Description
Technical field
The utility model relates to household appliance remote control debugging technique, is specially a kind of custom coding remote-controlled launcher.
Background technology
At present, household appliance remote control system major part all adopts infrared remote control mode, such as televisor, air-conditioning etc., because using the household electrical appliances of infrared remote control more, may be there is the problem that the remote control of different product is disturbed mutually in use in user, as TV remote controller interference DVD remote control etc.For this reason, portions of client is when product customization, require the problem using special remote control coding modes to avoid remote signal mutually to disturb, the coded system of different customer requirements is inconsistent, cause factory when scheduling and planning, the frock telepilot of a large amount of different coding need be configured, cause the increase of frock telepilot management difficulty and manufacturing cost.
Summary of the invention
In order to solve above technical matters, the utility model provides a kind of custom coding remote-controlled launcher, and it can carry out flexible configuration, thus meets the remote control debugging needs of different remote control product, greatly reduces manufacturing cost and debugging difficulty.
The technical scheme that the utility model adopts for technical solution problem is:
A kind of custom coding remote-controlled launcher, comprising: STM32 microcontroller, is provided with the first output terminal exporting 38KHz pwm signal based on its timer internal, and is provided with the second output terminal for exporting NEC infrared coding clock signal; Modulating unit, receives the 38KHz pwm signal of the first output terminal and the NEC infrared coding clock signal of the second output terminal, exports infrared encoded signal; Transmitter unit, receives the infrared encoded signal of modulating unit and outwards launches; Setting unit, its output terminal is connected with STM32 microcontroller, for arranging the NEC infrared coding clock signal that STM32 microcontroller exports.
As preferred embodiment, described setting unit is the combination of TFT display screen and touch-screen.
The beneficial effects of the utility model are: the utility model utilizes pwm signal to produce required infrared encoded signal with the mode of the infrared coding clock signal combination that can arrange, and principle is simply ingenious; Only infrared coding clock signal need be changed by setting unit during use, just required infrared coding can be obtained, thus meet the remote control debugging needs of different product, factory is when producing the product of special remote control coding modes, do not need to make special frock telepilot again, decrease the input of frock telepilot, reduce manufacturing cost, factory is when production product forwards the product of another different remote control coding modes to, do not need to change the frock telepilot of each station, directly arrange according to the remote control coding of client definition.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the block diagram of system of the present utility model;
Fig. 2 is the circuit theory diagrams of modulating unit and transmitter unit.
Symbol description: 1-SMT microcontroller, 2-modulating unit, 3-transmitter unit, 4-setting unit.
Embodiment
Remote-controlled launcher of the present utility model is mainly used in debugging various infrared remote control product, and the infrared coding of this emitter can be arranged, and can meet the debugging needs of various different product.
With reference to Fig. 1, remote-controlled launcher of the present utility model forms primarily of SMT32 microcontroller 1, modulating unit 2, transmitter unit 3 and setting unit 4.Setting unit 4 output terminal is connected with STM32 microcontroller 1, for arranging the NEC infrared coding clock signal that STM32 microcontroller exports, setting unit 4 preferably utilizes TFT display screen and touch screen combination to form, what user can know device easily arranges state, and by the parameters of the mode modifier of touch, thus the infrared encoded signal needed for device output can be made.
SMT32 microcontroller 1 requires the Embedded Application custom-designed ARM Cortex-M3 kernel of high-performance, low cost, low-power consumption based on aiming at.Microcontroller 1 is provided with and exports the first output terminal of 38KHz pwm signal and the second output terminal for exporting NEC infrared coding clock signal based on its timer internal.
Modulating unit 2, for the NEC infrared coding clock signal of the 38KHz pwm signal and the second output terminal that receive the first output terminal, exports infrared encoded signal; Transmitter unit 3 is for receiving the infrared encoded signal of modulating unit and outwards launching.
The circuit theory diagrams that Fig. 2 adopts for modulating unit 2 and transmitter unit 3.Figure comprise a NPN type triode and and many branch roads received on its collector, the grounded emitter of NPN type triode, 38KHz pwm signal is input in the base stage of NPN type triode.Every bar props up route one PNP type triode and infrared LEDs composes in series, NEC infrared coding clock signal IR is input in the base stage of PNP triode, the emitter of PNP triode is connected with power supply VCC, and collector is connected on the collector of NPN triode through infrared LEDs.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
