[embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model.
According to the principle of infrared remote controller, width modulation is adopted in remote control mode " 0 " and " 1 ", and pulsewidth has certain error, error is thought about 10% normally usually, exceeds this error and thinks mistake, can judge that telepilot has fault.Because the chip of telepilot is a lot, coded format is also different, and prefabricated multiple form type code selects to realize testing certain telepilot by mode of operation in giving testing apparatus.
Seeing also Fig. 1, is the block diagram of a kind of Infrared remote controller ability meter of the utility model.Described Infrared remote controller ability meter comprises infrared signal processing section 10 and microprocessing systems part 20.Described infrared signal processing section 10 comprises infrared receiver 11 and signal processing unit 12.Described microprocessing systems part 20 comprises Single Chip Microcomputer (SCM) system 21, display unit 22 and keyboard unit 23.Described infrared receiver 11 is connected with described signal processing unit 12.Described signal processing unit 12 is connected with described Single Chip Microcomputer (SCM) system 21, and described display unit 22 and keyboard unit 23 are connected respectively to described Single Chip Microcomputer (SCM) system.
During the work of described Infrared remote controller ability meter, infrared receiver 11 and signal processing unit 12 constitute integrated infrared receiving terminal, receive from the infrared signal of telepilot and carry out signal Processing.
In the present embodiment, the integrated infrared receiving terminal that infrared receiver 11 and signal processing unit 12 constitute, it comprises infrared monitoring diode, amplifier, limiter, bandpass filter, demodulator circuit, integrating circuit and comparer.Described infrared detection diode, amplifier, limiter, bandpass filter, integrating circuit are connected successively with comparer.The infrared monitoring diode monitors the infrared signal from telepilot to be tested, then signal is delivered to amplifier and limiter, and limiter is controlled at certain level to the pulse amplitude, no matter and the distance of infrared transmitter and receiver is far and near.Infrared signal enters bandpass filter, and bandpass filter can enter comparer by demodulator circuit and integrating circuit by the negative carrier of 30khz to 60khz, and comparer is exported high-low level, restores the signal waveform of telepilot transmitting terminal.The high-low level and the transmitting terminal of comparer output are anti-phase, thereby improve the sensitivity that receives.
Single Chip Microcomputer (SCM) system 21 receives from the infrared signal after the processing of signal processing unit 12 and carries out decode key information, demonstrate the user code of button by the charactron of display unit 22, compare with the Standard User sign indicating number of design, if equate then sound a buzzer.Single Chip Microcomputer (SCM) system 21 is handled infrared signal generally two kinds of methods, and timer query method and external interrupt trigger, and the utility model adopts the external interrupt triggering mode.
Integrated infrared the demodulation module model that described infrared receiver 11 is selected for use is SFH506-38.This module adopts the black epoxy encapsulation, sensitivity is higher, reach 35 meters with the miniwatt infrared transmitting tube receiving range that transmits, its main electric parameters is as follows: supply voltage VCC is 5V, the reception peak wavelength is 0.95um, and receiving angle is ± 55 degree, accepts distance and can reach 35 meters for maximum, quiescent current 0.5mA, receive frequency are 38KHz.
Described Single Chip Microcomputer (SCM) system comprises that model is the single-chip microcomputer of AT89c51, and this single-chip microcomputer is low-voltage, high-performance CMOS eight bit microprocessors of a kind of band 4K byte flicker programmable and erasable ROM (read-only memory) (FPEROM-Falsh Programmable andErasable Read Only Memory).This device adopts ATMEL high density nonvolatile memory manufacturing technology to make, and is compatible mutually with the MCS-51 instruction set and the output pin of industrial standard.
See also Fig. 2, behind the utility model Infrared remote controller ability meter electrification reset, program start, Single Chip Microcomputer (SCM) system 21 initialization ports are provided with the timing of Single Chip Microcomputer (SCM) system then, and timer is used to receive the infrared signal from signal processing unit 12.Then set the mode of operation of Single Chip Microcomputer (SCM) system 21, because the multiple infrared remote coding mode of this Infrared remote controller ability meter energy measurement, so need before beginning to measure, to select the infrared remote coding mode measured; Open interruption, infrared remote control links to each other with the interruption pin of single-chip microcomputer after receiving a signal paraphase, when having key to press, the high level meeting output signal 0 after a remote control paraphase that comprises 0 and 1 coding, will cause singlechip interruption (in the present embodiment, Single Chip Microcomputer (SCM) system 21 is redefined for negative edge and produces interruption); Call the charactron display subroutine, on display unit 22, show the encoded radio that receives; The scan matrix keyboard is judged to have or not button to press, if no button is by the next display subroutine that then calls, if keyboard unit 23 has key by next processing button program; The button subroutine is used to change test parameter, sets mode of operation.
