Description

Description: TECHNICAL FIELD The present invention relates to a radio control transmitter used for remotely controlling a steered device such as an airplane, a helicopter, and a vehicle, and more particularly, to a steered device. The correlation between the operation amount of the stick lever and the control data can be set and input without transmitting the control data.

(B) Background of the Invention In a radio control transmitter, a servo of a steered device is operated by operating a stick lever to cause a steered device to perform a predetermined operation. At this time, the operation amount of the stick lever is detected by operation amount detection means such as a volume, and control data corresponding to the detection result is transmitted to the servo of the steered device. The servo operation amount has a predetermined correlation with the lever operation amount as shown in FIG. 7, and this correlation changes depending on the type of the controlled device, individual differences thereof, the operation operation content, and the preference of the operator. It should be. This change is a change in the slope of the dual-rate diagram 71 shown in FIG. 7 and a change in the curvature of the exponential curve 72. For this reason, it is proposed that the operator can set the correlation between the operation amount of the stick lever and the servo operation amount for each of the volumes for detecting the operation amount of the stick lever, and store the setting contents. Has been issued.

(C) Problems to be Solved by the Invention However, if the correlation between the operation amount of the stick lever and the control data is set and input in a state where the transmission unit forming a part of the radio control transmitter is enabled, the transmission unit There is a problem that the data at the time of setting input is transmitted, interferes with a steered device remotely controlled by another radio control transmitter in the vicinity, and prevents another operator from performing a normal steering operation.

An object of the present invention is to make it possible to invalidate the operation of the transmission unit when setting and inputting the correlation between the operation amount of the stick lever and the control data, and to prevent transmission of control data from the transmission unit when setting and inputting the correlation. Another object of the present invention is to provide a radio control transmitter that does not interfere with a steered device that is operated by another operator in the vicinity.

(D) Means for Solving the Problems A radio control transmitter according to the present invention is a radio control transmitter for transmitting control data having contents correlated to the operation amount of a stick lever to a steered device. Correlation setting means for setting and inputting the correlation between the amount and the control data, and transmission stopping means for stopping transmission of control data to the steered device when the correlation setting is input by the correlation setting means. Features.

(E) Operation In the present invention, when the transmission stop means is enabled,
When setting and inputting the correlation between the operation amount of the stick lever and the control data, transmission of the control data to the steered device is stopped. Therefore, control data before and after the setting input operation is not transmitted from the transmission unit, and does not interfere with a steered device remotely controlled by another radio control transmitter in the vicinity.

(F) Embodiment FIG. 1 is an external view of a radio control transmitter according to an embodiment of the present invention.

Stick levers 22 and 23 are provided in front of the radio control transmitter 21. This stick lever 22,
Each of 23 can be moved up and down and left and right, and the operation amount is respectively detected by volumes V1 to V4 (not shown). Further, switches S1, S2 and volumes V7, V8 are provided above the stick levers 22, 23. Further, on both sides of the radio control transmitter 21, volumes V5 and V6 are provided, and switches S3 and S4 are provided on the upper surface together with buttons B1 and B2.

FIG. 2 is a block diagram of the radio control transmitter.

The operation amounts of the stick levers 22 and 23 in the vertical and horizontal directions are electrically detected by the built-in volumes V1 to V4. A constant voltage is applied to both ends of the volumes V1 to V4, and a voltage value corresponding to the operation amount of the stick levers 22, 23 is detected from the intermediate tap. The voltage value detected when the stick levers 22 and 23 are in the neutral position is 2.5 V, and the voltage is 2-3 V by operating the stick levers.
Vary between. The A / D conversion circuit 11 digitally converts a value obtained by subtracting 2.5 V from the voltage values input from the volumes V1 to V4 (that is, how much the voltage rises or falls around 2.5V) as operation amount data. The manipulated variable data converted by the A / D conversion circuit 11 is input to the adder 12 via the switch 19. The adder 12 calculates the control data by adding the operation amount data to the reference value. The control data is converted again into an analog value by the D / A conversion circuit 13, is PCM-modulated by the PCM transmitter 14, and is transmitted to the steered device.

The reference value register 18 is connected to the adder 12. A reference value is set in the reference value register 18 in advance. The buffer register 16 is connected to the reference value register 18 via a gate 17. The buffer register 16 receives data from the controller 15 and outputs data to the gate 17 and the switch 19. The controller 15 is constituted by a microcomputer.

FIG. 3 is a block diagram of a controller of the radio control transmitter.

The controller 15 is configured by connecting a ROM 32 and a RAM 33 to a CPU 31. The contents of the function storage means 81 shown in FIG. 8 are stored in the ROM 32. These contents are functions to be defined for the volumes V1 to V8, switches S1 to S4, and buttons B1 and B2 provided in the radio control transmitter 21. Each volume V1 is stored in the memory area M1 of the RAM 33.
