| Abstract: | This paper has introduced the importance of temperature monitoring and its application in hydropower station. The multi-point temperature survey monitoring device which is applied presently in the small and medium size hydropower stations in China. A new temperature survey monitoring system which is based on DS18B20 sensor and 89C51 CPU chip has been designed. The system adopts 1-Wire sensor net technique. Many sensors are connected to 1-Wire bus as intelligent terminals. It has greatly simplified the hardware of multi-point temperature monitoring systems, as well as its design theory and extremely wiring method. Moreover, it has effectively increased the precision and resolving power of temperature monitoring. |
