The invention discloses an earplug arrival reminding system and a control method thereof. Based on general parts such as an earplug body, a connection wire and a mobile terminal, the earplug arrival reminding system also comprises a position sensing module, a voice alarm module, a communication interface module, an MCU module and a fixed value configuration module. The longitude-latitude parameters of the reminding station are set through the fixed value configuration module and transmitted to the MCU module through the communication interface module and then stored as fixed values. The earplug runs independently; the MCU module constantly receives the real-time longitude-latitude data from the position sensing module and compares the longitude-latitude data with the fixed values; and if the absolute difference between the real-time longitude-latitude data from the position sensing module and the fixed values is less than 200m, the MCU module drives the voice alarm module to act. Through the system, a user is relieved to take a nap when taking a city bus or high-speed rail while the trouble of passing the destination can be avoided, so that the system has a particular application value to office workers and students going out early.
