Pressure bearing detection method, device, control cabinet and system of base meter

The invention relates to a base meter pressure bearing detection method, device, control cabinet and system. The method comprises the steps of receiving a pressure setting demand, obtaining model information of a to-be-tested base meter, determining a pressure-bearing use demand according to the model information, and obtaining test input parameters according to the pressure-bearing use demand and the pressure setting demand. And obtaining the detection capacity of the pressure-bearing detection chamber, determining the model of the sealing gasket and the displacement of the upper sealing clamp according to the model information and the detection capacity, and determining the movement amount of the oil cylinder and the expansion amount of the piston rod of the oil cylinder according to the displacement. The upper sealing clamp is controlled to be replaced to a corresponding sealing gasket, the oil cylinder is controlled to move by a corresponding movement amount, the piston rod of the oil cylinder is controll
