Currently, a lot of human resources are required to get rid on poultry farms from viruses and determining the fertility of chicken embryos with three states: live, dead and weak, and then take measures to increase hatching. The article discusses an artificial neural network (ANN) structure to automate the monitoring of the chicken eggs development with identifying viable embryos. A technique for separating the chicken eggs area to sectors to automate the ovoscoping process has been developed. The structural scheme of the artificial neural network contains a set of synapses, each of which is characterized by its weight. Synapses input signals are multiplied by weight and folded by adder. When adding, a threshold is also taken into account, which has a negative value. To generate a signal at the network output, the activation function of a single jump is applied. A VHDL model of neural network is developed, consisting of an adder of the input signal elements and subtractor vector, discharge grid output signal of which is the output signal of the network. The model of an adder of the input signals vector is designed in VHDL. The modeling of recognition of various states of chicken embryos is performed. When perform the ovoscoping, the light sector of the egg area corresponds to a signal equal to 0, and the dark sector to signal 1. Total, the state of 6 sectors of area of the poultry egg in the model is analyzed. During the simulation, when a live embryo is fixed, the signal at the output of the network is 1, and when a dead egg is detected, this signal is 0. Verification of the VHDL model against test sets is confirmed the diagnostic properties of the ANN model. By including artificial intelligence in the FH vision system, visual control of the chicken embryos development is automated using an autonomous, easily integrated solution, as opposed to executing solutions that require special programming tools and runtime environments. This vision system also does not require artificial intelligence expertise to set up in poultry farms.
