Detailed description of the invention

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.

As shown in Figure 1, a kind of underground garage automatic door controller, comprise single-chip microcomputer, also comprise the power module, illuminant module and the Ground induction coil module that are electrically connected described single-chip microcomputer input, and be electrically connected display module, the gate control module of single-chip microcomputer output and prevent pounding car module, under the induction coil in described Ground induction coil module is embedded in the road surface before gate, receive road surface oscillator signal, the photo-sensitive cell of described illuminant module is arranged on gate, receives lights of vehicle signal.

As shown in Figure 2, the chip of ATC89C52 series that what single-chip microcomputer was selected is, its minimum system is meat and potatoes in single-chip microcomputer connecting circuit, and it is mainly made up of power circuit, reset circuit, oscillating circuit three part.

The major function of power circuit is to single chip circuit continued power, and reset circuit is that function is electrification reset in order to guarantee circuit stability reliably working in microsystem.The normal need of work power supply of general microcomputer circuit is 5V ± 5%, i.e. 4.75 ~ 5.25V.Because microcomputer circuit is sequential digital circuit, it needs stable clock signal, therefore when power supply electrifying, only have when VCC more than 4.75V lower than 5.25V and crystal oscillator steady operation time, reset signal is just removed, and microcomputer circuit starts normal work.In oscillating circuit, XTAL1 and XTAL2 is respectively the input and output of sign-changing amplifier.This sign-changing amplifier can be configured to sheet internal oscillator.Stone crystal oscillator swings and all can adopt with ceramic oscillation, because a machine cycle contains 6 period of state, and each period of state is 2 cycles of oscillation, so a machine cycle has 12 cycles of oscillation, if the frequency of oscillation of external quartz oscillator is 12MHZ, a cycle of oscillation is 1/12us, so a machine cycle is 1us [5].

The circuit design of Ground induction coil module is divided into two parts, Part I sends square-wave signal to Part II, as shown in Figure 3, Part I adopts capacitive feedback bikini oscillator, the waveform exported from oscillating circuit becomes square wave through shaping circuit, send signal to Part II from D port, the inductance value of the ground induction coil in the design is 100uH-150uH when not having car, has car to reduce to about 50uH through out-of-date.

When the signal of square wave is sent to Part II by Part I, as shown in Figure 4, ripple signal becomes low and high level signal through the port IN input of chip LM567CH through process, then exports from port OUT, sends single-chip microcomputer to by the port P32 of single-chip microcomputer.

The photo-sensitive cell of described illuminant module is photocell, receive illumination and changed into the signal of telecommunication, illuminant module is spare module, when induction of signal module does not sense signal, illuminant module will play a role, as shown in Figure 5, utilization be photronic operating principle, during unglazed photograph, illuminant module is in off-state, and Q1, Q2 not conductings, now do not play a role, when photocell is subject to illumination, produce higher electromotive force, illuminant module will change state, starts working, Q1, Q2 conducting, plays a role and reaches the effect of needs.

Described display module is dot matrix screen, as shown in Figure 6, connects dot matrix show word by two chip block expansion ports, and by display word to client's signal, the whether successful sensed signal of perception oneself, then makes corresponding measure, make it enter garage.

Described gate control module comprises rotary gate and stepper motor, the rotation of driving stepper motor rotary gate, as shown in Figure 7, gate control module selects rotational angle and the direction of ULN2003A chip controls stepper motor, realize opening and closing of gate, be pound with anti-the signal that car module sends control unit to by illuminant module, send signal to ULN2003A chip by control unit, come main story and the reversion of control step stepper motor.

Describedly anti-pound car module and comprise a pair correlation type photoelectric sensor, its photophore is separated with light receiving device, be separately positioned on the both sides, road surface at gate place, anti-car module of pounding is used to prevent car also not leave gate, gate just have dropped, the work by correlation type photoelectric sensor, send signal to control unit, signal is sent to the control module that pounds the door again by control unit, as shown in Figure 8, the optoelectronic switch that correlation type photoelectric sensor is made up of a photophore and a light receiving device, during use, photophore and light receiving device are contained in respectively and detect the both sides of thing by path, detect thing by time stop light path, light receiving device exports a switch controlling signal with regard to action, when there being signal, signal will be sent to chip LM339AJ and amplify by U6, signal is being sent to the port P33 of single-chip microcomputer.

Principle of the present invention:

Power module provides power supply to whole system, single-chip microcomputer be receive, the signal of illuminant module and Ground induction coil module carries out control display module and gate control module; When ground induction coil senses and sends a car signal, can signal be sent to single-chip microcomputer; If ground induction coil does not receive signal, illuminant module will produce effect, continues induced signal and sends the signal of acceptance to single-chip microcomputer; Display module is used to display welcome words or other information; Gate control module is the opening and closing of regulating gate, is when receiving gate opening signal, gate opening, when receiving closing gate signal, and closing gate; If have in the process of closing gate car not by or have personnel's process, prevent that pounding car module will produce effect, to single-chip microcomputer transmission signal, signal is sent to gate control module through process, so that stepper motor stops operating, pound car module until anti-and do not receive signal, gate continues to fall again, and motion flow as shown in Figure 9.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
