Automatic interlocking control method and device

The invention provides an automatic interlocking control method and device. The automatic interlocking control method comprises the steps of obtaining a vehicle speed; comparing the vehicle speed with a preset speed; when the vehicle speed is larger than the preset speed, enabling a vehicle upper part to stop working; when the vehicle speed is less than the preset speed, enabling the vehicle upper part to work; obtaining position information and voltage of the vehicle upper part; judging whether the position information is an initial position or not and whether the voltage is zero or not; when the position information is in the initial position and the voltage is zero, enabling a vehicle to run normally; and when the position information is not in the initial position and the voltage is not zero, enabling the vehicle speed to be less than or equal to the preset speed. The automatic interlocking control device is used for executing the automatic interlocking control method. The automatic interlocking control method has the advantages that automatic interlocking between vehicle running and the upper part is realized, the safety accidents caused by non-standard operation are prevented, the control method is very easy to realize and the operation is simple.
