At first, remote control transmitter transmits, and 13 pin that carry out being sent to after the decoding processing single-chip microcomputer U1 after receiver of remote-control sytem receives carry out decoding processing once more, and decoding finishes single-chip microcomputer according to the sign indicating number implication, carries out next step action.When remote controller emission be enabling signal the time, 16 human hair combing wastes of single-chip microcomputer go out a high level signal, door-rolling machine drives relay J D1 adhesive, door-rolling machine opens the door; When remote controller emission be when stopping gate signal, 14 human hair combing wastes of single-chip microcomputer go out a high level signal, door-rolling machine drives relay J D2 adhesive, door-rolling machine stops; When remote controller emission be that 13 human hair combing wastes of single-chip microcomputer go out a high level signal when closing gate signal, door-rolling machine drives relay J D3 adhesive, door-rolling machine is closed the door;
The realization of the function that automatically locks: the difficult point of the realization of the function that automatically locks is when lock, and this is the emphasis of this patent.Because single-chip microcomputer can not see whether door closes as the people is directly perceived, so need a signal to tell whether the monolithic gate closes the door on earth, whether can lock, and the hall probe principle is to utilize Hall effect, this circuit adopts Hall switch sensor.In the process of closing the door; The door body moves downward and drives the magnet of installing on the body and moves downward; When moving to the bottom, through the magnetic induction intensity enhancing of hall probe, when the magnetic induction intensity that adds surpasses hall probe operating point (being magnetic work threshold value Bop point); The output pin of hall probe becomes low level by high level, the output of 3 pin connectionist hall probes of single-chip microcomputer.Single-chip microcomputer 3 pin are known the lower limit of closing the door after detecting the output signal of hall probe, then through high level signal the positive-negative-positive Darlington transistor Q1 among the figure three are opened, the electric control lock power connection that connects on the CON1 terminal, and electric control lock is started working, and a door body is locked.
When controller received enabling signal, single-chip microcomputer 3 pin at first send a low level signal ended Darlington transistor Q1, and electric control lock and power supply break off, and magnetic force disappears, and promptly unblanked earlier, drove door-rolling machine and opened door sending signal then.If do not receive the enabling signal of remote control transmitter, the door body is opened, and the magnet on the door is away from hall probe; Weaken (when magnetic flux density is brought down below work threshold value Brp) through magnetic induction intensity; The output pin of hall probe has low level to become high level, and this level signal does not change before receiving the instruction of opening the door and just changes, and therefore is judged as illegal enabling signal; This moment, 9 human hair combing wastes of single-chip microcomputer went out high level signal; The relay J D5 adhesive of control remote alarm interface, remote alarm interface output, the attachable loudspeaker on the CON2 terminal or other security system.
