Fool-proof control method and device

The invention relates to the field of fool-proof control, in particular to a fool-proof control method and device. The method comprises the following steps: detecting working states of a plurality of control buttons; when it is detected that the working state of the control button is an open state, identification state information is generated; a reset instruction containing the identification code is generated according to the identification state information, and the reset instruction is sent to the pressing assembly, so that the pressing assembly enters a reset state; when it is detected that the pressing assembly is in the reset state, a reset completion signal is generated; controlling the air clamping structure to be in an open state according to the reset completion signal; and after the preset delay time, the jacking structure is controlled to run to the workpiece lower plate position, so that the workpiece on the workpiece machining table is in a removable state. The time sequence action among the pr
