Inside one classroom, open a window holding ventilation always, and at this time wind can blow projection screen, and drop shadow effect is affected, and influence
Teaching.
Utility model content
The utility model is intended to provide a kind of curtain system based on controlled in wireless that projection screen position can be kept stable
System.
The curtain system based on controlled in wireless in this programme, including,
The RF transmitter of mobile terminal is arranged on, for launching the control information on the mobile terminal；
The infrared receiver being arranged on curtain, for receiving the control information of the RF transmitter transmitting；
The electromagnet of curtain bottom is arranged on, for holding the iron plate being arranged on wall；
Power module, for being powered to the electromagnet；
The relay of curtain bottom is arranged on, for opening and closing the power module；
Microcontroller, for receiving the control information of the infrared receiver transmission and controlling opening for the relay
Close.
The principle of this programme is：
User needs to download the application software of remote control on mobile terminals in advance.When user has found that curtain starts to put
When dynamic, drop shadow effect is affected, RF transmitter emission control information of the user by installation on mobile terminals, if
The control information that the infrared receiver on curtain receives RF transmitter transmitting is put, the control information is sent to micro-
Controller, microcontroller starting relay, at this moment, power module are powered to electromagnet, and electromagnet attracts in the state of having electricity
The iron plate being arranged on wall, electromagnet are bonded on iron plate.
The beneficial effect of this programme is：
Compared with prior art, this programme uses the keying of infrared and radio control relay, and startup power supply module is to electricity
Magnet is powered, and full of magnetic, the iron plate being arranged on wall attracts, plays a part of firm curtain bottom, prevent curtain
Blown by wind bottom so that drop shadow effect is not affected by wind.
Further, in addition to motor and rotating shaft, the rotating shaft and the motor connection, the curtain are wound on the rotating shaft bar
On.When user needs to use curtain, manual control electric motor starting, the rotational band turn axostylus axostyle of motor rotates, meanwhile, rotating shaft
Curtain on bar is slowly put down, and when falling on certain position, closes motor；When user does not need curtain, artificially open again
Dynamic motor, motor driven rotating shaft bar rotates backward, and during rotation, rotating shaft bar packs up curtain slowly, easy to operate.
Further, in addition to Access Division, the Access Division is arranged on the bottom of the curtain, the relay with it is described
Infrared receiver is arranged in the Access Division.Relay and infrared receiver are arranged on Access Division, be in order to
Increase weight to curtain, under the influence of gravity, curtain can be fallen vertically downward, keep the vertical plane of curtain.
Further, the electromagnet is at least arranged to 4, and is distributed on the Access Division arranged on both sides.Set in Access Division
It is for more firm curtain to put 4 Access Divisions, prevents curtain from being blown by wind.
Brief description of the drawings
Fig. 1 is the structural representation of curtain system embodiment of the utility model based on controlled in wireless；
Fig. 2 is the frame diagram of curtain system embodiment of Fig. 1 the utility model based on controlled in wireless；
Fig. 3 is the circuit diagram of curtain system of Fig. 1 the utility model based on controlled in wireless.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：Rotating shaft bar 1, curtain 2, electromagnet 3, relay 4, infrared receiver
5th, iron plate 6, RF transmitter 7.
Embodiment is substantially as shown in Figure 1：The system of curtain 2 based on controlled in wireless, including rotating shaft bar 1, pacify on rotating shaft bar 1
Equipped with curtain 2, for curtain 2 in the state of, curtain 2 is volume on rotating shaft bar 1；The above-mentioned side of rotating shaft bar 1, which is provided with, to be used
In the motor for starting the rotating shaft bar 1 rotation, when curtain 2 needs to use, artificially start motor, motor driven rotating shaft bar 1
Rotate, and the curtain 2 rolled up on rotating shaft bar 1 is fallen slowly, because the bottom of curtain 2 is provided with the clamping with constant weight
Portion, curtain 2 are influenceed by Access Division gravity, and curtain 2 is fallen vertically downward, and relay 4 is provided with Access Division, relay 4
Side is provided with infrared receiver 5, as shown in Fig. 2 the infrared receiver 5 is used to receive installation on mobile terminals infrared
The information that line transmitter 7 is launched, is provided with 4-10 electromagnet 3 on Access Division, and is distributed on the both sides of Access Division, electromagnet 3
For holding the iron plate 6 being arranged on wall.
User needs to download remote control applications software on mobile terminals in advance, when user has found that curtain 2 starts to put
When dynamic, drop shadow effect is affected, and user can be believed by the emission control of RF transmitter 7 installed on mobile terminals
Breath, the information of the receiving infrared-ray transmitter 7 of infrared receiver 5 transmitting on curtain 2, due to infrared receiver 5
Microcontroller is electrically connected, therefore, the control information received is passed to microcontroller by infrared receiver 5, as shown in figure 3,
Because microcontroller is electrically connected contact relay 4, two inputs of relay 4 respectively with microcontroller and be connected, the relay 4
