After an on-site investigation and subsequent analysis of a derailling incident of a bridge type reclaimer, a sychrocontrol method based on dynamic zero resetting was proposed as the solution; the pertaining control system was designed and the relevant functional tests performed.

This paper presents the design proposal of an floating-point including its working principle,and discusses the cycle amplification and the automatic zero adjustment algorithm.

Study on automatic zeroing of capacitive accelerometer;

Taken the state monitoring system for forging machinery during producing process as example,the influence factor is studied for the drift rate of the automatic zero circuit.
