Abstract
The invention relates to a buffer controlled by a processor module. During buffering work, the right end face of a cylinder of a last-stage buffer body serves as the contact face of the collision of the cylinder and a sliding block. An electromagnetic coil is wound in the side wall of the cylinder of the last-stage buffer body. A pressure sensor for detecting the pressure of a medium is arranged on the right end face of a piston assembly of the last-stage buffer body, and is connected with the processor module. When the sliding block collides with the right end face of the cylinder, the processor module is suitable for controlling a current driving module to output current matching the pressure value of the medium according to the pressure value of the medium, so that the electromagnetic coil generates a corresponding magnetic field to attract the sliding block. When the piston assemblies of all buffer bodies do piston motion, a processor is suitable for regulating or closing the back-forth flow of the medium in the corresponding cylinders according to the pressure, detected by the pressure sensor, of the medium to control the motion speed or buffering level of the piston assemblies.
