Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
See Fig. 1, a kind of electric ceiling curtain device, comprises serving 1, cord 2, serving motor 3 and batching motor 4, and controls the controller 5 of serving motor 3 and batching motor 4, is provided with support bar 6 below cord 2.Serving motor 3 and batching motor 4 are condenser type run asynchronous motor, and are undertaken spacing by mechanical trip position-limit mechanism, and controller 5 controls the operation of serving motor 3 and batching motor 4, thus make cord 2 accurately can move to ideal position.The stator winding of serving motor 3 and batching motor 4 is equipped with positive switch coil l1 and reversion coil l2, see Fig. 2.The mechanical trip position-limit mechanism of serving motor 3 and batching motor 4 can adopt prior art, as the journey controller of application number a kind of tube shaped electric machine disclosed in the Chinese patent of CN03232015.9, and for example application number a kind of chain-type tube shaped electric machine disclosed in the Chinese patent of 201520064346.8, form mechanical journey stop gear by the cooperation of teeth nut, collision block and travel switch and carry out stroke limit, concrete does not repeat them here.It is spacing, precisely spacing that two motors all adopt mechanical trip to carry out, and ensure that accuracy and the stability of system cloud gray model; And after adopting mechanical trip position-limit mechanism, main electronic component is all on controller 5, and controller 5 is not in hot environment, therefore more reliable.
Controller 5 can be mounted to the position being convenient to control, and directly controls the operation of serving motor 3 and batching motor 4; Can certainly be controlled by remote control, this Time Controller 5 has the signal receiving end receiving wireless control signal, and remote control can be remote controller, also can be smart mobile phone, panel computer etc.
The degree of fabric tensioning in cord 2 running and after arriving limit point or receiving halt instruction the tensioning degree of serving or cord all can regulate, concrete regulative mode will be described in more detail below; Two motors, in Installation and Debugging process or maintenance process, can be discharged band-type brake by ceiling blind simultaneously, and brake is decontroled, and facilitates Installation and Debugging and the maintenance of ceiling blind.
The control method of electric ceiling blind is as follows:
Controller 5 receives instruction and analyzes;
When performing cord 2 and launching order, serving motor 3 is as traction electric machine, and batching motor 4 is as stand-by motor, after serving motor 3 receives the starting command that controller 5 sends, unclamp band-type brake and start to rotate, cord 2 starts to launch gradually, now, batching motor 4 also unclamps band-type brake, and produces a reversal interlocking relay (the first damping force) and rotate with serving motor 3, and cord 2 launches gradually, when serving motor 3 runs to limit point, teeth nut on its journey controller at most arrives collision block, thus make handle top on collision block to the contact on travel switch, now serving motor 3 power supply is cut off and stops operating and band-type brake, now the electric current of serving motor 3 is 0, after controller 5 receives the power-off signal of the travel switch of serving motor 3, (controller 5 is provided with current detection module, when detecting that current of electric can judge to reach limit point from when becoming greatly 0) control batching motor 4 and reverse, batching motor 4 reverses and to stop operating after certain angle and band-type brake makes cord 2 be in tensioning state, or when controller 5 send cease and desist order time, controller 5 controls serving motor 3 and to stop operating and band-type brake, and controls batching motor 4 and reverse and to stop operating after certain angle and band-type brake makes cord 2 be in tensioning state.
When performing cord 2 and drawing order in, batching motor 4 is as traction electric machine, and serving motor 3 is as stand-by motor, after batching motor 4 receives the starting command that controller 5 sends, unclamp band-type brake and start to rotate, cord 2 starts to draw in gradually, now, serving motor 3 also unclamps band-type brake, and produces a reversal interlocking relay (the second damping force) and rotate with batching motor 4; When batching motor 4 runs to limit point, teeth nut on its journey controller at most arrives collision block, thus make handle top on collision block to the contact on travel switch, now batching motor 4 power supply is cut off and stops operating and band-type brake, now the electric current of batching motor 4 is 0, namely controller 5 controls serving motor 3 and reverses after receiving the power-off signal of the travel switch of batching motor 4, serving motor 3 reverses and to stop operating after certain angle and band-type brake makes serving 1 be in tensioning state; Or when controller 5 send cease and desist order time, controller 5 controls batching motor 4 and to stop operating and band-type brake, and controls serving motor 3 and reverse and to stop operating after certain angle and band-type brake makes serving 1 be in tensioning state.
Due to the sagging that the weight of cord 2 and support bar 6 causes in running, can by the dynamic tension regulating the damping force of stand-by motor obtain expection.See Fig. 2, by the positive switch coil l1 of stand-by motor and reversion coil l2 short circuit the shorted on both ends of shown two coils (on the Fig. 2), and between two coil shorted end and the common wire of two coils, add the first adjustable voltage (to start to exchange fire line L1 or L2 in shorted end, load between common wire connecting to neutral line N), the difference of the first adjustable voltage added by stand-by motor, dynamic tension is divided into several grades, be divided into 0 ~ 9 grade (adjusting knob can be set on controller 5 in the present embodiment, when needing to regulate, rotate adjusting knob), gear larger (or less), added first adjustable voltage value is larger, first damping force or the second damping force larger, during operation, cord 2 just draws tighter, thus regulate the tensioning degree of fabric in ceiling blind plant running process.Preferably, the first adjustable voltage is alternating voltage, by arranging controllable silicon on the circuit two coils being applied to the first adjustable voltage, regulates the size of the first adjustable voltage.
Hereinbefore, in the expansion or gathering process of cord 2, when stand-by motor stops, the tensioning degree of cord 2 or serving 1 can regulate: be divided into by maintenance tension force several grades (can arrange adjusting knob on controller 5, when needing to regulate, rotate adjusting knob), the adjustment maintaining tension force is realized by regulating the length of stand-by motor reversing time (i.e. reverse angle), stand-by motor reversing time longer (namely reverse angle is larger), the number of turns of reversion is more; The tension force be also simultaneously set to when stand-by motor reversion is tightened up also can regulate, and can artificially be turned down by converse rotating force, like this when the power of reversing pulls fabric or serving not, just stops, can ensureing that fabric or serving collapse tight effect like this.See Fig. 3, by vacant for one of them end in the positive switch coil l1 of stand-by motor or reversion coil l2, to add the second adjustable voltage (start to exchange fire between line L1 or L2, common wire connecting to neutral line N in shorted end and load) between another end and common wire in the positive switch coil l1 of stand-by motor or reversion coil l2, after ceiling blind plant running can be regulated to stop, stand-by motor reverses the tension force tightened up.Tension force when reversion being tightened up also is divided into several grades (can arrange adjusting knob on controller 5, when needing to regulate, rotate adjusting knob), and the power of gear larger stand-by motor reversion is larger.Tension force acting in conjunction when regulating stand-by motor reversing time (i.e. reverse angle) and reversion to tighten up is to regulate the tensioning degree of serving 1 or cord 2.Such as: maintenance tension force is set to maximum, now motor can reverse 1 circle in theory, tension force when then regulating stand-by motor reversion to tighten up, if tension force when stand-by motor reversion being tightened up also is adjusted to maximum (or minimum shelves), namely now the tension force of reversion when tightening up is maximum, and so stand-by motor will finally reverse 1 circle; If while maintenance tension force is set to maximum (or minimum shelves), tension force when stand-by motor reversion being tightened up is adjusted to time large shelves (or secondary little shelves), namely now the tension force of reversion when tightening up is not maximum, and so stand-by motor finally will reverse and to enclose less than 1.Same, preferably, the second adjustable voltage is also alternating voltage, also can be regulated by controllable silicon.
Owing to only controlling serving motor 3 and batching motor 4 by a controller 5 simultaneously, therefore the present invention is when ceiling blind Installation and Debugging or maintenance, serving motor 3 and batching motor 4 can be discharged band-type brake simultaneously, the brake of two motors be decontroled, thus facilitates Installation and Debugging or the maintenance of ceiling blind.And two motors adopt same controller 5 to control, run with same Single-chip Controlling two motors, reliability is higher, and synchronism is better.
