Description
Technical Field
The invention belongs to the field of intelligent building engineering, and particularly relates to a circuit and an implementation method for realizing calling an elevator and lighting while an owner swipes a card to open a door at a first floor entrance/exit of a building, so that the elevator waiting time is reduced and the lighting is started in advance.
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. 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:
⑴ the triode Q is saturated, the coil of the relay J is electrified, the normally open contact of the relay J is connected, and one path of dry contact signal is output to the elevator call button to call the elevator, thus realizing the elevator call function;
⑵ when the door opening button is pressed, the door lock is powered off to open the door;
⑶ the door opening button is not pressed down, the door lock will not open the door when power is lost;
⑷ the saturation depth of the triode Q is affected by the pressing of the door opening button;
when the base of the triode Q can not bear the current required by the door lock, namely the triode Q is damaged:
⑴ if the base of transistor Q is blown (not discussed if the coil of relay J is energized),
if the door opening button is pressed down, the door lock is powered off to open the door;
⑵ if the base of transistor Q is broken (not considering whether the coil of relay J is energized),
① when the door opening button is pressed, the door lock is powered off to open the door;
② the door-opening button is not pressed, the door lock will not lose power to open the door.
It is known that: the elevator imports and exports in order to ensure that certain luminance makes things convenient for pedestrian's export and walking, will eliminate the constant bright lamp again, and the switch of general elevator room (elevator car door gate, the region that people wait) light adopts acousto-optic control delay switch, through adopting opening of the dual control lamp of acousto-optic, its characteristics are: when the illuminance of the use environment is sensed to be lower than a set threshold (generally taking a value between 0.9 and 1.8 Lx), as long as a sound which is larger than a set sound (for reducing the mistaken lamp turning-on to save electricity better, and ensuring that the lamp can turn on within a certain range under the lamp (such as footstep sound, speaking sound and the like) is sensed, the general sensitivity is set to be larger than 25 dB), the frequency is 50Hz to 12.5KHz, the switch is automatically turned on (the lamp is on) and is automatically turned off after the set time (generally designed to be 20 to 50 seconds) is delayed, the switch is kept in a turned-off state without the sound (the sensed sound is smaller than the set sound), in the delay of the set time, if the sound which is larger than the set sound is sensed again, the delay is cancelled and the lamp is kept turned on, and the delay is restarted when the sound which is not sensed to be larger than the set sound is not sensed, the switch is repeatedly turned back and, the turned on lamp will automatically turn off. 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. When the illumination of the environment is not enough, the lamp is on when a person arrives (senses that footstep sound or speaking sound and the like are more than set sound), and the lamp is off when the person walks.
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 elevator hall illuminating lamp is characterized in that a large sound is intentionally emitted after the elevator hall illuminating lamp is brushed and clamped into a door, and the elevator hall illuminating lamp is started as early as possible: the card is convenient to swipe at night and walk after entering the door, but the interference is caused to the life of other residents, and especially the rest of other residents is easily influenced at night.
