Fattening pig house environment regulation and control system and method

Abstract

The invention discloses a fattening pig house environment regulation and control system and method. The system comprises a detection unit, a control unit and a monitoring center. The detection unit detects temperature, humidity, air flow and ammonia of a fattening pig house. The control unit controls control equipment through utilization of PI secondary regulators. The monitoring center circularlyreads temperature, humidity, air flow and ammonia parameters of a fattening pig house environment collected by the detection unit, designs a single-neuron adaptive PSD controller+ a neuron decouplingcompensator to form a fattening pig house environment master regulator for the temperature, the humidity, the air flow and the ammonia, and realizes effective control over the temperature, humidity,air flow and ammonia of the fattening pig house environment. The detection unit detects the temperature, humidity, air flow and ammonia of the fattening pig house through utilization of sensors. Inputof the PI secondary regulators of the control unit comes from output of the neuron decoupling compensator of the monitoring center, thereby forming a multi-cascade control system of the master and secondary regulators.

Description

technical field [0001] The invention relates to the technical field of agricultural animal husbandry automation equipment, in particular to an environment control system and method for a fattening pig house. Background technique [0002] With the rapid development of the modern pig industry, the scale and standardization of pig farming are getting higher and higher, and the environment of the fattening pig house has an increasingly obvious impact on the healthy growth of pigs, pork quality, pig welfare and reproductive performance. It is an important link to improve the economic benefits of pig farming to provide a good and suitable growth environment for pig growth, to ensure the healthy growth of pigs, and to ensure the quality and safety of pork. However, in recent years, as the disease resistance and health level of pigs have shown a downward trend, it is necessary to adjust the environmental control objectives and control strategies of the fattening pig house in a timel...

Problems solved by technology

The above systems have promoted the rapid development of the pig industry, but these control systems have not combined the characteristics of multi-variable, nonlinear, strong coupling, large hysteresis and large inertia in the environment of the fattening pig house to fundamentally solve the problem of unstable environmental parameters of the fattening pig house, Problems such as low control precision and slow system response speed, and it is impossible to predict the change trend of ammonia concentration in the house
