Description

  The present invention includes a measurement device configured to include a communication unit that receives control data transmitted from an external device and transmits transmission data to the external device, and a measurement device and a mobile terminal device as the external device. The present invention relates to a measurement system configured as described above.

  For example, Japanese Unexamined Patent Application Publication No. 2011-176530 discloses a remote operation system configured to be able to remotely operate an OTDR (optical pulse tester) using a mobile phone. In using this remote control system, first, the OTDR and the mobile phone are wirelessly connected to each other. At this time, when a wireless connection is established between the OTDR and the mobile phone (when communication is possible), an initialization command is transmitted from the mobile phone to the OTDR to initialize the OTDR. Next, the mobile phone is operated to transmit measurement condition data and a measurement start command to the OTDR. In response to this, in OTDR, measurement processing is executed according to the transmitted measurement conditions. The OTDR transmits state information indicating the state of the OTDR at that time to the mobile phone. At this time, on the mobile phone, for example, a message “Measuring Now...” Is displayed on the display unit based on the transmitted state information.

  Further, in the mobile phone, the measurement data request unit determines whether or not the measurement process by OTDR is completed based on the state information transmitted from OTDR. Send. In response to this, waveform data is transmitted from the OTDR to the mobile phone, and a waveform based on the transmitted waveform data is displayed on the display unit of the mobile phone. In addition, the above-mentioned publication discloses an example in which a result of measurement processing by OTDR is displayed in real time on a display unit of a mobile phone. Specifically, in this example, the mobile phone transmits a data request after transmitting a measurement start command to the OTDR and a waveform display process based on the waveform data transmitted from the OTDR at regular time intervals. Run alternately. As a result, the measurement results displayed on the display unit of the mobile phone are updated at regular time intervals.

It is configured. In addition, since the component for implement | achieving "the function as a mobile telephone" in the smart phone 2 or the "function as PDA" is well-known, illustration and description are abbreviate | omitted. The main body memory 21 stores an operation program of the smartphone 2 and stores various programs (programs installed by the user) such as the measurement system program Dp. A part of the program such as the measurement system program Dp can be installed in the storage memory M mounted in the storage memory mounting unit 27.

  The operation unit 22 includes a touch panel disposed on the surface side of the display unit 23 in addition to a power switch (not shown) and outputs operation signals corresponding to these operations to the control unit 26. The display unit 23 is an example of a “display unit of a mobile terminal device”, and displays various display screens under the control of the control unit 26. In this case, in this measurement system 100, when the measurement system program Dp is executed in the smartphone 2 as will be described later, the same layout as the measurement processing screen 30a displayed on the display unit 13 of the measurement apparatus 1 is used. A configuration is adopted in which a monitor display area 41 (see FIG. 2) showing the same information as the measurement processing screen 30a is displayed on the measurement processing screen 30b (see FIG. 2) in the display unit 23 of the smartphone 2. Further, in the smartphone 2 of this example, in addition to the monitor display area 41 described above, display is performed on the main body memory 21 or the storage memory M mounted on the storage memory mounting unit 27 by the operation of the touch panel on the operation unit 22. A configuration is adopted in which an operation switch display area 42 for storing the data D1 (storing the display data D1) is displayed in the measurement processing screen 30b.

  The wireless communication unit 24 is configured to be able to execute short-range wireless communication in accordance with the Bluetooth standard in the same manner as the wireless communication unit 14 of the measurement apparatus 1. As will be described later, the wireless communication unit 24 transmits control data D0 to the measurement device 1 according to the control of the control unit 26 in a state of being paired with the measurement device 1, and is transmitted from the measurement device 1. The display data D1 received is output to the control unit 26. Similarly to the wired communication unit 15 of the measurement apparatus 1, the wired communication unit 25 includes a connection connector conforming to the USB standard, and the measurement apparatus via a signal cable C (see FIG. 1) connected to the connection connector. 1 and various external devices (not shown) are connectable. The wired communication unit 25 transmits the control data D0 to the measuring device 1 according to the control of the control unit 26 in a state where the wired communication unit 25 is connected to the measuring device 1 via the signal cable C, and also displays the display data transmitted from the measuring device 1. The data D1 is received and output to the control unit 26.

  The control unit 26 controls the smartphone 2 as a whole. Specifically, when the control unit 26 is instructed to execute the measurement system program Dp by operating the operation unit 22, the control unit 26 displays the measurement processing screen 30 b on the display unit 23, and the wireless communication unit 24 or wired The communication unit 25 is controlled to execute transmission processing for periodically transmitting the control data D0 for requesting the start of transmission of the display data D1 to the measuring apparatus 1 at a preset cycle. In addition, the control unit 26 displays the monitor display area 41 in the measurement processing screen 30b based on the display data D1 received via the wireless communication unit 24 or the wired communication unit 25. Further, when the control unit 26 is instructed to save the display data D1 by the operation of the operation unit 22, the control unit 26 displays it on one of the main body memory 21 and the storage memory M in accordance with the measurement system program Dp. Data D1 is stored.

  In using the measurement system 100, first, the measurement system program Dp is installed in the smartphone 2. As an example of the measurement system program Dp, an installation optical disk can be provided as an accessory of the measurement apparatus 1, or can be downloaded from an arbitrary site on the Internet and used. Note that the installation work of the measurement system program Dp is the same as the installation work of various programs for an existing general smartphone, and thus detailed description thereof is omitted. Next, Bluetooth pairing is performed between the measuring apparatus 1 (wireless communication unit 14) and the smartphone 2 (wireless communication unit 24). Since the pairing work is the same as the pairing work of various known Bluetooth devices, detailed description is omitted. Thereby, the measurement system 100 is ready for use.

  On the other hand, in order to perform the measurement process on the measurement object using the measurement system 100, as an example, the operation unit 12 of the measurement apparatus 1 is controlled to set the measurement process conditions, and the measurement is performed by the clamp sensor unit 11a. Clamp the object. Next, when the start switch of the operation unit 12 is operated, the control unit 16 controls the measurement unit 11 according to the set measurement conditions to start the measurement process, and the measurement unit 11 is clamped by the clamp sensor unit 11a. The measured ground resistance of the measurement target is measured, and measurement data Ds (measurement value) is output to the control unit 16. The control unit 16 stores the measurement data Ds output from the measurement unit 11 in the memory 17 and generates display data D1 based on the stored measurement data Ds and the operation state of the measurement apparatus 1. Further, the control unit 16 generates display data based on the measurement data Ds and the operation state of the measurement apparatus 1 and outputs the display data to the display unit 13. Thereby, as shown in FIG. 2, the measurement result display 31 indicating the ground resistance of the measurement object is displayed on the measurement processing screen 30 a of the display unit 13.

  On the other hand, when displaying the measurement result by the measurement device 1 and the operation state of the measurement device 1 on the display unit 23 of the smartphone 2, the operation unit 12 of the measurement device 1 is controlled to start the operation of the wireless communication unit 14. The operation of the wireless communication unit 24 is started by operating the operation unit 22 of the smartphone 2. At this time, a state in which wireless connection is established between the measuring device 1 (wireless communication unit 14) and the smartphone 2 (wireless communication unit 24) paired by the above-described pairing work and can communicate with each other. Become. Next, the operation unit 22 is operated to start the measurement system program Dp. At this time, the control unit 26 controls the display unit 23 to display the measurement processing screen 30b on the display unit 23 according to the measurement system program Dp, and controls the wireless communication unit 24 to control the measurement apparatus 1. Then, the transmission process of the control data D0 requesting the transmission start of the display data D1 is started. The execution order of the above operation for starting the operation of the wireless communication unit 24 and the above operation for starting the measurement system program Dp is not limited to this, and the wireless communication unit is started after the measurement system program Dp is started. The operation 24 (control data D0 transmission process) may be started.

  Further, in the measuring apparatus 1, when the control data D0 is received by the wireless communication unit 14, the control unit 16 controls the control data reception flag defined in the memory 17 to be in an on state. Next, the control unit 16 causes the wireless communication unit 14 to transmit the display data D1 requested to be transmitted by the control data D0 to the smartphone 2. In addition, the control unit 16 controls the control data reception flag to be in an ON state (that is, after receiving the control data D0 from the smartphone 2), and then a predetermined time (as an example, 0.5 seconds) Is passed (an example of “when a predetermined condition is satisfied”), the control data reception flag is controlled to be in an OFF state. In this example, the control data reception flag is turned off when a predetermined time elapses after the control data reception flag is turned on in response to reception of the control data D0 by the wireless communication unit 14. A series of processes until control is equivalent to the “first process”. Moreover, in this measuring apparatus 1, the control part 16 performs this "1st process" whenever control data D0 is transmitted from the smart phone 2. FIG.

  On the other hand, in the smartphone 2, when the display data D <b> 1 is received by the wireless communication unit 24, the control unit 26 controls the display unit 23 so that the measurement result and the operation state of the measurement apparatus 1 are within the monitor display area 41. Is displayed. As a result, for example, as shown in FIG. 2, the measurement processing screen in which the measurement result display 31 and the like are displayed in the monitor display area 41 in the same manner as the measurement processing screen 30a displayed on the display unit 13 of the measuring apparatus 1 is displayed. 30 b is displayed on the display unit 23 of the smartphone 2. Thereafter, as an example, the control unit 26 requests the transmission of the next display data D1 when 0.5 seconds have elapsed since the previous transmission of the display data D1 (request for the display data D1). Data D0 is transmitted from the wireless communication unit 24, and the monitor display area 41 in the measurement processing screen 30b is updated based on the display data D1 transmitted from the measuring apparatus 1 in response to the data D0. Thereby, in the monitor display area 41 of the measurement processing screen 30 b displayed on the display unit 23 of the smartphone 2, the same information as the measurement processing screen 30 a displayed on the display unit 13 of the measurement apparatus 1 is 0. Updated and displayed every 5 seconds.

  In this case, in the measuring device 1 in the measuring system 100, as described above, the control unit 16 is shown in FIG. 4 in a state where the measuring device 1 is turned on (the measuring device 1 is operating). A configuration for executing the mark display processing 50 is employed. In the mark display process 50, the control unit 16 monitors whether or not an instruction to start the operation of the wireless communication unit 14 is made by operating the operation unit 12 (step 51). When instructed to start the operation, the control unit 16 controls the power supply unit (not shown) to supply power to the wireless communication unit 14 to start the operation of the wireless communication unit 14 as described above. In addition, as shown in FIG. 5, the display unit 13 is controlled to display the operating mark 34 in the measurement processing screen 30a (step 52).

  Next, the control unit 16 determines whether or not an instruction to stop the operation of the wireless communication unit 14 is made by operating the operation unit 12 (step 53). At this time, for example, when instructed to stop the operation immediately after the instruction to start the operation of the wireless communication unit 14, the control unit 16 controls the display unit 13 as shown in FIG. After the operating mark 34 displayed in the display screen 30a is hidden (step 54), it is monitored again whether or not an instruction to start the operation is given (step 51). On the other hand, when it is determined in step 53 that the operation is not instructed to stop, the control unit 16 determines whether or not the control data reception flag is in the ON state (step 55).

  At this time, when it is determined that the control data reception flag is in the ON state, the control unit 16 determines whether or not the operating mark 34 is displayed on the display unit 13 (step 56). Further, when the control unit 16 determines that the operating mark 34 is displayed, the control unit 16 controls the display unit 13 to hide the operating mark 34 (step 57), and then proceeds to step 53 described above. At the same time, when it is determined that the operating mark 34 is not displayed, the display unit 13 is controlled to display the operating mark 34 (step 58), and then the process returns to step 53 described above. On the other hand, when it is determined in step 55 that the control data reception flag is off, the control unit 16 controls the display unit 13 to display the operating mark 34 when the operating mark 34 is not displayed. When the operating mark 34 is displayed, the display unit 13 is controlled to continue displaying the operating mark 34 (step 58), and the process returns to step 53.

  In this case, in this example, the series of processes in steps 55 to 58 corresponds to the “mark display state switching process” as the “second process”, and the measurement apparatus 1 is powered on. In parallel with the “first process” described above, this “second process” is repeatedly executed. Further, in the measuring apparatus 1 of the present example, after determining the state of the control data reception flag in step 55, the process of steps 56, 57 and step 53, or the processes of steps 56, 58 and step 53 is performed again. For example, the time until the above determination is executed (the time interval for executing the determination process in step 55: an example of “predetermined time interval”) is specified to be about 0.5 seconds as an example. Further, in the measurement apparatus 1, as described above, the control unit 16 controls the control data reception flag to be on when the wireless communication unit 14 receives the control data D0, and turns on the control data reception flag. A configuration is adopted in which the control data reception flag is controlled to be in an off state when a predetermined time (in this example, 0.5 seconds) has elapsed since the control to the state. Moreover, in the measurement system 100 of this example, the smartphone 2 transmits the control data D0 for requesting the measurement device 1 to transmit the display data D1 at intervals of 0.5 seconds.

  Therefore, in this example, the control data D0 is periodically transmitted from the smartphone 2 to the measurement device 1 with a period of 0.5 seconds, and the control data D0 is normally received by the measurement device 1 (wireless communication unit 14). While the measurement device 1 of the measurement device 1 is periodically executing the process of receiving data from the smartphone 2 (an example of “communication state”), the control data reception flag is on in the measurement device 1 Maintained in a state. For this reason, when it is determined in step 55 that is executed that the control data reception flag is on, it is determined in step 56 that the operating mark 34 is displayed, and then in step 57 the operating mark is displayed. 34 is not displayed, and it is determined that the control data reception flag is in the ON state in step 55 to be executed next, and after it is determined in step 56 that the operating mark 34 is not displayed, the operation is performed in step 58. The intermediate mark 34 is displayed, and thereafter, the processes of steps 53, 55, 56, and 57 and the processes of steps 53, 55, 56, and 58 are executed alternately.

  Thus, as long as the control data reception flag is controlled to be in the ON state (that is, as long as the measuring device 1 is in communication with the smartphone 2), the operating mark 34 is “predetermined time interval (0 in this example). .5 second intervals) ", the display state / non-display state are alternately switched (the operating mark 34 blinks at a constant cycle of 0.5 seconds). Accordingly, in the “communication state” in which the wireless communication unit 14 communicates with the smartphone 2 (wireless communication unit 24) with respect to the operator who has seen the operating mark 34 blinking on the display unit 13 (measurement processing screen 30a). It can be recognized (an example of “notification of communication state”).

  In this case, when notifying that the “communication state” is indicated by blinking the operating mark 34, for example, when the time during which the operating mark 34 is displayed is shorter than the time during which the operating mark 34 is not displayed. May be difficult to recognize the operating mark 34. Conversely, when the operating mark 34 is displayed longer than the non-displaying time, the operating mark 34 is turned on. May be mistakenly recognized. On the other hand, while the control data reception flag is controlled to be in the ON state, the state where the operating mark 34 is displayed and the state where it is not displayed are repeated at a constant cycle (in this example, a cycle of 0.5 seconds). Thus, in the measuring apparatus 1 of this example in which the time during which the operating mark 34 is displayed and the time during which the operating mark 34 is not displayed are equal to each other (0.5 seconds in this example), the operating mark It is possible to reliably recognize that 34 is blinking and displayed.

  On the other hand, when one of the measurement device 1 and the smartphone 2 is too far from the other and the control device D0 (wireless communication unit 14) cannot normally receive the control data D0 transmitted from the smartphone 2, the control data D0, etc. When noise that is difficult to normally receive is generated, or when the smartphone 2 stops transmission of the control data D0 (transmission request for display data D1) (an example of “non-communication state”, respectively) The control data reception flag is controlled to be in an OFF state when 0.5 seconds have elapsed from the time when the data D0 is normally received, and thereafter, until the control data D0 from the smartphone 2 is normally received (“communication state”). ”Until the control data reception flag is kept off. For this reason, it is specified in step 55 that the control data reception flag is in the OFF state, the operating mark 34 is displayed in step 58 (display of the operating mark 34 is continued), and also in step 55 executed thereafter. The control data reception flag is identified as being in the OFF state, and the state in which the operating mark 34 is displayed in step 58 is continued.

  Thus, as long as the control data reception flag is controlled to be in the off state (that is, as long as the measuring device 1 is not in communication with the smartphone 2), the display of the operating mark 34 is continued (the operating mark 34 is The lighted state is maintained). Therefore, the wireless communication unit 14 is not communicating with the smartphone 2 (wireless communication unit 24) with respect to an operator who sees the operating mark 34 that continues to light without blinking on the display unit 13 (measurement processing screen 30a). It can be recognized that it is “non-communication state” (an example of “notification of non-communication state”). When the display data D1 is transmitted from the smartphone 2 to the measurement device 1 except when the transmission of the display data D1 from the smartphone 2 is stopped, the distance between the measurement device 1 and the smartphone 2 is communicated. When the measuring apparatus 1 (wireless communication unit 14) normally receives the display data D1 because it falls within the possible distance range or does not generate noise, the control data reception flag is controlled to be on. As a result, as described above, the operating mark 34 is blinked on the display unit 13 (measurement processing screen 30a). Thereby, it can be made to recognize that the radio | wireless communication part 14 became the "communication state" again with the smart phone 2 (wireless communication part 24) (another example of "notification of being in a communication state").

  In this case, by changing the display mode (in this example, blinking or lighting) of the operating mark 34 depending on whether the wireless communication unit 14 is in “communication state” or “non-communication state”, the “communication state” ”Or“ non-communication state ”, for example, a message“ communication ”is displayed on the display unit 13 in the“ communication state ”, and the“ non-communication state ”is displayed. Sometimes, by displaying a message “communication stopped”, it is possible to notify whether the communication state or the non-communication state. However, even when such a configuration is adopted, it is necessary to display an operating mark 34 for notifying whether or not the wireless communication unit 14 is operating on the display unit 13 separately from the above message. For this reason, the display screen is crowded, and the visibility of the measurement result display 31 or the like may be reduced. However, in this measurement apparatus 1, the “communication state” and the “non-communication state” are switched by switching the display mode of the in-operation mark 34 for notifying whether or not the wireless communication unit 14 is in operation. Therefore, it is possible to reliably and easily visually recognize the measurement result display 31 and the like without occupying a valuable display area of the display unit 13 with information for notifying this.

  As described above, in the measurement apparatus 1, the control unit 16 controls the control data flag to the ON state when the control data D0 from the smartphone 2 is received by the wireless communication unit 14, and the requested display data D1. Is transmitted from the wireless communication unit 14 to the smartphone 2, and the “first process” is performed to control the control data flag to the off state when the “predetermined condition” is satisfied in the state where the control data flag is controlled to the on state. ”Indicating that the control data flag is in an on state or an off state at a predetermined time interval, and when the control data flag is identified as being in an on state, the wireless communication unit 14 is in“ communication state ” In parallel with the "second process" in which the wireless communication unit 14 notifies that the wireless communication unit 14 is in the "non-communication state". . In addition, the measurement system 100 includes the measurement device 1 described above and a smartphone 2 corresponding to a “portable terminal device” as an “external device”, and displays the measurement result of the physical quantity by the measurement device 1 on the display unit 23 of the smartphone 2. It is configured so that it can be displayed.

  Therefore, according to the measurement device 1 and the measurement system 100, it is possible to reliably and easily specify whether or not the communication with the smartphone 2 is possible, and the measurement device 1 (wireless communication unit 14) receives nothing. When it is informed that it is in “communication state”, it can be specified that nothing is transmitted from the smartphone 2, and it is informed that it is in “non-communication state”. Sometimes, even if some data is transmitted from the smartphone 2, it can be specified that the data may not be received.

  In the measurement apparatus 1 and the measurement system 100, when the control unit 16 starts the operation of the wireless communication unit 14, the control unit 16 controls the display unit 13 to display the operating mark 34, As processing, when the control data reception flag is on and the operation mark 34 is displayed, the operation mark 34 is hidden, the control data reception flag is on and the operation mark 34 is in operation. When the operation mark 34 is not displayed, the operation mark 34 is displayed. When the control data reception flag is OFF and the operation mark 34 is displayed, the operation mark 34 is continuously displayed. When the control data reception flag is off and the operating mark 34 is not displayed, “mark display state switching processing” is executed to display the operating mark 34 That.

  Therefore, according to the measurement apparatus 1 and the measurement system 100, not only can the radio communication unit 14 be surely and easily identified and notified whether the wireless communication unit 14 is in the “communication state” or the “non-communication state”, Based on the display state of a mark separate from the operating mark 34 and the lighting state of an indicator separate from the various marks displayed on the display unit 13 (measurement processing screen 30a), the wireless communication unit 14 is “communication state”. And a mark for notifying whether the valuable display area of the display unit 13 is “communication state” or “non-communication state”, unlike the configuration for notifying whether it is “non-communication state”. The visibility of the measurement result display 31 is reduced, or the manufacturing cost increases due to the provision of components (indicators, etc.) other than the display unit 13. Without causing a situation, whether it is ready to communicate with the smart phone 2 can be reliably and easily identified.

  Furthermore, according to the measurement apparatus 1 and the measurement system 100, the control unit 16 receives a control data D0 in the “first process”, and is a predetermined time (in this example, 0.5 seconds). By determining that the “predetermined condition” is satisfied when the time elapses and controlling the control data flag to the OFF state, the measuring device 1 (wireless communication unit 14) is in the “non-communication state” with the smartphone 2. When this happens, the control data reception flag can be reliably controlled to be in the off state, and the “non-communication state” can be reliably notified.

Contact name By switching the display mode of the work Dochu mark 34, the measuring apparatus 1 having the configuration measuring apparatus 1 (the wireless communication unit 14) for notifying which of "communication state" and "non-communicating state" Although described as an example, instead of this configuration, a configuration for informing which of the “communication state” and the “non-communication state” by switching the display mode of a notification-only mark (not shown), A configuration for notifying the “communication state” or “non-communication state” by switching the display mode of a dedicated indicator provided separately from the display unit 13, and “communication state” and “non-communication” by voice It is also possible to adopt a configuration for informing which of the “state”. Even when such a configuration is adopted, the same effects as those of the measurement apparatus 1 can be obtained.

  In addition, as an example of a state “when a pre-defined condition is satisfied”, “when a predetermined time has elapsed since the control data reception flag was controlled to be on (in the above example, the smartphone 2 The measurement apparatus 1 configured to control the control data reception flag to the off state is described as an example when “the same 0.5 second as the transmission interval of the control data D0 from” has elapsed). The “time” does not have to be the same time as the transmission interval of the control data D0 from the smartphone 2, and can be any time that is equal to or less than the transmission interval of the control data D0. In addition, the “predetermined condition” is not limited to “when a predetermined time has elapsed”. For example, “the display data D1 from the wireless communication unit 14 to the smartphone 2 (wireless communication unit 24)” A configuration may be employed in which the control data reception flag is controlled to be turned off when the transmission is completed. Even when such a configuration is adopted, the same effects as those of the measurement apparatus 1 can be obtained.

  Further, the measurement system 100 including the measurement apparatus 1 having the wireless communication unit 14 capable of performing short-range wireless communication in accordance with the Bluetooth standard has been described as an example. However, instead of this configuration, or in this configuration, In addition, a “communication unit” includes a wireless communication unit (not shown) capable of performing wireless communication in accordance with various wireless communication standards such as various wireless LAN standards, ZigBee (registered trademark) standards, and IrDA standards. A “measuring system” can also be configured with a “measuring device”. Even when such a configuration is adopted, the same effect as the above-described measurement apparatus 1 and the measurement system 100 including the measurement apparatus 1 can be obtained by executing the same process as the mark display process 50 described above. Can do. Further, the measurement apparatus 1 configured to notify either “communication state” or “non-communication state” regarding the wireless communication by the wireless communication unit 14 has been described, but instead of such a configuration (or such a configuration) In addition, it is also possible to employ a configuration for notifying either “communication state” or “non-communication state” regarding wired communication by the wired communication unit 15.

  Moreover, although the example which transmits the display data D1 from the measuring apparatus 1 to the smartphone 2 as “transmission data” has been described, the measurement data itself is used as “transmission data” instead of the display data D1 from the measurement apparatus 1. A configuration for transmitting to the smartphone 2 can also be adopted. Furthermore, although the measurement system 100 including the smartphone 2 as an example of the “portable information terminal” as the “external device” has been described as an example, the “external device (portable information terminal)” is not limited to the smartphone. As long as the device can communicate with the “communication unit of the measurement device”, for example, a general-purpose device such as a mobile phone or a personal computer and an electronic device dedicated to the measurement system can be used instead of the smartphone 2. In addition, the configuration including the measurement device 1 that is a clamp-type resistance measurement device has been described as an example, but the configuration of the “measurement device” is not limited thereto, and the current value, voltage value, resistance value, power value, A configuration for measuring various “physical quantities” such as phase, temperature, humidity, luminance (luminous intensity), illuminance, rainfall, and flow rate can be employed.
