范文编号:ZD400 范文字数:19791,页数:60 Equipment of liquid droplet monitor controlled by microcontroller Abstract: The system is an automatic equipment basing on microcontroller AT89C51 to control the medical injecting efficiently. Adopting infrared sensor to check and measure the speed of liquid droplet and the high of the liquid’s surface in the droplet bottle. Using communication among microcontroller ,I adopt RS-485 as the way of communication to march the communication of sites to sites to design an automatic system of a major site controlling sixteen subordinate sites. The major site mainly controls the sixteen subordinate ones and gives alarm and shows the information that subordinate sites feedback. The subordinate sites mainly check the speed of liquid droplet and control the speed and also control whether the liquid surface achieves the cordon, moreover, can give alarm if there are abnormal phenomenon. I adopt the keyboard indicators circuit of 8279 chip to set and show the speed of droplet. I also use PM electrical machinery to regulate the speed of droplet. 目 录 摘要…………………………………………………………………………………………Ⅰ 单片机液体点滴速度监控装置设计相关范文 |
