According to the vertical multi-point temperature measuring device, a large-scale temperature field measurement system is adopted. The vertical multi-point temperature measuring device is widely applied to fields such as the water conservancy, hydrology, ocean and environment field flow monitoring fields. The vertical multi-point temperature measuring device is characterized in that a vertical high-density armored thermal resistor core array is constructed; the characteristics of high measurement accuracy and short reaction time of armored thermal resistor cores are utilized, and therefore, high-accuracy measurement data can be acquired in a test process; conversion and transmission of test data can be realized quickly through the Fieldbus foundation, and therefore, quick and high-precision measurement of a vertical temperature filed can be realized. With the vertical multi-point temperature measuring device of the utility model adopted, measurement accuracy of water temperature at each position in a water body can be improved. According to the vertical multi-point temperature measuring device, one bus is adopted to acquire data and transmit the data to a computer, and therefore, wiring complexity can be simplified, and the stability and reliability of a system can be improved.
