The invention relates to the technical field of weather forecast inspection, in particular to a weather forecast inspection method and system based on skill score and mode comparison, and the method comprises the steps: obtaining hourly observation description, extracting time difference and element features, forming an observation time sequence, matching station numbers, and paralleling forecast elements to generate a forecast alignment sequence; and extracting a rainfall grade difference sequence, merging according to regions to form a region grade difference sequence, comparing a difference sequence direction to generate a region comparison score sequence, integrating multi-element difference values, and outputting a test conclusion according to a sorting reference. According to the method, the time sequence coherence is enhanced through hourly observation check and integration; an extreme value, a peak value and a grade are extracted, so that observation is expanded from a single point to a time sequence with amplitude and grade; station matching is carried out to eliminate invalid data to ensure centrality; merging an error by using the grade serial number and the region code, and presenting a region deviation trend; the multi-element differences are integrated to form regionalized, directional and hierarchical combined features, and the mode difference contrast level is enhanced.

This application discloses a soft-start control circuit, method, device, and auxiliary lamp for a lamp module. The soft-start control circuit relates to the field of auxiliary lamp control technology. The soft-start control circuit includes: a switching transistor drive circuit; a switching transistor circuit including at least one switching transistor, with its input connected to the drive circuit and its output connected to the control terminal of the lamp module; and a main control module, whose output is connected to the drive circuit. The main control module receives the lamp module's on / off signal and outputs a control signal, causing the drive circuit to periodically control the switching transistor in the drive circuit to turn on and off according to the control signal until the duration of the main control module's output control signal reaches a target time. This application improves the reliability of lamp module control.

The present invention relates to a preservative-free, aqueous solution in the form of eye drops packed in a container that ensures stability of the product, ideal eye drop volume and reduced drop volume variability and provides efficient dispensing.

The invention discloses a cable fault abnormal data self-checking method and system based on multi-source traveling wave comparison, and relates to the field of power system protection and fault diagnosis. Under the condition that sampling clocks are inconsistent, overlapped data segments which can be mutually correlated are formed through same-window triggering collection and caching; performing wave head transient feature extraction on the multi-phase sheath traveling wave, obtaining the relative time difference of each channel by using cross correlation, and constructing a relative time difference matrix and an energy ratio matrix in combination with a wave head neighborhood energy ratio; generating a normalized reliability weight according to the signal-to-noise ratio and the energy consistency, jointly estimating the arrival time of each channel wave head in a weighted iteration time estimation model, identifying and correcting outlier abnormal data, and obtaining a self-checked arrival time sequence; and the position / segment length of the grounding box and traveling wave propagation velocity mapping are combined to output the position of a fault point. As a result, reliable positioning without high-precision synchronization is achieved.
