INTRODUCTIONThe traditional elevator door, warehouse door and civil came door-opening always drove by motor, because crane is a straight-line motion electromechanical integration device of frequent reciprocating,not only its operation and good safety requirements, but the smooth operation and low noise.Because the door is straight-line motion with reciprocating movement,the designation of a mechanical device,which transition the rotary motion of the motor to straight-line motion needed to realize the door open/close,is necessary.1 At present elevator door market in domestic,drive motor mostly adopt AC asynchronous motor or linear motor, due to the high speed,position and difficult control of the AC asynchronous motor,it must have slow institutions contains belt or gear transmission etc,which make its structure complex,efficiency lowly,noisy and the performance of speed poorly. Though the performance of speed of linear motor is easy,but for the existence of commentator,the reliability is poor,and easy to produce electromagnetic interference and spark,also need DC electrical source,difficulty to maintain.If using a PMLSM as drive motor,can save the transmission mechanism between motor and the gate,direct driving gear for linear motion,improve the reliability and safety of the door.This paper introduce the elevator door is using a PMSLM as drive motor.The mechanical structure drawing shown in figure 1, D1 and D2 are connected by a belt,through the PMLSM motor to realize two doors synchronous open/close.Systems control circuit adopts the TMS320LF240X TI Company LF2407 series as control chip,combining with intelligent power module IPM,to realize the door stable operate according to the curve set.Figure 1 Mechanical structure diagram of elevator doorII. CIRCUIT CONTROL SYSTEM A. Motor structure and optimization designTABLE I. THE SPECIFIC PARAMETERS OF THE PMLSMThis paper used Finite element software of Magnet to modeling the PMLSM. Prototypes structures are short primary and long secondary in unilateral,primary using scores slot concentrated winding form.The specific parameters of the PMLSM as shown in table 1.B. Hardware circuit design of the control systemThe hardware structure of control system is shown in figure 2;mainly include controller,SPWM,signal generator,rectifier circuit,intelligent power module IPM and sensors, etc. The controller selects and uses the TI Companys TMS320LF2407, 2407 has built-in module and pulse coding capture circuit, which can produce PWM waves.Intelligent power module IPM uses Fuji Companys 6MBP15RH060,to simplify the power circuit design by the built-in drive circuit.Control systems designation is mainly revolves control chip 2407 and intelligent power module IPM, using hall current sensor monitoring electric current on real-time, the current signal sent to DSP control chip to current peculiar protection.23 Adopting photoelectric encoder detecting the doors operating position and speed.Figure 2 control system handware structureC. System controller chart The control system use feedback control on three close loops: the position P,velocity V,and current I, diagram of system controller block as shown in Figure 3. The control process is,first of all, compare location P measured by optical encoder and position command P*,then find the speed command value V* by the position controller,the signal by compared V with V* after the speed controller find the current vector command I; detected motor current Ia and Ib by current sensor,then through the adder add Ia and Ib obtain Ic,then after coordinate transformation into a q-axis and d axis current of the motor current to achieve closed-loop negative feedback control.Compare speed V measured by the optical encoder and speed command V* to realize the negative feedback of motor speed.The experimental results show that the controller is easy to implement on the elevator door control and debugging.Figure 3 system controller chartIII. DOOR OPERATION CURVE DESIGNDoor operating curves shown in Figure 4， The figure for the single horizontal stroke fan elevator door, the vertical axis for the single fan speed elevator door. Above the x-coordinate for closes the running status curve, underneath for opens the running status curve. The figure shows the Door speed run is not run as a linear process of acceleration or deceleration, but to run as an S-shaped curve. Figure 4 Machine running curveThis section first run curve discrete, divided into m sampling points, and then set corresponding to each sampling time and speed, the sampling rate corresponds to the value of time and stored in the DSP control chip as a standard reference volume control. 45 When the door running, through the actual rate of speed circuit is established by the reference value and compared to the value derived from the signal input to the DSP in order to achieve the running speed of door control.IV. SYSTEM SOFTWARE DESIGNDoor 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 complete 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 composition. Initialization includes initialization of the DSP and the external devices. Initialization is complete, enter the main loop, the system is running under the control of parameters set. 6Door width measurement routine self-learning design works for the four states, Low-speed 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 self-learning flow chartV. EXPERIMENTAL RESULTSElevator accidents usually occur in door systems, the door should not open and open is the most serious incident. The paper realizes the door machines control through the acquisition of d and q axis current. 78 The Maximum displacement of single-door is 45mm, the door displacement and current experimental curve shown in Figure 6. When the door closed or completely 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 q-axis as shown in Figure 7.In 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 curveFigure 7 q-axis coercion to force and nonVI. CONCLUSIONThrough the analysis of the experimental,using the permanent magnet synchronous linear motor as drive motor, realized the elevator door to run the operation curve by default, and the door system is reliable,low noise.The 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.REFERENCES1 Ke Wang, Liming Shi, Yaohua Li and Jinwei He.
