That is, the loop cable 200 can function as a power supply and a signal transmission at one time. However, the present invention is not limited thereto, and the power supply cable and the signal transmission cable may be separated from each other.

The wireless transmit / receive module 300 may be located on a loop formed by the loop cable 200. The wireless transmission / reception module 300 may be electrically connected to the loop cable 200. The wireless transceiver module 300 may communicate wirelessly with the wireless charging fire detector 400.

Accordingly, the wireless transmission / reception module 300 can receive a fire detection signal from the wireless charging fire detector 400. [ The wireless transmission / reception module 300 may transmit the fire detection signal to the loop cable 200. The fire detection signal transmitted by the wireless transmission / reception module 300 may be transmitted to the main control panel 100 through the loop cable 200.

The wireless transmission / reception module 300 may wirelessly transmit power transmitted from the main control panel 100 through the loop cable 200 to the wireless charging fire detector 400. The wireless transmission / reception module 300 can transmit power at a high frequency according to a certain frequency by a magnetic resonance method.

The wireless transmission / reception module 300 may be plural. When the wireless transmission / reception module 300 is connected to the loop cable 200, its position is not limited. However, the wireless transmission / reception module 300 may be one or two for each deck of the ship. Because one or two per deck can cover a greater number of wireless charging fire detectors 400.

The wireless charging fire detector 400 may be in non-contact with the main control panel 100, the loop cable 200, and the wireless transmission / reception module 300. The wireless charging fire detector 400 can communicate wirelessly with the wireless transmission / reception module 300.

The wireless transmission power cable 210 may be connected to the transmission coil 320 in the wireless transmission / reception module 300.

The signal transmission cable 220 may transmit a fire detection signal transmitted from the wireless charging fire detector 400. [ Specifically, the signal transmission cable 220 can be used to transmit the fire detection signal wirelessly transmitted from the wireless charging fire detector 400 to the main control panel 100 by the wireless transmission / reception module 300.

[ The short range wireless communication module 310 may transmit the fire detection signal to the main control panel 100 through the loop cable 200. [ Specifically, the short range wireless communication module 310 may be connected to the signal transmission cable 220. Also, the short-range wireless communication module 310 may be connected to the communication cable 230.

The transmission coil 320 can convert the power transmitted by the loop cable 200 into a high frequency of a preset frequency. The high frequency may have a frequency in MHz. For example, the high frequency may range from about 1 MHz to 20 MHz. However, the present invention is not limited thereto. The effect of magnetic resonance can be maximized when the frequency range of the high frequency is in the unit of MHz.

When transmit coil 320 transmits power, receive coil 432 can receive it. At this time, the principle of transmitting and receiving electric power can be based on a magnetic resonance method. The magnetic resonance method refers to a phenomenon in which an electron or a nuclear spin system in an atom having a magnetic moment absorbs energy at a specific frequency, that is, a resonance frequency, when an external alternating magnetic field is applied. That is, the transmission coil 320 and the reception coil 432 are designed to resonate at the same frequency, and power can be transmitted and received to each other.

The base 410 may form the body of the wireless charging fire detector 400. That is, the transmitter 420, the sensing unit 450, the attachment unit 440, and the power source unit 430 are all connected to the base 410 or installed in the base 410 . The sensing unit 450 may be coupled to the base 410 and the transmission unit 420, the power unit 430 and the attachment unit 440 may be installed on the base 410. However, the present invention is not limited thereto.

The base 410 may be in the shape of a disk having a constant thickness as shown in FIG. However, the present invention is not limited to this, and any shape can be made as long as it can be easily installed on the wall surface. The base 410 may include a first surface and a second surface. A power supply unit 430, a sensing unit 450, and a transmission unit 420 may be coupled to the first surface of the base 410 in a rod shape. An attachment portion 440 may be provided on the second surface of the base 410. The second surface may be flat to attach to the wall surface. However, the present invention is not limited thereto.

The sensing unit 450 may be coupled to the base 410. The sensing unit 450 may sense a fire. The sensing unit 450 may detect a fire and generate a fire detection signal. The sensing unit 450 may transmit the fire detection signal to the transmitter 420. [ The sensing unit 450 may be configured to sense at least one of the heat of the fire and the smoke by exposing the sensor to the outside. The sensing unit 450 can be easily separated from the base 410 so that the sensing unit 450 can be periodically replaced. The sensing unit 450 may be formed to be exposed to a bar shape provided on the base 410. [ However, the present invention is not limited thereto, and this is merely an exemplary shape.

The transmitting unit 420 may be installed in the base 410. The transmitting unit 420 may receive the fire detection signal generated by the sensing unit 450. The transmission unit 420 may transmit the fire detection signal to the wireless transmission / reception module 300. The transmission unit 420 may wirelessly communicate with the short-range wireless communication module 310 in the wireless transmission / reception module 300. The transmitter 420 may perform wireless communication in the same manner as the short-range wireless communication module 310. That is, the transmitting unit 420 may use at least one short-range wireless communication method such as Bluetooth, NFC, and RF communication method, as with the short-range wireless communication module 310. [ Also, the present invention is not limited to this, and may be an access point (AP) as a relay point of wireless communication. The AP may use WiFi or the like. However, the present invention is not limited thereto.

The transmitter 420 may be formed at one end of the rod, as shown. However, this is merely exemplary and not limiting.

The receiving coil 432 can receive the high frequency transmitted by the transmitting coil 320. [ The receiving coil 432 may be magnetically resonated by the high frequency transmitted by the transmitting coil 320. [ The frequency of the high frequency may be set in advance, as described above, and may be in the unit of MHz. However, the present invention is not limited thereto.

The rectifier 436 can rectify the high frequency wave received by the receiving coil 432, that is, the alternating current signal, into a direct current. That is, the rectifier 436 can generate a direct current, which is the power used by the base 410 or the battery 434. The process of rectifying by the rectifier 436 may be necessary because the wireless power transmission can not be transmitted in the form of a direct current and must be transmitted in the form of an electromagnetic wave.

The battery 434 may store the direct current generated by the rectifier 436. The battery 434 may store power and provide power to the base 410 at a later time. Specifically, the battery 434 can supply power to a portion requiring power such as the sensing unit 450 and the transmission unit 420.

The attachment portion 440 may attach the base 410 of the wireless charging fire detector 400 to the hull such as a wall surface. The wireless rechargeable fire detector 400 can be positioned anywhere freely because there is no need to connect wires because signal transmission and power supply are wireless. Therefore, the attaching portion 440 can attach the wirelessly-charged fire detector 400 to any surface of the wall such as a floor, a ceiling surface, and a sidewall surface.

The attachment portion 440 may be a magnetic body. Since the hull of the ship is generally made of metal, the wireless charging fire detector 400 can be freely attached to a desired wall surface by using a magnetic body. In addition, when the attachment portion 440 is a magnetic body, attachment and detachment are free, and rearrangement can be facilitated. However, the present invention is not limited thereto.

The attachment portion 440 may be formed on the lower surface of the base 410. However, the present invention is not limited thereto. The attachment portion 440 may be installed on the opposite side of the sensing portion 450 to allow the sensing portion 450 to easily detect a fire. However, the present invention is not limited thereto.

Unlike the existing wired equipment, the wireless charging fire detector 400 according to the embodiment of the present invention makes all communication and power supply wired, so that there is no restriction on the installation of the cable. It is easy to arrange them at positions, and it is also easy to rearrange them.

In addition, it is easy to replace the sensing part 450, which is easy to break, and it is not necessary to fix the position of the fire alarm in advance at the time of designing the hull, so that efficient fire monitoring and design cost reduction can be effected.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
