The difference of electric current and host real-time current) lasting number is when picking up the second less than or equal to 5A, programmable controller 2 will issue interrupt it is more
The program control command of section speed operation, and automatically switch back into normal sawing state；
It, can 5, if the PLC multistage speed operation program operation of programmable controller 2 does not occur above situation also in 2 hours
Programming sequence controller 2 will be deemed as putting the first edge on a knife or a pair of scissors unsuccessfully, and board by automatic shutdown protection and issues and " can not put the first edge on a knife or a pair of scissors, please separately replace at this time
The prompt information of rope saw ".
In addition, also introducing dead zone protection program in programmable controller 2 (i.e. in the range of the certain minor change of electric current
Inside any adjustment is not made to the speed of travel, programmable controller 2 makees " PI " just for the current change quantity outside " dead zone " range
Process control processing), so that the normal service life of bead string rope be effectively ensured, not the slight change of reason load current and excessively
The frequent adjustment speed of travel leads to the unnecessary frequent contraction of bead string rope, tensile damage in turn, and influence bead string rope uses the longevity
Life.
In addition, also introducing the end of board sawing finishing phase in programmable controller 2 --- judge automatically identification,
Adjustment, amendment, compensation program realize that segmentation reduces host running speed (the line of cut gradually in proportion step by step in finishing phase
Speed), thus realize the whole smoothly auto-control of system and need not any human intervention just can under automatic control mode from
Easier, intelligence dynamic to complete, and whole can show optimal sawing state, while the operation of board can also be made to become, specifically
Steps are as follows:
1, it analyzes and determines first
It is continued to decline when host real-time current occurs in sawing process in diamond bead rope saw machine, it is inclined with its setting value
Residual quantity increases gradually and when gesture without recurrence, and programmable controller 2 will determine that board has entered workshop section of finishing up；
2, when programmable controller 2 determines that board has entered ending workshop section, programmable controller 2 will reduce automatically
When the real-time current and setting electric current of the operating frequency of host to host are close, keep the operating frequency to the arrival of subsequent cycle
When repeat above-mentioned working condition to operation and terminate.
Another way then programs board ending operating instruction according to mining big data:
1, it analyzes and determines
It is continued to decline when host real-time current occurs in sawing process in diamond bead rope saw machine, it is inclined with its setting value
Residual quantity increases gradually and when gesture without recurrence, and programmable controller 2 will determine that board has entered workshop section of finishing up；
2, when programmable controller 2 determine board has entered finish up workshop section when, programmable controller 2 will be automatically into
PLC multistage speed runs running state of programs, and control host operating frequency reduces simultaneously continuous operation step by step and for a period of time, then drops to
Next stage operating frequency and the duration of runs, the setting in relation to each section of running frequency of host and runing time depend on adopting for big data
Collect situation, the intelligence degree of the higher board of big data precision is also higher.
