MODE FOR CARRYING OUT THE INVENTION

[0011] (This Embodiment) (1) Outline Hereinafter, the outline of the measurement system 100 according to this embodiment will be described with reference to FIGS. 1 and 2.

[0012] The measurement system 100 according to this embodiment is a system for measuring the amount of the stored material Y2 (see FIG. 2) stored in the silo Y1. The silo Y1 is a tower-shaped warehouse for storing the stored material Y2 in a bulk state. For example, the stored material Y2 is a granular material such as cement, feed, and fertilizer.

[0013] As shown in FIG. 1, the measurement system 100 of the present embodiment includes a measurement unit 11, a first communication unit 21, a second communication unit 31, and a presentation unit 41. The measurement unit 11 measures a physical quantity related to the amount of the contained substance Y2 contained in the silo Y1. The first communication unit 21 is connected to the measurement unit 11 and wirelessly transmits the measurement result of the measurement unit 11 output from the measurement unit 11. The second communication unit 31 receives the measurement result of the measurement unit 11 transmitted from the first communication unit 21. The presentation unit 41 presents the measurement result of the measurement unit 11 received by the second communication unit 31.

[0014] From the above, in the measurement system 100 of the present embodiment, when a user uses the measurement system 100 to check the measurement result of the measurement unit 11, there is no need to move to the location where the measurement unit 11 is installed, and the user can check the measurement result of the measurement unit 11 presented by the presentation unit 41 at the location where the presentation unit 41 is provided. In short, the measurement system 100 of the present embodiment has the advantage of being able to improve the usability when checking the measurement result of the measurement unit 11.

[0015] (2) Detailed configuration (2-1) Measurement system Hereinafter, the detailed configuration of the measurement system 100 of the present embodiment will be described with reference to FIGS. 1 to 9.

[0016] As shown in FIG. 1, the measurement system 100 of the present embodiment includes a plurality (four) of measurement devices 1, a driver 2, a controller 3, and a display device 4. That is, in the measurement system 100 of the present embodiment, there are a plurality of measurement devices 1.

[0017] (2-2) Measurement device Each of the four measurement devices 1 is a device that measures a physical quantity related to the amount of the contained substance Y2 (see FIG. 2) contained in the silo Y1. In the present embodiment, each of the four measurement devices 1 is installed in a different silo Y1. That is, each of the four measurement devices 1 is a device that measures the physical quantity of the contained substance Y2 contained in a different silo Y1.

[0018] Each of the four measuring devices 1 includes a housing 10, a measuring unit 11, and a drive control unit 12. The housing 10 houses the measuring unit 11 and the drive control unit 12. The housing 10 is formed of a metal material.

[0019] The measuring unit 11 measures a physical quantity related to the amount of the stored material Y2 (see FIG. 2) stored in the silo Y1. In the present embodiment, the measuring unit 11 measures, as a physical quantity related to the amount of the stored material Y2, the internal empty height H1 (see FIG. 2) in the silo Y1 where the stored material Y2 is not stored. Specifically, the measuring unit 11 is a measuring mechanism configured to be able to measure the internal empty height H1. Note that the "internal empty height H1" referred to in the present disclosure is the distance from the top plate of the silo Y1 to the upper surface of the stored material Y2 (i.e., the value obtained by subtracting the remaining amount height H2 where the stored material Y2 is stored from the vertical dimension of the silo Y1). Hereinafter, the "physical quantity related to the amount of the stored material Y2" may also be referred to as the "physical quantity of the stored material Y2".

[0020] In the present embodiment, since each of the four measuring devices 1 is installed in a different silo Y1, the measuring unit 11 in each of the four measuring devices 1 measures the physical quantity of the stored material Y2 stored in a different silo Y1. Specifically, the measuring unit 11 in each of the four measuring devices 1 measures the internal empty height H1 of the stored material Y2 stored in a different silo Y1 as the physical quantity of the stored material Y2.

[0021] As shown in FIG. 3, the measuring unit 11 of the present embodiment includes a tape 111, a winding drum 112, a detection drum 113, a turn drum 114, a weight 115, and a turn lever 116. The measuring unit 11 of the present embodiment obtains the internal empty height H1 in the silo Y1 where the stored material Y2 is not stored by measuring the distance from the bottom surface of the weight 115 to the upper surface of the stored material Y2 stored in the silo Y1. Note that FIG. 3 is a simplified diagram for explaining the schematic mechanism (e.g., positional relationship or interlocking relationship, etc.) of the measuring unit 11, and does not limit the actual configuration of the measuring unit 11.

[0022] The take-up drum 112 and the detection drum 113 are rotatably provided on the housing 10. Specifically, the take-up drum 112 and the detection drum 113 are provided on the housing 10 side by side in the left-right direction. The turn drum 114 is provided on the housing 10 so as to be movable in the vertical direction via a turn lever 116 in a state of being biased upward by a spring force below the detection drum 113. A part of the tape 111 is wound around the take-up drum 112. On the other hand, the portion of the tape 111 that is not wound around the take-up drum 112 is sequentially passed around the detection drum 113 and the turn drum 114, and a weight 115 is attached to the tip thereof. The turn drum 114 is normally moved downward against the spring force by the weight of the weight 115 attached to the tip of the tape 111.

[0023] The drive control unit 12 drives the measurement unit 11 and causes the measurement unit 11 to measure the physical quantity of the stored material Y2. In the present embodiment, the drive control unit 12 rotates the take-up drum 112 of the measurement unit 11. More specifically, when a start control signal is input from a measurement control unit 22 (to be described later) of the driver 2, the drive control unit 12 rotates the take-up drum 112 in the forward direction (counterclockwise direction shown in FIG. 3).

[0024] When the take-up drum 112 rotates in the forward direction, the winding of the tape 111 is gradually released, and the weight 115 attached to the tip of the tape 111 gradually hangs down into the silo Y1. As the weight 115 gradually hangs down into the silo Y1, the detection drum 113 around which the tape 111 is passed rotates. When the weight 115 gradually hangs down into the silo Y1 and reaches the upper surface of the stored material Y2 stored in the silo Y1 (when the weight 115 hangs down to the position shown by the two-dot chain line in FIG. 2), the weight of the weight 115 is received by the stored material Y2, and the turn drum 114 around which the tape 111 is passed moves upward by the spring force. The drive control unit 12 detects that the turn drum 114 has moved upward and stops the forward rotation of the take-up drum 112.

[0025] The measuring unit 11 further includes an encoder (not shown) that detects the rotation speed of the detection drum 113. The measuring unit 11 measures, as the physical quantity of the stored material Y2, the hanging length of the tape 111, that is, the internal empty height H1 of the silo Y1, from the rotation speed of the detection drum 113 detected by the encoder during the period from when the drive control unit 12 rotates the take-up drum 112 until it stops the rotation of the take-up drum 112. The measuring unit 11 transmits the measured physical quantity of the stored material Y2 to the first communication unit 21 of the driver 2, which will be described later. In short, the measuring unit 11 transmits the measured internal empty height H1 of the silo Y1 to the first communication unit 21 of the driver 2 as the physical quantity of the stored material Y2.

[0026] After stopping the forward rotation of the take-up drum 112, the drive control unit 12 rotates the take-up drum 112 in the reverse direction (clockwise as shown in Fig. 3). When the take-up drum 112 rotates in the reverse direction, the tape 111 is gradually rewound, and the weight 115 is gradually lifted inside the silo Y1. As the weight 115 is gradually lifted inside the silo Y1, the detection drum 113 around which the tape 111 is stretched rotates. When the weight 115 is lifted to a preset position, the drive control unit 12 stops the reverse rotation of the take-up drum 112.

[0027] In this embodiment, each of the four measuring devices 1 further includes an operation unit (not shown) that receives an operation of the user to drive or stop the measuring unit 11 by the drive control unit 12. According to this configuration, even when a start control signal is not input from the measurement control unit 22 of the driver 2 (that is, when a start control signal is not transmitted from the third communication unit 45 of the display device 4 described later), the user can drive or stop the measuring unit 11 by the drive control unit 12 by operating the above operation unit. As an example, when setting or maintaining the measuring unit 11, the user can drive or stop the measuring unit 11 by the drive control unit 12 by operating the above operation unit. More specifically, each of the four measuring devices 1 has two operation units. One of the two operation units receives an operation of the user to drive the measuring unit 11 by the drive control unit 12, and the remaining operation unit receives an operation of the user to stop the measuring unit 11 by the drive control unit 12. When an abnormality is determined by the abnormality determination unit 482 described later, the operation unit does not receive an operation of the user.

[0028] (2-3) Driver The driver 2 controls each of the plurality of measuring devices 1. More specifically, the driver 2 controls whether the measuring unit 11 in each of the plurality of measuring devices 1 measures the physical quantity of the contained material Y2. The driver 2 is provided at a position closer to the silo Y1 where each of the plurality of measuring devices 1 is installed than the position where the controller 3 is provided. In the present disclosure, it is assumed that the driver 2 is provided outdoors near the silo Y1 where each of the plurality of measuring devices 1 is installed. That is, the driver 2 is an outdoor control panel of the silo Y1 where each of the plurality of measuring devices 1 is installed.

[0029] As shown in FIG. 1, the driver 2 includes a housing 20, a first communication unit 21, a measurement control unit 22, and a power supply unit 23. The housing 20 houses the first communication unit 21, the measurement control unit 22, and the power supply unit 23. The housing 20 is formed of a resin material.

[0030] The first communication unit 21 is connected to each of the plurality of measurement devices 1. In this embodiment, the driver 2 is wired-connected to each of the plurality of measurement devices 1. More specifically, the first communication unit 21 is wired-connected to the measurement unit 11 and the drive control unit 12 in each of the plurality of measurement devices 1.

[0031] In addition, the first communication unit 21 is configured to be capable of wireless communication with a second communication unit 31 (to be described later) of the controller 3. The communication method between the first communication unit 21 and the second communication unit 31 is wireless communication using radio waves, for example, in accordance with a communication standard such as a specific low-power radio station (a radio station that does not require a license) in the 920 MHz band.

[0032] The measurement control unit 22 controls whether the measurement unit 11 in each of the plurality of measurement devices 1 measures the physical quantity of the contained substance Y2. When the measurement control unit 22 receives a start operation signal (to be described later) from the second communication unit 31 of the controller 3 via the first communication unit 21, the measurement control unit 22 outputs a start control signal for causing the drive control unit 12 to measure the physical quantity of the contained substance Y2 by the measurement unit 11 to the drive control unit 12 in the measurement device 1 selected by the user's operation.

[0033] The first communication unit 21 outputs the measurement result of the measurement unit 11 from the measurement unit 11 (hereinafter also referred to as the "selected measurement unit 11") selected by the user's operation. That is, the first communication unit 21 outputs a physical quantity (the internal empty height H1 of the silo Y1) related to the amount of the contained substance Y2 contained in the silo Y1 measured by the measurement unit 11 from the selected measurement unit 11. The first communication unit 21 transmits the measurement result output from the selected measurement unit 11 (that is, measured by the selected measurement unit 11) to the second communication unit 31 of the controller 3 by wireless communication. That is, the first communication unit 21 transmits, by wireless communication, a physical quantity (the internal empty height H1 of the silo Y1) related to the amount of the contained substance Y2 contained in the silo Y1 measured by the selected measurement unit 11 to the second communication unit 31.

[0034] The power supply unit 23 is electrically connected to each of the external power supply P1 and the plurality of measurement devices 1. The external power supply P1 is, for example, an AC power supply of 100V or 200V. The power supply unit 23 converts the AC power supplied from the external power supply P1 into DC power and outputs it to each of the plurality of measurement devices 1.

[0035] (2-4) Controller The controller 3 is a device that relays communication between the driver 2 and the display device 4. The controller 3 is provided at a position farther from the silo Y1 where each of the plurality of measurement devices 1 is installed than the position where the driver 2 is provided. In the present disclosure, it is assumed that the controller 3 is provided indoors in a facility (such as an office or a rest room) where a user who uses the measurement system 100 stays for a long time. That is, the controller 3 is an indoor control panel of the silo Y1 where each of the plurality of measurement devices 1 is installed.

[0036] The controller 3 includes a housing 30 and a second communication unit 31. The housing 30 houses the second communication unit 31. The housing 30 is formed of a resin material.

[0037] The second communication unit 31 is configured to be capable of wireless communication with the first communication unit 21 of the driver 2. The communication method between the first communication unit 21 and the second communication unit 31 is wireless communication using radio waves, for example, in accordance with a communication standard such as a specific low-power radio station in the 920 MHz band (a radio station that does not require a license).

[0038] The second communication unit 31 is configured to be capable of communicating with a presentation unit 41, which will be described later, via a third communication unit 45 of the display device 4. The second communication unit 31 receives the measurement results of each of the plurality of measurement devices 1 transmitted from the first communication unit 21 and transmits the measurement results to the presentation unit 41 via the third communication unit 45.

[0039] In this embodiment, the second communication unit 31 is configured to be capable of wireless communication with the presentation unit 41 via a third communication unit 45 (to be described later) of the display device 4. In short, the second communication unit 31 receives from the first communication unit 21 the measurement result transmitted by the second communication unit 31 (that is, the measurement result measured by the measurement unit 11 in the measurement device 1 selected by the user's operation), and transmits the received measurement result to the presentation unit 41 via the third communication unit 45 by wireless communication. According to this configuration, the presentation unit 41 of the display device 4 can receive the measurement result of the measurement unit 11 in the measurement device 1 selected by the user's operation at an arbitrary location. That is, the user can confirm the measurement result of the measurement unit 11 presented by the presentation unit 41 at an arbitrary location. In short, the measurement system 100 of this embodiment has an advantage that the usability when confirming the measurement result of the measurement unit 11 can be further improved. Note that the communication method between the second communication unit 31 and the third communication unit 45 is wireless communication using radio waves conforming to a communication standard such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0040] In this embodiment, the wireless communication possible distance between the first communication unit 21 of the driver 2 and the second communication unit 31 of the controller 3 is longer than the wireless communication possible distance between the second communication unit 31 of the controller 3 and the presentation unit 41 of the display device 4. According to this configuration, the second communication unit 31 of the controller 3 can be provided at a position away from the first communication unit 21 of the driver 2. In other words, there is an advantage that the second communication unit 31 of the controller 3 can be provided at a position away from the silo Y1 where each of the plurality of measurement devices 1 is installed.

[0041] The controller 3 is electrically connected to an external power supply P2, and electric power for driving the second communication unit 31 of the controller 3 is supplied from the external power supply P2. The external power supply P2 is, for example, an AC power supply of 100V or 200V. Although the external power supply P2 assumes a power supply different from the external power supply P1, it may be the same power supply.

[0042] (2-5) Display device The display device 4 is a terminal device operated by a user. The display device 4 mainly comprises a computer having a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and a memory. Specifically, the display device 4 is a tablet-type computer or a smartphone owned by the user. Note that the type of the processor is not limited as long as its functions can be realized by executing a program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Here, although referred to as an IC or an LSI, the name may vary depending on the degree of integration, and it may be called a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration). A field-programmable gate array (FPGA) programmed after the manufacture of the LSI, or a reconfigurable logic device capable of reconfiguring the bonding relationship inside the LSI or setting up the circuit sections inside the LSI can also be used for the same purpose. The plurality of electronic circuits may be integrated on one chip, or provided on a plurality of chips. The plurality of chips may be aggregated in one device, or provided in a plurality of devices.

[0043] As shown in FIG. 1, the display device 4 includes a presentation unit 41, an operation unit 42, an external connection unit 43, a power storage unit 44, a third communication unit 45, a setting unit 46, a storage unit 47, a conversion unit 481, an abnormality determination unit 482, and an output unit 483.

[0044] The presentation device 4 realizes some or all of the functions of the presentation unit 41, the operation unit 42, the third communication unit 45, the setting unit 46, the conversion unit 481, the abnormality determination unit 482, and the output unit 483 by installing dedicated application software and starting this application software. The application software (program) may be pre-recorded in the memory of a computer, may be provided through a telecommunication line, or may be recorded and provided on a recording medium such as a memory card.

[0045] The presentation unit 41 of this embodiment is a display unit 411 that displays the measurement results of the measurement units 11 in each of the plurality of measurement devices 1. More specifically, the display unit 411 presents the measurement results of the measurement units 11 in each of the plurality of measurement devices 1 in a manner that can be visually recognized by the user. The display unit 411 is, for example, a liquid crystal display, an organic EL (Electro Luminescence) display, or the like. The operation unit 42 has a function of receiving user operations. In this embodiment, the display device 4 is equipped with a touch panel display, and the touch panel display functions as the display unit 411 and the operation unit 42. However, the operation unit 42 is not limited to a touch panel display, and may be, for example, a keyboard, a pointing device, or a mechanical switch. The display content of the screen displayed by the display unit 411 will be described with specific examples in the section of "(2-6) Display Screen of the Display Unit" described later.

[0046] The third communication unit 45 is configured to be capable of wireless communication with the second communication unit 31 of the controller 3. The communication method between the second communication unit 31 and the third communication unit 45 is, for example, wireless communication using radio waves in accordance with a communication standard such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The third communication unit 45 outputs the measurement results of the measurement units 11 in each of the plurality of measurement devices 1 received from the second communication unit 31 to the display unit 411 and the conversion unit 481.

[0047] The display unit 411 further displays a plurality (four) of operation reception buttons OB11 (see FIG. 4) for receiving an operation of a user for starting the measurement of the measurement unit 11 in each of the plurality of measurement devices 1. The display unit 411 of the present embodiment displays the measurement results in each of the plurality of measurement devices 1 and the plurality of operation reception buttons OB11 described above on the same screen. In other words, the display unit 411 of the present embodiment causes the plurality of operation reception buttons OB11 described above to be displayed on the measurement result screen X1. Each of the plurality of operation reception buttons OB11 corresponds to each of the plurality of measurement devices 1, and the user selects the operation reception button OB11 corresponding to the measurement device 1 for which the user desires to start the measurement of the measurement unit 11 among the plurality of measurement devices 1. Further, when the user selects and long-presses the corresponding operation reception button OB11 described above, the operation unit 42 receives the user's operation at the operation reception button OB11.

[0048] When the third communication unit 45 receives a user operation for starting the measurement of the measurement unit 11 at the operation reception button OB11 by the operation unit 42, the third communication unit 45 wirelessly transmits a start operation signal indicating that the user operation has been received to the first communication unit 21 of the driver 2 via the second communication unit 31 of the controller 3. In other words, when the operation unit 42 receives a user operation for starting the measurement of the measurement unit 11 at the operation reception button OB11, the second communication unit 31 of the controller 3 wirelessly transmits the start operation signal transmitted from the third communication unit 45 to the first communication unit 21 of the driver 2. When the measurement control unit 22 of the driver 2 receives the start reception signal via the first communication unit 21, the measurement control unit 22 outputs a start control signal for causing the drive control unit 12 to measure the physical quantity of the contained material Y2 by the measurement unit 11 to the drive control unit 12 in the measurement device 1 selected by the user operation among the plurality of measurement devices 1. That is, when the first communication unit 21 of the driver 2 receives the start operation signal, the measurement unit 11 of the measurement device 1 selected by the user operation measures the physical quantity related to the amount of the contained material Y2. More specifically, when the first communication unit 21 of the driver 2 receives the start operation signal, the measurement unit 11 of the measurement device 1 selected by the user operation measures the internal empty height H1 in the silo Y1 where the contained material Y2 is not contained as the physical quantity related to the amount of the contained material Y2. According to the above configuration, when starting the measurement of the measurement unit 11, it is not necessary to move to the location where the measurement unit 11 or the driver 2 is installed, and it is possible to start the measurement of the measurement unit 11 at the location where the display unit 411 is provided. That is, there is an advantage that the user can easily start the measurement of the measurement unit 11.

[0049] The setting unit 46 includes a conversion setting unit 461, a display setting unit 462, and a timer setting unit 463.

[0050] The conversion setting unit 461 sets the density of the stored material Y2 and the shape of the silo Y1 as conversion setting information. The "shape of the silo Y1" as referred to herein includes the vertical height of the silo Y1 and the radius when viewed from the vertical direction of the silo Y1. The conversion setting unit 461 acquires the conversion setting information received by the operation unit 42 using the display setting screen X2 (see FIG. 5) displayed by the display unit 411. More specifically, the conversion setting unit 461 acquires the conversion setting information received by the operation unit 42 using the setting input fields X25, X26, X27, X28, X29 described later on the display setting screen X2.

[0051] The display setting unit 462 sets, as display setting information, to display at least any one of the inner space height H1, the remaining amount height H2, the ratio of the empty amount or the remaining amount of the stored material Y2, and the weight of the empty amount or the remaining amount of the stored material Y2 as the measurement results of the measurement units 11 in each of the plurality of measuring devices 1. The "ratio of the empty amount or the remaining amount of the stored material Y2" as referred to in the present disclosure is the ratio occupied by the volume of the empty amount or the remaining amount of the stored material Y2 with respect to the capacity of the silo Y1. Also, the "weight of the empty amount of the stored material Y2" is the weight of the stored material Y2 expected to enter the inner space of the silo Y1.

[0052] The display unit 411 further displays a display setting screen X2 (see FIG. 5) for setting to display at least any one of the inner space height H1, the remaining amount height H2, the ratio of the empty amount or the remaining amount of the stored material Y2, and the weight of the empty amount or the remaining amount of the stored material Y2 as the measurement results of the measurement unit 11. The display setting unit 462 acquires the display setting information received by the operation unit 42 using the above-described display setting screen X2 (see FIG. 5). More specifically, the display setting unit 462 acquires the display setting information received by the operation unit 42 using the selection forms F22, F23 described later on the display setting screen X2. According to the above configuration, there is an advantage that it becomes easy to change the measurement results of the measurement unit 11 displayed by the display unit 411 in an arbitrary manner.

[0053] In this embodiment, the display setting unit 462 sets, as display setting information, to display, as a measurement result of the measurement unit 11 in each of the plurality of measurement devices 1, any one of the inner space height H1, the remaining amount height H2, the ratio of the empty amount or the remaining amount of the stored item Y2, and the weight of the empty amount or the remaining amount of the stored item Y2. That is, in this embodiment, the user selects one of the radio buttons B22a and B22b (to be described later) on the selection form F22 (see FIG. 5) and any one of the radio buttons B23a, B23b, B23c, and B23d (to be described later) on the selection form F23 (see FIG. 5).

[0054] More specifically, when the radio button B22a for "empty amount display" is selected on the selection form F22 and the radio button B23a for "%" is selected on the selection form F23, the display setting unit 462 sets, as display setting information, to display the ratio of the empty amount of the stored item Y2 in units of "%" as a measurement result of the measurement unit 11. On the other hand, when the radio button B22b for "remaining amount display" is selected on the selection form F22 and the radio button B23a for "%" is selected on the selection form F23, the display setting unit 462 sets, as display setting information, to display the ratio of the remaining amount of the stored item Y2 in units of "%" as a measurement result of the measurement unit 11.

[0055] Also, when the radio button B22a for "empty amount display" is selected on the selection form F22 and the radio button B23b for "cm" is selected on the selection form F23, the display setting unit 462 sets, as display setting information, to display the inner space height H1 in units of "cm" as a measurement result of the measurement unit 11. On the other hand, when the radio button B22b for "remaining amount display" is selected on the selection form F22 and the radio button B23b for "cm" is selected on the selection form F23, the display setting unit 462 sets, as display setting information, to display the remaining amount height H2 in units of "cm" as a measurement result of the measurement unit 11.

[0056] Further, when the radio button B22a for "empty quantity display" is selected in the selection form F22 and the radio button B23c for "m" is selected in the selection form F23, the display setting unit 462 sets, as display setting information, to display the inner empty height H1 in the unit of "m" as the measurement result of the measurement unit 11. On the other hand, when the radio button B22b for "remaining quantity display" is selected in the selection form F22 and the radio button B23c for "m" is selected in the selection form F23, the display setting unit 462 sets, as display setting information, to display the remaining quantity height H2 in the unit of "m" as the measurement result of the measurement unit 11.

[0057] Further, when the radio button B22a for "empty quantity display" is selected in the selection form F22 and the radio button B23d for "ton" is selected in the selection form F23, the display setting unit 462 sets, as display setting information, to display the weight of the empty quantity of the contained object Y2 in the unit of "ton" as the measurement result of the measurement unit 11. On the other hand, when the radio button B22b for "remaining quantity display" is selected in the selection form F22 and the radio button B23d for "ton" is selected in the selection form F23, the display setting unit 462 sets, as display setting information, to display the weight of the remaining quantity of the contained object Y2 in the unit of "ton" as the measurement result of the measurement unit 11.

[0058] The timer setting unit 463 sets, in advance, as timer setting information, the measurement start time at which the measurement unit 11 measures a physical quantity related to the amount of the stored item Y2 (the internal empty height H1 of the silo Y1). The "timer setting information" as used herein also includes information on whether to set the measurement start time. Further, as an example, the "timer setting information" includes any one of "execute once" in which the measurement unit 11 measures only once at the measurement start time, "day-of-week designation" in which the measurement unit 11 repeatedly measures at the measurement start time every week on a pre-selected day of the week, and "daily designation" in which the measurement unit 11 repeatedly measures at the measurement start time every day. The display unit 411 displays a timer setting screen X3 (see FIG. 6) for setting in advance the measurement start time at which the measurement unit 11 measures a physical quantity related to the amount of the stored item Y2 (the internal empty height H1 of the silo Y1). The timer setting unit 463 acquires the timer setting information received by the operation unit 42 using the above-described timer setting screen X3. More specifically, the timer setting unit 463 acquires the conversion setting information received by the operation unit 42 using a selection form F31 and setting forms F32, F33, and F34, which will be described later, of the timer setting screen X3.

[0059] The third communication unit 45 wirelessly transmits a timer setting signal including the timer setting information to the first communication unit 21 of the driver 2 via the second communication unit 31 of the controller 3. Based on the timer setting signal received via the first communication unit 21, the measurement control unit 22 of the driver 2 causes the measurement unit 11 to start measuring a physical quantity related to the amount of the stored item Y2 (the internal empty height H1 of the silo Y1) at the measurement start time. In other words, based on the timer setting signal received via the first communication unit 21, the measurement control unit 22 of the driver 2 outputs, at the measurement start time, a start control signal for causing the drive control unit 12 to cause the measurement unit 11 to measure the physical quantity of the stored item Y2 to the drive control unit 12 in the corresponding measurement device 1. That is, the measurement unit 11 of the corresponding measurement device 1 measures the physical quantity of the stored item Y2 (the internal empty height H1 of the silo Y1) at the measurement start time. According to the above configuration, the measurement unit 11 can measure the physical quantity of the stored item Y2 (the internal empty height H1 of the silo Y1) without the user operating the operation reception button OB11. That is, there is an advantage that the usability of the measurement system 100 can be further improved.

[0060] The conversion unit 481 uses the conversion setting information set by the conversion setting unit 461 to convert the inner cavity height H1 measured by the measurement unit 11 in each of the plurality of measuring devices 1 into at least one of the remaining amount height H2, the ratio of the empty amount or the remaining amount of the contained object Y2, and the weight of the empty amount or the remaining amount of the contained object Y2. The presentation unit 41 presents, as the measurement result measured by the measurement unit 11 in the measuring device 1 selected by the user's operation, at least one of the inner cavity height H1, the remaining amount height H2, the ratio of the empty amount or the remaining amount of the contained object Y2, and the weight of the empty amount or the remaining amount of the contained object Y2. More specifically, the display unit 411, based on the display setting information, presents, as the measurement result measured by the measurement unit 11 in the measuring device 1 selected by the user's operation, the inner cavity height H1 measured by the measurement unit 11 in each of the plurality of measuring devices 1, or the remaining amount height H2 converted by the conversion unit 481, the ratio of the empty amount or the remaining amount of the contained object Y2, and a measurement result screen X1 (see FIG. 4) including at least one of the weights of the empty amount or the remaining amount of the contained object Y2. According to the above configuration, the display unit 411 can display the measurement results of the measurement unit 11 in various modes. As a result, there is an advantage that it becomes easier for the user to recognize the measurement results of the measurement unit 11.

[0061] In the measurement system 100 of the present embodiment, it is assumed that the silo Y1 has a columnar first portion Y11 and a second portion Y12 having a shape different from that of the first portion Y11, as shown in FIG. 2. Therefore, the "shape of the silo Y1" in the present embodiment includes the shapes of both the first portion Y11 and the second portion Y12 of the silo Y1. More specifically, the "shape of the silo Y1" in the present embodiment includes the vertical height of the first portion Y11 of the silo Y1, the radius of the upper base of the first portion Y11 of the silo Y1, the vertical height of the second portion Y12 of the silo Y1, and the radius of the lower base of the second portion Y12 of the silo Y1. For this reason, the conversion unit 481 uses the conversion setting information including the shapes of both the first portion Y11 and the second portion Y12 of the silo Y1 to convert the internal empty height H1 into at least one of the remaining height H2, the ratio of the empty amount or the remaining amount of the stored material Y2, and the weight of the empty amount or the remaining amount of the stored material Y2. According to the above configuration, the conversion unit 481 can convert the internal empty height H1 into at least one of the remaining height H2, the ratio of the empty amount or the remaining amount of the stored material Y2, and the weight of the empty amount or the remaining amount of the stored material Y2, more reflecting the actual shape of the silo Y1. That is, there is an advantage that the conversion accuracy of the conversion unit 481 can be improved.

[0062] In this embodiment, the conversion unit 481 converts the internal empty height H1 measured by the measurement unit 11 in each of the plurality of measuring devices 1 into the remaining amount height H2, the ratio of the empty amount or the remaining amount of the contained material Y2, and the weight of the empty amount or the remaining amount of the contained material Y2. Based on the display setting information, the display unit 411 displays, as the measurement result measured by the measurement unit 11 in the measuring device 1 selected by the user's operation, the internal empty height H1 measured by the measurement unit 11 in each of the plurality of measuring devices 1, or the remaining amount height H2 converted by the conversion unit 481, the ratio of the empty amount or the remaining amount of the contained material Y2, and a measurement result screen X1 (see FIG. 4) including any one of the weights of the empty amount or the remaining amount of the contained material Y2. Note that FIG. 4 illustrates the measurement result screen X1 when the display setting information is set so that the ratio of the empty amount of the contained material Y2 is displayed in the unit of “%” as the measurement result of the measurement unit 11. That is, FIG. 4 illustrates the measurement result screen X1 when the radio button B22a of “empty amount display” is selected in the selection form F22 on the display setting screen X2 (see FIG. 5) and the radio button B23a of “%” is selected in the selection form F23.

[0063] The abnormality determination unit 482 determines whether an abnormality has occurred in at least one of the silos Y1 in which each of the plurality of measuring devices 1 is installed, the measurement unit 11 in each of the plurality of measuring devices 1, the first communication unit 21 of the driver 2, and the second communication unit 31 of the controller 3. Examples of the abnormality occurring in the silo Y1 or the measurement unit 11 include that the motor for rotating the take-up drum 112 does not operate normally, or that the weight 115 does not hang down into the silo Y1 even though the above-described motor is operating normally. Examples of the abnormality occurring in the first communication unit 21 include that the first communication unit 21 is not connected to each of the plurality of measuring devices 1, or that the first communication unit 21 is in a situation where it cannot perform wireless communication with the second communication unit 31. Examples of the abnormality occurring in the second communication unit 31 include that the second communication unit 31 is in a situation where it cannot perform wireless communication with the first communication unit 21, or that the third communication unit 45 is in a situation where it cannot perform wireless communication with the second communication unit 31.

[0064] During the measurement by the measurement unit 11 of the physical quantity related to the amount of the contained material Y2 (the internal empty height H1 of the silo Y1), the abnormality determination unit 482 of the present embodiment determines whether an abnormality has occurred in the silo Y1 or the measurement unit 11 based on the detection result of the encoder of the measurement unit 11. Specifically, when the detection result of the encoder does not change before and after the motor of the measurement unit 11 operates normally, the abnormality determination unit 482 determines whether an abnormality has occurred in the silo Y1 or the measurement unit 11. Further, when the direction in which the motor of the measurement unit 11 moves does not match the detection result of the encoder, the abnormality determination unit 482 determines whether an abnormality has occurred in the silo Y1 or the measurement unit 11. Further, when the drive control unit 12 does not detect that the turn drum 114 has moved upward even after the elapse of the assumed time after the motor of the measurement unit 11 has operated normally (that is, when the weight 115 does not reach the upper surface of the contained material Y2 contained in the silo Y1), the abnormality determination unit 482 determines whether an abnormality has occurred in the silo Y1 or the measurement unit 11. Further, when the magnitudes of the detection results of the encoder when the weight 115 is hanging down in the silo Y1 and when the weight 115 is lifted in the silo Y1 do not match, the abnormality determination unit 482 determines whether an abnormality has occurred in the silo Y1 or the measurement unit 11.

[0065] The abnormality determination unit 482 of this embodiment determines whether an abnormality has occurred in the first communication unit 21 and the second communication unit 31 by having the first communication unit 21 and the second communication unit 31 perform wireless communication (i.e., test communication) in advance before the measurement unit 11 measures the physical quantity related to the amount of the stored item Y2 (the internal empty height H1 of the silo Y1). Specifically, the display unit 411 displays a communication test button OB22 (see FIG. 5) for receiving a user operation to start the test communication between the first communication unit 21 and the second communication unit 31. The display unit 411 of this embodiment displays the above-mentioned communication test button OB22 on the display setting screen X2. When the user selects the above-mentioned communication test button OB22, the operation unit 42 receives the user operation on the communication test button OB22. According to the above configuration, there is an advantage that the user can easily confirm the occurrence of an abnormality in the first communication unit 21 and the second communication unit 31.

[0066] When the operation unit 42 receives a user operation to start the test communication between the first communication unit 21 and the second communication unit 31 on the communication test button OB22, the third communication unit 45 wirelessly transmits a test start signal indicating the start of the test communication to the second communication unit 31 of the controller 3. When receiving the test start signal, the second communication unit 31 starts the test communication with the first communication unit 21. If there is a response from the first communication unit 21, the second communication unit 31 wirelessly transmits a test end signal indicating the end of the test communication to the abnormality determination unit 482 via the third communication unit 45. When the abnormality determination unit 482 receives the test end signal from the second communication unit 31 within a predetermined time, it determines that no abnormality has occurred in the first communication unit 21 and the second communication unit 31. On the other hand, when the abnormality determination unit 482 does not receive the test end signal from the second communication unit 31 within a predetermined time, it determines that an abnormality has occurred in at least one of the first communication unit 21 and the second communication unit 31.

[0067] When the abnormality determination unit 482 determines that an abnormality has occurred in any of the measurement devices 1, the third communication unit 45 wirelessly transmits an abnormality determination signal indicating that an abnormality has been determined to occur to the first communication unit 21 of the driver 2 via the second communication unit 31 of the controller 3. While the measurement unit 11 of the measurement device 1 determined to have an abnormality is measuring a physical quantity related to the amount of the contained substance Y2 (the internal empty height H1 of the silo Y1), when the abnormality determination unit 482 determines that an abnormality has occurred, the measurement control unit 22 of the driver 2 stops the measurement of the physical quantity by the measurement unit 11. More specifically, while the measurement unit 11 of the measurement device 1 determined to have an abnormality is measuring a physical quantity related to the amount of the contained substance Y2 (the internal empty height H1 of the silo Y1), when the measurement control unit 22 of the driver 2 receives an abnormality determination signal via the first communication unit 21, the drive control unit 12 outputs a stop control signal for stopping the measurement of the physical quantity of the contained substance Y2 by the measurement unit 11 to the drive control unit 12 in the measurement device 1. That is, while the measurement unit 11 of the measurement device 1 determined to have an abnormality is measuring a physical quantity related to the amount of the contained substance Y2, when the abnormality determination unit 482 determines that an abnormality has occurred, the measurement of the physical quantity related to the amount of the contained substance Y2 is stopped. According to the above configuration, there is an advantage that it is possible to suppress the measurement unit 11 from mismeasuring the physical quantity related to the amount of the contained substance Y2.

[0068] Further, when the measurement control unit 22 receives an abnormality determination signal via the first communication unit 21, that is, when the abnormality determination unit 482 determines that an abnormality has occurred, the measurement control unit 22 does not cause the measurement unit 11 to measure a physical quantity related to the amount of the contained substance Y2 (the internal empty height H1 of the silo Y1) until the operation unit 42 receives an operation of the user for canceling the notification of the abnormality. More specifically, when the abnormality determination unit 482 determines that an abnormality has occurred, the measurement control unit 22 does not output a start control signal for causing the drive control unit 12 to measure the physical quantity of the contained substance Y2 by the measurement unit 11 to the drive control unit 12 in the corresponding measurement device 1 until it receives a signal indicating that the notification of the abnormality has been canceled from the third communication unit 45.

[0069] The storage unit 47 includes a setting storage unit 471, a history storage unit 472, and an abnormality number storage unit 473. The storage unit 47 is the memory of the computer included in the display device 4, and is, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), or an EEPROM (Electrically Erasable Programmable Read Only Memory).

[0070] The setting storage unit 471 stores the information set by the setting unit 46. More specifically, the setting storage unit 471 stores the conversion setting information set by the conversion setting unit 461, the display setting information set by the display setting unit 462, and the timer setting information set by the timer setting unit 463. When the conversion unit 481 converts the inner cavity height H1 into each of the remaining amount height H2, the ratio of the empty amount or remaining amount of the contained object Y2, and the weight of the empty amount or remaining amount of the contained object Y2, the setting storage unit 471 outputs the conversion setting information to the conversion unit 481. Similarly, when the display unit 411 displays the measurement result screen X1 (see FIG. 4), the setting storage unit 471 outputs the display setting information to the display unit 411. When the third communication unit 45 transmits a timer setting signal including the timer setting information to the first communication unit 21 via the second communication unit 31, the setting storage unit 471 outputs the timer setting information to the third communication unit 45.

[0071] The history storage unit 472 stores, as history information for each measuring device 1, the measurement results of the measurement unit 11 in each of the plurality of measuring devices 1. In other words, the history storage unit 472 stores, as history information for each of the plurality of measurement units 11, the measurement results in each of the plurality of measurement units 11. The history storage unit 472 of the present embodiment is configured to delete, in order, the measurement results with older storage timings when the number of stored measurement results reaches the maximum number. As an example, the history storage unit 472 of the present embodiment is configured to be able to store up to 30 measurement results as history information for each of the plurality of measurement units 11. The display unit 411 further displays a history display screen X6 (see FIG. 9) for presenting the history information stored by the history storage unit 472 for each of the plurality of measurement units 11. According to this configuration, there is an advantage that the user can easily check the history information.

[0072] The abnormality number storage unit 473 stores abnormality identification numbers that are each assigned in a one-to-one manner in advance to each of a plurality of abnormalities that can be determined by the abnormality determination unit 482. When the abnormality determination unit 482 determines that an abnormality has occurred, the abnormality number storage unit 473 outputs to the display unit 411 the abnormality identification number assigned to the abnormality. The display unit 411 displays, on the abnormality confirmation screen X5 (see FIG. 8), abnormality identification information indicating the abnormality identification number output from the abnormality number storage unit 473.

[0073] The output unit 483 outputs the measurement results of the measurement units 11 in each of the plurality of measurement devices 1 to an external storage device connected via the external connection unit 43. More specifically, the output unit 483 of the present embodiment outputs, as measurement results, the physical quantity of the stored material Y2 (the internal empty height H1 of the silo Y1) measured by the measurement unit 11 in each of the plurality of measurement devices 1, the timing (e.g., measurement date or measurement time, etc.) measured by the measurement unit 11, and information that can identify the measurement unit 11, to the external storage device. Here, the "external storage device" is, for example, an auxiliary storage device such as a memory card configured to be connectable to both the display device 4 and a device other than the display device 4. According to the above configuration, there is an advantage that the measurement results of the measurement unit 11 can be easily transferred to other devices.

[0074] The power storage unit 44 is a power source that supplies power for driving each component of the display device 4 such as the display unit 411 and the operation unit 42. The power storage unit 44 is a rechargeable secondary battery.

[0075] (2-6) Display Screen of the Display Unit Hereinafter, the display content of the screen displayed by the display unit 411 will be described with reference to FIGS. 4 to 9. Note that the display content of the display unit 411 described below is an example, and is not intended to limit the display content of the display unit 411, and can be changed as appropriate.

[0076] The display unit 411 displays a measurement result screen X1 (see FIG. 4), a display setting screen X2 (see FIG. 5), a timer setting screen X3 (see FIG. 6), an abnormality notification screen X4 (see FIG. 7), an abnormality confirmation screen X5 (see FIG. 8), and a history display screen X6 (see FIG. 9). Note that the dashed frames shown in FIGS. 4 to 9 are virtual frames shown for the purpose of explanation and are not the frames actually displayed by the display unit 411.

[0077] (2-6-1) Measurement Result Screen The measurement result screen X1 is a screen that displays the measurement results of each of the plurality of measurement devices 1. As shown in FIG. 4, the measurement result screen X1 includes a plurality (four) of result display columns X11, a plurality (four) of location display columns X12, a plurality (four) of timer display columns X13, a plurality (four) of operation reception buttons OB11, and screen transition buttons OB12, OB13, OB14.

[0078] Each of the four result display columns X11 corresponds to each of the four measurement devices 1, and the measurement result of the measurement unit 11 in the corresponding measurement device 1 is displayed. Specifically, in each of the four result display columns X11, based on the display setting information, either the internal height H1 measured by the measurement unit 11 in the corresponding measurement device 1, or the remaining amount height H2 converted by the conversion unit 481, the empty amount or the ratio of the remaining amount of the contained material Y2, and the weight of the empty amount or the remaining amount of the contained material Y2 is displayed.

[0079] As a specific example, Fig. 4 illustrates a measurement result screen X1 when display setting information is set so that the ratio of the empty volume of the contained material Y2 is displayed in units of "%" as a measurement result of the measurement unit 11. In the result display columns X11a to X11d shown in Fig. 4, the ratio of the empty volume of the contained material Y2 obtained by the conversion unit 481 converting the inner empty height H1 measured by the corresponding measuring device 1 is displayed in units of "%. Further, the date on which the first measuring device 1a measured the inner empty height H1 is also displayed in the result display columns X11a to X11d. Specifically, the text "20.0% (empty volume) 2021 / 7 / 14 (water)" is displayed in the result display column X11a, and the text "5.0% (empty volume) 2021 / 7 / 14 (water)" is displayed in the result display column X11b. Similarly, the text "10.0% (empty volume) 2021 / 7 / 14 (water)" is displayed in the result display column X11c, and the text "0.5% (empty volume) 2021 / 7 / 14 (water)" is displayed in the result display column X11d.

[0080] Each of the four location display columns X12 corresponds to each of the four measuring devices 1, and the identification name of the driver 2 to which the corresponding measuring device 1 is connected is displayed. Further, each of the four location display columns X12 also displays the identification name of the corresponding measuring device 1. Specifically, the text "Silos A Measuring Device A" is displayed in the location display column X12a, and the text "Silos B Measuring Device B" is displayed in the location display column X12b. Similarly, the text "Silos C Measuring Device C" is displayed in the location display column X12c, and the text "Silos D Measuring Device D" is displayed in the location display column X12d.

[0081] Each of the four timer display columns X13 corresponds to each of the four measuring devices 1, and the timer setting information set in the measuring unit 11 of the corresponding measuring device 1 is displayed. Specifically, assuming that the measuring unit 11 of the measuring device 1 corresponding to the timer display column X13a is set by the timer setting unit 463 to measure repeatedly every day at the measurement start time, the words "17:05 daily" are displayed in the timer display column X13a. Similarly, assuming that the measuring unit 11 of the measuring device 1 corresponding to the timer display column X13b is set by the timer setting unit 463 to measure repeatedly every week at the measurement start time on the pre-selected day of the week, the words "17:05 (Mon Tue Fri)" are displayed in the timer display column X13b. Also, assuming that the measuring unit 11 of the measuring device 1 corresponding to the timer display column X13c is set by the timer setting unit 463 to measure only once at the measurement start time, the words "2021 / 7 / 14(Wed) 17:05" are displayed in the timer display column X13c. Further, assuming that the measuring unit 11 of the measuring device 1 corresponding to the timer display column X13d has no measurement start time set by the timer setting unit 463, the word "OFF" is displayed in the timer display column X13d.

[0082] The four operation reception buttons OB11 correspond to each of the four measuring devices 1, and are buttons for receiving the operation of the user to start the measurement of the measuring unit 11 in the corresponding measuring device 1. Specifically, the words "Start" are displayed on the operation reception button OB11a. Similarly, the words "Start" are also displayed on the operation reception buttons OB11b, OB11c, and OB11d.

[0083] On the measurement result screen X1, the location display column X12a, the operation reception button OB11a, the result display column X11a, and the timer display column X13a are arranged in a row (along the left - right direction) and correspond to the same measuring device 1 among the four measuring devices 1. Similarly, the location display column X12b, the operation reception button OB11b, the result display column X11b, and the timer display column X13b are arranged in a row and correspond to the same measuring device 1 among the four measuring devices 1. Also, the location display column X12c, the operation reception button OB11c, the result display column X11c, and the timer display column X13c are arranged in a row and correspond to the same measuring device 1 among the four measuring devices 1. The location display column X12d, the operation reception button OB11d, the result display column X11d, and the timer display column X13d are arranged in a row and correspond to the same measuring device 1 among the four measuring devices 1.

[0084] The screen transition button OB12 is a button for receiving a user operation to transition from the measurement result screen X1 to the display setting screen X2. When the operation unit 42 receives a user operation on the screen transition button OB12, the display unit 411 transitions from the measurement result screen X1 to the display setting screen X2. Specifically, the text "Settings" is displayed on the screen transition button OB12.

[0085] The screen transition buttons OB13 and OB14 are buttons for receiving a user operation to transition from the measurement result screen X1 that displays the measurement results of the measurement units 11 in each of the plurality of measuring devices 1 connected to a driver 2 when the controller 3 performs wireless communication with a plurality of drivers 2, to another measurement result screen X1 that displays the measurement results of the measurement units 11 in each of the plurality of measuring devices 1 connected to a driver 2 different from the said driver 2. Specifically, the text "Previous Page" is displayed on the screen transition button OB13, and the text "Next Page" is displayed on the screen transition button OB14.

[0086] When the operation unit 42 receives a user operation on the screen transition buttons OB13 and OB14 while the display unit 411 is in a state where the controller 3 is performing wireless communication with a plurality of drivers 2, the display unit 411 transitions from the measurement result screen X1 to another measurement result screen X1. In this embodiment, since the controller 3 performs wireless communication with one driver 2, even if the operation unit 42 receives a user operation on the screen transition buttons OB13 and OB14, the display unit 411 does not transition from the measurement result screen X1 to another measurement result screen X1.

[0087] (2-6-2) Display setting screen The display setting screen X2 is a screen for setting the display unit 411 to display at least one of the inner cavity height H1, the remaining amount height H2, the ratio of the empty amount or remaining amount of the contained item Y2, and the weight of the empty amount or remaining amount of the contained item Y2 as the measurement result of the measurement unit 11. As shown in FIG. 5, the display setting screen X2 includes setting input fields X21 to X29, selection forms F21 to F23, screen transition buttons OB21, OB23 to OB25, a communication test button OB22, a save button OB26, and an initialization button OB27.

[0128] In the first communication step ST3, the first communication unit 21 wirelessly transmits the measurement result measured by the selected measurement unit 11 in the measurement step ST2 to the second communication unit 31 of the controller 3. Then, in the second communication step ST4, the second communication unit 31 receives the measurement result transmitted by the second communication unit 31 in the first communication step ST3 from the first communication unit 21, and wirelessly transmits the received measurement result to the presentation unit 41 via the third communication unit 45.

[0129] In the third communication step ST5, the third communication unit 45 outputs the measurement result transmitted from the second communication unit 31 in the second communication step ST4 to the display unit 411 and the conversion unit 481. Then, in the conversion step ST6, the conversion unit 481 uses the conversion setting information set by the conversion setting unit 461 to convert the internal empty height H1 measured by the selected measurement unit 11 into at least one of the remaining amount height H2, the ratio of the empty amount or the remaining amount of the contained object Y2, and the weight of the empty amount or the remaining amount of the contained object Y2. Thereafter, in the presentation step ST7, the presentation unit 41 presents the measurement result received by the second communication unit 31 in the second communication step ST4. More specifically, in the presentation step ST7, the presentation unit 41 presents at least one of the internal empty height H1, the remaining amount height H2, the ratio of the empty amount or the remaining amount of the contained object Y2, and the weight of the empty amount or the remaining amount of the contained object Y2 as the measurement result measured by the selected measurement unit 11. In the presentation step ST7 of the present embodiment, the display unit 411, based on the display setting information, displays a measurement result screen X1 (see FIG. 4) including at least one of the internal empty height H1 measured by the selected measurement unit 11 in the measurement step ST2 or the remaining amount height H2 converted by the conversion unit 481 in the conversion step ST6, the ratio of the empty amount or the remaining amount of the contained object Y2, and the weight of the empty amount or the remaining amount of the contained object Y2 as the measurement result measured by the selected measurement unit 11. That is, the presentation step ST7 of the present embodiment is a display step of displaying the measurement result of the selected measurement unit 11.
