Fig. 4 is according to the schematic diagram of the application scenarios of the concrete example of the embodiment of the present invention.As shown in Figure 4, in test cabinet, place 2 TV201 that will simultaneously test and TV202.TV test macro 203 is tested TV201, and TV test macro 207 is tested TV202.TV test macro 203 comprises video camera 204, infrared remote control equipment 205 and PC 206.The application program of TV test macro 203 is moved on PC 206, and video camera 204 is connected with PC206 with infrared remote control equipment 205.Tester can set test parameter by PC 206, and test result can be stored in PC 206.TV test macro 203 obtains the screen picture of TV201 from video camera 204.System 203 is processed these images, to judge that whether test is successful.At test period, system 203 is used infrared remote control equipment 205 to operate TV201.For example, in the time carrying out channel switch test, infrared remote control equipment 205 changes the channel of TV 201.TV test macro 207 is forming and is operating identical with TV test macro 203.PC 211 derives from TV defect or flase drop signal for judging the failure result that TV test macro 203 or 207 detects.If PC 211 judges that failed test result is from flase drop signal, PC 211 gives a warning, for example, show alert message, open buzzer, send PC from alert message etc. to tester or mobile phone.If the performance of PC is enough, PC 206,210 and 211 can be incorporated in a PC, or PC 206 can intercom mutually with 210, and without PC 211.
Fig. 5 is according to the structured flowchart of a part for the concrete example test equipment of the embodiment of the present invention, and corresponding to aforesaid operations portion 11, input part 12 and handling part 13, these can be the software modules of the TV test macro that moves on PC206.Camera control module 301 can be set the attribute of video camera 204 and obtain image from video camera 204.The attribute of video camera 204 mainly comprises brightness, contrast, gain, focusing, image resolution ratio and image frame per second.The high quality graphic of TV 201 contributes to improve the accuracy of test result.Algoritic module 302 provides the interface of multiple image processing algorithm.The parameter of algorithm and the parameter of test cases can be kept in configuration file 307.In the time that the application program of TV test macro 203 is moved on PC 206, configuration module 308 can read parameter from configuration file 307.IR code file 305 is stored the coded format of test signal.Infrared remote control equipment 205 can generate test signal and operate TV 201 by the test signal coded format of storage in IR code file 305.In the time sending TV signal to TV201, remote control module 303 can be controlled infrared remote control equipment 205.Test cases 306 comprises test command.Parsing module 304 is resolved test cases 306 and is obtained test command.Parsing module 304 can call in algoritic module 302 corresponding image processing algorithm according to test command and process the image that video camera 204 is taken, and calls remote control module 303 and controls infrared remote control equipment 205 and send test massage to TV 201.At test period, if TV 201 receives the test signal from another TV test macro 207, test result is incorrect.To this, test result is sent to PC 211 by authentication module 309.The correctness that on PC 211, the test and management system 801 of operation can validation test result.Test output 310 can comprise image file, video file, audio files and journal file.Image management module 311 can be stored TV image temporarily.If test result is incorrect, the associated picture of PC 211 in can reference picture management module 311.Or image management module 311 also can be stored the binaryzation data (for example, 1: bright screen, 0: blank screen) of the image obtaining according to camera control module 301.PC 211 controls TV test macro 203 via control module 312.For example, in the time that PC 211 will stop or suspending test, PC 211 sends the instruction that stops test or suspend test to control module 312, and control module 312 is carried out corresponding control.
Fig. 6 is according to the structured flowchart of another part of the concrete example test equipment of the embodiment of the present invention, and corresponding to above-mentioned comparing section 14 and notification unit 15, these can be the software modules of the TV test macro of operation on PC 211.As shown in the figure, memory module 805 is for storing correct test result.If be correct from the test result of authentication module 309, by result store in memory module 805.Table in Fig. 7 and Fig. 8 is the example of storage format in memory module 805.Table in Fig. 7 is preserved TV in test and is received the orthochronous that the laggard line operate of test signal uses.For example, in channel switch test, the table in Fig. 7 represents the time that channel handover operation is used.If receive new orthochronous from authentication module 309, this new time is added in the table of Fig. 7.Tabular in Fig. 8 has gone out fiducial time.Can use standard time in TV specification as fiducial time.For example, if manufacturer knows that the standard time of A model TV start operation is 3s, can in row 1501, write 3s.Because the standard time in TV specification may be slightly different from the real time, so the mean value of multiple orthochronous in preferred Fig. 7 table.For example, the value shown in 1502 is the standard time of A model TV channel handover operation, and this standard time can be for example according to the mean value from time 1401 to 1405 calculating gained in Fig. 7 table.In the time of test result mistake, error detection module 802 is called comparison module 803.Comparison module 803 will be compared from the image of image management module in PC 206 and PC 210.If comparison module 803 misjudgment results derive from flase drop signal, notification module 804 sends judged result.In addition,, if test and management system 801 need to stop or suspending test to show error result, comparison module 803 generates and stops test or suspend the instruction of test and instruction is sent to the control module in PC 206 or PC 210.Notification module 804 can be notified flase drop signal has occurred, for example, show alarm, start buzzer, send PC from alert message etc. to test man or mobile phone etc.
Fig. 9 shows the operating process of carrying out in the comparison module of concrete example test equipment.At S1201, comparison module 803 receives the rub-out signal from error detection module 802, and at S1202, comparison module 803 obtains binary image status data from adjacent TV test macro.Or if comparison module 803 has the function of processing image, comparison module 803 can generate binary image status data according to the image of storage in image management module 311.After being ready to binary image status data, at S1203, comparison module 803 compares binary image status data, with the similarity of check image state.After check image state similarity, at S1206, comparison module 803 determines whether the TV being compared is same model.Due to the specification difference of different model TV, for example time of switching channels, machine open/close time, these differences can affect the inspection of image state similarity.If the TV comparing is dissimilar, at S1207, the correct test result that comparison module 803 uses in memory module 805 storage as a reference, is eliminated due to the error of the different brings of TV model to image state similarity.At S1204, by judging that whether similarity is higher than threshold value, determine whether mistake derives from flase drop signal.If similarity is higher than threshold value, comparison module 803 determines that error source is in flase drop signal.At S1205, comparison module 803 sends notification signal to notification module 804.
The following describes in comparison module 803, how misjudgment comes from signal interference.For easy to understand, adopt channel switch test case as example.
In channel switch test, test TV and be switched to another channel required time from a channel and whether meet specification requirement, and whether show error image at test period.Figure 10 shows the normal processes that is switched to channel n+1104 from channel n 102.In Figure 10, in the time receiving channel switching signal 101, TV can not be switched to channel n+1104 immediately, but need to wait for after several seconds just can indicated channel n+1104 image.This stand-by period is called switching time 105.During switching time 105, most of TV show blank screen 103.After the image of indicated channel n+1104, also there is stabilization time 106.Total time 107 is summations of switching time 105 and stabilization time 106.The time-out time (be called and judge time-out time 108) of setting contents of channel handover operation is 10s, be 3s stabilization time, if this expression total time 107 is less than 10s, and do not glimmer or blank screen within stabilization time 106, be switched to the operation success of channel n+1104 from channel n 102.
The example of TV signal when Figure 11 shows test crash in channel switch test.In Figure 11, within switching time and stabilization time, all there is image flicker, as shown in 901 and 902.In this case, TV test macro judges that the test result that this channel switches is mistake.
Figure 12 shows two TV while carrying out channel change detection, and TV flase drop is to TV signal example in test signal situation.TV201 receives the test signal from infrared remote control equipment 209 in another TV test macro 207 within stabilization time.In this case, TV201 cannot show image (referring to Figure 12 (a) signaling point 1001) continuously in stabilization time, and TV test macro 203 judges that the test result that this channel switches is mistake.After signaling point 1001, TV201 image state is identical with TV202 image state (referring to Figure 12 (b)).According to the embodiment of the present invention, in comparison module 803, compare two TV image states, if after signaling point 1001, two TV image state similarities are higher than threshold value, comparison module 803 determines that wrong test result derives from flase drop signal.Figure 13 shows two TV while carrying out channel switch test, and TV flase drop is to another example of TV signal in test signal situation.TV201 receives the test signal from infrared remote control equipment 209 in another TV test macro 207 within switching time.In this case, required time of TV201 switching channels is longer than normal switching time, if so, and because TV201 cannot switch by completing channel in the overtime time limit of judgement of regulation, so TV test macro 203 also can be judged test result mistake.According to the embodiment of the present invention, in comparison module 803, compare two TV image states.If after signaling point 1102, two TV image state similarities are higher than threshold value, and comparison module 803 decision errors derive from flase drop signal.
Consider that the TV of test is the situation of different model simultaneously, refer again to above-mentioned two examples.For receive flase drop signal within stabilization time, even if TV is different model, after signaling point 1001, TV image state is also identical, referring to Figure 12.Therefore TV model can not have any impact to judged result.For receive flase drop signal within switching time, if TV is same model, show that point 1101,1102 is identical, referring to Figure 13.If TV is different model, signaling point 1302 and 1304 is not identical, referring to Figure 14.In Figure 14, the signaling point 1301 that TV201 actual channel switching required time deducts average channel switching time (coming from memory module 805) is the time that TV201 receives incorrect TV signal.Time point 1301 and 1303 is compared, if both approach, think error checking result source flase drop signal.
According to the embodiment of the present invention, notification source is from the mistake of flase drop signal in time.The method also can be used for other tests, for example machine open/close test.In addition,, although described the embodiment of the present invention in conjunction with the concrete example of 2 TV above, the embodiment of the present invention can be applied to more TV.
Although utilized example embodiment to describe the disclosure, can those of ordinary skills it is contemplated that multiple variation and modification.The disclosure is intended to contain to fall these variations and modification within the scope of the appended claims.
