Geothermal Parameters Test System Based on ARM S3C2440

Abstract:

A test system for geothermal parameters is designed with S3C2440, it is an embedded system which can friendly display the test values and geothermal parameters in real time. The test theory is based on heat balance principle. A heater produce heat to induce into the ground through U buried tube. When equilibrated, the heat from the heater is equal to the heat taken away by ground. The heat taken away by ground is measured by testing the temperatures of two ends of U buried tube and the water velocity flowing through tube; the real produced heat by heater is measured by testing the current and voltage of heater. The heat power can be changed by controlling solid-state relay with PWM. The driver programs in S3C2440 for the testing sensor of temperature, current, voltage, water flow and PWM are designed with Linux; the testing values are real displayed and can be saved which interface is designed with OSS QT4.
