Brooder temperature control method based on process neural network

Abstract

The invention discloses a brooder temperature control method based on a process neural network. The brooder temperature control method comprises the following steps: performing temperature acquisition and data fitting; taking the acquired and fitted temperature function as input of the process neural network, and predicting the temperature of the next second of the current time by employing the process neural network; subtracting the predicted brooder temperature value at the next second of the current time from the expected temperature value by to obtain temperature deviation, performing proportion integration differentiation (PID) control adjustment on the temperature deviation, controlling a temperature regulator in the brooder, and regulating the temperature at the next second in the brooder. The temperature in the brooder is sequentially acquired, subjected to data fitting and is predicted and controlled, the set value can be closely tracked by the brooder temperature, the brooder temperature is kept in a range of 0.3 DEG C around the given temperature, the fluctuation is small, and the hatching rate and hatching quality are greatly improved.

Description

technical field [0001] The invention belongs to the field of hatching control and relates to a method for controlling the temperature of a hatching room based on a process neural network. Background technique [0002] With the continuous improvement of people's living standards, the demand for poultry (such as chickens, ducks, geese, pigeons, etc.) has increased significantly. In order to meet people's demand for meat poultry, it is necessary to carry out large-scale meat poultry hatching. In the hatching process of poultry eggs, it is necessary to ensure that the fertilized eggs become high-quality chicks as much as possible. Temperature is the decisive factor that determines the success of hatching. Can improve chick quality. [0003] The hatching process of poultry eggs is a highly nonlinear, large-delay, time-varying, and strongly coupled agricultural production process, and the temperature of the hatching process is often affected by uncertainty and randomness such as...

AI Technical Summary

Problems solved by technology

[0003] The egg hatching process is an agricultural production process with highly nonlinear, large lag, time-varying characteristics and strong coupling, and the temperature of the egg hatching process is often affected by uncertainty and randomness such as ventilation, power grid fluctuations, and peripheral equipment. Due to the influence of sexual factors, it is difficult to establish an accurate mathematical model of the hatching process of poultry eggs. The current hatching equipment adopts traditional control methods, but the model of the hatching process has not been established, and the temperature during the hatching process of poultry eggs cannot be well guaranteed. stability control
