Demarcation signal SEmpty；By all demarcation signal SThere is thingFlock together to form aggregate signal SThere is thing, by all demarcation signal SEmptyAggregation
Aggregate signal S is formed togetherEmpty, by aggregate signal SThere is thingWith aggregate signal SEmptyFlock together to form aggregate signal S2；
Off state monitoring step：Detect under LED lighting body off state due to signal S3 caused by photic electric principle；Letter
Number S3 include signal S31 caused by monitoring first row LED lighting body ..., monitor the generation of last row LED lighting body
Signal S3N；
Analyze judgment step：Comparison signal S3 and aggregate signal S2 is blurred, is chosen closest with signal S3 in aggregate signal S2
Signal, analyze the state closest to signal, judge whether the photic electric induction interface of LED lighting body has object；Using letter
Number S31 ..., signal S3N respectively with aggregate signal SThere is thingCarry out fuzzy matching；When signal S31 fuzzy matching is arrived and aggregate signal
SThere is thingIn some immediate value when, record moment T1；……；When signal S3N fuzzy matching to aggregate signal SThere is thingIn most connect
During some near value, moment TN is recorded；Arrange moment T1 ..., moment TN size order, when moment T1 is less than moment TN
When, then can be determined that object is to move towards last row from first row, when moment T1 is more than moment TN, then can be determined that object is
First row is moved towards from last row.
8. based on the detection method described in claim 7, it is characterised in that judge the photic electric induction interface of LED lighting body
When whether having object, when there is object, the feature of judgment object；When without object, external environment condition feature is judged.
