Description

The present invention relates to a steam trap management system for managing the state of a steam trap.

In a plant equipped with a steam piping system, condensate (drain) may occur in the piping system due to heat exchange or heat dissipation. If this condensate stays in the piping system, it will cause a decrease in operating efficiency. Therefore, in general, a steam trap should be installed in the appropriate place in the piping system, and the condensate should be discharged to the outside of the piping system by this steam trap. I have to.

If the sealing performance of the steam trap is impaired due to deterioration over time or malfunction, steam in the steam piping system leaks to the outside through the steam trap, resulting in unnecessary steam loss. Therefore, the work of checking the state of the steam trap is performed regularly, such as once a year.

The following Patent Document 1 discloses a measuring device and a diagnostic device for diagnosing the state of a steam trap. The measuring device is a portable measuring device, the diagnostic device is a tablet terminal, a notebook computer, or the like, and the measuring device and the diagnostic device can communicate wirelessly with each other. The measuring device includes a temperature sensor that measures the surface temperature of each steam trap, a vibration sensor that measures the vibration intensity of each steam trap, a storage unit that stores the temperature sensor and the measurement data output from the vibration sensor, and the measurement thereof. It includes a communication unit that transmits data to the diagnostic device and a display unit. The diagnostic device diagnoses the state (normal or abnormal) of each steam trap based on the measurement data received from the measuring device, and transmits diagnostic data indicating the result of the diagnosis to the measuring device. The measuring device displays the diagnosis result for each steam trap on the display unit based on the diagnostic data received from the diagnostic device.

In addition, since thousands to tens of thousands of steam traps may be installed in a large plant, the management ledger is used as management information for managing the status of such a huge number of steam traps. Sometimes.

The following Patent Document 2 describes identification information such as a serial number (trap ID), attribute information such as a manufacturer name and model, and operation information such as working pressure and set temperature for each of all steam traps to be managed. , A management ledger that describes the diagnosis results of past periodic inspections is disclosed.

Japanese Unexamined Patent Publication No. 2018-84418 Japanese Patent No. 2954183

Since the absolute position of the steam trap is not managed in the management ledger disclosed in Patent Document 2, the worker performing the periodic inspection may specify the absolute position of each steam trap depending on the information that can be obtained from the management ledger. Can not. Therefore, the worker needs to specify the absolute position of each steam trap by referring to the area map information or the like indicating the installation location of the steam trap separately from the management ledger, which is inefficient.

In addition, steam traps may be added or removed depending on the operating status of the plant or the occurrence of steam leaks. Here, if the information on the addition or removal of the steam trap is not correctly reflected in the area map information, it may be difficult to manage the steam trap accurately because the inspection omission of the steam trap may occur.

According to this aspect, in each of the diagnostic device, the data processing device, and the server device, the diagnostic data of each steam trap is associated with the absolute position information. Therefore, since the diagnostic device can specify the absolute position of each steam trap based on the management information, the operator does not need to refer to the area map information or the like indicating the installation location of the steam trap. In addition, even if the steam trap is added or removed and the information is not correctly reflected in the management information, the worker can refer to the absolute location information contained in the management information to make the steam trap. It can be determined that it has been added or removed. As a result, work efficiency in inspection work can be improved, and steam traps can be managed accurately.

The diagnostic order of the plurality of steam traps is set so that the movement distance required for the movement is the shortest.

According to this aspect, the worker can improve the work efficiency because the moving distance is the shortest by sequentially diagnosing a plurality of steam traps according to the diagnosis order set by the order setting unit.

In the above aspect, in the management information, attribute information including each type of the plurality of steam traps is described in association with the absolute position information, and the diagnostic device further includes a control unit and a display unit. However, the control unit can display the attribute information on the display unit in association with the absolute position information of each of the plurality of steam traps.

According to this aspect, the display unit of the diagnostic apparatus displays attribute information including the type of the steam trap in association with the absolute position information of each steam trap. Therefore, even if a steam trap is exchanged and the exchange information is not reflected in the management information, the operator can compare the model displayed on the display with the actual steam trap model. Can determine that the steam trap has been replaced. Then, by updating the management information so that the exchange information is reflected, it becomes possible to accurately manage the steam trap by the updated management information.

FIG. 2 is a sequence diagram showing a processing flow in the steam trap management system 100.

<Preparation for regular inspection>
The worker creates the management ledger 91 by using the data processing device 2 before carrying out the periodic inspection this time. The process of creating the management ledger 91 is executed by the management ledger creation unit 51. The management ledger creation unit 51 includes a position information setting unit 61 and an order setting unit 62 as its functions.

FIG. 3 is a diagram showing the processing contents of the position information setting unit 61 and the order setting unit 62. In an area AR such as a plant equipped with a steam piping system, a plurality of steam traps 50 are installed at appropriate positions in the piping system. In FIG. 3, for the sake of simplicity of explanation, only nine steam traps 50 to which trap numbers T1 to T9 are assigned as identification information (ID) are shown.

The position information setting unit 61 acquires area map information indicating the installation location (absolute position) of each steam trap 50 in the area AR from the management terminal of the plant or the like. When the management terminal is connected to the communication network 4, the location information setting unit 61 acquires area map information from the management terminal via the communication network 4 and the communication unit 46.

Based on the acquired area map information, the position information setting unit 61 divides the area map information into a plurality of grids G arranged in a plurality of rows and a plurality of columns so that each grid G includes a maximum of one steam trap 50. In the example of FIG. 3, the area map information is divided into 81 grids G of 9 rows × 9 columns.

The position information setting unit 61 sets the absolute position information of each steam trap 50 by using the row numbers Y1 to Y9 and the column numbers X1 to X9 assigned to each row and each column. For example, the absolute position information of the steam trap 50 of the trap number T1 is the coordinates (X1, Y1), and the absolute position information of the steam trap 50 of the trap number T5 is the coordinates (X6, Y4).

As a result, the management ledger creation unit 51 can easily and accurately set the absolute position information I1 of each steam trap 50 in the area map information.

The order setting unit 62 has the diagnosis order of the plurality of steam traps 50 so that the movement distance required for the movement for sequentially diagnosing the plurality of steam traps 50 is the shortest based on the position coordinates of each steam trap 50 in the area map information. To set. That is, the order setting unit 62 searches for the shortest path connecting all the steam traps 50 with a single stroke, starting from one designated steam trap 50. As the shortest path search algorithm used by the order setting unit 62, any algorithm such as Dijkstra's algorithm or Bellman-Ford algorithm can be used. In the example of FIG. 3, the diagnostic order of the plurality of steam traps 50 is set in the order of trap numbers T1 → T4 → T5 → T7 → T9 → T8 → T6 → T3 → T2.

As a result, the operator diagnoses the plurality of steam traps 50 in order according to the diagnosis order set by the order setting unit 62, so that the moving distance is the shortest, so that the work efficiency can be improved.

The management ledger creation unit 51 creates the management ledger 91 by arranging the information related to the plurality of steam traps 50 in the order of the diagnosis order set by the order setting unit 62 (step S1). The management ledger creation unit 51 stores the created management ledger 91 in the storage unit 45 (step S2).

FIG. 4 is a diagram showing an example of the management ledger 91. In the management ledger 91, identification information I2, attribute information I3, operation information I4, and diagnosis result information I5 are described in association with the absolute position information I1 for each of the plurality of steam traps 50.

In the example of FIG. 4, the absolute position information I1 is the coordinates represented by using the row numbers Y1 to Y9 and the column numbers X1 to X9. The identification information I2 is trap numbers T1 to T9. The attribute information I3 includes the manufacturer name and model name of the steam trap 50. However, the attribute information I3 may further include product number information that is more detailed than the model name. The operation information I4 includes the working pressure and the set temperature.

When the identification information I2, the attribute information I3, and the operation information I4 regarding each steam trap 50 are included in the area map information, the management ledger creation unit 51 can extract these information from the area map information. Is. Alternatively, when these information are not included in the area map information, these information may be input from the operation unit 43 to the control unit 41 in response to keyboard input by the operator or the like.

The diagnosis result information I5 includes the inspection date and the diagnosis result. At the stage of preparation before the regular inspection is carried out, the inspection date and diagnosis result items are blank. The order of the plurality of steam traps 50 in the management ledger 91 is not limited to the diagnosis order, and may be the descending order or the ascending order of the trap numbers.

The communication unit 46 transmits the management ledger 91 created by the management ledger creation unit 51 to the server device 3 (step S3). In the server device 3, the communication unit 72 receives the management ledger 91 transmitted from the communication unit 46. The control unit 71 stores the management ledger 91 received by the communication unit 72 in the storage unit 73 (step S4).

Further, the communication unit 42 transmits the management ledger 91 created by the management ledger creation unit 51 to the diagnostic apparatus 1 (step S5). In the diagnostic apparatus 1, the communication unit 16 receives the management ledger 91 transmitted from the communication unit 42.

Display on. As a result, the worker can recognize the diagnostic order of the plurality of steam traps 50 installed in the area AR and the absolute position information I1, the identification information I2, and the attribute information I3 of each steam trap 50. .. When the worker carries the data processing device 2, the management ledger 91 may be displayed on the display unit 44 of the data processing device 2. Since the display unit 44 usually has a larger screen than the display unit 14, displaying the management ledger 91 on the display unit 44 improves visibility by the operator.

The operator moves to the installation location of the steam trap 50, which is the measurement target this time, according to the diagnosis order and the absolute position that can be recognized from the displayed management ledger 91. Further, the operator selects one steam trap 50 to be measured this time from the plurality of steam traps 50 included in the management ledger 91 by operating the switch of the operation unit 13. As a result, the selection information of the steam trap 50 is input from the operation unit 13 to the control unit 11.

Next, the operator presses the probe (not shown) of the diagnostic device 1 against the steam trap 50 to be measured. As a result, measurement data (temperature data and vibration data) are input from the measurement unit 12 to the control unit 11. The diagnosis unit 31 diagnoses the state of the steam trap 50 to be measured based on the measurement data input from the measurement unit 12.

The control unit 11 inputs diagnostic data indicating the result of the diagnosis by the diagnostic unit 31 to the display unit 14. As a result, the diagnosis result regarding the steam trap 50 to be measured is displayed on the display unit 14.

Further, the control unit 11 creates the diagnosis result information I5 (inspection date and diagnosis result) based on the diagnosis data, and stores the diagnosis result information I5 in the management ledger 91 stored in the storage unit 15. Add to the corresponding part specified by (step S8). By adding the diagnosis result information I5 to the corresponding portion of the management ledger 91, the diagnosis result information I5 of each steam trap 50 is associated with the absolute position information I1 of each steam trap 50 and stored in the storage unit 15. It will be.

Further, the control unit 11 inputs the absolute position information I1 and the diagnosis result information I5 of each steam trap 50 to the communication unit 16. The communication unit 16 transmits the input absolute position information I1 and diagnosis result information I5 to the data processing device 2 (step S9).

The communication unit 42 of the data processing device 2 receives the absolute position information I1 and the diagnosis result information I5 transmitted from the communication unit 16.

The acquisition unit 52 acquires the absolute position information I1 and the diagnosis result information I5 received from the diagnostic device 1 by the communication unit 42 from the communication unit 42.

The control unit 41 updates the management ledger 91 stored in the storage unit 45 based on the absolute position information I1 and the diagnosis result information I5 acquired by the acquisition unit 52 (step S10). Specifically, the control unit 41 identifies the diagnosis result information I5 acquired by the acquisition unit 52 by the absolute position information I1 acquired by the acquisition unit 52 in the management ledger 91 stored in the storage unit 45. Add to the place. By adding the diagnosis result information I5 to the corresponding portion of the management ledger 91, the diagnosis result information I5 of each steam trap 50 is associated with the absolute position information I1 of each steam trap 50 and stored in the storage unit 45. It will be.

Further, the control unit 41 inputs the absolute position information I1 and the diagnosis result information I5 acquired by the acquisition unit 52 to the communication unit 46. The communication unit 46 transmits the input absolute position information I1 and diagnosis result information I5 to the server device 3 via the communication network 4 (step S11).

The communication unit 72 of the server device 3 receives the absolute position information I1 and the diagnosis result information I5 transmitted from the communication unit 46.

The acquisition unit 80 acquires the absolute position information I1 and the diagnosis result information I5 received from the data processing device 2 by the communication unit 72 from the communication unit 72.

The management ledger updating unit 81 updates the management ledger 91 stored in the storage unit 73 based on the absolute position information I1 and the diagnosis result information I5 acquired by the acquisition unit 80 (step S12). Specifically, the management ledger updating unit 81 identifies the diagnosis result information I5 acquired by the acquisition unit 80 by the absolute position information I1 acquired by the acquisition unit 80 among the management ledger 91 stored in the storage unit 73. Add to the corresponding part.

It will be. The management ledger update unit 81 executes the same processing as described above for all the steam traps 50 managed by the management ledger 91.

FIG. 5 is a diagram showing an example of the management ledger 91. The addition of the diagnosis result information I5 has been completed for all the steam traps 50 managed by the management ledger 91. As a result, the update process of the management ledger 91 accompanying this periodic inspection is completed. By executing the same update process every time the periodic inspection is performed, information on the periodic inspections performed in the past is accumulated in the management ledger 91 and managed by the server device 3.

The analysis unit 82 executes various analysis processes based on the management ledger 91 for which the update process has been completed, and stores the analysis data 92 obtained by the analysis process in the storage unit 73 (step S13). For example, the analysis unit 82 lists the steam traps 50 having an abnormal diagnosis result (steam leakage, drain discharge failure, or blockage) from all the steam traps 50 managed by the management ledger 91. , Create a bad trap list. Further, the analysis unit 82 calculates the defect rate as the ratio of the total number of steam traps 50 having an abnormal diagnosis result to the total number of steam traps 50 managed by the management ledger 91. Further, the analysis unit 82 calculates the total leakage amount and the loss amount due to the total leakage amount of each steam trap 50 in which the steam leakage has occurred. Further, when long-term information for several years or more is accumulated in the management ledger 91, the analysis unit 82 aggregates the time-series transitions of these analysis results, and the aggregated result is timed.

Even if the worker arrives at the position indicated by the coordinates (X8, Y3) by referring to the management ledger 91, the worker cannot find the steam trap 50 having the trap number T7 which should be there.

In this case, the operator corrects the management ledger 91 by the operation unit 13. When a correction signal is input from the operation unit 13 to the control unit 11 in response to a switch operation by the operator, the control unit 11 deletes the item corresponding to the steam trap 50 of the trap number T7, which is a management ledger. The correction process of 91 is executed.

Further, when the operator arrives at the position indicated by the coordinates (X8, Y6) by referring to the management ledger 91, the operator recognizes that there is a steam trap 50 having a trap number T11 instead of the trap number T8. The operator can determine that the steam trap 50 has been replaced by comparing the model of the steam trap 50 shown in the management ledger 91 with the model of the steam trap 50 actually installed.

In this case, the operator corrects the management ledger 91 by the operation unit 13. When a correction signal is input from the operation unit 13 to the control unit 11 in response to a switch operation by an operator or the like, the control unit 11 sets an item corresponding to the steam trap 50 of the trap number T8 to the steam trap 50 of the trap number T11. The correction process of the management ledger 91 of the content to be overwritten with the item corresponding to is executed.

Further, when the operator notices that the steam trap 50 of the trap number T10 is added while moving from the steam trap 50 of the trap number T6 to the steam trap 50 of the trap number T3, the operation unit 13 The management ledger 91 is modified by.

When a correction signal is input from the operation unit 13 to the control unit 11 in response to a switch operation by the operator, the control unit 11 places the trap number on the line following the line corresponding to the steam trap 50 of the trap number T6. The correction process of the management ledger 91 of the content of adding the item corresponding to the steam trap 50 of T10 is executed.

The diagnostic device 1 transmits the modified contents of the management ledger 91 to the data processing device 2 and the server device 3. The data processing device 2 and the server device 3 modify the management ledger 91 stored in each of them so as to reflect the received modification contents.

FIG. 7 is a diagram showing an example of the management ledger 91. By modifying the management ledger 91, all the changes of the steam trap 50 described above are reflected.

As described above, the display unit 14 of the diagnostic apparatus 1 displays the attribute information I3 including the model of the steam trap 50 in association with the absolute position information I1 of each steam trap 50. Therefore, even if a certain steam trap 50 is exchanged and the exchange information is not reflected in the management ledger 91, the operator can use the model displayed on the display unit 14 and the actual model of the steam trap 50. By comparing, it can be determined that the steam trap 50 has been replaced. Then, by updating the management ledger 91 so that the exchange information is reflected, the steam trap 50 can be accurately managed by the updated management ledger 91.

<Summary>
According to the steam trap management system 100 according to the present embodiment, in the storage unit 73 (management information storage unit) of the server device 3, the diagnosis result information I5 of each steam trap 50 is described in association with the absolute position information I1. Store the management ledger 91. Further, the storage unit 15 (diagnosis data storage unit) of the diagnostic apparatus 1 stores the diagnosis result information I5 of each steam trap 50 in association with the absolute position information I1. Further, the communication unit 46 (transmission unit) of the data processing device 2 transmits the absolute position information I1 and the diagnosis result information I5 of each steam trap 50 acquired from the diagnosis device 1 to the server device 3. Then, the management ledger updating unit 81 (management information updating unit) of the server device 3 updates the management ledger 91 based on the absolute position information I1 and the diagnosis result information I5 of each steam trap 50 received from the data processing device 2. .. As described above, in each of the diagnostic device 1, the data processing device 2, and the server device 3, the diagnosis result information I5 of each steam trap 50 is associated with the absolute position information I1. Therefore, since the diagnostic device 1 can specify the absolute position of each steam trap 50 based on the management ledger 91, the operator does not need to refer to the area map information or the like indicating the installation location of the steam trap 50. Further, even when the steam trap 50 is added or removed and the information is not correctly reflected in the management ledger 91, the worker can refer to the absolute position information I1 included in the management ledger 91. , It can be determined that the steam trap 50 has been added or removed. As a result, the work efficiency in the inspection work can be improved, and the steam trap 50 can be managed accurately.
