Transmission mechanism early warning device and method

The invention discloses a transmission mechanism early warning device and method. The early warning device comprises a digital display pressure sensor, and the digital display pressure sensor communicates with a triple piece and an electromagnetic valve; the triple piece is communicated with the main air pipe, and the electromagnetic valve is communicated with an air cylinder of the transmission mechanism; the transmission mechanism comprises a main shaft which is connected with the output end of a piston rod of the cylinder; a bracket is arranged outside the main shaft; the proximity switch induction ring is fixedly arranged at the upper part of the main shaft; the upper proximity switch and the lower proximity switch are arranged on the upper portion and the lower portion of the inner side of the support respectively. According to the working method of the early warning device, early warning is achieved by detecting the operation time and the digital display pressure sensor. According to the transmission me
