[Technical Background of the Invention] Recently, for example, there has been a trend toward labor saving in raw material production equipment lines, and unmanned equipment is being promoted by wireless transfer 11r+] Iso. This mobile aircraft can be operated and stopped unmanned by control from a remote location on the ground. Therefore, by having the equipment perform various types of work, it is possible to safely operate equipment that operates 24 hours a day, which is highly dangerous.

An example of a conventional wireless mobile device operation control device in this building is constructed as shown in FIG. That is, as a control device on the ground side, there is an operation desk 1 that can set a mode, an automatic driving device 2 that outputs a speed command according to signals from the operation desk 1 and the ground sensor 3, and a speed command from the automatic driving device 2. It consists of a transmitter 4 that inputs and transmits radio waves, and a transmitting antenna 5 that receives the radio waves from the transmitter 4. The control device on the mobile device side includes a receiver 8 that receives radio waves from a transmitting antenna 5 via a receiving antenna 6 installed on the mobile device 7, an on-vehicle controller 9 that demodulates commands from the receiver 8, and an on-vehicle controller 9 that demodulates commands from the receiver 8. It is comprised of a drive device 10 that outputs all drive commands in response to signals from an on-board controller 9, and an on-board sensor 1.

Check the location of mobile device 7, and automatically operate device lt2.
The transmitter 4 checks the speed command, etc., transmits the command to the receiving antenna 6 of the mobile device 7 via the transmitting antenna 5, demodulates the command at the receiver 8, and sends the command to the on-board controller 9. The mobile device 7 can be moved by the drive device 10 via the drive device IO.

[Problems with background technology]

However, with such an operation control device, it is necessary to stop automatic operation when a worker enters the mobile device 7 for periodic inspection or the like. To do this, it is necessary to perform operations such as setting the mode setting switch of the operation desk 1 in the ground side control device from automatic to manual. For this reason, there is a drawback that workability is limited. Furthermore, after the mobile device 7 is stopped and boarded by setting the mode setting switch to manual, another worker may unconsciously or consciously change the mode setting and switch to automatic operation. If this automatic operation happens to be restarted when a worker is about to get off from the mobile device 7, an accident may occur. In particular, when the mobile device operates in a remote location where it cannot be seen visually, there is a high possibility that such an accident will occur.

[Object of the Invention] The present invention was made in view of the above circumstances, and regardless of the setting of the setting switch on the ground side operation desk, etc.
It is an object of the present invention to provide an operation control device for a mobile machine that improves the workability of periodic inspections of the mobile machine and allows workers who perform this work to safely get on and off the machine.

[Summary of the invention]

In order to achieve the above object, the present invention provides a means for valuing drive commands given to a drive device that drives a mobile machine so that it can be operated without entering the mobile machine,
Alternatively, a means for displaying the status of the means is further provided.

[Embodiments of the invention]

The operation control device for a mobile device according to the present invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a block diagram showing an embodiment of the device of the present invention, in which a means for turning on and off the drive command given from the receiver 8 to the drive device 10, such as a switch 12, is connected to the side of the mobile device 7. It differs from the conventional device shown in FIG. 1 in that it can be operated without getting into the vehicle, and that a display means, such as an indicator light 13, is provided to indicate the state of the switch 12, that is, the unmanned operation state, etc. be. Since the other points are the same as those in FIG. 1, the explanation thereof will be omitted here.

FIG. 3 shows a specific circuit between the transmitter 8 and the on-board controller 9 shown in FIG. 2, where 20 to 23 are drive contacts of the receiver 8, 20 is a high speed command contact, 22 is a medium speed command contact, 22 is a low speed command contact, and 23 is a brake release command contact.

Further, RYI to RY4 are relay coils provided in the on-board controller 9, and these are energized in response to a signal from the transmitter 8. Connect these as shown below. That is,
Interlocking normally open contacts J, ? of the switch 12 are connected to the side where the control bus P (for example, +24V bus?fM) and N (for example, Ov bus) quantity control power sources are connected. a,l! :'! <Connect the series circuit of indicator 13. Furthermore, control buses P and N
In between, the following 1-section circuits are connected in parallel through the switch 12 in series. High speed command contact 2 as its series circuit
0 - consists of high speed relay coil RY1, brake release command contact 23 - brake release relay coil R
It consists of Y4.

In the system configured as described above, when the mobile device 7 is to be stopped, it is done by manually turning off the mode switch on the operation desk 1 on the ground to stop unmanned automatic operation. The worker then goes to the mobile device 7 and operates the switch 12 to open it.

When the switch 12 is fully opened, the control bus lines P and N are opened, and all drive contacts 20 to 23 of the receiver 8 are cut. Therefore, even if the mode of the operation desk 1 on the ground side is set to automatic, the commands (speed command and brake release command) from the receiver 8 will not be given to the onboard controller 9, so the mobile device 7 will It stops running and remains in a braked state.

After fully opening the switch 12, the worker gets into the mobile device 7 and begins work (periodic inspection, etc.). In this state, the switch 12 is open and closed, so the continuous contact 12a is closed, and the voltage from the control power source is applied to the indicator lamp 13, so the indicator lamp 13 lights up.

After completing the work, get off the mobile device 7 and switch 12.
When the receiver 8 is closed, voltage from the control power source can be applied to the drive contacts 20 to 23 of the receiver 8, and unmanned operation can be restarted by setting the mode switch on the ground side operation desk 1. In this state, the switch 12 is closed and the interlocking contact 12h is open, so the indicator light 13 is turned off. In this manner, the state in which work such as inspection of the mobile device 1 is being performed and the unmanned operation state can be determined by turning on and off the indicator light 13.

In the embodiment described above, the switch 12 is provided on the side of the mobile device 7 and can be operated without getting on the mobile device 7.
By opening this switch 12, even if the mode switch of the operation desk 1 in a remote location is set to automatic operation, the mobile device 7 can be kept in a stopped state, and the mobile device 7 can be kept in a stopped state.
The safety of workers conducting inspections, etc. is ensured. Further, when inspecting the mobile device 7, there is no need to go to the remote operation desk 1 and turn the mode switch, so work efficiency is improved.

Furthermore, in the above embodiment, the case where there is one mobile device 7 has been described, but if there are multiple mobile devices 1, it is possible to stop only the mobile device 7 that is the target of work. This can increase the operating rate.

In addition, since the mobile device 7 is equipped with an indicator light 13 that turns on and off depending on the open/closed state of the switch 12, it is possible to tell when the mobile device is being worked on or when it is unattended. Safety for workers attempting to carry out 70-year work is essential.

Although the present invention has been described with respect to a wireless mobile device in the above-described embodiments, the present invention is not limited to this and may be any mobile device that can be moved by remote control. Further, although the mobile device can be operated unmanned by a control device on the ground, it can be operated in the same manner even if it is controlled by another mobile device. Furthermore, in the above-mentioned embodiment, the mobile device was stopped by switching the automatic mode set at the operation desk on the ground side, but when the mobile device is traveling at a very low speed, it is possible to stop the mobile device directly by pressing the switch 12. It can also be operated to stop the mobile device. Furthermore, it goes without saying that the switch 12 can be configured to be a lever-type switch that can be easily operated from the outside. It goes without saying that the display means may be any known means other than indicator lights. [Effects of the Invention] As described above, according to the present invention, it is possible to operate from the ground and turn on and off the drive command of the mobile aircraft when the mobile aircraft is bent over. All means,
Alternatively, by providing a display means for displaying the status of the means, the mobile device can be reliably stopped regardless of the operation of a setting switch on a remote operation desk.
