6. valve closes delay, for highest permission, prevent valve from not completely closing, just there is the valve of another baking oven to open.
When the Permission Levels that the submission of a more than baking oven vacuumizes are the same, host will sequentially be lined up and vacuumize,
And the evacuated state of higher permission is in when certain, it can jump the queue and carry out in advance, and it is lower to vacuumize permission, comes below.
2) host is lined up and is ordered according to the Permission Levels of 1, No. two baking oven 2 and No. three baking ovens 3 of No.1 baking oven, is come
Judge whether to open vacuum valve；
3) when being lined up, host sends a signal to sensor, so that vacuum tube 5 makes corresponding waiting movement, to prevent pipe
Road gas backstreaming.
Embodiment 2
An a kind of vacuum pump multiple devices system, including vacuum pump 4 and several baking ovens, the number of baking oven are 3, packet
1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 are included, 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 pass through branched pipe 6
It penetrates through and connects with vacuum tube 5, vacuum tube 5 and the perforation of vacuum pump 4 connect, on 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3
It is connected with vacuum valve.It selects any one between 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 for host, utilizes host
It is as follows to control vacuum pump 4, the method which vacuumizes, including following operating procedure:
1) demand for vacuumizing every independent 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3, according to Permission Levels
Successively sequence and fabrication order data, pass to host, Permission Levels are divided into following six kinds from low to high:
It is the grade for not allowing valve opening 1. not requesting out vacuum valve, is least privilege grade, i.e., is arranged without permission
Sequence need not also allow valve opening；
2. vacuum valve is opened in request, in this permission grade, multistage permission can be set again, and I grade of vacuum valve is opened in request, request is opened
II grade of vacuum valve, request open III grade of vacuum valve and request opens III grade IV of vacuum valve, are lined up according to the height of permission, at the same level
Be lined up according to sequencing；
3. vacuumizing, more baking ovens can vacuumize together in this same rank；
4. vacuum line waits, waited according to pipeline vacuum degree, or is established according to the vacuum degree appeared on the stage and will vacuumized
Mathematical model waited, to prevent the gas pumpback in pipeline；
5. pressure vacuumizes, stop the baking oven vacuumized, the baking oven with Permission Levels vacuumizes together；
6. valve closes delay, for highest permission, prevent valve from not completely closing, just there is the valve of another baking oven to open.
When the Permission Levels that the submission of a more than baking oven vacuumizes are the same, host will sequentially be lined up and vacuumize,
And the evacuated state of higher permission is in when certain, it can jump the queue and carry out in advance, and it is lower to vacuumize permission, comes below.
2) host is lined up and is ordered according to the Permission Levels of 1, No. two baking oven 2 and No. three baking ovens 3 of No.1 baking oven, is come
Judge whether to open vacuum valve；
3) when being lined up, the waiting movement of vacuum tube 5 is completed by the algorithm control in host, to prevent pipeline gas from returning
Stream.
For example, the Permission Levels of No.1 baking oven 1 are not request out vacuum valve, the Permission Levels of No. two baking ovens 2 are that request is opened
Vacuum valve, the Permission Levels of No. three baking ovens 3 are that valve closes delay, and such host is first to handle No. three bakings certainly after receiving information
Case 3 reprocesses No. two baking ovens 2, finally handles No.1 baking oven 1.
For another example, the Permission Levels of No.1 baking oven 1 are to vacuumize, and the Permission Levels of No. two baking ovens 2 are that vacuum is opened in request
Valve, the Permission Levels of No. three baking ovens 3 are to force to vacuumize, at this point, host can forcibly close No.1 baking oven 1, on No. three baking ovens 3
Vacuum valve opening is vacuumized, and then operates the order of No. two baking ovens 2, last operation No.1 baking oven 1 again.
For another example, the Permission Levels of 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 are that vacuum valve is opened in request, if No.1
1, No. two baking oven 2 of baking oven and No. three baking ovens 3 are opened as the grade that vacuum valve this Permission Levels are divided into is in request, then according to
The sequencing of request carries out queuing operation, if 1, No. two baking oven 2 of No.1 baking oven is different with the permission of No. three baking ovens 3, it is assumed that
No.1 baking oven 1 is that request opens I grade of vacuum valve, and No. two baking ovens 2 request out II grade of vacuum valve, and No. three baking ovens 3 are that vacuum valve is opened in request
III grade, then No. three baking ovens 3 are first handled, No. two baking ovens 2 are reprocessed, finally processing request opens I grade of vacuum valve.
For another example, the Permission Levels of 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 are to vacuumize, and host receives
After command request, 1, No. two baking oven 2 of No.1 baking oven and No. three baking ovens 3 can be vacuumized simultaneously.
By this operation, more baking ovens may be implemented and only need a vacuum pump 4 that can drive and complete highly effective drying, greatly
While reducing costs greatly, it will not be easy string chamber, the requirement of multiple devices difference vacuum degree can be met simultaneously.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
