Dosing control method and device, terminal equipment and storage medium

The embodiment of the invention is suitable for the technical field of mineral separation, and provides a chemical adding control method and device, terminal equipment and a storage medium. The method comprises the steps that the target chemical adding dosage needed by a chemical adding point is determined; determining the residual medicament amount in the metering tank; if the target chemical adding dosage is smaller than the residual chemical dosage, the opening frequency of a chemical adding valve is determined according to the valve flow of the chemical adding valve in the metering tank, the single opening duration of the chemical adding valve and the target chemical adding dosage; and controlling the dosing valve according to the opening times and the single opening duration so as to convey the medicament in the metering tank to the dosing point. By adopting the method, the dosing precision of the dosing point can be improved. 本申请实施例适用于选矿技术领域，提供了一种加药控制方法、装置、终端设备及存储介质，该方法包括：确定加药点所需的目标加药剂量；确定计量罐中的剩余药剂量；若目标
