this article is to use AT89C51 single-chip microcomputer control of intelligent speed measuring instrument. Motor in the process of operation, need to be monitored, speed is a necessary one parameter. This system is carried out on the motor speed measurement, and can be conducted and PC communication, shows that the speed of the motor, and observe the basic condition of the motor running. Mainly USES AT89C51 as the control core, by hall sensors, LED digital tube, the NE555, L298N, operational amplifiers, etc. SCM measuring speed system was introduced in detail. Give full play to the performance of the single chip microcomputer. The focus is on measuring speed and display. Its advantage is hardware circuit is simple, software function is perfect, measuring speed, high precision, reliable control system, the characteristics of high performance-to-price ratio.

Stepper Motor Control

The NC Teaching Plotter is designed for the practice teaching needs of NC machining, In order to improve current existing practice teaching environment of "many student, less equipment". It explains the NC concept with concise way and demonstrates NC thought by the intuitive operation.In this paper, the design of NC teaching plotter makes interpolation motion between pen and table based on NC program in accordance with the requirement made by user, to draw the graphics by moving the magnet control brush painting through the single chip digital control and the two stepper motor control X, Y two axes feed. The NC teaching plotter which demonstrates more clearly and directly the numerical control idea has high practical value for teaching practice.
