Description

[Detailed description of the invention] [Industrial application field] The present invention has a trim setting section consisting of a button switch, and can remotely control models, industrial equipment, etc. by transmitting control signals according to station operations. This relates to radio-controlled transmitters.

[Prior Art] Generally, remote control of a controlled object such as a model or industrial equipment is performed based on the operation of a stake provided on a transmitter body. That is,
When the stake is operated as shown in Figure 3,
A signal is selectively taken in by a multiplexer 2 via a variable resistor 1 linked to this stake, and this taken signal is converted into a digital signal by an A/D converter 3, and then sent to a calculation part 4, a parallel After predetermined signal processing is performed via the serial conversion section 5 and the high frequency circuit section 6, radio waves are transmitted from the antenna 7. At this time, the calculation section 4 performs calculation processing on the output signals of the setting section 10 for setting the exponential and the like, the counter 11 representing the neutral position of the stake, and the output signal of the A/D conversion section 3. Then, the transmitted radio waves are received by a receiver provided in the controlled object, thereby allowing the controlled object to be controlled in a desired manner. At this time, the neutral position of the stake is set by pressing a button switch 9 in the trim setting section 8. When performing the above-mentioned control, the setting position differs depending on the number of times the button switch 9 is pressed.
The output of the counter 11 that counts the number of times the button is pressed is output to the calculation unit 4 only for the purpose of performing the above-mentioned control.
The number of times the button was pressed was memorized.

[Problems to be solved by the invention] However, with the above-mentioned conventional radio-controlled transmitter, the operator must memorize the number of times the button switch 9 has been pressed, which makes the task complicated and requires concentration on the operation. I had a problem that I couldn't do it.

In addition, if you are distracted by the maneuver and forget the number of presses, the trim setting position becomes unknown and the object to be controlled may crash if it is an airplane or drive out of control if it is a car. There was a problem that the control body could not be controlled as desired.

The present invention was developed in view of the above-mentioned problems, and its purpose is to make it possible to easily visually recognize the trim setting position without memorizing the number of times the button switch is pressed as in the past. The object of the present invention is to provide an inexpensive radio-controlled transmitter that can perform multi-stage display with a small number of display units.

[Means for Solving the Problems] In order to achieve the above object, the radio-controlled transmitter according to the present invention has a trim setting section consisting of a button switch, and controls the controlled object by sending out a control signal according to the stay operation. A radio-controlled transmitter for remotely controlling a remote controller includes a counter that counts the number of times the button switch is pressed, a decoder that converts the counted value of the counter into a corresponding parallel signal and outputs it, and a parallel signal that corresponds to each output terminal of the decoder. a display unit having display units provided, and displaying an intermediate value corresponding to each of the display units;
The feature is that this is performed by displaying a plurality of the display units.

[Operation] When the button switch provided corresponding to the stake is pressed, a counter counts the number of times the button switch is pressed. This count value is converted into a corresponding parallel signal by a decoder,
Based on this parallel signal, a display unit provided corresponding to each output terminal of the decoder is displayed.

Furthermore, the intermediate value corresponding to each display unit is displayed by displaying a plurality of display units.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of a radio-controlled transmitter according to the present invention.

Here, a two-channel transmitter will be taken as an example, and the same components as those of a conventional radio-controlled transmitter will be described with the same numbers.

The radio-controlled transmitter according to this embodiment includes a variable resistor 1, a multiplexer 2, an A/D converter 3, an arithmetic unit 4, a parallel-to-serial converter 5, a high frequency circuit unit 6, a setting unit 10, a trim setting unit 8, and a counter 11. , a decoder 12, a display drive circuit section 13, and a display section 14. It remotely controls a controlled object by sending control signals in response to the operation of a stake (not shown), and a button switch. The display unit 14a of the display unit 14 shows the number of presses of 9 as shown in FIG.
~14i, in which case each display unit 1
The intermediate value of the number of presses by the button switch 9 corresponding to 4a to 14i is the display unit 14a to 14.
This is done by displaying a plurality of i's.

The variable resistor 1 is provided with a number of channels in conjunction with a stake (operation lever), and outputs a signal to the multiplexer 2 based on the operation of the stake.

The multiplexer 2 selectively takes in the signal supplied from the variable resistor 1, converts the result into a serial signal, and outputs the result to the A/D converter 3.

The A/D converter 3 converts the signal (analog signal) supplied from the multiplexer 2 into a digital signal and outputs it to the arithmetic unit 4 as a parallel signal.

The calculation unit 4 receives parallel signals from the A/D conversion unit 3,
Predetermined signal processing is performed on signals supplied from a counter 11 and a setting section 10, which will be described later, and the results are outputted as parallel signals to the parallel-to-serial conversion section 5 at the subsequent stage.

The parallel-to-serial converter 5 converts the parallel signal supplied from the arithmetic unit 4 into a serial signal and outputs the serial signal to the high frequency circuit unit 6.

The high frequency circuit section 6 transmits radio waves of a predetermined frequency from the antenna 7 to a receiver (not shown) of the steered object based on the serial signal from the parallel/serial converter 5 . As a result, when the controlled object receives radio waves, the controlled object is controlled based on the received signal.

The setting section 10 sets the mixing, exponential characteristics, etc. of each channel corresponding to the stake by, for example, external key operations.

The trim setting section 8 is equipped with a pair of push switches 9 corresponding to the stakes provided for each channel, and outputs a signal to the counter 11 when pushed and operated by the operator from the outside. The neutral position of the stick can be set according to the number of times the button switch 9 is pressed.

The counter 11 counts the number of times the button switch 9 is pressed, and is provided for each button switch group.The counter 11 counts the number of times the button switch 9 is pressed, and counts so as to increase the signal from one button 9a of the pair of button switches 9, and the counter 11 counts the number of times the button switch 9 is pressed. The calculation unit 4 and the decoder 1 count the signals so as to reduce the signals from the
It is output to 2.

Note that the display units 14f to 14i arranged on the right side of the central display unit 14e are arranged in such a manner that the number of times the button switch 9a is pressed in one direction of operation of the stick is 2, 4, 6, and 8, respectively.
Furthermore, the display units 14a to 14d arranged on the left side correspond to the number of presses of the button switch 9b in the other direction of operation of the stake: 2 times, 4 times, 6 times, and 8 times, respectively. ing.

Next, the operation of the above-described configuration will be explained.

When the button switch 9 of the trim setting section 8 is pressed to remotely control the controlled object based on the stick operation, the counter 11 sequentially receives the signal supplied from the button switch 9 and presses the button. Count the number of times. These counted values are converted by the decoder 12 into parallel signals corresponding to each numerical value. This parallel signal lights up a display unit at a predetermined position via the display drive circuit section 13, and the number of times the push switch 9 is pressed is displayed.

In addition, the display of the intermediate value corresponding to each display unit 14a to 14i, that is, the display of the number of presses by the button switch 9 in the middle of each display unit that cannot be displayed by the display unit alone, is performed by displaying the adjacent display unit. It is done by folding.

By the way, in the above-mentioned embodiment, a case where an intermediate value is displayed using a plurality of display units 14a to 14i and display is performed an odd number of times using two adjacent display units will be explained as an example. However, the same configuration can be used even if an even number of times is used, and a plurality of display units may be combined and displayed.

Furthermore, in the above-described embodiment, the explanation was given using an LED as an example of the display unit 14 that displays the number of times the button switch 9 is pressed, but a liquid crystal display device or the like may be used.
