[0001] The present invention manages the state of the pipeline. Pipeline management system Regarding. [Background technology]

[0002] Patent Document 1 describes attaching IC tags to transportation pipes that make up a pipeline. The IC tags store information about the pipe's raw materials, manufacturing date, manufacturing plant, and other information about the joints, in association with identification data unique to the pipe. The information on the IC tags is then read by a reader / writer, and this information is collectively managed by a management server for each transportation pipe. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6816222 Summary of the Invention [Problem to be solved by the invention]

[0004] Once a transport pipe is laid underground, it is difficult to grasp changes in its condition due to factors such as earthquake motion and ground movement, or deterioration over time. For example, a pipeline is made up of pipes connected with joints, but it is difficult to grasp detailed changes in the condition of the pipeline, such as which section (which pipe) in a long pipeline is particularly severely deteriorated. This issue applies not only to buried pipes, but also to exposed pipes. [Means for solving the problem]

[0005] A pipeline management system for solving the above problem is a pipeline management system for managing a pipeline formed by connecting a plurality of transport pipes, comprising: The pipeline includes a main pipeline, a bypass pipeline for the main pipeline, and an auxiliary facility including a valve to which a valve ID is assigned for switching between the main pipeline and the bypass pipeline, The transport pipe buta sensor for measuring the state of the transport pipe and a communication unit for transmitting measurement data measured by the sensor; and an IC tag with a tag ID assigned Equipped with 、 the pipeline; Associated with the tag ID Manage the measurement data in the transport pipe a status management database and an ancillary facility database that manages the status of the valve in association with the valve ID. The system includes a management server and a relay device that receives the measurement data transmitted from the communication unit and transmits the measurement data to the management server. The management server determines that the measurement data is normal when it satisfies the conditions of a normal model, and determines that the measurement data is abnormal when it does not meet the conditions, and controls the opening and closing of the valve.

[0006] According to the above configuration, the condition of the transport pipes that make up the installed pipeline is measured by a sensor attached to an IC tag on the transport pipe, and the measured measurement data is continuously or periodically transmitted to a management server. This allows for centralized management of the condition of the transport pipes that make up the pipeline. When an abnormality in the transport pipe is detected, the management server can, for example, switch the pipeline to be used. Furthermore, the remaining useful life of the transport pipe can be predicted from the measurement data transmitted from the IC tag. In addition, when the conditions of the normal model are not met, the management server determines that there is an abnormality and reduces the flow rate in the section that includes the transport pipe that has been determined to be abnormal, or can block the flow in the section that includes the transport pipe that has been determined to be abnormal.

[0007] In the pipeline management system, the transport pipe may further include a power generation unit that supplies power to the sensor and the communication unit. With this configuration, the power generation unit can generate power for the IC tag to transmit measurement data.

[0008] In the pipeline management system, the sensor may be a strain sensor that detects strain in the transport pipe. By measuring the strain in the transport pipe, the degree of deterioration due to earthquake movement, ground movement, aging, etc. can be managed.

[0009] In the pipeline management system, the sensor may include a flow rate sensor that detects the flow rate of the transport pipe. According to the above configuration, by measuring the flow rate of the transport pipe, the degree of deterioration of the inner circumferential surface of the transport pipe can be managed.

[0010] In the pipeline management system, the sensor Inner surfaceThe transport pipe may be configured to include a surface roughness sensor for detecting the surface roughness. According to the above configuration, by measuring the surface roughness of the transport pipe, it is possible to manage the degree of deterioration due to aging or the like.

[0011] In the pipeline management system, the transport pipe may be made of a plastic pipe. This configuration allows the pipeline to be adapted to uneven settlement in soft ground and ground distortion caused by earthquakes, and also provides excellent abrasion resistance and impact resistance. Furthermore, deterioration of the plastic pipe can be managed.

[0012] In the pipeline management system, the transport pipe may be a buried pipe. According to the above configuration, even if the transport pipe is a buried pipe, deterioration of the transport pipe can be managed in accordance with the underground environment.

[0013] The transport pipe for solving the above problem is a transport pipe constituting a pipeline, and includes a sensor that measures the condition of the transport pipe, and a communication unit that transmits measurement data measured by the sensor to an external device. With the above configuration, the condition of the transport pipe can be transmitted to a management server. This allows the management server to manage the condition of the transport pipe and predict the remaining useful life, etc. [Effects of the Invention]

[0014] According to the present invention, the state of the pipeline can be managed in detail. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. 1 is a diagram showing the overall configuration of a pipeline management system. [Figure 2] FIG. 10 is a diagram showing the configuration of an IC tag provided on a transport pipe. [Figure 3] FIG. 2 is a diagram illustrating a configuration of a management server. DETAILED DESCRIPTION OF THE INVENTION

[0016] A pipeline management system to which the present invention is applied will be described below with reference to the drawings. [Pipeline configuration] As shown in Figure 1, a pipeline system to be managed by a pipeline management system to which the present invention is applied is a pipeline system that transmits and distributes liquids such as water through pressure pipelines constructed by burying prefabricated pipes, and is composed, for example, of a pipeline 1 and its ancillary facilities 2. The ancillary facilities 2 include adjustment facilities, pressure regulation facilities, pumping facilities, water distribution facilities, water metering facilities, ventilation facilities, protection facilities, management facilities, and other water utilization facilities.

[0017] The pipeline 1 may be, for example, a water drainage pipeline or an agricultural water pipeline. The transport pipe 3 constituting the pipeline 1 is a resin pipe such as a thermoplastic resin pipe or a thermosetting resin pipe. For example, the transport pipe 3 is molded from a thermoplastic resin such as high-density polyethylene, polypropylene, ultra-high molecular weight polyethylene, rigid polyvinyl chloride, or glass fiber reinforced polyethylene. The transport pipe 3 may further contain additives such as pigments, antioxidants, and stabilizers, or may contain a coupling material. The transport pipe 3 has a large diameter, for example, an inner diameter of approximately 100 mm to 3000 mm. Alternatively, the inner diameter may be, for example, 1000 mm or more. The transport pipe 3 is connected using an electric fusion joint or a butt fusion joint. For example, the transport pipe 3 is a buried pipe buried underground 9 to which internal and external pressures are simultaneously applied.

[0018] The buried pipe is buried to a depth of, for example, 1 m to several meters from the surface. In this way, if the transport pipe 3 is a resin pipe, the pipeline 1 can cope with uneven settlement in soft ground and ground distortion caused by earthquakes, and also has excellent abrasion resistance and impact resistance.

[0019] The pipeline 1 includes a main pipeline 4 and a bypass pipeline 5 for the main pipeline 4. The pipeline 1 also includes a management center 6 including a management server 31. When the main pipeline 4 is damaged, for example, due to earthquake motion or ground movement, or due to aging, the management center 6 controls the control devices 8 such as valves in the ancillary facilities 2 to shut off the section of the main pipeline 4 that includes the damaged part, thereby switching to the bypass pipeline 5. The main pipeline 4 is also connected to the bypass pipeline 5 in order to reduce the flow rate of the main pipeline 4 when, for example, the allowable flow rate of the main pipeline 4 is exceeded.

[0020] As shown in FIG. 2, an IC tag 11 is integrally attached to a transport pipe 3 constituting a pipeline 1. For example, if the transport pipe 3 is a straight pipe or a curved pipe, it has two ends, each of which serves as a joint for connecting to another transport pipe 3. If the transport pipe 3 is a branched pipe, it has three or more ends, each of which serves as a joint for connecting to another transport pipe 3. In such a transport pipe 3, the IC tag 11 is, for example, provided at or near an end that constitutes a joint that is more likely to become a leak location than other parts. Of course, the IC tag 11 may also be attached to other locations.

[0021] [Overall configuration of pipeline management system] The pipeline management system includes an IC tag 11 installed in the transport pipe 3, a relay device 21 for communicating with the IC tag 11, and a management server 31 for managing information transmitted from the IC tag 11.

[0022] [Configuration of IC tag] As shown in FIG. 2, the IC tag 11 includes one or more sensors 12, a power generation unit 13, a power storage unit 14, a communication unit 15, and a control unit 16.

[0023] The sensors 12 include a strain sensor 12a, a flow rate sensor 12b, and a surface roughness sensor 12c. The strain sensor 12a measures the strain of the transport pipe 3. The strain can be used to determine whether the transport pipe 3 has been damaged or cracked due to seismic activity, ground deformation, or seismic changes. The strain sensor 12a is, for example, a plastic strain gauge. A plastic strain gauge has a structure in which a metal foil laid out in a zigzag pattern is attached to an insulator. The change in electrical resistance accompanying the deformation of the metal foil is measured and converted into the strain of the transport pipe 3. The strain sensor 12a is, for example, a strain gauge that utilizes the piezoresistance effect, in which the electrical resistivity of a semiconductor changes with stress. The strain sensor 12a detects strain in the circumferential direction and the axial direction of the transport pipe 3. The strain sensor 12a is not limited to these examples. Alternatively, multiple strain sensors 12a of this type may be used in combination.

[0024] The flow rate sensor 12b can determine whether the current flow rate in the transport pipe 3 has reached the maximum flow rate or is within the range of the designed flow rate. One example of the flow rate sensor 12b is an optical flow meter that employs a laser Doppler method. This optical flow meter irradiates a laser beam onto the liquid flowing through the transport pipe 3 and measures the flow rate of the liquid from the frequency change of the reflected wave (Doppler effect) that occurs when the laser beam hits particles moving within the liquid. Note that the flow rate sensor 12b is not limited to these examples. It may also be used in combination with a flow rate sensor 12b based on another principle.

[0025] The surface roughness sensor 12c can grasp the degree of surface deterioration due to aging on the surface of the transport pipe 3. This is because the surface of a resin pipe becomes rougher over time. As an example, the surface roughness sensor 12c is a contact-type measuring instrument in which the tip of a stylus directly touches the surface of the transport pipe 3, traces the surface with the stylus, and electrically detects the up and down movement of the stylus. Alternatively, it is a non-contact-type measuring instrument that obtains the surface roughness by acquiring the surface shape from the information obtained by irradiating the surface of the transport pipe 3 with laser light. However, the surface roughness sensor 12c is not limited to these examples. Furthermore, it may be used in combination with a surface roughness sensor 12c based on a different principle.

[0026] The power generation unit 13 generates power by itself in the IC tag 11 and supplies it to the various sensors 12 and the communication unit 15. A liquid, such as water, flows through the transport pipe 3. The power generation unit 13, for example, uses the flow to turn a water wheel to generate small-scale hydroelectric power. The power generation unit 13 also generates power using magnetostrictive vibration, which is the reverse effect of magnetostriction. Specifically, in a magnetostrictive vibration power generation device, the magnetization of a magnetostrictive material changes when strain is applied to the magnetostrictive material due to expansion and contraction or vibration of the transport pipe 3 in the circumferential and axial directions. This change generates an electromotive force in a coil wound around the magnetostrictive element according to the law of electromagnetic induction. Furthermore, the power generation unit 13 may, for example, use a thermoelectric power generation element that utilizes the Seebeck effect due to the temperature difference between the transport pipe 3 and the underground temperature. The power generation unit 13 is not limited to these examples. These examples may also be used in combination.

[0027] The power generated by the power generation unit 13 is stored in the power storage unit 14. The power storage unit 14 is a multilayer ceramic capacitor, an electrolytic capacitor, an electric double layer capacitor, a lithium ion capacitor, or the like. The power stored in the power storage unit 14 is used as power to drive the various sensors 12 and the communication unit 15. Note that the power storage unit 14 may use a combination of these elements.

[0028] As an example, the communication unit 15 performs wireless communication to transmit measurement data detected by the sensor 12 to the management server 31 via the relay device 21. As an example, the communication unit 15 includes a wireless communication circuit, an antenna element, and the like that are compliant with a mobile communication system. The mobile communication system may be a fourth-generation mobile communication system, a fifth-generation mobile communication system, or the like. The communication unit 15 communicates with the base station of the cell in which the transportation pipe 3 is located, either continuously or at predetermined intervals. The communication unit 15 performs predetermined modulation processing on the transmission data for communication and transmits the data to the management server 31. The transmission data includes tag identification data (tag ID) unique to the IC tag 11, measurement data detected by the sensor 12, measurement date and time data, and the address of the management server 31 to which the measurement data is to be transmitted. The tag ID can also be used as a pipe ID, which is identification data for the transportation pipe 3 to which the IC tag 11 is attached. Note that a connection terminal may be provided for initial setup, etc.

[0029] The control unit 16 includes a calculation element, a memory element, a timer, a calendar, etc. The control unit 16 controls the sensor 12 and the communication unit 15. The memory element 16a is, for example, an integrated circuit element in which a memory circuit is configured on a semiconductor substrate. The memory element 16a stores a program for controlling the overall operation, a tag ID, an address indicating the location of the management server 31, contact information such as an email address for the terminal of the manager of the pipeline 1, etc. The memory element 16a may also store longitude and latitude data indicating the installation position of the transportation pipe 3.

[0030] Furthermore, the memory element 16a may store information at the time of manufacturing the transport pipe 3 (raw materials of the thermoplastic resin pipe 1, manufacturing date, manufacturing plant, process inspection, product inspection, packaging date, shipping destination, customer application, pipe type (electric fusion joint pipe / butt fusion joint pipe), fusion method (electric fusion / butt fusion)), etc. In the case of a transport pipe for an electric fusion joint, the memory element 16a may store the pipe type, socket inner diameter and spigot outer diameter (standard values ​​and actual measured values), heating wire resistance, etc. In the case of a butt fusion joint transport pipe, the memory element 16a may store the pipe type, diameter of the connection end, thickness of the joint (standard values ​​and actual measured values), etc. This information is stored in the IC tag 11 via the communication unit 15 during the manufacturing of the transport pipe 3.

[0031] The memory element 16a also stores construction information such as the construction date, construction site location, fusion conditions, and construction environment (weather, temperature, humidity, etc.) The construction information is managed in the lifespan management database 34 of the management server 31, and is saved via the communication unit 15 before or after installation.

[0032] The control unit 16 is in constant communication with the base station. The control unit 16 measures a predetermined period using a timer. Specifically, the processing unit 37 acquires measurement data from the sensor 12 at a first predetermined period. Then, the control unit 16 transmits the measurement data from the communication unit 15 to the management server 31 at a second predetermined period in association with a tag ID. The transmitted measurement data includes the measurement value, the measurement date and time, a sensor ID indicating the type of sensor, and the like. The first and second predetermined periods may be every few seconds, every few minutes, every few hours, every day, every few days, etc. The predetermined period may also be changed in response to an external command. For example, when an abnormal event such as heavy rain or an earthquake occurs in the area or a neighboring area, the control unit 16 shortens the interval of the predetermined period upon receiving the external command.

[0033] The IC tag 11 described above has at least the sensor 12, the power storage unit 14, the communication unit 15, and the control unit 16 mounted on a substrate, and is packaged as a single chip if possible. In the case of hydroelectric power generation, it is difficult to package the power generation unit 13 as a single unit because the water turbine must be placed inside the transport pipe 3. In this case, the water turbine and the power storage unit 14 are wired to be electrically connected. Furthermore, in the case of generating power from strain, it is possible to incorporate them into a single chip. The packaged IC tag 11 can be easily attached to the outer surface of the transport pipe 3. For example, the package of the IC tag 11 is fixed to the outer surface of the transport pipe 3 with adhesive, double-sided tape, or the like. It is preferable that the IC tag 11 installed in one transport pipe 3 be a single package, but this does not preclude a configuration in which the IC tag 11 is configured with multiple packages and electrically connected.

[0034] The IC tag 11 is a component that has a one-to-one relationship with the transport pipe 3. The IC tag 11 is attached to the transport pipe 3 when the transport pipe 3 is manufactured. Alternatively, the IC tag 11 is attached to the transport pipe 3 during construction. The location where the transport pipe 3 to which the IC tag 11 is attached is laid can be identified by associating the tag ID with map data managed by the management server 31. Specifically, the tag ID is associated with laying position data such as longitude and latitude data and laying section data of the pipeline 1, making it possible to identify the laying position of the transport pipe 3.

[0035] As another example, in adjacent transport pipes 3, the sensor 12 of the IC tag 11 installed in one transport pipe 3 may be a different sensor 12 from the sensor 12 of the other transport pipe 3. This is because adjacent transport pipes 3 often have similar installation environments and similar deterioration conditions. Also, in multiple transport pipes 3 installed in one specific area, the type of sensor 12 of the IC tag 11 installed in each transport pipe 3 may be different. This is because, in one specific area, the installation environments are similar and similar deterioration conditions. In this way, reducing the number and types of sensors 12 implemented in one IC tag 11 allows for smaller and more cost-effective packaging.

[0036] Furthermore, the IC tags 11 may be provided at all ends of all the transport pipes 3 constituting the pipeline 1, or at only one end. Furthermore, the IC tags 11 may be provided at every other pipe, every third pipe, or every other pipe in the pipeline 1.

[0037] [Configuration of relay device] The relay device 21 is an external device for the IC tag 11, and is, for example, a base station conforming to a mobile communication system. The relay device 21 includes an antenna, a communication circuit for wirelessly communicating with mobile terminals such as mobile phones and smartphones, and a communication circuit for communicating with an exchange. The relay device 21 communicates with the IC tag 11 in the transportation pipe 3 within a cell, which is an area obtained by dividing the service area and is within the range of the radio waves of the relay device 21. Data transmitted from the IC tag 11 is transmitted to the management server 31, which is the destination, via the relay device 21 and the exchange.

[0038] [Management Server Configuration] As shown in Figure 3, the management server 31 includes a status management database 32, an ancillary facility database 33, and a lifespan management database 34. The status management database 32 manages the transport pipes 3 used in the pipeline 1. The ancillary facility database 33 manages equipment such as valves (water hydrants, water control valves, etc.) of the ancillary facilities 2. The lifespan management database 34 manages the lifespan of the transport pipes 3. Furthermore, the management server 31 includes a communication unit 35 that receives data transmitted from the IC tag 11, a memory 36, and a processing unit 37 that controls the overall operation.

[0039] The status management database 32 stores and manages the measurement date and time, the amount of strain measured by the strain sensor 12a, the flow rate measured by the flow rate sensor 12b, the surface roughness measured by the surface roughness sensor 12c, and the like, in association with the tag ID assigned to the IC tag 11. This makes it possible to identify each individual transport pipe 3 that has been laid from the tag ID, and to manage the status of the transport pipe 3.

[0040] Valves and the like are installed in ancillary facilities 2 and the like located at the point where the main pipeline 4 branches off into the bypass pipeline 5. The valves and the like adjust the valve opening to regulate the flow rate of the main pipeline 4 and the bypass pipeline 5, thereby ensuring the safety of the pipeline 1 from transient phenomena. The opening and closing of the valves and the like is controlled by a control device 8 for each specified area. The ancillary facilities database 33 stores the opening degree, which is the state of the valve, in association with a valve ID, which is unique identification data assigned to the valve.

[0041] The lifespan management database 34 manages the manufacturing date, construction date, remaining useful life, laying position, etc. of the transport pipe 3 in association with the tag ID. The manufacturing date, construction date, etc. of the transport pipe 3 can be obtained from the IC tag 11 or can be input from another terminal. The remaining useful life, as will be described in detail later, is calculated from the measurement date, strain amount, flow rate, surface roughness, etc. associated with the tag ID, which are stored in the condition management database 32. The laying position can be identified on map data by being associated with the tag ID.

[0042] The communication unit 35 is connected to an external network. The communication unit 35 receives data transmitted from each IC tag 11 via the relay device 21. The data transmitted from the IC tag 11 is received as measurement data of the sensor 12 associated with the tag ID of the transmitting IC tag 11. The received measurement data is then stored in the state management database 32. The communication unit 35 also transmits control signals to the control device 8 for controlling the opening and closing of valves and the like in the ancillary facilities 2.

[0043] The memory 36 stores a normal model of the pipeline 1. The normal model stores the allowable strain amount (maximum strain amount) for each transport pipe 3 constituting the pipeline 1, the allowable flow rate and flow velocity (maximum flow rate and maximum flow velocity), the allowable surface roughness (maximum surface roughness), and the like.

[0044] The processing unit 37 acquires from the normal model the tolerance for the amount of distortion, the tolerance for the flow rate or flow velocity, the tolerance for surface roughness, etc. of the tag ID associated with the measurement data received by the communication unit 35. The processing unit 37 then compares the received measurement data with the tolerance for the amount of distortion, the tolerance for the flow rate or flow velocity, the tolerance for surface roughness, etc. If the measurement data meets the conditions of the normal model, it is determined to be normal, and if it does not, it is determined to be abnormal.

[0045] The processing unit 37 reduces the flow rate in the section including the transport pipe 3 determined to be abnormal. The processing unit 37 also blocks the flow in the section including the transport pipe 3 determined to be abnormal. To achieve this control, the processing unit 37 identifies, for example, a valve in an ancillary facility 2 located upstream of the section and transmits a control signal for the valve, etc., associated with the valve ID of the valve, etc., to the control device 8 of the ancillary facility 2. The control signal increases or decreases the opening of the valve, etc. In the example of FIG. 1 , when the main pipeline 4 includes the transport pipe 3 determined to be abnormal, the processing unit 37 closes the valve, etc., in the upstream ancillary facility 2, allowing the liquid to flow only through the bypass pipeline 5. Alternatively, the processing unit 37 allows the liquid to flow through both the main pipeline 4 and the bypass pipeline 5, reducing the flow rate in the main pipeline 4. The processing unit 37 then updates the opening rate, etc., of the valve ID of the valve, etc., that is the control target, in the ancillary facility database 33.

[0046] The processing unit 37 also predicts the remaining service life of the transport pipe 3 managed in the status management database 32. Specifically, the status management database 32 stores, in association with the tag ID, the measurement date and time, the amount of strain measured by the strain sensor 12a, the flow rate measured by the flow rate sensor 12b, the surface roughness measured by the surface roughness sensor 12c, and the like. Surface deterioration of the outer surface of the transport pipe 3 can be predicted from the amount of strain, surface roughness, and the like. Furthermore, wear on the inner surface of the transport pipe 3 can be predicted from the degree of wear, which can be calculated from the flow rate and flow velocity. The processing unit 37 applies the amount of strain, flow rate, surface roughness, and the like to a prediction function for predicting the service life of the transport pipe 3 for each tag ID, thereby predicting the service life of the transport pipe 3 to which the IC tag 11 is attached. When the remaining service life reaches a predetermined number of years, the processing unit 37 sends an email or the like to the terminal of the pipeline 1 manager, informing him or her that the time for replacement of the transport pipe 3 will soon come or has already come.

[0047] [Effects of the embodiment] The above-described embodiment can provide the following effects. (1) The condition of the transport pipes 3 constituting the laid pipeline 1 is measured by the IC tags 11 attached to the transport pipes 3, and the measured measurement data is transmitted to the management server 31. This allows the management server 31 to centrally manage the conditions of the transport pipes 3 constituting the pipeline 1. In other words, the condition of each transport pipe 3 constituting the pipeline 1 can be managed in detail. When an abnormality in the transport pipe 3 is detected, the management server 31 can, for example, switch the pipeline. Furthermore, the remaining useful life of the transport pipe 3 can be predicted from the measurement data transmitted from the IC tags 11 continuously or periodically.

[0048] (2) The power used by the IC tag 11 to transmit the measurement data from the sensor 12 can be generated by the power generation unit 13 itself. This eliminates the need to externally supply power for the sensor 12 to measure and transmit the various conditions of the transport pipe 3. In particular, in the case of a buried pipe, where it is difficult to supply power from above ground, it is effective to provide the power generation unit 13 that generates power by itself.

[0049] (3) By using a base station of a mobile communication system as the relay device 21, existing facilities can be reused. (4) By measuring the amount of strain in the transport pipe 3 using the strain sensor 12a, it is possible to manage the degree of deterioration due to earthquake movement, ground movement, aging, etc.

[0050] (5) By measuring the flow rate of the transport pipe 3 using the flow rate sensor 12b, the degree of deterioration of the inner circumferential surface of the transport pipe 3 can be managed. (6) By measuring the surface roughness of the transport pipe 3, the degree of deterioration due to aging and the like can be controlled.

[0051] (7) By using a resin pipe for the transport pipe 3, the pipeline 1 can be made to be able to cope with uneven settlement in soft ground and ground distortion caused by earthquakes, and can also be made to be excellent in abrasion resistance and impact resistance. Furthermore, deterioration according to the resin pipe can be managed.

[0052] (8) Even if the transport pipe 3 is a buried pipe, the deterioration of the transport pipe 3 can be managed according to the underground environment. (9) The status of the transport pipe 3 can be transmitted to the management server 31. This allows the management server 31 to manage the status of the transport pipe 3 and predict the remaining useful life, etc.

[0053] [Modification] The above-described pipeline 1 can also be implemented by further modifying it as follows.

[0054] The sensor 12 may be other sensors such as a water level (pressure) sensor. The sensors 12 provided in the IC tag 11 may be at least one or two of a strain sensor 12a, a flow rate sensor 12b, and a surface roughness sensor 12c. Reducing the number of sensors 12 provided in the IC tag 11 allows the IC tag 11 to be made smaller and consume less power.

[0055] The IC tag 11 and the relay device 21 may communicate with each other via a wired connection. The relay device 21 may be a reader / writer for wireless communication with the IC tag 11. The reader / writer may wirelessly communicate with the IC tag 11 and transmit the received measurement data to a base station that complies with a mobile communication system.

[0056] The relay device 21 is not limited to a base station of a mobile communication system. The transport pipe 3 may be a concrete pipe, a ductile cast iron pipe, a steel pipe, an FRPM pipe (reinforced plastic composite pipe), or the like, in addition to a resin pipe.

[0057] The transport pipe 3 may be an exposed pipe. In addition to the above-mentioned examples, the pipeline 1 may be a hydraulic pipeline for a hydroelectric power plant, a water treatment facility, a sewerage facility, a circulating water pipeline within a factory, or the like.

[0058] The pipeline 1 may be a utility tunnel that aggregates lifelines such as electric wires, optical fibers, water and sewerage pipes, and gas pipes for electricity, telephone, and communications underground, such as a road. In this case, the transport pipe 3 may be made of a resin pipe, a concrete pipe, a ductile cast iron pipe, a steel pipe, or a FRPM pipe. In the case of a utility tunnel, the IC tag 11 is provided in the transport pipe 3 that constitutes the utility tunnel. Power may be supplied to the IC tag 11 via an electric wire in the utility tunnel. Measurement data may also be transmitted from the communication unit 15 to the management server 31 via a relay device 21 installed in the utility tunnel, either wired or wirelessly. For example, the relay device 21 may be a wireless LAN device conforming to the IEEE802.1.1 standard, such as Wi-Fi.

[0059] Transport Pipe 3 may be applied to transport pipes located deep underground. Deep underground is defined as a depth that is not normally used for constructing basements (40m or more below ground level) or a depth that is not normally used for installing building foundations (10m or more below the surface of the supporting ground).
