1. A fracturing control apparatus, comprising a first chemical agent storage tank storing a first chemical agent, a first delivery pump, a fracturing pump, a first and a second flow detector, a first and a second fracturing fluid conveying pipeline, a centrifugal pump, and a controller, wherein:
the first chemical agent storage tank is connected with the first delivery pump;
a material outlet of the first delivery pump is connected with a first position of the first fracturing fluid conveying pipeline via the second flow detector;
the centrifugal pump is disposed at the first fracturing fluid conveying pipeline;
an outlet of the first fracturing fluid conveying pipeline is connected with an inlet of the fracturing pump;
an outlet of the fracturing pump is connected with an inlet of the second fracturing fluid conveying pipeline;
the first flow detector is arranged at a second position of the second fracturing fluid conveying pipeline;
the controller is configured to (i) receive a discharge amount value from the first flow detector and a value of a flow amount of the first chemical agent from the second flow detector, and (ii) when the discharge amount value and the value of the flow amount of the first chemical agent do not match a proportional relationship pre-stored in the controller, adjust a flow of the first chemical agent from the first chemical agent storage tank to the first fracturing fluid conveying pipeline according to the discharge amount value by sending a control instruction to the first delivery pump;
the first delivery pump is connected with a first output interface of the controller and is configured to pump the first chemical agent from the first chemical agent storage tank to the first fracturing fluid conveying pipeline based on the control instruction from the controller; and
the first fracturing fluid conveying pipeline is configured to transport fracturing fluids toward the first position, receive the first chemical agent from the first delivery pump at the first position, and transport a mix of the first chemical agent and the fracturing fluids to the fracturing pump from the first position to the fracturing pump.
