Abstract: The present invention discloses an automatic bio-signal supervising system for medical care. The automatic bio-signal supervising system utilizes a head-mounted bio-signal acquisition device, wore upon the user's head, to acquire the bio-signals, convert them into the digital bio-signals, and transmit the digital bio-signals to a signal analysis processor to perform analysis process. And the automatic bio-signal supervising system delivers a corresponding control signal to the environment control equipment based on the result of analysis, and control the environment condition to achieve the remote supervising and medical care purpose. Furthermore, the signal analysis processor in the present invention further provides a real-time warning signal or a health index, which supervise the personal biological information to avoid the unpredictable situation.
