Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1 is theory diagram of the present invention;
Fig. 2 is workflow diagram of the present invention.
Embodiment
As shown in Figure 1, be a kind of laboratory of the present invention burn-in test alarm set, for monitored testing equipment 8(as television set, or other audio & video equipments) burn-in test;
Fault reminding unit 5, remote control command transmitter unit 6, instruction input unit 7, sound monitoring unit 2 and/or video bitmap monitoring unit 4 that this device comprises power subsystem 1 and is connected with MCU unit 3, power subsystem 1 is that MCU unit 3 and each unit of being connected with MCU unit 3 are powered, to provide each cell operation voltage, electric current;
Wherein, this instruction input unit 7 for input realize content measurement, test request instruction to MCU unit 3, content measurement includes but not limited to intensity of sound, test period, remote control code etc.; Instruction input unit 7 inputs clear and definite instruction with keyboard or membrane keyboard prosecutor formula to MCU unit;
Remote control command transmitter unit 6 is for controlling the operating state of monitored testing equipment 8, it carries out wireless instructions communication with infrared, WIFI, bluetooth or radio-frequency carrier mode to monitored testing equipment 8, and monitored testing equipment can be made to carry out work by the wireless instructions exported;
This sound monitoring unit 2 is for gathering the voice signal in residing space when monitored testing equipment 8 works, and gathered voice signal is compared with set point, such as when higher or lower than the threshold level limited, then MCU unit 3 is fed back to the testing result exceeding set point; Here sound monitoring unit 2 mainly refers to pick-up/microphone.
This video bitmap monitoring unit 4 has image photographic and shoot function, for gathering and storing picture signal when monitored testing equipment 8 works, this video bitmap monitoring unit 4 by the front and back picture signal that gathers and store carry out identifying, comparing difference degree, and MCU unit 3 is fed back to the testing result that diversity factor exceeds set point.
This fault reminding unit 5 controls by the instruction of MCU unit 3 and carries out feature prompting with buzz or caption.
With further reference to Fig. 2, control flow of the present invention is:
1) monitored testing equipment television set or other audio & video equipment are in normal operating conditions.Now carry out straighforward operation definition to ageing tester of the present invention, input remote control manipulative procedure, comprises remote control code, exports remote control command time cycle, device to test number of times or time cycle etc.;
2) by the code that instruction input unit input is consistent with tested equipment, determine that monitored testing equipment can be manipulated by apparatus of the present invention;
3) monitor mode is selected to be that sound monitoring or video capture monitoring or sound and video are monitored simultaneously by instruction input unit;
4) sound monitoring unit is once monitor the limit value of intensity of sound limit value below or above setting, namely to the instruction of MCU unit output abnormality state;
5) there is notable difference, namely to MCU unit output abnormality status command once monitor bitmap that at present shooting stores with the image in a certain setting cycle before in video monitor unit;
6) after MCU unit receives the exceptional instructions of one of both sound monitoring or video monitoring input, output order is to warning reminding unit immediately, output order is to remote-controlled launch unit simultaneously, interrupts remote-controlled launch unit immediately and exports the instruction of monitored testing equipment.The information such as the timing node that record test is interrupted;
7) tested equipment keeps fault present situation, no longer device being tested manipulation;
8) test or experimenter are according to the information of warning reminding unit, at once analyze tested equipment fault phenomenon;
9) if setting time or secondary one number time in, when sound and video all do not detect abnormal, testing apparatus according to test before input instruction works to program determination, complete presetting time and number of times;
For making the technical program openly specifically understand with being convenient to, enumerate three application examples at this:
Implementation example one, 72 hours monitoring television sound aging conditions.
Instruction input unit 7, input monitored testing equipment with hard manual or touch soft keyboard mode to need to carry out sound monitoring test, setting detection 72 hours, when intensity of sound is lower than 30dB, sound monitoring unit 2, mainly carry out environmental sound signal monitoring in pick-up mode, once the limit value that the signal strength signal intensity that pick-up detects sets lower than sound monitoring equipment, namely sound monitoring unit 2 feeds back exceptional instructions to MCU unit 3, MCU unit 3 i.e. output order driving malfunction reminding unit 5, MCU unit 3 interrupts exporting the instruction of remote control command transmitter unit 6 simultaneously, remote control command transmitter unit 6 stops the manipulation to monitored testing equipment 8, tester can immediately according to the prompting that fault reminding unit 5 sends, include but not limited to the prompting of buzz, instant analysis is carried out to the fault of monitored testing equipment.
Implementation example two, 1000 times whether monitoring television repetition tuning image player is normal.
Instruction input unit 7, input monitored testing equipment with hard manual or touch soft keyboard mode to need to carry out video bitmap, setting detection 1000 tuning monitoring, the monitored testing equipment 8 of now remote control is by the normal operating conditions work of setting, remote control command transmitter unit 6 is with the instruction of cycle regular hour remote-transmitter monitored testing equipment repeated priming tuning, the screen signal of video bitmap monitoring unit 4 pairs of monitored testing equipments of property synchronizing cycle carries out shooting and captures, once capture in the signal that captures of video bitmap monitoring unit 4 and a certain cycle before and the signal stored exists notable difference, video bitmap monitoring unit 4 i.e. output order is to MCU unit 3, namely MCU unit 3 exports MCU unit 3 i.e. output order driving malfunction reminding unit 5, MCU unit 3 interrupts exporting the instruction of remote control command transmitter unit 6 simultaneously, remote control command transmitter unit 6 stops the manipulation to monitored testing equipment 8, tester can immediately according to the prompting that fault reminding unit 5 sends, include but not limited to the prompting of buzz, instant analysis is carried out to the fault of monitored testing equipment.
Can implementation example three, working properly after audio-visual synchronization monitoring television repeat switch machine 1000 times; Sound monitoring and video bitmap are monitored completely with above-mentioned two examples, but in logic, once sound or any one unit of video occur abnormal, test is interrupted at once, the timing node of the test generation of retention fault machine and state.
As mentioned above, use the research and development of product of the present invention or quality personnel when carrying out testing authentication to television product or relevant audio and video equipment, efficiently can save manpower, can analog subscriber state promptly and accurately, macrocyclic burn-in test, intelligent fault emulation testing are carried out to product.
The foregoing is only preferred embodiments of the present invention, the present invention is not limited to above-mentioned execution mode, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
