Disconnected once tongue tube just sends an electric signal to controller, and the number of times of tongue tube break-make is exactly the number of turns that motor is turned over, control
The number of turns that device is rotated to motor in the unit interval is calculated, you can the rotating speed of motor is obtained, by the rotating speed calculated and motor
Rated speed be compared, such as exceed rated speed certain value, then door curtain be in fall condition, controller be driving electromagnetic system
Dynamic device carries out brake, and reel is checked, and prevents door curtain from continuing to decline.
Further, the permanent-magnet steel is provided with multiple, and is distributed along motor shaft even circumferential.Each permanent-magnet steel is close dry
Reed pipe once can send an electric signal to controller, and motor, which rotates a circle, can send multiple signals, be easy to accurate control.
Further, the controller is provided with single chip machine controlling circuit.Singlechip technology is ripe, cheap, more general.
Further, the transmission mechanism is chain-drive mechanism.Chain-drive mechanism is conventional transmission mechanism, simple in construction,
It will not skid.
Further, in addition to control button, control button and the controller electrical connection.For directly controlling door roller.
Further, the electromagnetic brake is dead electricity band-type brake type electromagnetic brake.
Further, the electromagnetic brake is dry type electromagnetic brake.Dry type electromagnetic brake price is relatively inexpensive.
The beneficial effects of the utility model are：It is accurate that the revolution of door roller motor is carried out using permanent-magnet steel and tongue tube
Count, judge whether motor exceeds the speed limit, so as to judge whether door curtain quickly falls, when door curtain surprisingly quickly falls by electromagnetic system
