地下工程环境大气腐蚀监测系统设计

DESIGN OF ATMOSPHERE CORROSION MONITORING SYSTEM FOR UNDERGROUND ENGINEERING

根据腐蚀电化学原理，应用微机技术对地下工程环境大气的腐蚀性、温度、湿度、ｐＨ 值进行监测，其测试单元具有高灵敏度、自动选择量程、自动测量等功能，控制主机通过与各测试单元进行数据通讯，控制各测试单元进行周期及随机测量，接收、贮存、处理并显示各测试点数据，并可通过扩展串口与ＰＣ机进行数据通讯，接受其控制．

According to the principles of corrosion electrochemistry, an atmosphere corrosion monitoring system has been designed with microprocessor to monitor the corrosion rate, temperature, relative humidity and pH value for underground engineering. Its measuring unit is highly sensitive, it can automatically select suitable scale and continuously measures the data. In communication with each slave, its master can control each slave to measure in cycle or at random, and it can also receive, store, process and display the data from the units. It can transfer the measured data to personal computer for further processing and receive PC's control. The system is useful to monitor the atmosphere corrosion environment in underground engineering.
