Description

  The present invention relates to a mobile surveillance camera device. More specifically, a mobile surveillance camera device that has sufficient functionality to monitor the status of a place to be monitored, and that is easy to install because it is not restricted by the size of the installation location and the route when moving to the installation location. About.

In recent years, monitoring devices that monitor people's movements and various surrounding situations in real time or record them as images are widely used in event venues where there are many people such as fireworks festivals and festivals, as well as disaster sites and construction sites. ing. There are two types of monitoring devices, a fixed type in which a location to be monitored is fixed and operated, and a mobile type in which the location to be monitored can be changed as necessary.
Unlike the fixed type, the mobile type has the advantage of being easy to use as a general purpose because it can be operated more flexibly, for example, it can be temporarily installed on the site at a required time or time zone. As an example of such a mobile monitoring device, there is a “mobile monitoring device” of Patent Document 1.

  The mobile monitoring device disclosed in Patent Document 1 rotates in the same manner as a camera that rotates around a rotation axis that is substantially orthogonal to the road surface in the inner region of the vehicle body, and is approximately orthogonal to the rotation axis. The zoom mechanism is provided with a mirror that rotates around the line to be rotated, and is rotated in the same body as the camera. The relationship between the optical axis direction of the zoom mechanism and the vertical direction, and the direction of the optical axis and the rotation axis of the mirror. According to the relationship with the direction, the object to be monitored can be quickly monitored, and the size and weight can be reduced. Since the apparatus is provided in the vehicle body (automobile), the place to be monitored can be easily changed.

However, the conventional mobile monitoring device has the following problems.
In other words, since devices such as surveillance cameras are installed in automobiles, they cannot be installed in places where automobiles cannot enter, such as sidewalks and narrow alleys. Because of its large size, it easily disturbs the passage of pedestrians, which is dangerous and undesirable.

  In addition, among the video devices constituting the mobile monitoring device, only the mirror is exposed to the outside of the vehicle body and is visible from the outside, and the camera itself is contained in the vehicle body and cannot be seen. Therefore, the mobile monitoring device is hardly conspicuous as a monitoring device and is not attracting much attention. For this reason, even if the functionality as a means for monitoring the situation in the field is sufficient, for example, the deterrent effect that prevents the occurrence of crimes and troubles such as violence and theft has not been expected.

  The present invention has been devised in view of the above points, and has sufficient functionality as a means for monitoring the situation of a place to be monitored, and at the time of moving to the size of the installation location or the installation location. It is an object of the present invention to provide a mobile surveillance camera device that is not easily restricted by a route and is easy to install.

  Another object of the present invention is to actively appeal to the surroundings of the presence of the mobile surveillance camera device, for example, to encourage the self-control of many spectators who participated in events, etc. It is to be able to prevent crimes and other troubles from occurring even under difficult circumstances.

(1) The present invention relates to a hand-drawn cart, a camera attached to the cart, the height and the shooting direction of which can be adjusted, a transmission device that transmits video data captured by the camera to a receiving device, and the cart It is a mobile surveillance camera device that is attached and includes power supply means for supplying power to the camera and the transmission device.

(2) The present invention may be configured to include a warning unit that actively appeals the presence of the mobile monitoring camera device to the surroundings.

  In this case, by virtue of proactively appealing the presence of the mobile surveillance camera device to the surroundings by warning means, or by threatening in some circumstances, for example, many individuals who participated in an event etc. Such a situation is created by encouraging the audience's sense of excitement and, moreover, by encouraging the self-control of those who share the so-called collective psychology that would be cast into a specific action without reasonably judging it. The occurrence of crimes and other troubles can be prevented in advance.

(3) In the present invention, the power supply means may include an engine generator.

  In this case, an engine sound is generated by the operation of the engine, and the engine can also serve as a sound generation device, that is, a warning means. Therefore, the above-described warning means is effective when the presence of the mobile monitoring camera device is actively appealed to the surroundings. Can assist. In addition, although the engine-type generator requires time for refueling, it can be operated (operated) for a long time, so that it can be operated at any place in terms of continuously supplying power.

(4) The present invention may be configured such that the transmission device belongs to the same wireless network as the reception device to which the transmission device sends video data.

  In this case, the video data transmitted from the transmission device is transmitted wirelessly to the reception device, and the video can be viewed by the reception device, so that cable processing is performed as in the case of wired communication using a cable. Can be eliminated. In addition, for example, by using an Internet line or a mobile phone line as a wireless network, it is possible to monitor using a receiving device even at a location far away from the location to be monitored (location of the mobile surveillance camera device). become.

(5) The present invention may include a height adjustment device that adjusts the height of the camera by rotating the handle, and the height adjustment device may include a lock mechanism unit that stops the rotation of the handle. .

  In this case, it can be fixed so that the height position of the camera does not change. In other words, because the camera is relatively heavy, if you move the monitoring device with the camera raised, there is a risk that the handle will turn due to shocks caused by unevenness on the road surface, causing the camera to fall suddenly downward. The danger can be eliminated by preventing the handle from turning in the lock mechanism.

Please refer to FIG. 1 to FIG.
In this embodiment, the mobile monitoring camera device A is used in combination with a personal computer 7 that is a receiving device and has a wireless communication function (see FIG. 7).

  The mobile surveillance camera device A has a carriage 1. The carriage 1 has a box-shaped main body 10 made of metal and formed in a hollow body having a rectangular parallelepiped shape, and casters 11 are attached to four corners of the bottom of the main body 10. A handle 12 for pushing is fixed to one end side (the right end side in FIG. 1) of the upper surface of the main body 10. An engine generator 2 is housed inside the main body 10. A fuel tank 20 is disposed on the top of the generator 2.

  The electric power generated by the generator 2 is converted into direct current by the power supply unit 21 and supplied to the network cameras 4, 4a, 4b and the wireless LAN router 5 described later. Further, AC power is supplied from the generator 2 to the rotating lamp 6 described later (see FIG. 7).

  The carriage 1 is provided with a telescopic column 3. The telescopic strut 3 has a nested structure composed of three-stage strut members 30, 31, 32 that extend and contract in the vertical direction from one end of the upper surface of the main body 10. When the telescopic strut 3 is contracted the most, the strut members 31 and 32 are accommodated in the lowermost strut member 30.

  The telescopic support column 3 can be expanded and contracted by operating an expansion / contraction operation device 33 which is a height adjusting device. The telescopic operation device 33 has a structure in which the telescopic support column 3 can be expanded and contracted by manually rotating the rotating handle 331 in the forward and reverse directions. The telescopic operation device 33 is a known general device having a mechanism in which a gear and a wire are combined, and thus a detailed description of the structure is omitted.

The lock mechanism 34 is provided on the upper surface side of the case 332 in which the mechanism of the telescopic operation device 33 is housed. The lock mechanism 34 has a rectangular guide board 341 in plan view. A guide gap 342 is formed on the lower surface side of the intermediate portion in the width direction of the guide panel 341. In the guide panel 341, a rectangular opening 343 is formed on the guide gap 342.

  A sliding member 344 having three locking claws 344a, 344b, and 344c at its tip is inserted into the guide gap 342 so as to be able to advance and retract. A locking angle 345 protruding upward and penetrating through the opening 343 is formed at the rear end of the sliding member 344. A locking angle 346 is formed on the upper surface side of the guide board 341 and on the front side of the opening 343 so as to protrude upward. The locking angles 345 and 346 are formed with holes (not shown) through which the U-shaped metal fittings of the lock are passed.

  Then, as the sliding member 344 advances from the guide gap 342, the upper L-shaped lock claw 344a is positioned outside the rim 331a of the rotary handle 331, and the other straight-type lock claws 344b and 344c are The rim 331a is engaged with the inner periphery of the rim 331a so as to sandwich the single spoke 331b from both sides. In this state, the locking angles 345 and 346 are close to each other, so that the rotary handle 331 can be locked by locking the lock 8 in the hole and preventing the sliding member 344 from moving.

  In addition, three network cameras 4, 4 a, 4 b are provided on the upper part of the telescopic support column 3. The network cameras 4, 4a and 4b have a recording function capable of recording video on a memory card such as an SD card. The network cameras 4, 4 a, and 4 b are attached to the upper part of the uppermost support member 32 via an attachment member 40. The network cameras 4, 4 a, 4 b are attached at an equal angle (120 °) in the axial circumferential direction with the support column member 32 as the central axis, and the shooting direction is substantially horizontal and radial (see FIGS. 3). The network cameras 4, 4 a, and 4 b can be adjusted in the vertical direction within a certain range by a screw tightening structure (see FIG. 1). In the present embodiment, the orientation of the network cameras 4, 4a, 4b in the axial direction is fixed in the direction shown in FIGS. 1 to 3, but may be directed in an appropriate direction different from that, manually or automatically. You may be able to adjust with.

  On the attachment member 40, a case 50 is attached, in which the wireless LAN router 5 as a transmission device is accommodated and fixed. Connected to the wireless LAN router 5 is a LAN cable 41 (see FIG. 7) extended from the network cameras 4, 4a, 4b. Note that the network cameras 4, 4a, 4b have a recording function capable of recording video on a memory card as described above, and can record (record) video in real time while transmitting video data. A rotating lamp 6 is attached above the case 50 via an L-shaped angle 60.

  The mobile surveillance camera device A has the above-described structure, and is formed to a size that can be moved even on a sidewalk where a car cannot enter, a narrow road, or an alley (see FIG. 6). The mobile surveillance camera device A is made to have a weight of about 260 kg in the present embodiment, and the difficulty of carrying it as one of the theft countermeasures.

On the other hand, the personal computer 7 which is a receiving apparatus shown in FIG. 7 is a so-called notebook personal computer having a display 70. The personal computer 7 and the wireless LAN router 5 are set to belong to the same LAN (Local Area Network) which is a wireless network.
By using a dedicated application on the display 70, the video of the network camera 4 is displayed on the display unit 71, the video of the network camera 4a is displayed on the display unit 72, and the video of the network camera 4b is displayed on the display unit 73 in real time. Can be displayed.

(Function)
The operation of the mobile surveillance camera device A will be described with reference to FIGS.
When the mobile monitoring camera device A is installed at an event venue or the like to be monitored, first, the mobile monitoring camera device A is loaded on a truck, etc. It is transported together with the computer 7. Then, the worker M removes the mobile monitoring camera device A from the automobile and moves to the installation location by manually pushing it as shown in FIG.

  In this way, the mobile monitoring camera device A does not move to the installation location for each vehicle, unlike the conventional monitoring device, but moves to a location where it can be moved by the vehicle, away from the location from the location to the installation location. Can be moved. Further, as described above, since the mobile surveillance camera device A is made compact, it can move relatively easily even on sidewalks, narrow alleys, places with poor road surfaces, or slopes, and has a wide installation location. It is easy to install because it is difficult to be restricted by the path when moving to the sheath.

  At the site, the caster 11 is locked so that the carriage 1 does not move. Then, the network camera 4, 4a, 4b is raised to a required height by operating the rotary handle 331 of the telescopic operation device 33 (see FIGS. 1 and 2). When the heights of the network cameras 4, 4a and 4b are determined, the lock mechanism 34 is operated to lock the rotation handle 331 so as not to rotate. Thereby, there is no danger that the network cameras 4, 4 a, 4 b set at a high position suddenly fall downward, and safety can be achieved.

  Next, the generator 2 is started, and the generated electric power is supplied to the rotary lamp 6, the network cameras 4, 4a, 4b, and the wireless LAN router 5. Thereby, the operation sound of the engine-type generator 2 is generated and the rotating lamp 6 is operated. Note that the generator 2 does not require refueling, but it can be operated for a long time, so that it can be operated at any place in terms of continuously supplying power.

  In addition, the operation sound (engine sound) and the operation of the rotating lamp 6 can alert the surroundings as warning means or intimidation means to actively appeal the presence of the mobile monitoring camera device A to the surroundings. For example, it is possible to prevent crimes and other troubles from occurring even under such circumstances by encouraging self-control through the sense of excitement of a large number of spectators who participated in an event.

Further, the network camera 4, 4 a, 4 b starts photographing the surroundings, and the wireless LAN router 5 transmits the video data sent from the network camera 4, 4 a, 4 b. In addition, video is recorded on the memory card. This recorded video can be reproduced by the personal computer 7 or the like as necessary.
The transmitted video data is displayed in real time on the respective display units 71, 72, 73 of the personal computer 7 in the vicinity where the monitor is stationed, and the monitor uses this video to display the mobile monitoring camera device A. The surrounding situation can be monitored.
