The right contact of door machine contact contact 14 is installed on the right door hanging plate 3 of a machine by door machine contact support 15, and left contact is installed on the door opener base plate 1 by door machine contact support 13.
Intermediate buffering block assembly 12 is installed between right door hanging plate 3 of a machine and the door machine left side door hanging plate 11, when making the elevator door-closing in-place, a door machine left and right sides door hanging plate does not clash into, and the vibrations can reduce the elevator door door-closing in-place time, make the motion of elevator door more steady, noise is littler.
Intelligent driven controlling system as shown in Figure 4 and Figure 5, dragging the door opening machine for elevator that the intelligent linear electric motor of pattern drives with the separate unit linear electric motors of Fig. 1 is that example is described below:
Door opening machine for elevator is driven by a line inductance electromotor (LIM).Secondary 2 of LIM is made up of a copper coin and a magnetic conduction steel plate, is installed on the machine bottom board 1, and be fixed.Elementary 4 of LIM is made up of armature core and three phase windings, is installed on the right door hanging plate 3 of a machine, moves with door.Three phase windings are done star connection, and three winding overhang U, V, W are connected to the inverter output end of controller.In addition, the door hanging plate has been installed photoelectric encoder, and its shaft extension end is connected with steamboat by a flexible clutch, and steamboat moves on door machine guide rail 8.Like this when the Room, when gate moves, photoelectric encoder rotates, and sends the impulse singla that two of A, B are 90 degree phase differences.These two signal controlled devices are used for the position and the sense of motion of detecting gate.The functional block diagram of intelligent driven controlling system as shown in Figure 4.Control unit wherein is exactly the CPU of a chip system (PSOC), maintenance among figure instruction be a 0V or+digital signal of 5V (representative " maintenance " or " normal operation " respectively), directly receive on the pin of CPU (joining No. 10 pin among Figure 12).When this instruction is " maintenance ", CPU sends " overhauling " signal (ginseng Figure 12 in No. 17 pin) by its pin to main frame, and the instruction (o.11 pin ginseng Figure 12) 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 12) of reading " opening the door " or shut the gate from main frame by another pin.CPU control inverter subsequently powers to LIM, moves on to the position until door, and sends out " open the door and put in place " or " and door puts in place " signal (the 16th and No. 15 pin among ginseng Figure 12) by other two pins respectively to main frame.Here, the signal that main frame sends or receives be 0V or+digital signal of 24V, and CPU receives or send be 0V or+digital signal of 5V, so the signal transmission between the two also needs a level shifting circuit.This circuit as shown in Figure 6 and Figure 7.
Two output signal A of photoelectric encoder and B at first indicate the sense of motion of door through phase discriminator shown in Figure 8.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 signal through frequency multiplier circuit shown in Figure 9.CPU reads position signal and direction signal (the 25th and No. 24 pin among ginseng Figure 12) by two pins.Position signal is an impulse singla, and its positive rise triggers the interruption of CPU; Have no progeny in the CPU response, the service direction of decision gate at first, the position numerical value of opposite house adds deduct 1 again.So the translation distance of the corresponding door of unit position numerical value is (П D/N2), wherein D is the diameter of steamboat on the photoelectric encoder shaft extension, and N is the resolution of photoelectric encoder, the pulse count that promptly whenever circle 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 5 is to the LIM power supply.The direct supply of inverter is obtained through three-phase diode rectification and capacitor filtering by three-phase 380V source of AC.Inverter is made of the IGBT of three-phase intelligence merit module (IPM).The driving 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 energizing signal (U of IPM by 6 pins
P, V

N) (ginseng Figure 12 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 shown in Figure 10 and Figure 11, low level is represented the IGBT conducting among the figure, high level represents that IGBT turn-offs.Here do not adopt any type of pulse duration modulation (PWM), because PWM can cause severe noise and electromagnetic interference.But, the triggering frequency of IGBT, just the line frequency of LIM can be regulated by CPU.Like this, LIM is operated in the constant pressure frequency conversion mode.This mode can not cause that magnetic circuit is saturated concerning the quite big LIM of electromagnetism air gap, but the thrust that can regulate LIM, thereby realizes the speed and the position control of elevator door.The service direction of LIM 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 10.Otherwise at closing time, U phase energizing signal hysteresis V is 120 degree mutually, V W 120 degree mutually that lag behind again mutually, as shown in figure 11.DC side at inverter has a current sensor, and its output is directly connected to (No. 1 pin among ginseng Figure 12) on the pin of CPU.CPU in-to-in low-pass filter carries out filtering to this electric signal, and the cutoff frequency of filter is about 100 times of the highest reverse frequency.And CPU utilizes in-to-in A/D converter sample rate current signal, calculates the three-phase instantaneous current of LIM then in conjunction with switching states.Realized time real detection the around electric current to LIM 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 detecting with hardware such as light film, baffle plates, CUP also will be by judging LIM running state (for example speed and electric current).In case discovery foreign matter, CPU will be controlled LIM 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 time real detecting gate the position.And detecting because of the external force effect oppositely when mobile, CPU will power to LIM 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, LIM 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 12) 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 running velocity curve of door, door, or the like.
Two linear electric motors shown in Figure 2 drag the door opening machine for elevator of the intelligent linear electric motor driving of pattern, different with Fig. 1 is: elementary 4 of two linear electric 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 linear electric motors secondary 2 be installed in respectively a machine bottom board 1 about on two linear electric motors secondary fixed seats 17 (linear electric motors secondary fixed seat 17 directly is connected with a machine bottom board 1), after linear electric motors 4 energisings, produce electromagnetic force between linear electric motors elementary 4 and the linear electric motors secondary 2 and promote a door machine left side, right door hanging plate 11,3 make left and right sides crank motion.Interlock steel rope 19 by interlock pulley set 7 makes their synchronous crank motions, realizes elevator open and close door.
It is identical that other structure and intelligent driven controlling system and separate unit linear electric motors drag the door opening machine for elevator that the pattern intelligent linear electric motor drives, and no longer heavily chats.
