Description
Technical field
The present invention relates to the adapter technique field, refer in particular to a kind of being installed on the mainboards such as computing machine or digital TV set-top box and the suitable remote control adapter of telepilot.
Background technology
The electrical equipment that computing machine, digital TV set-top box etc. are remote-controlled is normally realized transmitting and receiving of remote signal by the adapter on telepilot and the electrical equipment mainboard.In existing remote control adapter, adapter is the signal of passive reception telepilot emission; Can't be initiatively, the control relevant devices transmits; And, need take a USB interface and serial ports simultaneously; Thereby, make that the adapter on active computer, televisor and the digital TV set-top box has defectives such as applicability is not strong, function singleness, power consumption height.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of signal that can not only receive the Infrared remote controller emission, and can launch the remote control adapter that corresponding infrared signal removes to control other equipment according to actual needs.
The technical matters that the present invention solves is achieved by the following technical solution: include receiving circuit and radiating circuit, receiving circuit mainly is made of the infrared ray receiving integrate circuit; Radiating circuit mainly is made of infrared-emitting diode, triode; Infrared-emitting diode connects the emitter of triode, and the collector of triode links to each other with the parallel circuit of resistance and polar capacitor, and the circuit that other has a polar capacitor and aforementioned infrared-emitting diode, triode, resistance and polar capacitor to constitute is in parallel; The base stage of infrared ray receiving integrate circuit, infrared-emitting diode and triode can be connected with the serial ports of circuit main board, is provided with a voltage changer between described infrared-emitting diode and serial port of mainboard.
Described voltage changer model is AMS1117-5.0.
The supply voltage of described receiving circuit and radiating circuit is 5V.
Described infrared ray receiving integrate circuit model is TSOP1738.
Described triode model is MMBT3904.
The present invention mainly is the setting of voltage changer and radiating circuit segment polarity electric capacity by the design to adapter circuit; Make the present invention only need take the interface of a serial ports, applicability strengthens greatly; Only need to use a serial ports, just can realize infrared reception and transmission.And in conjunction with the control of software; Make adaptive beneficial effect of the present invention with following several aspects:
1, can write down (study) N and prop up telepilot, promptly pass through to receive the signal of any each button of telepilot, and be converted into a series of numeral by software, and it is recorded in the corresponding configuration file according to the level variation of receiving circuit.
2, only need an interface, easy for installation, use simple.
3,5V supply voltage makes the low in energy consumption of adapter.
4, can in 5 meters scopes, realize infrared control to household appliances, promptly by reading corresponding configuration file, and then the corresponding a succession of numeral of the signal that reads certain button that writes down certain telepilot that obtains, and be translated into the level signal of variation, by activating radiating circuit, thereby launch remote signal to certain household appliances, thereby realize the function of this electrical equipment corresponding remote controller.
Thereby adapter of the present invention can be widely used in the reception based on the Infrared remote controller under the linux system, and launches corresponding infrared signal and go to control infrared remote control equipment on every side, as televisor, DVD, computer etc.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing:
Accompanying drawing 1 is a circuit structure block diagram of the present invention;
Accompanying drawing 2 is control flow block diagrams of the present invention.
Embodiment
See accompanying drawing, adapter of the present invention includes receiving circuit 1 and radiating circuit 2, and receiving circuit 1 mainly is made of infrared ray receiving integrate circuit U2.Radiating circuit 2 mainly constitutes the two-way circuit by infrared-emitting diode LED1, triode Q1, and one the tunnel is the emitter c that infrared-emitting diode LED1 connects triode Q1, and the current collection e of triode links to each other with the parallel circuit of a resistance R 2 and polar capacitor C3; Another road is a polar capacitor C2; Preceding two-way circuit is in parallel.The 5V power supply is given aforementioned receiving circuit 1 and radiating circuit 2 power supplies; And between the power supply of radiating circuit 2 and serial port of mainboard, be provided with a voltage changer U1 (being between infrared-emitting diode LED1 and the serial port of mainboard); Thereby making adapter of the present invention only need take a serial ports gets final product; And need not take a USB interface simultaneously.The voltage input pin of infrared ray receiving integrate circuit U2, voltage changer U1 and the base stage b of triode Q1 can be connected with the serial ports of circuit main board.Described voltage changer U1 model is AMS1117-5.0, and infrared ray receiving integrate circuit U2 model is TSOP1738, and triode Q1 model is MMBT3904; Certainly, the model of voltage changer U1 of the present invention, infrared ray receiving integrate circuit U2, triode Q1 is not limited to the above.
On the basis of aforementioned circuit of the present invention, being installed on set-top box, and being implemented in and showing on the televisor that fire alarm information is that example can use software to adopt following flow process control:
Mainly comprise following several steps:
After A, the start-up system, start remote control adapter; Carry out initialization by initialization module 01;
B, carry out first step activation signal and detect;
If detect, then enter startup sending module 02 step;
Otherwise, then enter startup receiver module 03 step;
Behind C, the startup receiver module 03, carry out the second step activation signal and detect;
If then enter startup sending module 02 step;
Otherwise, carry out remote signal and detect;
If D detects remote signal, then start remote control module 04, carry out the second step activation signal then and detect; Carry out subsequent step according to detection case again;
If the remote signal of not detecting then continues the 3rd step activation signal and detects;
E, carry out after the 3rd step, activation signal detected,
If detect activation signal, then enter startup sending module 02 step;
If do not detect activation signal, then proceed the second step activation signal and detect;
F, startup sending module 02 step are to send fire alarm information to equipment, and system closes after showing fire alarm information; After this, can enter initialization module 01 once more.
