Part has been more than the requirement of production plan；
At this point, the control of intelligent terminal is according to the first process time, second process time, the remaining yield
It carries out simplifying the piece count of processing and the workpiece of normal process for, remaining time, workpiece's qualification rate calculating
Quantity；
Wherein, the first process time was 10 minutes, and second process time is 5 minutes, and the residue yield is 900
Part, the remaining time are 5 days, i.e., 7200 minutes, the workpiece's qualification rate was 95%, and the workpiece of processing is simplified described in the note
Quantity is M, remembers the piece count N of the normal process；
Wherein, M, N meet M*0.95+N*0.95=900, and 10*N+5*M=7200；The workpiece number of processing ought be simplified
Amount about 456, when the piece count of normal process is 492, production plan can be completed before completing the time limit, while to the greatest extent may be used
Reducing for energy only carries out slightly inspecting the piece count tested by random samples；
Then, from this point on, the control of intelligent terminal is only carried out slightly inspecting by random samples and be tested to preceding 456 measured workpieces, and thick sampling observation is tested
Processing is irrigated after qualification；Since the 457th measured workpiece, the control of intelligent terminal is again introduced into normal detection mould
Block carries out the first vacuumize process, pressure maintaining processing and the second vacuumize process, i.e., thick pumping, pressure maintaining, essence to subsequent measured workpiece

One vacuum performance characteristic group is also matched with corresponding pressure retaining valve in every group of vacuum performance characteristic group respectively
Value, the temporal characteristics of note N group vacuum performance characteristic group are N temporal characteristics, remember N group vacuum performance characteristic group
Pressure maintaining threshold values be N pressure maintaining threshold values；
Then, the control vacuum pump or vacuum pump group carry out pressure maintaining processing to the measured workpiece, specifically include:
When the first time is equal with N temporal characteristics value, N pressure maintaining threshold values is obtained；
Vacuum pump or vacuum pump group stopping are controlled to the vacuumize process of the measured workpiece, and after the default pressure maintaining duration of waiting,
The vacuum degree for obtaining the measured workpiece at this time, is denoted as the second vacuum degree；
When second vacuum degree is not more than the N pressure maintaining threshold values, generates pressure maintaining and handle qualifying signal.
6. workpiece vacuum detecting as claimed in claim 5 and perfusion integrated control method, which is characterized in that described every group true
It is also matched with corresponding slope value and criteria threshold respectively in empty performance characteristic data group；Remember the N group vacuum performance feature
The slope value in data group is N slope value, remembers that the slope value in the N group vacuum performance characteristic group is
N criteria threshold；
Then, the control vacuum pump or vacuum pump group carry out the second vacuumize process to the measured workpiece, specifically include:
When second vacuum degree is not more than the N pressure maintaining threshold values, N slope value and N criteria threshold are obtained；
It controls vacuum pump or vacuum pump group and vacuumize process is carried out to the measured workpiece again；
Third curve of vacuum is generated according to acquired vacuum degree, calculates the minimum slope of the third curve of vacuum,
It is denoted as the third slope of curve；
When the third slope of curve and the N slope value match and acquired vacuum degree is no more than N mark
When quasi- threshold values, the second vacuumize process qualifying signal is generated.
7. such as workpiece vacuum detecting as claimed in any one of claims 1 to 6 and perfusion integrated control method, which is characterized in that institute
It states control vacuum pump or vacuum pump group and vacuumize process is carried out to measured workpiece, before further include:
Judge whether measured workpiece reaches station；
When measured workpiece reaches station, start to detect.
