Abstract
Due to construction projects testing requirements work continuously for more than a week or even a month or so, so for a battery-powered portable heat and temperature acquisition system, its power consumption has the constraints. In accordance with the need of the acquisition system of actual engineering, this paper from two aspects of hardware and software to consider heat flux and temperature acquisition system of low power design, specific design ideas and implementation methods is also given in this paper. The test results demonstrate that the sleep state, the actual operating current is 0.59mA. A nominal 1000mAh lithium battery, the case of the sleep wake of five minutes, can work continuously for about 20 days, the case of 10 minutes to wake up dormant, can work continuously for about a month.
