PURPOSE:To improve operating efficiency by figuring out the scheduled work volume from the details of operation and by judging whether or not a truck can be operated in comparison with the allowance work volume of a storage battery of the truck. CONSTITUTION:When details of operation are set up, a scheduled work volume is figured out from them and transmitted to a designated truck. As soon as the scheduled work volume is received from a control unit on the ground side, the allowance work volume is figured out on the truck side from the difference between the voltage of a storage battery and the set-up voltage. Then, in comparison with the scheduled work volume and an allowance work volume a judgement is made whether or not it is possible to accept the command of operation of the scheduled work volume. If the operation is all right, then a grant signal is sent out. Afterwards, the operation starts when a command for details of operation is received from the control unit on the ground side. On the contrary, if the judgement is 'no' for operation, then a reject signal is transmitted. |
