Japanese Patent Application Publication No. 2014-185968

However, even if a corrosion sensor such as that shown in Patent Document 1 is attached to an electrical product to be inspected and the environment in which the electrical product is installed is measured, if the electrical product breaks down, It is difficult to determine whether the failure is deeply influenced by the environment in which the electrical product is installed, or whether the failure is due to factors common to products of the same type as the electrical product, rather than the installation environment.

This invention was made to solve such problems. The purpose of this is to obtain information that can assist in determining whether the cause of a product's failure is due to the installation environment of the product, or whether it is not the installation environment but is common to products of the same type. The purpose is to obtain a measurement method.

The environmental measurement method according to the present invention includes a collection step of collecting deposits from a collection area set at a part of a product exposed to outside air, and a qualitative analysis and quantitative analysis of the deposits collected in the collection step. an analysis step for performing one or both of the above, and a result accumulation step for storing and accumulating the data of the analysis results of the analysis step in a storage device for each product of the same type, and the collection area is configured to collect data for each product of the same type. The method further includes a step of storing in the storage device a failure history that is predetermined at the same location in the product and includes the installation date, failure occurrence date, and failure details for each product.

According to the environmental measurement method according to the present invention, it is possible to support the determination of whether the cause of a product failure is due to the installation environment of the product, or whether it is not the installation environment but is common to products of the same type as the product. This has the effect of allowing information to be obtained.

The environment measurement system according to Embodiment 1 of the present invention measures the installation environment of electrical products. As shown in FIG. 1, a collection area 100 is set in a product 1 whose installation environment is to be measured by the environmental measurement system. The collection area 100 is set at a location in the product 1 that is exposed to the outside air. The collection area 100 is predetermined at the same location in the product 1 for the same type of product 1.

Next, a specific example of the collection area 100 set for each type of product 1 will be described with reference to FIGS. 2 to 8. First, FIG. 2 shows an example in which the product 1 is a lighting device 10. The lighting device 10 is specifically, for example, an LED floodlight. The lighting device 10 includes a light source section 11 and a power supply section 12. The light source section 11 is provided with a light source (not shown), in this example an LED (light emitting diode), a reflector, and the like. The power supply section 12 includes a power supply circuit (not shown) for supplying power to the light source section 11 .

The power supply section 12 is housed inside the power supply cover 13. The power supply cover 13 has, for example, a rectangular parallelepiped box shape with an open bottom side. The bottom side of the power supply cover 13 is fixed to the top surface of the light source section 11 with the packing 14 in between. A ventilation filter 15 is attached to the power supply cover 13. A cable gland 16 is also attached to the power supply cover 13. The power cable is fixed to the power supply cover 13 by the cable gland 16. Further, the cable gland 16 prevents foreign matter from entering the power supply cover 13 from the power cable inlet.

The collection area 100 is arranged on the side surface of the power supply cover 13. As described above, the light source section 11 is located under the power supply cover 13. Therefore, when the illumination device 10 is hung and installed at a high place, the collection area 100 is hidden behind the light source section 11 and is difficult to see. Therefore, the collection area 100 can be exposed to the outside air while being made less conspicuous. Further, it is possible to prevent the collection area 100 from being touched inadvertently.

Furthermore, the packing 14, ventilation filter 15, and cable gland 16 are components that are easily attacked by corrosive gas components in the installation environment. By placing the sampling area 100 near parts that are easily attacked by these corrosive gas components, if an abnormality occurs in these parts, it is possible to determine whether or not the corrosive gas component is the cause of the abnormality. This makes it easier to make decisions. Moreover, if it is a side surface of the power supply cover 13, the functions of the power supply cover 13, such as heat dissipation, will not be affected.

Next, FIGS. 3 to 5 show examples in which the product 1 is an outdoor unit 20 of an air conditioner. As shown in FIG. 3, the outdoor unit 20 includes an outdoor unit housing 21, an outdoor unit fan 23, and a fan guard 24. A service panel 22 is removably attached to the side surface of the outdoor unit housing 21. The outdoor unit fan 23 is housed inside the outdoor unit casing 21 at an upper end portion. A fan guard 24 is removably attached to the upper side of the upper surface of the outdoor unit housing 21. The fan guard 24 covers the outdoor unit fan 23 from above. As shown in FIGS. 3 and 4, the fan guard 24 has ventilation holes 25 formed therein. Therefore, the inside and outside of the fan guard 24 communicate through the ventilation holes 25.

As shown in FIG. 5, the collection area 100 is arranged on the inner surface of the fan guard 24. As described above, the inside and outside of the fan guard 24 communicate through the ventilation holes 25. Therefore, the inner surface of the fan guard 24 is exposed to the outside air. For this reason, the collection area 100 can be exposed to the outside air while being made less conspicuous. Further, it is possible to prevent the collection area 100 from being touched inadvertently. Further, since the outdoor unit 20 is installed outdoors, by arranging the collection area 100 on the inner surface of the fan guard 24, the collection of deposits can be made less susceptible to the influence of wind and rain.

Next, FIG. 6 shows an example in which the product 1 is a ventilation device 30. Specifically, the ventilation device 30 is, for example, a ceiling cassette type ventilation device installed on the ceiling. The ventilation device 30 includes a ventilation device housing 31. The ventilation device housing 31 has, for example, a rectangular parallelepiped shape. A ventilation opening 32 is formed on the lower surface of the ventilation device housing 31, that is, the surface exposed to the ceiling during installation. An air supply pipe connection portion 33 is provided on one end surface of the ventilation device housing 31. An exhaust pipe connection portion 34 is provided on the other end surface of the ventilation device housing 31.

The collection area 100 is arranged on the side surface of the ventilation device housing 31. The ventilation device housing 31 is arranged under the ceiling except for the lower surface where the ventilation opening 32 is formed. In other words, the side surface of the ventilation device housing 31 is placed behind the ceiling. Therefore, the collection area 100 can be exposed to the outside air while being made less conspicuous. Further, it is possible to prevent the collection area 100 from being touched inadvertently.

Finally, FIGS. 7 and 8 show an example in which the product 1 is a control panel 40. The control panel 40 includes a box body 41 and a lid body 42. The box body 41 has, for example, a rectangular parallelepiped box shape with an open front side. As shown in FIG. 8, various types of equipment 43 are housed inside the box 41. As shown in FIG. Wiring 44 is connected to the equipment 43 housed in the box 41 . Wiring 44 leads to the outside of control panel 40 . An opening 45 is formed in, for example, the upper surface of the box 41 . The opening 45 is an opening for pulling out the wiring 44 from the inside of the box 41 to the outside, or for pulling the wiring 44 into the inside of the box 41 from the outside. Therefore, the wiring 44 is passed inside the opening 45. The lid 42 is attached to the box 41 so that the front surface of the box 41 can be opened and closed.

As shown in FIG. 8, the collection area 100 is arranged on the inner surface of the lid 42. Since the opening 45 is formed in the box 41, the inside of the box 41 communicates with the outside through the opening 45 even when the lid 42 is closed. Therefore, even when the lid 42 is closed, the inner surface of the lid 42 is exposed to the outside. In other words, the collection area 100 can be exposed to the outside air while still being hidden from the public eye. Further, it is possible to prevent the collection area 100 from being touched inadvertently.

Note that the location of the collection area 100 for the product 1 may be determined visually. In order to be able to determine the position of the collection area 100 from its appearance, for example, the boundary line of the collection area 100 may be printed or engraved. Furthermore, instead of the boundary line, for example, only the four corners of the collection area 100 may be shown, the position of the collection area 100 may be indicated with an arrow, or characters that make it clear that it is the collection area 100 may be displayed. Furthermore, the color of the collection area 100 may be made different from the surrounding area, or the collection area 100 may be recessed or protruded from the surrounding area.

However, it is also possible to make it impossible to distinguish between the collection area 100 and other areas from the outside. In this case, for example, the location of the collection area 100 may be written in the work manual or the like. By doing so, the collection worker can collect the deposits from the collection area 100 by checking the work manual and the like.

Additionally, the collection area 100 may include a porous coating. By doing so, the porous coating film can better capture splashes of sea salt, oil smoke, etc., and corrosive gas components in the environment in which the product 1 is installed. Further, by using a porous coating film covering the surface of the product 1, it is possible to suppress the product 1 from being attacked by corrosive gas components captured in the collection area 100. Specifically, for example, silicone rubber, epoxy resin, urethane resin, acrylic resin, etc. can be used as the porous coating film. By using these resins or rubbers, the porous coating film can be prevented from peeling off due to attack by corrosive gases, etc., and can also be used to trap corrosive gases, etc. traces can be obtained. In particular, silicone rubber is suitable because it can be easily peeled off from the installation location during paint film recovery work for collecting deposits.

The environmental measurement system according to this embodiment includes an analysis device 2 and a storage device 3, as shown in FIG. The analyzer 2 is a device that analyzes deposits collected from the collection area 100 set on the product 1 as described above. When collecting deposits from the collection area 100, the inside of the collection area 100 is wiped a predetermined number of times with, for example, a clean cloth. Furthermore, if the collection area 100 is provided with the porous coating film described above, the product 1 may be collected by peeling off the porous coating film.

The analyzer 2 performs one or both of a qualitative analysis and a quantitative analysis on the collected deposits. For qualitative analysis and quantitative analysis at this time, well-known analysis methods can be used. In the analysis, first, pretreatment is performed such as extracting deposits from the cloth or porous coating film used for collection using a wet method. Then, qualitative analysis and quantitative analysis are performed using, for example, ion chromatography analysis, gas chromatography analysis, fluorescent X-ray analysis, and the like.

The storage device 3 stores and accumulates data of the analysis results of the analysis device 2. At this time, the storage device 3 stores the data of the analysis results for each product 1 of the same type.

The environment measurement method carried out in the environment measurement system configured as described above is as shown in the flow diagram of FIG. That is, first, in step S1, a sampling step is performed. The collection process is a process of collecting deposits from a collection area 100 set at a part of the product 1 that is exposed to the outside air. At this time, the collection area 100 is predetermined at the same location in the product 1 for the same type of product 1. After step S1, the process proceeds to step S2.

In step S2, an analysis step is performed. The analysis step is a step in which the analyzer 2 performs one or both of qualitative and quantitative analysis of the deposits collected in step S1. After step S2, the process proceeds to step S3.

In step S3, a result accumulation step is performed. The result accumulation step is a step of storing and accumulating data of the analysis results in step S2 in the storage device 3 for each product of the same type. When the process in step S3 is completed, the series of processes ends.

As described above, the environmental measurement method according to this embodiment includes a collection step, an analysis step, and a result accumulation step. The collection process is a process of collecting deposits from a collection area 100 set at a part of the product 1 that is exposed to the outside air. At this time, the collection area 100 is predetermined at the same location in the product 1 for the same type of product 1. The analysis step is a step in which the analyzer 2 performs one or both of a qualitative analysis and a quantitative analysis of the deposits collected in the collection step. The result accumulation step is a step of storing and accumulating data of the analysis results of the analysis step in the storage device 3 for each product of the same type.

According to the environment measurement system and environment measurement method configured as described above, qualitative and quantitative analysis data of sea salt, corrosive gas, oil smoke, etc. present in the installation environment of the product 1 is stored in the storage device 3. is accumulated. At this time, the analysis data is summarized for each product 1 of the same type, and for the products 1 of the same type, the samples on which the analysis is based are collected at the same location in the product 1. Therefore, the storage device 3 accumulates environmental measurement data with the same conditions other than the installation environment. Therefore, by referring to the data stored in the storage device 3 when a failure occurs in the product 1, it is possible to support an appropriate evaluation of the influence of the installation environment on the same type of product 1, and to prevent the failure of the product 1. It is possible to support the determination of whether the cause is due to the installation environment of the product 1 or whether it is not the installation environment but is common to products 1 of the same type as the product 1.

Note that, in addition to the analysis result data, the storage device 3 may also store the installation date and failure history of each product 1. The failure history includes information such as the date of failure occurrence and the details of the failure. By doing so, it is possible to provide information that makes it easier to determine the relationship between the installation environment and the failure.
