The S1 pressure anomaly signal feedback specifically includes the following steps: ​ S11, the contact diaphragm pressure transmitter data is transmitted to the data acquisition system, and a neural network training set and a test set are generated, the neural network comprising: an input layer containing four neurons, respectively representing the output pressure of the pressure sensor, the filling pipeline temperature, the filling pipeline humidity and the filling pipeline electromagnetic radiation, a hidden layer being set to a single layer of five neurons, and an output layer being one neuron, representing the compensated pressure sensor output value; S12, randomly generate initial weights and thresholds of the neural network, encode them and divide them into different populations; S13, local convergence is performed within the population, global differentiation is performed between the populations, and the optimal individual is searched within the global range; S14, the initial weights and thresholds of the optimal individual are obtained and the mean square error is calculated; S15, the compensated pressure sensor output value is obtained by adjusting the weights and thresholds; S16, the compensated pressure sensor output value is transmitted to the data acquisition system as the pressure monitoring valve value, and the coarse aggregate paste filling pipeline pressure monitoring and pipe blockage early warning are completed.
