Description

  The present invention relates to an equipment abnormality detection system for transferring a video image of equipment from the site to the management site in order to determine whether the facility at the site is in an abnormal state in appearance. . In detail, for example, in determining whether a facility such as a conduit in the lifeline has been destroyed or damaged due to a natural disaster or intentional mischief by a malicious intruder, The present invention relates to an equipment abnormality detection system that detects the state of equipment.

  As one of the infrastructures (abbreviation: infrastructure), for example, gas conduits for sending fuel gas and tap water conduits for supplying clean water have been established throughout the region. Most of these conduits are buried in the ground, but in addition to the areas that cross rivers, some of the conduits are constructed by bridge girders and pipes due to topographical conditions and restrictions due to the location of buildings. It is laid on a beam.

  In places where the conduits are exposed to the ground, for example, malicious intruders perform mischief on the conduits, and the contractor is working on unmanaged facilities adjacent to the conduits being managed In the meantime, if an accident that accidentally damages the conduit to be managed occurs, the original function of the conduit may be impaired and it may not function normally, or it may cause a dangerous condition. Yes, for security reasons. In addition, for example, the conduit is destroyed by natural disasters such as local heavy rains, tornadoes, earthquakes and accompanying tsunamis, and it does not function normally due to damage. There is also a risk of changing to an abnormal state, and it is necessary to manage the conduit for maintenance. As one of countermeasures for managing such a conduit at a management site away from the site, a crime prevention monitoring system with a camera disclosed in Patent Document 1 and a crop growth status monitoring system disclosed in Patent Document 2 Can be considered. FIG. 13 is a schematic diagram showing a security monitoring system with a camera disclosed in Patent Document 1, and FIG. 14 is a schematic diagram showing a crop growth status monitoring system disclosed in Patent Document 2.

Patent Document 1 discloses a method of photographing a trespasser detected by an infrared sensor at a monitoring site such as an aquaculture farm with a network camera while illuminating it with a projector, and sending the video to a personal computer at the same time by e-mail. This is a monitoring system that informs the user of a personal computer by an e-mail of a mobile phone and then confirms the status of the surveillance site from the video received by the personal computer.
As shown in FIG. 13, this monitoring system covers a power source by charging the storage battery 113 with the power generated by the solar power generation device 111. When the infrared sensor 101 detects an illegal intruder, the camera drive motor 106 While the network camera 105 rotates together with the projector 104, the state of the illegal intruder is photographed over a wide range of the monitoring site.

  In Patent Document 2, a mobile terminal device is remotely operated from a place distant from the crop cultivated land, the state of the crop is photographed with a digital camera in the crop cultivated land, and the still image is taken as the crop cultivated land via the Internet. This is a monitor system that transmits to an image server installed at a distant place and displays it on a monitor to check the growth status of the crop. In Patent Document 2, as shown in FIG. 14, an image for storing a still image in addition to a storage battery 214 and a digital camera 218 that charge power generated by a solar battery 212 to a monitor device 210 installed on a crop cultivated land 202. The monitor system 201 includes a memory 222, a transmission / reception device 224 that transmits and receives signals to and from the mobile terminal device 250 and the image server 230 via the Internet.

  However, in Patent Document 1, it is necessary to constantly monitor the surveillance site with an infrared sensor, and an illegal intruder who has entered the surveillance site is photographed for about 10 minutes while rotating the projector and the network camera by the camera drive motor. Therefore, power consumption is high in each device such as an infrared sensor, a camera drive motor projector, and a network camera. In addition, Patent Document 1 does not provide any device for suppressing the power consumption of these devices. In addition, the power source is covered by charging the storage battery with the power generated by the solar power generation device without using a commercial power source. If the power consumption of the entire system increases, the power source is lost due to overdischarge of the storage battery. There is a risk of inviting.

  In addition, Patent Document 2 allows the owner of the mobile terminal device to control the monitor device by remote control and change the shooting conditions of the digital camera more clearly to grasp the growing situation of the crop, and to capture the captured image. The number of parts is increased and the cost is high due to the multi-functionality of the system, such as being able to select the timing for temporarily storing the image in the image memory and transmitting the image to the image server.

  By the way, as a lifeline, at a conduit exposure site where a conduit is laid over a river girder across a river, intentional accidents caused by natural disasters or mischief of intruders with malicious intentions, and accidental damage to conduits by contractors When installing an equipment abnormality detection system that detects whether the conduit is broken, damaged, or the like, the power source of the system is preferably a storage battery. If a power failure occurs during a natural disaster such as heavy rain, a tornado, an earthquake, or a tsunami that accompanies it, the commercial power supply loses its system power and stops functioning. This is because the system can be operated regardless of the power outage by making the storage battery charged. However, if the storage battery installed at the site where the conduit is exposed becomes large enough to be applied to the Fire Service Law, a complicated procedure is required to install the storage battery, which is troublesome. In addition, when it is desired to change the installation location of the system, it becomes difficult to move the system. Therefore, it is preferable to reduce the size of the storage battery as much as possible. To reduce the size of the storage battery, the power consumed by the system needs to be suppressed as much as possible. Since Patent Document 1 does not take measures to suppress power consumed by the monitoring system, it is difficult to use it as an equipment abnormality detection system from the viewpoint of stable power supply.

  Moreover, the above-mentioned conduit exposure sites are scattered in a plurality of locations over a wide area in each region, and even in a single exposure site, the equipment abnormality detection system can sufficiently detect a conduit straddling a river with one visual field. First, it is necessary to detect from a plurality of visual fields. Furthermore, in order to prepare for unexpected accidents due to mischief of malicious intruders, accidental damage to conduits by construction contractors, and natural disasters, an equipment abnormality detection system is installed in such conduits that are public facilities. Then, there are circumstances in each region where the installation of the system is not promoted unless the initial cost and the running cost accompanying the investment of the system are low. In each region, a low-cost equipment abnormality detection system has been demanded, but no system that meets the demand has been developed so far. Patent Document 2 is also difficult to use as an equipment abnormality detection system because of its high cost.

  The present invention has been made in order to solve the above-described problems, and in determining whether the on-site equipment has changed to an abnormal state in appearance, it is necessary to determine the cost at a management site far from the site.

At the same time, video or image is transmitted to the management terminal by the Internet connection transmission / reception means, and after the time is up, the power supply to the camera is turned off, and at the same time, the power supply from the power source to the signal input / output means is turned back on. Power consumption control means for performing energization timer control for disconnecting communication by the means.

It is a secondary battery having cycle use characteristics that are repeatedly used a plurality of times.
(3) In the equipment abnormality detection system described in (1) or (2), while automatically controlling the charging voltage charged to the storage battery through the photovoltaic power generation panel, in the state where the storage battery has become low voltage, Charge / discharge control means for automatically interrupting discharge is provided.
(4) In the equipment abnormality detection system described in (3), the charge / discharge control means has a backflow prevention function for preventing current from flowing from the storage battery toward the photovoltaic power generation panel.
(5) In the equipment abnormality detection system according to any one of (1) to (4), a function confirmation server is provided separately from the server, and the function confirmation server outputs a timer start signal by a signal input / output means. The second instruction signal for output is provided so that it can be transmitted to the Internet connection transmission / reception means, and the function confirmation server is detected under the control of the power consumption control means based on the input timer start signal. The object is photographed with a camera, and an image or an image of the object to be detected transmitted simultaneously with the photographing by the Internet connection transmission / reception means is provided so as to be stored.
(6) In the equipment abnormality detection system according to any one of (1) to (5), the equipment abnormality detection system includes an illuminating lamp that projects light on an object to be detected at the time of photographing with a camera. Switch on / off the power to the lamp according to the on / off of the power to the camera, the camera is a network camera that captures moving images or still images, and the object to be detected captured by the camera These images or images are transmitted at the same time as photographing by the Internet connection transmission / reception means, and can be disclosed by the management terminal at the management base.
(7) In the equipment abnormality detection system according to any one of (1) to (6), the object to be detected is a conduit laid on a erection means laid on the ground. .
The “erection means” means a facility that spans and connects between at least two points separated from each other on the ground, such as a bridge, a bridge girder, and a pipe beam. The object can be maintained between the at least two points and supported above the ground.

  The operation and effect of the equipment abnormality detection system of the present invention having the above configuration will be described.

(1) Internet connection transmission / reception capable of transmitting a video or an image captured by a camera to a management site and receiving a first instruction signal from the management site via a power source, a camera, and the Internet connected via a server. In order to determine whether the detected object at the site remote from the management site is in an abnormal state, the management site displays the video or image of the detected object. In the equipment abnormality detection system to be transferred to the management terminal installed in the power supply, the power source is a storage battery in which the power generated by the solar power generation panel is stored, based on the first instruction signal input through the Internet connection transmission / reception means, While the signal input / output means for outputting the timer start signal and the Internet connection transmission / reception means are always in operation, the signal input / output means The power supply from the power supply to the signal input / output means is turned off by the input timer start signal, and at the same time, the power supply from the power supply to the camera is turned on, and the object to be detected is photographed with the camera for a preset time. At the same time, video or image is transmitted to the management terminal by the Internet connection transmission / reception means, and after the time is up, the power supply to the camera is turned off, and at the same time, the power supply from the power source to the signal input / output means is turned back on. Power consumption control means for performing energization timer control for cutting off communication by the means, so that the object to be detected is, for example, a gas conduit for sending fuel gas, a tap water conduit for flowing clean water, etc. In the case of a conduit that becomes a lifeline, in addition to the area straddling the river, the conduit may be on the ground due to topographical conditions or restrictions due to the location of the building. Erection was, for example, bridge beams, there is laid conduits exposed scene pipe beam, etc. (site). In the facility abnormality detection system of the present invention, as a preset time, for example, the shooting time per time is 3 minutes, the number of times of shooting per day is 8 times every 3 hours, etc. It can be a system suitable for such a site that only needs to be able to shoot intermittently in a short time to determine the state of the object to be detected.

  That is, since the facility abnormality detection system of the present invention is a storage battery that stores power generated by solar power generation, in particular, due to natural disasters such as heavy rains, tornadoes, earthquakes and accompanying tsunamis, etc. Even if a power failure occurs, it is assumed that loss of power to the equipment abnormality detection system can be avoided. In addition, when the Internet connection transmitting / receiving means receives the first instruction signal from the management base side, it waits for the first instruction signal so that the image of the detected object can be transmitted to the management terminal of the management base. In a situation where the power consumption control means does not need to maintain the operation state for the camera and the signal input / output means while maintaining the Internet connection transmission / reception means with relatively low power consumption at all times. The power is turned off to prevent unnecessary power consumption. As a result, the object to be detected (conduit) at the site is intentionally caused by a natural disaster such as heavy rain, a tornado, an earthquake or a tsunami that accompanies it, or a malicious intruder's mischief. In order to determine at the management site whether there has been destruction, damage, etc. due to a damage accident, etc., the facility abnormality detection system of the present invention can suppress less power consumption and stabilize the power supply. Secured. As a result, it is not necessary to store large-capacity electric power generated using a larger photovoltaic power generation panel in a larger storage battery, and the photovoltaic power generation panel and storage battery can be installed in a small space and the power supply can be made compact. Thus, the degree of freedom with which the facility abnormality detection system of the present invention can be installed on site is further increased.

  Moreover, the equipment abnormality detection system of the present invention captures an object to be detected with a camera for a preset time, and transmits an image or the like as it is to a management terminal by means of an internet connection transmitting / receiving means. Therefore, the facility abnormality detection system according to the present invention is configured as a multi-functional system such as a memory for temporarily storing captured images and the like, and a timing for transmitting the images to the server. Unlike the technology, the number of parts can be reduced, and the manufacturing cost can be reduced. In particular, the facility abnormality detection system of the present invention can be used to determine the state of the detected object for security and maintenance, and to shoot the detected object and its surroundings in a short time and intermittently. Since it is configured with the minimum necessary number of parts, the entire system can be reduced in size. Therefore, as described above, the degree of freedom of the location where the equipment abnormality detection system of the present invention can be installed is greater and can be easily installed, and when the installation location is changed, the equipment abnormality detection system of the present invention can also be installed. Relocation is easy. Moreover, since it is not necessary to select the specifications for large-capacity power for the above-described solar power generation panel and storage battery, the initial cost applied to the power supply is low. Furthermore, in the wireless communication when the Internet connection transmission / reception means receives the first instruction signal from the management base side, or the wireless communication when the Internet connection transmission / reception means transmits the image of the detected object to the management terminal, For example, by using a high-speed mobile communication medium using a communication technology such as Mobile WiMAX (Mobile Worldwide Interoperability for Microwave Access), it is possible to suppress a running cost for wireless communication. In addition, for example, when the camera is a network camera and the previously illustrated mobile WiMAX or the like is used, the image of the object to be detected can be transmitted with high resolution image quality by high-speed communication such as mobile WiMAX. The video received by the management terminal at the management site is clear. Therefore, an administrator at a management site away from the site can quickly and clearly determine whether the object to be detected on the site has changed to an abnormal state in appearance.

  Therefore, according to the facility abnormality detection system of the present invention, in order to determine whether the object to be detected, which is a facility on site, has changed to an abnormal state in appearance, at a management base away from the site, There is an excellent effect that the state of the facility can be easily detected while suppressing the cost and power consumption.

(2) In the equipment abnormality detection system described in (1), the storage battery is discharged from the fully charged state, and is charged again from the state of the amount of electricity before reaching the end voltage. Since it is a secondary battery having cycle use characteristics that are used repeatedly, the secondary battery having cycle use characteristics is discharged from a fully charged state and then fully charged by charging. The charge / discharge cycle to be returned to the battery can be used more frequently than, for example, a storage battery having a float use characteristic that is always used in a fully charged state, such as an automobile battery. Lifespan can be relatively long. Such a secondary battery, in particular, can ensure stable power over a long period of time, even when the charge / discharge cycle is repeated, since the decrease in electric capacity is relatively gradual in terms of battery performance.

(3) In the equipment abnormality detection system described in (1) or (2), while automatically controlling the charging voltage charged to the storage battery through the photovoltaic power generation panel, in the state where the storage battery has become low voltage, Since charging / discharging control means for automatically interrupting discharge is provided, it is possible to prevent the electric power generated by the photovoltaic power generation panel from being overcharged and stored in the storage battery, and the electric power is It is possible to prevent over-discharge from the storage battery, and to suppress the electrical burden on the storage battery. In addition, the storage battery can maintain a state of being stored with a stable electric capacity that does not hinder power consumed by the camera or the like.

(4) In the equipment abnormality detection system described in (3), the charge / discharge control means has a backflow prevention function for preventing current from flowing from the storage battery toward the photovoltaic power generation panel. Due to the reverse current, the reverse current prevention function prevents the reverse current from flowing from the storage battery to the solar power generation panel when the solar power generation panel is not generating power at night or in low light conditions such as rainy weather. Damage to the solar power generation panel. Moreover, waste of electric power stored in the storage battery can be prevented by the reverse current.

(5) In the equipment abnormality detection system according to any one of (1) to (4), a function confirmation server is provided separately from the server, and the function confirmation server outputs a timer start signal by a signal input / output means. The second instruction signal for output is provided so that it can be transmitted to the Internet connection transmission / reception means, and the function confirmation server is detected under the control of the power consumption control means based on the input timer start signal. Since the object is photographed with a camera and the image or image of the object to be detected transmitted simultaneously with the photographing by the Internet connection transmission / reception means is provided so as to be stored, the function confirmation server By transmitting the second instruction signal to the Internet connection transmission / reception means, for example, once a day at a regular frequency every day, the camera, Internet Whether the equipment such as connection / reception means is functioning and operating normally, and whether the video of the detected object can be properly transmitted to the management terminal at the management site. It can be judged.

(6) In the equipment abnormality detection system according to any one of (1) to (5), the equipment abnormality detection system includes an illuminating lamp that projects light on an object to be detected at the time of photographing with a camera. Switch on / off the power to the lamp according to the on / off of the power to the camera, the camera is a network camera that captures moving images or still images, and the object to be detected captured by the camera The video or image is transmitted at the same time as shooting by the Internet connection transmission / reception means, and can be disclosed at the management terminal of the management base. Even in such a case, the state of the object to be detected is clearly displayed as a clear image or clearly as a clear image by the network camera. As a result, the situation at the site where the object to be detected is present can be easily discriminated at the management base by being disclosed to the management terminal in real time all day, to the management terminal using the server together, or to both the management terminal and the server. . In particular, since the equipment abnormality detection system of the present invention is a system that performs imaging of an object to be detected at a preset time, for example, the imaging time per time is 3 minutes, and the number of times of imaging per day is 3. It is suitable for a site where it is sufficient to shoot intermittently in a short time to determine the state of the object to be detected, such as 8 times every time. In addition, even when the camera takes a picture and the illuminating lamp is lit, the power consumption control means suppresses the power consumed by the camera and the illuminating lamp. Because the storage battery can be charged within this time, the power supplied from the power source to the Internet connection transmission / reception means, the signal input / output means, the network camera, and the illuminating lamp is secured sufficiently stably. ing.

(7) In the equipment abnormality detection system according to any one of (1) to (6), the object to be detected is a conduit laid on a erection means laid on the ground. So, for example, the conduit may be destroyed by natural disasters such as local heavy rains, tornadoes, earthquakes and accompanying tsunamis, and may not function properly due to damage. Whether the state has changed to an abnormal state can be managed and discriminated for maintenance at a management base away from the site. Also, the conduit has not lost its function, is not in a dangerous state, or is suspicious due to, for example, intentional mischief of a malicious intruder, accidental damage to the conduit by a contractor, etc. It can be managed and discriminated for safety reasons at a management base remote from the site.

  By the way, when a conduit is laid across a river in a public facility that becomes a lifeline, such as a gas conduit that sends fuel gas, a tap water conduit that flows clean water, etc., for example, a bridge girder, Pipe exposure sites where pipes are laid on pipe beams and the like are scattered at a plurality of locations over a wide area in each region. Even with one such conduit exposure site, it is not possible to sufficiently detect the conduit across the river with a single visual field, and it is necessary to detect from multiple visual fields, which would increase the installation cost. . On the other hand, the facility abnormality detection system according to the present invention is easy to install at a conduit exposure site where the conduit is laid on a bridge girder, pipe beam or the like (erection means), and the construction cost is low. For this reason, the facility abnormality detection system of the present invention can be installed at a plurality of locations on the conduit exposure site at a low cost, and, as exemplified above, mischief of malicious intruders and inadvertent conduits by construction contractors. The system is able to meet the cost demands of each region that is trying to promote the monitoring of conduits in case of accidents caused by damage or natural disasters.

System.

  In the present embodiment, since the management terminal 41 installed at the management base 40 is separate from the server terminal 51 having the function of the function confirmation server 50F, the first instruction signal transmitted from the management terminal 41 is used. Sg1 and the second instruction signal Sg2 transmitted from the server terminal 51 are different from each other, but are substantially the same instruction signal.

  The power supply unit 10, the detection unit 20, and the illuminating lamp 30 are installed in the bridge gate structure 71, and the connection of the electrical wiring and the communication cable is completed between the devices, and the management terminal 41 and the mobile router 23 of the equipment abnormality detection system 1 However, it can be connected to the Internet via the server 50G. First, the case where the equipment abnormality detection system 1 is operated by the management terminal 41 to detect whether the conduit 60 or the like is in an abnormal state in the straddling area 75C will be described with reference to FIG.

  First, in the standby state of the equipment abnormality detection system 1 (step S1), the photovoltaic power generation panel 12 generates power, and the generated power is stored in the storage battery 13 while the charge / discharge controller 14 automatically controls the charging voltage. Is in a state. On the other hand, the storage battery 13 supplies power through the power consumption control unit 25 and is always energized to the mobile router 23 and the LANHUB 26. The I / O unit 24 is also energized.

  Next, when the management site 40 tries to detect the state of the conduit 60 and the like in the conduit exposure site 75, the administrator at the management site 40 performs a predetermined operation on the management terminal 41 to display the ID on the detection Web. And the IP address, the server 50G is accessed, and the first instruction signal Sg1 is transmitted from the management terminal 41 to the mobile router 23. The transmission of the first instruction signal Sg1 is performed intermittently in accordance with the timing at which the state of the conduit 60 and the like is to be confirmed, such as the frequency of 8 times every 3 hours per day. In step S2, if the mobile router 23 receives the first instruction signal Sg1 (YES), the process proceeds to step S3. If the first instruction signal Sg1 is not received, the mobile router 23 waits until it is received. (NO).

  Next, by receiving the first instruction signal Sg1, the mobile router 23 is connected to the management terminal 41 via the server 50G via the Internet. Then, the I / O unit 24 outputs a timer activation signal Sgt to the power consumption control unit 25 based on the first instruction signal Sg1 input to the mobile router 23 (step S3).

  Next, the timer activation signal Sgt is input to the power consumption control unit 25, and the power consumption control unit 25 starts energization timer control (step S4). Thereby, the power consumption control part 25 turns off the electricity supply from the storage battery 13 to the I / O unit 24 (step S5). At the same time, the energization from the storage battery 13 to the camera 22 is turned on so that photographing can be performed, and the energization from the storage battery 13 to the illumination lamp 30 is turned on to turn on the illumination lamp 30 (step S6). ).

  Next, in step S7, the camera 22 starts photographing a subject within a preset photographing range (a state of the conduit 60 and the like located in the straddling area 75C). The shooting time by the camera 22 is 3 minutes in this embodiment. The video signal Sgv of the video shot by the camera 22 is transmitted from the mobile router 23 to the management terminal 41 via the server 50G while shooting, and is disclosed in real time on the monitor of the management terminal 41 (step S8). In addition, the image | video which the camera 22 (camera 22 shown in FIG.3 and FIG.4) of the detection part 20 installed in the bridge gate 71 image | photographed the back | inner side (shown in FIG. 1) from the camera 22 in FIG. The field of view on the second area 75 </ b> B side) is displayed on the monitor of the management terminal 41 as the shooting range.

  Next, in step S9, the shooting is immediately terminated when 3 minutes have elapsed after the start of shooting, and the process proceeds to step S10. If it is still less than 3 minutes, shooting continues as it is until 3 minutes have passed (NO).

  Next, in step S10, after the time of 3 minutes has elapsed, the power consumption control unit 25 turns off the power supply to the camera 22 and the illumination lamp 30, and simultaneously supplies power from the storage battery 13 to the I / O unit 24. Turn back on. In step S11, communication via the Internet connection is disconnected between the mobile router 23 and the management terminal 41. Next, in step S12, if energization to the I / O unit 24 is switched to the on state in step S10, the process proceeds to step S1, and the first instruction signal Sg1 is transmitted from the mobile router 23 in preparation for the next shooting. Wait until it is received (YES). On the other hand, if the energization to the I / O unit 24 is not switched to the on state, the equipment abnormality detection system 1 considers that some abnormality has occurred, and the equipment abnormality detection system 1 is inspected.

  Next, in the case where the equipment abnormality detection system 1 is operated by the server terminal 51 to check whether or not the equipment abnormality detection system 1 is functioning normally at the conduit exposure site 75, it is the same as the description of the operation of the equipment abnormality detection system 1 described above. The facility abnormality detection system 1 that detects the straddling area 75C will be described with reference to FIG. FIG. 10 is a flowchart illustrating a case where the operation of the equipment abnormality detection system is performed by operating from the server terminal.

  In the equipment abnormality detection system 1, the server terminal 51 and the mobile router 23 of the equipment abnormality detection system 1 are in a state where they can be connected to the Internet via the server 50G.

  First, in the standby state of the equipment abnormality detection system 1 (step S21), the photovoltaic power generation panel 12 generates power, and the generated power is stored in the storage battery 13 while the charge / discharge controller 14 automatically controls the charging voltage. It is in a state. On the other hand, the storage battery 13 supplies power through the power consumption control unit 25 and is always energized to the mobile router 23 and the LANHUB 26. The I / O unit 24 is also energized.

  Next, when the server terminal 51 is to check whether there is any trouble between the equipment abnormality detection system 1 installed at the conduit exposure site 75 and the management terminal 41, the operator of the server terminal 51 The server terminal 51 performs a predetermined operation, inputs the ID and IP address to the detection Web, accesses the server 50G, and transmits the second instruction signal Sg2 from the server terminal 51 to the mobile router 23. . The transmission of the second instruction signal Sg2 is usually performed in accordance with the timing at which it is desired to check whether the equipment abnormality detection system 1 has a problem when operated on the management terminal 41, such as once per day. In step S22, if the mobile router 23 receives the second instruction signal Sg2 (YES), the process proceeds to step S23. If the second instruction signal Sg2 is not received, the mobile router 23 waits until it is received. (NO).

  Next, by receiving the second instruction signal Sg2, the mobile router 23 is connected to the server terminal 51 via the server 50G via the Internet. Then, the I / O unit 24 outputs a timer activation signal Sgt to the power consumption control unit 25 based on the second instruction signal Sg2 input to the mobile router 23 (step S23).

  Next, the timer activation signal Sgt is input to the power consumption control unit 25, and the power consumption control unit 25 starts energization timer control (step S24). Thereby, the power consumption control part 25 turns off the electricity supply from the storage battery 13 to the I / O unit 24 (step S25). At the same time, the energization from the storage battery 13 to the camera 22 is turned on so that photographing can be performed, and the energization from the storage battery 13 to the illumination lamp 30 is turned on to turn on the illumination lamp 30 (step S26). ).

  Next, in step S27, the camera 22 starts photographing a subject in a preset photographing range (a state of the conduit 60 and the like located in the straddling area 75C). The shooting time by the camera 22 is 3 minutes in this embodiment. The video signal Sgv of the video shot by the camera 22 is transmitted from the mobile router 23 to the server terminal 51 via the server 50G while shooting (step S28). Then, the server terminal 51 receives the video taken by the camera 22 in real time, and this video is stored in the function confirmation server 50F (step S29). The video from the camera 22 can also be projected in real time on the monitor of the server terminal 51. At this time, the operator of the server terminal 51 sees the video showing the state of the conduit 60 and the like, and the conduit 60 and the like. You can also check if there is any abnormality. Alternatively, it is detected that there is a possibility that a malfunction has occurred in the equipment abnormality detection system 1 when the operation is normally performed on the management terminal 41 due to the case where the video of the conduit 60 or the like is not stored in the server terminal 51. You can also

  Next, in step S30, the shooting is immediately terminated when 3 minutes have elapsed after the start of shooting, and the process proceeds to step S31. If it is still less than 3 minutes, shooting continues as it is until 3 minutes have passed (NO).

  Next, in step S31, after the time of 3 minutes has elapsed, the power consumption control unit 25 turns off the power supply to the camera 22 and the illuminating lamp 30, and simultaneously supplies power from the storage battery 13 to the I / O unit 24. Turn back on. In step S32, communication via the Internet connection is disconnected between the mobile router 23 and the server terminal 51. Next, in step S33, if the energization of the I / O unit 24 is switched to the on state in step S31, the process proceeds to step S21, and the equipment abnormality occurs when the normal management terminal 41 is operated at the next opportunity. In preparation for checking whether or not the detection system 1 has a problem, the mobile station 23 waits until the second instruction signal Sg2 is received (YES). On the other hand, if the energization to the I / O unit 24 is not switched to the on state, the equipment abnormality detection system 1 considers that some abnormality has occurred, and the equipment abnormality detection system 1 is inspected.

  The operation and effect of the equipment abnormality detection system 1 according to this embodiment having the above-described configuration will be described.

In the equipment abnormality detection system 1 according to the present embodiment, an image captured by the camera 22 can be transmitted to the management base 40 by the Internet INT connected via the power source, the camera 22, and the server 50G. 40, the mobile router 23 capable of receiving the first instruction signal Sg1, and the conduit 60 (object to be detected) at the conduit exposure site 75 away from the management base 40 is in an abnormal state. In the equipment abnormality detection system 1 for transferring the image of the subject such as the conduit 60 to the management terminal 41 installed in the management base 40 for the determination at the management base 40, the power is generated by the solar power generation panel 12. Based on the storage battery 13 storing electric power and the first instruction signal Sg1 input through the mobile router 23, the timer start signal Sgt. While the output I / O unit 24 and the mobile router 23 are always in an operating state, the energization from the storage battery 13 to the I / O unit 24 is turned off by the timer start signal Sgt input from the I / O unit 24. At the same time, the energization from the storage battery 13 to the camera 22 is switched on, and a subject such as the conduit 60 is photographed by the camera 22 for a preset time, and the video is managed by the mobile router 23 (management terminal 41 (server terminal 51)). ) And after the time is up, the power supply to the camera 22 is turned off, and at the same time, the power supply from the storage battery 13 to the I / O unit 24 is turned back on, and the communication (Internet communication) by the mobile router 23 is disconnected. And a power consumption control unit 25 that performs energization timer control. In the case of the pipeline 60 that is a lifeline, such as a gas conduit that feeds fuel gas and a tap water conduit that feeds clean water, as well as the state, in addition to the area that crosses the river, it is restricted by topographical conditions and building location conditions Thus, there is a conduit exposure site 75 in which the conduit 60 is laid on a bridge girder 70 laid on the ground GL. The facility abnormality detection system 1 according to the present embodiment has, as the preset time, for example, 3 times for the shooting time per time, 8 times for the number of shooting times per day, etc. For maintenance, it is possible to provide a system suitable for such a site that only needs to be able to shoot intermittently and in a short time to determine the state of the conduit 60 and its surroundings.

  That is, since the facility abnormality detection system 1 uses the storage battery 13 that stores the power generated by solar power generation as a power source, in particular, due to natural disasters such as heavy rains, tornadoes, earthquakes, and accompanying tsunamis, the site (conduit) Even when a power failure occurs at the exposure site 75), it is a premise that the power loss of the equipment abnormality detection system 1 can be avoided. After that, when the mobile router 23 receives the first instruction signal Sg1 from the management base 40 side, the mobile router 23 waits for the first instruction signal Sg1 so that the video of the conduit 60 and the like can be transmitted to the management terminal 41 of the management base 40. While the mobile router 23 with relatively low power consumption is always in an operating state, the power consumption control unit 25 does not need to maintain the operating state for the camera 22, the I / O unit 24, etc. Under circumstances, the energization is turned off to prevent unnecessary power consumption. As a result, in the conduit exposure site 75, the conduit 60 is intentionally damaged by a natural disaster caused by heavy rain, a tornado, an earthquake or a tsunami accompanying it, or a malicious intruder's mischief, etc. In the facility abnormality detection system 1, it is possible to suppress less power consumption and to ensure a stable supply of power in order to determine whether the management base 40 has been damaged or damaged due to an accident or the like. ing. As a result, it is not necessary to store large-capacity electric power generated using a larger photovoltaic power generation panel in a larger storage battery, and the photovoltaic power generation panel and storage battery can be installed in a small space and the power supply can be made compact. Therefore, the degree of freedom with which the equipment abnormality detection system 1 can be installed at the conduit exposure site 75 becomes greater.

  In addition, the equipment abnormality detection system 1 captures a subject such as the conduit 60 with the camera 22 for a preset time, and transmits the image of the conduit 60 or the like to the management terminal 41 as it is using the mobile router 23. For this reason, the facility abnormality detection system 1 includes a technique of Patent Document 2 configured with a multi-functional system such as a memory for temporarily storing captured images and the like, and a timing for transmitting the images to the server. In contrast, since the number of parts can be further reduced, the manufacturing cost can be reduced. In particular, the equipment abnormality detection system 1 is the minimum necessary to be able to shoot the conduit 60 and the vicinity thereof in a short time and intermittently in order to determine the state of the conduit 60 and the like for security and maintenance. Therefore, the entire system can be reduced in size. Therefore, as described above, the degree of freedom of the place where the equipment abnormality detection system 1 can be installed is greater and can be easily installed. In addition, when the installation place is changed, the equipment abnormality detection system 1 can be easily moved. Can be.

  Moreover, since it is not necessary to select the specifications for the large-capacity electric power for the above-described solar power generation panel 12 and the storage battery 13, the initial cost applied to the power source is low. Further, the wireless communication when the mobile router 23 receives the first instruction signal Sg1 from the management base 40 side, and the wireless communication when the mobile router 23 transmits the image of the conduit 60 or the like to the management terminal 41 are used for this communication. In the embodiment, since a high-speed mobile communication medium using a communication technology such as mobile WiMAX is used, it is possible to suppress a running cost for wireless communication. Moreover, if the camera 22 is a network camera and the mobile WiMAX exemplified above is used, the video of the conduit 60 and the like can be transmitted with high resolution image quality by high-speed communication such as mobile WiMAX. The image of the conduit 60 received by the management terminal 41 in the management base 40 is clear. Therefore, an administrator at the management base 40 away from the conduit exposure site 75 can quickly and clearly easily determine whether the conduit 60 at the site has changed to an abnormal state in appearance. it can.

  Therefore, according to the facility abnormality detection system 1 of the present embodiment, whether or not the conduit 60 that is a site facility has changed to an abnormal state in appearance is determined at the management base 40 away from the conduit exposure site 75. In the determination, there is an excellent effect that the cost and power consumption can be suppressed and the state of the facility can be easily detected.

  In addition, in the facility abnormality detection system 1 according to the present embodiment, the storage battery 13 is discharged from the fully charged state, and charged from the state of the amount of electricity before reaching the end voltage, so that the fully charged state is obtained again. Since it is a secondary battery having cycle use characteristics that are used repeatedly, the secondary battery having cycle use characteristics is discharged from a fully charged state and then fully charged by charging. The charge / discharge cycle to be returned to the battery can be used more frequently than, for example, a storage battery having a float use characteristic that is always used in a fully charged state, such as an automobile battery. Lifespan can be relatively long. Such a secondary battery, in particular, can ensure stable power over a long period of time, even when the charge / discharge cycle is repeated, since the decrease in electric capacity is relatively gradual in terms of battery performance.

  Moreover, in the equipment abnormality detection system 1 which concerns on this embodiment, while controlling the charging voltage charged to the storage battery 13 through the solar power generation panel 12 automatically, in the state in which the storage battery 13 became low voltage, discharge of the storage battery 13 is carried out. Since the charge / discharge control controller 14 that automatically shuts off the power is provided, it is possible to prevent the electric power generated by the photovoltaic power generation panel 12 from being overcharged and stored in the storage battery 13, and It is possible to prevent the electric power from being consumed by overdischarge from the storage battery 13 and to suppress the electrical load applied to the storage battery 13. Moreover, the storage battery 13 can maintain the state of being stored with a stable electric capacity that does not hinder the power consumed by the camera 22 or the like.

  Moreover, in the equipment abnormality detection system 1 which concerns on this embodiment, the charging / discharging control controller 14 has a backflow prevention function which blocks | prevents that an electric current flows toward the photovoltaic power generation panel 12 from the storage battery 13, It is characterized by the above-mentioned. Therefore, when the solar power generation panel 12 is not generating power at night or in low illumination such as rainy weather, the reverse current prevention function prevents the generation of reverse current from the storage battery 13 toward the solar power generation panel 12, and the reverse Damage to the photovoltaic power generation panel 12 due to the directional current can be prevented. Moreover, waste of electric power stored in the storage battery can be prevented by the reverse current.

  In addition, the equipment abnormality detection system 1 according to the present embodiment includes a function confirmation server 50F separately from the server 50G, and the function confirmation server 50F outputs a timer start signal Sgt by the I / O unit 24. 2 that the instruction signal Sg2 is provided so as to be transmitted to the mobile router 23, the function confirmation server 50F is controlled by the power consumption control unit 25 based on the input timer activation signal Sgt. Since the subject is photographed with the camera 22 and the mobile router 23 is provided so as to be able to store the image of the conduit 60 or the like transmitted simultaneously with the photographing, the second instruction is sent from the function confirmation server 50F. By transmitting the signal Sg2 to the mobile router 23, for example, once a day at a regular frequency every day, the camera at the conduit exposure site 75 is transmitted. 22, the equipment such as the mobile router 23 can be confirmed to function normally and operate, and the video of the conduit 60 can be appropriately transmitted to the management terminal 41 of the management base 40. Can be determined.

  In addition, the equipment abnormality detection system 1 according to the present embodiment includes the illuminating lamp 30 that projects light onto the conduit 60 or the like when photographing with the camera 22, and the power consumption control unit 25 turns on / off energization of the illuminating lamp 30. Switching off according to on / off of energization to the camera 22, the camera 22 is a network camera that shoots moving images, and the video of the conduit 60 or the like that is captured by the camera 22 is transmitted by the mobile router 23. Since it is transmitted at the same time as photographing and can be disclosed by the management terminal 41 of the management base 40, the state of the conduit 60, etc. Is clearly displayed by the network camera 22 as a clear image. As a result, the situation of the conduit exposure site 75 where the conduit 60 is located is changed to the management terminal 41 in real time all day, to the server terminal 51 used together with the management terminal 41, or to the server terminal 51 of the management terminal 41 and the function confirmation server 50F. And can be easily identified at the management base 40. In particular, since the equipment abnormality detection system 1 of the present embodiment is a system that performs imaging of the conduit 60 or the like at a preset time, for example, the imaging time per time is 3 minutes and the number of times of imaging per day is set. It is suitable for a site where it is sufficient to shoot intermittently in a short time to determine the state of the conduit 60 etc., such as 8 times every 3 hours. In addition, even when the camera 22 takes a picture and the illuminating lamp 30 is turned on, the power consumption control unit 25 suppresses the power consumed by the camera 22 and the illuminating lamp 30. Since the storage battery 13 can be charged within the time between the shooting, the power supplied from the storage battery 13 to the mobile router 23, the I / O unit 24, the camera 22, and the illumination lamp 30 is Ensured, stable enough.

  Moreover, in the equipment abnormality detection system 1 according to the present embodiment, the object to be detected is the conduit 60 laid on the bridge girder 70 laid on the ground GL. Due to natural disasters such as local heavy rains, tornadoes, earthquakes and the accompanying tsunamis, it will be destroyed and will not function properly due to damage. It can be managed and discriminated for maintenance at the management base 40 remote from the site (conduit exposure site 75). In addition, the conduit 60 has not lost its function, is not in a dangerous state, or is suspicious due to, for example, intentional mischief of a malicious intruder or accidental damage to the conduit by a construction contractor. Whether a person has entered the conduit exposure site 75 where the conduit 60 is located or the like can be managed and discriminated for safety reasons at the management base 40 remote from the site.

  By the way, when the conduit 60 is laid across the river RV in a public facility such as a gas conduit for sending fuel gas or a tap water conduit for flowing clean water, the conduit 60 is connected to the bridge girder 70. The laid conduit exposure sites 75 are scattered at a plurality of locations over a wide area in each region. Even if one such conduit exposure site 75 is taken, the conduit 60 straddling the river RV cannot be detected sufficiently from one field of view, and it is necessary to detect from a plurality of fields of view. Become. On the other hand, the facility abnormality detection system 1 of the present embodiment is easy to install on the conduit exposure site 75 where the conduit 60 is laid on the bridge girder 70, and the construction cost is low. Therefore, the equipment abnormality detection system 1 can be installed at a plurality of locations of the conduit exposure site 75 at a low cost, and as exemplified above, a malicious intruder mischief or accidental damage to a conduit by a construction contractor. In preparation for unforeseen circumstances due to accidents and natural disasters, it is a system that can meet the cost demands of each region that is promoting the monitoring of the conduit 60.

  In the above, the present invention has been described with reference to the embodiments. However, the present invention is not limited to the above-described embodiments, and can be appropriately modified and applied without departing from the gist thereof.

(1) For example, as described in the embodiment, in the embodiment, the management terminal 41 installed in the management base 40 and the server terminal 51 having the function of the function confirmation server 50F are respectively separate terminals. However, the management terminal 41 may be the server terminal 51 having the function of the function confirmation server 50F. In this case, as described in the embodiment, the management terminal 41 shoots the conduit exposure site 75 with the camera 22 in a short time and intermittently, and captures the situation of the conduit 60 and its surroundings at the management base 40. In addition to the functions that can be discriminated, it is only necessary to confirm whether the camera 22 is operating normally by the second instruction signal Sg2 transmitted from the function confirmation server 50F.
(2) In the embodiment, the facility abnormality detection system 1 is installed at the conduit exposure site 75, and the camera 22 directly photographs the state of the conduit 60 laid on the bridge girder 70. You may attach a mark to clarify. An example is shown in FIG. FIG. 12 is a diagram for explaining how to use the equipment abnormality detection system, and is a plan view of the conduit exposure site as seen from above, as in FIG. 2. As shown in FIG. 12, a strip-shaped marker 61 that reflects light is attached to the conduit 60 along the longitudinal direction of the conduit 60 that straddles the first area 75A and the second area 75B. In particular, if it is sufficient to make a rough judgment as to whether or not the conduit 60 is damaged due to a natural disaster or the like, the camera 22 is provided with a high-quality high-performance camera, the illumination lamp 30 is provided with a conduit exposure site 75. There is no need to use an illuminating lamp that can project a large amount of light. Therefore, since the manager of the management terminal 41 and the operator of the server terminal 51 can determine the state of the conduit 60 by looking at the state (position and shape) of the marker 61 reflected in the video by the camera 22, the marker 61. If it is used in combination with this, the cost of the equipment abnormality detection system 1 can be further reduced.

(3) Further, in the embodiment, the detected object is a video obtained by capturing a moving image, but an image obtained by capturing the detected object as a still image may be used.
(4) In the embodiment, the bridge girder 70 has been described as an example of the erection unit. However, the erection unit is not limited to the bridge girder 70 and may be at least two points separated from each other on the ground such as a pipe beam. As long as it is a facility that spans and connects between the two, the conduit (object to be detected) can be maintained between the at least two points and supported above the ground.
