A Real-Time Evaluation Method on Internet Data Centre's Equipment Corrosion by Wireless Sensor Networks

摘要

With the implementation of European Union's restriction of hazardous substances directive, there is a sharp decline on electronic equipment corrosion resistance. The reason is that gaseous contaminations cause creep corrosion on printed circuit boards. Based on wireless sensor networks, three-dimensional space model, environmental information and computational fluid dynamics theory, an evaluation method is proposed to calculate the wind speed, temperature, relative humidity and corrosive gas concentration around each equipment in internet data centre. To evaluate the performance of this method, a wireless sensors system is set up. Test results show that the real-time evaluation method can effectively guarantee equipment in safe environment.
