Abstract
The invention discloses a Bluetooth-based multimedia remote controller which has the functions of page-up, page-down, full-screen, full-screen exit and laser pointer. The remote controller comprises two parts, namely a mobile terminal and a fixed terminal. Through the remote controller, the movement space for a teacher is larger, the worst defect of the multimedia classroom teaching that the teacher is only limited to the space behind a computer is overcome, and great convenience is brought to demonstration of multimedia files.
Description
Technical field:
The present invention is a kind of application of Bluetooth technology in multimedia
Background technology:
Multimedia equipment has been installed in the classroom of each colleges and universities at present, in each professional teaching, and particularly morphologic course.Such as pathology, human anatomy, a large amount of especially use multimedias are as the classroom instruction means.Application of multimedia is technological, can remedy a lot of deficiencies of traditional teaching mode.But the computer layout of most of multi-media classroom is positioned at the screen side; The teacher is seated or is standing and can not reach the effect of face-to-face exchange with the student; The situation that the result has caused the student that teacher " is only heard its sound, loses its people " is if the student is just in the face of projection screen; Certainly will lack the classroom atmosphere of hommization somewhat so, therefore need improve in this respect.When particularly this type of human anatomy often needed body language to carry out object teaching, it is more abundant that this drawback exposes, and this also is that part Faculty and Students are to feeling incomplete main cause in the multimedia teaching.
Summary of the invention:
The present invention is exactly to the problems referred to above, provides a kind of and is more conducive to and the exchanging of student, and the multimedia remote controller of student's feedback information is expressed and more come to multi-angle more clearly.
For realizing above purpose, the present invention adopts following technical scheme, the present invention includes portable terminal and fixed terminal two parts.
Portable terminal is made up of power supply modulator circuit, keyboard, laser transmission circuit, microcontroller, serial communication circuit, bluetooth serial ports adapter.Behind the mobile terminal device electrifying startup; Microcontroller and bluetooth equipment carry out initialization earlier, and in order further to reduce power consumption, single-chip microcomputer gets into idle battery saving mode then; When button is pressed; External interrupt 0 is interrupted to the microcontroller application, wakes single-chip microcomputer up, and gets into the service routine of external interrupt 0.In interrupt service routine, detecting is that key is pressed; When detection was pressed for S1, single-chip microcomputer sent page-turning instruction down through the bluetooth serial ports adapter to fixed terminal; When detection was pressed for S2, single-chip microcomputer sent to fixed terminal through the bluetooth serial ports adapter and goes up page-turning instruction; When detection was pressed for S3, single-chip microcomputer sent full frame instruction through the bluetooth serial ports adapter to fixed terminal; When detection was pressed for S4, single-chip microcomputer sent to fixed terminal through the bluetooth serial ports adapter and withdraws from full frame instruction.
Fixed terminal mainly is made up of host computer and bluetooth USB adapter, and the host computer application program of fixed terminal adopts VC to write, and bluetooth USB adapter is set to main equipment; After program brings into operation; At first initialization bluetooth USB adapter, enquiry mobile terminal then is after finding portable terminal; Agreement and password to provide in advance carry out authentication, when authentication through after fixed terminal and portable terminal set up the wireless connections circuit.Begin then to inquire about and the instruction that sends over of mobile terminal receive, and carry out 0 operation accordingly according to instruction, thus realize through portable terminal to the last page turning of presentation file, following page turning, full frame, withdraw from full frame operation.
Beneficial effect of the present invention:
The present invention has last page turning, and following page turning is full frame; Withdraw from functions such as full frame, laser pen, make teacher's activity space bigger; Solved the maximum drawback that in the past only is confined to this multimedia classroom instruction after the computer, for the demonstration of multimedia document provides great facility.

Embodiment
Behind the mobile terminal device electrifying startup; Microcontroller and bluetooth equipment carry out initialization earlier, and in order further to reduce power consumption, single-chip microcomputer gets into idle battery saving mode then; When button is pressed; External interrupt 0 is interrupted to the microcontroller application, wakes single-chip microcomputer up, and gets into the service routine of external interrupt 0.In interrupt service routine, detecting is that key is pressed; When detection was pressed for S1, single-chip microcomputer sent page-turning instruction down through the bluetooth serial ports adapter to fixed terminal; When detection was pressed for S2, single-chip microcomputer sent to fixed terminal through the bluetooth serial ports adapter and goes up page-turning instruction; When detection was pressed for S3, single-chip microcomputer sent full frame instruction through the bluetooth serial ports adapter to fixed terminal; When detection was pressed for S4, single-chip microcomputer sent to fixed terminal through the bluetooth serial ports adapter and withdraws from full frame instruction.
The host computer application program of fixed terminal adopts VC to write; Bluetooth USB adapter is set to main equipment, after program brings into operation, and at first initialization bluetooth USB adapter; Enquiry mobile terminal then; After finding portable terminal, carry out authentication with agreement and the password that provides in advance, when authentication through after fixed terminal and portable terminal set up the wireless connections circuit.Begin then to inquire about and the instruction that sends over of mobile terminal receive, and carry out 0 operation accordingly according to instruction, thus realize through portable terminal to the last page turning of presentation file, following page turning, full frame, withdraw from full frame operation.
