Calculation method for target water adding amount during ingredient stirring and accurate water adding system

The invention relates to the technical field of brick making, and particularly discloses a method for calculating the target water adding amount during ingredient stirring, and the method comprises the steps: combining a water amount signal fed back by a flowmeter and the target water adding amount precisely calculated by a PLC according to a hygrograph; the calculation method of the target water adding amount comprises the following steps: S21, simulating a stirring period to calculate the non-calibration value change rate of each humidity increase; S22, calculating the water content of the mixture of the current batch according to the following formula; and S23, calculating the target water adding amount X = S * (G-M0)-M0 at one time according to the following formula. The PLC reads the current humidity in real time through the analog quantity, calculates the water content of the current material through a calculation formula, and adjusts the proportioned water adding amount in real time, so that the materi
