The invention discloses a switching control method of a multi-cylinder rotary compressor. The method comprises the steps that firstly, air pressure values and temperature values of a first air cylinder at a plurality of preset time points in a preset time period are arranged and subjected to correlation coding to obtain an air pressure-temperature correlation matrix of a second air cylinder; secondly, the air pressure values and the temperature values of the second air cylinder at the multiple preset time points are arranged and subjected to correlation coding, so that an air pressure-temperature correlation matrix of the second air cylinder is obtained; respectively processing the first cylinder air pressure-temperature correlation matrix and the second cylinder air pressure-temperature correlation matrix through a convolutional neural network model to obtain a first cylinder air pressure-temperature correlation characteristic matrix and a second cylinder air pressure-temperature correlation characteristic m
