[Technical field]

[0001] The present invention relates to an inspection system, an inspection device, a terminal device, and a method for executing a function change. [Background technology]

[0002] There is an inspection device that performs a gas leak inspection by applying a suction nozzle that sucks in gas to an object to be inspected. Such an inspection is performed using sensitivity and reference values ​​set in the inspection device. Such sensitivity and reference values ​​may be determined in advance depending on the inspection quality. Therefore, when inspecting an object to be inspected, the sensitivity and reference values ​​are preset to be the determined values. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2004-527743 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the sensitivity and reference values ​​that were set according to the test quality are changed after they were set, the test results may be affected. Therefore, if the inspector arbitrarily changes these settings, unintended test results may be obtained, which may affect the test quality.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to provide an inspection system, an inspection device, a terminal device, and a method for executing function changes that can prevent any effect on inspection quality even when operational input is performed. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, one aspect of the present invention is an inspection system capable of communication between an inspection device that inspects an object to be inspected and a terminal device, wherein the terminal device has a first input unit that accepts input of instructions for the inspection device and a transmitting unit that transmits the instructions input from the first input unit to the inspection device, and the inspection device has a receiving unit that receives the instructions transmitted from the terminal device and an execution unit that executes a first process that changes a function of the inspection device, based on the received instructions, which is not executed by instructions input from an input unit provided in the inspection device.

[0007] Moreover, one aspect of the present invention is an inspection device in an inspection system in which an inspection device for inspecting an object to be inspected and a terminal device are capable of communicating with each other, the inspection device having a receiving unit that receives instructions transmitted from the terminal device, and an execution unit that executes a first process that changes a function of the inspection device based on the received instructions, the first process being a process that is not executed based on instructions input from an input unit provided in the inspection device.

[0008] Moreover, one aspect of the present invention is a terminal device in an inspection system in which an inspection device that inspects an object to be inspected and a terminal device can communicate with each other, the terminal device having a first input unit that accepts input of an instruction to perform a first process that changes a function of the inspection device and is a process that is not performed by an instruction input from an input unit provided in the inspection device, and a transmission unit that transmits the instruction input from the first input unit to the inspection device.

[0009] Moreover, one aspect of the present invention is a method for executing a function change in an inspection system in which an inspection device for inspecting an object to be inspected and a terminal device are capable of communicating with each other, in which the terminal device executes a first input step of accepting input of instructions for the inspection device and a transmission step of transmitting the instructions input in the first input step to the inspection device, and the inspection device executes a receiving step of receiving instructions transmitted from the terminal device and an execution step of executing, based on the received instructions, a first process that changes a function of the inspection device and is not executed based on instructions input from an input unit provided in the inspection device.

[0012] An inspection system S according to an embodiment of the present invention will be described below with reference to the drawings. 1 is a schematic block diagram showing the configuration of an inspection system S according to an embodiment of the present invention. In the inspection system S, an inspection device 10 and a terminal device 20 are communicably connected via a network NW. The inspection device 10 is provided with a nozzle 10a, and detects gas by taking in external gas from the nozzle 10a and measuring the gas. This inspection device 10 is a handy type, and an inspector can hold it in one hand and inspect for gas leakage by bringing the tip of the nozzle 10a into contact with or close to an inspection point on an inspection target W.

[0013] The inspection object W is an object from which gas may leak. The inspection object W may be, for example, any of a gas pipe, a container, a sheet member, etc. With regard to the sheet member, there are some in which one end of at least a part of the sheet is joined to the other end to form a bag shape, and such a joint may be inspected. The inspection location is a portion of the inspection object W that is determined as the target for inspection.

[0014] For example, the inspection device 10 takes in gas near the inspection target W from an opening provided at the tip of the nozzle 10a and measures the concentration of the type of gas to be detected. An inspector holds the inspection device 10 and moves the nozzle 10a close to the outer surface of the inspection target W or along the outer surface of the inspection target W, thereby allowing the inspection device 10 to measure the gas leaking to the outside of the inspection target W. In addition, for example, the inspection device 10 can be moved so that the opening of the inspection device 10 moves along the outer surface of the inspection target W, and the position of the inspection target W where a leak is occurring (for example, the position of a hole opened in the inspection target W) can be detected based on the position of the nozzle 10a and the measured gas concentration. In this embodiment, the type of gas to be detected by the inspection device 10 is hydrogen gas, and the inspection device 10 measures hydrogen gas.

[0015] The inspection device 10 also includes a communication unit 101, a suction unit 102, a measurement unit 103, an input unit 104, an output unit 105, an execution unit 106, a control unit 107, and a storage unit 108. The communication unit 101 is communicably connected to the terminal device 20 via the network NW, and transmits and receives various data. The transmission unit 1011 transmits various data to the terminal device 20. For example, the transmission unit 1011 transmits a measurement value measured by the measurement unit 103 to the terminal device 20. The receiving unit 1012 receives various data including instructions transmitted from the terminal device 20 .

[0016] The suction unit 102 sucks gas outside the inspection device 10 from the nozzle 10a into the inspection device 10. The suction unit 102 is, for example, a suction pump connected to a suction path of the nozzle 10a.

[0017] The measurement unit 103 is a sensor that measures the gas sucked by the suction unit 102 and detects the target gas based on the measurement result. For example, the measurement unit 103 measures the gas flowing out from the inspection target W, detects the target gas contained in the gas based on the measurement result, and obtains a measurement value indicating the concentration of the target gas.

[0018] The input unit 104 accepts operational input from an inspector. The output unit 105 outputs various data. For example, the output unit 105 has a liquid crystal drive circuit and a liquid crystal display panel, and generates a drive signal from the liquid crystal drive circuit based on output data (e.g., image data) output from the control unit 107, and outputs the drive signal to the liquid crystal display panel. The liquid crystal display panel displays an image according to the image data by driving the elements of each pixel according to the drive signal output from the liquid crystal drive circuit. Here, the input unit 104 and the output unit 105 may be configured with a touch panel. The input unit 104 may have various input buttons in addition to the touch panel.

[0019] The execution unit 106 executes a first process for changing the function of the inspection device 10, which is not executed based on an instruction input from the input unit 104 provided in the inspection device 10, based on an instruction received by the receiving unit 1012 of the communication unit 101. In other words, the first process is a process that can be executed in response to an instruction from an administrator who operates the terminal device 20, and is a process that is not executed based on an instruction from an inspector of the inspection device 10. The first process is a process of changing a function of the inspection device 10, which, when changed, affects the quality of the inspection using the inspection device 10. For example, the first process may be any of a process of changing a reference value used to determine whether an inspection result obtained by measuring a gas by the measurement unit 103 is normal or abnormal, a process of performing sensitivity calibration, and the like. When the reference value is changed, the result of determining whether the measurement value measured by the measurement unit 103 is normal or abnormal may differ, which may affect the quality of the inspection. When sensitivity calibration is performed, the measurement value measured by the measurement unit 103 may differ from that obtained before the sensitivity calibration is performed, which may affect the quality of the inspection.

[0020] An example of a case where the reference value is changed is when the inspection object W to be inspected by the inspection device 10 is changed to a different type of inspection object W. By changing the reference value in this way according to the type of the inspection object W, it is possible to correctly determine whether the measurement value is normal or abnormal according to the type. Sensitivity calibration may be performed, for example, when the sensor wears out, changes over time, is affected by the environment, etc. By performing sensitivity calibration at the required time and according to the correct procedure, highly accurate measurement values ​​can be obtained, and the quality of the test can be maintained or improved. In this case, it is possible to prevent a decrease in measurement accuracy and a decrease in test quality due to sensitivity calibration being performed regardless of the administrator's intentions or according to an incorrect procedure.

[0021] The first process is classified into two types: one that requires a password, and one that does not require a password.

[0022] Furthermore, execution unit 106 executes a second process of changing a function of inspection device 10, which is executable based on an instruction input from input unit 104 provided in inspection device 10, based on an instruction input through input unit 104. In other words, the second process is executable in response to an instruction from an inspector operating inspection device 10, and is not executed based on an instruction from an administrator of terminal device 20. The second process is a process of executing a change of a function that does not affect the quality of the inspection using the inspection device 10 even if the function of the inspection device 10 is changed. For example, the second process may be any of a process of changing the brightness of a backlight that illuminates the display screen of the output unit 105 of the inspection device 10, a process of changing the volume of an output sound that indicates whether the inspection result is normal or abnormal, output from a headphone connected to the inspection device 10, and the like. Even if the brightness of the backlight of the output unit 105 is changed, the inspection result is not affected, so the quality of the inspection is not affected. Even if the volume of the headphone is changed, the inspection result is not affected, so the quality of the inspection is not affected. The brightness of the backlight and the volume of the headphone are changed by an inspector who actually operates the inspection device 10, so that if they are changed by an administrator remotely, it is possible to prevent an unintended change to the settings that would make it difficult to use the inspection device 10.

[0023] Furthermore, execution unit 106 executes a third process for changing the function of inspection device 10, which is executable based on either an instruction input from input unit 104 provided in the inspection device or an instruction received by receiving unit 1012, based on the instruction received by receiving unit 1012 or an instruction input through input unit 104. That is, the third process is executable based on an instruction from an inspector operating inspection device 10 or an instruction from a manager operating terminal device 20. The third process is a process of executing a change in function that does not affect the quality of the inspection using the inspection device 10 even if the function of the inspection device 10 is changed. For example, the third process may be any of the following processes: a process of changing the volume of an alarm sound output from a speaker provided in the inspection device 10, which indicates whether the inspection result shows normal or abnormal, a process of changing a button volume, which is the volume of a button operation sound output in response to pressing a button when an operation input is made from the input unit 104 of the inspection device 10, and the like. Even if the volume of the alarm sound is changed, the inspection result is not affected, so the quality of the inspection is not affected. Even if the volume of the button operation sound is changed, the inspection result is not affected, so the quality of the inspection is not affected.

[0024] The control unit 107 controls each unit of the inspection device 10. For example, the control unit 107 transmits a measurement value (inspection result) obtained based on the result of gas detection by the inspection device 10 to the terminal device 20 via the communication unit 101.

[0025] The storage unit 108 stores various data. For example, the storage unit 108 stores a reference value. The reference value is a value that serves as a criterion for determining whether the test result obtained by measuring the gas by the measurement unit 103 is normal or abnormal.

[0026] The terminal device 20 includes a communication unit 201, a data acquisition unit 202, an input unit 203, an output unit 204, a determination unit 205, a control unit 206, and a storage unit 207. The terminal device 20 may be, for example, any of a smartphone, a mobile phone, a tablet terminal, a PC (personal computer), and the like. The communication unit 201 is communicably connected to the inspection device 10 via the network NW, and transmits and receives various data. The communication unit 201 includes a transmitting unit 2021 and a receiving unit 2022 . The transmission unit 2021 transmits various data including the instructions input from the first input unit 2031 of the input unit 203 to the inspection device 10. When the determination unit 205 determines that the password is correct, the transmission unit 2021 transmits the instructions input from the first input unit 2031 to the inspection device 10. Here, when the instruction input from the first input unit 2031 is an instruction for the first process (password required), if the judgment unit 205 judges that the password is correct, the transmission unit 2021 transmits the instruction input from the first input unit 2031 to the inspection device 10. In addition, when the instruction input from the first input unit 2031 is an instruction for the first process (no password required) or the third process, the transmission unit 2021 transmits the instruction input from the first input unit 2031 to the inspection device 10 without accepting input of a password.

[0027] The receiving unit 2022 receives various data transmitted from the inspection device 10. For example, the receiving unit 2022 receives a measurement value measured by the measuring unit 103. When the measurement value is received, the control unit 206 writes the measurement value in the memory unit 207 to store it.

[0028] The data acquiring unit 202 acquires various data from the inspection device 10 via the communication unit 201. For example, the data acquiring unit 202 acquires a measurement value (inspection result) obtained by performing an inspection to detect gas flowing out from the inspection target W by the measurement unit 103.

[0029] The input unit 203 receives input of various data. The input unit 203 includes a first input unit 2031 and a second input unit 2032. The first input unit 2031 accepts input of instructions for the inspection device 10. The second input section 2032 accepts the input of a password.

[0030] The output unit 204 outputs various data. For example, the output unit 204 has a liquid crystal drive circuit and a liquid crystal display panel, and generates a drive signal from the liquid crystal drive circuit based on output data (e.g., image data) output from the control unit 206, and outputs the drive signal to the liquid crystal display panel. The liquid crystal display panel displays an image according to the image data by driving the elements of each pixel according to the drive signal output from the liquid crystal drive circuit. Furthermore, the output unit 204 can display information that cannot be displayed by the output unit 105 of the inspection device 10, based on the control from the control unit 206. For example, the output unit 204 can display a graph showing the relationship between the passage of time and the measurement value, based on the time-series data of the inspection result received from the inspection device 10. The inspection device 10 can display the measurement value, which is the inspection result, on the output unit 105, but does not display the graph showing the relationship between the passage of time and the measurement value. Here, the input unit 203 and the output unit 204 may be configured with a touch panel.

[0031] The determination unit 205 determines whether or not the password input from the second input unit 2032 is correct. Here, the correct password is stored in advance in the storage unit 207. The determination unit 205 determines whether or not the password stored in the storage unit 207 matches the password input from the second input unit 2032, thereby determining whether or not the password input from the second input unit 2032 is correct.

[0032] The control unit 206 controls each unit of the terminal device 20 . For example, the control unit 206 writes the test results acquired by the data acquisition unit 202 into the storage unit 207 to store them.

[0033] The storage unit 207 stores various data. For example, the storage unit 207 stores a measurement value received from the inspection device 10. The storage unit 207 also stores a password in advance. The storage unit 207 also stores rule information.

[0034] FIG. 2 is a diagram showing an example of rule information stored in the storage unit 207. As shown in FIG. The rule information is data in which functions and types are associated with each other. The function indicates a function installed in the inspection device 10. The type indicates a type of processing, and there are three types, a first processing, a second processing, and a third processing, and the first processing is further classified into a type that requires a password and a type that does not require a password.

[0035] For example, in the rule information shown in this figure, function A is associated with the first process (password required), which indicates that only administrators with special authority can change the function. Function B is associated with the first process (no password required), which indicates that any administrator can change the function regardless of authority. Since the second process is associated with function C, it is possible for the inspector to change the function. Function D is associated with the third process, which indicates that an inspector or a manager can change the function.

[0036] The network NW may be any of the Internet, a LAN (Local Area Network), etc., or a combination of these. The network NW may be any of wired and wireless, or a combination of these. Here, the inspection device 10 and the terminal device 20 may be connected by short-range wireless communication, as long as they can be connected to each other so as to be able to communicate with each other. The short-range wireless communication may be, for example, Bluetooth (registered trademark).

[0037] Next, the operation of the inspection system S will be described. 3 is a flowchart for explaining the operation of the terminal device 20. This flowchart is executed, for example, when a menu for receiving an operation input for changing a function of the inspection device is selected from among operation menus selectable in the terminal device 20. The operation menu is displayed on a touch panel configured by the input unit 203 and the output unit 204, and is a list showing operation contents for executing various functions of the terminal device 20. When the operator touches any of the functions in the list displayed as such an operation menu via the touch panel, the terminal device 20 receives an instruction to execute the function.

[0038] When the administrator changes the function of the inspection device 10 on the terminal device 20, the administrator transmits a connection request to the inspection device 10 whose function is to be changed via the network NW, and connects to the inspection device 10 so as to be able to communicate with the inspection device 10. Here, the inspection device 10 transmits to the terminal device 20 a list of processes that are not displayed on the output unit 105 of the inspection device 10 (processes that are not permitted to be operated from the inspection device 10) but can be displayed on the output unit 204 of the terminal device 20. This list includes items (e.g., function A, function B, etc.) for which the first process can be specified. Furthermore, the inspection device 10 transmits to the terminal device 20 a list of processes that are displayed on the output unit 105 of the inspection device 10 (processes that are permitted to be operated from the inspection device 10) and that can also be displayed on the output unit 204 of the terminal device 20. This list includes items that can specify the third process (for example, function D, etc.). The control unit 206 of the terminal device 20 causes the list received from the inspection device 10 to be displayed on the output unit 204. This allows the administrator to select a process to be operated from the list displayed on the output unit 204 (input an operation related to a change of a function).

[0039] The first input section 2031 of the input unit 203 of the terminal device 20 accepts an operation input related to a change of a function, which is input by an administrator (step S101). The control unit 206 judges whether the type of function change input from the first input unit 2031 is the first process (password required) by referring to the rule information stored in the storage unit 207 (step S102). For example, the control unit 206 identifies which function the instruction input from the first input unit 2031 is, reads out the type corresponding to the identified function based on the rule information stored in the storage unit 207, and judges whether the read out type is the first process (password required). More specifically, when the control unit 206 identifies that the function input from the first input unit 2031 is function A, it can read out that the corresponding type is the first process (password required) by referring to the rule information if it is function A, and thus judges that the instruction input from the first input unit 2031 is the first process (password required) (step S102-YES).

[0040] On the other hand, when the control unit 206 identifies that the function input from the first input unit 2031 is function B or function D, it can specify that the function is the first process (password not required) if it is function B, and that the function is the third process if it is function D, by referring to the rule information. In this case, the control unit 206 determines that the instruction input from the first input unit 2031 is not the first process (password required) (step S102-NO).

[0041] If it is determined in step S102 that the first process (password required) is not to be performed, the control unit 206 causes the transmission unit 2021 to transmit the instruction input from the first input unit 2031. The transmission unit 2021 transmits the instruction input from the first input unit 2031 to the inspection device 10 under the control of the control unit 206 (step S103). Here, regardless of whether the person is an administrator with special authority, the person can cause the inspection device to change its functions.

[0042] After the data is transmitted in step S103, the control unit 206 determines whether or not to terminate the operation input acceptance process of instructions to the inspection device (step S104). If the operation input acceptance process is to be terminated (if a menu other than the operation input acceptance process is selected, if an instruction to turn off the power has been input, etc.), it terminates the operation input acceptance process (step S104-YES). If the measurement is not to be terminated (if the menu for the operation input acceptance process remains selected, if an instruction to turn off the power has not been input, etc.) (step S104-NO), the process proceeds to step S101.

[0043] On the other hand, if it is determined in step S102 that the instruction input from the first input unit 2031 is the first process (password required), the control unit 206 causes the output unit 204 to display an input screen for inputting a password. After checking this password input screen, the administrator inputs a password. The second input unit 2032 accepts the input of a password based on the operation content from the administrator (step S110).

[0044] The determination unit 205 determines whether the password input from the second input unit 2032 is correct or not based on whether the password matches the password stored in the storage unit 207 (step S111). If the password input from the second input unit 2032 matches the password stored in the storage unit 207, the determination unit 205 determines that the password is correct (step S111-YES), and if they do not match, the determination unit 205 determines that the password is incorrect (step S111-NO).

[0045] If the control unit 206 determines that the password is correct, it causes the transmission unit 2021 to transmit the instruction input from the first input unit 2031. Here, the instruction input from the first input unit 2031 includes, for example, an instruction to specify the function to be changed and an instruction indicating the change content. For example, the function to be changed may be "change of reference value" and the change content may be "changed reference value". Alternatively, for example, the function to be changed may be "execution of sensitivity calibration" and the change content may be "operation content for calibrating sensitivity". Here, any function that is the first process (password required) may be used.

[0046] The transmission unit 2021 transmits the instruction input from the first input unit 2031 to the inspection device 10 under the control of the control unit 206 (step S103). The transmitted instruction includes an instruction to specify the function to be changed and an instruction to indicate the change content. In this way, if it is determined that the administrator who inputted the instruction is an administrator with special authority, the function can be changed.

[0047] On the other hand, if the control unit 206 determines that the password is incorrect, it does not transmit the instruction input from the first input unit 2031, and instead displays an error screen by the output unit 204 (step S112). This makes it possible to determine that the administrator who input the instruction is an administrator without special authority, and to prevent the function from being changed. If a certain period of time has elapsed after the error screen is displayed by the output unit 204, the control unit 206 transitions the process to step S104.

[0048] Next, the operation of the inspection device 10 will be described. FIG. 4 is a flowchart illustrating the operation of the inspection device 10. The control unit 107 of the inspection device 10 judges whether or not an input of an instruction for function change has been accepted by the input unit 104 (step S201). When an instruction for function change is input from the input unit 104 by the inspector, the input unit 104 accepts this operation input. When an instruction for function change is input from the input unit 104, the control unit 107 judges that an instruction has been input from the input unit 104 (step S201-YES), and accepts the input of the instruction for function change input from the input unit 104 (step S202). Here, a list of functions of the second process or the third process is displayed on the menu screen as an instruction that can be input from the input unit 104, and the inspector can specify a change of the target function to be executed from the list. In this way, the control unit 107 can display different combinations of process types included in the menu depending on whether the device to which the instruction for function change is input is the inspection device 10 (e.g., the input unit 104) or the terminal device 20 (e.g., when the instruction for function change transmitted from the terminal device 20 is received by the receiving unit 1012). Therefore, the input of the instruction for the first process is prevented from being made by the inspector of the inspection device 10, and the input of the instruction for the second process is prevented from being made by the administrator of the terminal device 20. Then, the control unit 107 outputs the instruction regarding the function change input from the input unit 104 to the execution unit 106 .

[0049] When the execution unit 106 acquires from the control unit 107 an instruction regarding the function change inputted from the input unit 104, the execution unit 106 executes the change of the function of the inspection device 10 based on the acquired instruction (step S203).

[0050] When the function change is executed in step S203, the control unit 107 determines whether or not to terminate the processing (step S204). If the processing is to be terminated (e.g., if an instruction to turn off the power has been input), the control unit 107 terminates the processing (step S204-YES). If the processing is not to be terminated (e.g., if an instruction to turn off the power has not been input) (step S204-NO), the control unit 107 transitions to step S201.

[0051] If no instruction regarding function change has been input from the input unit 104 (step S201-NO), the control unit 107 judges whether or not the receiving unit 1012 has received an instruction regarding function change from the terminal device 20 (step S211). If the receiving unit 1012 has received an instruction regarding function change from the terminal device 20 (step S211-YES), the control unit 107 accepts the instruction regarding function change received by the receiving unit 1012 from the terminal device 20 (step S212). The instruction regarding function change received here includes an instruction regarding function change that is the first process or the third process. Then, the control unit 107 outputs the instruction regarding function change received by the receiving unit 1012 to the execution unit 106.

[0052] When the execution unit 106 acquires an instruction for function change received by the receiving unit 1012 from the control unit 107, the execution unit 106 executes the change of the function of the inspection device 10 based on the acquired instruction (step S203). For example, the execution unit 106 executes the change of the function based on an instruction specifying the function to be changed and an instruction indicating the change content, which are included in the acquired instruction. For example, when "change of reference value" is instructed as the function to be changed and "changed reference value" is instructed as the change content, the execution unit 106 performs the change process of the reference value by updating the reference value stored in the memory unit 108 to the specified changed reference value. On the other hand, in step S211, if the receiving unit 1012 has not received an instruction regarding the function change from the terminal device 20 (step S211-NO), the control unit 107 shifts the process to step S201.

[0053] 5, 6, and 7 are diagrams showing examples of display screens displayed on the output unit 204. FIG. In FIG. 5, a list of operations that the administrator can operate is displayed. The administrator performs an operation input to select the "settings" button (reference number 50) from this list, and then performs an operation input to select the "Advanced settings" menu (reference number 51), which is the first process (password required). As a result, the display screen switches from the display screen in FIG. 5 to a display screen for entering a password shown in FIG. 6. The administrator enters the password by operating the numeric keypad displayed on the screen. For example, the password is a four-digit number. If the entered password is correct, the display screen switches from the display screen shown in FIG. 6 to the display screen shown in FIG. 7. In FIG. 7, a list of selectable processes in "Advanced settings" is displayed. The administrator can select one of the buttons in this list, such as sensitivity calibration (reference number 60) or threshold and change of its value (reference number 61), and perform an operation input. In addition, the display screen in FIG. 7 also displays a selection button (reference number 62) for selecting whether or not a password is required to be entered. Here, the function of "Advanced settings" can be used by an administrator with special authority who enters a password. However, if there is no need to distinguish between an administrator and an inspector, and a password is not required, the selection button (reference number 62) may be switched to "no password required." After switching to "no password required," when "Advanced settings" on the display screen in FIG. 5 is selected, the display screen shown in FIG. 7 may be transitioned to without displaying the display screen for entering a password shown in FIG. 6. In this case, the mode is switched to one in which operations such as sensitivity calibration and change of a threshold and its value can be performed without entering a password. In addition, when the selection button (symbol 62) is operated to switch from "no password required" to "password required," the "Advanced settings" function switches to a mode that can be used by an administrator with special authority by entering a password.

[0054] According to the embodiment described above, for processing to change functions that may affect the quality of the inspection, input is received from the terminal device 20, and input is not received from the inspection device 10. This makes it possible to clearly separate the authority of the inspector who operates the inspection device 10 and the administrator who operates the terminal device 20.

[0055] According to the embodiment described above, before the inspection device 10 executes an instruction regarding the first process, the user is asked to input a password, and if the input password is correct, the first process is executed. Therefore, when the first process is executed, the user is limited to input from an administrator who knows the correct password. This makes it possible to further narrow down the administrators who can input from among a plurality of administrators. Here, the case where the administrator inputs a password to determine whether the administrator has authority or not has been described, but when determining whether the administrator has authority or not, an authentication method other than password input may be used as long as it is an authentication method using authentication information. In this case, the authentication method may be, for example, biometric authentication (fingerprint authentication, face authentication, voiceprint authentication, iris authentication, etc.).

[0056] In the above embodiment, the determination unit 205 is provided in the terminal device 20. However, the function of the determination unit 205 may be provided in the inspection device 10 instead of the terminal device 20. In this case, the correct password is stored in advance in the storage unit 108. Then, the transmission unit 2021 transmits the password input from the second input unit 2032 and the instruction regarding the change of the function input from the first input unit 2031 to the inspection device 10. The reception unit 1012 of the inspection device 10 receives the password and the instruction regarding the change of the function, and the judgment unit of the inspection device 10 judges whether the password is correct or not based on whether the received password matches the password stored in the storage unit 108. If it is judged that the password is correct, the execution unit 106 executes the change of the function of the inspection device 10 based on the instruction regarding the change of the function received from the terminal device 20. If it is judged that the password is incorrect, the execution unit 106 does not execute the change of the function of the inspection device 10 based on the instruction regarding the change of the function received from the terminal device 20. In this case, the control unit 107 may notify the terminal device 20 of error information via the communication unit 101. As a result, an error screen is displayed on the output unit 204 of the terminal device 20.

[0057] In the embodiment described above, the reference value used to determine whether or not gas leakage is occurring is changed based on an instruction from the terminal device 20. Therefore, the inspector operating the inspection device 10 cannot arbitrarily change the reference value, but can change the reference value based on an instruction from a person authorized to set the reference value. This makes it possible to prevent the inspection result from being unintentionally changed, and to prevent any influence on the inspection result. Therefore, a high-quality leak inspection can be performed.

[0058] Furthermore, according to the embodiment described above, the execution unit 106 executes the first process, which is not executed even if various instructions are input from the input unit 104 of the inspection device 10, based on an instruction input from the input unit 203 of the terminal device 20 and received from the terminal device 20. As a result, the first process is not executed even if an inspector using the inspection device 10 inputs an operation from the input unit 104 provided in the inspection device 10, but the first process can be executed when an instruction is received from the terminal device 20. Therefore, it is possible to distinguish between the authority to execute the first process between the inspector using the inspection device 10 and the administrator using the terminal device 20.

[0059] Furthermore, in the above embodiment, the first process is described as changing the reference value and performing sensitivity calibration, but the process may be such that the terminal device 20 transfers the inspection results received from the inspection device 10 to a terminal device other than the terminal device 20. This allows the inspection results that should be transferred to another terminal device to be transferred according to the administrator's judgment.

[0060] The communication unit 101, measurement unit 103, input unit 104, output unit 105, execution unit 106, and control unit 107 of the above-mentioned inspection device 10 may be configured, for example, by a processing device such as a CPU (Central Processing Unit) or a dedicated electronic circuit. The communication unit 201, data acquisition unit 202, first input unit 2031, second input unit 2032, output unit 204, judgment unit 205, and control unit 206 of the terminal device 20 may be configured, for example, by a processing device such as a CPU (Central Processing Unit) or a dedicated electronic circuit.

At least one of the storage unit 108 and the storage unit 207 can use, for example, a non-volatile memory.
