Based on AT89 series single-chip microcomputer, a type of portable testing device for elevator speed governor is presented which is mainly made up of power converting module and measuring-controlling module. The power converting module supplies working power for the testing device and the measuring-controlling module includes a driving motor and a single-chip micro-computer measuring-controlling system. The single-chip micro-computer controls the servo motor to drive the speed governor′s wheel. Through a Hall switch, the rotating speed of the wheel can be measured and the lift car′s moving speed can be calculated combined with the pitch circle diameter. The electrical acting speed and mechanical acting speed of the speed governor can be captured with the aid of an electrical switch and a mechanical limit switch. The components of the testing device are introduced , the working principle of the testing device is analyzed, and finally the prototype of the testing device is developed.
