Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.
With reference to Fig. 1-3, multi-media classroom is controlled energy supply control module, including main power control module, described main power control
Molding block is used for controlling sound view screen device energy supply control module and curtain energy supply control module, it is achieved sound view screen device power supply controls
The Guan Bi of module and curtain energy supply control module with open, described sound view screen device energy supply control module be used for controlling desktop computer,
Notebook, audio frequency play and projector, it is achieved desktop computer, notebook, audio frequency play and projector Guan Bi with open, described curtain
Cloth energy supply control module is used for controlling curtain, it is achieved the pull-up of curtain or closedown, described sound view screen device energy supply control module
Inside being provided with key point and key, described key point and crucial side and be provided with rest-set flip-flop, described rest-set flip-flop is various for constituting other
The element of function trigger, described rest-set flip-flop is possible not only to binary signal carries out arithmetical operation and logic fortune
Calculating, and can these signals and operation result be saved, can also prevent the shake of button simultaneously, described RS triggers
Device is provided with NPN audion away from key point and crucial side, described NPN audion be arranged over relay, described relay
The power supply of the equipment such as normal work, is also turned on desk computer by absorption switch, audio frequency power amplifier, scialyscope makes its normal work
Making, connect resistance R1 at the emitter stage of described NPN audion, the effect of described resistance R1 is to make relay and NPN tri-pole
Dividing potential drop when pipe is in the supply of Vcc bigger voltage, thus ensure that relay is in rated current duty, described NPN tri-pole
The side of pipe is provided with diode, described diode and relay and forms loop, it is ensured that equipment normally works, described curtain power supply control
Being provided with motor in molding block, during described motor forward voltage, the motor of curtain rotates forward, and drives curtain to realize simultaneously
The state " risen ", on the contrary, when being supplied to motor backward voltage, motor rotates backward, and the motor of curtain is reverse simultaneously
Rotating, drive curtain to realize the state of " fall " simultaneously, the realization of " stopping " state then has only to cut off external power source and motor
Path i.e. it is achieved that described sound view screen device power supply is electrically connected with desktop computer, notebook, audio frequency are play and projector, institute
It is provided with undervoltage protection device in stating main power control module, and undervoltage protection device is electrically connected with controller, described key point and pass
Key is electrically connected with rest-set flip-flop, and described rest-set flip-flop is electrically connected with NPN audion, and described NPN audion is electrically connected with relay
With resistance R1, described main power control module is electrically connected with sound view screen device energy supply control module and curtain energy supply control module.
Teaching equipment is to be opened by two ways: one is by panel button, and another is by IC-card Card Reader
Device manages the electrical condition of all teaching equipments, thus realizes instructor's simple operation to equipment, sound view screen device electricity
Input signal is reduced to two buttons of Push And Release by source control module, when carrying out "ON" operation, first passes through one substantially
Rest-set flip-flop, the effect arranging this trigger is: allow it be possible not only to binary signal to carry out arithmetical operation and logic fortune
Calculate, and these signals and operation result can be saved, the shake of button can also be prevented simultaneously.Now, K end will
