In addition, the processor may read the computer program stored in the memory to control the crack detection monitoring apparatus 100 to detect a crack according to an embodiment of the present disclosure and transmit a signal.

In addition, the processor may transmit a signal to the outside at a preset time (eg, 10 minutes) using a real-time clock. Since the processor transmits the signal only for a preset time, it is possible to use less power of the power supply unit.

The memory may store any form of information generated or determined by the processor. Here, the memory is a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (eg SD or XD memory, etc.), RAM (Random Access Memory, RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory, ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic It may include at least one type of storage medium among a disk and an optical disk. The description of the above-described memory is only an example, and the present disclosure is not limited thereto.

The communication unit 180 may transmit a signal processed by the central processing unit 170 to an external device. Here, the communication unit 180 may be configured regardless of its communication mode, such as wired and wireless, and may be configured with various communication networks such as a short-range network (PAN: Personal Area Network) and a local area network (WAN: Wide Area Network). there is. In addition, the communication unit 180 may be a known World Wide Web (WWW), infrared (IrDA: Infrared Data Association) or a wireless transmission technology used for short-range communication such as Bluetooth (Bluetooth) may be used. . Also, the communication unit 180 may include any wired/wireless communication network capable of transmitting and receiving any type of data and signals.

The power supply unit 190 includes a power supply (eg, battery, dry cell), can supply power to the central processing unit 170 through the power supply, and supplies power only when the central processing unit 170 operates. Power consumption can be reduced by supplying power and entering a sleep state when not in operation.

The various embodiments presented herein may be implemented as methods, apparatus, or articles of manufacture using standard programming and/or engineering techniques. The term article of manufacture includes a computer program, carrier, or media accessible from any computer-readable storage device. For example, computer-readable storage media include magnetic storage devices (eg, hard disks, floppy disks, magnetic strips, etc.), optical disks (eg, CDs, DVDs, etc.), smart cards, and flash drives. memory devices (eg, EEPROMs, cards, sticks, key drives, etc.). Also, various storage media presented herein include one or more devices and/or other machine-readable media for storing information.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Thus, the present disclosure is not intended to be limited to the embodiments presented herein, but is to be construed in the widest scope consistent with the principles and novel features presented herein.

As described above, the relevant contents have been described in the best mode for carrying out the invention.

The present disclosure may be used in a crack detection monitoring system.
