A piping installation management system and a piping installation management method according to the present embodiment will be described with reference to FIG. A pipe installation management system and a pipe installation management method are systems and methods for managing pipe installation work for installing a plurality of pipes.

First, a pipe installation management system 10 according to this embodiment will be described with reference to FIG. A pipe installation management system 10 shown in FIG. 1 is a system for managing pipe installation work having processes as shown in FIG.

As shown in FIG. 1 , the pipe installation management system 10 includes a wireless IC tag 20 , a reading section 30 , a determination section 40 , a display section 50 and a recording section 60 .

The wireless IC tag 20 is fixed to each pipe 1 as shown in FIG. 3 and the like. The manner in which the wireless IC tag 20 is fixed to the pipe 1 is arbitrary. For example, the wireless IC tag 20 may be fixed to the outer surface of the pipe 1 or may be fixed to the inner surface of the pipe 1 . Alternatively, the wireless IC tag 20 may be housed in a recess formed in the pipe 1 or embedded in the pipe 1 . The number of wireless IC tags 20 fixed to each pipe 1 may be one.

The wireless IC tag 20 has pipe identification information associated with the corresponding pipe 1 . More specifically, although not shown, the wireless IC tag 20 includes an IC chip for recording pipe identification information and an antenna. The pipe identification information is information for identifying pipes, and is individually assigned to each pipe 1 in advance. The pipe identification information may include, for example, a pipe identification number. The pipe identification information is also called spool information. The spool information means information (for example, identification number) for identifying individual pipes 1 before being connected to other pipes 1 .

The wireless IC tag 20 is configured to acquire pipe position information indicating the position of the pipe 1 . For example, as shown in FIG. 1, each pipe 1 may be fixed with a position detection terminal 21 (position sensor). The position detection terminal 21 receives radio waves 2 emitted from satellites that make up the GPS (Global Positioning System), thereby detecting the position of the pipe 1 (more specifically, the position of the position detection terminal 21). It has become. Pipe position information detected by the position detection terminal 21 is recorded in the IC chip of the wireless IC tag 20 . The recorded pipe position information can be read by the reading unit 30 together with the pipe identification information described above.

As shown in FIG. 1, the wireless IC tag 20 may include a physical quantity sensor 22 that acquires physical quantity information indicating the physical quantity of the fluid 3 flowing through the pipe 1 (see FIG. 5). For example, the physical quantity sensor 22 is configured to measure a physical quantity and may be connected to the IC chip of the wireless IC tag 20 . Examples of physical quantities include pressure values, flow values and temperature values. The physical quantity sensor 22 may be arranged on the inner surface of the pipe 1 . When the wireless IC tag 20 includes the physical quantity sensor 22 , the wireless IC tag 20 may be fixed to the inner surface of the pipe 1 . In this embodiment, the physical quantity sensor 22 includes a pressure sensor, a flow rate sensor, and a temperature sensor. The pressure sensor measures the pressure value of the fluid 3 flowing through the pipe 1, and pressure information indicating the measured pressure value is recorded in the IC chip. The flow rate sensor measures the flow rate value of the fluid 3 flowing through the pipe 1, and the flow rate information indicating the measured flow rate value is recorded in the IC chip. The temperature sensor measures the temperature value of the fluid 3 flowing through the pipe 1, and the temperature information indicating the measured temperature value is recorded in the IC chip. The wireless IC tag 20 in this embodiment may be an active tag containing a battery (not shown).

The reading unit 30 is configured to wirelessly read pipe identification information, pipe position information, and physical quantity information from the wireless IC tag 20 . For example, the reading unit 30 may be configured to irradiate radio waves 2 and read each piece of information recorded on the wireless IC tag 20 . The reading unit 30 may include the portable reading device 31 shown in FIG. 3, or may include the stationary reading device 32 shown in FIGS. In this embodiment, an example in which the reading unit 30 includes a portable reading device 31 and a stationary reading device 32 will be described. The portable reading device 31 is a reading device that can be carried by the operator 4 (see FIG. 3), and may be used in the receiving process described later. The stationary reading device 32 is a reading device installed at a predetermined position, and may be used in the positioning process, the pressure resistance process, and the system test run process, which will be described later. The portable reader 31 and the stationary reader 32 are configured to irradiate radio waves 2 and read each piece of information from the wireless IC tag 20 .

As shown in FIG. 1, the reading unit 30 may have a communication function. Accordingly, the reading unit 30 can transmit the read pipe identification information, pipe position information, and physical quantity information to the determination unit 40 . More specifically, the above-described portable reader 31 may be composed of, for example, a portable terminal having a communication function. Various information read by the portable reader 31 is transmitted to the determination unit 40 via the Internet 5 . The stationary reader 32 described above may similarly have a communication function. Various information read by the stationary reader 32 is transmitted to the determination unit 40 via the Internet 5 . A VPN (Virtual Private Network) connection may be used for connection to the Internet 5 .

The determination unit 40 is configured to perform determination based on the pipe identification information, pipe position information, and physical quantity information read by the reading unit 30 . The determination unit 40 is configured to determine at least one of whether or not the receiving work for the pipe 1 has been completed and whether or not the alignment work for the pipe 1 has been completed. there is The determination unit 40 according to the present embodiment determines both whether or not the receiving work for the pipe 1 has been completed and whether or not the positioning work for the pipe 1 has been completed. Pipe identification information, pipe position information, and physical quantity information are transmitted from the reading unit 30 to the determination unit 40 . The determination unit 40 may be configured as a device having the determination function described here. For example, the determination unit 40 may be configured by a computer, a server, or the like.

Based on the pipe identification information read by the reading unit 30, the determination unit 40 can determine whether or not the receiving work for the pipe 1 has been completed. More specifically, the determination unit 40 may have acceptance identification information of the pipe 1 scheduled for acceptance work. The acceptance identification information may be identification information obtained from the manufacturer of the pipe 1 . For example, the identification information of the manufactured pipe 1 is transmitted to the determination unit 40 from the manufacturing management system owned by the manufacturer of the pipe 1 and recorded as the acceptance identification information. The acceptance identification information is the pipe identification information of the pipe 1 to be received, but a different term from the pipe identification information recorded in the wireless IC tag 20 is used for clarity of explanation. The determining unit 40 compares the pipe identification information with the receiving identification information when determining the completion of the receiving work for the pipe 1, and determines that the receiving work is completed when the pipe identifying information corresponding to the receiving identification information is obtained from the reading unit 30. judge.

Based on the pipe identification information and the pipe position information read by the reading unit 30, the determination unit 40 can determine whether or not the alignment work of the pipe 1 has been completed. More specifically, the determination unit 40 may have a plurality of pieces of installation position information indicating the installation position of each pipe 1 scheduled for alignment work. The installation position information may be information based on CAD data created in the design process, which will be described later. The installation position information is set for each pipe 1 and is associated with the design identification information in the CAD data. The design identification information is pipe identification information recorded as CAD data when the pipe 1 is designed. The design identification information is the pipe identification information of the pipe 1 at the time of design, but a different term from the pipe identification information recorded in the wireless IC tag 20 is used for clarity of explanation. When judging the completion of the alignment work, the judgment unit 40 collates the pipe position information of the pipe 1 with the installation position information corresponding to the pipe position information, and determines whether each pipe 1 to be worked is positioned at the installation position. If there is, it is determined that the alignment work is completed. At this time, the determination unit 40 collates the pipe position information and the installation position information associated with the same design identification information as the pipe identification information associated with this pipe position information. All aligned pipes 1 are placed at the installation positions indicated by the corresponding installation position information.

The determination unit 40 may be configured to check the progress of the pipe installation work based on a preset schedule when determining that the alignment work is completed. The progress confirmation result may be displayed on the display unit 50 .

The determination unit 40 may determine whether the alignment work is completed for each pipe 1 . In this case, when the alignment work for at least one of the pipes 1 scheduled for the alignment work is completed, it may be determined that the alignment work for the pipe 1 has been completed. For example, when the alignment work for some of the pipes 1 scheduled for the alignment work is completed, it is determined that the alignment work for these pipes 1 has been completed, and the alignment work for the remaining pipes 1 is not completed. You can judge. The result determined in this manner may be displayed on the display unit 50 .

Based on the physical quantity information read by the reading unit 30, the determination unit 40 may determine whether or not the physical quantity of the fluid flowing through the pipe 1 is normal at the time of operation confirmation. More specifically, the determination unit 40 may have target physical quantity information indicating a target physical quantity of the fluid 3 flowing through the pipe 1 . When determining whether or not the physical quantity is normal, the determination unit 40 calculates the difference between the physical quantity of the fluid 3 based on the physical quantity information and the target physical quantity based on the target physical quantity information, and determines whether this difference is equal to or less than the threshold. If the difference is equal to or less than the threshold, it is determined to be normal. Examples of operation confirmation include confirmation of the pressure value in the pressure resistance process, which will be described later, and confirmation of the flow rate value and the temperature value in the system trial operation process. In the pressure resistance step, it may be determined whether the pressure is normal as the determination of whether the physical quantity is normal. In the system test run step, determinations as to whether the physical quantity is normal may include determination as to whether the flow rate is normal and determination as to whether the temperature is normal.

For example, in the pressure resistance process described later, the determination unit 40 determines the difference between the pressure value of the fluid 3 based on the pressure information as an example of the physical quantity information and the target pressure value based on the target pressure information as an example of the target physical quantity information. It is determined whether this difference is equal to or less than the threshold. If this difference is equal to or less than the threshold, the pressure is determined to be normal. For example, in the system trial operation process described later, the determination unit 40 determines the difference between the flow rate value of the fluid 3 based on the flow rate information as an example of the physical quantity information and the target flow rate value based on the target flow rate information as an example of the target physical quantity information is calculated, and it is determined whether or not this difference is equal to or less than the threshold. If this difference is equal to or less than the threshold, it is determined that the flow rate is normal. For example, in the system trial operation process, the determination unit 40 calculates the difference between the temperature value of the fluid 3 based on the temperature information as an example of the physical quantity information and the target temperature value based on the target temperature information as an example of the target physical quantity information. Then, it is determined whether or not this difference is equal to or less than the threshold. If this difference is equal to or less than the threshold, the temperature is determined to be normal.

The display unit 50 displays the result of determination by the determination unit 40 . The display unit 50 may be configured as a device having the display function described here. For example, the display unit 50 may be configured by a display.

More specifically, the display unit 50 displays that the receiving work is completed when the determining unit 40 determines that the receiving work is completed in the receiving process. In the alignment process, the display unit 50 displays that the alignment work is completed when the determination unit 40 determines that the alignment work is completed. The display unit 50 may display the determination result by the determination unit 40 for each pipe 1 when the determination unit 40 determines completion of alignment work for each pipe 1 .

The display unit 50 may display the physical quantity of the fluid 3 flowing through the pipe 1 based on the physical quantity information. For example, the display unit 50 may display a pressure value based on pressure information, a flow rate value based on flow rate information, or a temperature value based on temperature information. Moreover, the display unit 50 may display the determination result of the physical quantity of the fluid 3 . For example, the display unit 50 may display that the pressure is normal when the determination unit 40 determines that the pressure of the fluid 3 is normal. The display unit 50 may display that the flow rate is normal when the determination unit 40 determines that the flow rate of the fluid 3 is normal, and the determination unit 40 determines that the temperature of the fluid 3 is normal. may indicate that the temperature is normal.

The recording unit 60 may record the determination result by the determination unit 40 . The recording unit 60 may be configured as a device having the recording function described here. For example, the recording unit 60 may be configured by a memory, hard disk, or the like.

The recording unit 60 records the result of determination by the determination unit 40 . More specifically, the recording unit 60 records the work completion when the determination unit 40 determines that the work is completed. For example, when the determining unit 40 determines that the receiving work is completed in the receiving process, the completion of the receiving work is recorded. Record that the work has been completed. The recording unit 60 may record the determination result by the determination unit 40 for each pipe 1 when the determination unit 40 determines whether the work is completed for each pipe 1 .

The recording unit 60 may record the physical quantity of the fluid 3 flowing through the pipe 1 based on the physical quantity information. For example, the recording unit 60 may record pressure values based on pressure information, may record flow values based on flow information, and may record temperature values based on temperature information. Also, the recording unit 60 may record the determination result of the physical quantity of the fluid 3 . For example, the recording unit 60 may record that the pressure is normal when the determination unit 40 determines that the pressure of the fluid 3 is normal. The recording unit 60 may record that the flow rate is normal when the determination unit 40 determines that the flow rate of the fluid 3 is normal, and the determination unit 40 determines that the temperature of the fluid 3 is normal. If so, the temperature may be recorded as normal.

Next, a piping installation management method according to the present embodiment will be described with reference to FIGS. 2 to 5. FIG. The piping installation management method according to this embodiment may be used in several steps of the piping installation work shown in FIG.

As shown in FIG. 2, the pipe installation work includes a design process, a manufacturing process, a receiving process, a storage process, a hanging process, an alignment process, a connection process, a progress management process, and a pressure resistance process. , and a system commissioning step.

<<Design Process>>
In the design process, a plurality of pipes 1 to be installed are designed. The installation position of each pipe 1 determined by the design of the pipe 1 is recorded as CAD data. Each installation position recorded as CAD data is used as installation position information in the alignment process to be described later. Each pipe 1 installed may be assigned an identification number at design time. The identification number is associated with the installation position information as design identification information. The fixed position of the wireless IC tag 20 to each pipe 1 may be determined at the time of design. The installation position may be a position where the position detection terminal 21, which will be described later, is fixed.

<<Manufacturing Process>>
In the manufacturing process, the pipe 1 designed in the design process is manufactured. The wireless IC tag 20 may be fixed to each pipe 1 in the manufacturing process. The wireless IC tag 20 may be fixed at a fixed position determined during design. An identification number assigned to the corresponding pipe 1 is recorded in the wireless IC tag 20 as pipe identification information. The position detection terminal 21 and the physical quantity sensor 22 described above may be fixed together with the wireless IC tag 20 to each pipe 1 .

<<Receiving Process>>
In the receiving process, as shown in FIG. 3, the manufactured pipe 1 is received. The pipe 1 may be positioned in a desired receiving area, and the pipe 1 to be received may be distributed. In the receiving process, the receiving work may be managed using the piping installation management system 10 described above. In this case, the receiving process may have a reading process, a judgment process, and a display process. The piping installation management system 10 may recognize that the piping installation work has proceeded to the acceptance process based on an input from the operator 4 who confirmed the completion of the manufacturing process.

<Reading process>
In the reading process, the pipe identification information of each pipe 1 is read from the wireless IC tag 20 fixed to each pipe 1 . For example, the operator 4 carries the portable reading device 31 and goes to the position where the pipe 1 to be received is placed. At that position, radio waves 2 are emitted from the portable reader 31 . As a result, pipe identification information is read from the wireless IC tag 20 fixed to each pipe 1 . The pipe identification information that has been read is transmitted to the determination unit 40 via the Internet 5 . In the reading process of the receiving process, the pipe position information may also be read from the wireless IC tag 20 and transmitted to the determination unit 40 .

<Judgment process>
In the determination step, it is determined whether or not the receiving operation of the pipe 1 is completed based on the read pipe identification information. More specifically, the acceptance identification information of each pipe 1 scheduled for acceptance work is transmitted in advance from the manufacturer of the pipe and recorded in the determination unit 40 . Each acceptance identification is the identification number described above. The determination unit 40 collates the pipe identification information of each pipe 1 with the received identification information, and determines whether or not the pipe identification information corresponding to the received identification information has been read from the portable reading device 31 . When the piping identification information corresponding to the reception identification information is read from the portable reading device 31, it is determined that the reception work is completed because all the piping 1 to be received has been received.

<Display process>
In the display step, the determination result in the determination step is displayed. More specifically, when it is determined that the receiving work is completed in the determining step, the message "receiving work completed" is displayed.

Thus, the receiving process is completed. The next storage process is started by the operator 4 who confirmed the display of completion of the receiving work. The confirmation of the completion of the receiving work may be performed for each pipe. In this case, the determination result for each pipe 1 may be displayed on the display unit 50 .

<<Storage process>>
In the storage process, the pipe 1 for which it has been confirmed that the receiving work has been completed is stored in a predetermined storage area until the next hoisting process starts. In the storage process, storage management may be performed using the piping installation management system 10 described above. The piping installation management system 10 may recognize that the piping installation work has proceeded to the storage process based on an input from the operator 4 who confirmed the display of completion of the receiving work. In the storage process, for example, it may be confirmed whether or not the pipe 1 continues to be stored in the storage area. In this case, the reading process, determination process, and display process in the receiving process described above may be performed.

In the reading process of the storage process, the reading unit 30 reads the pipe identification information of the pipe 1 and the pipe position information of the pipe 1 from the wireless IC tag 20 . In the determination step, it is determined whether or not the pipe 1 is stored in the storage area based on the read pipe identification information and pipe position information. More specifically, storage area information indicating the storage area of the pipe 1 is recorded in advance in the determination unit 40 . Based on the pipe position information, it is confirmed whether the pipe 1 corresponding to the reception identification information described above is located in the storage area. Each pipe 1 may be arranged at any position in the storage area as long as it is arranged in the storage area.

<<Hanging process>>
In the hanging process, as shown in FIG. 4, the pipe 1 stored in the storage area is moved to the installation position. When the pipe 1 is installed inside the building, the pipe 1 is hung from the steel frame 6 of the building by a hanging tool 7 such as a wire.

<<Positioning Process>>
In the alignment process, as shown in FIG. 4, each suspended pipe 1 is aligned. Each pipe 1 is positioned at a desired installation position. In the alignment process, the alignment work may be managed using the piping installation management system 10 described above. In this case, the alignment process may include a reading process, a determination process, and a display process. The pipe installation management system 10 may recognize that the pipe installation work has proceeded to the alignment process based on an input from the operator 4 who has confirmed the completion of the hanging process.

<Reading process>
In the reading process, the pipe identification information of the pipe 1 and the pipe position information of the pipe 1 are read from the wireless IC tag 20 fixed to each pipe 1 . For example, radio waves 2 are emitted from a stationary reading device 32 installed in advance near the installation position. Although FIG. 4 shows an example of using a plurality of stationary readers 32, the number of stationary readers 32 may be one, and the number of stationary readers 32 may be one. It can be set arbitrarily according to the range. As a result, pipe identification information and pipe position information are read from the wireless IC tag 20 fixed to each pipe 1 . The read pipe identification information and pipe position information are transmitted to the determination unit 40 via the Internet 5 .

<Judgment process>
In the determination step, it is determined whether or not the alignment work for the pipe 1 has been completed based on the read pipe identification information and pipe position information. More specifically, the installation position information indicating the installation position of each pipe 1 is transmitted in advance from the CAD system and recorded in the determination unit 40 in association with the design identification information. The determination unit 40 collates the pipe position information of each pipe 1 with installation position information corresponding to the pipe position information, and judges whether or not each pipe 1 is positioned at the installation position. At this time, the determination unit 40 collates the pipe position information and the installation position information associated with the same design identification information as the pipe identification information associated with this pipe position information. Then, the determination unit 40 determines that the alignment work is completed when the pipe 1 for which the alignment work is scheduled is positioned at the installation position. In this case, all the pipes 1 scheduled for alignment work are located at corresponding installation positions.

<Display process>
In the display step, the determination result in the determination step is displayed. More specifically, when it is determined that the alignment work has been completed in the determining step, the completion of the alignment work is displayed.

Thus, the alignment process is completed. The next connection process is started by the operator 4 who confirms the indication of the completion of the alignment work. Note that the position of the pipe 1 may be checked for each pipe 1 in the alignment process. In this case, the determination result for each pipe 1 may be displayed on the display unit 50 .

<<Connection process>>
In the connecting step, adjacent pipes 1 are connected. Moreover, each pipe 1 is fixed to the steel frame 6 of the building.

<<Progress status confirmation process>>
In the progress confirmation step, the progress of the pipe installation work is confirmed based on a preset schedule. The progress confirmation result is displayed on the display unit 50 .

In the progress checking process, the progress may be managed using the piping installation management system 10 described above. The pipe installation management system 10 may recognize that the pipe installation work has proceeded to the progress confirmation step based on an input from the operator 4 who has confirmed the completion of the connection step. For example, when determining that the alignment work is completed, the determining unit 40 determines the timing of completion of the alignment work set in the schedule and the timing of completion of the alignment work in the alignment process described above. A difference may be calculated. This makes it possible to check whether the progress of the pipe installation work is behind or ahead of the initial schedule. It is also possible to confirm the degree of delay or the degree of advance according to the calculated time difference. Depending on the confirmation result of the progress, the execution timing of the following pressure resistance process may be adjusted. The progress confirmation process may be performed before the connection process, or may be performed in parallel with the connection process.

<<Pressure pressure process>>
In the pressure resistance process, as shown in FIG. 5, the pressure resistance of the pipe 1 is confirmed by flowing the fluid 3 into the pipe 1 . By checking the pressure of the fluid 3, the presence or absence of leakage of the fluid 3 is confirmed. The fluid 3 may be the same fluid 3 that flows in the pipe 1 during operation and trial operation. The fluid 3 may be any fluid that can flow through the pipe 1, such as cooling water, hot water, steam, or cooling air. In the pressure resistance process, the pressure resistance confirmation may be performed using the piping installation management system 10 described above. In this case, the withstand voltage process may include a reading process, a determination process, and a display process. The pipe installation management system 10 may recognize that the pipe installation work has progressed to the pressure-resistant process based on an input from the operator 4 who confirmed the display of the confirmation result of the progress status. The pressure resistance process is initiated by the operator 4 causing the fluid 3 to flow through the pipe 1 prior to the reading process.

<Reading process>
In the reading process, pipe identification information and pressure information of each pipe 1 are read from the wireless IC tag 20 fixed to each pipe 1 . For example, the radio waves 2 are emitted from the stationary reader 32 described above. As a result, pressure information is read from the wireless IC tag 20 fixed to each pipe 1 . The read piping identification information and pressure information are transmitted to the determination unit 40 via the Internet 5 . In the reading process of the pressure resistance process, the pipe identification information may also be read from the wireless IC tag 20 and transmitted to the determination unit 40 .

<Judgment process>
In the determination step, it is determined whether or not the pressure of the fluid 3 flowing through each pipe 1 is normal based on the read pipe identification information and pressure information. More specifically, target pressure information indicating the target pressure value of the fluid 3 is recorded in advance in the determination unit 40 . A target pressure value is common to each pipe 1 . The determination unit 40 calculates the difference between the pressure value based on the pressure information of each pipe 1 and the target pressure based on the target pressure information, and determines whether or not this difference is equal to or less than a desired threshold value. Then, the determination unit 40 determines that the pressure of the fluid 3 is normal when the difference between the pressure value of the fluid 3 and the target pressure value is equal to or less than the threshold.

<Display process>
In the display step, the determination result in the determination step is displayed. More specifically, when it is determined that the pressure of the fluid 3 is normal in the determination step, the pressure is displayed as normal. Moreover, the pressure value for each pipe 1 may be displayed on the display unit 50 based on the pressure information transmitted to the determination unit 40 . In addition, the pressure values displayed on the display unit 50 do not have to display the pressure values of all the pipes 1 .

The pressure resistance process is completed after the pressure of the fluid 3 is applied to the pipe 1 for a predetermined time. After the pressure resistance process is completed, the next system test run process is started by the operator 4 .

<<System test run process>>
In the system test run step, as shown in FIG. 5, the system in which the pipe 1 is installed is tested by flowing the fluid 3 through the pipe 1 . At this time, the flow rate and temperature of the fluid 3 flowing through the pipe 1 are confirmed. In the system trial run process, the system trial run may be performed using the piping installation management system 10 described above. In this case, the system trial operation process may have a reading process, a determination process, and a display process. The piping installation management system 10 may recognize that the piping installation work has progressed to the system trial operation process based on an input from the operator 4 who has confirmed the display of the determination result of the pressure resistance process. The system commissioning process is initiated by the operator 4 causing the fluid 3 to flow through the pipe 1 prior to the reading process.

<Reading process>
In the reading process, pipe identification information, flow rate information, and temperature information of each pipe 1 are read from the wireless IC tag 20 fixed to each pipe 1 . For example, the radio waves 2 are emitted from the stationary reader 32 described above. As a result, identification information, flow rate information and temperature information are read from the wireless IC tag 20 fixed to each pipe 1 . The read identification information, flow rate information and temperature information are transmitted to the determination section 40 via the Internet 5 .

<Judgment process>
In the determination step, it is determined whether or not the flow rate value and temperature value of the fluid 3 flowing through each pipe 1 are normal based on the read pipe identification information, flow rate information and pressure information. More specifically, target flow information indicating a target flow rate value of the fluid 3 and target temperature information indicating a target temperature value are recorded in advance in the determination unit 40 . A target flow rate value and a target temperature value are common to each pipe 1 . The determination unit 40 calculates the difference between the flow rate value based on the flow rate information of each pipe 1 and the target flow rate value based on the target flow rate information, and determines whether or not this difference is equal to or less than a desired threshold value.
