Description

Technical Field

[0001] The invention relates to a measuring device and a wiring setting display method. Background Art

[0002] As a known measuring device, the one disclosed in Patent Document 1 below includes a set of current detection terminals and voltage detection terminals, the number of which corresponds to the number of channels, and calculates and displays the power of a circuit under test connected to the current detection terminals and voltage detection terminals. The set of current detection terminals and voltage detection terminals is configured to be capable of inputting a line current and a line voltage for each channel.

[0003] The measuring device disclosed in Patent Document 1, such as Figure 9 As shown in (a), there is a display unit for displaying a setting screen, on which the current input probe, V / A ratio (rate), wiring method, wiring diagram, confirmation measurement value, etc. are displayed. The channel mode and wiring method are set according to the circuit under test as the measurement object. Here, the channel mode refers to the combination of used channels among multiple channels, and the wiring method refers to the power measurement method, which indicates the connection method (wiring) between the circuit under test and the measuring device and the power calculation method. In addition, the types of wiring methods include single-phase two-wire (1P2W), single-phase three-wire (1P3W), three-phase three-wire (3P3W, 3P3W2M, 3V3A, 3P3W3M), three-phase four-wire (3P4W), etc. The symbols in parentheses may vary depending on the manufacturer. The following description uses the above symbols.

[0004] in addition, Figure 9 The example in (a) is an example in which a wiring method corresponding to a channel mode and a connection diagram showing wiring corresponding to the wiring method are displayed. Figure 9 The example in (b) is an example of displaying a drop-down list of channel modes.

[0005] The channel mode and wiring method are set in two stages. First, as the first stage, a channel mode representing a predetermined channel combination is selected. As the second stage, a wiring method corresponding to each channel combination in these channel modes is selected. In the first stage, a plurality of channel modes are displayed as a drop-down list on the setting screen, and the setting is completed by selecting from the list. Specifically, click (touch) the drop-down button ( Figure 9 (a) and open the drop-down list of wiring methods ( Figure 9 (b)) and select the desired wiring method from the drop-down list. After the setting is completed, multiple wiring methods are displayed on the setting screen, and a connection diagram showing the corresponding wiring is displayed below the wiring method ( Figure 10 ).

[0006] For example, when the channel mode of "1P2W 1P2W 1P2W 1P2W 1P2W 1P2W" is selected in the first stage, use one channel at a time. When the channel mode of "1P3W / 3P3W2M 1P2W 1P2W 1P2W 1P2W" is selected, CH1 and CH2 are used in combination (1P3W or 3P3W2M wiring method can be selected in the second stage), and other channels are used one at a time.

[0007] In this way, when the wiring method of the circuit to be measured (single-phase two-wire, single-phase three-wire, three-phase three-wire or three-phase four-wire, etc.) is selected on the setting screen, the operator connects the current detection terminals and voltage detection terminals of each channel used in the measurement to the circuit to be measured via the current detection probe and the voltage detection probe.

[0010] Patent Document 1: Japanese Patent Application Laid-Open No. 2010-175424 Summary of the Invention

[0011] (Problems to be Solved by the Invention)

[0012] However, in the above-mentioned prior art, when the number of channels increases and the number of wiring methods also increases, the number of combinations of channel modes and wiring methods in the drop-down list increases. Therefore, it is not realistic to display all of them on the drop-down list window. When only a part of them is displayed, display switching is required, and retrieval also takes time.

[0013] Therefore, an object of the present invention is to provide a measuring device and a wiring setting display method capable of compactly displaying wiring system options.

[0014] (Solutions to solve problems)

[0015] In order to solve the above-mentioned problems, one aspect of the measuring device of the present invention has the following features.

[0016] A measuring device includes: an input section including a plurality of channels having a voltage signal input section and a current signal input section; a storage section storing a plurality of channel combinations and an association indicating a wiring pattern of a power measurement method corresponding to the plurality of channel combinations; a display section displaying a matrix of one of the plurality of channels and one of the plurality of wiring patterns as rows and the other as columns; an operation section setting the wiring pattern associated with the association to a cell of the matrix; and a display control section displaying on the display section a case where the association is set to the set cell of the matrix.

[0017] According to the above configuration, by displaying a case where the association is set to the cell of the matrix of the channels and the wiring patterns (coloring within the cell or thickening the frame of the cell), the setting can be displayed compactly. Further, the setting can be performed by the setting operation (touching in the case of a touch panel, and clicking by a mouse or the like in the case of a general display), and thus the setting can be performed easily.

[0018] Further, another aspect of the measuring device of the present application is characterized in that the display control section displays the wiring pattern as the case where the association is set. Thus, by displaying the wiring pattern in the cell of the matrix, it is possible to know what wiring pattern is set to the channel by looking inside the cell, and thus it is easy to know the setting content.

[0019] Further, another aspect of the measuring device of the present application is characterized in that the association of the wiring pattern includes at least one channel one wiring pattern, two channel one wiring pattern, and three channel one wiring pattern, and for each cell, when the one channel one wiring pattern is set, the case where the association is set is displayed in the area of one cell, when the two channel one wiring pattern is set, the case where the association is set is displayed in the area of two cells combined, and when the three channel one wiring pattern is set, the case where the association is set is displayed in the area of three cells combined. Thus, it is possible to set and display two channels or three channels combined at a time, and thus it is possible to perform the setting quickly.

[0020] Further, another aspect of the measuring device of the present application is characterized in that the display control section displays the number of channels required for the wiring pattern in parallel with the display direction of the plurality of channels of the matrix. Thus, by displaying the number of channels required for the wiring pattern, it is possible to know the number of channels used when the wiring pattern is selected, and thus it is easy to allocate the wiring pattern to the channels.

[0021] Further, one aspect of the wiring setting display method of the present application has the following features.

[0022] A wiring setting display method is provided for a measuring device having an input unit, the input unit being provided with a plurality of channels having a voltage signal input unit and a current signal input unit. The method comprises: a storage step of storing in the storage unit an association between a plurality of channel combinations and a wiring method representing an electric power measurement method corresponding to the plurality of channel combinations; a display step of displaying on the display unit a matrix having the plurality of channels and one of the plurality of wiring methods as rows and another as columns; a setting step of setting the wiring method associated with the association for cells of the matrix using the operation input unit; and a display control step of displaying on the display unit the fact that the association has been set for the cells of the set matrix.

[0023] Furthermore, another aspect of the connection setting display method of the present invention is characterized in that, in the display control step, a process of displaying the connection method is performed as if the association has been set.

[0024] In addition, another aspect of the wiring setting display method of the present invention is characterized in that: the association of the wiring mode includes at least 1 channel 1 wiring mode, 2 channels 1 wiring mode, and 3 channels 1 wiring mode, and in the display control step, the following processing is performed: for each unit, when the 1 channel 1 wiring mode is set, the situation in which the association is set is displayed in the area of ​​one unit; when the 2 channels 1 wiring mode is set, the situation in which the association is set is displayed in the area in which the two units are combined; when the 3 channels 1 wiring mode is set, the situation in which the association is set is displayed in the area in which the three units are combined.

[0025] Another aspect of the wiring setting display method of the present invention is characterized in that the display control step includes performing processing for displaying the number of channels required for the wiring configuration in parallel with the display direction of the plurality of channels of the matrix.

[0052] Below, refer to Figure 1 An embodiment of the measuring device of the present invention will be described.

[0053] [Composition of the measuring device]

[0054] like Figure 1 As shown in FIG, a measuring device 1 includes an input unit 2, a control unit 3, a storage unit 4, an input operation unit 5, and a display unit 6, and is configured to measure the power of a circuit under test. The input unit 2 is configured to include a set of current detection terminals and voltage detection terminals, described below, corresponding to the number of channels. Each set of current detection terminals and voltage detection terminals is configured to input the line current I and line voltage U of the circuit under test to each channel. Furthermore, the input unit 2 includes an A / D converter (not shown) configured to sample the signals input via the current detection terminals and voltage detection terminals of each channel at a predetermined sampling cycle, convert them into digital data, and output them. Furthermore, as an example, the input unit 2 is configured to connect a current detection probe 27 to the current detection terminal of each channel, and to connect a voltage detection probe 31 to the voltage detection terminal. In this case, the current detection probe converts the detected line current into a voltage that varies according to the amplitude of the current value, and outputs the voltage. Therefore, the signal input to each current detection terminal via the current detection probe 27 is a voltage. As described above, this voltage represents the line current detected by the current detection probe 27. Therefore, to facilitate understanding of the present invention, in the following description, the signal input to each current detection terminal is referred to as the line current I. Alternatively, instead of using the current detection probe 27 and the voltage detection probe 31, a configuration may be employed in which the current detection terminals 11, 13, 15, 17, 19, 21, 23, and 25 and the voltage detection terminals 12, 14, 16, 18, 20, 22, 24, and 26 of each channel, described later, are directly connected to the circuit under test.

[0055] (Input section)

[0056] like Figure 1As shown in FIG, the input section 2 includes eight channels of current detection terminals connected to the current detection probes 27 and voltage detection terminals connected to the voltage detection probes 31. The line current I1 and the line voltage U1 from the set of the current detection terminal 11 and the voltage detection terminal 12 in the first channel CH1 are input to the input section 2. The line current I2 and the line voltage U2 from the set of the current detection terminal 13 and the voltage detection terminal 14 in the second channel CH2 are input to the input section 2. The line current I3 and the line voltage U3 from the set of the current detection terminal 15 and the voltage detection terminal 16 in the third channel CH3 are input to the input section 2. The line current I4 and the line voltage U4 from the set of the current detection terminal 17 and the voltage detection terminal 18 in the fourth channel CH4 are input to the input section 2. Line current I5 and line voltage U5 from the pair of current detection terminal 19 and voltage detection terminal 20 in the fifth channel CH5 are input to input section 2. Line current I6 and line voltage U6 from the pair of current detection terminal 21 and voltage detection terminal 22 in the sixth channel CH6 are input to input section 2. Line current I7 and line voltage U7 from the pair of current detection terminal 23 and voltage detection terminal 24 in the seventh channel CH7 are input to input section 2. Line current I8 and line voltage U8 from the pair of current detection terminal 25 and voltage detection terminal 26 in the eighth channel CH8 are input to input section 2. Line currents I1 to I8 are also referred to as "line current I" when not specifically distinguished, and line voltages U1 to U8 are also referred to as "line voltage U" when not specifically distinguished.

[0057] The input unit 2 converts the line current I input to each current detection terminal of channels CH1 to CH8 via the current detection probe 27 and the line voltage U input to the voltage detection terminal of each channel via the voltage detection probe 31 into digital data (current data Di for the line current I and voltage data Du for the line voltage U) using an A / D converter, and outputs them in a state that can identify which data of which channel.

[0058] (Display unit)

[0059] The display unit 6 is a display device such as an LCD (Liquid Crystal Display), and is configured to include a screen 6a and an image memory (not shown) described later. Screen 6a displays a matrix image (a setting image) consisting of columns of channels and rows of wiring patterns as a first transitional image. A second transitional image displays a connection diagram image showing the wiring status of the circuit under test, a connection diagram image showing the connection status of each current detection probe 27 and each voltage detection probe 31 connected to each channel with respect to the circuit under test, and power values. Therefore, based on the displayed connection diagram of the circuit under test, the operator can instantly and accurately grasp the specific connection status of the current detection terminals and voltage detection terminals of each channel with respect to the circuit under test. Furthermore, screen 6a displaying the matrix image is constructed in a dot matrix liquid crystal display, with pixels arranged in a matrix at the intersections of multiple signal lines and multiple scanning lines. The image memory (not shown) stores the addresses corresponding to the cells (pixels) that constitute the matrix image.

[0060] Regarding this matrix image, Figure 3 In the example, the eight channels CH1, CH2, CH3, CH4, CH5, CH6, CH7, and CH8 are displayed in columns from the left as channel columns, and the wiring system rows are displayed in rows from the top as 1P2W, 1P3W, 3P3W2M, 3P3W3M, 3V3A, and 3P4W.

[0061] In addition, Figure 3 In the diagram, words such as "one unit" (1Unit), "two unit groups" (2Units), and "three unit groups" (3Units) are displayed. The "unit" (Unit) is a current / voltage input circuit (component) for inputting signals such as line current I and line voltage U from a group of current detection terminals 25 and voltage detection terminals 26 to the control unit 3 located on the main body side of the measuring device 1. The current input circuit and the voltage input circuit form a set, and there are many types. Two monomer units of the same type can be used as a "two unit group", or one different unit can be used for each unit as a "two unit group". "One unit" is a circuit that is compatible with the 1 channel 1 wiring method ( Figure 3 In the example, it is the symbol corresponding to CH1-1P2W), and "two unit groups" are the symbols corresponding to the 2-channel 1 wiring method ( Figure 3 In the example, the symbols corresponding to CH6 and CH7 (3P3W2M) are used. The "three unit group" corresponds to the 3-channel 1 wiring method ( Figure 3In the example, these are symbols corresponding to CH2, CH3, and CH4 (3P4W). The unit acquires signals and performs computations in the processing unit 33 on the main body of the measuring device 1 or displays them on the display unit 6. It should be noted that a channel is a unit for signal processing on the main body of the measuring device 1, and one unit can be assigned to each channel.

[0062] (Control Department)

[0063] like Figure 2 As shown in FIG, the control unit 3 is configured to include a processing unit 33 and a display control unit 34. The display control unit, in accordance with an operating program stored in the storage unit 4, displays the text of the wiring method in the columns corresponding to each channel in the combination pattern and the rows corresponding to the wiring method. The wiring method represents the power measurement method corresponding to the channel combination pattern of each channel CH1 to CH8. The processing unit 33 performs power calculation processing based on the current data Di and voltage data Du output from the input unit 2. Furthermore, the processing unit 33 generates channel-wiring method association information (hereinafter referred to as association information) that associates multiple channel combinations (described later) with the wiring methods corresponding to these multiple channels, and stores this information in the storage unit 4.

[0064] (Storage Department)

[0065] The storage unit 4 is comprised of semiconductor memories such as ROM (Read Only Memory) and RAM (Random Access Memory). In addition to program memory for storing programs and various application programs used to implement this embodiment, it also includes association information memory and image memory. The association information memory stores association information that associates multiple channel combinations with wiring patterns indicating the power measurement methods corresponding to these channel combinations. The image memory stores information related to the cells, such as the color and thickness of the frames surrounding the cells that form the matrix image on screen 6a, the font and color information of text displayed within the cells, and background information containing the colors within the cells. Furthermore, when resetting a connection that did not exist at the time of configuration, the new association information is incorporated into the existing association information, and this association information is updated and registered in the storage unit 4.

[0066] (Input operation section)

[0067] The input operation unit 5 performs input operations by touching the columns of channels CH1 to CH8 and the rows of wiring schemes in the matrix image serving as the operation panel, specifically the columns of the channels for which the wiring scheme is to be set and the rows of the channels for which the wiring scheme is to be set. Examples of such touch operations include tapping and long-pressing. While the above example is for a touch panel display, the present invention is not limited thereto. For example, when the display is a display other than a touch panel display, a keyboard, a pointing device, a mechanical switch, or the like may be used as the input operation unit.

[0068] [Channel-wiring method related information settings]

[0069] Below, use Figures 1 to 5 The procedure for setting the associated information will be described. It is assumed that a current detection probe 27 is pre-connected to each of the current detection terminals 11, 13, 15, 17, 19, 21, 23, and 25 of each of the channels CH1 to CH8 constituting the input unit 2, and a voltage detection probe 31 is pre-connected to each of the voltage detection terminals 12, 14, 16, 18, 20, 22, 24, and 26.

[0070] First, an input operation is performed by touching a cell located at the intersection of the column of the channel for which a connection method is to be set and the row for which a connection method is to be set.

[0071] For example, Figure 3 As shown in the example, the channels for which the wiring system is to be set are CH3 and CH4 (i.e., the channel combination is CH3 and CH4), and the wiring system to be set for channels CH3 and CH4 is "3P3W2M." In this case, the user first touches the square where the column displaying channel CH3 intersects the row displaying the wiring system "3P3W2M." At this point, the input operation unit 5 transmits "CH3" information as channel information D1 and "3P3W2M" information as wiring system information D2 to the processing unit 33 and display control unit 34.

[0072] At this time, the information "CH4" as the channel information D1 and the information "3P3W2M" as the wiring information D2 are sent from the input operation unit 5 to the processing unit 33. The processing unit 33 generates association information that associates the channel mode of channels CH3 and CH4 with the wiring method "3P3W2M" based on the previous information D1, D2 and the current information D1, D2, and outputs the association information to the storage unit 4. The association information is stored in the storage unit 4. Simultaneously with the output of the above-mentioned association information to the storage unit 4, the display control unit 34 changes the background color of the unit to be touched and the unit related to the wiring method of the unit to a color other than the original background color, and displays the background image of the changed background color on the screen 6a of the display unit 6 ( Figure 4 In the example, both cells are of the same single color). It should be noted that the above-mentioned background color can also be changed to a background that can be distinguished from the background of the original cell, such as an image composed of multiple colors other than a single color. Then, when the finger leaves the panel, the display control unit 34 displays the text "3P3W2M" in the two squares (cells) where the display columns of channels CH3 and CH4 intersect with the display row of the wiring method "3P3W2M". At the same time, the outer frames of the two squares where the "3P3W2M" is displayed are colored (see Figure 5 ).

[0073] In addition, the above describes the process of setting the association information between channels CH3 and CH4 and the wiring method "3P3W2M". The association information between channel CH1 and the wiring method "1P2W", the association information between channel CH5 and the wiring method "1P2W", the association information between channel CH8 and the wiring method "1P2W", the association information between the channel modes of channels CH6 and CH7 and the wiring method "3P3W2M", and the association information between the channel modes of channels CH2, CH3, and CH4 and the wiring method "3P4W" have already been set using the above-mentioned setting method, and the wiring methods have already been displayed in the unit (the box has been highlighted).

[0074] If the above setting changes and the associated information is different from the previously set one, the extra channels in the associated information are automatically set to the measurement mode for the individual channels (see Figure 5 CH2). Furthermore, if there are two or more redundant channels, it can be used for multi-channel measurement. If there are unset (empty) cells after the settings are changed, you can continue to set related information using the same steps as above.

[0075] The following describes the configuration of the setting screen, the unit structure that constitutes the screen, the setting change function, and the transition of the screen display state.

[0076] [Configuration of the setting screen]

[0077] Figure 6 The configuration of the screen 6a is shown in FIG. 6B. The screen 6a is configured by arranging columns in the X-axis direction at equal intervals for each channel (displayed in the X-axis direction), the column being a column in which cells having a state transition function (Wiring Select Window Cell) are arranged at equal intervals for each wiring mode (displayed in the Y-axis direction) (vertical column: Wiring Select Window Column (Wiring Select Window Column 1 to Wiring Select Window Column n (n is an integer of 2 or more) ) ). Above each column (Wiring Select Window Column: Column 1 to Column n (n is an integer of 2 or more) ), the corresponding channel name (CH1 to CHn (n is an integer of 2 or more) from left to right) is displayed, and on the left side of Column 1, the type name of the wiring mode is displayed from top to bottom. In the cell, the wiring mode is displayed as text under a prescribed condition. Figure 6 The frame surrounded by the broken line in FIG. 6B). Above each column (Wiring Select Window Column: Column 1 to Column n (n is an integer of 2 or more) ), the corresponding channel name (CH1 to CHn (n is an integer of 2 or more) from left to right) is displayed, and on the left side of Column 1, the type name of the wiring mode is displayed from top to bottom. In the cell, the wiring mode is displayed as text under a prescribed condition.

[0078] [Structure of the cell (configuration)]

[0079] As shown in FIG. 6C, the cell constituting the screen 6a is configured by a wiring cell (Wiring Cell) that receives a touch panel operation, a 4-side border, a coloring cell (Coloring Cell) for coloring the inside of the cell, and a cell text (Cell Text) that displays the wiring mode. Figure 7 As shown in FIG. 6C, the cell constituting the screen 6a is configured by a wiring cell (Wiring Cell) that receives a touch panel operation, a 4-side border, a coloring cell (Coloring Cell) for coloring the inside of the cell, and a cell text (Cell Text) that displays the wiring mode.

[0080] [Setting change function]

[0081] When each cell region is touched, a function (stored in the storage section 4) that changes the wiring mode corresponding to the channel is called, and the system variable is changed in accordance with the function.

[0082] [State transition function of the screen]

[0083] When the update of the system variable is successful, the update notification is sent from the display control section 34 to each cell in the screen 6a, and when all the cells receive the update notification, the processing of the state change of the screen 6a is started. Specifically, each cell reads from the system variable the information of which wiring mode (current wire) the system variable of the channel that the cell itself handles becomes, and the information of the index (how many from the left side (current wire index) ) when the same wiring mode is set across two or more channels, and performs the state transition in accordance with the values.

[0084] Hereinafter, referring to FIG. 7, the state transition of the screen 6a will be described. Figure 8The flowchart of FIG. 1 illustrates the state transition process of the screen 6 a performed by the display control unit 34 . Figure 8 "My Wire" in the dialog box refers to the wiring method corresponding to the unit you touched (the specified unit), "Current Wire" refers to the wiring method corresponding to a certain channel, and "Current Wire Idx" refers to the index within the wire corresponding to a certain channel.

[0085] exist Figure 8 In the process, first, when the "current wiring" is different from the "my wiring" ("No" in step S101), the wiring mode is converted to non-display "NO_WIRE" (steps S101, S102). When the "current wiring" is the same as the "my wiring" ("Yes" in step S101), the process proceeds to step S103.

[0086] In step S103, if "My Wiring" is "1P2W" ("Yes" in step S103), the wiring method you want to set for the unit in one channel (in this case, "1P2W") is displayed (step S104), and the process ends. If "My Wiring" is not "1P2W" ("No" in step S103), the process proceeds to step S105.

[0087] In step S105, when "My Wiring" is "1P3W" or "3P3W2M" ("Yes" in step S105), the process proceeds to step S106 for setting the same wiring method across two channels. When the wiring method to be set is not "1P3W" or "3P3W2M" ("No" in step S105), the process proceeds to step S109.

[0088] In step S106, a determination is made as to whether the index (current Wire Idx) is "0" (i.e., whether the cells forming the two channels are located on the left). If the index (current Wire Idx) is "0" ("Yes" in step S106), the desired wiring pattern to be set at the center of the area after the two channels are combined is displayed (step S107). If the index (current Wire Idx) is not "0" (i.e., 1) ("No" in step S106), the cell text is set to non-display (step S108), and the process ends.

[0089] In step S109, when "My Wiring" is any one of "3P3W3M", "3V3A", and "3P4W" ("Yes" in step S109), the process proceeds to step S110 in which the same wiring method is set across three channels. When "My Wiring" is not any one of "3P3W3M", "3V3A", and "3P4W" ("No" in step S109), the process ends without processing (step S115).

[0090] In step S110, a determination is made as to whether the index (current Wire Idx) is "0" (whether the cells constituting the three channels are located on the left). If the index (current Wire Idx) is "0" ("Yes" in step S110), the cell text is set to non-display (step S111). If the index (current Wire Idx) is not "0" ("No" in step S110), a determination is made as to whether the index (current Wire Idx) is "1" (whether the cells constituting the three channels are located in the center) (step S112).

[0091] In step S112, when the index (current Wire Idx) is "1" ("Yes" in step S112), the wiring method you want to set at the center of the cell of the three channels is displayed (step S113); when the index (current Wire Idx) is not "1" ("No" in step S112), the cell text is set to non-display (step S114), and the processing ends.

[0092] [Second transition screen]

[0093] The screen displayed during the above settings is the settings screen (the first transition screen). Once the settings are complete, the second transition screen displays: a wiring diagram showing the wiring status of the sink circuit based on the settings, and a terminal connection diagram showing the connection status of each channel's current detection terminal and voltage detection terminal to the sink circuit. This second transition screen is identical to the content described in the background section above, so a detailed explanation will be omitted.

[0094] [Color change function]

[0095] The display control unit 34 changes the color and background color of the cell border, as well as the display control related to the range of these changes, using a function different from the one used for the aforementioned state transitions. When a touch operation is detected on each cell, the display control unit 34 changes the color of the cell border and the width of the cell border according to the desired channel and wiring configuration. When the finger is removed, the display control unit 34 returns the cell border color and width to their original values.

[0096] [Effect]

[0097] According to the above embodiment, the user of the device can simultaneously set the channel combination and the wiring method (measurement method), thereby eliminating the "missing measurement method setting" that can occur with conventional methods. Furthermore, when there are dozens of channel-wiring method combinations, wiring settings can be made without the time-consuming process of scrolling through screens to select a desired channel-wiring method combination, as with conventional methods. Furthermore, the user can freely combine any adjacent channels and intuitively set wiring.

[0098] The embodiments of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiments, the input unit has eight channels, but the number of channels is not limited to this.
