[0060] Step 6: The downstream amplitude detection module reads the downstream amplitude of the module under test 5 to determine whether the downstream amplitude is normal. If so, jump to step 7. If not, jump to step 14.

[0061] Step 7: The inner panel batch number detection module reads the inner panel batch number of the tested module 5 and determines whether the inner panel batch number is correct. If so, jump to step 8. If not, jump to step 14.

[0062] Step 8: The internal board hardware version number module reads the internal board hardware version number of the module under test 5 and determines whether the internal board hardware version number is correct. If so, jump to step 9. If not, jump to step 14.

[0063] Step 9: The upstream signal-to-noise ratio detection module reads the upstream signal-to-noise ratio of the module under test 5 to determine whether the upstream signal-to-noise ratio is within a normal range. If so, jump to step 10. If not, jump to step 14.

[0064] Step 10: The downstream signal-to-noise ratio detection module reads the downstream signal-to-noise ratio of the module under test 5 to determine whether the downstream signal-to-noise ratio is within a normal range. If so, jump to step 11. If not, jump to step 14.

[0065] Step 11: The power consumption detection module reads the power consumption of the module under test 5 and determines whether the power consumption is within a normal range. If so, the process goes to step 12. If not, the process goes to step 14.

[0066] Step 14: Warning light 2 turns on, indicating a corresponding error. Go to step 15.

[0067] Step 15. Save the parameters. Go to step 16.

[0068] Step 16, end.

[0069] The module test control device 4 switches different detection modules in sequence through the module switching circuit to perform a comprehensive detection on the module under test. The working principle is used as a supplement to the intelligent detection scheme in the technical scheme of the present application. It is a common technology in the field and will not be elaborated in detail here.
