摘要：
Aiming at the demand of multi-channel temperature measurement, a multi-channel temperature measurement system was developed based on field programmable gate array (FPGA) and low power core (STM32). The FPGA chip is the main controller of the system, which directly drives the multiple analog to digital converter chips to measure the multi-channel electric signals synchronously. The STM32 was used to perform the conversion and calculation of the temperature signal. The accuracy of the temperature measurements is expected to be within 0.01℃ in the temperature range from -200 to 850℃. The system was validated in the temperature range from -200 to 850℃. The experimental results showed that the accuracy is less than 0.003℃ in the temperature range from -200 to 400℃, and less than 0.005℃ at temperatures up to 850℃. The system has high measuring accuracy, can be used in multi-channel synchronous measurement, and is easy to expand the number of channels. © 2017, Editorial Office of Journal of Xi'an Jiaotong University.
