Description

The present invention relates to a manhole information management system, a manhole information management method, and a manhole information management program for managing manhole information.

Manholes are installed on sidewalks. A manhole is a vertical hole in the ground that allows workers to enter and exit from the ground for the purpose of managing underground sewers and communication cables.

These manholes, culverts, rainwater discharge chambers, etc. constitute pipeline facilities. Pipeline facilities are regularly inspected, surveyed, and repaired for the purpose of maintaining functionality and maintaining a certain level of service. Therefore, manholes also need regular inspection. This is because if left unattended, the manhole will deteriorate over time, and the concrete wall of the manhole will corrode and deteriorate. Specifically, once every few years (for example, five years), the state of deterioration of manholes is inspected, and those in need (those with severe deterioration) are repaired.

Therefore, it is necessary to appropriately manage manhole information. Here, Patent Documents 1 and 2 disclose techniques for managing manhole information.

Patent Literature 1 describes a management method and a management system in which a manager manages manhole information by operating a mobile computer using storage means provided in the manhole. For example, in Cited Document 1, as a method of managing manhole information, a storage means capable of recording digital information is placed and fixed on the manhole, and the storage means contains drawing information related to the manhole, construction information that records the history of manhole construction, and It is described that at least one piece of stored equipment information relating to the equipment housed in the manhole is recorded.

In addition, Patent Document 2 describes a technique for identifying manholes and managing related information using a mobile computer equipped with a GPS device. For example, in Patent Document 2, one or more pieces of manhole information selected from drawing information about manholes, construction information recording the history of manhole construction, and information about equipment housed in manholes are recorded. A manhole consisting of a database, an electronic map storage means that stores an electronic map including the manhole installed position, and an electronic terminal device equipped with a manhole position specifying function for specifying the manhole installed position. A manhole information management method for an information management system is described in which the positions of manholes are specified on the electronic map, the manhole information is retrieved from a database, and displayed on a display device of an electronic device terminal.

[server]
The server 10 is a storage device that stores manhole information, worker information, and the like. The server 10 may be of a cloud type or of an on-premise type.

The manhole information includes an identification number assigned to each manhole, dimensions (manhole dimensions), depth at the bottom of the inclined wall, number of pipes, and the like. It also includes information (location information) such as the system number, planar rectangular coordinate system, and the latitude and longitude of the place where the manhole is installed. In addition, there are no particular restrictions as long as the information is related to manholes.

The number of pipes is the number of pipes provided in the manhole. The manhole information includes the number of pipes and the types of pipes. The type of pipe is, for example, an outflow pipe or an inflow pipe. In addition, as detailed information on pipes, information such as pipe diameter, pipe top height, inflow angle, presence or absence of sub pipes, sub pipe top height, etc. is also included as manhole information.

On the other hand, manhole information is associated with construction information. The construction information includes a construction name (project name) and a construction number (identification number) assigned for the convenience of inspecting manholes in a certain area. For example, names such as "○○ town survey" and "○○ area inspection" are given as construction names.

Also, a plurality of manholes may be subject to inspection in one construction (inspection). In this case, a plurality of pieces of manhole information are associated with one construction work. For example, manhole No. 1, manhole No. 2, . be done.

The construction information includes the orderer, contractor, measurement person, date of measurement, construction period (date of start and date of completion), and the like. In addition, information such as construction site and construction area is also included.

[Terminal]
FIG. 2 is a schematic configuration diagram of a terminal according to an embodiment of the present invention. The terminal 20 has communication means 21 , control means 22 , display means 23 , storage means 24 , photographing means 25 , editing means 26 and transmission means 27 . The terminal 20 implements a function of acquiring and registering manhole information using each of these means.

The communication means 21 is a function for communicating with an external device or system. For example, it is a function of communicating with the server 10 by wire or wirelessly via the network communication network N. FIG.

The control means 22 has a function of performing processing for various controls such as distribution processing of received messages (telegrams) and arithmetic processing.

The display unit 23 has a function of displaying an arbitrary screen on the display unit (display) of the terminal 20 described above. 3 to 7 are diagrams for explaining operation screens of the terminal according to the embodiment of the present invention. These screens are created and displayed by the display means 23. FIG.

The storage means 24 has a function of storing (saving) the manhole information management program of the present invention, and storing various configurations and various data. The manhole information registered by the operator H operating the terminal 20 is also stored in the storage means 24 . The storage unit 24 can be implemented by a storage medium such as flash memory, HDD, SSD, or the like.

The photographing means 25 is a function for photographing a manhole or the like. The photographing means 25 can be implemented by, for example, a camera attached to a smartphone or the like. Further, the photographing means 25 displays marks (frame lines, arrows, characters, descriptions, icons, etc.) for assisting the worker H in photographing on the photographing screen.

The editing means 26 has a function of editing the image photographed by the photographing means 25 .

The transmission means 27 has a function of transmitting the manhole information stored in the storage means 24 to the server 10 when the worker H operates the terminal 20 .

[Manhole information management method]
Hereinafter, a manhole information management method using the manhole information management system of the present invention will be described with reference to each drawing. First, the worker H carries the terminal 20 and goes to the manhole M to be inspected. Then, the manhole M is inspected, and various information about the manhole M is registered (obtained) using the terminal 20 .

3 to 8 are diagrams for explaining operation screens of the terminal according to the embodiment of the present invention. Here, it is assumed that the terminal 20 is installed with a manhole information management program for realizing the function of registering manhole information. Then, the installed program can be used as an application. It is assumed that the terminal 20 has a touch panel as an input unit.

FIG. 3A is an example of a screen after starting this application and logging in. FIG. Worker H activates the application, enters his account (e.g., e-mail address) and password, and performs login processing. Such a login process is realized by the control means 22 collating the input information with the worker information stored in the server 10 .
Then, the worker H selects a desired menu (function) from this screen. For example, when the "data input" button is selected (depressed), the screen transitions to a screen showing a list of construction works (survey object list screen) as shown in FIG. 3(B1) or FIG. 3(B2).

If no construction (surveyed object) information linked to the logged-in worker is registered in the server 10, nothing is displayed as shown in FIG. 3B1. On the other hand, if there is registered construction information, the information is displayed as shown in FIG. 3 (B2). Further, when the operator H swipes downward (in the direction of the dotted arrow in FIG. 3B2), the registered information is acquired from the server 10 and displayed one after another. In other words, the information (data) to be displayed is obtained from the server 10 in this way.

Various types of information stored in the server 10, such as construction information and manhole information, can be acquired at desired timing by requests sent automatically or manually from the terminal 20. FIG. For example, the terminal 20 transmits to the server 10 a request to acquire construction information linked to the identification number of the terminal 20 and the place (town, district) where the worker H works, through the control means 22, and the server 10 transmits the request to the terminal 20. Then, the terminal 20 causes the display means 23 to display the construction information included in the received response.

On the other hand, such communication can be appropriately changed in design depending on the usage pattern of the manhole information management system 1 . For example, communication between the terminal 20 and the server 10 occurs when the "Send" button is pressed on the survey property list screen (see FIG. 8C) and when the survey property list is swiped downward (see FIG. 3B2). ) can only be Otherwise, the information is displayed on the screen by referring to the data in the terminal 20 . Data in the terminal 20 is data stored in the storage means 24 of the terminal 20, for example.

This will allow you to use it even when you are offline. For example, even if the worker creates new data on the terminal 20, it cannot be sent to the server 10 if the worker is in a place where radio waves do not work or where radio wave conditions are poor. Therefore, by enabling transmission at an arbitrary timing later, it becomes possible to transmit data in the terminal 20 to the server 10 when the worker moves to a place with good radio waves.

Further, when the "setting" button in FIG. 3A is pressed, the screen changes to a setting screen as shown in FIG. 4A. When the "help" button in FIG. 3(A) is pressed, the screen changes to a help screen as shown in FIG. 4(B).

[Construction information registration]
Here, when the worker H wants to register new construction information, he presses the "new" button on the upper right of the survey object list screen shown in FIG. 3(B1) or FIG. 3(B2). Then, a transition is made to a construction information registration (input) screen as shown in FIG. 5(A). Then, the worker H inputs construction information on this screen.

After completing the input of the construction information, the worker H presses the "OK" button. If it does so, it will change to a manhole list screen as shown in FIG.5(B) this time. Again, if there is no registered manhole information, nothing is displayed as shown in FIG. 5B, and if there is registered manhole information, that information is displayed. The displayed manhole information is also acquired based on the exchange between the terminal 20 and the server 10 as described above.

[Manhole information registration]
Here, when the operator H wants to register new manhole information, he presses the "new" button on the upper right of the data input screen shown in FIG. 5(B). If it does so, it will change to the registration screen of manhole information as shown in FIG. 6(A). Then, the worker H inputs manhole information on this screen.

The manhole information includes an identification number assigned to each manhole, dimensions (manhole dimensions), and the like, as shown in FIG. 6(A) as an example. The worker H registers (inputs) information on manholes on this screen.

Also, the worker H inputs a manhole image by photographing the manhole with the photographing means 25 of the terminal 20 . FIG. 6B shows the screen after photographing the manhole and inputting the manhole image. The manhole can be photographed by activating the camera as the photographing means 25 by pressing the "manhole photographing" button shown in FIG. 6(A).

In addition, FIG. 6C is a screen when photographing a manhole. That is, when the "manhole photographing" button shown in FIG. 6(A) is pressed, the photographing screen as shown in FIG. 6(C) is displayed. Then, the operator H presses the "photograph" button at the timing when the manhole fits within the angle of view of the camera, thereby photographing the manhole. The photographed manhole image is stored (saved) in the storage means 24 of the terminal 20 (for example, the memory of the smartphone).

[guide]
Here, when photographing a manhole, a guide G is superimposed and displayed on the photographing screen. The guide G is, for example, a circular mark for clearly photographing a manhole. In other words, the manhole can be photographed neatly by photographing the manhole such that the manhole is accommodated inside the guide G or the outer frame of the manhole is along the frame line of the guide G.

Furthermore, the color and size of the guide G can be changed arbitrarily. For example, in the example shown in FIG. 6C, the display of the lower left button B1 is "zoom". When the display of the button B1 is "zoom", the camera can be zoomed by operating the screen of the terminal 20 (for example, pinching in or pinching out by moving two fingers on the screen as if pinching them together or opening them). can be zoomed in and out.

By operating (for example, tapping) the button B1, the display of the button B1 can be changed to "guide". When the display of the button B1 is "Guide", the focus and brightness of the camera can be adjusted by operating (for example, tapping) the shooting screen of the terminal 20. FIG. Also, by performing another operation (for example, double-tapping) on the shooting screen of the terminal 20, the color inside the guide G and the color of the line of the guide G can be optionally changed to white, black, yellow, red, green, blue, or the like. be able to.

When the display of the button B1 is "guide", the size (diameter) of the guide G can be changed by pinching in and out of the guide G superimposed on the photographing screen of the terminal 20. .

Such functions are realized by the control means 22 and the photographing means 25 . In addition, by changing the color of the guide G with such a function, even if the object to be photographed is too dark or, on the contrary, too bright, the worker H can easily see the object to be photographed, and a clear manhole image can be photographed. can do. In addition, since the size of the guide G can be changed by such a function, the worker H can take a clear image of a manhole of any size.
Since the manhole is not an ellipse but a perfect circle, the worker H can use the manhole regardless of the type by making the guide G a circular mark whose size can be changed.

When the manhole is photographed, the screen transitions to an editing screen for editing by adding a mark to the position of the pipe provided in the photographed manhole, as shown in FIG. 7B. On this screen, the worker H adds a mark to the position of the pipe on the photographed manhole image, and edits the manhole image. Such functions are implemented by the editing means 26 . In the following description, it is assumed that the number of pipes provided in the photographed manhole is three.

In the example shown in FIG. 7, the captured manhole image is edited by adding a line segment extending from the center point of the manhole to the location of the pipe (see FIG. 7B). For example, the worker H rotates a line segment extending from the mark (o) indicating the center point of the manhole to the position of the pipe with the mark (o) as an axis.
The length of the line segment can be arbitrarily changed by the operator H's operation (for example, dragging the tip of the line segment).

Here, as shown in the lower part of FIG. 7B, the angle between the first pipe and the second pipe is displayed. In the example shown in FIG. 7B, the angle between the first pipe and the second pipe is 60 degrees. Then, the first pipe and the second pipe can be rotated around the mark (○) indicating the central point of the manhole to the position of each pipe.

In other words, the line segments indicating the positions of the first pipe and the second pipe can be rotated clockwise/counterclockwise by an operation such as dragging. When the line segment of the second pipe is rotated, the function of the editing means 26 recalculates and displays the angle between the first pipe and the second pipe each time. Therefore, the operator H can grasp the angle between the second pipe and the first pipe in real time while rotating the line segment of the second pipe.

Note that FIG. 7C is a diagram in which a mark is added to the position of the third pipe, as with the first and second pipes. Since the manhole photographed in this description has three pipes, the worker H presses the "add pipe" button to mark the position of the third pipe on the manhole image.
Also, in this case, the editing means 26 determines the angle between the first pipe and the second pipe (60 degrees in the example shown in FIG. 7C) and the angle between the second pipe and the third pipe. The angle between (50 degrees in the example shown in FIG. 7(C)) is displayed. That is, the worker H can grasp the angles between the plurality of pipes in real time.

When the worker H edits the manhole image by adding marks up to the third pipe, he finally presses the "confirm" button to complete the editing. Then, the screen changes to the manhole information registration screen (FIG. 6B), and the "OK" button is further pressed to complete the registration of the manhole information. FIG. 8A is a manhole list screen after manhole information is registered. As shown in FIG. 8(A), the manhole size, the depth of the bottom of the inclined wall, the number of pipes, and the edited manhole image are registered.

Then, the worker H transmits the registered information to the server 10 using the transmitting means 27 of the terminal 20 . For example, when the "return" button shown in FIG. 8(A) is pressed, the screen transitions to a survey property list screen as shown in FIG. 8(C). Information can be sent by pressing a "send" button as shown in FIG. 8(C).

[option]
Adding a mark to the position of the pipe as described above is merely an example, and the color and thickness of the line segment attached to each pipe may be changed arbitrarily. Also, after the manhole is photographed by pressing the "shooting" button shown in FIG. 6A, two line segments as shown in FIG. You may start from the state where the line segment indicating the position of the second pipe) is displayed, and only one line segment (the line segment indicating the position of the first pipe) as shown in FIG. You can start from the state where is displayed.

By pressing the "photo selection" button shown in FIG. clean image) can be selected. When an image is selected, a transition is made to an edit screen as shown in FIG. 7(B).

Furthermore, by pressing the "Position Adjustment" button shown in FIG. 6A, it is possible to correct the content of the information that has been edited by pressing the "Confirm" button as described above.

In some cases, a plurality of manholes may be inspected in one construction. Therefore, it is possible to register a plurality of pieces of manhole information associated with one piece of construction information. FIG. 8B is a diagram showing an example in which three pieces of manhole information are registered. Of course, four or more pieces of manhole information can be registered for one piece of construction information, and the number of pipes can also be registered as four, five, and so on.

The number of pipes installed in manholes is as many as 5 or 6, which is difficult to manage with conventional technology. This is especially true in areas with complicated pipeline facilities, such as urban areas and downtown areas. However, according to the present invention, it is easy to register such pipe information, and it is possible to visually grasp the position (or direction) of the pipe based on the manhole image. Therefore, pipe information can be easily managed and effectively used.

Also, the layout of the screen, the arrangement of the buttons, the button names, etc. in FIGS.

[Edit/delete information]
As shown in FIG. 9, registered information can be edited and deleted. For example, as shown in FIG. 9(A), when the worker H operates (for example, swiping in the horizontal direction) an arbitrary construction site on the survey property list screen, the display means 23 displays an "edit" button. and a "delete" button. When the operator H presses "edit", the screen changes to the construction information registration screen shown in FIG. 5A, and the operator H can edit the construction information on the screen. can. On the other hand, when the worker H presses "delete", the construction information is deleted. However, each means of the terminal 20 can be appropriately restricted such that information that has already been transmitted to the server 10 cannot be deleted.

The same applies to the manhole information list screen shown in FIG. 9B. Registered manhole information can also be edited and deleted as appropriate. Also in this case, appropriate restriction processing can be provided such that information that has already been transmitted to the server 10 cannot be deleted.

[jig]
The manhole information management system 1 also includes a jig provided for each position of the manhole M pipe. This jig can be installed at each pipe position where the operator H enters the manhole M.

FIG. 10 is a diagram for explaining an example of a jig according to an embodiment of the invention. In this example, the jig J is made of plastic and has a circular shape (ring shape), and its diameter is slightly smaller than the inner diameter of the manhole M (see FIG. 10(A)).
Note that FIG. 10B is an enlarged view of the dotted frame portion shown in FIG. 10A. As shown in FIG. 10(B), the jig J is fixed (installed) on the wall surface of the manhole M with fasteners T such as a plurality of screws.

Moreover, as shown in FIG. 10B, the jig J includes a marker S provided for each position of the pipe. In this example, the marker S is movable along the outer periphery of the ring-shaped jig J and is fixed at the position of the pipe. The number of markers S is sufficient to correspond to the number of pipes provided in the manhole where the jig J is to be installed.

Examples of how to use the jig J include the following examples.
(1) The operator H descends into the manhole M with the jig J.
(2) Stop the descent at a place where all the pipes provided in the manhole M can be visually recognized, and install the jig J on the wall surface of the manhole M at that place.
(3) A marker S is fixed at the position of the pipe (the position of the jig J at the same height as the pipe).
(4) If there are a plurality of pipes, fix markers S at the positions of all the pipes.

As a result, when the operator H adds a mark to the position of the pipe provided in the photographed manhole and edits it, the marker S serves as a mark, and the position of the pipe is easy to understand. For example, when an operator H photographs a manhole, even if the manhole is photographed not from directly above but from a slightly oblique angle, the marker S is not hidden and the positions of all pipes in the manhole image can be clearly recognized.

Furthermore, by using jigs and markers that are brightly colored or that emit light, it is possible to inspect manholes regardless of the weather or time of day. For example, if the inspection day is cloudy or the inspection is done in the middle of the night, there is a risk that the photographed manhole image will be dim. However, by configuring the jigs and markers as described above, the inspection can be stably performed even in such a situation.

The embodiment of the present invention described above is merely an example, and the manhole information registered on the manhole information registration screen and the manhole information stored in the server can be appropriately used as long as they are necessary for inspection and management. can be added. Moreover, the jig J and the marker S are not limited to the above examples as long as the position of the pipe can be identified by the marker (mark).

INDUSTRIAL APPLICABILITY The present invention can manage information with greater convenience and can be used as a manhole information management system that is easier for workers to use. Therefore, it is industrially useful.
