5. drawing process
During drawing, the pulling force of the first behavior drawing maximum and corresponding displacement thereof on the screen, second row shows the pulling force and the displacement of current drawing, the third line demonstration drawing is the time of usefulness (second).The interface as shown in Figure 5.
6. drawing is finished
When the system discovery pulling force begins to descend (pulling force of current point be maximum pull 20%), stop drawing, getting maximum value is the drawing pulling force.In order to prevent that abnormal conditions from occurring, system has increased some preventive action simultaneously:
When system does not find stress point all the time, after drawing runs to limit switch, stop drawing, prompting " Not find streng ".
When system does not find the pulling force drop point all the time, and motor range stops drawing, prompting " Not find streng " when reaching 30mm.
When system does not find the pulling force drop point all the time, and after drawing runs to limit switch, stop drawing, getting maximum value is the drawing value.
After drawing process is finished, show the drawing end product, point out the user to press " affirmation " key simultaneously and carry out next step operation.
7. drawing data are checked
Referring to Fig. 6, system has power down and preserves memory, and the data of drawing all are saved.The user can be after the motor playback, by " checking " button, the data number that system requirements user input will be checked, after input is finished, promptly show this group data by " determining ", if data can be carried out page turning by " affirmation " key and check that any time can be returned the interface that the requirement user imports the numbering that will check by " checking " once more more than a screen.
8. report printing
After drawing was finished, the user can be printed the drawing result by mini-printer.
The user is after the motor playback, and by " checking " button, the data number that system requirements user input will be checked can print the drawing data by " printing " at this moment.After printing is finished, can return by " checking " once more
9. data upload function
The drawing instrument is furnished with the RS232C interface, can carry out communication with the supporting upper computer software of drawing instrument.By upper computer software, can be with the data extract in the drawing instrument to computer and carry out various processing.
(2) drawing instrument upper computer software operation instruction
Drawing instrument upper computer software is a drawing instrument software kit, and function is to extract data from the drawing instrument, and data are generated data, curve report printing output.Software can run under Win98, Win2000, the WinXP operating system.
Setup.exe file in the operation mounting disc, install software.From the operation " drawing instrument data handling system " down of Window ' s desktop " ", " program ", " drawing instrument upper computer software " menu, software is carried out the back and is shown main interface after the installation.
