In addition, the invention is provided with a GPS positioning unit, and when sending distress signals to other people, the invention sends the current accident position information to the person seeking help together, thereby facilitating the person seeking help to quickly determine the specific position and striving for rescue time as much as possible for rescue work. In addition, the communication unit is triggered to send the distress signal to the mobile terminal through the double insurance of the pressure detection unit and the temperature and humidity sensor, so that the intelligent helmet can timely ask for help outwards when an accident is sent.
