Optimization control method for differential pressure and flow at tail end of main pipe network

The invention relates to the related technical field of building construction, in particular to an optimal control method for the tail end pressure difference and flow of a main pipe network, and the optimal control method for the tail end pressure difference and flow of the main pipe network comprises the steps that the tail end pressure difference of the main pipe network is measured through a detection assembly, and the detection assembly comprises a detection assembly body, a rear connecting seat and a front connecting seat; the front connecting base is an annular plate, and the inner side face of the front connecting base is fixedly connected with the front side ends of the outer pipe wall, the middle pipe wall and the inner pipe wall. The detection assembly composed of the detection assembly body, the rear connecting seat and the front connecting seat is arranged, and the detection assembly body is composed of the outer pipe wall, the middle pipe wall, the inner pipe wall and the elastic layer, so that
