Technical Field
The invention belongs to the field of intelligent building engineering, and relates to a circuit for realizing calling a same-floor elevator and turning on an elevator hall lighting lamp while a building owner swipes a card to open a door at a first-floor entrance machine of a building, so that the elevator waiting time is reduced and the lamp is turned on in advance, in particular to a circuit for calling the elevator and turning on the lighting in linkage by swiping the card to open the door at the entrance machine and a realization method thereof.
Background
Along with the improvement of the living standard of people in cities and the acceleration of the life rhythm, the requirements on the life are not only satisfied on materials, but also comfortable and convenient for humanized experience. In order to better embody the humanized design, the visual intercom system is improved in a plurality of high-end buildings, and the calling function of the doorway machine is increased. The elevator calling function is added to the elevator hall door machine on the first floor of the residence and each floor of the basement, namely, the owner enters the door and swipes the card to open the door on the door machine, and gives a signal to the elevator calling button all the way, so that the elevator calling is realized in advance, the time is saved for the owner, the elevator is effectively used to the greatest extent, and the energy utilization rate is improved. However, the elevator called by the doorway machine at present usually transmits an electric signal to an elevator machine room, the elevator called by the doorway machine is on the first floor, but the elevator machine room is on the top floor, so that the scheme is long in wiring, complex in construction, and prone to signal attenuation, and later maintenance is not facilitated. In the prior art, there is also a circuit based on a swipe card machine door opening linkage elevator and an implementation method thereof with application number 201610003479.3, which is recorded as follows: a circuit after the output of the entrance/exit doorway machine is reconstructed, and a PNP type triode Q, a resistor R and a normally open contact relay J are additionally arranged; the connection relation of the original door lock opening and closing branch is kept unchanged: namely, the DOOR + end of the output switch of the entrance/exit DOOR phone is connected with the anode of the direct current power supply, the DOOR-end of the output switch of the entrance/exit DOOR phone is connected with the anode of the DOOR lock after being connected with the DOOR opening button in series, and the cathode of the DOOR lock is connected with the cathode of the direct current power supply. The emitting electrode of the triode Q is connected with the DOOR + end of the output switch of the entrance/exit gate machine, the base electrode of the triode Q is connected with the DOOR-end of the output switch of the entrance/exit gate machine, the collecting electrode of the triode Q is connected with the coil of the relay J in series and then connected with the negative electrode of the direct-current power supply, the normally-open contact of the relay J is connected with the elevator call button on the same floor in parallel, and the base electrode of the triode Q is connected with the negative electrode of the direct-current power supply in series. From the realization: when the entrance/exit entrance machine is opened by swiping a card, the elevator is called at the same floor. The problems and the defects of long wiring, complex construction and signal attenuation of the original scheme are overcome. A design that seems perfect, but has fatal defects: when the entrance and exit doorway machine punches a card to open the door, the output switch of the entrance and exit doorway machine is disconnected, the triode Q is conducted and saturated, the relay J is attracted, and the normally open contact generates a connection signal to the elevator call button to call the elevator, so that the elevator call function is realized; however, at the moment, the base electrode of the triode Q is connected with the DOOR-end of the output switch of the entrance/exit DOOR phone, the base electrode current of the triode Q is not limited by the resistor R of which the base electrode is connected in series with the negative electrode of the direct-current power supply, but is controlled by the resistor R and the DOOR lock connected in series with the DOOR opening button in parallel, the base electrode current of the triode Q is controlled together, the resistance of the DOOR lock is far smaller than the resistor R, which is determined by the working characteristics of the DOOR lock, at the moment, due to the existence of the DOOR lock, the current flowing through the base electrode of the triode Q is far larger than the maximum current capable of being borne by the base electrode of the triode Q, the triode Q is damaged, and if the damage is the breakdown of the triode Q, at the moment, the DOOR lock cannot be opened by power failure. The circuit and the realization method based on the POS machine door-opening linkage elevator with application number 201610003479.3 are obtained by comprehensive analysis, and the conclusion is that the output switch of the entrance/exit door machine is disconnected:
when the base of the triode Q can bear the current required by the door lock, namely the triode Q can not be damaged:
firstly, saturating a triode Q: a coil of the relay J is electrified, a normally open contact of the relay J is switched on, and a trunk contact signal is output to an elevator call button to call the elevator, so that the elevator call function is realized;
the door opening button is pressed down, and the door lock is powered off to open the door;
the door lock can be opened without power loss because the door opening button is not pressed down;
fourthly, whether a door opening button is pressed down or not influences the saturation depth of the triode Q;
when the base of the triode Q can not bear the current required by the door lock, namely the triode Q is damaged:
if the base of the triode Q is blown (not considering whether the coil of the relay J is energized),
if the door opening button is pressed down, the door lock is powered off to open the door;
secondly, if the base of the triode Q is broken down (whether the coil of the relay J is electrified or not is not discussed),
firstly, a door opening button is pressed down, and a door lock is powered off to open the door;
and secondly, the door opening button is not pressed down, and the door lock cannot be opened without power loss.

When the illuminance of the use environment is sensed to be larger than the set threshold value, the switch cannot be turned on no matter how loud the loudness is sensed, namely, the lamp is turned off no matter how loud the loudness is sensed. Therefore, when the illumination of the elevator hall is insufficient, the 'people arrive at the lamp and turn on the lamp, and the people walk away from the lamp'.
It is well known that: a user can pay a certain distance to an elevator hall at the same floor by swiping a card to enter the elevator hall, and very loud sounds (such as footsteps or speaking sounds) can be intentionally generated after the user swipes the card to enter the elevator hall in order to conveniently walk to the elevator hall at night, so that the sound and light controlled delay switch of the elevator hall illuminating lamp senses the sound loudness larger than the sensitivity, and the elevator hall illuminating lamp is started as early as possible.

The condenser electret microphone consists of an acoustic-electric conversion system and a field effect tube, wherein the condenser electret microphones of two lead-out wires are respectively a drain electrode of the field effect tube and a source electrode of the field effect tube; the drain electrodes of field effect tubes in the capacitor type electret microphones of the two lead-out wires are not only the positive power input end but also the signal output end, and the source electrodes of the field effect tubes are connected with the negative electrode of the power supply; and a pin marked as '+' in the condenser electret microphone of the two output lines is a field effect tube drain, and the other output line is a field effect tube source and is connected with the microphone shell. The pin of the capacitor electret microphone with the two output lines is marked as "+", which is generally called as the anode of the capacitor electret microphone, and the other output line is generally called as the cathode of the capacitor electret microphone. The sound detection circuit of the sound and light control delay switch adopts two capacitor electret microphones which lead out wires: the anode is connected with a high potential end (a power supply anode) through a resistor, and is used as a signal output through a capacitor and led to the input end of the amplifying circuit, and the cathode is connected with the power supply cathode.

The door opening button is a normally closed button and is a door opening button of the door lock and used for operation when the door is opened, when the door opening button is pressed down, the door opening button is disconnected from a normally closed state, the door opening button is released, and the switch of the door opening button is switched on and is restored to be normally closed.
The door lock is characterized in that: the door is locked when in the power-on state; and when the door is in a power-off state, the door is opened. Under the normal door closing state: the output switch of the entrance/exit doorway machine 3050 is switched on, the switch of the door opening button is switched on, and the door lock is locked in an electrified state.
The diodes D10, D11 and D12 are switching diodes, and in order to ensure that the switching tube Q10 is reliably turned off when the output switch of the doorway machine 3050 is turned on, it is preferable that the diodes D11 and D12 are silicon switching diodes and the diode D10 is a germanium switching diode; the invention only selects two stages of diodes D11 and D12 from the low potential end of a switch tube Q10 to be connected in series in the forward direction in sequence and then connected to the negative electrode of a direct current power supply DC12V, and is used for selecting the resistance value of an upper bias resistor R10 of the switch tube Q10 which is large enough, so that the switch tube Q10 is ensured to be conducted and saturated when an output switch of an entrance machine 3050 is switched off, and the current flowing through the diode D10 is small when the output switch of the entrance machine 3050 is switched on, thereby saving electricity.
The switch tube Q10 is an N-channel enhancement type MOS tube which is a voltage driving element, and the grid (G) of the N-channel enhancement type MOS tube is a switch tube Q1The control end of 0, the drain electrode (D) of the N-channel enhancement type MOS tube is the high potential end of the switch tube Q10, and the source electrode (S) of the N-channel enhancement type MOS tube is the low potential end of the switch tube Q10. When the gate-source voltage u of the switching tube Q10GS≥UGS(th)When the voltage is started, the switching tube Q10 enters conduction saturation, namely the switching tube Q10 is switched on; when the gate-source voltage u of the switching tube Q10GS<UGS(th)When the voltage is turned on, the switch tube Q10 is turned off, i.e., the switch tube Q10 is turned off.
The resistor R11 is a bias resistor between gate and source electrodes of the switching tube Q10, is used for quickly releasing capacitance charges between the gate and source electrodes when the switching tube Q10 is cut off, and is used for ensuring that the clamping voltage on the diode D10 is reduced to the diodes D11 and D12 when the output switch of the entrance/exit doorway machine 3050 is switched on, so that the switching tube Q10 is reliably cut off; the switch is also used for leading the direct current power supply to the grid source electrode of the switching tube Q10 together with the upper bias resistor R10 when the output switch of the doorway machine 3050 is disconnected, so as to ensure the grid source voltage u of the switching tube Q10GS≥UGS(th)The voltage is turned on to make the switch tube Q10 conduct and saturate, and the switch tube Q10 is not damaged due to too high voltage.
The diode D10: firstly, when the output switch of the entrance/exit gate machine 3050 is disconnected, the door lock branch 100 is not affected by the power on of the linkage signal acquisition branch 200, namely, the door lock is ensured to be reliably opened when the output switch of the entrance/exit gate machine 3050 is disconnected, the control end voltage of the switching tube Q10 is effectively protected from being damaged due to overhigh voltage, and the function of protecting the switching tube Q10 is achieved, so that when the output switch of the entrance/exit gate machine 3050 is disconnected, the diode D10 is used for electrically isolating the door lock branch 100 from the linkage signal acquisition branch 200; and secondly, when the output switch of the entrance/exit door phone 3050 is switched on, the door lock branch 100 is electrically communicated with the linkage signal acquisition branch 200, and the output switch of the entrance/exit door phone 3050 is switched on, so that the switching tube Q10 is switched off from saturation.
