This design project for graduation’ task is to monitor intellectual tachometer measurement device electrical machinery when it runs, Tachometer is an indispensable parament. And then this system can solve the problem of monitoring tachometer by tachometer, and it can achieve the communication of the machine of PC.
For adjusting the stability of the electrical machinery when it runs, take notes the record about the tachometer per minutes; draw the coordinate charter between tachometer and time.
This design mainly applies AT89c51 to control core and combine sensor, LED, HIN232CPE, and RS232.this design introduce the system of tachometer measurement of MCU.
The send and receiver of the date take the full use of the natural capacity of MCU. The key of this paper is to measure tachometer and manifest it on LED.
The advantages are simple hardware electrical circuit, perfect software competence, high-speed measurement, high accuracy, reliable control system, relatively high price and other features
