Described door device for identifying opening 12 comprises: a microcontroller, a randomizer, a signal projector, a signal receiver, a relay and a warning device.Described randomizer, signal projector, signal receiver, relay and warning device are all connected with this microcontroller.
Described microcontroller has analog/digital conversion interface, with connection signal receiver, thus can judge the light intensity received and frequency change.After described microcontroller is encoded according to the random number that randomizer produces, thus control the signal of this signal projector transmission containing random coded, as infrared ray; And described microcontroller receives the random coded of this signal receiver reception simultaneously, and the light intensity received and frequency change are judged.Described microcontroller is shown and signal output judged result by warning device and relay.
Described randomizer comprises a random number generation circuit.This random number generation circuit be designed with two schemes.One adopts existing special random number to produce integrated circuit (IC) chip.Another kind is that utilize microcontroller timer to produce random data to the method that this time carries out timing, this is also general conventional design, repeats no more here according to the capacitance-resistance discharge and recharge time in the very coarse characteristic of musec order.
The signal transmissions such as infrared ray, bluetooth, Wifi or RFID can be passed through between described signal projector and signal receiver.Described warning device is one or more in pilot lamp, Vib. and acoustical generator.In the present embodiment, described signal projector and signal receiver are an infrared transmitter and infrared receiver; Described warning device is a red green pilot lamp.Be appreciated that described relay and warning device are alternate configurations.Described signal projector, signal receiver, relay and pilot lamp are all general conventional design and use, repeat no more here.
Be appreciated that the microcontroller of described door device for identifying opening 12 can directly be electrically connected with master controller, also can be electrically connected with master controller by this relay.The complete compatible conventional door magnetic signal of output of described relay exports, and can, by master controller identification, be easy to connect existing various Gate-ban Monitoring System.In the present embodiment, the microcontroller of described door device for identifying opening 12 is electrically connected with master controller by this relay.
As shown in Figure 2, the gate control system 10 of the utility model embodiment can also comprise the supporting door leaf 22 of a doorframe 20 and one and this doorframe 20 further.Door shown in Fig. 2 is the door that control people passes through.The body 120 of described door device for identifying opening 12 is installed on doorframe 20, and the signal receiver 122 of described door device for identifying opening 12 is installed on door leaf 22.Described body 120 is electrically connected with master controller by relay.Described body 120 comprises microcontroller, randomizer, relay and signal projector.Described microcontroller, randomizer, relay and signal projector are integrated in and form this body 120 together.Described signal receiver 122 is connected to the analog/digital conversion interface of the microcontroller of this body 120 by a data line 124.Be appreciated that described warning device can be integrated with on this body 120, also can be wired to the position being convenient to observe.
