The utility model discloses a rail side acoustic emission sensor fixing pressure control system with a self-adjusting function, and relates to a steel rail sensor fixing system. Comprising an electric push rod device, a force measurement detection system, a comparison control system, a switching control device and a rail side base, the electric push rod device is used for applying pressure to an acoustic emission sensor, a pressure sensor of the force measurement detection system is located between a push rod of the electric push rod device and a mounting groove, and the force measurement detection system is connected with the comparison control system; the fixed pressure applied to the acoustic emission sensor is measured in real time, and the comparison control system is connected with the switching control device and used for comparing a set value with the push rod pressure and outputting a comparison result voltage signal, so that a push rod in the electric push rod device is controlled to move to adjust
