Condition monitoring and mistake precaution system for power strap based on photoelectric detection

Thermal environment is analyzed based on the field measurements of indoor and outdoor temperature and humidity of a typical Tibetan traditional dwelling in a village of Gannan Tibetan Autonomous Prefecture, Gansu province in winter and summer. Results show that the combination of local factors such as history, geography, climate, unique local-style dwelling houses building structure and monomer structure. The structure (envelope)of traditional Tibetan dwelling has a good thermal performance. Passive methods should be used to build thermal environment constructions. Further improvement for indoor thermal comfort conditions through comprehensive and energy-saving heating are needed.
