(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.As shown in Figures 1 to 8, this kind is based on the automatic door of PLC control system, comprise the executing agency of power supply, doorframe 2, the door leaf 3 opened respectively to both sides, master controller and drive door leaf 3 switch, the inner side and outer side above doorframe 2 is installation infrared sensor K1 respectively, and executing agency comprises, door leaf orbit 5 above doorframe 2, door leaf 3 upper end is provided with door leaf suspender and walks wheel system 6, and motor 8 and door leaf suspender are walked between wheel system 6 and linked by synchronous belt 7 or Belt Drive, doorframe 2 be provided with enabling door magnetic and close every magnetic, doorframe 2 is also provided with and controls the operation initial point of door leaf 3 and the door open limit electric switch K3 of terminal and close door limiting electric switch K4, guidance system 4 is also provided with below doorframe 2, (take upper part as prior art, so only substantially illustrate in FIG, do not draw concrete structure, door leaf orbit 5 and door leaf suspender are walked wheel system 6 and are all installed together with doorframe, so cannot see, also only illustrate at doorframe place) master controller employing PLC 9, PLC 9 connects infrared sensor K1 respectively, K2, motor 8, door open limit electric switch K3, close door limiting electric switch K4, enabling door magnetic and close every magnetic, PLC 9 is provided with editable man-machine interface, as shown in Figure 2, PLC 9 comprises chip, I0.0 leg on described chip connects startup shutdown switch KB, I0.1 leg is connected infrared sensor K1 and K2 respectively with I0.2 leg, I0.3 leg connects door open limit electric switch K3, I0.4 leg connects pass door limiting electric switch K4, I0.5 leg connects the K switch 5 that opens Door by Hand, I0.6 leg connects manual door closing switch K6, I0.7 leg connects overcurrent protection circuit KA, Q0.1 leg connects enabling time-delay relay T37, Q0.2 leg connects the time-delay relay T38 that closes the door.Wherein:
PLC 9 is command centres of whole automatic door, is composed of the large-scale integrated block of instruction repertorie, sends command adapted thereto by inside, and this whole system works, and regulates the parameter such as door leaf 3 opening speed and unlatching amplitude by PLC control system simultaneously;
Infrared sensor K1 is responsible for gathering external signal, and as the eyes of people, when there being the object of movement to enter its working range, it just gives PLC 9 one pulse signals;
Motor 8 provides the active force of opening the door with closing the door, and controls door leaf 3 and accelerates and run slowly.
Door leaf 3 row fortune track: just as the rail of train, wheel system walked by the door leaf suspender of constraint door leaf 3, makes it be undertaken by specific direction.
Wheel system 6 walked by door leaf suspender: for hanging swing leaf 3, drives door leaf 3 to run under power traction simultaneously.
Synchronous belt 7 or V belt: for transmit motor 8 produce power, wheel system 6 walked by traction door leaf suspender.
Guidance system 4: the guiding and the positioner that are door leaf 3 bottom, front/rear door body swings to prevent door leaf 3 from operationally occurring.
Due to automatic door longevity of service, security requirement is high, and therefore, as shown in Figure 4, power acquisition protection circuit, protection circuit comprises transformer, overvoltage crowbar, interchange electromagnetic interface filter, rectification circuit, overcurrent and overheating protection circuit, secondary filter.
Workflow is as follows: when infrared sensor K1 senses that someone enters, pulse signal is passed to PLC 9, and PLC 9 judges rear notice motor 8, monitors motor 8 revolution simultaneously, to notify that motor 8 is afterburning and enter operation of going slowly certain time.Motor 8 is made forward and is run after obtaining certain running current, power is passed to synchronous belt 7, then by Timing Belt, power is passed to sling system automatic induction door door leaf 3 is opened; Automatic induction door door leaf 3 is judged by PLC after opening, if need close automatic induction door, notice motor 8 does reverse motions, closes automatic induction door.
As shown in Figure 5, in conjunction with workflow block diagram illustratively workflow again:
(1) when have people have in during outward or from outside to inside by infrared sensor K1 or K2, enabling time-delay relay T37 action, motor rotates forward, and when arriving door open limit electric switch K3 position, motor is out of service.
(2) door leaf is after opening position stops 8s, and automatically enter door closing procedure, the time-delay relay T38 that closes the door is activated, motor reversal, and when door leaf moves to door limiting electric switch K4 position, pass, motor is out of service.
(3) in door closing procedure, when there being personnel from outside to inside or from inside to outside by infrared sensor K2 or K1, should stopping immediately closing the door, and automatically enter open door procedure.
(4) in the 8s stand-by period after door leaf is opened, if when having personnel from outside to inside or from the inside to the outside by infrared sensor K2 or K1, after must restarting to wait for 8s, more automatically door closing procedure is entered, to ensure personnel's safety.
Except technical characteristic described in manual, all the other technical characteristics are those skilled in the art's known technology.
