The invention discloses an equipment control method. The method comprises steps that when a present control mode of field equipment is a remote mode, field equipment is controlled by DCS equipment through hard wiring in a remote mode; when the present control mode of the field equipment is a local mode, the field equipment is locally controlled by an ACC control cabinet through hard wiring. Through the control method, remote control on the field equipment is carried out through the DCS equipment, the DCS equipment is connected with the field equipment in a hard wiring mode, the severe field environment can be effectively dealt with, and reliability is relatively good. The control method is advantaged in that influence of the field environment factors on control equipment can be avoided. The invention further discloses an equipment control system, control equipment and a computer readable storage medium, and the advantages can be further realized.
