Embedded water quality field analyzer based on neural network

Taking a water quality field analyzer as an example, a solution is proposed based on embedded and neural network. The hardware and the software design are introduced in detail. Then we sum up the complex nonlinear relation between the evaluation standard and the evaluation results through the continual study and training of BP neural network, and finally establish the BP neural network model. The system has wide application prospect with the advantages of small volume, low cost, high reliability, etc.
