Device for preventing loss of objects and method for preventing loss of objects using the same

摘要

According to one aspect of the present invention, a method for preventing loss of an object using a master module and one or more slave modules capable of communicating with the master module is provided. According to an embodiment of the present invention, the calculation unit built in the master module is lost when the result of processing exercise information received from the master module and the slave module satisfies all of the first to third criteria set in advance. An alarm is generated and transmitted to a warning unit built in at least one of the master module and the slave module. Determining whether the first and second criteria are satisfied includes comparing information including acceleration values of the master module and the one or more slave modules with first and second reference values, and the third Determining whether the criteria are satisfied includes comparing the three-axis acceleration or angular velocity signal patterns of the master module and the one or more slave modules with each other.
