Authenticate the legitimacy of the account from which you are sending. If the account is valid, the authority management unit 83 transmits a response signal permitting login from the communication unit 72 to the data processing device 2 via the communication network 4 (step S0B).

Further, the authority management unit 83 determines the authority set for the account by referring to the authority management table 93. In the case of this example, the account is an account of the sales department of Miyawaki Corporation. Therefore, the account has the authority to edit its own account, the authority to newly register the management ledger 91 from the data processing device 2 to the server device 3, and the diagnosis of each steam trap 50 from the data processing device 2 to the server device 3. The authority to upload the result information I5, the authority to edit the management ledger 91, the authority to view the management ledger 91, and the authority to process the data of the management ledger 91 are set.

<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. 4 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. 4, 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. 4, 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. 4, 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. 5 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. 5, 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. The control unit 11 stores the management ledger 91 received by the communication unit 16 in the storage unit 15 (step S6).

At that time, a request signal is input from the operation unit 13 to the control unit 11 in response to a switch operation or the like by the operator, so that the control unit 11 displays the management ledger 91 stored in the storage unit 15 in advance in preparation. 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).
