The measurement and control system is designed to control the measuring instrument which measures the geometric parameters of rail fastening spring clips. The structure and work principle of the measurement and control system are presented. Nine geometric parameters of a rail fastening spring clip which is installed only one time can be measured atomically. The limited errors of measured parameters are largely smaller than one tenth of the geometric parameter tolerance. It only spends 40 seconds to measure a rail fastening spring clip. It improves the quality of the rail fastening spring clip production and ensures that it is safe and reliably used in railway.
