The invention provides a heart sound acquisition and analysis system and method based on a cloud framework. The system comprises a heart sound signal acquisition device, a wireless transmission module, an embedded terminal, a cloud platform and a heart sound analysis module. According to the heart sound acquisition and analysis system and the heart sound acquisition and analysis method, heart sound signals are acquired, subjected to analog-to-digital conversion, filtering, noise reduction and amplification processing and then transmitted to the embedded terminal in a wireless manner; the embedded terminal preliminarily classifies normal heart sound signals and abnormal heart sound signals through an algorithm, eliminates normal heart sound data, and uploads detected abnormal heart sound data to a cloud platform through the wireless transmission module for further analysis and diagnosis; the cloud platform acquires, displays, stores, analyzes and diagnoses the abnormal heart sound signals, and finally obtains a diagnosis result. By adopting the system and the method, environmental noise at the front end can be well restrained, the heart sound signals are intelligently analyzed and diagnosed on the cloud platform after the abnormal heart sound is extracted, and doctors and other professional medical workers are allowed to check the abnormal heart sound and give relevant diagnosisinformation.
