A test information management system 1 according to an embodiment of the present invention will be described with reference to the drawings. The inspection information management system 1 is used for progress management of leakage inspections in gas pipes. The gas conduit includes a main pipe and an inner pipe. Main pipes are gas pipes that are laid parallel to roads. An internal pipe is a gas pipe buried in the site of a building or the like. The leakage inspection according to this embodiment includes an inspection (hereinafter referred to as "continuous inspection") that is continuously performed on the main branch pipe using the cart-type gas detector 500 of FIG. (hereinafter referred to as “discontinuous inspection”).

In the continuous inspection, as shown in FIG. 1, the inspector P pushes and walks in the direction in which the main branch pipe is laid while maintaining the cart-type gas detector 500 in an operating state. The cart-type gas detector 500 successively sucks and collects surface air, and continuously detects whether or not gas is leaking therein. In the discontinuous inspection, the inspector P moves along the inner pipe and activates the gas detector at appropriate timings. Thereby, the gas detector discontinuously detects whether gas is leaking into the surrounding air.

The main purpose of the inspection information management system 1 is to automatically acquire and manage an inspected range in leak inspection of gas pipes as described above. In the process of acquiring the inspected range by the inspection information management system 1, the main branch pipe mode (first mode according to the present invention) corresponding to the continuous inspection of the main branch pipe and the inner pipe mode corresponding to the discontinuous inspection of the inner pipe (the second mode referred to in the present invention) is selected. Details of each mode will be described later.

Satellite positioning using the GNSS terminal 400 is used in deriving the inspected range in this embodiment. As a result, progress management of examinations is automated. The GNSS terminal 400 is an RTK-GNSS (Real Time Kinematic Global Navigation Satellite System) receiver. An RTK-GNSS receiver is a device that performs GNSS observation at an observation point by RTK-GNSS positioning. RTK-GNSS positioning performs GNSS observation simultaneously with a reference station whose position is known and an observation point whose position is to be determined, transmits the data observed at the reference station to the observation point in real time, and observes based on the position measurement of the reference station. This is a positioning method that obtains the measurement result of the position of a point in real time. A measurement result is acquired for each unit time.

According to the RTK method, deviation of position information at an observation point is corrected by transmitting correction information to the observation point. Therefore, it is possible to measure with an accuracy of subcentimeter class with an error of 2 cm to 5 cm. As a specific positioning system, any system such as GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), BeiDou, Galileo, QZSS (Quasi-Zenith Satellite System) may be used.

The examination information management system 1 has a database 100 (storage means in the present invention), a server 200, a portable terminal 300 and the GNSS terminal 400, as shown in FIG. Each of the database 100, the server 200, the mobile terminal 300, and the GNSS terminal 400 includes hardware such as a CPU (Central Processing Unit), memory device (hereinafter referred to as memory), various interfaces, etc., and software such as program data stored in the memory. and is constructed by These software can be downloaded via the Internet or distributed by various recording media. The following functions are realized by the hardware functioning based on the software.

The portable terminal 300 and the GNSS terminal 400 are carried by the inspector P and used by the inspector P at the same time as the leakage inspection for the gas pipe. During inspection, the mobile terminal 300 and the GNSS terminal 400 are connected to each other through short-range wireless communication such as Bluetooth (registered trademark) and Wi-Fi (registered trademark), and perform data communication between them. The server 200 is installed at a location distant from the examination location, and is connected to the mobile terminal 300 through a communication network N such as the Internet. The database 100 and the server 200 are connected to each other through a LAN (Local Area Network) and perform data communication therebetween.

The database 100 has map data 110, piping data 120, building data 130, and inspection position data 140, as shown in FIG. The map data 110 is data indicating the layout of roads, buildings, etc. on the map in the installation range of the gas pipe, and more specifically, data representing the map image C11 of the screen IM1 as shown in FIG.

The pipe data 120 includes pipe layout data 121 (data indicating layout information referred to in the present invention) and inspected range data 122 . The pipe layout data 121 is an image showing the distribution of all the buried gas pipes on the map. Specifically, the pipe layout data 121 is data representing the layout of pipes on a map as shown in the pipe layout image C12 of FIG. The inspected range data 122 is data indicating which of the pipe arrangements indicated by the pipe arrangement data 121 is an inspected area. Specifically, the inspected range data 122 is data representing an inspected range image C41 of the screen IM4 as shown in FIG. 6B. The inspected range data 122 is stored in the database 100 after being generated by the server 200 based on the positioning results and the pipe layout data 121 acquired by the GNSS terminal 400, as will be described later.

The building data 130 is data indicating the arrangement of selectable pin icons in the inner tube mode as described later, and more specifically, data representing the icon image C51 in FIG.

The examination position data 140 is accumulated examination position information transmitted from the mobile terminal 300 via the server 200 as will be described later.

The server 200 has a server-side inspection information processing section 210 , an inspected range derivation section 220 and a map data adjustment section 230 .

The server-side examination information processing section 210 holds whether the current mode is the main branch mode or the inner tube mode. The server-side examination information processing section 210 switches between the main branch tube mode and the inner tube mode when a mode switching instruction is transmitted from the mobile terminal 300 to the server 200 .

In this branch mode, examination position information is sequentially transmitted from the portable terminal 300 as described later. The server-side examination information processing section 210 sequentially transfers the examination position information to the database 100 . The database 100 stores examination position information from the server-side examination information processing section 210 as examination position data 140 .

In the inner tube mode, position information (hereinafter referred to as candidate position information) that is a candidate for an examination position is transmitted from the mobile terminal 300 at the timing when the examination is performed as will be described later. The server-side examination information processing section 210 collates the candidate position information from the mobile terminal 300 with the examination position data 140 already accumulated in the database 100 . Then, when the collation result satisfies a predetermined condition, the server-side examination information processing section 210 forms the candidate position information as examination position information and transfers it to the database 100 . In addition, the server-side examination information processing unit 210 replies to the portable terminal 300 that the content indicated by the candidate position information is permitted as the examination position. The database 100 stores examination position information from the server-side examination information processing section 210 as examination position data 140 . If the collation result does not satisfy the predetermined condition, the server-side examination information processing section 210 returns to the portable terminal 300 that the content indicated by the candidate position information is not permitted as an examination position.

In the above, the predetermined condition is that the distance from the previous inspection position to the current inspection position is within 5 m. The distance of "5m" conforms to the institutional regulation that inspections for leaks in gas pipes should be performed by sucking air from the ground surface using a collector at intervals of 5m or less.

The inspected range derivation unit 220 generates inspected range data 122 based on the inspection position data 140 of the database 100 and the pipe arrangement data 121 of the database 100 . The inspected range deriving unit 220 (inspected range deriving means of the present invention) transmits the inspected range data 122 to the database 100 and stores it in the database 100 . The details of how to derive the inspected range will be described later.

The map data adjustment unit 230 generates data representing an inspection mapping image to be displayed on the mobile terminal 300 based on the map data 110, the piping data 120, the building data 130, and the inspection position data 140 stored in the database 100, and displays the data on the mobile terminal 300. Send to terminal 300 .

The inspection mapping image generated in this branch mode includes an image showing the layout of roads, buildings, etc. on the map, the current location of the inspector, the layout of the gas pipes, and the inspected range. The images shown on screens IM1, IM3 and IM4 in FIGS. 4 and 6 are examples of inspection mapping images in the main branch mode. In these screens, a map image C11 indicates the layout of roads, buildings, and the like. A pipe layout image C12 indicates the layout of pipes. An inspection position image C13 in FIGS. 4 and 6(a) and an inspection position image C43 in FIG. 6(b) indicate the inspector P's position. An inspected range image C41 indicates the inspected range.

There are two types of inspection mapping images generated in inner tube mode. One of the two inspection mapping images is an image showing the layout of roads, buildings, etc. on a map and pin icons superimposed on each building to be inspected (hereinafter referred to as building selection image). On the screen IM5, a map image C11 indicates the arrangement of roads, buildings, and the like. An icon image C51 indicates a pin icon. The other of the two inspection mapping images is an image that is displayed when the pin icon is selected in one of the inspection mapping images. It includes an image (hereinafter referred to as an inspection range input image) showing the layout on the map, the layout of the gas pipes, the inspection position and the inspected range. On the screen IM6 in FIG. 8, a map image C11 indicates the arrangement of roads, buildings, and the like. An inspection position image C61 indicates the inspection position. An inspected range image C62 indicates the inspected range.

The mobile terminal 300 has a touch panel display 310 (input means in the present invention), a mode switching section 320 , a mobile-side examination information processing section 330 (inspection position acquisition means in the present invention), and a map display section 340 . A smartphone, a tablet terminal, or the like is used as the mobile terminal 300 .

The touch panel display 310 has a screen that displays characters, images, etc., and can detect the position where the user's finger or the like touches. The inspector P performs user input to the mobile terminal 300 through a GUI (Graphical User Interface) implemented using the touch panel display 310 . A user input through the GUI can give an instruction to switch between the main branch tube mode and the inner tube mode. In addition, as will be described later, in the inner tube mode, user input for selecting an icon image displayed on the screen and user input for indicating the timing of inspection execution are possible.

When the user inputs an instruction to switch between the main branch mode and the inner tube mode through the GUI, the mode switching unit 320 transmits an instruction to switch the mode to the server 200 .

The mobile-side test information processing unit 330 acquires positioning results transmitted from the GNSS terminal 400 every second, for example, at any time. This positioning result indicates the latitude and longitude of the GNSS terminal 400 . In this branch mode, each time the mobile-side inspection information processing unit 330 receives a positioning result from the GNSS terminal 400, the mobile-side inspection information processing unit 330 stores the information indicating the positioning result as the position where the inspection was performed (inspection position in the present invention). It is transmitted to the server 200 as examination position information to be shown. On the other hand, in the internal tube mode, the mobile-side examination information processing unit 330 transmits the position information indicated by the positioning result from the GNSS terminal 400 to the server 200 at the timing based on the user input through the GUI. Further, the touch panel display 310 is made to display according to the reply from the server 200 to this.

The map display unit 340 receives data representing an inspection mapping image from the server 200 and causes the touch panel display 310 to display the inspection mapping image based on the data. As described above, the images shown in screens IM1 and IM3-IM6 in FIGS. 4 and 6-8 are examples of inspection mapping images.

Details of a method for deriving an inspected range by the inspection information management system 1 will be described below with reference to FIGS. 5 to 8. FIG. In this branch mode, the inspected range derivation unit 220 derives the inspected range based on buffering. As shown in FIG. 5, buffering is a process of deriving a buffer area 20 corresponding to a specific range with respect to the movement trajectory 10 of the inspector P. FIG. The buffer area 20 corresponds to an area obtained by superimposing areas within circles having a radius of 2.5 m centered on each point on the movement trajectory 10 of the inspector P. FIG. The radius of "2.5 m" conforms to the regulation that the inspection should be performed by sucking air on the ground surface using a collector at intervals of 5 m or less, as described above. This is because performing inspections at intervals of 5 m corresponds to setting the range within a radius of 2.5 m around the position where the inspection was performed as the inspected range. The inspected range derivation unit 220 acquires the buffer area 20 based on the inspection position data 140 . Next, the inspected range deriving unit 220 compares the arrangement of pipes indicated by the pipe arrangement data 121 with the buffer area 20, and derives the range of the piping included in the buffer area 20 as the inspected range.

When the inspector P moves from the position shown in the inspection position image C13 of FIG. 6(a) to the position shown in the inspection position image C43 of FIG. 6(b), the inspected range is obtained as follows. be. As the inspector P moves, information indicating positioning results from the GNSS terminal 400 carried by the inspector P is sequentially transmitted to the server 200 as inspection position information through the mobile terminal 300 . The server-side examination information processing section 210 accumulates examination position information from the mobile terminal 300 as examination position data 140 in the database 100 . On the other hand, the inspected range derivation unit 220 refers to the inspection position data 140 stored in the database 100, and acquires a buffer area based on the movement trajectory from the inspection start position of the inspector P to the current position. A region B indicated by a dashed dotted line in FIG. 6(b) indicates a buffer region obtained when the movement trajectory from the position indicated by C13 to the position indicated by C43 is used as a reference. Next, the inspected range derivation unit 220 derives an inspected range by comparing the acquired buffer area and the pipe arrangement data 121 . Specifically, the inspected range corresponds to the range (the range of the image C41) located within the region B in FIG. 6(b) in the gas pipe. In the gas conduit, the range of the images C44a and C44b is the range of the gas conduit excluding the image C41, and corresponds to the uninspected range.

In the internal tube mode, the inspected range deriving unit 220 of the server 200 derives the inspected range based on the user's input from the portable terminal 300 indicating the timing of inspection execution by the inspector P as follows. First, based on the inspection mapping image data from the server 200, the map display unit 340 of the mobile terminal 300 causes the touch panel display 310 to display a building selection image, an example of which is shown in the screen IM5 of FIG. When inspector P selects one of the pin icons (icon image C51 in FIG. 7) included in the building selection image through the GUI, map display unit 340 displays an example on screen IM6 in FIG. is displayed on the touch panel display 310 .

On the screen of the touch panel display 310 on which the inspection range input image is displayed, the inspector P touches any position within the display range of the inspection range input image with a finger or the like at the timing when the inspector P executes the inspection. In response to this, the mobile-side inspection information processing unit 330 of the mobile terminal 300 transmits to the server 200 information indicated by the positioning result transmitted from the GNSS terminal 400 at that timing as candidate position information of the inspection position. In the server 200, the server-side examination information processing section 210 determines whether or not the candidate position information is permitted as an examination position. As a result, when the server 200 transmits that the inspection position is not allowed, the mobile-side inspection information processing section 330 displays on the screen of the touch panel display 310 that "the inspection position does not meet the conditions." When the server 200 transmits that the examination position is permitted, the mobile-side examination information processing section 330 displays an icon designating the examination position on the screen of the touch panel display 310 . An icon image C61 of “●” in FIG. 8 is one example.

When the server-side inspection information processing unit 210 determines that the candidate position information is accepted as the inspection position, the inspected range deriving unit 220 of the server 200 calculates the inspected range based on the pipe arrangement data 121 and the inspection position data 140. derive Specifically, as shown in FIG. 9, in the arrangement of the gas pipes indicated by the pipe arrangement data 121, the range from the previous inspection position to the current inspection position is defined as the inspected range. Since the candidate position information is accepted as the inspection position, the distance from the previous inspection position to the current inspection position is 5 m or less. By repeating such an inspection many times while the inspector P moves along the gas pipe, the inspected range shown in FIG. 10 is acquired, and each inspected position and its number are acquired.

According to the present embodiment described above, the inspected range deriving unit 220 of the server 200 determines the location of the gas pipes indicated by the piping location data 121 stored in the database 100 based on the inspection position information from the mobile terminal 300. Derive the inspected range. Therefore, it is possible to automate inspection progress management.

In addition, in this embodiment, as a mode with a different method of acquiring inspection position information, one of the main branch pipe mode and the inner pipe mode can be selected. In the main branch mode, inspection position information is acquired based on the positioning result acquired by the GNSS terminal 400 for each unit time. Therefore, inspection positions are continuously acquired according to the continuous inspection in the main branch mode. In the inner tube mode, inspection position information is acquired based on the positioning result of the GNSS terminal 400 acquired at the timing when a finger or the like is brought into contact with the screen of the touch panel display 310 on which the inspection range input image is displayed. Therefore, the inspection position at the timing of inspection execution is appropriately acquired according to the discontinuous inspection in the inner tube mode.

Further, in the present embodiment, the inspected range derivation unit 220 determines that gas pipes within a range of a predetermined distance (2.5 m) from the position indicated by the inspection position information have been inspected. Therefore, the inspected range can be properly obtained.

Further, in the present embodiment, an inspection mapping image indicating the inspected range is displayed on the screen of the touch panel display 310 of the portable terminal 300 carried by the inspector P. FIG. Therefore, the inspector P can proceed with the inspection while confirming the inspected range.

Further, in the present embodiment, in the inner tube mode in which examinations are performed discontinuously, user input is made through the GUI of the mobile terminal 300 according to the timing at which the examinations are performed. Based on the timing, the positioning result from the GNSS terminal 400 is transmitted to the server 200 as candidate position information of the inspection position. As a result, the inspection position can be acquired appropriately in accordance with the timing of inspection execution according to the user input.
