Description

The present invention relates to an inspection system used for inspection of equipment to be inspected installed in a plant, an operation method of the inspection terminal, and a control program for controlling the inspection terminal.

2. Description of the Related Art In the premises of plants such as petrochemical plants and thermal power plants, pipes are laid for circulating various fluids used in the operation of the plants. If the piping is damaged, the fluid cannot flow, which not only hinders the operation of the plant, but also causes damage to employees and the surrounding environment due to leakage of the fluid. In order to prevent such a situation, regular or irregular diagnosis is performed on the piping laid in the plant.

In general, a wide variety of fluids are used for plant operation, and these fluids must be used at various locations within the plant, so a large number of pipes are laid over a considerable extended distance within the plant. In this way, since the number and extension distance of piping are large, the diagnosis history of piping can also be a considerable amount of information. Therefore, it can be said that how to manage such diagnostic history information efficiently and in an organized state is an important issue in plant management.

For example, Japanese Patent Application Laid-Open No. 2017-4279 (Patent Document 1) discloses an information collection system that can be used for plant management, and the system includes an information collection terminal device and an information collection server device that collects input information transmitted from the information collection terminal. According to the system of Patent Literature 1, a worker carrying an information collection terminal device goes to a site where various devices and facilities are installed, and input information is accumulated in the information collection server device by inputting inspection results into the information collection terminal device.

When operating a system such as that disclosed in Patent Document 1, since multiple terminal devices operate simultaneously, information is uploaded from multiple terminal devices to the data server, and information related to test results for the same test object may conflict.

Embodiments of an inspection terminal, an operation method, and a control program according to the present invention will be described with reference to the drawings. An inspection system 1 for inspecting a group of pipes 2 (FIG. 2) laid on the premises of a plant P such as a petrochemical plant or a thermal power plant will be described below as an example. Inspection system 1 is an embodiment of an inspection system according to the present invention.

[Equipment configuration and system configuration]
First, an inspection system 1 according to this embodiment and a group of pipes 2 to be diagnosed will be described. As shown in FIG. 1, an inspection system 1 according to this embodiment includes an inspection terminal 3 and a data server 4 that are configured to communicate with each other. Here, the inspection terminal 3 is an embodiment of the inspection terminal according to the present invention. The inspector inspects various parts of the pipe group 2 consisting of a large number of pipes 21 (which are examples of equipment to be inspected) laid within the site of the plant P, and inputs the inspection results into the inspection terminal 3 . Defect information input to the inspection terminal 3 is transmitted to the data server 4 and stored therein.

As shown in FIG. 2 , the pipe 21 is laid while being supported by a plurality of racks 22 that are spaced apart along the longitudinal direction of the pipe 21 . The rack 22 has a width larger than the diameter of the pipes 21 in the horizontal direction, and can accommodate a plurality of pipes 21 arranged in the horizontal direction. Moreover, the rack 22 has a plurality of layers in the vertical direction, and each of the plurality of layers can receive a plurality of pipes 21 . That is, in order to effectively use the site, the pipes 21 are laid in a concentrated manner in the horizontal direction and the vertical direction.

A specific portion of each pipe 21 in the plant P is identified by a pipe name 21a assigned to each pipe 21, a rack number 22a assigned to each rack 22, and a hierarchy number 22b assigned to each hierarchy of each rack 22. For example, the location denoted by Ex1 in FIG. 2 is specified by each information of "No. 51 pipe", "Right above No. 34 rack", and "Layer 2F". Similarly, the location marked Ex2 in FIG. 2 is specified by each information of "Pipe No. 61", "Between Rack No. 34 and Rack No. 35", and "Layer 1F".

As shown in FIG. 1 , the inspection system 1 includes an inspection terminal 3 and a data server 4 . The inspection terminal 3 has a touch panel 31 (an example of an input device and an example of a display device), a communication device 32 , a position specifying device 33 , a storage device 34 and an arithmetic device 35 . The data server 4 has a communication device 41 , a storage device 42 and an arithmetic device 43 .

(Configuration of inspection terminal)
The touch panel 31 is implemented as a known touch panel in this field. The touch panel 31 is a device capable of receiving an input operation from a user and displaying information to the user.

The communication device 32 includes a mobile phone module 321 , a wireless LAN module 322 and a short-range wireless communication module 323 . The communication device 32 can communicate with the data server 4 and also communicate with the other inspection terminals 3A, as described below.

A mobile phone module 321 is a known module connectable to a mobile phone line. From the viewpoint of communication speed, it is preferable that the mobile phone module 321 be a module connectable to a mobile phone line configured as a radio communication system after the fourth generation mobile communication system.

The wireless LAN module 322 is a known module connectable to a wireless LAN network. From the viewpoint of communication speed, it is preferable that the module conforms to a standard that enables relatively high-speed communication, such as IEEE802.11ax, IEEE802.11ac, and IEEE802.11n.

The mobile phone module 321 and wireless LAN module 322 are responsible for communication between the inspection terminal 3 (communication device 32) and the data server 4 (communication device 41). That is, the inspection terminal 3 connects to the network N via the mobile phone module 321 or the wireless LAN module 322 and communicates with the data server 4 via the network N. FIG. Here, the network N can be the Internet, an intranet, or the like.

The short-range wireless communication module 323 is a known module capable of communicating with modules of the same type located relatively nearby, and can be, for example, a module compatible with the Bluetooth (registered trademark) standard. More specifically, the short-range wireless communication module 323 may be a module that communicates with an output of 100 mW or less. The short-range wireless communication module 323 with this configuration has a communication range with a radius of about 100 m. For example, in the case of the Bluetooth (registered trademark) standard, a module that communicates with an output of 100 mW or less is defined as a module that conforms to Bluetooth (registered trademark) class 1.

The short-range wireless communication module 323 is responsible for mutual communication between the inspection terminals 3 . That is, the two inspection terminals 3 can communicate with each other via the short-range wireless communication modules 323 of each other.

The position specifying device 33 is a device capable of specifying the current position of the inspection terminal 3 . More specifically, the position specifying device 33 is implemented as a global positioning satellite system (GNSS) module typified by a GPS module.

The storage device 34 stores map data relating to the plant P and inspection data associated with any one of the plurality of pipes 21 . The storage device 34 also stores a control program for the inspection terminal 3 . Storage device 34 may be implemented as a known storage device such as a hard disk drive or solid state drive.

The arithmetic device 35 is a device that executes various arithmetic processing executed in the inspection terminal 3, and can be implemented as a known arithmetic device such as a CPU.

(Data server configuration)
The communication device 41 is implemented as a LAN module. In view of the fact that the data server 4 is usually installed as a stationary type, the LAN module may be wired or wireless. The data server 4 is connected to the network N via the communication device 41 and communicates with the inspection terminal 3 via the network N. FIG.

The storage device 42 stores inspection data received from the inspection terminal 3 and a user database including information on a plurality of users using the inspection terminal 3 . The storage device 42 also stores a control program for the data server 4 (an example of the control program according to the present embodiment). The storage device 42 can be implemented as a known storage device such as a hard disk drive or solid state drive.

The arithmetic device 43 is a device that executes various arithmetic processing executed in the data server 4, and can be implemented as a known arithmetic device such as a CPU.

[Structure of inspection data]
The inspection data is data indicating the result of inspection of the pipe group 2 (pipe 21). Inspection data is associated with any one of the plurality of pipes 21 . More specifically, the inspection data includes, as attribute values, a data ID, a pipe attribute value (an example of an equipment attribute value), a fluid attribute value, a date and time attribute value, a user attribute value, an importance attribute value, a synchronization attribute value, an inspection result attribute value, and a lock attribute value.

The pipe attribute value is information representing a portion of the pipe 21 to which inspection data is to be associated (hereinafter referred to as "inspection point"), and plays a role of specifying the inspection target point. The inspection data includes, as pipe attribute values, text data representing pipe name 21a, rack number 22a, and layer number 22b, for example. Further, the pipe attribute value may include information (such as longitude and latitude) specifying the position of the location to be inspected instead of or in addition to the information such as the pipe name 21a. Furthermore, the pipe attribute value may further include information representing the function of the pipe 21 at the inspection location. For example, the pipe attribute value may include information representing the division (main pipe, branch pipe, etc.) of the pipe 21 at the inspection location.

The fluid attribute value is information representing the fluid flowing through the inspection location. The inspection data includes, as fluid attribute values, text data representing the name of the fluid flowing through the pipe 21, numerical data representing the pressure and flow rate of the fluid, and the like.

The date and time attribute value is information representing the date and time when the examination location was inspected. For example, as the date/time attribute value, the date/time at the moment when the inspection data was edited is automatically obtained.

The user attribute value is information representing the user who entered the examination data. The inspection data includes, as a user attribute value, for example, text data representing the ID of the user who entered the inspection data. A user of the inspection terminal 3 inputs inspection data while logging into the inspection terminal 3 using a set of an ID and a password that are individually assigned. As the user attribute value, the ID of the user who logged in when the inspection data was input is automatically used.

The importance attribute value is information representing the importance of the inspection location. The inspection data includes, as importance attribute values, numerical data representing one of several predetermined importance levels, for example. The importance attribute value may be freely set by the user of the inspection terminal 3, or may be automatically determined based on the piping attribute value, the fluid attribute value, or the like.

The synchronization attribute value is information indicating whether or not the inspection data is to be synchronized with the data server 4 . Inspection data with a synchronization attribute value of “1” is uploaded to the data server 4 , and inspection data with a synchronization attribute value of “0” is not uploaded to the data server 4 . For example, when re-inspecting a location that has been inspected in the past, inspection data associated with the location is downloaded from the data server 4 to the inspection terminal 3, and the result of the re-inspection is input by updating the downloaded inspection data. The inspection data in this case has a synchronous attribute value of "1", and after the result of the second inspection is input, the updated inspection data is uploaded to the data server 4, and the inspection data stored in the data server 4 (storage device 42) is updated.

On the other hand, the user of the inspection terminal 3 can arbitrarily select a synchronous attribute value for inspection data of a location newly inspected by the user. At this time, the inspection data whose synchronization attribute value is set to "0" is stored only in the inspection terminal 3 (storage device 34) that created the inspection data.

The inspection result attribute value is information representing the inspection result for the inspection location. The inspection data includes, for example, text data representing the inspection result for the inspection location as an inspection result attribute value, so that the presence/absence, type, degree, and the like of defects can be specified. The inspection result attribute value may be set so that the user can input arbitrary text, or the user can select from preset candidates.

The lock attribute value is information indicating whether or not editing of inspection data is restricted depending on whether or not communication with the data server 4 is possible. In principle, inspection data whose lock attribute value is "1" can be edited only when communication with the data server 4 is possible. On the other hand, inspection data whose lock attribute value is “0” can be edited regardless of whether or not communication with the data server 4 is possible in principle.

Lock attribute values can be set in conjunction with other attribute values. For example, inspection data whose synchronization attribute value is "1" is inspection data that needs to be synchronized with the data server 4, so if editing is performed in a state in which communication with the data server 4 is disabled, there is a possibility that inspection data conflicts later. Therefore, the lock attribute value is set to "1" for the inspection data whose synchronization attribute value is "1". Further, for example, examination data whose importance attribute value exceeds a predetermined threshold value should not be edited in a state in which communication with the data server 4 is disabled, because management accuracy needs to be improved. Therefore, the lock attribute value is set to "1" for inspection data whose importance attribute value exceeds a predetermined threshold. Inspection data whose lock attribute value is set to "1" is hereinafter referred to as lock target inspection data.

Note that the inspection data may include other attribute values as described above. Other attribute values include, for example, a treatment attribute value indicating treatment information for a defect at an inspected location, an image attribute value including image data of an inspected location, and the like.

[Configuration of Control Program for Inspection Terminal]
In the present embodiment, the inspection terminal 3 side executes an inspection data editing function, a communication determination function, a layout drawing display function, and a lock control function. Each of these functions is realized by a control program executed by the arithmetic unit 35 of the inspection terminal 3. FIG. In addition to the functions described below, a function of exchanging inspection data with the data server 4 is also executed.

(1) Inspection Data Editing Function The inspection data editing function is a function of editing inspection data according to an input operation input by the user via the touch panel 31 . When executing the inspection data editing function, each attribute value included in the inspection data to be edited is displayed on the touch panel 31 . In the present embodiment, an edit window 6 is displayed superimposed on the layout drawing screen 5 (FIG. 3), and by performing an operation on the edit window 6, inspection data can be edited. At this time, attribute values that can be arbitrarily edited by the user (for example, piping attribute values) and attribute values that cannot be arbitrarily edited (for example, date and time attribute values) are displayed in different manners.

(2) Communication Determining Function The communication determining function is a function for determining whether communication with the data server 4 via the communication device 32 (mobile phone module 321 and wireless LAN module 322) is possible, and whether communication with another inspection terminal 3A via the communication device 32 (near-field wireless communication module 323) is possible. The communication determination function may run in the background.

Whether or not communication with the data server 4 is possible is determined, for example, by actually trying to communicate with the data server 4 periodically. As an alternative configuration, whether or not communication with the data server 4 is possible may be determined based on the strength of radio waves received by the mobile phone module 321 and the wireless LAN module 322 .

Whether or not communication with other inspection terminals 3A is possible is determined, for example, by periodically attempting communication with the same type of short-range wireless communication module 323 . If the short-range wireless communication module 323 is a module compatible with the Bluetooth (registered trademark) standard, whether or not communication is possible can be determined through transmission and reception of advertising packets. Being able to communicate with another inspection terminal 3A means that the other inspection terminal 3A exists within the communication range of the short-range wireless communication module 323 (for example, within a radius of about 100 m), that is, in the vicinity of the inspection terminal 3.

(3) Layout map display function The layout map display function is a function for displaying the layout map screen 5 ( FIG. 3 ) on the touch panel 31 . A map 51 of the plant P is displayed on the touch panel 31 based on the layout drawing screen 5, the map data and the inspection data stored in the storage device 34, and objects 52 representing each of a plurality of inspection points are displayed on the map 51. Each object 52 is associated with inspection data, and the position of each object 52 on the map 51 is determined according to the pipe attribute value of the inspection data. That is, an object 52 created based on the inspection data is displayed at a position on the map 51 representing the actual position of the pipe 21 with which the inspection data should be associated.

On the layout drawing screen 5, a drawing number 53, a plant map 54, and a rack drawing 55 for specifying the position in the plant P of the map 51 displayed on the layout drawing screen 5 are displayed.

When one of the objects 52 is touched while the layout drawing screen 5 is displayed on the touch panel 31, an editing window 6 for inspection data associated with the object 52 is displayed, and a transition is made to an inspection data editing function. This allows the user of the inspection terminal 3 to intuitively select inspection data to be edited.

When the communication determination function determines that communication with the data server 4 is not possible, the layout display function displays the object 52A associated with the lock target inspection data and the other objects 52B in different modes. In other words, the display mode of each object 52 is determined with reference to the lock attribute value of the inspection data. Specifically, the object 52A associated with the lock target inspection data is displayed in a relatively light color (eg, gray), and the object 52B associated with other inspection data is displayed in a relatively dark color (eg, black). Even if the object 52A displayed in light color is touched, the transition to the inspection data editing function is not performed. On the other hand, when an object 52B displayed in a dark color is touched, a transition is made to an inspection data editing function for inspection data associated with the touched object.

On the other hand, when the communication determination function determines that communication with the data server 4 is possible, all the objects 52 are displayed in the same manner. In this case, even if any object 52 is touched, the transition to the inspection data editing function for the inspection data associated with the touched object 52 is performed.

In addition, the distinction of the display mode of the object 52 is not limited to the distinction by color as illustrated above. For example, the objects 52 may be distinguished according to their shape, movement (for example, lighting and blinking), size, and the like. Also, the object 52A associated with the lock target inspection data may not be displayed. In this case as well, if the object 52A is considered to be displayed as a colorless object, it can be said that it is displayed in a manner different from that of the object 52B.

(4) Lock Control Function The lock control function is a function for temporarily changing whether inspection data that satisfies predetermined requirements is designated as lock target inspection data (that is, lock attribute value).

A first function of the lock control function is a function of temporarily canceling the designation of lock-target inspection data that satisfies predetermined requirements as lock-target inspection data. Specifically, the lock attribute value of the lock target inspection data that satisfies a predetermined requirement is temporarily changed to "0". The predetermined requirements are two things: that the inspection terminal 3 is located in the vicinity of the inspection location associated with the lock target inspection data, and that there is no other inspection terminal 3A in the vicinity of the inspection terminal 3.

Whether or not the first requirement is satisfied is determined based on the current position of the inspection terminal 3 specified by the position specifying device 33 . If the deviation between the current position of the inspection terminal 3 and the position of the inspection location specified by the pipe attribute value of the lock target inspection data is equal to or less than a predetermined threshold, it is determined that the first requirement is satisfied.

Whether or not the second requirement is satisfied is determined based on the determination result of whether or not communication with the other inspection terminal 3A is possible in the communication determination function. In the communication determination function, it is determined that the second requirement is satisfied when it is determined that communication with the other inspection terminal 3A is impossible.

Satisfaction of the first requirement means that the inspection terminal 3 is located near the inspection point associated with the lock target inspection data. Satisfaction of the second requirement means that there is no other inspection terminal 3A in the vicinity. Considering these together, satisfying both of the two requirements means that the inspection terminal 3 is located near the inspection point associated with the lock target inspection data, and that there is no other inspection terminal 3A in the vicinity of the inspection point. In this situation, there is little possibility that competition will occur with respect to the inspection data of the inspection location, so even if the designation as the inspection data to be locked is temporarily canceled, there is little possibility of causing a problem.

A second function of the lock control function is to temporarily designate inspection data that satisfies predetermined requirements as lock target inspection data. Specifically, the lock attribute value of the lock target inspection data that satisfies a predetermined requirement is temporarily changed to "1". The predetermined requirements are two things: that the inspection terminal 3 is located in the vicinity of the inspection location associated with the lock target inspection data, and that another inspection terminal 3A exists in the vicinity of the inspection terminal 3. Here, the first requirement is the same as the first requirement of the first function. Also, the second requirement is the opposite requirement of the second requirement of the second function.

Satisfaction of the first requirement means that the inspection terminal 3 is located near the inspection point associated with the lock target inspection data. Satisfaction of the second requirement means that another inspection terminal 3A exists in the vicinity. Considering these together, satisfying both of the two requirements means that the inspection terminal 3 is located near the inspection point associated with the lock target inspection data, and that another inspection terminal 3A exists in the vicinity of the inspection point. In this case, since it is presumed that a plurality of users are trying to perform the inspection of the same inspection point, it can be said that there is a high possibility that competition of inspection data will occur. Therefore, the inspection data is temporarily designated as the inspection data to be locked to avoid the conflict.

When either the first function or the second function works, the operation of the layout drawing display function follows the temporarily changed lock attribute value. That is, when the designation of the inspection data to be locked is temporarily canceled in the lock control function, the object associated with the inspection data to be locked is displayed in a dark color even in a state in which communication with the data server 4 is disabled. Then, when an object associated with the lock target inspection data is touched, a transition to an inspection data editing function for the inspection data associated with the touched object is performed.

Further, when the inspection data is temporarily designated as the inspection data to be locked in the lock control function, the object associated with the inspection data is displayed in a light color even if the communication with the data server 4 is possible. Even if the object associated with the inspection data is touched, the transition to the inspection data editing function is not performed.

For both the first function and the second function, the temporarily changed lock attribute value is returned to the original value when the two requirements specified in each are no longer satisfied.

[Data server control program configuration]
In this embodiment, the data server 4 side executes a query function, an update function, a determination function, and a conflict processing function. Each of these functions is realized by a control program executed by the arithmetic unit 43 of the data server 4. FIG. In addition to the functions described below, a function of exchanging inspection data with the inspection terminal 3 is also executed, but since it is a well-known function of exchanging data between the data server and the terminal device, a description thereof will be omitted.

(1) Inquiry function The inquiry function is a function of inquiring the user attribute value of the newly input inspection data against the user database stored in the storage device 42, and acquiring information related to the user specified by the user attribute value from the user database. Here, “newly input inspection data” refers to inspection data newly input to the inspection terminal 3 or newly edited at the inspection terminal 3 and then uploaded to the data server 4 . In each record of the user database, information such as the user's name, skill level, qualification, years of experience, number of inspections, etc. specified by the user attribute value is stored as attributes using the user attribute value as a key. Therefore, by executing the inquiry function, it is possible to specify the name, skill level, qualification, years of experience, number of inspections, etc. of the user who performed the inspection related to the newly input inspection data.

(2) Update Function The update function is a function of updating the past inspection data related to the inspection location associated with the newly input inspection data with the newly input inspection data. Whether or not newly input inspection data is inspection data that can update past inspection data is determined based on the pipe attribute value and the date and time attribute value. That is, inspection data containing certain pipe attribute values can be updated with new inspection data containing the same pipe attribute values. Also, whether a plurality of inspection data are new or old is determined based on the date and time attribute value.

(3) Judgment Function The judgment function is a function for judging whether or not to execute the update function based on information related to the user who has input newly input inspection data. The information related to the user used for determination here is specified by executing the inquiry function for the newly input test data. Four functions that can be executed in the determination function are described below, but not all functions need to be executed.

As a first determination function, a determination can be made in consideration of the pipe attribute value. For example, if the classification (main pipe, branch pipe, etc.) of the pipe 21 that has the authority to update the inspection data is set in advance according to the skill level of the user, it is possible to determine whether or not to execute the update process based on the combination of the skill level of the user who entered the newly input inspection data and the classification of the pipe 21 specified by the pipe attribute value of the inspection data. For example, if a user whose proficiency level is below a predetermined level is granted the authority to update inspection data only for branch pipes, but not for main pipes, the inspection data relating to the main pipe entered by the user will not be used to update the inspection data of the main pipe in data server 4.

As another aspect of the first function, when the hierarchy (hierarchy number 22b) of the pipe 21 that has the authority to update the inspection data is set in advance according to the qualification of the user, it is possible to determine whether or not to execute the update process based on the combination of the qualification of the user who has newly input the inspection data and the hierarchy number 22b specified by the pipe attribute value of the inspection data. This is an operation in which only users who are qualified to work at height are permitted to update the inspection data of the pipes 21 at a height higher than a predetermined level.

As a second function of the determination function, determination can be made in consideration of fluid attribute values. For example, if the properties (fluid type, pressure, flow rate, etc.) of the fluid in the pipe 21 that has the authority to update the inspection data are set in advance according to the skill level and qualification of the user, it is possible to determine whether or not to execute the update process based on the combination of the information of the user who entered the newly input inspection data and the fluid in the pipe 21 specified by the fluid attribute value of the inspection data. For example, for a pipe 21 that satisfies requirements such as a relatively low-risk fluid such as water or air and a relatively low pressure and flow rate, even a user with a relatively low skill level is allowed to update inspection data. On the other hand, for a pipe 21 that satisfies requirements such as a relatively high-risk fluid such as hydrogen and a relatively high pressure or flow rate, only users with a relatively high skill level are allowed to update the inspection data.

As a third function of the judging function, a judgment can be made in consideration of the importance attribute value. For example, if the degree of importance of the pipes 21 authorized to update the inspection data is set in advance according to the skill level and qualification of the user, it is possible to determine whether or not to execute the update process based on the combination of the information of the user who has entered the newly input inspection data and the importance of the pipes 21 specified by the importance attribute value of the inspection data. Also in this function, it is possible to restrict the skill level of the user who is allowed to update the inspection data according to the degree of importance.

As a fourth function of the decision function, a decision can be made based solely on information about the user. For example, if a user whose number of inspections is less than a predetermined threshold performs inspections as OJT, inputs inspection data to the inspection terminal 3, and uploads the inspection data to the data server 4, but does not use the inspection data to update the inspection data of the data server 4, it may be determined whether or not to execute the update process based on the number of inspections of the user who has input the newly input inspection data.

The judging function is based on the technical concept of judging whether or not to execute the update function, taking into consideration information that can represent the skill level of the user and, if necessary, the characteristics of the inspected part, in any of the functions exemplified above. This prevents inappropriate updating of inspection data by users who do not have the necessary skills.

(4) Conflict Processing Function The conflict processing function is a function for selecting test data to be used for updating the test data in the data server 4 when a plurality of test data conflict. Here, conflict between a plurality of pieces of inspection data means, for example, that the difference in date and time specified by the date and time attribute values of each of the plurality of pieces of inspection data is within a predetermined threshold (hereinafter referred to as conflict threshold). It should be noted that the conflict processing function is based on the premise that each of the plurality of conflicting inspection data is inspection data that is determined to execute the update function in the determination function in a situation where conflict does not occur. Also, a query function is performed for each of the plurality of inspection data.

The conflict handling function selects which of the plurality of test data to use for the update function based on information about each user associated with each of the plurality of test data. Here, the information related to the user is information that can determine the superiority or inferiority of the skill level of the user who entered each inspection data based on the information, for example, the user's skill level, qualification, years of experience, number of inspections, etc. That is, when a plurality of pieces of inspection data compete, the inspection data entered by a user who satisfies conditions such as having the highest level of skill and the highest degree of qualification is assumed to be the most reliable inspection data, and is used for the update function. As a result, inspection data with higher reliability can be accumulated in the data server 4 .

Also, as another aspect of the conflict handling function, the importance attribute value may be further considered. For example, for test data whose importance attribute value is equal to or less than a predetermined threshold, the conflict threshold is set to a relatively small value to make it difficult to determine that they are competing. With this configuration, it is possible to limit the occurrence of competitive processing to inspection locations with high importance, thereby reducing the amount of computational processing and improving the reliability of inspection.

[Other embodiments]
Finally, other embodiments of the inspection terminal, the operating method, and the control program according to the present invention will be described. It should be noted that the configurations disclosed in the respective embodiments below can also be applied in combination with configurations disclosed in other embodiments unless there is a contradiction.

In the above-described embodiment, the configuration in which the inspection terminal 3 has the touch panel 31 that is both an input device and a display device has been described as an example. However, in the inspection terminal according to the present invention, the input device and the display device may be provided separately. Known input devices such as buttons, levers, keyboards, and microphones can be used as such input devices. Moreover, a liquid crystal display etc. are illustrated as such a display apparatus.

In the above embodiment, the configuration in which the query function, the update function, and the determination function are executed by the arithmetic unit 43 of the data server 4 has been described as an example. However, in the present invention, some or all of these functions may be performed by the arithmetic unit of the inspection terminal. For example, based on the ID of the user who logs in to the inspection terminal, the inspection terminal may execute the determination function.

Regarding other configurations, it should be understood that the embodiments disclosed in this specification are examples in all respects, and that the scope of the present invention is not limited by them. Those skilled in the art will easily understand that modifications can be made as appropriate without departing from the scope of the present invention.
