Abstract
The utility model discloses a projecting screen intelligent control device of a household computer intelligent control system, comprising MCU and a wireless emitter connected with the MCU data transmitting end; the MCU data end is connected with the RS-232 interface or USB interface communicated with the computer. The wireless emitter is the 433MHz RF wireless transmitting device. The utility model solves the shortcomings that the projecting screen is not compatible to the household control system in the current technology. The utility model has a simple structure, convenient use; the utility model can achieve the compatible combination of the projecting system and the household intelligent control system, which brings significant convenience for projecting screen to the users.
Description
Technical field
The utility model discloses a kind of control device of projection screen, particularly a kind of projection screen intelligence controlling device by the control of computer family intelligent control system.
Background technology
Raising along with people's quality of life; the quantity of home-use household electrical appliance is also more and more; and household electrical appliance of the prior art can adopt telepilot to control usually; along with increasing of household electrical appliance quantity; the quantity of telepilot also and then increases; the user is also more and more inconvenient to the management of telepilot, so just the someone proposes the viewpoint of home intelligence control system, by the various household electrical appliance in the household PC centralized management family.Along with the family oriented day by day of projector and projection screen, the use of projector equipment in people's life increases day by day.Projection screen in projector equipment of the prior art, the especially projector equipment in use, all be by pushbutton switch or telepilot control projection screen up and down, can not with home intelligence control system compatibility, bring a lot of inconvenience to use.
Summary of the invention
At the above-mentioned projection screen of mentioning of the prior art can not with home intelligence control system compatibility, bring the shortcoming of a lot of inconvenience to use, the utility model provides a kind of new projection screen intelligence controlling device, on the data-interface of MCU (being microprocessor), be connected with the communication interface that can be connected communication with computer, realize communicating by letter of computer and projection screen control device by communication interface, further realize the compatibility of optical projection system and home intelligence control system.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of projection screen intelligence controlling device, comprise MCU and the wireless launcher that is connected with the MCU data sending terminal, and be connected with the communication interface that can be connected communication on the MCU data terminal with computer.
The technical scheme that its technical matters that solves the utility model adopts further comprises:
Described communication interface is a RS-232 interface.
Described communication interface is a USB interface.
Described wireless launcher is the RF radio transmitting device of 433MHz.
The beneficial effects of the utility model are: the utility model is simple in structure, and it is convenient to realize, can realize that by the utility model optical projection system combines with the compatibility of home intelligence control system, brings great convenience for the use of projection screen.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is the utility model circuit structure block diagram.
System principle circuit structure block diagram when Fig. 2 uses for the utility model.
Embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection domain.
Please referring to accompanying drawing, the utility model circuit structure mainly comprises MCU, communication interface, wireless launcher, be connected with communication interface on the data terminal of MCU, the communication interface that provides in the present embodiment is a RS-232 interface, it perhaps is USB interface, during concrete enforcement, the also available communication interface that other can be connected and communicate with computer, realize communicating by letter between the utility model and the household PC by communication interface, with compatibility that reaches optical projection system and home intelligence control system and the purpose that is subjected to its control.Be connected with wireless launcher on the data sending terminal of MCU, MCU sends control information to wireless launcher, sends to wireless receiver in the projection screen by wireless launcher, thereby realizes the control to projection screen.In the present embodiment, wireless launcher and wireless receiver all are the radio transmitting devices that adopt 433MHz commonly used in the prior art, can not change the inner structure of projection screen, can realize the compatibility of docking of optical projection system and home intelligence control system, realize simple, convenient.During concrete enforcement, wireless launcher and wireless receiver also can adopt other forms of radio transmitting device, as: infrared ray, bluetooth etc.
The utility model in use, communication interface is connected with the corresponding interface on the computer, send control signal by the home intelligence control system of installing on computers, be transferred to the utility model by communication interface, after the utility model receives the control signal that computer transmits, the analysis of decoding in MCU is sent wireless control signal by wireless launcher and is given wireless receiver in the projection screen, with the rise and fall of control projection screen.
The utility model can be widely used in the control field of various dynamoelectric projection screens of the prior art, realizes the compatibility of docking of projection screen system and home intelligence control system.
