る。In addition, in the present invention, the proximity sensors 8a-8c are provided.
The timer 13 provides a time lag of, for example, about 2 seconds between the time when the wheel 5 is lifted up and the time when the emergency braking device 12 and the alarm AR are activated.
Only when the mobile vehicle 1 is traveling by the speed detection device 14, all the proximity sensors 8a to 8c or the emergency braking device 12 are provided.
Also, the alarm AR is turned on, and when the vehicle is stopped, all of these are turned off, so that the emergency braking device 12 and the alarm AR in the defective track portion are controlled sensitively, and the defective track is also generated. It is possible to safely perform maintenance work by controlling useless operations of the emergency braking device 12 and the alarm AR when the vehicle is stopped at a part and working.
