Abstract

Based on mass production, cost saving and other commercial ideas, the temperature detection module in solar water heaters usually use inexpensive temperature sensors with low sensitivity and accuracy, the design in the hardware conditions are not ideal conditions, in order to make the temperature detection error to meet the design requirements, the design needs temperature detection range of -10 to 100, the temperature detection error range required to control ± 1, now the Multiple temperature detection methods are compared and studied to come up with a temperature detection method with high stability and low error to meet the design requirements. In this paper, the three methods of fitting, interpolation and table look-up method are compared and analyzed under the condition that the hardware accuracy is not high, and MATLAB software is used to conduct simulation experiments to verify whether the error meets the design requirements, and data are collected in reality to verify whether the accuracy meets the error requirements. The experimental results show that the look-up table method is based on the schematic diagram to get the relationship between the ADC sampling value and the temperature value, with the advantage that environmental errors can be ignored, etc., can better meet the requirements of the accuracy of the solar water heater temperature measurement error, and the performance is more stable and reliable.
