BLUETOOTH SIGNAL DETECT/ALARM APPARATUS

摘要

PURPOSE: A Bluetooth signal detect/alarm apparatus is provided to use a Bluetooth module for transmitting/receiving a signal matching the Bluetooth standard, thereby capable of developing a device preventing from missing simply. CONSTITUTION: The portable Bluetooth terminal module(10) includes a portable Bluetooth module(19). The portable Bluetooth module(19) transmits and receives a signal according to the Bluetooth standard to a central terminal supervising module(20). A portable microcomputer unit(18) processes the signal from the portable Bluetooth module(19). A portable output unit(11) outputs the processed signal to the outside. The central terminal supervising module(20) includes a central Bluetooth module(29). The central Bluetooth module(29) transmits and receives a signal according to the Bluetooth standard to the portable terminal module(10). A central microcomputer unit(28) processes the signal from the central Bluetooth module(29), simultaneously detects a distance between the portable terminal module(10) and central terminal supervising module(20) and outputs an alarm signal when the detected distance is above than the predetermined distance. A key manipulating unit(27) is connected to the central microcomputer unit(28) and inputs a command for transmitting a specific signal to the portable terminal module(10). An output unit(21) outputs the processed signal and the alarm in order to be recognized by the users.
