Description

The present invention relates to a technique for outputting information regarding steam trap replacement.

BACKGROUND ART In facilities such as plants and factories equipped with steam piping systems, condensate (drainage) generated due to heat exchange or heat radiation is discharged to the outside of the piping system using steam traps installed at appropriate locations in the piping system. If the performance of the steam trap is impaired due to aging or malfunction, steam within the piping system will leak to the outside through the steam trap, resulting in unnecessary steam loss. For this reason, on a regular basis, such as once a year, multiple personnel are asked to bring measuring and diagnostic equipment (hereinafter referred to as diagnostic equipment) as disclosed in Patent Document 1, etc., and in one day approximately 1,000 steam traps are collected. The diagnosis is divided among the two.

However, diagnosing steam traps manually by a person in charge using a diagnostic device takes a lot of time. For this reason, some facilities employ a system in which a measuring device is permanently installed in each steam trap, measurement data necessary for diagnosis is transmitted to a server device, and the server device diagnoses each steam trap.

After diagnosing multiple steam traps, we create a report on the diagnosis results, such as a report showing the change in the amount of steam leaked from each steam trap over time, and send the report to the customer who manages the steam trap. present.

Hereinafter, embodiments of the present invention will be described in detail using the drawings. In addition, elements given the same reference numerals in different drawings indicate the same or corresponding elements.

<System configuration>
FIG. 1 is a block diagram showing the configuration of a steam trap management system 100. The steam trap management system 100 includes a diagnostic device 1, an information processing device 2 such as a notebook computer or a tablet terminal, a measuring device 3, and a server device 4 (output device) such as a cloud server.

The diagnostic device 1 and the information processing device 2 can communicate with each other using any communication method such as Bluetooth (registered trademark). The information processing device 2 and the server device 4 can communicate with each other via any communication network 9 such as a public line network or the Internet using any communication method such as IP.

In facilities such as plants and factories equipped with steam piping systems, multiple steam traps are installed at appropriate locations in the piping system to discharge condensate (drainage) generated within the piping system to the outside of the piping system. There is. When the performance of the steam trap is impaired due to aging or malfunction, steam within the piping system leaks to the outside through the steam trap, resulting in unnecessary steam loss.

In addition, impurities such as rust and scale that have accumulated in the piping due to the long-term reaction between the steam and the piping material may circulate, causing uneven wear on the steam trap and impairing the performance of the steam trap. Scale is the precipitation of inorganic salt compounds such as calcium, magnesium, and silica contained in steam and condensate flowing into pipes.

For this reason, work to diagnose a plurality of steam traps (hereinafter referred to as "diagnosis work") is performed periodically, such as once a year. Note that the diagnostic work is not limited to regular intervals, but may be performed irregularly. Diagnosis work is divided and performed by multiple workers. Each worker moves around the facility carrying the diagnostic device 1 and uses the diagnostic device 1 to sequentially diagnose one or more steam traps for which he or she is responsible.

If the information processing device 2 such as a notebook computer is allowed to be brought into the facility, the worker can carry the information processing device 2 along with the diagnostic device 1 and diagnose each steam trap in turn. In this case, the diagnostic device 1 can transmit the diagnostic results of each steam trap to the server device 4 via the information processing device 2 and the communication network 9 in real time. On the other hand, if bringing in the information processing device 2 is prohibited, the worker should store the information processing device 2 in a standby area such as a commercial vehicle or on-site office, carry only the diagnostic device 1, and use the The steam traps are sequentially diagnosed by the diagnostic device 1.

For example, the diagnostic device 1 measures the vibration and temperature of a steam trap in response to an operation by an operator. The diagnostic device 1 diagnoses whether the steam trap is in a normal state or a defective state based on vibration and temperature measurement data. The diagnostic device 1 also calculates the amount of steam leakage in the steam trap based on the vibration and temperature measurement data. The diagnostic device 1 diagnoses the state of the steam trap (for example, no leak, small leak, medium leak, large leak, blown out, etc.) based on the calculated amount of steam leak.

The diagnostic results of each steam trap are stored in a memory within the diagnostic device 1. After the worker returns to the waiting area, the diagnostic device 1 sends the diagnostic results of the plurality of steam traps stored in the memory of the diagnostic device 1 to the server device 4 via the information processing device 2 and the communication network 9. Send.

Large facilities may have thousands to tens of thousands of steam traps installed. In this case, manual diagnosis of each steam trap by the operator using the diagnostic device 1 requires a large amount of time. For this reason, some facilities permanently install a measuring device 3 in each steam trap that can communicate with the server device 4 via the communication network 9.

The measuring device 3 measures the vibration and temperature of each steam trap periodically, for example once a month, and transmits the measured data of the vibration and temperature to the server device 4. In this case, like the diagnostic device 1, the server device 4 diagnoses each steam trap based on the received measurement data.

The server device 4 receives various information such as information indicating the diagnosis results of a plurality of steam traps received from the diagnosis device 1, measurement data received from the measurement device 3, and information indicating the diagnosis results of each steam trap diagnosed based on the measurement data. Manage your information.

Note that any information processing device (not shown) that has access rights to the server device 4 can access the server device 4 via the communication network 9 . This allows the information processing device to view various information managed by the server device 4.

<Configuration of server device 4>
Next, details of the configuration of the server device 4 will be explained. FIG. 2 is a diagram showing an example of the configuration of the server device 4. As shown in FIG. The server device 4 includes a communication section 46, a storage section 45, and a control section 41.

The communication unit 46 is configured using a communication circuit compatible with any communication method such as IP. The communication unit 46 communicates with external devices such as the information processing device 2 via the communication network 9.

The storage unit 45 is configured using any rewritable storage device such as an HDD, SSD, or flash memory. The storage unit 45 stores equipment information 51 of each facility in association with identification information of one or more facilities.

The facility equipment information 51 is information regarding a plurality of steam traps and piping systems managed in the facility. The facility equipment information 51 includes identification information, location information, attribute information, condition information, and characteristic information of each of the plurality of steam traps managed by the facility. Additionally, the equipment information 51 of the facility includes piping characteristic information indicating the characteristics of the piping constituting each piping system managed by the facility, and information indicating the time when the equipment information 51 was stored in the server device 4 (hereinafter referred to as (registration timing information).

The piping characteristic information includes group identification information indicating each piping system, and a function (hereinafter referred to as leakage amount characteristic functions) are included. The leakage characteristic function is predetermined based on experimental values and the like. The leakage amount characteristic function indicates a linear function in which the amount of steam leakage linearly increases over time. The rate of increase in the amount of steam leakage indicated by the leakage amount characteristic function differs depending on the material of the piping constituting each piping system.

For example, in a pipe made of low alloy steel (Cr--Mo steel), a layer of steam oxidized scale made of magnetite and a layer of steam oxidized scale made of spinel oxide accumulate in a flat manner with approximately the same thickness. Piping made of low-alloy steel has the characteristic that although steam oxidation scale accumulates thickly, the steam oxidation scale rarely peels off from the piping.

On the other hand, in piping made of austenitic stainless steel, steam oxidation scale accumulates in complicated shapes due to the influence of the chromium-enriched layer in the piping. For this reason, austenitic stainless steel piping has the characteristic that water vapor oxidation scale is more easily peeled off from the piping than low alloy steel (Cr-Mo steel) piping.

Therefore, the rate of increase in steam leakage (the slope of the leakage characteristic function) of a piping system made of austenitic stainless steel piping is the same as the rate of increase in steam leakage (the slope of the leakage characteristic function) of a piping system made of austenitic stainless steel. The rate of increase in the amount of steam leakage is determined to be larger than the rate of increase in the amount of steam leakage indicated by the leakage amount characteristic function of the piping system.

Next, the flow of processing performed in the steam trap management system 100 when an operator performs diagnostic work on a plurality of steam traps using the diagnostic device 1 will be described. FIG. 4 is a sequence diagram showing the flow of processing during diagnostic work in the steam trap management system 100. The information processing device 2 creates a management ledger 52 regarding a plurality of steam traps to be subjected to diagnostic work in accordance with an operation by an operator (step S1).

The information processing device 2 transmits the management ledger 52 created in step S1 to the server device 4 along with the identification information of the facility where a plurality of steam traps to be subjected to the diagnostic work are installed (step S2).

In the server device 4, the communication unit 46 receives the facility identification information and the management ledger 52 transmitted from the information processing device 2. The management unit 411 acquires the identification information of the facility and the management ledger 52 from the communication unit 46, and stores the management ledger 52 in the storage unit 45 in association with the identification information of the facility (step S3).

The information processing device 2 stores the management ledger 52 created in step S1 in the flash memory in accordance with the operation by the operator. The operator connects the flash memory in which the management ledger 52 is stored to the diagnostic device 1 (step S4).

The additional diagnostic timing information and diagnostic result information of each steam trap and the position information of the steam trap corresponding to the diagnostic timing information and diagnostic result information may be transmitted to the server device 4.

Accordingly, in the server device 4, in step S11, the management unit 411 acquires the timing information, the position information of each steam trap, the diagnosis timing information, and the diagnosis result information received by the communication unit 46 from the communication unit 46. You can do it like this. In line with this, the management unit 411 associates the acquired diagnosis timing information and diagnosis result information with the facility identification information acquired in step S10, and stores the acquired timing information in the storage unit 45. The information may be added to the management ledger 52 that includes the timing information and also includes the same location information as the acquired location information.

In this case, in step S34, the acquisition unit 414 acquires first information indicating the temporal change in the amount of steam leaked from the first steam trap in the most recent first period as result information corresponding to the first report. . Further, in step S34, the acquisition unit 414 calculates, for each of the plurality of second steam traps of the same type as the first steam trap, the amount of steam leakage in a second period that is longer than the first period of each second steam trap. Second information indicating a temporal transition is acquired as result information corresponding to the first report.

Calculate an approximation function that indicates the change in leakage amount over time.

The extraction unit 416 extracts various information regarding the report from the result information corresponding to the report acquired in step S34 (step S36).

For example, in step S36, the extraction unit 416 extracts steam leakage in a third period having the same length as the first period from among the plurality of second information acquired as result information corresponding to the first report in step S34. Similar performance information in which the time course of the amount is similar to the time course of the amount of steam leakage indicated by the first information acquired as the result information corresponding to the first report in step S34 is extracted.
