DETAILED DESCRIPTION OF THE INVENTION

[0009] FIG. 8 shows the configuration of a conventional disaster prevention monitoring system 5. In the disaster prevention monitoring system 5, a base unit 51 is equipped with a fire receiver R, a communication base unit main unit 511, and a base unit handset 512. The fire receiver R is connected to multiple fire detectors S via detection lines L and receives fire detection signals. The communication base unit main unit 511 is connected to the base unit handset 512 via a wire. Meanwhile, in the handset 52, a handset 522 is connected to the handset main unit 521 via a wire. The communication base unit main unit 511 and the handset main unit 521 are connected via a communication wiring 53. This allows the handset 522 of the handset 52 to communicate with the base unit handset 512 via audio signals via the communication wiring 53. In the event of a fire, a person in charge near the base unit 51 and a person near the handset 52 can communicate with each other about the fire situation, allowing the person in charge to understand the situation at the scene. [Example]

[0010] However, there are cases where the situation at the site can be more easily conveyed by video than by phone. Therefore, in the present invention, a camera device is used to transmit the video of the site to the base unit. Figure 1 shows the camera device 123 in the first embodiment. Figure 1(a) is a front view, and Figure 1(b) is a side view. Figure 1(b) is a view seen from the direction of the arrow in Figure 1(a), and Figure 1(a) is a view seen from the direction of the arrow in Figure 1(b).

[0011] Camera device 123 comprises photographing section 123a, display section 123b, grip section 123c, and cord 123d. Photographing section 123a, which is the camera body, is provided on the back side of display section 123b, which is a flat panel display, and an image captured by photographing section 123a is displayed on display section 123b. Photographing section 123a has a lens and an image sensor. Columnar grip section 123c is provided below display section 123b, and can be held in the hand when taking pictures. Cord 123d extends from below grip section 123c.

[0012] Fig. 2 shows the configuration of the disaster prevention monitoring system 1 in Example 1. The disaster prevention monitoring system 1 includes a base unit 11, a detection line L, a fire detector S, a call wiring 13, and a handset 12. The base unit 11 includes a fire detector R, a call base unit main body 111, and a base unit handset 112. In the state shown in Fig. 2, the base unit handset 112 is housed in the call base unit main body 111. The call base unit main body 111 includes a display device 111a.

[0013] The fire receiver R of the base unit 11 is connected to a plurality of fire detectors S via a detection line L and receives fire detection signals. The call base unit main body 111 is connected to the base unit handset 112 by wire (not shown).

[0014] In addition, in handset 12, handset handset 122 and camera device 123 are connected to handset main unit 121 by wire. Communication base unit main unit 111 and handset main unit 121 are connected by communication wiring 13. This allows handset handset 122 of handset 12 to communicate with base unit handset 112 by audio signals via communication wiring 13. In addition, images captured by camera device 123 are transmitted to communication base unit main unit 111 by video signals via communication wiring 13, and the camera image is displayed as a moving image on display device 111a.

[0015] The handset 122 and camera device 123 of the handset 12 can be detached from the handset body 121 and used. The handset 122 can be detached from the handset 12 to make a call with the base unit handset 112 of the base unit 11. When either the handset 122 or the camera device 123 is detached from the handset body 121, the camera device 123 starts taking video, displays the video on the display unit 123b, and transmits a video signal to the base unit 11 via the call wiring 13.

[0016] When using the handset 12, the user holds the handset 122 (described later) to their head to make a call, and, if necessary, can point the image capturing unit 123a of the camera device 123 at a fire or the like to capture an image. When a fire breaks out, the user removes the handset 122 from the handset 12 near the fire scene, talks with the base unit handset 112 of the base unit 11, and removes the camera device 123 from the handset 12. The camera is connected to the handset body 121 by a cord 123d, and can be moved within the reach of the cord 123d. Therefore, the image capturing unit 123a of the camera device 123 can be pointed at the fire to capture a moving image, and the obtained video signal can be sent to the base unit 11 via the call wiring 13 and displayed as a moving image on the display device 111a.

[0017] In the first embodiment, the communication wiring 13 is used to transmit video signals of moving images, and therefore a video signal of moving images with a lower resolution than that which can be captured by the image capturing unit 123a of the camera device 123 is transmitted to the communication base unit main body 111. When a high-resolution still image is to be transmitted, the voice command "shutter on" is input from the handset 122 or the base unit handset 112 during a conversation. The handset main body 121 recognizes this voice and generates a high-resolution still image. Then, transmission of the video signal of the moving image is interrupted, and the still image is transmitted to the communication base unit main body 111 and displayed on the display device 111a. Note that a still image may be captured by providing a shutter without using voice recognition.

[0018] <Modification> In the first embodiment, the video captured by the camera device 123 of the handset 12 is displayed only on the display device 111a of the base unit 11. However, a disaster prevention monitoring system may be provided with a plurality of handset devices 12, and the audio and video signals of the handset 12 may also be received by the other handset devices 12, and the audio and video signals may be emitted and displayed. In a modified example, when the camera device 123 is detached from the handset body 121, the imaging unit 123a starts capturing video, and the video is displayed on the display unit 123b, and the video signal is transmitted via the communication wiring 13. The base unit 11 receives the video signal and displays the video on the display device 111a. Furthermore, in the other handset devices 12, when the handset 122 is detached from the handset body 121, the video based on the received video signal is displayed on the display unit 123b of the camera device 123. In the modified example, when camera device 123 is detached from handset main body 121 of handset 12, an image is taken, and when handset 122 is detached without detaching camera device 123, an image taken by another handset 12 is displayed on display unit 123b. When camera devices 123 are detached from multiple handset units 12, the image of the handset 12 that was detached first is displayed preferentially. The moving image displayed on display unit 123b of handset 12 is also displayed on display unit 111a of base unit 11 in the same way. [Example]

[0019] The handset 12 in the first embodiment includes a handset 122 and a camera device 123. In the second embodiment, the handset and the camera device are integrated to form a transceiver camera 222. Fig. 3 shows the transceiver camera 222 in the second embodiment. Fig. 3(a) is a front view, and Fig. 3(b) is a side view. When viewed from the direction of the arrow in Fig. 3(a), it becomes Fig. 3(b), and when viewed from the direction of the arrow in Fig. 3(b), it becomes Fig. 3(a).

[0020] The transmitting / receiving camera 222 comprises a photographing section 222a, a display section 222b, a grip section 222c, and a cord 222d. The photographing section 222a, which is the camera body, is provided on the back side of the display section 222b, and the image captured by the photographing section 222a is displayed on the display section 222b. The photographing section 222a has a lens and an image sensor. A cylindrical grip section 222c is provided below the display section 222b, and can be held in the hand when taking pictures or making calls. A cord 222d extends from below the grip section 222c.

[0021] The handset camera 222 of the second embodiment further includes a microphone 222e and a speaker 222f, and functions as both a camera device and a handset. The microphone 222e is provided on the grip part 222c near the display part 222b. The speaker 222f is provided on the opposite side of the display part 222b from the grip part 222c. The microphone 222e and the speaker 222f face in the same direction as the display part 222b, and the microphone 222e is directional. During use, the user can point the imaging part 222a at a fire or the like to capture an image, and point the display part 222b at the user's face to make a call.

[0022] Fig. 4 shows the configuration of a disaster prevention monitoring system 2 in Example 2. The disaster prevention monitoring system 2 includes a base unit 21, a detection line L, a fire detector S, a call wiring 23, and a handset 22. The base unit 21 includes a fire detector R, a call base unit main body 211, and a base unit handset 212. The base unit handset 212 is connected to the call base unit main body 211 by a wire (not shown). In the state shown in Fig. 4, the base unit handset 212 is housed in the call base unit main body 211. The call base unit main body 211 includes a display device 211a.

[0023] The fire receiver R of the base unit 21 is connected to a plurality of fire detectors S via a detection line L, and receives fire detection signals. The communication base unit main body 211 is connected to the base unit handset 212 by wire.

[0024] In addition, in the handset 22, a transceiver camera 222 is connected to the handset main body 221 by a wire. The communication base unit main body 211 and the handset main body 221 are connected by a communication wiring 23. This allows the transceiver camera 222 of the handset 22 to communicate with the base unit handset 212 by audio signals via the communication wiring 23. In addition, an image captured by the transceiver camera 222 is transmitted to the communication base unit main body 211 by a video signal via the communication wiring 23, and the camera image is displayed as a moving image on the display device 211a.

[0025] The handset 22's transceiver camera 222 can be detached from the handset main body 221 and used. Therefore, the handset 22 can detach the transceiver camera 222 from the handset main body 221 and talk with the base unit handset 212 of the base unit 21. When the transceiver camera 222 is detached from the handset main body 221, it starts shooting, displays the captured video on the display unit 222b, and transmits a video signal to the base unit 21 via the call wiring 23. The video is then displayed on the display device 211a.

[0026] When a fire breaks out, the handset camera 222 can be removed from the handset 22 near the fire scene, and the handset camera 222 can be used to talk to and take pictures from the handset handset 212 of the base unit 21. The handset camera 222 is connected to the handset body 221 by the cord 222d, and can therefore be moved within the reach of the cord 222d. Therefore, it is possible to point the camera unit 222a of the handset camera 222 at the fire to take pictures, and send the obtained video signal to the base unit 21 via the call wiring 23, and display the video on the display device 211a. As the handset and camera device of the handset camera 222 are integrated, both talking and taking pictures can be done with one hand.

[0027] <Modification> The modified example of the transceiver camera 223 in the second embodiment has a shape similar to that of a normal handset. The modified example of the transceiver camera 223 also has the handset and camera device integrally formed. The configuration of the disaster prevention monitoring system other than the transceiver camera 223 is the same as that of the disaster prevention monitoring system 2 in the second embodiment.

[0028] FIG. 5 shows a transceiver camera 223 in a modified example of the second embodiment. Similar to a handset, the transceiver camera 223 has a microphone 223e and a speaker 223f near both ends of a grip 223c. An image capturing unit 223a is provided on the grip 223c near the speaker 223f. The image capturing unit 223a is attached to the grip 223c and faces in a direction substantially perpendicular to the speaker 223f. A cord 223d is connected to the lower end of the grip 223c, and the transceiver camera 223 is connected to the handset body via the cord 223d. The image capturing unit 223a has a lens and an imaging element, and its base is mounted on a spherical body and is movable around the spherical body 223g as shown by the arrow, allowing the direction from the grip 223c to be adjusted to a certain extent.

[0029] The handset camera 223 does not have a display unit. However, it has a shape similar to that of the conventional handset 522 shown in Fig. 8, and can be used by placing it next to the head. When using it, the camera unit 223a can be pointed in the direction of the fire to capture an image of the fire. [Example]

[0030] The camera device 123 of the first embodiment can be made wearable. In the third embodiment, an example of a wearable device will be shown in which a camera is attached to a helmet. FIG. 6 shows the camera device 323 attached to a helmet 324 in the third embodiment. The camera device 323 includes an image capturing unit 323a and an image transmitting unit 323b that transmits images wirelessly. The camera device 323 of the third embodiment is attached to the side of the helmet 324, not below it, and is provided in a location that does not contact the wearer's ear. Therefore, it is unlikely to be an obstacle when the wearer makes a call using a handset 322, which will be described later. However, the camera device 323 may also be attached to the bottom of the helmet 324.

[0031] Fig. 7 shows the configuration of a disaster prevention monitoring system 3 in Example 3. The disaster prevention monitoring system 3 includes a base unit 31, a detection line L, a fire detector S, a call wiring 33, and a handset 32. The base unit 31 includes a fire detector R, a call base unit main body 311, and a base unit handset 312. In the state shown in Fig. 7, the base unit handset 312 is housed in the call base unit main body 311. The call base unit main body 311 includes a display device 311a.

[0032] The fire receiver R of the base unit 31 is connected to a plurality of fire detectors S via a detection line L, and receives fire detection signals. The call base unit main body 311 is connected to the base unit handset 312 by wire (not shown).

[0033] Moreover, in the handset 32, the handset main body 321 is provided with a video receiving unit 321a, and is connected to the handset handset 322 by a wire. The communication base unit main body 311 and the handset main body 321 are connected by a communication wiring 33. This allows the handset handset 322 of the handset 32 ​​to communicate with the base unit handset 312 by audio signals via the communication wiring 33. Furthermore, an image captured by the camera device 323 is wirelessly transmitted by the video transmitting unit 323b and received by the video receiving unit 321a of the handset main body 321. The video signal is then transmitted to the communication base unit main body 311 via the communication wiring 33, and is displayed as a moving image on the display device 311a. In the third embodiment, the wireless transmission of the video signal is performed by Bluetooth (registered trademark).

[0034] The handset 322 and camera device 323 of the handset 32 ​​are prepared and used separately from the handset main body 321. If the video receiving unit 321a is within a distance where video can be transmitted, the video transmitting unit 323b connects to it and transmits a video signal wirelessly. When the video receiving unit 321a receives the video, the handset 32 ​​transmits the video signal to the base unit 31 via the communication wiring 33.

[0035] When a fire breaks out, a person in charge puts on a helmet 324 and heads to the fire scene. Camera device 323 attached to helmet 324 then begins capturing images using image capturing unit 323a, searches for image receiving unit 321a capable of wireless transmission, and wirelessly transmits a video signal from image transmitting unit 323b. When handset 322 is taken out of handset 32 ​​near the fire scene and attempts to communicate with base unit handset 312 of base unit 31, handset body 321 is nearby, enabling wireless transmission of video signals between image transmitting unit 323b and image receiving unit 321a. The video signal is then sent to base unit 31 via communication wiring 33, and the camera image can be displayed as a moving image on display device 311a.

[0036] Even if the handset 322 of the handset 32 ​​is not receiving a video signal at the video receiving unit 321a, the handset 322 can communicate with the base handset 312 of the base unit 31. Therefore, even if a person does not have the camera device 323, the situation of the fire can be communicated to the base unit 31 by communication.

[0037] The wearable camera device 323 of the third embodiment may be attached to something other than the helmet 324. For example, it may be attached to goggles or eyeglasses. It may also be attached to clothing, such as being placed in a breast pocket and attached to clothing with the image capturing unit facing outward. A helmet 324 may also be installed for each slave unit 32.

[0038] In the first and second embodiments, the camera device 123 and the transmitting / receiving camera 222 are connected to the handset main unit 121 and the handset main unit 221 via the cord 123d and the cord 222d. However, as in the third embodiment, wireless transmission may be used. In the first to third embodiments, the fire receiver R is provided inside the base unit 11, 21, and 31 and integrated with them. However, the base unit and the fire receiver R may be configured as separate units. Also, in the first to third embodiments, the video signal is sent via the call wiring 13, 23, and 33. However, a power line may be provided to supply power from the base unit to the handset, and the video signal may be sent using the power line. Also, a video wiring separate from the call wiring may be provided between the base unit and the handset, and the video signal may be sent using the video wiring.

[0039] Furthermore, the specific configuration is not limited to the embodiments, and the present invention includes design changes within the scope of the gist of the present invention. Furthermore, the above-mentioned examples and modifications can be combined by utilizing each other's technology as long as there are no particular contradictions or problems in the purpose, configuration, etc. [Explanation of symbols]
