The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model as shown in Figure 1, be a kind of remote-control anti-theft Glass fiber reinforced plastic garage door, the door body is connected and composed by two parts, body 1 is fixed on the wall to the doorstep, Xiamen body 2 is with body is hinged to the doorstep, fixedly connected with steel wire 3 respectively in body 2 two sides in Xiamen, the every steel wire other end is walked around fixed pulley 4, be connected with a plumbous heap 5 respectively, a support 6 devices are installed on door body top, fixed pulley 7 is installed on this device, as shown in Figure 2, draw high part steel wire 8 one ends and be connected with Xiamen body 2, the other end is wrapped on the power transmission shaft 10 that has a spiral race 9, and the spiral race is a variable-diameter structure, be fixed on the less relatively diameter of axle power transmission shaft by big footpath helicla flute spiral surrounding, power transmission shaft is connected with motor main shaft, and body 2 bottoms in Xiamen are installed with electronic lock 11, drive motors 12, electronic lock 11 is controlled by a circuit remote control.Manual clutch 13 is installed between power transmission shaft 10 and the motor main shaft, and as shown in Figure 4, a door external surface adheres to fixing one deck frp layer 14.

Described circuit remote control is by signal projector, and signal receiving device, control circuit, power circuit and executive component are formed, and as shown in Figure 6, executive component is two relay J that are connected in parallel on the drive motors power line _C, J _M, as shown in Figure 3, relay J wherein ₁Constant open contact, pressing microswitch WK ₁, relay J _C, relay J _MConstant close contact be connected in series; J ₂Constant open contact, relay J _M, relay J _CConstant close contact be connected in series; As shown in Figure 5, control circuit repeat circuit J ₁, J _S, J ₂, J ₃, J ₄Be connected in parallel in the DC circuit of a 24V, wherein J ₁, J _S, J ₂Output and J ₁Constant open contact, signal receiving key XH, J ₃Constant open contact, J ₂The parallel circuit series connection that constitutes of constant open contact; J ₁, J _SInput and J ₂Constant close contact, normally closed switch XK ₁Series connection; J ₂Output and J ₃, J ₁, J ₄Constant close contact series connection, normal open switch XK ₂With J ₂The constant open contact parallel connection after again with J ₂Input connect; Optoelectronic switch GD and J ₃The constant open contact parallel connection again with J ₄Constant close contact, J ₃And J _CConstant close contact series connection; Lower position switch XK ₃With J ₄Series connection.

Signal projector of the present utility model, signal receiving device adopts prior art, and its signal receiver can be encrypted, and non-local signal does not receive in advance, and is antitheft.Various electric elements of the present utility model are all through selected, and the conducting contact is good, and are sensitive reliable.Misoperation is stopped in the interlocking of control loop the two poles of the earth.

One, circuit of the present utility model constitutes:

As shown in Figure 7 should control system general supply adopt the single-phase 220V power supply of 50HZ, so easy to use.

By step-down transformer (25W) and rectifier cell, produce the working power of two groups of dc sources (each group of 24V and 12V), and have leakage switch as DC control circuit.The whole control system comprises a following long-pending controlling unit.

1, the control of opening the door: under normal circumstances, finish the process of opening the door in 8 seconds.

2, the overload protection that opens the door: if having a mind to other factor, Ku Men does not open, or does not finish the process of opening the door in 8 seconds.Automatically stop the 9th second from the signal emission, prevents burn-down of electric motor.Again operation after waiting to remove.

3, close gate control.

4, anti-contingency control: in the process of closing the door,, stop the process of closing the door immediately automatically, and be automatically converted to the process of opening the door if having under people or other object access doors.

550W single-phase capacitance reversing motor little power consumption is adopted in drive motor.

Two, the utility model circuit working principle:

1, open the door: after signal receiver was received signal, XH1.2 connected, the J adhesive of switch on, and its constant open contact is self loop self-locking, and send electricity to electromagnetic lock DT simultaneously, after electromagnetic lock is opened fully, pressing microswitch WK, A.C. contactor J _CThe energising adhesive, its constant open contact closure, motor power by 1,3 terminals, forward running, Ku Men opens, and overall process is launched in 8 seconds from signal and is finished XK ₁End, XK ₂Logical.

2, the overload protection that opens the door: because some unexpected factor, signal emission back door is not opened or is not finished the process of opening the door in 8 seconds, time relay J _SConstant open contact in the time of the 9th second, hold and open, cut off J one by one ₁, J _CPower supply, motor is out of service.

3, close the door: because the storehouse door is under opening, upper limit position switch XK ₁Disconnect, and XK ₂Be closed.So at the contact of signal receiver XH _1,2After the conducting, has only J ₂Coil form path, J ₂Adhesive make its constant open contact closure, respectively with XK ₂And XH ₁₂Parallel connection forms self-locking state, J ₂Another constant open contact and A.C. contactor J _mCoil series connection, make J _MEnergising adhesive, and J _MConstant open contact make motor be subjected to electricity from 1,2 terminals, transhipment row only, Ku Men closes.When the storehouse door is handled closed condition, lower position switch XK ₃By pressing, because of it is connected on relay J ₄Wire loop in, the institute so that J ₄The energising adhesive, J ₄Constant close contact be connected on J ₂Wire loop in, thereby make J ₂Outage, J successively _MOutage, motor is out of service.

4, injury protection: in the process of closing the door, J _MThe constant open contact closure, make optoelectronic switch GD be in readiness for operation.If have under people or other object access doors this moment,, thereby make relay J through the photoelectric sensor triggering optoelectronic switch GD of door limit installing conducting ₃The coil electricity adhesive, J ₃Constant close contact be connected on J ₂Wire loop in, thereby make J ₂Outage discharges, and J ₃A constant open contact again with XH _1,2So parallel connection is J ₁The adhesive of switching on immediately reopens door, prevents that contingency from taking place.
