The invention discloses an intelligent alarm bracelet for identifying a cry for help and an abnormal pulse, and an intelligent alarm method thereof. The intelligent alarm bracelet comprises a master control module, a cry-for-help identification module, an abnormal pulse identification module, a GPS positioning module, a short message and onsite sound transmission module, a fundamental frequency setting module and a pulse setting module. The invention further discloses an intelligent alarm method applied to an intelligent alarm bracelet for identifying a cry for help and an abnormal pulse. The method comprises the following steps: the cry-for-help identification module distinguishing the cry for help from other sounds; the abnormal pulse identification module compares wrist pulse frequency with set pulse frequency so as to determine whether the abnormal pulse occurs; the master control module, after receiving alarm signals the cry for help and the abnormal pulse, sending position and alarm text information to a preset mobile phone, calling the preset mobile phone, and transmitting an onsite sound to the opposite side after the call is answered; and the GPS positioning module obtaining position information. The intelligent alarm bracelet and the intelligent alarm method have the advantages of automatically identifying the cry for help and the abnormal pulse, automatically giving an alarm, sending the position information, transmitting the onsite sound and the like.
