Steel wire rope stretching device 19 is installed on the right link plate 3 of a machine, and this tensioning apparatus makes a machine wire rope increase tighter, more compact structure.
Intelligent driven controlling system as shown in Figure 3 and Figure 4, the permanent magnetic linear synchronous motor door opening machine for elevator that drags pattern with the separate unit linear electric motors of Fig. 1 is that example is described below:
Door lifter is driven by a permanent magnetic linear synchronous motor (PLSM).Secondary 2 of PLSM is made up of stainless steel tube, clavate iron core and annular permanent magnet, is installed on the machine bottom board 1, and be fixed.Elementary 4 of PLSM is made up of three phase windings, hall position detector and shell, is installed on the right door hanging plate 3 of a machine, moves with door.Three phase windings are done Y-connection, and three winding overhang U, V, W are connected to the inverter output end of controller.When the Room, when gate moves, the hall position detector can detect the displacement of door, and sends the pulse signal that two of A, B are 90 degree phase differences.These two signal controlled devices are used for the position and the direction of motion of detecting gate.The theory diagram of intelligent driven controlling system as shown in Figure 3.Control module wherein is exactly the CPU of a chip system (PSOC), maintenance among figure instruction be a 0V or+data signal of 5V (representative " maintenance " or " normal operation " respectively), directly receive on the pin of CPU (joining No. 10 pin among Figure 11).When this instruction is " maintenance ", CPU sends " overhauling " signal (ginseng Figure 11 in No. 17 pin) by its pin to main frame, and the instruction (o.11 pin ginseng Figure 11) of reading " opening the door " or shut the gate from a local switch by another pin.Otherwise when " normal operation ", CPU sends " it is invalid to overhaul " signal to main frame, and the instruction (No. 18 pin ginseng Figure 11) of reading " opening the door " or shut the gate from main frame by another pin.CPU control inverter subsequently powers to PLSM, moves on to the position until door, and sends out " open the door and put in place " or " door-closing in-place " signal (the 16th and No. 15 pin among ginseng Figure 11) by other two pins respectively to main frame.Here, the signal that main frame sends or receives be 0V or+data signal of 24V, and CPU receives or send be 0V or+data signal of 5V, so the signal transmission between the two also needs a level shifting circuit.This circuit as shown in Figure 5 and Figure 6.
Two output signal A of position detector and B at first indicate the direction of motion of door through phase discriminator shown in Figure 7.When opening the door, signal A anticipating signal B90 degree is so direction signal is always low level; Otherwise at closing time, signal A delay signal B90 degree is so direction signal is always high level.Secondly, signal A and B improve the precision of position signalling through frequency multiplier circuit shown in Figure 8.CPU reads position signalling and direction signal (the 25th and No. 24 pin among ginseng Figure 11) by two pins.Position signalling is a pulse signal, and its rising edge triggers in the interrupts of CPU response of CPU and has no progeny, the traffic direction of decision gate at first, and the position numerical value of opposite house adds deduct 1 again.So, the umber of pulse that the translation distance of the corresponding door of unit position numerical value and signal A or B send.
Intelligent driven controlling system is that the inverter of being made up of three phase mains, rectification module and Intelligent Power Module IPM by as shown in Figure 4 is to the PLSM power supply.The dc source of inverter is obtained through three-phase diode rectification and capacitor filtering by three-phase 380V AC power.Inverter is made of the IGBT of three-phase intelligence merit module (IPM).The drive circuit that comprises kinds of protect circuit and IGBT among the IPM.Last Unit three road (U+, V+ and W+) of IGBT need the 15V power supply power supply of three isolation, down the insulating power supply power supply of the shared 15V in Unit three road (U-, V-and W-).CPU sends the triggering signal (U of IPM by 6 pins P, V P, W P, U N, V N, and W N) (ginseng Figure 11 in the 6th, 7,8,20,21 and No. 22 pin), after light-coupled isolation, control the turn-on and turn-off of six IGBT unit of IPM U+, V+, W+, U-, V-and W-respectively.Each IGBT conducting 120 degree according to the order of sequence in an electric cycle, as Fig. 9 and shown in Figure 10, low level is represented the IGBT conducting among the figure, high level represents that IGBT turn-offs.Here do not adopt any type of pulsewidth modulation (PWM), because PWM can cause severe noise and electromagnetic interference.But, the triggering frequency of IGBT, just the frequency of supply of PLSM can be regulated by CPU.Like this, PLSM is operated in the constant pressure frequency conversion mode.This mode can not cause that magnetic circuit is saturated concerning the quite big PLSM of electromagnetism air gap, but the thrust that can regulate PLSM, thereby realizes the speed and the Position Control of elevator door.The traffic direction of PLSM is also controlled by CPU.When opening the door, leading V 120 degree are mutually believed in the triggering of U phase, and the leading again mutually W of V is 120 degree mutually, as shown in Figure 9.Otherwise at closing time, U phase triggering signal hysteresis V is 120 degree mutually, V W 120 degree mutually that lag behind again mutually, as shown in figure 10.DC side at inverter has a current sensor, and its output is directly connected to (No. 1 pin among ginseng Figure 11) on the pin of CPU.The low pass filter of CPU inside carries out filtering to this signal of telecommunication, and the cut-off frequency of wave filter is about 100 times of the highest reverse frequency.And CPU utilizes inner A/D converter sample rate current signal, calculates the three-phase transient current of LIM then in conjunction with switching states.Realized time real detection the to the PLSM winding current like this, if overcurrent condition takes place, CPU will turn-off all unit of IPM at once, recover original triggering state again after waiting electric current to fall back to allowed band.
In the process that elevator door cuts out, if foreign matter blocks door, except using up hardware such as curtain, baffle plate detect, CUP also will be by judging PLSM running status (for example speed and electric current).In case discovery foreign matter, CPU will be controlled PLSM inverted running (action of promptly opening the door) at once, and guarantee that impact to foreign matter is less than 150N.
Open or close when putting in place when elevator door, CPU turn-offs all unit of IPM, and the position of detecting gate in real time.Reverse when mobile when detecting because of the external force effect, CPU will power to PLSM by inverter again, will keep door to be in out like this or close the state that puts in place.But the thrust that this moment, PLSM produced is about 150N, and like this, car door is shut or opened to the foreign compulsion that allows to surpass 150N.
At last, CPU also carries out RS232 serial communication (the 26th and 27 pins among ginseng Figure 11) by its two pins and a hand held debugger.Like this, when installing or overhaul elevator, can use the hand held debugger that controller is provided with some necessary parameter, for example, the shift motion of the speed of service curve of door, door, or the like.
Two linear electric motors shown in Figure 2 drag the permanent magnetic linear synchronous motor door opening machine for elevator of pattern, different with Fig. 1 is: elementary 4 of two permanent magnetic linear synchronous motors are installed in respectively on right door hanging plate 3 of a machine and the door machine left side door hanging plate 11, two permanent magnetic linear synchronous motors secondary 2 be installed in respectively a machine bottom board 1 about on two permanent magnetic linear synchronous motor secondary fixed seats 16 (permanent magnetic linear synchronous motor secondary fixed seat 16 directly is connected with a machine bottom board 1), after permanent magnetic linear synchronous motor 4 energisings, produce electromagnetic force between permanent magnetic linear synchronous motor elementary 4 and the permanent magnetic linear synchronous motor secondary 2 and promote a door machine left side, right door hanging plate 11, move back and forth about 3 works.Interlock wire rope 18 by interlock pulley set 7 makes their synchronous reciprocating motions, realizes elevator open and close door.
It is identical that other structure and intelligent driven controlling system and separate unit permanent magnetic linear synchronous motor drag the pattern permanent-magnet synchronous linear motor door-opening machine, no longer heavily chats.
