  1. The traditional level measuring methods can n ' t meet our demand because the subjective investigated is in such a poor systemic condition that the temperature is a little high and there ' s so many mill dust and steam there. in this article we perform systemic discuss and research against the dynamic level measuring method under special working condition on the basis of analyzing kinds of level measuring technique in and abroad. first we establish the pressure distribution mathematic model in storage bin and then deduce the mathematic relation between level height and the uniform stress on the bottom of the bin and designed a resistance compressive stress sensor used for the special condition and put forward a resoivement according to its zero excursion existing in practical use

    由於本研究系統被測對象環境溫度較高且潮濕，同時料倉中有大量粉塵及蒸汽，因此傳統的料位檢測方法不能滿足本測試要求。本文在分析國內外各種物位檢測技術的基礎上，針對特殊工況下動態物料高度的檢測進行了系統的探討與研究。首先建立了料倉中的壓力分佈數學模型，推導出料位高度與倉底均布壓力間的數學關系式，並據此設計了中溫電阻應變式壓力傳感器，同時對它在實際應用中存在的零點漂移等問題提出了改進措施，提高了傳感器性能，解決了上述特殊工況下動態物料檢測的技術難題。
  2. By use plc, system can complete function as follow : this auto - control system be applicable to the temperature and smoke and dust the deal the variety quick, control the process is difficult with the operation is ; by the temperature controlor can automatically follow to the wet tower " exit temperature, error in the ? 3 v including ; by to automatically spray fog to lower the electric resistance, with the function for full the electricity equipment accepting the dust ; because of adopting feedback closed loop, and come to a to respond to the speed quick, constant temprature control the accuracy is high ; because of adopting the sensors, and make the system circumstance to leak water quick ; system have many control parameter can set exit control temperature and adjust value low limit by key ; can communication with remote computer and have remote control

    通過使用plc ，使該自控系統可以完成如下功能：適用於溫度及煙塵量變化快、控制過程難以操作的場合；通過溫控表自動跟蹤增濕塔出口溫度，誤差達到3以內；通過自動噴霧來降低粉塵比電阻，以此充分發揮電收塵器的作用；由於採取了閉環反饋迴路，達到了響應速度快，恆溫控制精度高；通過使用各種檢測傳感器，使得異常情況泄水快；該自控系統具有多套控制參數，增濕塔出口控制溫度及調節閥下限值可通過按鍵設定；可與上位機通訊，具有「現控遠控」功能。
