Filtering equipment control system and method

The invention discloses a filtering equipment control system and method, and belongs to the field of oil and gas transportation. The system comprises first control equipment and filtering equipment, and a controller obtains component state information and pressure difference values of a plurality of filtering branches; the first control device is used for sending a filter branch switching instruction to the controller in response to the component state information or the pressure difference value meeting the in-use filter branch abnormal condition if the filter device is in the one-use one-standby mode, and sending the filter branch switching instruction to the controller if the filter device is in the multi-use multi-standby mode. In response to the condition that the component state information or the pressure difference value meets the abnormal condition of the in-use filter branch, sending a filter branch opening increasing instruction to the controller; the controller receives the filtering branch switch
