Abstract
A kind of method for emitting coding infrared ray with PC machine of the present invention, this method utilizes keyboard, mainboard, USB interface, infrared transmitting tube, the power supply of PC machine, under software support, PC machine can be made to have the function of transmitting coding infrared ray, operating keyboard can remote controlled electronic device, to make infrared remote-control operation become easy and efficient, it can feel convenient.
Description
Technical field
The present invention relates to PC machine, more particularly to a kind of method for emitting coding infrared ray with PC machine.
Background technique
Currently, PC machine in the market does not emit the function of coding infrared ray, remote controlled electronic device, can feel not side sometimes
Just.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of method for emitting coding infrared ray with PC machine, this method benefit
It can solve PC machine under software support with the keyboard of PC machine, mainboard, USB interface, infrared transmitting tube, power supply and do not emit volume
The function of code infrared ray, remote controlled electronic device sometimes, the problem of being inconvenienced.
To achieve the above object, technical scheme is as follows:
A method of emitting coding infrared ray with PC machine, the PC machine includes keyboard, mainboard, USB interface, infrared emission
Pipe, power supply, mainboard are connect with power supply, keyboard, USB interface respectively, and the USB interface is also connect with infrared transmitting tube, and power supply is given
Keyboard, mainboard, USB interface, infrared transmitting tube power supply, wherein the following steps are included:
A, it initializes；
B, main program is run；
C, operation keyboard generates scan code, which is sent into the port 60H and causes int9 interruption, jumps to b when not having key
Step；
D, CPU executes the input of int9 interrupt processing keyboard, the scan code in the port 60H is read, if the scan code is not
The scan code of Esc key then jumps to g step；
E, transmitting coding infrared ray identification position negates；
F, it interrupts and returns；
If g, transmitting coding infrared ray identification position is not 0, j step is jumped to；
H, it interrupts and returns；
J, calling coding infrared ray transmitting driving subprogram corresponding with scan code in the port 60H；
K, the subprogram drives the infrared ray of infrared transmitting tube transmitting coding by USB interface；
M, it interrupts and returns.
Beneficial effects of the present invention:
A kind of method for emitting coding infrared ray with PC machine of the present invention, this method are connect using the keyboard, mainboard, USB of PC machine
Mouth, infrared transmitting tube, power supply can make PC machine have the function of transmitting coding infrared ray, operation keyboard can under software support
With remote controlled electronic device, so that infrared remote-control operation be made to become easy and efficient, it can feel convenient.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is a kind of method work flow diagram for emitting coding infrared ray with PC machine of the present invention.
Specific embodiment
Principle and structure in order to further illustrate the present invention carry out the preferred embodiment of the present invention now in conjunction with attached drawing detailed
Describe in detail bright, however the embodiment is only to provide explanation to be used with explanation, cannot be for limiting scope of patent protection of the invention.
A kind of method emitting coding infrared ray with PC machine as shown in Figure 1 and Figure 2, the PC machine includes keyboard 1, mainboard

Also it is connect with infrared transmitting tube 4, power supply 5 is powered to keyboard 1, mainboard 2, USB interface 3, infrared transmitting tube 4, the method, including
Following steps: a, initialization；
B, main program is run；
C, operation keyboard generates scan code, which is sent into the port 60H and causes int9 interruption, jumps to b when not having key
Step；
D, CPU executes the input of int9 interrupt processing keyboard, reads the scan code in the port 60H, which is not Esc key
Scan code, jump to g step；
E, transmitting coding infrared ray identification position negates；
F, it interrupts and returns；
G, transmitting coding infrared ray identification position is not 0, jumps to j step；
H, it interrupts and returns；
J, calling coding infrared ray transmitting driving subprogram corresponding with scan code in the port 60H；
K, the subprogram drives infrared transmitting tube by USB interface, emits the infrared ray of coding；
M, it interrupts and returns.
The specific embodiment advantages and beneficial effects are that the present invention is a kind of to emit the side for encoding infrared ray with PC machine
Method, this method can make PC machine under software support using keyboard, mainboard, USB interface, infrared transmitting tube, the power supply of PC machine
Have a function of transmitting coding infrared ray, operation keyboard can remote controlled electronic device, so that infrared remote-control operation be made to become easy
And it is efficient, it can feel convenient.
The specific embodiment of only invention described above, various illustrations do not constitute limit to the substantive content of invention
System, person of an ordinary skill in the technical field can repair the specific embodiment described in the past after having read specification
Change or deform, all shall be regarded as belonging to protection scope of the present invention.
