Description

The present invention relates to a measurement system and a measurement device.

Patent Document 1 shows a tester. This tester has a function of displaying the measurement results on a display unit and a function of storing the measurement results in a memory.

U.S. Pat. No. 1,039,3815

In such measuring devices such as testers, there are cases where you want to know information about the measurement on a terminal other than the measuring device. In such cases, communication is required between the measuring device and the terminal.

Generally, the procedure for such communication involves one device sending a command to another device requesting information, and the other device receiving this command then sending the information to the first device.

However, when this type of communication procedure is applied to a measurement system, the measurement device that transmits the information must constantly perform reception processing to receive commands. In addition, the measurement device must perform information transmission processing every time it receives a command.

As a result, the load on the measurement device for reception and transmission processing increases, which may affect measurement processing.

The present invention has been made in consideration of the above problems, and has an object to provide a measurement system and a measuring device that are capable of suppressing the effects that may be exerted on the measurement process.

According to one aspect of the present invention, there is provided a measurement system in which a measuring device and a terminal are configured to be able to communicate with each other, the measuring device includes a measuring means for executing a measurement process to measure a physical quantity of a measurement target, a detecting means for detecting the execution of the measurement process, and a transmission permission means for permitting the transmission of a measurement result to the terminal when the detecting means detects the execution of the measurement process, and the terminal includes a result receiving means for receiving the measurement result from the measuring device, and an execution means for executing a predetermined process based on the received measurement result.

In this embodiment, the measuring device is permitted to transmit the measurement results to the terminal upon detecting the execution of a measurement process.

This makes it possible to reduce the amount of reception and transmission processing that may occur during the measurement process, compared to when request commands from the terminal must be constantly accepted and measurement results must be sent to the terminal each time a request command is accepted.

This makes it possible to reduce the impact that may be caused to the measurement process.

(Function block)
FIG. 4 is a functional block diagram showing the functions of each part of the measurement system 10 according to one embodiment.

[Measuring Instrument]
Measuring device 12 of measurement system 10 includes a receiving unit 60 constituting a receiving means, a measuring unit 62 constituting a measuring means, a storage unit 64 constituting a storage means, a notifying unit 66 constituting a notifying means, and a deleting unit 68 constituting a deleting means. Measuring device 12 of measurement system 10 also includes a detecting unit 70 constituting a detecting means, and a transmission permitting unit 72 constituting a transmission permitting means.

The receiving unit 60 receives specific information from the terminal 14 via the communication unit 34.

The notification unit 66 notifies the identifiers of each of the measurement target groups in order based on the specific information. In addition, when the deletion unit 68 performs deletion, the notification unit 66 notifies the identifier associated with the deleted stored data.

The measurement unit 62 executes a measurement process to measure the physical quantity of the measurement target. The detection unit 70 detects the execution of the measurement process by the measurement unit 62. The transmission permission unit 72 permits the transmission of the measurement results to the terminal 14 when the detection unit 70 detects the execution of the measurement process.

When the measurement unit 62 is used to measure the physical quantity of the measurement target based on the specific information received from the terminal 14, the storage unit 64 stores stored data based on the measurement results of the measurement target by the measurement unit 62 in the memory unit 32 in association with the specific information.

Specifically, the storage unit 64 associates and stores the subject group identification information, which is information about the measurement subject group, together with the identifier to each stored data of the measurement subject group by the measurement unit 62 based on the identification information. In addition, each time the notification unit 66 notifies the identifier of the measurement subject, the storage unit 64 stores the stored data in association with the notified identifier.

The deletion unit 68 deletes the stored data and identifier last stored by the storage unit 64 in response to operational input by the person performing the measurement.

As another function, the measuring device 12 transmits to the terminal 14 the identifier that the notification unit 66 will next notify. In addition, the measuring device 12 notifies the terminal 14 of the end of storage when the storage process by the storage unit 64 is completed.

In this embodiment, the functions of each part of the measuring device 12 are realized by the control unit 20 executing a program read from the memory unit 32.

[Device]
The terminal 14 of the measurement system 10 includes a transmitting unit 80 constituting a transmitting means, a generating unit 82 constituting a generating means, a result receiving unit 84 constituting a result receiving means, and an executing unit 86 constituting an executing means.

The generating unit 82 generates specific information according to the input from the input unit 58. The transmitting unit 80 transmits the specific information that identifies the measurement target of the measuring device 12 to the measuring device 12 via the communication unit 63.

The result receiving unit 84 receives the measurement results from the measuring device 12 via the communication unit 63. The execution unit 86 executes a predetermined process based on the received measurement results. Examples of the predetermined process include displaying the measurement results or providing guidance on the measurement subject.

When the terminal 14 receives an identifier from the measuring device 12, it reports the received identifier. When the terminal 14 is notified by the measuring device 12 that storage has ended, it reports the next identifier to be reported. The terminal 14 then reports the identifier of the measurement target by sound.

In this embodiment, the functions of each part of the terminal 14 are realized by the control unit 50 executing a measurement program read from the memory unit 61.

(Operation description)
Next, the operation of the measurement system 10 will be described with reference to Figures 5 to 17. The following describes the processing procedure executed by the processor of the control unit 20 in the measuring device 12 and the processing procedure executed by the processor of the control unit 50 in the terminal 14.

In this embodiment, an example is described in which each battery 40 of an uninterruptible power supply 38 (UPS (Uninterruptible Power Supply)) installed in each room is measured (see FIG. 2). However, this is not limited to this, and the device may be used to measure the voltage, current, or resistance of each location of the measurement target.

Figure 5 is a flowchart showing the operation of the measurement system 10 according to one embodiment. Figure 6 is a flowchart showing the operation following that of Figure 5, and Figure 7 is a flowchart showing the operation following that of Figure 6.

When starting measurement of the battery 40 of the uninterruptible power supply 38, the processor of the control unit 20 of the measuring device 12 starts operating according to the program stored in the memory unit 32. Also, the processor of the control unit 50 of the terminal 14 starts operating according to the measurement program stored in the memory unit 61.

When the process of inputting and generating specific information is executed in the terminal 14, the terminal 14 inputs information for identifying the measurement target from the input unit 58 and generates the specific information (step ST1).

Here, the specific information will be explained using FIG. 17. Details of FIG. 17 will be described later. Also, the specific information 90 can be referred to as profile information.

This specific information 90 includes profile number information 92 indicating the number of the specific information 90, subject group specific information 96, and an identifier 98 for managing each of the measurement subject groups.

The profile number information 92, which is the specific information 90, includes a profile number 91, and as an example, the profile number information 92 is composed of the number "1" which indicates a number for identifying the specific information 90.

The target group identification information 96 includes, as an example, location information 100 indicating the installation location of the measurement target, and the location information 100 is composed of room information 102 for identifying the room in which the measurement target group is installed. As an example, the room information 102 is composed of the character string "HIOKI 1F UPS ROOM" indicating the company name, floor number, and room name.

The target group identification information 96 includes, as an example, device information 104 that indicates the target object to be measured, and the device information 104 is composed of type information 106 that indicates the type of device. As an example, the type information 106 is composed of the character string "UPS1-1" to identify the installed uninterruptible power supply 38.

The identifier 98 is composed of a battery number 108 for identifying the battery 40, and as an example, the battery number 108 is composed of the numeral "1" which indicates the number assigned to each battery 40.

In this embodiment, the battery number 108 indicating the identifier 98 of the specific information 90 is composed of numbers, but this is not limited to this. For example, the identifier 98 may be composed of a character string.

The specific information 90 will be further explained using FIG. 9. Details of FIG. 9 will be described later.

This specific information 90 includes management information 110 that identifies the identifiers 98. The management information 110 is information for identifying a group of identifiers 98 that are set in the specific information 90 whose profile number 91 is "1". As an example, the management information 110 shows "1" indicating the start number 112 and "50" indicating the end number 114.

This specific information 90 is stored in each area allocated to the storage unit 32 constituting the memory of the measuring device 12, and there is a one-to-one correspondence between the multiple identifiers 98 identified by the management information 110 and the memory identifier 116 indicating the memory number 115 that identifies each area.

Specifically, the "1" of the identifier 98 specified by the management information 110 corresponds to the "A.001" of the memory identifier 116. Furthermore, the numbers "2" to "50" of the identifier 98 correspond to the "A.002" to "A.050" of the memory identifier 116, respectively.

Then, each piece of data in the area from "A.001" in memory number 115, indicated by the "1" in start number 112, to "A.050" in memory number 115, indicated by the "50" in end number 114, is stored as being associated with location information 100 and device information 104.

This reduces the amount of storage space used by the memory unit 32 compared to storing the measurement data 194 for each memory number 115 with the location information 100 and device information 104 added.

Next, the method for generating the specific information 90 in step ST1 shown in FIG. 5 will be specifically explained using FIG. 8.

Figure 8 is a diagram showing an example of a profile information editing screen 120 displayed on the terminal 14. When editing of the profile information is started on the terminal 14 to generate specific information 90, the profile information editing screen 120 is displayed on the display unit 54 of the terminal 14, as shown in Figure 8.

Following the display of this editing screen 120, the person making the measurement enters "1" indicating profile number 91 in the profile number field 122 of the editing screen, and also enters the character string "HIOKI 1F UPS ROOM" indicating the room information 102 of the room where the measurement will be performed in the location information field 124 indicating the location information 100.

In this embodiment, the case where the room information 102 of the specific information 90 is configured as a character string will be described, but the present invention is not limited to this. For example, the room information 102 indicating the location information 100 may be a mapping number set at each location on the floor map. In this case, the terminal 14 may display the floor map on the display unit 54 and display a mark at the location on the floor map indicated by the mapping number to indicate the installation location of the uninterruptible power supply 38.

The person who performs the measurement also enters the character string "UPS1-1" into the device information field 126, which indicates the type information 106 of the uninterruptible power supply 38 for which the measurement is to be performed.

Then, the person measuring enters "1" into the battery number field 128 to indicate the identifier of the battery number for which the first measurement will be performed, and enters "50" to indicate the identifier of the battery number for which the last measurement will be performed.

The person also inputs "A.001" indicating the memory identifier 116 in the memory number column 130 as the memory number 115 for identifying the area for storing the measurement results of the battery 40 for which the first measurement is performed and whose identifier 98 is "1" (see FIG. 17). The person also inputs "A.050" indicating the memory identifier 116 in the memory number column 130 as the memory number 115 for identifying the area for storing the measurement results of the battery 40 for which the last measurement is performed and whose identifier 98 is "50" (see FIG. 17).

These inputs can be made by touching the touch panel that constitutes the input unit 28, or by using a touch pen or the like.

When the measurer touches the "OK" button 132 on this editing screen 120, as shown in FIG. 5, the terminal 14 transmits specific information 90 to the measuring device 12 to identify the subject to be measured by the measuring device 12 (step ST2).

Then, the measuring device 12 receives the specific information 90 transmitted from the terminal 14 (step SS1) and registers the received specific information 90 (step SS2). This registration will be explained using FIG. 9.

Figure 9 is an explanatory diagram showing an example of the relationship between specific information 90 and the memory number 115 corresponding to the specific information 90, and shows the specific information 90 stored in the memory unit 32 of the measuring device 12.

The profile number 91 of this specific information 90 is stored as "1", indicating that this specific information 90 has a profile number 91 of "1". The location information 100 is stored as "HIOKI 1F UPS ROOM", and the device information field 104 stores "UPS1-1".

"1" is stored as the start number 112 of the battery number 108, and "A.001" is stored as the memory number 115 associated with this "1". Also, "50" is stored as the end number 114 of the battery number 108, and "A.050" is stored as the memory number 115 associated with this "50".

This specific information 90 with profile number 91 "1" is used to measure batteries 40 with battery numbers "1" to "50" of the uninterruptible power supply 38 of "UPS1-1" installed in "HIOKI 1F UPS ROOM".

The operation of this measuring device 12 when measuring the batteries 40 in the measurement target group will be explained using Figures 10 to 17.

Figure 10 is a diagram showing an example of a pre-measurement guide screen 140 displayed on the terminal 14 before measurement begins. Figure 11 is an explanatory diagram explaining an example of a notification screen 142 displayed on the terminal 14 and an audio guide from the terminal 14. Figure 12 is a diagram showing an example of a notification screen 142 displayed on the terminal 14 after measurement begins.

When starting measurement with the measuring device 12, as shown in FIG. 5, the profile number 91 to be used is input (step SS3), and the measurement record guide start button 146 is pressed (step SS4).

Specifically, as shown in FIG. 10, the pre-start measurement guide screen 140 displayed on the display unit 24 prompts the person to select the profile number 91 to be used for the person being measured. In response, the person to be measured selects, as an example, "1" in the profile number to be used field 148, and then touches the measurement record guide start button 149.

As shown in FIG. 5, the operation status of the measurement record guide start button 149 determines whether or not a measurement has started (step SS5). If it is determined that a measurement has not started, the process branches to step SS3, whereas if it is determined that a measurement has started, the process proceeds to the next step SS6.

The processing corresponding to steps SS3 to SS4 can also be performed on the terminal 14.

That is, the terminal 14 judges whether a start instruction has been given by, for example, detecting whether a start button to start measurement has been pressed (step ST3). If a start instruction has not been given, the process branches to step ST6, whereas if a start instruction has been given, the profile number 91 to be used is input in the same manner as in step ST3 (step ST4).

Then, when the measurement record guide start button 149 displayed on the terminal 14 is pressed, the input profile number 91 and a start signal are sent to the measuring device 12 (step ST5).

When the measuring device 12 receives the profile number 91 and the start signal from the terminal 14, it determines that measurement has started (step SS5) and proceeds to the next step SS6.

In step SS6, the measuring device 12 sets a measurement target number indicating the measurement target to be measured first from the specific information 90 of the profile number 91 selected by the measuring device 12 or the terminal 14, and stores the set measurement target number in the memory unit 32 (step SS6). Then, the measuring device 12 transmits the set measurement target number to the terminal 14 (step SS7) and notifies the terminal 14 of the measurement target number (step SS8).

The terminal 14 receives the measurement target number transmitted from the measuring device 12 and stores it in the memory unit 61 (step ST6), and also notifies the user of the received measurement target number by sound (step ST7).

Next, a specific example of a notification method for the measurement target method will be described with reference to Figs. 13 to 16. Fig. 13 is a diagram showing an example of a notification screen 150 for battery number "1" displayed on the display unit 24 of the meter 12. Fig. 14 is a diagram showing an example of a measurement result display screen 152 for battery number "1" displayed on the display unit 24 of the meter 12.

In step SS7 shown in FIG. 5, the measuring device 12 sets the measurement target number for the first measurement to be performed from the start number 112 of the battery number 108 to "1" in the specific information 90 for which the selected profile number 91 is "1", and transmits the set "1" to the terminal 14.

The measuring device 12 then outputs the voice message "GUIDE START" from the notification device 26 to notify the start of measurement. As shown in FIG. 13, the measuring device 12 also displays "NEXT BATTERY No." in the display content field 160 on the notification screen 150, and flashes "1", which is the battery number 108 of the battery being measured, in the battery number field 162.

The measuring device 12 then outputs the voice "NEXT BATTERY No. 1" to indicate that the next battery to be measured is battery 40 with battery number 108 of "1." It also displays "A.001" in the memory number column 164, indicating that the measurement results will be recorded in the area of memory number 115 for "A.001." In this way, the batteries 40 are measured in the order of battery number 108.

Figure 15 shows an example of a notification screen 150 that is displayed on the measuring device 12 when the battery number 108 is "50."

In step SS19 shown in FIG. 7, which will be described later, the measurement target number is counted up, and when the measurement target number becomes "50", step SS8 causes "NEXT BATTERY No." to be displayed in the display content field 160 of the notification screen 150 as shown in FIG. 15. Also, in the battery number field 162 of the notification screen 150, "50", which is the battery number 108 of the measurement target, is displayed in a flashing manner, and "NEXT BATTERY No. 50" is output as an audio message.

In addition, "A.050" is displayed in the memory number column 164 on the notification screen 150, indicating that the measurement results will be recorded in "A.050."

The total number of batteries 40 to be measured may be displayed on the notification screen 150 in FIG. 13 and FIG. 15.

Next, the operation of the terminal 14 will be described with reference to FIG. 11. FIG. 11 shows a notification screen 142 in which measurement of batteries 40 with battery numbers 108 ranging from "1" to "19" has been completed. In this notification screen 142, the next battery number to be recorded field 170 shows "20", which is the battery number 108 to be measured.

The terminal 14 notifies the start of measurement by outputting "GUIDE START" from the notification device unit 56. After that, the notification screen 142 displays "1" indicating the battery number 108, which is the identifier 98 of the measurement target, and outputs "NEXT BATTERY No. 1" as a voice, notifying that the next measurement target is battery 40, whose battery number 108 is "1."

As a result, in step SS7 shown in FIG. 5, the measuring device 12 transmits the identifier 98 to be reported next to the terminal 14, and when the terminal 14 receives the identifier 98 from the measuring device 12 in step ST6, it reports the received identifier 98 in step SS7.

Figure 12 is a diagram showing an example of the display of the measuring device 12. Figure 12 shows the case where the battery number 108 of the battery 40 to be measured next is "20."

On the notification screen 142 displayed on the display unit 24 of the measuring device 12, the battery number column 172 of the next battery number column 170 to be recorded displays "20," indicating that the next measurement target is battery 40, whose battery number is "20." In addition, the memory number column 174 displays "A.020," indicating that the measurement result will be recorded in "A.020."

The recorded battery number column 176 shows that the measurement results for battery numbers 108 from "1" to "19" have been recorded in each area of memory number 115 from "A.001" to "A.019."

The total number of batteries 40 to be measured may be displayed on the notification screen 142 in FIG. 12.

Next, as shown in FIG. 6, the measuring instrument 12 uses the measuring device unit 22 to execute a measurement process for measuring the physical quantity of the measurement target (step SS9), and detects whether the measurement process has been executed (step SS10). If the execution of the measurement process is detected, the process proceeds to the next step SS11, whereas if the execution of the measurement process is not detected, the process waits until it is detected.

To be more specific, as shown in FIG. 2, the person measuring performs the measurement by connecting the positive electrode probe 44 of the measuring device unit 22 to the positive electrode terminal 42 of the battery 40 to be measured, and connecting the negative electrode probe 48 to the negative electrode terminal 46 of the battery 40. At this time, the measuring device unit 22 applies a detection AC signal between the positive electrode probe 44 and the negative electrode probe 48, and detects whether or not an AC current corresponding to the detection AC signal flows between the two probes 44, 48. If an AC current is detected, it can be confirmed that the probes 44, 48 are connected to the terminals 42, 46 and are energized, and therefore it is determined that the measurement process has been performed.

When the execution of a measurement process is detected in step SS10 shown in FIG. 6, the measurement result is obtained, for example, once every 200 mS (seconds) (step SS11). Then, upon detection of the execution of this measurement process, transmission of the measurement result to the terminal 14 is permitted, and the measurement result is transmitted to the terminal 14 (step SS12).

Specifically, until the execution of the measurement process is detected in step SS10, the transmission of the measurement results to the terminal 14 is prohibited, and the prohibited state is released when the execution of the measurement process is detected.

In the prohibited state, even if the measuring device section 22 detects a signal due to noise or the like, the detection result is not adopted as the measurement result, and the measuring instrument 12 and terminal 14 display "----" as an example.

Then, after the execution of the measurement process is detected in step SS10, the detection result in the measurement device section 22 is adopted as the measurement result, and the measurement result is displayed on the measuring instrument 12 and the terminal 14.

The terminal 14 receives the measurement results sent from the measuring device 12 (step ST8), and displays the measurement results on the display unit 54 (step ST9). As a result, the terminal 14 executes a predetermined process based on the measurement results received from the measuring device 12.

The measurement results include a resistance value indicating the internal resistance of the battery 40, which is calculated from the current value flowing between the two probes 44, 48, and a voltage value of the battery 40, which is calculated from the potential difference generated between the two probes 44, 48. The measurement results also include a temperature value of the battery 40, which is calculated from the temperatures of the two probes 44, 48. Further measurement results include a judgment result obtained from the resistance value, voltage value, and temperature value described above, and in this embodiment, these resistance value, voltage value, temperature value, and judgment result are transmitted to the terminal 14 as measurement results.

As a result, the display unit 54 of the terminal 14 displays the resistance value, voltage value, temperature value, and judgment result transmitted as the measurement results.

The measuring device 12 also displays the measurement results on the display unit 24 (step SS13), and each time it acquires a resistance value, voltage value, or temperature value, which is a measurement of a physical quantity, as a measurement result, it adds the resistance value, voltage value, or temperature value as an integrated value using the memory area of the memory unit 32 (step SS14). It then determines whether a preset predetermined time has elapsed since the execution of the measurement process was detected (step SS15), and repeats steps SS11 to SS14 until the predetermined time has elapsed. As an example, the predetermined time is 1600 mS (seconds).

To be more specific, as shown in FIG. 14, a measurement result display screen 152 is displayed on the display unit 24 of the measuring device 12. On this measurement result display screen 152, the resistance value column 180 displays "1.000 mΩ" indicating the resistance value that is the measurement result, and the voltage value column 182 displays "12.00 V" indicating the voltage value that is the measurement result. Additionally, the judgment result column 184 displays "PASS" indicating that the judgment result that is the measurement result has passed.

Next, FIG. 16 is a diagram showing an example of a display screen of the measurement results of battery number "50" displayed on the measuring device 12. In this way, the measuring device 12 displays the measurement results of battery numbers "1" to "50" in order.

In step SS19 shown in FIG. 7, which will be described later, the measurement object number is counted up and the measurement object number becomes "50". In this case, as a result of the processing in step SS13, as shown in FIG. 16, the resistance value column 180 of the measurement result display screen 152 displays "1.000 mΩ" indicating the resistance value, which is the measurement result, and the voltage value column 182 displays "12.00 V" indicating the voltage value, which is the measurement result. In addition, the judgment result column 184 displays "PASS" indicating that the judgment result, which is the measurement result, is a pass.

Returning to FIG. 7, if the measuring device 12 determines in step SS15 that the predetermined time has elapsed, it acquires the stored data (step SS16). The stored data is data that is determined based on the measurement results obtained within a predetermined period after detecting the execution of the measurement process.

To be more specific, the integrated value stored in the memory unit 32 is the integration of the eight previously acquired resistance and voltage values. By dividing this integrated value by "8", the average value of the eight resistance and voltage values acquired over a period of 1600 mS (seconds) is obtained as stored data.

In this way, the measuring device 12 stores the acquired saved data in the memory unit 32 in association with the specific information 90 of the measurement subject from which the measurement results were acquired (step SS17). As a result, the measuring device 12 stores saved data based on the measurement results of the measurement subject in association with the specific information 90 based on the specific information 90 received from the terminal 14. The specific information 90 includes subject group specific information 96 and an identifier 98 of the measurement subject group.

Figure 17 is an explanatory diagram showing an example of data 190 stored in the measuring device 12, and shows the memory contents of an area in the memory unit 32 of the measuring device 12 where the memory number 115 is set to "A.001."

In the area of memory number 115 "A.001", profile information 192 indicating specific information 90 and measurement data 194 indicating the measurement results are stored in association with each other.

The profile number 91 of the profile information 192 is set to "1", and the character string "HIOKI 1F UPS ROOM" is stored as the location information 100 indicated by the room information 102 of the target group specific information 96 in the profile information 192.

The character string "UPS1-1" is stored as the device information 104 indicated by the type information 106 of the target group identification information 96 in the profile information 192, and the number "1" is stored as the battery number 108 indicated by the identifier 98 in the profile information 192.

The character string "A.001" is stored as the memory number 115 of the measurement data 194, and an example of the memory number 115 is the label of a memory address set in the memory area of the storage unit 32. The date and time 196 of the measurement data 194 is stored as "2020/4/20 13:00:00", which indicates the measurement time.

The resistance value 200 constituting the stored data 198 in the measurement data 194 is stored as "1.000" mΩ, and the voltage value 202 is stored as "12.00" V. The temperature value 204 constituting the stored data in the measurement data 194 is stored as "●●.●●" °C.

As the comparator threshold value 206 of the measurement data 194, an index selected from "mΩ" and "V" used to judge the measurement result is stored. In addition, as the judgment result 208 of the measurement data 194, one selected from "PASS" indicating a pass, "WARNING" indicating a warning, and "FAIL" indicating a fail is stored.

Then, as shown in FIG. 7, the measuring device 12 stores the data 190 in the memory unit 32, and then transmits the data 190 stored in the memory unit 32 to the terminal 14 (step SS18). This data 190 includes stored data 198, and the transmission of the data 190 indicates a notification that the measuring device 12 has finished storing the data 190.

The terminal 14 to which this data 190 is transmitted judges whether or not it has received the data 190 including the stored data 198 (step ST10). If it judges that it has received the data 190, it displays the stored data 198 on the display unit 54 (step ST11) and counts up the measurement object number stored in the memory unit 61 to identify the measurement object (step ST12).

Similarly, the measuring device 12 counts up the measurement target number stored in the memory unit 32 (step SS19).

Then, the measuring device 12 determines whether, for example, the data clear button has been operated (step SS20), and if it determines that the data clear button has not been operated, it branches to step SS24.

In addition, when the person measuring operates the data clear button provided on the measuring device 12, it is determined in step SS20 that the data clear button has been operated, and the saved data 198 and data 190 including the identifier 98 last saved in the memory unit 32 are deleted (step SS21).

Furthermore, the measuring device 12 counts down the measurement target number in the memory unit 32 (step SS22), transmits a notification to the terminal 14 that the measurement target number has been counted down (step SS23), and then proceeds to step SS24.

In this embodiment, only the function of deleting the last saved data 190 in response to an operation input has been described, but the present invention is not limited to this. For example, the present invention may be provided with a function of skipping the next measurement target in response to an operation input.

Meanwhile, the measuring device 12 determines whether or not it has received a countdown notification (step ST13), and if it determines that it has not received a countdown notification, it branches to step ST15. If it determines in step ST13 that it has received a countdown notification, it counts down the measurement target number in the memory unit 61 (step ST14). Then, it determines whether or not the measurement is complete based on whether or not the measurement target number has reached the end number 114 indicating the end value of the battery number 108 in the specific information 90 (step ST15).

If it is determined in step ST15 that the measurement target number has reached the end number 114 and the measurement is complete, the measurement process ends. Also, if it is determined in step ST15 that the measurement target number has not reached the end number 114 and the measurement is not complete, the process branches to step ST7 and reports the measurement target number.

As a result, when the data 190 including the saved data 198 and the identifier 98 last saved in the memory unit 32 is deleted, the identifier 98 associated with the deleted saved data 198 is notified (step ST7).

On the other hand, if the data 190 last stored in the memory unit 32 is not deleted, the identifier 98 indicated by the measurement object number counted up in step ST12 is notified (step ST7). As a result, the identifiers 98 of each of the measurement object groups are notified in order from "1" to "50" based on the specific information 90.

The notification in step ST7 is performed by receiving data 190 from the measuring device 12 in step ST10, and proceeding to the next step when a notification is received from the measuring device 12 that storage of the data 190 has been completed. As a result, when the terminal 14 is notified by the measuring device 12 that storage has been completed, it notifies the identifier 98 to be notified next.

In step SS24, the measuring device 12 determines whether the measurement is complete based on whether the measurement target number has reached the end number 114 (step SS24).

If it is determined in step SS24 that the measurement target number has reached the end number 114 and the measurement is complete, this process ends. Also, if it is determined in step SS24 that the measurement target number has not reached the end number 114 and the measurement is not complete, the process branches to step SS8 and reports the measurement target number.

As a result, when the data 190 including the saved data 198 and the identifier 98 last saved in the memory unit 32 is deleted, the identifier 98 associated with the deleted saved data 198 is notified (step SS8).

On the other hand, if the data 190 last stored in the memory unit 32 is not deleted, the identifier 98 indicated by the measurement object number counted up in step SS19 is notified (step SS8). As a result, the identifiers 98 of each of the measurement object groups are notified in order from "1" to "50" based on the specific information 90.

In addition, in step SS17, the stored data 198 acquired in step SS16 is stored in the memory unit 32 in association with the specific information 90 of the measurement object for which the measurement results were acquired. As a result, each time the identifier 98 of the measurement object is notified, the stored data 198 is stored in association with the notified identifier 98.

(Action and Effects)
Next, the effects of this embodiment will be described.

The measurement system 10 in this embodiment is a measurement system 10 configured so that a measuring device 12 and a terminal 14 can communicate with each other. The measuring device 12 includes a measurement unit 62 that executes a measurement process to measure a physical quantity of a measurement target, a detection unit 70 that detects the execution of the measurement process, and a transmission permission unit 72 that permits the transmission of measurement results to the terminal 14 when the detection unit 70 detects the execution of the measurement process. The terminal 14 includes a result receiving unit 84 that receives the measurement results from the measuring device 12, and an execution unit 86 that executes a predetermined process based on the received measurement results.

According to this configuration, the measuring device 12 is permitted to transmit the measurement results to the terminal 14 upon detecting the execution of a measurement process.

As a result, it is possible to suppress the reception and transmission processes that may occur during the measurement process, compared to a case in which request commands from the terminal 14 are constantly accepted and measurement results must be transmitted to the terminal 14 each time a request command is accepted.

This makes it possible to reduce the impact that may be caused to the measurement process.

In addition, in the measurement system 10 of this embodiment, the terminal 14 includes a transmitting unit 80 that transmits specific information 90 that identifies the measurement target to the measuring device 12. The measuring device 12 includes a receiving unit 60 that receives the specific information 90 from the terminal 14, and a storage unit 64 that stores stored data 198 based on the measurement results of the measurement of the physical quantity of the measurement target by the measuring unit 62 based on the received specific information 90, in association with the specific information 90.

According to this configuration, specific information 90 that identifies the measurement target can be transmitted from the terminal 14 to the measuring device 12. This eliminates the need to input the specific information 90 into the measuring device 12. Furthermore, compared to manually inputting the specific information 90 into the measuring device 12, it is possible to improve workability and reduce work time.

Before starting the measurement operation, for example, multiple pieces of specific information 90 can be registered together in the measuring device 12. This makes it possible to reduce input errors. In addition, by using the copy and paste function, for example, of the terminal 14, it is possible to further shorten the operation time.

In addition, since the stored data 198 based on the measurement results from the measuring device 12 is stored in association with the specific information 90, it is possible to understand the relationship between the stored data 198 and the specific information 90 from the stored data 190.

This makes the measurement process easier and improves convenience compared to when records must be kept for each measurement to match the measurement target with the measurement results.

In addition, the stored data 198 and the specific information 90 are stored in association with each other. Therefore, when creating a report after a measurement, there is no need to manually match the measurement results, which are an example of the stored data 198, with the measurement location, which is an example of the specific information 90.

In addition, there is no need to check the data after measurement. This not only shortens the time required for post-measurement work, but also prevents the need to redo measurements due to mismatching.

Furthermore, the work that previously required two people, a measurer and a recorder, can now be done by the measurer alone. This makes it possible to reduce the number of people required for measurement work.

Then, the stored data 198 etc. are stored in the measuring device 12. Therefore, compared to the case where the stored data 198 is transmitted and stored in the terminal 14, it is possible to prevent errors in storing data due to communication failures, and reliability is improved.

In this embodiment, the terminal 14 further includes a generation unit 82 that generates specific information 90. The specific information 90 includes subject group specific information 96 that identifies a measurement subject group having multiple measurement subjects, and management information 110 that identifies multiple identifiers 98 for managing each of the measurement subject groups. The storage unit 64 associates the subject group specific information 96 together with the identifiers 98 with each of the stored data 198 of the measurement subject group by the measurement unit 62 based on the specific information 90.

This configuration makes it possible to eliminate the need for cumbersome input work on the measuring device 12, compared to manually inputting the subject group identification information 96 that identifies the measurement subject group and the identifier 98 for managing each measurement subject group on the measuring device 12.

Furthermore, in this embodiment, the target group identification information 96 includes at least one of type information 106 indicating the type of the measurement target group and room information 102 for identifying the room that houses the measurement target group.

With this configuration, the type information 106 or room information 102 contained in the stored data 190 can be used to facilitate the creation of a post-measurement report.

In addition, in this embodiment, the specific information 90 is stored in multiple areas allocated to the memory of the measuring device 12, and the multiple identifiers 98 identified by the management information 110 are in one-to-one correspondence with the memory identifier 116 that identifies each area.

With this configuration, it is possible to obtain the identifier 98 identified by the management information 110 from the area indicated by the memory identifier 116.

Furthermore, in this embodiment, the measuring device 12 includes a notification unit 66 that notifies the identifier 98 of the measurement object in sequence. Each time the notification unit 66 notifies the identifier 98 of the measurement object, the storage unit 64 stores the saved data 198 in association with the notified identifier 98.

With this configuration, the person measuring the object to be measured can be guided based on the specific information 90 set in the measuring device 12.

As a result, the person taking the measurements does not need to look at documents or other documents that list the object being measured during the measurement. This makes it possible to reduce measurement errors and shorten the work time required for the measurement.

In particular, when there are many measurement targets, it is possible to prevent measurement errors such as skipping one measurement target or measuring the same measurement target twice.

The notification of the identifier 98 is also performed by the measuring device 12. Therefore, even if a wireless communication device such as a smartphone configured as a separate device from the measuring device 12 cannot be brought to the measurement location, the measuring device 12 can perform the notification on its own.

In addition, in this embodiment, the stored data 198 is determined based on the measurement results obtained within a predetermined period after the detection unit 70 detects that the measurement process is being performed.

This configuration makes it possible to store the stored data 198 with reduced influence of noise and other factors on the measured values, compared to when the measured values are used as the stored data 198.

Furthermore, in this embodiment, the measuring device 12 transmits the identifier 98 that the notification unit 66 will next notify to the terminal 14, and when the terminal 14 receives the identifier 98 from the measuring device 12, it notifies the terminal 14 of the received identifier 98.

With this configuration, the measurement subject can be guided to the person measuring from the terminal 14.

In addition, in this embodiment, the measuring device 12 notifies the terminal 14 of the end of storage when the storage process by the storage unit 64 is completed, and the terminal 14 notifies the terminal 14 of the identifier 98 to be notified next when the measuring device 12 notifies the terminal 14 of the end of storage.

According to this configuration, the next identifier 98 to be notified is notified after the saving process in the measuring device 12 is completed. This makes it possible to save data reliably while promoting the shortening of the measurement time, compared to a case in which the next identifier 98 to be notified is notified when the person taking the measurement has finished measuring the subject.

In addition, in this embodiment, the terminal 14 is configured to be portable by the person taking the measurement, and notifies the user of the identifier 98 of the measurement object by sound.

With this configuration, compared to when the identifier 98 of the measurement target is displayed, it is possible to concentrate on the measurement task without taking one's eyes off the measurement point. This reduces measurement errors and shortens the work time required for measurement.

The identifier 98 is notified by sound via a terminal 14 that can be carried by the person taking the measurement. For this reason, by storing the terminal 14 in a place closer to the ear than the measuring device 12, such as a breast pocket, it is possible to prevent mishearing of the identifier 98. In particular, by using a terminal 14 that has a volume adjustment function, it is possible to further prevent mishearing of the identifier 98.

In addition, in this embodiment, the measuring device 12 includes a deletion unit 68 that deletes the stored data 198 and identifier 98 last stored by the storage unit 64 in response to an operational input by the person measuring.

According to this configuration, if the measurement subject is incorrect, the person making the measurement can delete the last saved data 198 and identifier 98 by performing an operation input. In addition, by repeating the operation input, it is possible to return to the measurement start state.

This improves convenience compared to having to start the measurement over again from the first measurement target if a measurement error occurs.

This operation input is performed using the measuring device 12. Here, the person performing the measurement may wear gloves to prevent electric shock, etc., and it is easier to perform operation input using, for example, rubber keys provided on the measuring device 12 than using a mobile terminal such as a smartphone or a personal computer. Also, compared to when operation input is performed using a mobile terminal such as a smartphone or a personal computer, there is no need to take off the gloves, which makes it possible to shorten the measurement time.

In addition, in this embodiment, when the deletion unit 68 performs deletion, the notification unit 66 notifies the identifier 98 associated with the deleted stored data 198.

According to this configuration, when the last saved data 198 and identifier 98 are deleted, the identifier 98 associated with the deleted saved data 198 is notified. This makes it possible to prevent mistakes in measuring the target.
