Description

  The present invention relates to a field survey support technology.

  Site surveys are conducted for the construction, maintenance, and disaster recovery of various facilities. For example, in a sewerage facility, when a large-scale earthquake occurs, sewer pipes and manholes may be damaged, and the original function may be impaired. Therefore, after the occurrence of a large-scale earthquake, a site survey is conducted to go to the sewer laying site, check the status of pipes and manholes one by one, and grasp the current state of the facility. The sewer manager will formulate a facility recovery plan based on the results of this field survey.

  In the field survey of such sewerage facilities, conventionally, the investigator has performed visual confirmation and measurement on the site of each surveyed equipment (for example, a human hole), and recorded the survey results on paper. I was taking a photo. After that, the investigator brought the survey results back to the office and created a survey report by organizing information such as converting the survey results into electronic data and organizing the photos that correlate each survey subject with the photos taken.

  However, the conventional field survey method described above leaves room for improvement in terms of efficiency. For example, the number of facilities constituting the sewerage facility is enormous, and the work of digitizing the survey results of each survey subject puts a considerable burden on the investigators. In addition, the number of photos has become enormous in proportion to the number of facilities, and the photo organization work for associating each survey object with the taken photos has been a heavy burden. In particular, in the case where the above-described human hole is an object of investigation, there is almost no difference in appearance among a plurality of photographs taken of different human holes, and the photo organization work is complicated.

  Alternatively, the investigator sometimes had a hard time finding the subject of the survey because it was not always done by a person who is familiar with the local geography. In particular, when a large-scale earthquake occurs, investigators residing in areas other than the disaster-affected areas are often dispatched as disaster assistance, so this problem is remarkable.

  The above-described problems are not limited to sewerage facilities, but are common to various facilities such as waterworks facilities, railways, and roads. In addition, the survey was not limited to the current situation of facilities at the time of a disaster, but was common to field surveys for selecting various facilities, equipment maintenance, and planned construction sites. In addition to site surveys for geographically distributed facilities, management of construction records at construction sites, construction supervision for various structures, buildings, plants, etc. It was a problem common to various field surveys such as maintenance inspections after completion.

A-4. Survey result input process:
The investigation result input process in the field investigation support system 20 including the server 100 and the terminal 200 described above will be described. The survey result input process is a process of transmitting the result of the field survey from the terminal 200 to the server 100 and registering it in the server 100. The flow of the survey result input process is shown in FIG. As illustrated, in the survey result input process, first, the CPU 210 of the terminal 200 transmits a GUI data request to the terminal 200 as a process of the GUI acquisition unit 211 (step S310). In this embodiment, this processing is executed by the CPU 210 accessing a predetermined URL (Uniform Resource Locator) of the server 100 using the WEB browser based on the operation of the investigator who visited the investigation site.

  On the other hand, when the CPU 110 of the server 100 receives a GUI data request from the terminal 200, it transmits GUI (Graphical User Interface) 1 data stored in the hard disk drive 120 to the server 100 as processing of the GUI transmission unit 111 (step 100). 410). This GUI 1 is an initial screen for inputting a survey result using the terminal 200.

The search screen window W11 includes a search execution button B11, input windows IW11 to IW13, and a record addition button B12. When a human hole number is entered in the input window IW11 and the search execution button B11 is pressed, an investigation result input screen (hereinafter also referred to as GUI2) associated with the human hole number that matches the input number is displayed. . The GUI 2 will be described later. A plurality of human hole numbers may be entered in the input window IW11. Alternatively, a part of the human hole number may be input. For example, if the human hole number is a system such as 1-1, 1-2, 2-1, etc., if a search is performed by entering "1-", the human hole numbers 1-1, 1- For each of the items 2, a GUI 2 capable of inputting a survey result is displayed so as to be scrollable.

  Further, the search screen window W11 can display the GUI2 of the human hole number that matches the input condition by inputting the drawing number or the tube number into the input window IW12 or the input window IW13 and performing the search. In this case, for example, each entry in the survey target information table 121 may be associated with a drawing number or a management number for use in this search. The record addition button B <b> 12 is provided for creating a new entry in the investigation result table 122 by an operation on the terminal 200.

  The survey result output window W12 is provided to display the survey result on the display 250 of the terminal 200. The survey result output window W12 includes a list display button B13 and a layout diagram display button B14. When the list display button B13 is pressed, the survey results recorded in the survey result table 122 are listed and displayed on the display 250. When the layout diagram display button B14 is pressed, a layout diagram in which all positions of human holes to be investigated are dropped on the map is displayed on the display 250. In this embodiment, information based on the investigation result is also added to this layout diagram. Details of the layout diagram will be described later. The survey result output in the survey result output window W12 can be targeted only for human holes that meet the conditions. Specifically, when a search condition is input to any of the input windows IW11 to IW13 of the search screen window W11 and the list display button B13 or the layout diagram display button B14 is pressed, only human holes that match the search condition are displayed. The target survey results can be output.

  Here, the description returns to FIG. When receiving the GUI1 data, the CPU 210 of the terminal 200 displays the GUI1 on the display 250 (step S320). The investigator. For example, a desired human hole number is input using this GUI 1. The CPU 210 receives the input of the human hole number as the process of the reception unit 213, and transmits a GUI data request specifying the received human hole number to the terminal 200 as the process of the GUI acquisition unit 211 (step S330).

  On the other hand, in the server 100, when the GUI data request is received, the CPU 110 transmits the GUI2 data corresponding to the human hole number designated by the received GUI data request to the terminal 200 as a process of the GUI transmission unit 111 (step 200). S420). In the present embodiment, the designated human hole number is added to the GUI2 data. Further, when the survey result corresponding to the human hole number is already stored in the survey result table 122, the survey result is also added. The CPU 210 of the terminal 200 receives the GUI2 data, and displays the GUI2 on the display 250 as a process of the GUI display unit 212 (step S340).

  A specific example of GUI2 is shown in FIG. The GUI 2 is configured to be able to input a survey result on a human hole corresponding to the human hole number in association with the human hole number. Specifically, the GUI 2 includes a survey result input window W21, an input button B21, a photo button B22, a map display button B23, and a related drawing button B24. The survey result input window W21 includes a display window DW21 and an input window IW21. A human hole number is displayed in the display window DW21. This human hole number is the human hole number extracted by the search using GUI 1, that is, the human hole number designated in the GUI data request in step S 330. Information input through the GUI 2 is linked to the human hole number. In the present embodiment, the human hole number is displayed on the GUI 2 in order to improve the convenience. However, the fact that it is linked does not have to be clearly indicated on the GUI 2.

  In the input window IW21, whether or not there is an abnormality in the human hole corresponding to the human hole number displayed in the display window DW21 is input based on the field survey. Although a detailed description is omitted, other investigation items such as a pipe diameter and an extension can be input in the same manner as the input window IW21. These input windows are displayed blank for items that have not been investigated. On the other hand, when GUI2 is displayed for the surveyed human hole, each input window of GUI2 includes the human hole number displayed in the display window DW21 among the survey results stored in the survey result table 122 of the terminal 200. The survey results corresponding to are displayed. With such a configuration, the investigator can grasp at a glance whether or not the investigator has already been investigated or has been investigated by another person. In other words, duplication investigation due to errors can be avoided and efficiency is improved. The survey results can be input to these input windows by pressing the input button B21 to switch from the browsing mode to the input mode.

  The photograph button B22 is used when the camera 270 captures the scene situation. The map display button B23 is used when displaying a map indicating the position of the human hole corresponding to the human hole number displayed in the display window DW21. Details of the photo button B22 and the map display button B23 will be described later.

  The related drawing button B24 is used when browsing the design drawing of the human hole corresponding to the human hole number displayed in the display window DW21. The hard disk drive 120 stores a design drawing of each human hole in association with a human hole number. When the investigator presses the related drawing button B24, the CPU 210 transmits a design drawing request specifying the human hole number to the server 100. In response to this, the CPU 110 of the server 100 responds with a drawing corresponding to the designated human hole number. The CPU 210 receives this design drawing and displays it on the display 250. According to this configuration, it is possible to easily know the specifications of the human hole before the disaster, so that it is possible to more accurately determine whether there is an abnormality.

  Here, the description returns to FIG. When the CPU 210 of the terminal 200 displays the GUI 2 on the display 250, the receiving unit 213 receives an input of the survey result from the investigator via the GUI 2 as a process of the receiving unit 213 (step S350). When receiving the input, the CPU 210 automatically transmits the received survey result to the server 100 as a process of the survey result transmitting unit 214 (step S360). Even after transmission, the input information is displayed as it is in the input window. The survey result to be transmitted is associated with the human hole number displayed in the display window DW21. In this embodiment, every time an input is made in one input window using the GUI 2, the CPU 210 transmits the input result to the server 100 as needed. However, the configuration may be such that transmission is performed after receiving input from all input windows. Or it is good also as a structure which transmits after receiving a transmission instruction | indication.

  On the other hand, when receiving the survey result, in the terminal 200, the CPU 210 records the received survey result in an entry corresponding to the human hole number associated with the survey result in the survey result table 122 (step S430).

  Here, the photo button B22 will be described. Although not shown in FIG. 6, when the investigator presses the photograph button B <b> 22, the CPU 210 transmits the GUI data request to the server 100 by specifying the human hole number displayed in the display window DW <b> 21. At this time, the CPU 210 automatically activates the camera 270. The CPU 110 of the server 100 transmits the GUI3 data to the terminal 200 as a response to the GUI data request.

  A specific example of GUI 3 is shown in FIG. As illustrated, the GUI 3 includes a display window DW31 and input windows IW31 to IW34. In the display window DW31, the human hole number designated by the GUI data request is displayed. The input windows IW31 to IW34 are configured in the same format as the photo organization page in the survey report. Here, when the user selects and presses any of the input windows IW31 to IW34 and then takes a picture using the camera 270, the CPU 210 takes the shooting data, the human hole number, and the selected input window IW31 to IW31. Any one of the IWs 34 is linked and transmitted to the server 100. Note that the image of the shooting data is also displayed in any of the selected input windows IW31 to IW34. The CPU 110 of the server 100 stores the received photographing data in the hard disk drive 120 in association with the human hole number and any of the input windows IW31 to IW34. Note that if the captured image data is recorded in the hard disk drive 120, the CPU 110 adds the captured data and transmits it to the terminal 200 when transmitting the GUI3 data. For this reason, when the GUI 3 is displayed on the display 250, a photographed photograph image is displayed.

  When the investigator presses the list display button B13 of GUI 1 shown in FIG. 7 with the investigation result of the investigator recorded in the hard disk drive 120 by the investigation result input process described above, the terminal 200 causes the on-site investigation. A result transmission request can be transmitted to the server 100 and a response can be received and displayed on the display 250. Of course, the server 100 can output the survey result data recorded in the hard disk drive 120 to a display device or a printing device connected to the server 100.

  According to the survey result input process having such a configuration, the investigator simply performs the operation of inputting the survey result using the terminal 200 at the survey site, and displays the survey result for each survey target person hole on the server 100. Can be managed with electronic data. Therefore, it is not necessary to bring the field survey results back to the office and organize them, which greatly improves the efficiency of the survey. In addition, since the terminal 200 accepts the input of the investigation result using the GUI data received from the server 100, it is not necessary for each of the terminals 200 to store the GUI. Therefore, the configuration of the terminal can be simplified and high versatility can be obtained. Further, when it is desired to change the survey item, such as increasing the number of survey items, if the GUI data is modified on the server 100, it can be reflected in all the terminals 200, so the survey item can be changed flexibly and efficiently. Yes. Further, if each terminal 200 is configured to store the GUI data, the number of the hole that has been surveyed by a certain investigator, that is, the number of the hole in the entry in which the survey result is recorded in the survey result table 122, is stored. In the case where the survey result of the survey result table 122 is input to the server 100 from the terminal 200 to the server 100, the survey result of the survey result table 122 May be updated by mistake. On the other hand, if the terminal 200 is configured to receive GUI data from the server 100 as in the present embodiment, such erroneous updates can be suppressed. As described above, this effect can be further enhanced by combining with the configuration in which the result of the survey that has already been performed is displayed in each input window of GUI2.

A-5. Layout diagram display processing:
A layout diagram display process in the field survey support system 20 will be described. The layout diagram display process is a process for displaying on the display 250 a layout diagram showing the positions of the human holes to be examined existing in a predetermined range. The layout diagram corresponds to the position diagram of the claims. The flow of the layout diagram display process is shown in FIG. As shown in the drawing, in the layout diagram display process, first, the CPU 210 of the terminal 200 transmits a layout diagram request to the terminal 200 as a process of the position diagram acquisition unit 215 (step S510). This process is executed when the investigator presses the layout diagram display button B14 of GUI 1 shown in FIG. Note that when the layout diagram display button B14 is pressed in a state where the search condition is specified in the search screen window W11, the CPU 210 transmits a request for a layout diagram associated with the input search condition.

  On the other hand, when the CPU 110 of the server 100 receives a layout diagram request from the terminal 200 as the processing of the position map transmission unit 113, the CPU 110 superimposes the position of each human hole on the map data 123 and whether there is an abnormality in each human hole. A layout diagram to which the progress of the survey is added is generated (step S610). In this embodiment, the layout diagram is finally generated as a PDF file. In this way, if a layout diagram is generated in a highly versatile file format, it becomes easy to use in the terminal 200, and versatility increases.

  Specifically, the CPU 110 acquires the geographical coordinates of the human holes corresponding to all the human hole numbers recorded in the investigation target information table 121 when the search condition is not associated with the received layout diagram request. To do. Next, the CPU 110 cuts out from the map data 123 map data in a range in which all of the acquired geographic coordinates are contained. Next, CPU110 superimposes the marking image which shows the position of each human hole on the image which the extracted map data represents. At that time, the marking image has a different display mode according to the presence / absence of abnormality of each human hole and the progress of the investigation. The scale of the map data may be appropriately set in consideration of the usability at the terminal 200 and the data size of the map data.

  A specific example of the superimposed image generated here is shown in FIG. In the superimposed image shown in the figure, the positions of the human holes are plotted with marking images “◯”, “●”, and “□” over the entire investigation range. “◯” indicates no abnormality (inspected), and “●” indicates abnormality (inspected). The presence / absence of this abnormality reflects the data in the “abnormal” area of the investigation result table 122. “□” indicates unexamined. In this embodiment, whether or not the data has been investigated is determined based on whether or not data is stored in the “abnormal” area of the investigation result table 122.

  In the present embodiment, as described above, the presence / absence of each human hole and the progress of the survey are added to the map data by changing the shape of the marking image. However, the color may be changed. That is, what is necessary is just to display in a different display mode according to the difference between the presence or absence of each hole and the progress of the investigation. Of course, the present invention is not limited to a configuration that employs different display modes, and after all the human holes are superimposed in the same display mode, the presence / absence of abnormality of each human hole and the progress of the investigation may be added as character information.

  In the above example, the presence / absence of abnormality reflects the data in the “abnormality” area of the investigation result table 122. However, the determination of the presence / absence of abnormality may be performed based on other investigation items. For example, the CPU 110 may search for a predetermined survey item area in the survey result table 122 and determine that there is an abnormality when a predetermined keyword is included. More specifically, when the “step” region is searched and “floating” is stored, the human hole corresponding to the human hole number of the entry may be determined to be abnormal. Or you may judge abnormality based on a measured numerical value. For example, a design value of a predetermined survey item (for example, a gradient) of each human hole or a measurement value measured during maintenance is recorded in the survey target information table 121 or the survey result table 122, and this pre-recorded numerical value is recorded. May be determined as abnormal if there is a predetermined deviation between the two values.

  Further, instead of or in addition to the presence / absence of abnormality, survey results for other survey items may be added. In addition, as the progress of the survey, in the above example, information indicating whether or not the survey has been performed is added. However, instead of or in addition to this, a survey execution date or a surveyor may be added. . That is, the desired survey information based on the survey result recorded in the survey result table 122 may be added. In addition, schedule information recorded in the survey target information table 121 and investigator information may be added. Such various additional information may be configured to be selectable and set by the user. Note that it is not essential to add additional information to the layout diagram.

  On the other hand, when a search condition is associated with the received layout diagram request, the CPU 110 searches the investigation target information table 121 for a hole number that matches the search condition, and corresponds to the searched hole number. Geographic coordinates are acquired for only the human hole, and a layout diagram is generated based on the geographical coordinates.

  Here, the description returns to FIG. When the layout diagram is generated, the CPU 110 transmits the generated layout diagram to the terminal 200 as processing of the position diagram transmission unit 113 (step S620). The CPU 210 of the terminal 200 receives this and displays the layout diagram on the display 250 as processing of the position map display unit 216 (step S520). In this embodiment, the layout diagram is displayed on the display 250 in full screen. In order to return to the GUI 2 screen, the investigator performs an operation to return to the previous screen.

  According to the layout diagram display process having such a configuration, the investigator can confirm the position of each human hole using the terminal 200 while at the investigation site, and therefore, it is necessary to always carry the layout drawing of the human hole. Absent. This improves the convenience of the investigator. In addition, it is possible to discuss investigation policies at sites other than offices, such as on-site, based on the latest investigation information, for example, investigations that have been or have not been conducted, information on the presence or absence of abnormalities, etc. it can. In particular, in the current state survey at the time of disaster, in many cases, the progress of the survey on the current day, discussion of the policy of the survey on the following day, etc. are conducted at a place different from the office, such as a gymnasium or public hall. Alternatively, since it takes a relatively long time to move to an office or a field office at a construction site over a wide area, a simple meeting such as confirmation of the progress of the construction and an inspection schedule may be performed at the site. In these cases as well, the work efficiency can be greatly improved because the discussion can be conducted at the conference venue based on the latest survey information. Moreover, since the survey information is dropped on the layout diagram, it is very easy to understand. Note that the type of the terminal 200 that displays the layout diagram may be used depending on the situation. For example, investigators use mobile phones and PDAs that are small and easy to carry during field surveys, and use a laptop computer with a relatively large display when conducting discussions after the survey. May be.

  In addition, the investigator can easily check on the layout diagram the survey schedule, for example, the human hole to be investigated on the day, using the terminal 200 at the survey site. As a result, it is possible to prevent the investigator from making a mistake in the survey target. Alternatively, the investigator does not necessarily need to carry a drawing or the like on which the schedule is written.

A-6. Survey target map display processing:
A survey target map display process in the field survey support system 20 will be described. The survey target map display process is a process of displaying a survey target map indicating the position of a specific survey target on the display 250. The survey target map corresponds to the map image in the claims. The flow of the survey target map display process is shown in FIG. As illustrated, in the survey target map display process, first, the CPU 210 of the terminal 200 receives a specific human hole to be surveyed (step S710). Specifically, when the investigator presses the map display button B23 of GUI2, the CPU 210 accepts the human hole number displayed in the display window DW21 of the GUI2.

  When the human hole number is received, the CPU 210 uses the GPS receiver 280 to acquire the geographical coordinates of the own device (step S720). When the geographical coordinates are acquired, the CPU 210 transmits a request for a survey target map to the terminal 200 as processing of the map image acquisition unit 217 (step S730). The request for the survey target map is made by designating the human hole number and the acquired geographical coordinates. There may be a plurality of human hole numbers. Alternatively, a search condition for a human hole number may be used instead of the human hole number.

  On the other hand, when the CPU 210 of the terminal 200 receives the request for the survey target map, as the processing of the geographic image transmission unit 114, the survey target in which the human hole corresponding to the specified human hole information and the position of the terminal 200 are displayed. A map is acquired (step S810). In this embodiment, the CPU 210 designates the geographical coordinates corresponding to the designated human hole information and the geographical coordinates of the terminal 200 to the server providing the map image via the Internet INT, A map image showing geographical coordinates is acquired as a survey target map. Geographic coordinates corresponding to the human hole information are acquired with reference to the survey target information table 121. In this way, a desired geographic image can be easily obtained using a service published on the Internet INT. However, the map image acquisition method is not limited to the above-described example, and the CPU 110 may generate the map image based on the map data 123 as in the layout diagram. In the present embodiment, the acquired map image is finally converted into a PDF format file.

  It is not always necessary to acquire a map image illustrating both the human hole corresponding to the specified human hole information and the position of the terminal 200. When the terminal 200 specifies only one of the geographical coordinates corresponding to the specified human hole information and the geographical coordinates of the terminal 200 and requests a survey target map, the specified geography What is necessary is just to acquire the investigation object map which illustrated only the position corresponding to a coordinate.

  When the survey target map is acquired, the CPU 110 transmits the survey target map to the terminal 200 as processing of the geographic image transmission unit 114 (step S820). On the other hand, the CPU 210 of the terminal 200 receives the survey target map and displays the received survey target map on the display 250 as processing of the map image display unit 218 (step S740).

  According to the survey target map display processing, the investigator uses the terminal 200 at the survey site to check the position of a specific human hole, for example, the position of the next human hole to be investigated, and the position of the terminal 200, that is, the survey. The relationship with the position of the worker can be easily confirmed on the map. As a result, the route to reach a specific human hole can be easily grasped, and work efficiency is improved. In particular, investigators are often dispatched from areas other than the disaster-stricken areas in current state surveys during disasters. In such a case, the investigator is not guided by the geography of the survey site, and conventionally, the researcher often has a hard time to reach the desired position. Such a problem is common in fold surveys for narrowing down the facility construction schedule from a plurality of candidate sites. This is because investigators are often dispatched from survey companies in urban areas and are often unfamiliar with the local geography. However, according to the survey target map display processing of the present embodiment, such inefficiency is greatly improved.

  The above-described configuration for displaying a map of the position of the terminal 200 can also be applied to layout diagram display processing. In this way, the investigator can check the position of each human hole and the position of the investigator on the map using the terminal 200. As a result, the investigator can easily grasp the positional relationship between each person's hole and the self, so that it is possible to investigate each investigation object by setting an efficient investigation order.

B. Variations:
A modification of the above embodiment will be described.
B-1. Modification 1:
It is also possible to employ a configuration for preventing input leakage with respect to the input to GUI2 or GUI3 described above. For example, when the investigator performs an operation of closing GUI 2 or GUI 3 before all the input items are input, that is, before being recorded in the survey result table 122, the server 100 It is good also as a structure which transmits a warning message. The operation of closing the GUI 2 or the GUI 3 can be performed, for example, by detecting session disconnection or a request for a different WEB page. Alternatively, the terminal 200 may be configured such that the terminal 200 cannot transmit the investigation result to the server 100 until all input items are input.

B-2. Modification 2:
For the input to the GUI 2 described above, it is possible to adopt a configuration for checking the consistency of input contents. For example, when the contents of all survey items recorded in the survey result table 122 are recorded for a predetermined entry, the server 100 may check the consistency between the presence / absence of an abnormality and other input items. . For example, if the relationship between the abnormality “Yes” and the step “Float” and the relationship between the abnormality “None” and the step “None” are linked and recorded in a relationship other than this, it is inconsistent. You may judge that there is. In such a case, a warning message may be transmitted to the terminal 200. By doing so, the investigator can confirm the input contents again by the warning message. As a result, it is not possible to know which input item is correct, and it is possible to avoid the occurrence of an inefficient situation in which a re-survey is performed.

B-3. Modification 3:
The on-site survey support system 20 described above can be widely applied to various on-site surveys, not limited to sewerage facility surveys and current situation surveys during disasters. For example, the present invention can be applied to maintenance inspections for various facilities such as waterworks facilities, railways, and roads, and field surveys when selecting a facility construction planned site from a plurality of candidate sites. Moreover, not only the field survey for the geographically distributed facilities, but also the facilities and equipment collected in a predetermined range can be the target of the survey. For example, for various structures, buildings, plants, etc., it can be applied to management of construction records at construction sites, construction supervision of construction works, maintenance management inspection after construction, and the like. When applied to an intensive facility, the layout diagram described above may be replaced with, for example, a facility layout diagram representing the layout of each facility in the facility, a device layout diagram representing the layout of each device constituting the plant, or the like. In these cases, the layout diagram may be configured to display only facilities and devices that meet the search conditions, such as a first floor device layout diagram, a second floor device layout diagram, and a water treatment system facility layout diagram.

  As mentioned above, although embodiment of this invention was described, elements other than the element corresponding to the element described in the independent claim among the components in embodiment mentioned above are additional elements, are abbreviate | omitted suitably, or Combinations are possible. In addition, the present invention is not limited to such an embodiment, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, the present invention can be realized not only as a site survey support system but also as a server, a terminal, a program thereof, a storage medium storing the program, a site survey method, and the like constituting the site survey support system.
