Key technology of distributed temperature field monitoring system based on single bus

Abstract

Abstract In the artificial stratum freezing method construction, the stratum temperature is an important basis for judging the thickness, strength and stability of the frozen wall. The temperature of the circulating return brine is an important indicator reflecting the state of heat exchange between low-temperature brine and the stratum. Due to the large number of temperature measurement points, long measurement distances, and relatively scattered positions in the freezing project, this paper uses a single-bus temperature measurement technology to develop a monitoring system based on high-performance microcontrollers and distributed digital temperature measurement cables on the hardware. Combined with LabVIEW software, the real-time collection and monitoring of temperature data is realized.
