Abstract

PROBLEM TO BE SOLVED: To provide a technology which enables work to be safely and efficiently performed by facilitating an operation of a remote-controlled working machine.SOLUTION: This remote-controlled indoor operation unit 1 is formed by arranging a sitting seat 11 and operation means 12, 13 and 14, which are similar to types for being arranged in the operator cab of the working machine, in a remote-controlled operation room 4. In the remote-controlled indoor operation unit 1, since the remote-controlled operation room 4 is formed in such a manner that any one of the sitting seat 11 and the operation means 12, 13 and 14 is arranged just as in the case of the inside of the operator cab of the remote-controlled working machine, an operator can perform the operation without feeling any sense of discomfort, while having a feeling of actually sitting on the sitting seat of the operator cab of the working machine.

Description

  The present invention relates to a remote control indoor operation unit.

  Conventionally, many work machines such as hydraulic excavators are used in places where there is a high risk of falling accidents such as earth and sand, stones, etc., so at work sites where safety is expected, the work machines are wirelessly controlled by remote control. It is often done with.

  Normally, in remote control of a work machine, by operating an operation unit equipped with a lever or switch, an operation signal is wirelessly transmitted to the work machine based on the operation, and the operation signal is received on the work machine side. To perform the desired operation.

  In addition to a fixed arrangement in the operation chamber, the operation unit may be a portable mobile type that can be carried.

  By the way, unlike a general vehicle, the operation of the work machine needs to move various body parts such as an arm part and an upper revolving body in addition to moving the vehicle body from front to back and from side to side. For this reason, even in the operation unit, switches, levers and the like corresponding to all the operation means arranged in the actual driver's seat are mounted, so it is difficult to understand which switches and levers correspond to those in the actual driver's seat. The operability was not very good. For this reason, workability was not good, and work productivity was not good.

  The present invention has been devised in view of the above-described problems of the prior art, and is intended to provide a technique for facilitating the operation of a remotely controlled work machine and enabling safe and efficient work.

  For this reason, the remote control indoor operation unit according to the present invention is formed by disposing a seat seat and operation means similar to those disposed in the operator's cab of the work machine in the remote control operation chamber. It is characterized by.

  Here, the operation means refers to a set of all operation means (operation panel, operation lever, operation switch, operation pedal, etc.) provided around a seat seat arranged in a cab of a work machine that is remotely controlled. .

  According to the remote control indoor operation unit according to the present invention, the remote control operation room is formed in the same arrangement configuration as the operation room of the work machine to be remotely controlled for any of the seat seat and the operation means. Therefore, the operator can operate without any sense of incongruity as if he / she was actually sitting on the seat in the cab of the work machine. For this reason, it is possible to perform the remote control operation very easily as compared with the conventional case, and the working efficiency is remarkably improved.

It is an apparatus block diagram of the specific embodiment example which concerns on this invention.

  An example of a specific form according to the present invention will be described with reference to FIG. This embodiment is an example applied to a hydraulic excavator. In addition, the form example shown below is an example of this invention to the last, Comprising: Of course, this invention is not limited to them.

  As shown in the figure, this embodiment is premised on a system in which the excavator B is remotely controlled by the remote operation means A formed in the operation chamber 4. For this reason, the remote control means A and the hydraulic excavator B are wirelessly communicated by the transmitter 3 constituting the remote control means A and the receiver 5 installed in the hydraulic excavator B.

  The remote control means A and the hydraulic excavator B are basically the same as the conventional remote control system configuration. That is, the remote operation means A, the indoor operation unit 1 for operating the operation of the work machine, the controller 2 that receives the operation signal from the operation unit 1, and outputs a command based on the operation signal to the transmitter 3, The transmitter 3 is configured to transmit an operation signal in accordance with a command from the controller 2. On the other hand, the hydraulic excavator B includes a receiver 5 that receives an operation signal from the transmitter 3, an operation controller 6 that controls an operation unit based on the operation signal received by the receiver 5, and an operating device 7 that operates the operation unit. It consists of.

  In such a remote control system, the feature of this embodiment is the indoor operation unit 1. The indoor operation unit 1 is formed by disposing seat seats and operation means exactly the same as those disposed in the cab of the hydraulic excavator B. That is, the seat seat 11, the control lever 12, the console 13 equipped with the switch, and the operation pedal 14 arranged in the cab of the excavator B are provided in the operation room 4 with the arrangement. The devices forming these indoor operation units 1 are the same as the normal operation units arranged in the cab of the hydraulic excavator B, and are used to move the operation parts of the hydraulic excavator B such as blades, rear excavator, and traveling crawler. Output a signal.

  In this embodiment, when the lever 12 of the indoor operation unit 1 of the remote operation means A, the switch of the console 13 and the operation pedal 14 are moved, the operation signal is output to the controller 2. The controller 2 transmits the operation signal to the excavator B wirelessly via the transmitter 3. In the hydraulic excavator B, the operation signal is received by the receiver 5, a signal is output to the operating device 7 via the operation controller 6, and the hydraulic excavator B moves. At that time, the structure of the indoor operation unit 1 is usually exactly the same as the structure of the seat seat and the operation means provided in the cab of the hydraulic excavator B, so that each operation means of the indoor operation unit 1 If is operated, the excavator B can be moved in exactly the same manner as in the actual cab of the excavator B. Therefore, according to the present embodiment, the operator can operate without any sense of incongruity as if he / she was actually sitting on the seat seat of the operator's cab. Therefore, the remote control operation can be performed very easily, the working efficiency is remarkably improved, and the productivity is improved. Moreover, since the apparatus configuration of the conventional remote control system is used as it is except for the indoor operation unit 1, a wireless mobile operation unit (not shown) that can use the system can also be used. Therefore, for example, when it is necessary to operate in the vicinity of the vehicle, such a wireless mobile unit can be actively used in place of the indoor operation unit 1, which is extremely useful.

  Needless to say, the present invention is not limited to the above-described embodiments. For example, another vehicle such as a bulldozer may be used as a working machine to be applied. In addition, various modifications such as a structure in which the controller 2 is built in and integrated with the indoor operation unit 1 or a structure in which the operation controller 6 is integrated in the actuator 7 may be made. As long as the configuration of the claims is satisfied, even if the above configuration is changed as appropriate, it naturally belongs to the technical scope.

  The present invention can be applied as a structure for forming an operation chamber for remotely controlling a work machine such as a hydraulic excavator or a bulldozer.
