AC elevator speed control difficulty in decelerating and crawling section can t real2ize permanent deceleration control. The rotor string resistance is very big in speed modulation on energy con2sumption ,the control circuit is complex ,and usually have some questions about breakdown and damage and soon. Introduced the converter in slant hole elevator system application , elaboratated the elevator energy conser2vation in frequency conversion and speed modulation. The travelling schedule control. The energy back cou2pling and the applies break process.Key words :conventor ;elevator ;frequency conversion and speed modulation ;travelling schedule control ;energyback coupling0 ,, ,1 ,1 2 ,3 ,1 ,,2 ,,, , , KT , ,,(1) , , , , , (2) , , (3) S , , (4) , ZJ T - 30 , PLC PLC , , (5) , ,(6) , , ,

Hall s sensor is sensitive to magnetic field utilizing Hall s effect of material. Be2cause it has the simply structure , the good dynamic characteristic and may carry on non - contact measuremerit . Apply it to product examination ,automatic control and products counting , its use not only satisfied theproduction need also enhance the production efficiency and the control precision.Key words :Hall s effect ; Hall s sensor ; application0 ,, ,R S T , IGBT ,U V W ,3 ZJ T - 30 - MSC ,,( / ) ,ZJ T - 30 - MSC / / :, PLC,- A1 PLC - A2 ,PLC - A1 PLC - A2 ( CCS ) ,, 4 PLC - A1 , 2004 10 ,1 , PLC ZJ T - 30 - MSC ,- A2 ; PLC - A2 , 30 % ,2 , PLC - A1 ,PLC - A2 , PLC - A1 , :[1 , ] , , .
