Abstract
Along with the development of animal husbandry industry, all kinds of large-scale farms
everywhere, the mechanization of farming has become the mainstream of today's farming.
Artificial breeding of previous time-consuming and laborious, and the breeding efficiency is very
low, the benefits of cultivation has also made the boss if.
With the development and application of single chip embedded technology has met the demand of
aquaculture. Now the plant breeding is the system feeding system and the system of drinking water system,
few people can meet the operation problem of drinking water for all plant. Therefore, the water tower water
drinking system plant breeding is key to these aquaculture plant. So, if a water tower water system of
ultrasonic water level control system of single-chip microcomputer is applied to the aquaculture industry based,
it will bring new vigor and vitality to the aquaculture industry. Ultrasonic water level control system of water
level measuring tower to non-contact height, compared to the previous contact measurement has many
advantages. Ultrasonic in the same medium propagation speed is relatively stable and when the ultrasonic
obstacle when reflection occurs, according to the physical sense of corresponding is easy to measure the height
of the water level in a water tower, and the ultrasonic wave is not affected by the influence of measured object
light, color, and in the dark, to smoke, dust, toxic, high altitude harsh conditions and have strong adaptability.
The ultrasonic water level control system changed the artificial water pumping, climb the
tower observation work, the system can automatically detect the water level height, and each
plant breeding can according to their own requirements for the height of the water aquaculture,
set the upper limit and lower limit water level. When the water level is below the limit, it will
automatically pumping water, when the water level is higher than the upper limit will be
automatic drainage, the water level control in a certain range. So the ultrasonic water level
control system of single-chip microcomputer has the advantages of simple operation of human
nature, based on convenience convenience, can meet the need of breeding plant breeder. The
demand is very suitable for modern plant breeding time, can the promotion.
