Description of drawings:

Fig. 1 is the wireless transmission functional-block diagram,

Fig. 2 is the controlled in wireless functional-block diagram.

Drawing explanation: 1, falling-threshold sensor, 2, the decline sensor, 3, the rising limit sensor, 4, rising sensor, 5, anti-oblique pull sensor, 6, the CPU coding, 7, wireless transmitter module, 8, the receiving key that resets, 9, receiver module resets, 10, the projector that resets, 11, wireless receiving, 12, the CPU decoder module, 13, CPU computing module, 14, the ULN2803 driver module, 15, carry out relay, 16, electric appliance control box, 17, motor, 18, combined aural and visual alarm.

The specific embodiment:

Specific embodiment, carrying out relay 15 is by the CD/MD vertical relay, CD/MD falling-threshold relay, always stop, about the row actuated small roadster, about the big sport car of row form, electric appliance control box 16 and motor 17 are prior aries, no longer describe, be connected with anti-oblique pull sensor 5 on the reel outer cover fixed end steel rope, rising sensor 4, rising limit sensor 1, the sensor can be exported electric signal respectively and be sent to CPU 6, after being input to wireless transmitter module 7, mouth launches (see figure 1) by CPU 6 codings towards periphery, wireless receiving module 11 in the high-frequency signal controlled device that wireless transmitter module sends receives, outputing to CPU computing module 13 after mouth output is decoded by CPU decoder module 12 handles, through CPU computing module 13 after mouth connect with ULN2803 driver module 14 respectively by lead, ULN2803 driver module mouth is communicated with execution relay 15 respectively, the long closed contact of carrying out on the relay inserts in the loop of AC contactor voltage coil in the electric appliance control box 16, connect motor 17 respectively by the electric appliance control box mouth, during normal operation, lifting/ lowering sensor 4,2 and anti-oblique pull sensor 5 equal no signals export, the controller testing is normal, the CD/MD motor, greatly, the actuated small roadster motor is carried out lifting respectively, about operation work, when the electric block liter, when falling ultralimit or tiltedly drawing angle to transfinite value, the displacement of this moment is passed to liter by transferring structure, sensor and anti-oblique pull sensor are fallen, the electric signal that converts thereof into is separately delivered to wireless transmitter module 7, wireless transmitter module 7 high-frequency signal of spatial emission behind CPU coding towards periphery of encoding, wireless receiving module 11 receives that corresponding signal decodes through CPU in the controller, after the judgement, reach CPU 13, further computing, time-delay, handle, reach the ULN2803 driving circuit, thereby promote to carry out the CD/MD vertical relay of relay 15, a left side, the right lateral actuated small roadster, a left side, the big sport car motor outage of right lateral, combined aural and visual alarm 18 sound and light alarms simultaneously.

If take place because of after the ac contactor contact adhesion, the CD/MD motor that can continue 17 li of mobile motors continues the work of hoisting, driving device on the rising limit sensor 3 still can continue to move, thereby promoting sensor makes it export the transducing signal that cuts off general supply immediately, judging through each CUP that motor cuts off the power supply immediately quits work, this moment, electric block will all cut off the power supply, sound and light alarm sends the sound of high-decibel, remind the operator to note, if recover electric block work, must change the AC contactor of repairing adhesion earlier, push reset switch 8 or send reset signal with the emission remote controller that resets, receiver module 9 is sent to CPU 12 through resetting, 13, it is reinitialized after, electric block can be reworked.
