| description | The invention discloses a high-precision sea ice temperature chain, and belongs to the technical field of the polar region monitoring. The temperature chain is composed of a host machine and multipleslaves; the host machine is used for reading the data of the whole temperature chain and performing data interaction with the external; the slaves are used for collecting and uploading the temperaturedata; and the host machine and the slaves adopt the RS485 bus communication way. Each single-point platinum resistor temperature measurement unit adopts the software correction, the single-point temperature measurement error is at most 0.0069 DEG C. The temperature chain can be used for simultaneously measuring the temperature at multiple points under the low-temperature environment, and the entire reliability is high; the temperature chain is suitable for performing vertical section detection on a temperature field of glacier and the sea ice under the polar environment, and can be used for the soil environment temper |
