The invention discloses a
system and a method for detecting
mobile phone cardiac sound based on an earphone interface. The detection
system comprises a cardiac sound
signal acquiring and
processing module for acquiring the cardiac sound
signal of a user, a
Java mobile
information device profile (JavaMIDP) protocol supporting
mobile phone and a
community center
server. In the detection method, a cardiac sound
signal is acquired through a cardiac sound sensor; the signal is transmitted to the
mobile phone through the earphone interface; a dynamic cardiac sound oscillogram is displayed through the mobile phone; at the same time, the user can upload the cardiac sound data of the user to the
community center
server through the mobile phone; the
community center
server receives the data transmitted by the mobile phone in real time through a WEB and compares the cardiac sound data with standard cardiac sound data at the same time; and when the user sends a request for viewing a result through the mobile phone, the
community center server automatically responds and feeds back a detection result to the mobile phone of the user. The detection
system is easy and convenient to operate and high in real-time property and mobility, and the user can perform cardiac
sound detection in the home of the user or in other places conveniently.
