Further, described shutter motor is three-phase four-wire system motor.
The beneficial effects of the utility model are: structure is simple, arrange without complicated circuit, with low cost; Simple to operate, user switches automatic control mode and manual control mode easily by universal seclector, and only simply need set time switch or operation start switch can realize shutter roller shutter (motor rotating forward) and put curtain (motor reversal) control; Simultaneously safe and reliable, due to the setting of limit switch, shutter there will not be pulleying or crosses the danger of putting, and has accomplished omnibearing safety assurance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of three-phase four-wire system greenhouse roller circuit for controlling motor, comprises a universal seclector SA, and universal seclector SA comprises three gears, respectively corresponding automatic control circuit, manual control circuit and rest potential, described automatic control circuit comprises time switch SK and auxiliary relay KA, very first time relay K T1 and the second time relay KT2 is connected with between time switch SK and auxiliary relay KA, and very first time relay K T1 and the second time relay KT2 are connected with two inputs of auxiliary relay KA respectively, two outputs of auxiliary relay KA connect rotating forward contact and the reversion contact of motor main circuit M respectively, and the rotating forward contact of very first time relay K T1 corresponding motor main circuit M, the reversion contact of the second time relay KT2 corresponding motor main circuit M, described manual control circuit comprises a rotating forward control section and a reversion control section, described manual control circuit rotates forward control section and comprises the first starting switch SB1 connected successively, first interlock switch S1, first limit switch QA1 and the first contactor KM1, described manual control circuit reversion control section comprises the second starting switch SB2 connected successively, second interlock switch S2, second limit switch QA2 and the second contactor KM2, first interlock switch S1 and the second interlock switch S2 is closed type switch, and the first starting switch SB1 when closing the second interlock switch S2 disconnect, when second starting switch SB2 closes, the first interlock switch S1 disconnects, first limit switch QA1 is positioned at booth top, and the second limit switch QA2 is positioned at booth bottom, and the first limit switch QA1 is connected with the rotating forward contact of motor main circuit M, and the second limit switch QA2 is connected with the reversion contact of motor main circuit M.In the utility model, shutter motor is three-phase four-wire system motor.
The course of work of the present utility model is as follows:
When selecting automatic operation, the opening time of very first time relay K T1 and the second time relay KT2 is first set respectively on time switch SK and opens duration, opening time and roller shutter (motor rotating forward) opening time and roller shutter duration, the opening time of the second time relay KT2 and the putting curtain (motor reversal) time started and putting curtain duration of unlatching duration correspondence shutter of opening the corresponding shutter of duration of very first time relay K T1.After having set, universal seclector SA is dialed to the automatic control gear of corresponding automatic control circuit, the automatic control of shutter motor can be realized.
During manual operation, universal seclector SA is allocated to the Non-follow control gear of corresponding manual control circuit, open the first starting switch SB1 rotated forward for controlling motor, second interlock switch S2 disconnects immediately, thus manual control circuit reversion control section disconnects, motor main circuit rotates forward contacting, motor starts to rotate forward, shutter starts roller shutter, first limit switch QA1 and the second limit switch QA2 is normally closed switch, when shutter turns to booth top, first limit switch QA1 is triggered disconnection, motor stalls, thus shutter completes roller shutter operation.In like manner, when opening the second starting switch SB2 for controlling motor reversal, what can complete shutter puts curtain operation, and when shutter turns to booth bottom, the second limit switch QA2 is triggered disconnection, motor stalls, shutter stopping roller shutter.First contactor KM1 and the second contactor KM2 is mainly used in amplified current, protecting control circuit.
And when universal seclector SA dials to rest potential, control circuit is in static off-state, motor main circuit M is not had an effect.
