New house installed aluminum alloy and moved the door, had an opportunity to design an automatically-controlled door for oneself finally. The human body measures the emitting-receiving technology of adopting the report controller of the household electrical appliance partly, free of ambient light.
Fig. 1 is infrared receiving and electrical machinery driving circuit, the infrared receiver is received normally to come from the infrared beam sent over in the other side in nobody. Just insert the buffle tube Fig. 3 of the infrared transmitting tube long with 60 m m Fix on the wall parallelly, highly appropriate, and and the opposite receiver is aimed at, the infrared rays emitted like this is the budget, difficult to interfere with another receiver. The concrete method of erection is shown in Fig. 4 and shown. Export the low level after B G 6, B G 7, C R,etc. enlarge and filter, B G 5 ends at this moment, B G 2, B G 3 turns on the movements of carrying out and closing the door. When people go to the gate, the infrared light is blocked, B G 7 outputs the high level and drives B G 1, B G 4 to carry out the movements of opening the door through a route of limit switches, another No. is driven B G 5 to make B G 2 shut off by R 1, the switch off of door open limit when Moschus reaches the designated position, make the electrical machinery not resume and operate. When people leave, B G 7 no longer exports the high level, carries out the movements of closing the door after the electric capacity C 1 delay time for three seconds.
The transmitting circuit can reform system with the television report controller finished product ‘ Fig. 2 ,Connect original tube unloading on the specialized projector that is already done well with the lead wire, two projectors connect in parallel and pay attention to polarity. Then look for one appropriate key set short out it, let it launch, ” reject apparent ” preferably Key, in order to may try hard non-interference television in the radiation zone. The transmitted power is adjusted with R W, had better can just receive.
The major component is chosen: Four power tubes that the driving circuit of the electrical machinery uses are I R F 9 5 4 0 / P Type /100 V / 19 A and I R F 540 / field effect tube, N-type / 100 V / 28 A,because be driven of voltage it, be lasted propulsion power hardly. Internal resistance of it light, temperature rise very light, can mount together at the very much little aluminium sheet them, and it is insulating to pay attention to. The electrical machinery can reach the automobile parts shop to buy the rain-blowed device electrical machinery of 12 V, its arm of force of unloading, the gear that is installed a four-cycle motorcycle engine, connect with several small link chains, then make a support to fix on door with a steel plate, the concrete method of erection is shown in Fig. 5.
In order to prevent the normal use of the opposite house of the black out from causing influence, so I have designed stepping down and matching the storage battery of 12 V with the voltage transformer, the main circuit supplies power with 12 V, isolates from city power, the safety has been improved.
The automatic circuit diagram of automatic door:
It is an automatic gate control schematic circuit diagram to make the picture. The human body moves and surveys and adopts the infrared acquisition module HN911 of new pyroelectric. V1 is used as delaying time to control, can change the time to delay time and control through regulating the potentiometer RP1. The photosensitive resister MOC3020 plays a isolating in alternating and direct current role. When nobody walks to need to pass the automatically-controlled door, HN911 Ausgang is the low level, V1 uncontrolled image output, the bidirectional thyristor V2 is closed, supports the out-of-operation of the electrical machinery, the door is in closing state. When someone is close to the automatically-controlled door, HN911 module test infrared energy of the human body, the Ausgang I is exported for the high level, the bidirectional thyristor is turned on, support the electrical machinery and work, open the automatically-controlled door. When running in place in the automatically-controlled door, by the limit switch S power cut. The intersection of HN911 and just contrary to level of the Ausgang 1 level that module Ausgang 2 outputs, so can close with the output control automatically-controlled door in the Ausgang 2.
