Environmental Parameters Monitoring System Is Developed

Detecting and controlling the environment's parameter is an important task in practical industrial manufacture process. Obtaining these parameter correctly can help us to gain the instrument's state. And that we can use some theory to fix the error caused by the temperature and the humidity. It can improve the instrument's performance.For this aim, we designed a multi-thermometer and hygrometer synthesized system. In this project, we use this system to measure the FOG's(Fiber-Optical gyro) surroundings temperature and humidity. This paper first analyzed some kinds of method about testing the temperature and the humidity. Then balance the different method's disadvantages, advantages, and the using system's meterage requirement about the precision, testing rate, and so on. And then choosing the digital thermometer 18B20, and digital hygrometer SHT11 as the system's sensors. And set the TI's MCU, MSC1211, as main processor. Based on this work, designed a hardware circuit. This circuit can achieve the testing function. We use the temperature chest to demarcate the system.The experiment result shows that this system can touch the target that present in the design requirement. At the last of the paper, we use this system to get the FOG's environment temperature and fix the excursion that caused by temperature. The result shows that this multi-thermometer and hygrometer synthesized system can weaken the FOG's temperature sensitive.
