Overlap computer controlled pneumatic servo valve of measurement
Printing, archiving and retrieval, and other functions designed to help process the file print processing efficiency to improve the servo valve,[link widoczny dla zalogowanych], a secondary means. Save and retrieve measurement results is matching the needs of the slide valve vice, but also to facilitate the quality of the statistical processing conditions. The system also has a complete set of help features,[link widoczny dla zalogowanych], in addition to instructions for use, common fault diagnosis, also joined the operation prompt,[link widoczny dla zalogowanych], and the operation of the order of the software limit, to a large degree of NN Lian Hang NYJ end adjustments have been recorded in the displacement point 』J a sequence valve Il chisel volume: A, B, c, DIl side Wataru J. Like the Office of u,,, AI 'll return to the first side of the mouth to find the end position adjusted returns measured starting point JJ to find the third side port l lI I return to the measurement point to eliminate the gap in the Australian IJ Il 4:00 displacement pressure of the second test to find port II 4 measuring the displacement pressure lll l 4 fourth side to find the displacement pressure port lI. . . . . . . . . . . . . . . . . . . . . . . JI measuring the displacement of a 4 l pressure measurement in Figure 8 the block diagram superimposed 4 Shaodong to the other: the amount of computer controlled pneumatic servo valve composite 57 on the measuring method of improving the operability of the system. 3.2 Design of worker threads than the main thread of all threads for the worker threads, worker threads and worker threads are divided into user interaction (UserInter-face) thread. 1) The thread stepper motor stepper motor drive with high and low pressure, through the stepper motor control and activate the suspended thread to control the motor start and stop, the circular three-phase six-shot pulse distributor implemented in software. The driving process is shown in Figure 9: Figure 9 P stepper motor driver block diagram of a \2) The detection of stable pressure measurements in the thread switching the pneumatic valve port will cause pressure instability, and should test the stability of pressure. This is the most time-consuming measurements, it uses a worker thread for processing, the pressure of dealing with the cycle of collection and comparison are in the background, it will not affect the interaction between user and program 4 Conclusion 1) A PC- As the host computer,[link widoczny dla zalogowanych], can increase the data processing capacity, the operability of the system, real-time monitoring capabilities have been enhanced. Mexico 58 - 12 volumes falling Fort ink 2) Overlap Accuracy: a valve ± 0.75,[link widoczny dla zalogowanych], two valves ± 0.5, to meet the practical requirements.
