JPH03168808A - Remote control device for moving agricultural machine - Google Patents

Abstract

PURPOSE:To easily judge whether an operating position is exactly driven or not by providing a remote control side terminal equipment with a display device for receiving and displaying the working information of a working vehicle. CONSTITUTION:The remote control side terminal equipment 1 is constituted of arranging operation keys 3 and a digital display device 4 on an operation keyboard 2 and arranging a transmitter 5 for transmitting the contents of operation and a receiver 6 for receiving information from the working vehicle side in its inside. When the terminal equipment 1 is operated and a signal is received by a working vehicle side receiver 11 through radio communication, objective work is executed based upon an output from a controller 10. The working information is transmitted to the terminal equipment 1 by a transmitter 12 through radio waves and displayed on the display device 4 and a worker operates the machine while observing the display information on the device 4. Thus, exact working operation can be attained.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a remote control device for mobile agricultural machinery, etc., which is used to remotely control operations such as cultivating fields, greenhouse hotbeds, etc. Can be used for agricultural work.

(Prior art and problem to be solved by the invention) When working in a greenhouse is performed by remote control, a monitor camera that monitors the work of the work vehicle is installed in the greenhouse, and the information captured by this monitor camera is used for remote control. The information is displayed on a display device at hand, and the worker remotely operates the device while looking at this display device. In this type of operation, detailed operation results of the work vehicle are not displayed, so it may be difficult to judge whether or not the operating parts are working correctly.

(Means for Solving the Problems) The present invention provides a mobile agricultural machine in which a terminal device on the operating side that remotely controls a working vehicle by wireless communication is provided with a display device that receives and displays work information of the working vehicle. It is configured as a remote control device.

(Function) When a terminal device is operated and wireless communication is received by a receiver on the work vehicle side, the desired work is performed by the output from the controller. This work information is wirelessly transmitted by the transmitter to the terminal device and displayed on the display device. The operator performs operations while viewing the displayed information on this display device.

(Effects of the Invention) In this way, in remote control, the work vehicle side displays information on whether or not the working part, which was executed based on the reception from the terminal device, moved as intended on the display on the terminal device side. Since the information is transmitted to and displayed on the screen, remote control can be performed while checking this display, and accurate work operations can be performed.

(Example) In the illustrated example, a terminal device 1 has an operation key 3 arranged on an operation keyboard 2, a digital display device 4, a transmitter 5 for transmitting operation contents inside the device, and a work vehicle side A controller 7 having a microcomputer CPU for processing this information has a memory 8 for storing information. 9 is a transmitting and receiving antenna.

The work vehicle is equipped with a controller 10 having a microcomputer CPU, a receiver 11 for receiving operation signals from the terminal device 1, and a transmitter 12 for transmitting work information of the work vehicle to the terminal device 1. establish. 13 is its antenna. The working unit 14 includes, for example, various types of motors for automatically steering the steering wheel, and a controller 1.
The operation is controlled by the output from 0, and an information signal indicating whether or not this working part 14 has been operated is entered into the memory 15 from 7 to 7. When the transmission of the operation signal from the terminal device 1 side is completed, the information stored in the memory 15 is automatically transmitted to the receiver 6 of the terminal device 1.

The controller 10 on the work vehicle side sequentially outputs the operation stroke of each work part 4 to the transmitter 12, and is provided with a work sensor that detects the operation of the work part 4, and transmits the detection information by the work sensor to the transmitter 12. The structure is such that it is output to.

The display device 4 as described above displays information such as whether or not communication has been established in addition to work information in the work section 4.
Such work contents and information are stored in the memory 15 of the controller 10 on the work vehicle side, and when the work section 14 is not under output control, the work section 14 is executed as is. Further, when the working unit 14 is in execution, the execution is carried out after waiting for the completion of this execution.
