Sampling System,
,
The UAV nearshore environmental comprehensive sampling system adopts the “UAV +” mode, which combines software and hardware. The hardware part uses independently controllable drones, descenders, samplers and other equipment, and the software part has fixed-point hovering, fixed-point sampling and other functions. It can solve the problems of low sampling efficiency and personal safety caused by the limitations of survey terrain, tide time, and physical strength of investigators in nearshore or coastal environmental survey tasks. This solution is not limited by factors such as terrain, and can accurately and quickly reach the target station to carry out surface sediment and seawater sampling, thereby greatly improving work efficiency and work quality, and can bring great convenience to intertidal zone surveys.

Frankstar UAV sampling system supports sampling within a maximum range of 10 kilometers, with a flight time of about 20 minutes. Through route planning, it takes off to the sampling point and hovers at a fixed point for sampling, with an error of no more than 1 meter. It has a real-time video return function, and can check the sampling status and whether it is successful during sampling. The external high-brightness LED fill light can meet the needs of night flight sampling. It is equipped with a high-precision radar, which can realize intelligent obstacle avoidance when driving on the route, and can accurately detect the distance to the water surface when hovering at a fixed point.

Features
Fixed point hovering: error does not exceed 1 meter
Quick-release and install: winch and sampler with convenient loading and unloading interface
Emergency rope cut-off: When the rope is entangled by foreign objects, it can cut the rope to prevent the drone from being unable to return.
prevent cable rewinding/knotting: Automatic cabling, effectively preventing rewinding and knotting

Core parameters
Working distance: 10KM
Battery life: 20-25 minutes
Sampling weight: Water sample: 3L; Surface sediment: 1kg
