The controller 113 may connect to a first network connected to an internet network by connecting to an external access point. For example, the controller 113 may be connected to an access point such as a router and may be assigned an IP address corresponding to the address system of the first network.

The controller 113 generates a second network to which an external device can be connected through the access point unit 115, and upon receiving a connection request for the second network from the external device, sets a firewall for the second network. The external device may be connected to the second network.

For example, the controller 113 may be assigned an IP for the first network through a network interface card (NIC).

In addition, the external device may be assigned an IP address preset for the second network from the controller 113 Dynamic Host Configuration Protocol (DHCP) module.

The preset IP address is an IP address for an address system assigned to an external device connected to the access point unit 115, and the connected external device may access the second network through the assigned preset IP address.

For example, the controller 113 may connect to the second network through a virtual network interface card (VNIC), set a virtual network for the second network, and receive an IP. Thereafter, the controller 113 may change the IP address system of the second network to correspond to the IP address system of the first network.

In detail, the control unit 113 configures and implements functions such as a DHCP module, a network address translation (NAT) module, an IP masquerade, a virtual network interface card (VNIC), an Http Server Firewall, and a second network. And a virtual network corresponding to the second network.

That is, by changing the IP address of the first network allocated through the external access point and the IP address of the second network allocated through the VNIC to be the same, the first network and the second network can be treated as substantially the same network. In addition, the external device may access the second network through the IP for the second network allocated by the controller 113 and may also access the internet network through the first network.

In addition, since the first network and the second network are treated as substantially the same network, external devices are connected to the second network, but there is an advantage that the first network can be connected to the first network.

When the control unit 113 receives a transmission request for the captured image through the transceiver 119, the controller 113 may determine whether the transmission request is received through the first network or the second network.

When the transmission request for the image photographed through the first network is received, the transceiver 119 may transmit the image photographed to the Internet through the first network connected to the external access point.

On the contrary, when the transmission request for the image photographed through the second network is received, the transceiver 119 may transmit the image photographed to the external device through the second network connected to the access point unit 115.

That is, the controller 113 determines the subject requesting the image through the IP address requesting the captured image, determines the network (either the first network or the second network) including the subject, and the transceiver 119. ) May transmit the captured image through a network including the subject.

For example, when a device A connected to the second network requests transmission of a captured image, the controller 113 determines an IP address assigned to the device A from a request for transmitting the captured image, thereby subjecting the request for transmission of the captured image. Can be determined as A device. Thereafter, the transceiver 119 may transmit an image captured by the device A through the second network to which the device A is connected.

The access point unit 115 sets up a second network to which external devices are connected, and the control unit 113 connects to the second network from the external device. When receiving the connection request, the external device may be connected to the second network.

Thereafter, the control unit 113 sets a virtual network corresponding to the second network using the VNIC, and changes the address system of the virtual network to correspond to the address system of the first network, whereby the first network and the second network are substantially changed. The configuration of the first network may be changed to have the same address system.

The power supply unit 117 may supply power to the probe connection unit 110 and the light source control unit 133 according to an embodiment of the present invention.

However, the light source controller 133 may receive power from the power supply unit 117 or adjust the light amount and wavelength of the light emitting diode 131 using pre-stored power including a rechargeable battery.

The transceiver 119 transmits and receives data through an external device and an internet network, and may receive a connection request for a second network from an external device.

In addition, a transmission request for an image captured by the image photographing unit 111 may be received from at least one of an external device and an internet network.

When the transmitter / receiver 119 receives a transmission request for the captured image, the controller 113 may determine a subject of the transmission request. The transmission / reception unit 119 may transmit an image to the external device through the second network if the subject of the transmission request is an external device, and transmit the image to the internet network through the first network if the subject of the transmission request is the Internet network. .

The input unit 121 may have an interface implemented to receive a signal for adjusting the focus of the liquid lens included in the image capturing unit 111. Based on a signal for focus adjustment received through the input unit 121, the lens driving unit may adjust the focus of the liquid lens by adjusting a voltage applied to the liquid lens.

FIG. 3 is a view schematically illustrating a configuration diagram in which a wireless endoscope apparatus including an access point, an image display apparatus, and the Internet are connected according to an embodiment of the present invention.

3A is a wireless endoscope apparatus corresponding to FIG. 1, and includes a light source unit 13 including a light emitting diode 131 and a light source controller 133. FIG. 3B is a wireless endoscope apparatus corresponding to FIG. 2. The controller 133 is illustrated by way of example included in the power supply unit 117.

Referring to FIG. 3, a wireless endoscope apparatus including an access point according to an embodiment of the present invention may access an internet network by connecting to a first network through an external access point.

In addition, external devices such as a tablet PC, a smart phone, and an HMD including a NIC may access the second network set by the access point 115. By changing the address system of the second network so that the controller 113 is the same as the address system of the first network, the external devices can also access the Internet network through an external access point.

That is, the wireless endoscope apparatus including the access point according to an embodiment of the present invention sets the address system of the first network and the second network to be the same, so that external devices connected to the second network do not form a separate network. It is possible to access the internet network through the first network.

In addition, even if the position of the wireless endoscope device is changed so that the newly allocated IP address for connecting to the new first network is changed, the control unit 113 changes the second network address system to be the same as the address system of the first network. Therefore, the external devices and the wireless endoscope device can access the Internet network through the new first network without any separate setting.

4 is a flowchart schematically illustrating a method of wireless communication according to an embodiment of the present invention.

Referring to FIG. 4, in the wireless communication method according to an embodiment of the present invention, the method may include taking an image (S101), connecting to a first network (S103), and connecting an external device to a second network (S105). ), A step (S107) of creating a virtual network, a step of changing (S109), a step of receiving a transmission request (S111), a step of transmitting an image captured by an external device (S113), and an image captured by an internet network. And transmitting 115.

The step S101 of capturing an image may include capturing an image of an image coming through the probe 100, and may capture an image through a liquid lens included in the image capturing unit 111.

The step of connecting to the first network (S103) is a step of connecting to a first network connected to the Internet network through an external access point in parallel with the step of taking an image (S101), and the controller 113 connects the NIC. Through the IP can be assigned to the first network.

Connecting to the second network (S105) is a step of connecting an external device to the second network set by the access point unit 115. When receiving a connection request for the second network from the external device, the controller 113 After setting the firewall for the second network, the external device may be connected to the second network by allocating a preset IP address for the second network.

For example, external devices such as a tablet PC, a smart phone, and an HMD including a NIC may be connected to the second network.

Generating a virtual network (S107) is a step of creating a virtual network corresponding to the second network, the control unit 113 may create a virtual network corresponding to the second network using the VNIC.

For example, when connecting to a network through one NIC, since only one IP address for the connected network can be allocated, a virtual network corresponding to the second network can be created by using a virtual NIC.

In operation S109, the address system of the second network is changed by changing the address system of the virtual network to correspond to the address system of the first network.

The second network and the virtual network are networks connected to the access point unit 115, and the first network is a network connected to an external access point, and its address system is different. Therefore, by changing the address system of the virtual network to correspond to the address system of the first network, the address system of the second network can be changed to be identical to the address system of the first network.

That is, since the first network and the second network have the same address system, an external device connected to the second network can access the Internet network through the first network without a separate additional access point.

Receiving a transmission request (S111) is a step of receiving a transmission request for an image captured from an external device or an internet network.

After receiving the transmission request, the control unit 113 may determine whether the received transmission request is input through the first network or the second network.

For example, when a transmission request is input through the first network, since it is routed through an external access point, the control unit 113 transmits the transmission request through the second network and when the transmission request is input through the first network. It is possible to distinguish the input case.

In the step S113 of transmitting the captured image to the external device, when it is determined that the transmission request input by the controller 113 is input through the second network, the transceiver 119 transmits the external device through the second network. You can send the video to.

In this case, since the external device is assigned an IP for the second network set by the access point unit 115, transmission is possible without having to go through the external access point.

In the step S115 of transmitting the captured image to the Internet network, when it is determined that the transmission request input by the controller 113 is input through the first network, the transceiver 119 transmits the Internet network through the first network. You can send the video to.

In this case, since the Internet network can be connected via an external access point, the transceiver 119 can transmit an image to the Internet network via an external access point through the first network.

That is, in the wireless communication method using the wireless endoscope according to an embodiment of the present invention, a virtual network corresponding to the second network is set using a virtual NIC (VNIC) through the control unit 113, and an address system of the virtual network is provided. By changing to correspond to the address system of the first network connected to the Internet network, it is possible to change the address system of the second network connected to the access point 115 to be the same as the address system of the first network.

Therefore, there is an advantage in that the Internet network, an external access point, a wireless endoscope device, and an external device can be connected to substantially the same network without any additional access point device.
