Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winch operating method and an apparatus for pulling and suspending an unspecified object using an onboard apparatus, and more particularly to a wireless operation and an apparatus for operating the apparatus wirelessly. Related to

[0002]

2. Description of the Related Art Generally, a remote control device can be operated with one or two switches when a certain device is operated or when the operation is simply started and stopped. However, when a delicate operation is required, a joystick lever that is easy for the operator to operate sensuously has been used relatively frequently. In general, the joystick lever can be operated quantitatively such as speed and position according to the tilt angle, and stops at the neutral position. For this reason, a sensor that detects the lever angle is attached to the base of this joystick lever, and the information signal from it, for example, an analog signal such as the level of the voltage level, is received by the wireless transmission device and transmitted as a signal of a certain radio wave. Then, the wireless receiving device that receives it converts the signal into an analog signal of a level that moves the device to be operated and transmits it.

In recent years, a digital communication system which is resistant to noise and obstacles and can transmit a large amount of information has been used. Even in this case, an analog signal is digitized and transmitted, and the receiving side converts it into an analog signal again. In principle, they are the same.

[0004]

In these conventional systems, a conversion circuit is required for converting an information signal into a radio signal for both transmission and reception, and vice versa. In particular, since the transmitting side needs to be easily handled by the person who operates it, it is required to reduce the size and weight as much as possible. However, there is a problem that it is necessary to add a conversion circuit or the like which tends to be complicated, and it is difficult to reduce the size and weight. In addition, there is also a problem that a complicated device is required such that a similar circuit must be redundantly added for both transmission and reception.

[0005] Further, even among devices of the same type, devices having different outputs and the like have different specifications such as conversion levels, so that the same wireless device cannot be used for both transmission and reception as they are, and each device becomes a dedicated device. There was also a problem with compatibility, which was not easily available.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless operation device which is small and lightweight, can be operated easily, and can perform complicated control.

Even winch devices with different specifications can be handled by first making simple settings changes. As described above, it is possible to provide a wireless operation device that is small, lightweight, and capable of performing complicated control with a simple operation.

[0012]

FIG. 1, FIG. 2 and FIG. 3 show an embodiment of the operation of the present invention.
This will be described with reference to a block diagram of FIG. The winch 11 mounted on the self-propelled device 15 such as a vehicle is used for pulling, pulling, and, in some cases, suspending and raising an unspecified object 14 and lowering it. The movement of the winch 11 is mainly the feeding, winding and stopping of the rope 12. Furthermore, considering ease of use and safety, it is necessary to be able to change the operation speed

The wireless operation device 1 is a device that is operated by a person (operator) at a position where this operation is separated from the self-propelled device 15 such as a vehicle and is easily monitored and confirmed. The switches assigned to this device are a feed-out switch 3a, a take-up switch 3b, a speed-up switch 3c, and a deceleration switch 3d. Extending switch 3a / winding switch 3b
Keeps its operation as long as it is depressed.
c. The deceleration switch 3d operates only while the feeding switch 3a or the take-up switch 3b is pressed, and the speed changes in proportion to the pressing time, and maintains the speed when the switch is released.

This will be described including the operation of each device.
For example, the rope 12 is extended to an object 14 which is a towed object (the shape of the object is various). When the operator presses the extension switch 3 a of the wireless operation device 1, the command is transmitted from the transmission antenna 5 via the transmission unit 4. This is received by the receiving unit 7 from the receiving antenna 6,
The corresponding switch 3a 'on the receiving side is turned on. As a result, the microcomputer 8 executes a process corresponding to the payout.

As shown in the block diagram of FIG. 3, the microcomputer 8 has an input interface 8a, a central processing unit (CPU) 8b, and an output interface 8
c, and the receiving unit 7 receives the signal from the transmitting unit 4, and the switches 3a 'to 3d' corresponding to the pressed switches 3a to 3d are turned on. Then, the input interface 8a converts the signal into a voltage level signal and transmits it to the central processing unit (CPU) 8b. Accordingly, the central processing unit (CPU) 8b executes a preset payout process, instantaneously calculates the applied voltage of the electric flow control valve 10 for operating the winch 11 at the lowest speed in the payout direction, and calculates the voltage. The data is output to the output interface 8c. The output interface 8c converts the voltage data into an 8-bit parallel signal and transmits the 8-bit parallel signal to the analog converter 9, whereby the electric type flow control valve 10 operates in the direction in which the winch 11 extends at the lowest speed. It starts to move in the direction in which the rope 12 is extended. At first, make a very slow movement considering safety. In order to improve workability, the operator presses the speed-up switch 3c while pressing the extension switch 3a. Then, inside the microcomputer 8, the judgment is made and the central processing unit (CPU) 8b executes the process of increasing the speed.
As a result, the voltage applied to the electric flow control valve 10 slowly increases, and the driving speed of the winch 11 increases. The operator keeps pressing the speed-up switch 3c until the appropriate speed is reached,
When the speed-up switch 3c is released, the speed is maintained.
When the rope 12 approaches the towed object 14, the speed is reduced by pressing the deceleration switch 3d, and then the winch 11 stops when the hand is released from the extension switch 3a. Similarly, in the case of winding, the winding is performed by pressing the winding switch 3b, and the speed increasing switch 3c and the speed reducing switch 3d are wound.
, The take-up speed is changed, and the hand is released from the take-up switch 3b to stop.

[0016] As described in claim 6, the "on / off"
As shown in FIG. 6, the switch 3 is replaced with a "speed-up / deceleration switch" instead of the "speed-up switch 3c and the deceleration switch 3d" in the switch described in the above item [0015]. A structure including a seesaw type "on / off" switch 16 that returns to a neutral position when released, and includes a payout switch 3a and a takeup switch 3b corresponding to the payout switch 3a and the takeup switch 3b in claim 5. Then, a wireless winch operation substantially corresponding to the operation described in the above section [0015] is performed (see FIGS. 7 and 8).

As described above, the microcomputer 8 on the receiving side controls the movement of the hydraulically driven winch 11 through the analog converter 9 in accordance with the state in which the "on / off" switch 3 of the wireless operating device 1 is pressed. The electric flow regulating valve 10 to be controlled can be moved. An example of a series of movements of the "ON / OFF" switch 3, the analog converter 9 and the winch 11 is shown in FIG.

[0018]

1 to 4 show an embodiment of the present invention. 6 to 8 show another embodiment of the present invention.
As shown in the figure, the speed increasing switch 3c and the speed reducing switch 3d are replaced by a seesaw type "on / off" switch 16 which returns to a neutral position when the hand is released.

[0019]

According to the present invention, the wireless operating device is a simple
It is only necessary to provide several "OFF" switches and to transmit which switch has been pressed. This has the effect that the device can be made very simple, small, lightweight and easy to operate. In addition, by centralizing all control on the receiving side and performing it using a microcomputer, there is an effect that control flexibility is enhanced, and there is no major change in winch equipment with other specifications and conditions different. There is also an effect that it can respond.
