judging whether the discharging car reaches a target preset position or not according to the current position information;
if the discharging car reaches the target preset position, the superior control system sends a stop command;
and the unloading car receives the stop command and stops running.
6. The method of claim 1, wherein the superior control system receives the operation speed information, and further comprises, after calculating current position information according to the operation speed information and a time interval corresponding to the time interval between the reception of the position signal and the operation speed information:
judging whether the discharging car reaches a target preset position or not according to the current position information;
and if the discharging car reaches the target preset position, automatically stopping.
7. The utility model provides a dummy car hard-line control device which characterized in that includes:
the first sending module is used for transmitting the position signal of the un-started running of the unloading vehicle to the superior control system through a hard wire;
the first receiving module is used for receiving the position signal by the superior control system, generating a starting signal and sending the starting signal to the discharging car through a hard wire;
the second sending module is used for the unloading car to receive the starting signal to start running and sending running speed information in the running process to the superior control system through the hard wire;
and the second receiving module is used for receiving the running speed information by the superior control system and calculating the current position information according to the running speed information and the time interval corresponding to the received position signal and the running speed information.
8. The apparatus of claim 7, wherein the first receiving module comprises:
the generating submodule is used for generating a manual state starting signal or an automatic state starting signal according to the position information of the discharging car;
and the sending submodule is used for sending the manual state starting signal or the automatic state starting signal to the discharging car through a hard wire.
9. A computer device, comprising:
a memory and a processor, the memory and the processor being communicatively connected to each other, the memory having stored therein computer instructions, the processor executing the computer instructions to perform the method of hard-line control of a dump truck according to any of claims 1-6.
10. A computer-readable storage medium storing computer instructions for causing a computer to perform the method of any one of claims 1-6.
