【文章內容簡介】 e DSP control chip as a standard reference volume control. [4][5] When the door running, through the actual rate of speed circuit is established by the reference value and pared to the value derived from the signal input to the DSP in order to achieve the running speed of door control. IV. SYSTEM SOFTWARE DESIGN Door control program is an important part of system control, this control program is modular in design,each functional module and other modules when the shared variable shield, it can run independently, it is a good system for debugging and modification. This control procedure includes the main program and several subroutines。 the main function is to plete the door and control of operating parameters of the modified door operation by setting features such as running speed curve. Main program includes system initialization and main loop body position. Initialization includes initialization of the DSP and the external devices. Initialization is plete, enter the main loop, the system is running under the control of parameters set. [6]Door width 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 def
