[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 one embodiment of the device of the present invention, in which 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 provided on the side of the mobile device 7 so that it can be operated without getting on the mobile device 7, and a display means such as an indicator light 13 is provided to display the state of the switch 12, that is, the unmanned operation state, etc. This is different from the conventional device shown in FIG. Since everything other than this point is the same as 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, is a medium speed command contact, 22 is a low speed command contact,
23 is a brake release command contact. Also,
RY1 to RY4 are relay coils provided in the on-board controller 9, and are energized by receiving a signal from the transmitter 8. Connect these as shown below. In other words, the control bus P (e.g. +24V bus)
The interlocking normally open contact 12a of the switch 12 is connected to the side to which the control power supply is connected between
and the series circuit of the display 13 are connected. Further, the following series circuits are connected in parallel between the control buses P and N via the switch 12 in series. As the series circuit, high speed command contact 20 - high speed relay coil
Consisting of RY1, brake release command contact 2
3-It consists of a relay coil RY4 for loosening the brake.

In the system configured as described above, when the mobile device 7 is to be stopped, it is done by manually switching the mode switch on the operation desk 1 on the ground to stop unmanned automatic operation. And the worker is mobile machine 7
, and open switch 12. switch 1
2 opens the connection between the control bus lines P and N, and all drive contacts 20 to 23 of the receiver 8 are cut off. Therefore, even if the mode of the operation desk 1 on the ground side is set to automatic, the commands from the receiver 8 (speed command and brake release command) are not given to the onboard controller 9, so the mobile device 7 The vehicle stops moving and the brakes remain applied.

On the other hand, after opening the switch 12, the worker gets into the mobile device 7 and performs work (periodic inspection, etc.). In this state, since the switch 12 is open, the interlocking contact 12a is closed, and the voltage from the control power source is applied to the indicator lamp 13, so the indicator lamp 1
3 lights up.

After the work is completed, when you get off the mobile device 7 and close the switch 12, voltage from the control power source can be applied to the drive contacts 20 to 23 of the receiver 8, and the mode switch on the operation desk 1 on the ground side can be applied. By setting this, unmanned operation can be resumed. In this state, the switch 12 is closed and the interlocking contact 12a is open, so the indicator light 13 is turned off. In this way, the indicator light 13 is lit,
