If the set-top box passes the test, the set-top box keeps outputting the tone signal (such as 1K Hz tone) from the audio interface, and if the set-top box does not pass the test, the set-top box suspends and stops transmitting the tone signal; or the set-top box keeps outputting the tone signal (such as 1K Hz tone) from the audio interface if the test fails, and suspends and stops delivering the tone signal if the test passes. After the test is passed, judging whether the test cycle times are reached after the test, if the test cycle times are reached after the test, finishing the execution of the self-checking program by the set top box; if the number of test cycles has not been reached after the test, the test case n +1 continues to be executed.
The output tone signal is mainly used for distinguishing a test result after the set top box executes the test case, so that the output tone signal can be output only when the set top box passes the test or only when the test fails. The single-tone signal adopted by the embodiment is mainly considered based on the structure of the set-top box, and the single-tone signal is selected mainly because the single-tone signal is output, so that the whole processing process of the high-temperature aging test is simpler; of course, other audio signals may be output, but the whole process becomes complicated.

specifically, under the control of the main control unit, after the set-top box in the tray starts to execute the self-checking program, the corresponding rack state indicating unit starts to detect the test result state of the set-top box through the tray state indicating unit and feeds the test result state back to the main control unit. The test jig mainly comprises a rack state indicating unit, a tray state indicating unit and trays, wherein each test jig corresponds to one rack state indicating unit, and each tray corresponds to one tray state indicating unit.

And step S22, the main control unit receives the test result of the tested set top box determined by the tray state indicating unit, wherein the test result is obtained and fed back from the storage unit by the downlink communication unit based on the obtaining instruction.
After each tested set top box in the tray executes a test case of the self-test program, an audio signal is sent to the tray state indicating unit according to different test results, and the audio signal sent by the set top box after the tray state indicating unit tests is used for determining the test result of the set top box and sending the test result to the downlink communication unit; the downlink communication unit receives the test result of the set top box and then caches the test result to the storage unit; the uplink communication unit acquires the test result of the set top box from the storage unit after receiving an acquisition instruction which is sent by the main control unit and acquires the test result of the set top box after test, and reports the test result of the set top box to the main control unit through a bus; the main control unit receives the data reported by the uplink communication unit, and further, the main control unit can display the data, for example, the test state of each set top box is displayed through a screen. The main control unit can also upload the test result data to a database or a cloud server, so that the process management and control are realized.
In this embodiment, the test result of the tested set top box is determined by the tray state indicating unit, the tray state indicating unit reports the test result of the set top box to the rack state indicating unit, the rack state indicating unit reports the test result of the set top box to the main control unit, the state indicating unit reports information in a grading manner, the processing pressure of the main control unit is greatly relieved by a cache architecture, and the hardware configuration requirement of the main control unit is reduced; compared with the conventional machine vision system, the state indication method is simple in implementation method, low in development difficulty and low in cost, and the production cost of the set top box is greatly reduced; by reporting the grading information, batch set top boxes can be detected, the indicating efficiency is high, and the production efficiency of the set top boxes is greatly improved.

step S40, the main control unit obtains the number of defective products of the tested set top box in the tray matched by the tray state indicating unit according to the test result;
when a certain set top box in a certain tray fails to pass the test, the voice port of the certain set top box stops sending out a single-tone signal, the tray state indicating unit corresponding to the set top box which fails to pass the test reports the state of the set top box to the corresponding rack state indicating unit, and the rack state indicating unit reports the state of the set top box to the management main control unit; the main control unit can monitor the number of trays of each test rack, the number of set top boxes in each tray and the test state of each set top box; furthermore, the main control unit displays the received data, and the state of each set top box displayed by the main control unit can be seen manually.
And step S50, when the number of defective products reaches a preset threshold value, the main control unit controls the conveying unit to output the defective set top boxes in the paired trays to the blanking unit.
When the number of defective set top boxes in a certain tray reaches a preset threshold value, namely when the number of set top boxes which do not pass the test in the same tray reaches the threshold value, the main control unit sends related address information to the conveying unit, and the conveying unit takes the corresponding tray to the blanking area according to the related address information; the state of the set top box displayed by the main control unit can be seen manually, then the defective set top box in the tray is taken down according to the state of the set top box displayed by the main control unit, and after the set top box is replaced with a new set top box, the defective set top box is sent back to the test frame for high-temperature aging test.

step A1, the tray state indicating unit acquires audio signals sent by each tested set top box in the paired trays based on self-test results;
and if the set top box passes the test, the set top box keeps outputting the audio signal from the audio interface, if the set top box does not pass the test, the set top box suspends and stops transmitting the audio signal, and the output audio signal is transmitted to the signal conditioning unit of the tray state indicating unit through the pairing tray (namely, the tray correspondingly connected with the set top box). And the tray state indicating unit acquires an audio signal sent by the tested set top box. Specifically, the set top box under test executes each test case, the set top box keeps outputting a single-tone signal (such as a 1K Hz single tone) from the audio interface when the test is passed, suspends and stops transmitting the single-tone signal when the test is not passed, and the output single-tone signal is transmitted to the signal conditioning unit of the tray state indicating unit through a pairing tray (i.e., a tray correspondingly connected to the set top box). The tray state indicating unit acquires a single tone signal sent by the set top box after the detection.
Step A2, the signal conditioning unit conditions the waveform of the audio signal to obtain a waveform signal containing the self-test result of each tested set top box in the matched tray;
the signal conditioning unit is used for carrying out waveform conditioning, such as level amplification, filtering and the like, on the input audio signal, so that the audio signal which passes through the test and does not pass through the output of the set top box is converted into a waveform signal which can obviously indicate that the set top box passes through the test or does not pass through the test after the waveform conditioning is carried out on the audio signal, and then the signal detection unit can clearly identify the audio signal.
And step A3, detecting the waveform signal by the signal detection unit, determining that the tested set top box is a good product or a defective product, and obtaining a test result of the tested set top box.
After the waveform signal is transmitted to the signal detection unit, the signal detection unit detects the waveform signal and converts the waveform signal into an IO state signal (for example, 1 code has an audio signal, and 0 represents no audio signal), and then the signal detection unit sends the IO state signal to the communication unit. In this embodiment, the set top box keeps outputting the audio signal when the test is passed, and stops outputting the audio signal when the test is not passed, and the signal detection unit detects the waveform signal and converts the waveform signal into an IO state signal, that is, whether the set top box outputs the audio signal is detected, thereby determining that the set top box is a good product or a defective product, and obtaining a test result of the set top box after the test.
The communication unit reports the IO state signal to the rack state indicating unit through the bus, the data is cached through the storage unit of the rack state indicating unit, the IO state signal is sent to the main control unit of the high-temperature aging test management through the uplink communication unit of the rack state indicating unit and the bus, and the main control unit displays the data.
In the embodiment, after the set top box is tested, the test result of the set top box is indicated by outputting the audio signal; the tray state indicating unit determines a test result of the set top box according to the audio signal, performs state indication on the test result of the set top box through an IO state signal, reports the state indication to the rack state indicating unit, and reports the state indication to the main control unit through the rack state indicating unit; the state detection reliability is high, the error judgment rate of the indicating method approaches zero, and the machine vision system generally has more than one thousandth of error judgment, so that the detection error caused by judgment by the machine vision system is avoided, the detection accuracy rate is improved, and the production quality is further improved.
