Description
Technical field
It is the invention belongs to systems approach field, in particular to a kind of based on the automatic control for preventing illumination too strong with fish school location
Attracting lamp control method processed.
Background technique
Fish-luring light is the fishing operation ancillary equipment using light source come attracting, can be generally divided into lamp above water and underwater lamp two
Class.Traditional fish-luring light either lamp above water or underwater lamp, control method is all fairly simple, for example, generally by fish-luring light
Power supply line concentration be pulled to distribution box, in distribution box one switch electric brake is installed to every lamp, manual switch electric brake controls
The light on and off of corresponding fish-luring light.This control mode is simple and clear, but lower to the controlling extent of fish-luring light, cannot rationally have
Effect ground control fish-luring light, therefore energy consumption is relatively large, while capture rate is also affected.
Chinese patent CN106900110B provides a kind of control method of fish-luring light, and this method is by using pulsewidth modulation skill
Art adjusts light-source brightness, adjusts the coloration of entire attracting lamp source by adjusting the ratio of red green three kinds of light sources, thus independent
The brightness and coloration for controlling attracting lamp source, cooperate the coloration of light source and brightness preferably, and then improve fish-luring light
Compacting effect improves capture rate, but this still carries out thinking to operate, and seldom has on actual conditions fishing boat and specific takes manipulation
Fish-luring light, and need operator ceaselessly to adjust ratio and reach raising capture rate, it is inconvenient, and people are for a long time 3
It works under the strong light of middle color and is easy to cause eyes irreversible damage, the present invention is automatically adjusted by the position of the shoal of fish
PWM value achievees the effect that adjust brightness, and detects human body signal and whether reach condition and be inserted into new PWM value and reduce original PWM,
Reduce injury of the strong light to human body to the greatest extent the case where not reducing capture rate.
Summary of the invention
It is an object of that present invention to provide a kind of based on preventing the too strong automatic control fish-luring light control with fish school location of illumination
Method, the PWM that the change in location by detecting the shoal of fish automatically adjusts fish-luring light reaches the amount brightness for adjusting attracting, and passes through inspection
Survey whether the time existing for human body signal reaches condition to adjust new PWM value and reduce to the greatest extent the case where not reducing capture rate by force
Injury of the light to human body.
It is a kind of to be lured based on the automatic control attracting lamp control method for preventing illumination too strong with fish school location, including described in acquisition
Human body signal around fish lamp, acquisition first area, second area, third region, the light of the fourth region and the 5th area lights
Light overlay area, the first area light cover upper area, and the second area is that light covers lower section second area, institute
Stating third region is that light covers left area, and the fourth region is that light covers right region, and the 5th region is lamp
Light covers central area, connects shoal of fish sonar detection device, and the shoal of fish sonar detection device detects the light overlay area shoal of fish
Area, based on the first area, second area, third region, the fourth region light covering surface shoal of fish area and the 5th
The light area coverage in region and the variation judgement of shoal of fish area adjust the PWM value of the fish-luring light, and according to firstth area
Domain, second area, third region, the brightness value of the light of the fourth region and the 5th region light overlay area and shoal of fish area
The PWM value of the fish-luring light is readjusted in variation；Simultaneously according to the position of the shoal of fish and human body signal duration T judgement
Automatic adjustment is better than the PWM value of lamp.
Wherein by fish-luring light, area coverage is divided into five regions around ship, wherein the first area, second area,
Third region, the fourth region are trapezoid area, and the 5th region is rectangular rectangle region, and five regions form a rectangle,
The length and width of rectangle are that the area that fishing boat is casted net determines, connect the shoal of fish sonar detection device, the shoal of fish
The shoal of fish area that sonar detection device will test five regions distinguishes the first sub-value of area of detection S1, S2, S3, S4 and S5 pairs
The shoal of fish sonar detection includes:
S01: when the area of detection S1+S2+S3+S4 is greater than the S5, promoting the PWM value of the fish-luring light to normal value,
It is not made a decision if being normal value if the PWM value of the fish-luring light；
S02: when collecting the human body signal, and the human body signal value duration reaches pre-set value T, wherein time T
For the preset in advance fixed time, the PWM value of presently described fish-luring light is obtained, a new PWM is generated according to initial p WM at random,
And it is adjusted to new PWM, adjustment time is the time generated at random in (0, T), and time reception is restored to original PWM
Value；
S03: it when the area of detection S1+S2+S3+S4 is less than in the S5, reduces the PWM value of the fish-luring light and obtains second
Sub-value SC1, SC2, SC3, SC4 and SC5.
Wherein, second of fishing zone area SC1, SC2, SC3, SC4 and SC5, the SC1, SC2, SC3, SC4 are obtained
With, SC5 be respectively first area, second area, third region, the fourth region and the 5th region second of shoal of fish face
It is long-pending, include: to the shoal of fish sonar detection
S11: when the SC1+SC2+SC3+SC4 is greater than the SC5, the PWM value of the fish-luring light is promoted to normal value；
S12: when collecting the human body signal, and the human body signal value duration reaches pre-set value T, wherein time T
For the preset in advance fixed time, the PWM value of presently described fish-luring light is obtained, a new PWM is generated according to initial p WM at random,
And it is adjusted to new PWM, adjustment time is the time generated at random in (0, T), and time reception is restored to original PWM
Value；
S13: it when the SC1+S2C+SC3+SC4 is less than the SC5, reduces the PWM value of the fish-luring light or waits fishing
Ship seine signal;
S14: when the S5 is greater than the SC5, and when meeting in the condition of front three any one, the PWM of the fish-luring light
Return to normal value；
S15: when the S5 is less than the SC5, and when meeting in the condition of front three any one, the fish-luring light without
It adjusts.
Wherein, the first area, second area, third region, the light of the fourth region and the 5th region light are obtained
Brightness value fl1, fl2, fl3, fl4 and the fl5 of overlay area include: for the control of five region detections
As the fl1, fl2, fl3, fl4 and fl5 increase, and the SC1+SC2+SC3+SC4 is less than the S1+S2+S3+S4, control
The PWM value for making the fish-luring light is constant；
As the fl1, fl2, fl3, fl4 and fl5 increase, and the SC1+SC2+SC3+SC4 is less than the S1+S2+S3+S4, control
The PWM value for making the fish-luring light reduces；
