Abstract: The present disclosure relates to a personal safety assurance system and a safety monitoring method. A smart band includes a detection module, a main chip, a band emergency button, and a wireless band connection module. The smart band transmits detected heart rate, blood pressure, and pulse of a human body to a safety monitoring application (APP). The band emergency button is configured to receive first emergency alarm information, and transmit the first emergency alarm information to the main chip. The main chip is further configured to transmit the first emergency alarm information to the safety monitoring APP through the wireless band connection module. The safety monitoring APP is configured to display the heart rate, the blood pressure, and the pulse, transmit a physical abnormality alarm signal to a hospital alarm platform, and transmit the first emergency alarm information to a public security alarm platform.
