Self-adaptive control method for fracturing fluid preparation based on powder-based system, terminal and storage medium

The invention provides a self-adaptive control method for fracturing fluid preparation based on a powder-based system. The self-adaptive control method comprises the following steps: constructing a fluid supply and preparation self-adaptive control system; dividing the liquid supply and preparation operation into a plurality of operation stages according to the liquid supply and preparation types, and establishing an operation stage library; inputting parameters of each operation stage into the operation stage library for one-to-one correspondence; based on the requirements of the operation stage library, corresponding names are set for the base liquid tank and the dry powder tank, and corresponding base liquid and dry powder are configured; on the basis of the total discharge amount of the mixing sledge, the current operation stage library is switched, the communication relation between the multiple sets of dry powder tanks and the mixing sledge is adjusted, and the communication relation between the mixing
