| Num＝00 Speed＝01 Num?range?00-00 |
2. drawing parameter input
The user is provided with the drawing parameter by stirring code switch.
System's regulation, the drawing numbering must be 19 to the maximum since 0, totally 20 groups.
During input drawing numbering, defer to the principle that increases successively from small to large.If done 3 groups of drawings, then the user can to carry out the numbering input range of drawing next time be 0..3, promptly user's former numbering (0-2 covers former data) of can reforming on the one hand can be carried out drawing next time (being numbered at 3 o'clock) on the one hand.
3. the parameter input is determined
After the parameter input is finished, press " determining " key, system at first descends, display shows " Downing ... "Automatically stop behind the decline 30mm, display shows " Press Start to Run ", and the following institute in interface is not at this moment:
| System?Ready Press?Start?run |
4. startup drawing
Under system's ready state, by " startups " button, system begins to search for stress point, and screen display " Search Strength " at this moment is as follows:
| Search?Strength Please?wait... |
After system detects stress point, promptly begin drawing automatically, measure displacement and pulling force simultaneously, and on screen, show in real time.
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 is as follows:
| ?Max?129?N?0.3mm ?Cur?125?N?0.8mm ?Elapse?Time?12s |
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
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.
| Max?129?N?0.8mm 112?N?0.1mm 113?N?0.2mm 114?N?0.3mm |
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
