Embodiment Construction
[0041] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0042] The present invention proposes a method of implementing a river crab breeding automatic fine bait for achieving the automatic navigation of the vessel vessel speed to measure control, throwing control, and flow controllable, and remaining bait measurable functions. The specific steps include:
[0043] The automatic navigation accommodation is used as a river crab breeding bait operation tool. According to the GPS system, the speed of the ship can be changed in a period of time, and the average motor speed can be achieved by adjusting the speed of the ship, and the speed of the speed is turned on. To achieve the measured control of the speed of the ship ship;
[0044] By performing a bait test, determine the throttle - Popping speed (voltage) relational curve, change the voltage of the pulling motor to change the throttle of the bait, to contr...

The invention discloses a method for realizing automatic fine bait casting for river crab breeding, which is used to realize the functions of an automatic navigation bait casting boat with measurable and controllable speed and flow, controllable throwing amplitude and measurable remaining bait. The invention measures the position change of the ship within a period of time through the GPS system, obtains the average ship speed, and implements closed-loop speed control on the ship speed by adjusting the given value of the ship speed; (voltage) and flow-vibration motor (voltage) relationship curve; install a load cell at the bottom of the feeder, and through the feeding test, determine the gross weight of the feeder - the output voltage relationship curve of the load cell, by measuring the resistance value of the load cell Obtain the remaining bait value; considering the characteristics of deep ditch in the crab breeding pond and no bait in the aquatic planting area, a series of inflection points are used to define the trajectory design. The five parameters of ship speed, bait throw and flow of the straight section of the inflection point are described.
Description
Technical field [0001] The present invention relates to the field of river crab breeding, especially a method of automatic fine bait with river crab breeding. [0002] technical background [0003] In recent years, there are more and more parts of the farming rushed crab, and river crab breeding has become the most rapid development of China's fishery production. [0004] Since river crab breeding has strong geographical restrictions, the river crab does not move a wide range of sports, can only forag in itself; the distribution of bait is uneven and easy to cause excessive amount of payment, and too much bait will not only increase costs It will also lead to water quality pollution; at the same time, struggle and match is the nature of the river crab, the density is large, and the bait will be billed with each other; the over-intensiveness of the river crab is easily reduced in the water body, which causes the river crab to dissolve oxygen And escape. In addition, the bait must b...
