Photosignal, if after detecting echo signal, judging whether the signal is interference signal, and carry out secondary detection, if second
Secondary detection is still echo signal, then system thinks the signal for real detected signal, is otherwise erroneous judgement signal, judges situation by accident
Directly by programming jump to inquiry phase is waited, for real detected signal, the special (flow of counter+1 of internal system
Pencil counting variable+1 in figure), while preserving data, after data processing is finished, process variable is reset, under dolly enters
One signal prepares the reception stage；
2nd, emulated running water line workpiece counting experiments：
Hardware is detected using with identical in emulated running water line workpiece counting experiments system, is spliced with acrylic board and is placed on
Track on the way as tunnel to be measured, dolly orbiting, into after Tunnel testing region, system queries detection tunnel starting letter
Number arrive, if after detecting the signal, judging whether the signal is interference signal, and carry out secondary detection.If second is detected
Still it is echo signal, then system thinks the signal for real detected signal, is otherwise erroneous judgement signal, erroneous judgement situation directly will
Programming jump to etc. the initial signal stage to be checked.For real initial signal, internal system opens special timer, while
Preserve data.Continue to detect end signal, if after detecting the signal, judging whether the signal is interference signal, and carry out two
Secondary detection.If second detection is still echo signal, system thinks the signal for real detected signal, is otherwise erroneous judgement
Signal, erroneous judgement situation is directly by programming jump to wait poll-final signal phase.If being detected real end signal, close
Timer is closed, synchronization process data will and be preserved into memory.After data processing is finished, process variable is reset, dolly
Into next preparation reception stage.
The beneficial effects of the invention are as follows：Can be simple with designed, designed, device, Highgrade integration, modular portable reality
Test equipment, can effective training of students practical operative ability, tentatively reach the requirement of " can design, can adjust, can use ".
