In the effective signal area, controls the tablet press machine and the current first tablet is divided into invalid tablet queue；
The second numeral output submodule does not exist if being additionally operable to described current second and rushing the corresponding punch pressure signal of position signal
In the effective signal area, controls the tablet press machine and current second tablet is divided into the invalid tablet queue.
9. device according to claim 8, it is characterised in that：
First digital output module, specifically for judging that described current first rushes the corresponding punch pressure signal of position signal and be
It is no to be more than the first preset pressure threshold value and be less than the second preset pressure threshold value；If described current first rushes the corresponding punch of position signal
Pressure signal is more than the first preset pressure threshold value and is less than the second preset pressure threshold value, judgement current first punching
Signal corresponding punch pressure signal in position is in the effective signal area；The first preset pressure threshold value and described second is in advance
If pressure threshold is the boundary value of the effective signal area；
Second digital output module, specifically for judging that described current second rushes the corresponding punch pressure signal of position signal and be
It is no to be more than the first preset pressure threshold value and be less than the second preset pressure threshold value；If described current second rushes position signal pair
The punch pressure signal answered is more than the first preset pressure threshold value and is less than the second preset pressure threshold value, works as described in judgement
Preceding second rushes the corresponding punch pressure signal of position signal in the effective signal area.
10. device according to claim 9, it is characterised in that：
First digital output module is additionally operable to judge whether described current first rush the corresponding punch pressure signal of position signal
Less than the first preset pressure threshold value or it is more than or equal to the second preset pressure threshold value；If described current first rushes position signal pair
The punch pressure signal answered is less than the first preset pressure threshold value or is more than or equal to the second preset pressure threshold value, judgement
Described current first rushes the corresponding punch pressure signal of position signal not in the effective signal area；
Second digital output module is additionally operable to judge whether described current second rush the corresponding punch pressure signal of position signal
Less than the first preset pressure threshold value or it is more than or equal to the second preset pressure threshold value；If described current second rushes position signal pair
The punch pressure signal answered is less than the first preset pressure threshold value or is more than or equal to the second preset pressure threshold value, judgement
Described current second rushes the corresponding punch pressure signal of position signal not in the effective signal area.
