Description
Technical field
The present invention relates to vegetation protections, and in particular to the emphasis vegetation protection device based on Fibre Optical Sensor.
Background technology
Vegetation refers to the phytobiocoenose that a certain area of earth surface is covered.It is divided according to type of plant communities, grassy marshland can be divided into
Vegetation, forest cover etc..The natural environmental elements such as it and weather, soil, landform, the animal kingdom and aqueous condition are closely related.From complete
Ball range can divide into ocean vegetation and land vehicles two major classes.But since terrestrial environment difference is big, thus form a variety of plants
By type, the multiclass classifications such as vegetation type, plant formation and association series can be divided into.Natural vegetation and artificial can be also divided into
Vegetation.Artificial vegetation includes farmland, orchard, grassland, plantation and urban green space etc..Natural vegetation includes natural vegetation, secondary
Vegetation etc..Worse and worse due to present environment, and endangered vegetation type is also more and more, and government increasingly payes attention to
Emphasis vegetation protection.
Invention content
In view of the above-mentioned problems, the present invention provides the emphasis vegetation protection device based on Fibre Optical Sensor, the present invention is applying
When can to emphasis vegetation carry out real-time guard, when there is human or animal close to vegetation, will immediately learn.
