Described storer is used for store movies content-data, player service data, and control and the status information play.
Described audio frequency power amplifier parts, the voice data that the data processor transmission is come carries out processing and amplifying and output, with the acoustics that realizes playing as movie theatre.
Described touch control board is the key component that realizes modular integrated type structure, comprises the liquid crystal control flow that is arranged on outside.Because d-cinema projectors has and can store the multi-section film, what how to show, when shows and shows thus can regulate and control by described touch control board.The motion picture projection personnel can operate the projection of controlling film at the information of liquid crystal control flow as required.
Touch control board is delivered to control information in the data processor, controls the projection of film.Simultaneously,, show, realize that the projection personnel are to the duty of d-cinema projectors and the real-time monitoring of motion picture projection state by the liquid crystal control flow by from data processor, reading the status information of motion picture projection.
As the d-cinema projectors of above-mentioned scheme content, both can realize modular integrated type structure, again can be by the effective raising of touch control board control performance to film projector in the projection process.
D-cinema projectors with above-mentioned technical characterictic has an integrated circuit, this circuit serves as the control core with the W77E58 chip mainly, by the keyboard input control information, and be connected with communication between outer PC and the projection arrangement with the realization of MAX232 chip, carry out the demonstration of control information with the LCD dot matrix display screen.
Described W77E58 chip is the CPU of a 8bit, its XTAL1, the external crystal oscillator of XTAL2 pin; The RST pin is the electrification reset end;
The data one-way transmission of P0.0 to P0.7 pin and LCD display, P1.0 and P1.1 pin are the control lines of LCD; P2.0 to P2.6 pin constitutes the push-button array of 5 * 2 keyboards;
RXD and TXD, P1.2 and P1.3 pin are realized transmitting and control with the data of MAX232 chip chamber;
The compatible RS232 standard of described MAX232 chip, this chip includes 2 drivers, 2 receivers, and provides TIA/EIA-232-F level by a voltage generator.
Content to sum up, the advantage of the one-piece type d-cinema projectors of described touch control type is:
1, realize a kind of modular integral structure design, thus in integral housing configuration projection and projection arrangement, realize the miniaturization Design of d-cinema projectors and be easy to carry, transport.
2, cancelled original external communication interface, data processing and output are integrated together, and the data of effectively having avoided occurring in this process are revealed or loss, help carrying out copyright protection.
3, can be highly suitable for the projection that film is carried out in community and rural area by management and the projection of control panel realization to film.
4, embodied more fully that the digital movie memory space is big, picture is stable and characteristics that can recording played information.
