting switches 5a to 5h. Step S ₃
This constitutes a timer means 16 which measures the set time To from the end of operation of the target temperature setting switches 5a to 5h. Also, step S ₅
~ _S7 prohibits the transmission of the code signal when the operation detection means 15 re-detects the operation of the target temperature setting switches 5a to 5h within the set time To measured by the timer means 16, and A control means 17 is configured to output a code signal to the infrared output circuit 12 and transmit it to the air conditioner main body 1 when the operation of the target temperature setting switches 5a to 5h is not detected again.

Therefore, in the above embodiment, if the target temperature setting switch 5a is operated only once, for example, as shown in FIG.
When the set time To has elapsed since the release time, a code signal (23°C signal) is transmitted from the microcomputer 9 to the air conditioner main body 1 via the infrared output circuit 12.

In addition, as shown in Figure B, the temperature setting switch 5
If a is operated and another temperature setting switch (for example, 5b) is operated within the set time To after it is turned off, the code signal (23°C signal) of the first temperature setting switch 5a is not sent, and the final temperature setting switch Only the code signal (24℃) that has been determined is transmitted.
The degree of consumption of the internal battery 10 can be reduced by the amount of unnecessary transmission of the intermediate 23°C signal, and the life of the battery 10 can be extended. Further, unnecessary operations in the device main body 1 can be eliminated.

Furthermore, as shown in FIG. Only the 24°C signal based on the second operation is transmitted once time To has elapsed after the end of the second operation, and unnecessary transmission of the 24°C signal based on the first operation is prohibited. It is possible to extend the service life and eliminate unnecessary operations in the main body 1 of the device.

In the above embodiment, the target temperature setting switch 5
Although the case where the timer switches a to 5h are continuously operated has been described, the same applies to the case where the timer switches 6a to 6h are continuously operated. Further, in the above embodiment, the present invention is applied to a wireless remote control for an air conditioner, but the present invention may be applied to other wireless remote controllers.
