| Interval numbering | Rule of judgment | Operational mode |
| Interval 0 | LC>TQ1 | Normal operation |
| Interval 1 | TQ4≤LC<TQ2 | Display screen is low bright |
| Interval 2 | LC<TQ4 | Enter Night |
In above-mentioned table 1, Night comprises reduction wind speed (such as wind speed * PS), display screen display is closed, buzzer prompt tone reduces half etc.The low bright display brightness reduction referring to display screen of display screen, is preferably reduced to the half of former brightness.
Wherein, described TQ3=0.9*A+Hmin, TQ4=0.5*A+Hmin.A is light minimum brightness AD value, and Hmin is AD value of turning off the light, and the span of this Hmin is [0,30].
Be understandable that, above-mentioned Hmin can for fixing value, but in order to more accurately to the judgement of Night, the self study that the embodiment of the present invention can comprise two stages corrects.As shown in Figure 1, concrete trimming process is as follows:
Step S101, judgement are first stage study or second stage study, if first stage study then enters step S102, if second stage study then enters step S103;
Step S102, will learn value range CRANG=TSRANG1, preset study number of times TCN=SCN1, preset interval time TS=TS1, enters step S104;
Step S103, will learn value range CRANG=TSRANG2, preset study number of times TCN=SCN2, preset interval time TS=TS2, enters step S104;
Step S104, with preset interval time, periodically gather present intensity value LC, enter step S105;
Step S105, judge whether cumulative number CTN is greater than default number of corrections TCN, if be less than, enter step S106, if be greater than, enter step S108;
Step S106, judge whether present intensity value LC is positioned at study value range CRANG, if enter step S106 within the scope of study, if not within the scope of study, then perform step S109;
