1. a kind of spilled oil monitoring method, it is characterised in that the spilled oil monitoring method includes:

  • S1, within the first sampling period, first band optical signal to the target area without ultraviolet source irradiation is sent, to obtainFirst background value;

    S2, within the second sampling period, first band optical signal to the target area without ultraviolet source irradiation is sent, to obtainSecond background value and first band optical signal is sent to by ultraviolet source irradiation target area, to obtain the first signal value;

    S3, difference operation is made according to second background value and first signal value, it is corresponding to obtain for the second sampling periodFirst signal difference;

    Whether more than lower threshold and less than upper limit threshold, the upper limit threshold is configured first signal difference described in S4, comparingIt is the signal difference of the pure oil obtained in laboratory test, the lower threshold is configured as in the bar without oil spilling or other impurityUnder part, the value of the sea signal difference 30%~50% for measuring is higher by;

    If so, then performing step S6;

    If it is not, not alarming then;

    S5, the actual ratio for calculating second background value and first background value, judge whether the actual ratio is less thanThe reference ratio, the reference ratio is configured as one and refers to constant, if so, then performing step S6;

    If it is not, not alarming then;

    After S6, time delay, step S7 is continued executing with;

    S7, detection obtain the 3rd background value and secondary signal value after time delay, and are calculated the secondary signal difference after time delay;

    Whether secondary signal difference described in S8, comparing is more than the lower threshold and less than the upper limit threshold;

    If so, then reportingIt is alert;

    If it is not, not alarming then.
