【正文】 measurement routine selflearning design works for the four states, Lowspeed closed state, the door properly closed state, low speed open state, the door properly opened state. The process flow diagram shows in Figure 5. Figure 5 Door wide selflearning flow chart V. EXPERIMENTAL RESULTS Elevator accidents usually occur in door systems, the door should not open and open is the most serious incident. The paper realizes the door machine’s control through the acquisition of d and q axis current. [7][8] The Maximum displacement of singledoor is 45mm, the door displacement and current experimental curve shown in Figure 6. When the door closed or pletely open, id is approximately 0, iq is as a fixed value. In process of the door open or closed,id small changes, iq changed greatly Because Forced to close capacity is Active power, therefore, large current iq. In this paper,force and coercion to force without forcing both cases experiments were done, through analysis of the current qaxis as shown in Figure the open process,Forced to close capacity is the load force, as the door after the first speed reduces, and the current increases and then decreases first while. In the closing process, the forced closing force is the driving force,the electrical load increases,the current also significantly increased. Figure 6 displacements and the current curve Figure 7 qaxis coercion to force and non VI. CONCLUSION Through the analysis of the experimental,using the permanent mag synchronous linear motor as drive motor, realized the elevator door to run the operation curve by default, and the door system is reliable,low system can also be used to Warehouse door and Home automatic door, but also can use the system to reform the existing elevator door and automatic door.
