          摘 要
          本課題研究的內容主要是利用電磁感應原理對各種液體如石油、水等的流量進行檢測與控制。主要由流量傳感器采集流量信號,然后經過A/D轉換器將連續的模擬信號轉化為離散信號后傳給單片機運算,單片機在軟件系統的控制下,根據預先的設置和預期的控制要求,將控制命令發送到步進電機,然后通過步進電機來精確控制閥門的開關,實現對流量的精確控制,并通過顯示單元實時顯示。在設計過程中,從總體方案、單元電路、元器件選擇和設計等都進行了細致的介紹。

          The content of this research is mainly using the electromagic induction principle to all kinds of liquid such as oil, water flow test and control. Mainly by flow sensor to collect traffic signal, and then, after A/D converter will be continuous analog signal into A discrete signal to the single chip microputer after operation, under the control of single-chip microputer in the software system, according to the control requirements of setting and expected in advance, will control mands sent to the stepper motor, and then through the stepper motor to precisely control the switch of the valve, realize the precise control of traffic, and through the display unit in real time. In the design process, from the overall plan, the unit circuit, ponents selection and design and so on all has carried on the
