Description

  The present invention relates to a flow rate monitoring system that has a plurality of terminal measuring devices that output detection values based on flow rates such as current and water flow, and monitors the output of the terminal measuring device.

  A conventional flow rate monitoring system is disclosed in Patent Document 1. This flow rate monitoring system includes a management device (system controller) and a plurality of wattmeters arranged on a current path flowing through power wiring such as a building. Each wattmeter outputs power based on the flow rate of current at each point, and a breaker that cuts off the current is integrally provided. The management device is communicably connected to each power meter, and monitors the output of each power meter. Thereby, the output of each wattmeter can be totaled and the electric power used inside a building etc. can be monitored.

  Further, a desired group for each power meter can be set and stored for each department. Thereby, the power consumption for each group can be analyzed in detail by extracting the power meter for each group by the management device and totaling the output.

JP 2011-38995 A (pages 4 to 8, FIG. 1)

  However, according to the conventional flow rate monitoring system, when the wattmeters on the same path are extracted when extracting the wattmeters for each predetermined group, the outputs of both are overlapped. As a result, the tabulation result for each group becomes inaccurate, and it is necessary for the user to select the wattmeters one by one so that the outputs of the respective wattmeters do not overlap during the tabulation for each group. Therefore, there is a problem that the convenience of the flow rate monitoring system is poor.

  An object of this invention is to provide the flow volume monitoring system which can improve the convenience.

A plurality of terminal measuring devices arranged on a current or fluid path to output detection values based on these flow rates;
While monitoring the output of each terminal measuring device, the management units consisting of each of the terminal measuring devices or a plurality of the terminal measuring devices arranged downstream of one point are classified into a predetermined group, and the management units are grouped by group. A management device that can total the output of
In the flow monitoring system with
In correspondence with each management unit, the management device holds a database including data indicating the management unit adjacent upstream, data indicating the management unit adjacent downstream, and data of the group,
When the group for one management unit is input and set, if the group of the management unit installed upstream and downstream of the one management unit has already been set, warning notification or input prohibition of the group is prohibited. It is characterized by doing.

  According to this configuration, for example, an ID number of each terminal measuring device which is a management unit, an ID number of a terminal measuring device adjacent to each upstream and downstream, and a database including a desired group are stored by user input. Thereby, the output of a terminal measuring device can be totaled according to group by the management apparatus. When setting the input of one terminal measuring device group, it is determined whether or not all the upstream and downstream terminal measuring device groups have been set. Then, when any of the upstream and downstream terminal measuring device groups for one terminal measuring device has been set, warning notification or group input prohibition is performed.

According to the present invention, in the flow rate monitoring system configured as described above, the management device can select a desired management unit from an input screen displaying a list of each management unit and set the group. In addition to displaying a predetermined first mark on the input screen for the set management unit,
When the group of the management units installed upstream and downstream of the one management unit is already set, a second mark different from the first mark is displayed on the input screen to give a warning notification Yes.

  Further, in the flow rate monitoring system configured as described above, when the group is set for the management unit having the management unit adjacent downstream, all the unset management units connected downstream are set. Is characterized in that a first mark is displayed.

  According to the present invention, in the flow rate monitoring system configured as described above, the output of the terminal measuring device is composed of electric power, and the database classifies the management unit according to use, and the management unit is classified according to installation location. And the data of the group.

  In the flow rate monitoring system configured as described above, when the group is input and set, the process of determining whether or not the group of the management unit adjacent to the upstream has been set is restarted, and the downstream The process of determining whether or not the group of the management unit adjacent to is already set is performed recursively.

  According to the present invention, when a group for a management unit composed of one or a plurality of terminal measuring devices is input and set, warning notification or input prohibition is performed when a group of management units installed upstream and downstream is already set. Therefore, it is possible to easily prevent duplication when the output of the management unit is aggregated by group. Therefore, the convenience of the flow rate monitoring system can be improved.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of a flow rate monitoring system according to an embodiment. The flow rate monitoring system 1 includes a management device 10 and a plurality of wattmeters 100 (terminal measuring devices) arranged on a path of current flowing through the power wiring 2 such as a building.

  The wattmeter 100 outputs the electric power based on the flow rate of the current at each point on the path branched in a tree shape as a detection value. The wattmeter 100 is integrally provided with a breaker (not shown) that cuts off the current. For ease of explanation, the same reference numerals (101 to 172) as the ID numbers described later are given to the respective wattmeters 100 in the figure.

  The management device 10 is configured by a personal computer or the like, and a communication unit 12, a display unit 13, an operation unit 14, and a storage unit 15 are connected to a control unit 11 including a CPU that controls each unit. The communication unit 12 communicates with each wattmeter 100 via the communication line 3. The display unit 13 displays an operation screen and a monitoring screen of the management apparatus 10. The operation unit 14 performs an input operation using a keyboard, a mouse, or the like. The storage unit 15 includes a RAM, a ROM, a hard disk, and the like. The storage unit 15 stores an operation program of the management apparatus 10 and a database of a power meter 100 described later, and temporarily stores a calculation result of the control unit 11.

  The management apparatus 10 monitors the power output from the wattmeter 100 through communication between the communication unit 12 and each wattmeter 100. Thereby, the output of each wattmeter 100 can be totaled and the electric power used inside a building etc. can be monitored.

  As shown in Table 1, the storage unit 15 stores a database indicating the attributes of the wattmeters 101 to 172. The database corresponds to each wattmeter 101-172, ID number, name, group by use, group by department, ID number (parent ID) of wattmeter 101-172 adjacent upstream, adjacent downstream The ID numbers (child IDs) of the wattmeters 101 to 172 are included. Each data in the database is input by the operation unit 14.

  The management apparatus 10 can count the outputs of the wattmeters 100, which are management units, for each application or department group, with each wattmeter 100 as a management unit. For example, items such as “server”, “outlet”, “cooking”, “ventilation”, “lighting”, and “air conditioning” are provided in the group according to usage. In the group for each department, a department name item indicating the installation location of each wattmeter 100 is provided. In addition, an “unclassified” item that is set to an unclassified state is provided in the group by use and department.

  FIG. 2 shows a group input screen 21 of each wattmeter 100. The input screen 21 is provided with group selection units 22 and 23 for selecting groups at the top. The group selection unit 22 is formed by a combo box, and selectively selects a grouping type (by use or by department). The group selection unit 23 is formed by a combo box, and selects a group item. An update button 24 described later is provided on the right side of the group selection unit 23.

  Below the group selection units 22 and 23, a plurality of terminal display units 25 corresponding to each wattmeter 100 are displayed in a list. On the terminal display unit 25, the name of each wattmeter 100 and the group in the type selected by the group selection unit 22 are written side by side. A hierarchy button 25a is provided at the head of the terminal display unit 25 indicating the wattmeter 101 (name: XX building), the wattmeter 102 (name: warehouse power), etc. arranged at the branch point of the current path. By operating the hierarchy button 25a, it is possible to switch between unfolded display and non-display of the wattmeter 100 adjacent downstream.

  A check box 25b is provided on the left side of the name of each terminal display unit 25. The update button 24 is operated after a group is selected by the group selection units 22 and 23 and the check box 25b is checked. Thereby, a group corresponding to each wattmeter 100 is registered in the database. When the grouping type selection in the group selection unit 22 is changed, the group displayed on the terminal display unit 25 is rewritten in conjunction with the change.

  Further, the background color of the terminal display unit 25 corresponding to the wattmeter 100 whose group is not classified is displayed in white. The background color is displayed in green as a mark (first mark) for the terminal display unit 25 corresponding to the power meter 100 for which the group has been set. Thereby, the wattmeter 100 in which the group has been set can be easily visually recognized. At this time, when the wattmeter 100 having the wattmeter 100 adjacent to the downstream has already set the group, the terminal display unit 25 indicating the downstream wattmeter 100 is similarly displayed in green.

  FIG. 3 is a flowchart showing an operation at the time of group input setting on the input screen 21. When the check box 25b of the desired terminal display unit 25 is checked, the flowchart of FIG. In step # 11, it is determined by referring to the database stored in the storage unit 15 whether or not the wattmeter 100 corresponding to the checked terminal display unit 25 has the upstream adjacent wattmeter 100. If there is no wattmeter 100 adjacent upstream, the process proceeds to step # 14. If there is a power meter 100 adjacent to the upstream, the upstream discrimination process shown in FIG. 4 is called at step # 12.

  In step # 31 of the upstream determination process, it is determined with reference to the database whether the group is unclassified with respect to the wattmeter 100 adjacent upstream. At this time, it is determined independently for each type of group for each use and each department. For example, when a group for each use is selected by the group selection unit 22, it is determined whether or not a group for each use is unregistered regardless of the setting state of the group for each department.

  When the power meter 100 adjacent to the upstream has already set a group, the process proceeds to step # 35, where True (true) is acquired as a return value, and the process returns to the parent process.

  When the power meter 100 adjacent to the upstream is in a state where the group is not classified, the process proceeds to step # 32. In step # 32, it is determined by referring to the database whether or not the wattmeter 100 adjacent upstream has the wattmeter 100 adjacent further upstream. When there is no wattmeter 100 adjacent to the upstream further upstream, the process proceeds to step # 36, and False (false) is acquired as a return value, and the process returns to the parent process.

  If there is a wattmeter 100 adjacent to the upstream further upstream, the upstream discrimination process of the figure is recursively called in step # 33. Thereby, the same processing is performed on the upstream wattmeter 100 upstream of the wattmeter 100 corresponding to the checked terminal display unit 25. In step # 34, it is determined whether or not the return value of step # 33 is True. When the return value of step # 33 is True, the process proceeds to step # 35, and True is acquired as the return value. If the return value of Step # 33 is False, the process proceeds to Step # 36, and False is acquired as the return value.

  As a result, if a group has already been set for any one of the wattmeters 100 on the upstream side of the route, True is acquired as a return value, and the process returns to the flowchart of FIG. 3. Further, if the group is not classified for all the upstream wattmeters 100 on the route, False is acquired as a return value, and the process returns to the flowchart of FIG.

  In step # 13 of FIG. 3, it is determined whether or not the return value of step # 12 is True. If the return value of Step # 12 is True, the process proceeds to Step # 21, and if the return value of Step # 12 is False, the process proceeds to Step # 14.

  In step # 14, it is determined by referring to the database whether or not the wattmeter 100 corresponding to the terminal display unit 25 has the wattmeter 100 adjacent downstream. When there is no downstream wattmeter 100, the process proceeds to step # 18. If there is a wattmeter 100 adjacent to the downstream, the downstream discrimination process shown in FIG. 5 is called at step # 15.

  In step # 41 of the downstream determination process, it is determined with reference to the database whether or not the group is unclassified with respect to the wattmeter 100 adjacent downstream. If the power meter 100 adjacent to the downstream has already set a group, the process proceeds to step # 45, where True is acquired as a return value, and the process returns to the parent process.

  If the power meter 100 adjacent to the downstream is in an unclassified group, the process proceeds to step # 42. In step # 42, it is determined by referring to the database whether or not the wattmeter 100 adjacent downstream has the wattmeter 100 adjacent further downstream. When there is no wattmeter 100 adjacent to the downstream further downstream, the process proceeds to step # 46, where False is obtained as a return value and the process returns to the parent process.

  If there is a wattmeter 100 adjacent to the downstream further downstream, the downstream discrimination process of FIG. Thereby, the same processing is performed for the wattmeter 100 further downstream of the wattmeter 100 corresponding to the checked terminal display unit 25. In step # 44, it is determined whether or not the return value of step # 43 is True. When the return value of step # 43 is True, the process proceeds to step # 45, and True is acquired as the return value. If the return value of Step # 43 is False, the process proceeds to Step # 46, and False is acquired as the return value.

  As a result, if a group has been set for any one of the wattmeters 100 on the downstream side of the route, True is acquired as a return value, and the process returns to the flowchart of FIG. 3. Further, if the group is not classified for all the wattmeters 100 on the downstream side on the path, False is acquired as a return value, and the process returns to the flowchart of FIG.

  In step # 16 of FIG. 3, it is determined whether or not the return value of step # 15 is True. If the return value of Step # 15 is True, the process proceeds to Step # 21, and if the return value of Step # 15 is False, the process proceeds to Step # 17.

  In step # 17, it is determined whether or not downstream discrimination processing has been performed for all wattmeters 100 adjacent downstream. When the downstream discrimination processing is not performed for all the wattmeters 100 adjacent to the downstream, the process returns to step # 15, and steps # 15 to # 17 are repeatedly performed. If downstream discrimination processing has been performed for all wattmeters 100 adjacent downstream, the process proceeds to step # 18.

  In step # 18, it is determined whether or not the check of the check box 25b is canceled and the selection of the terminal display unit 25 is cancelled. If the selection of the terminal display unit 25 has not been canceled, it is determined in step # 19 whether or not the update button 24 has been operated. When the update button 24 is not operated, the process returns to step # 18, and steps # 18 and # 19 are repeated.

  And if selection of terminal display part 25 is canceled, processing will be ended. When the update button 24 is operated, the group is registered in the database and the process proceeds to step # 20. In step # 20, the background color of the terminal display unit 25 is set to green, and the process ends. At this time, the background color of the terminal display unit 25 corresponding to the downstream wattmeter 100 is also set to green at the same time.

  If the return value is True based on the determination in Steps # 13 and # 16, a group has been set for either the upstream or downstream power meter 100. For this reason, as shown in FIG. 6, in step # 21, the terminal display unit 25 (indicated by 25 'in the figure) is displayed in a pink color whose background color is different from green as a mark (second mark). Thereby, warning notification is performed, and it can be easily determined that a group is set redundantly for the wattmeters 100 on the same route.

  In step # 22, it is determined whether or not the update button 24 has been operated. If the update button 24 is not operated, it is determined in step # 23 whether or not the check on the check box 25b is canceled and the selection of the terminal display unit 25 is cancelled. If the selection of the terminal display unit 25 has not been canceled, the process returns to step # 22, and steps # 22 and # 23 are repeated.

  When the update button 24 is operated, the group is registered in the database and the process is terminated. At this time, the background color of the terminal display unit 25 may be changed to another color (for example, yellow). If the selection of the terminal display unit 25 is canceled, the background color of the terminal display unit 25 is returned to the original color (white or green) in step # 24 and the process is terminated.

  Next, FIG. 7 is a flowchart showing an operation when the output of the wattmeter 100 is totaled by group by the management apparatus 10. In step # 51, the variable ID indicating the ID number of the wattmeter 100 is initialized and the lowest value 101 is substituted, and the variable Wt indicating the total power is initialized and 0 is substituted. In step # 52, the process waits until a group for aggregation is designated.

  When the group is designated, the process proceeds to step # 53, and it is determined whether or not the wattmeter 100 having the ID number indicated by the variable ID is set to the group designated in step # 52. If the wattmeter 100 corresponding to the variable ID is not set to the designated group, the process proceeds to step # 55, and if it is set, the process proceeds to step # 54. In addition, also when there is no wattmeter 100 of ID number which corresponds to variable ID, it transfers to step # 55.

  In step # 54, the output power W (ID) of the wattmeter 100 corresponding to the variable ID is added to the variable Wt. In step # 55, it is determined whether or not the variable ID is the maximum value of the ID number of the wattmeter 100. If the variable ID is not the maximum value of the ID number of the power meter 100, the variable ID is incremented in step # 56, and steps # 53 to # 56 are repeated.

  When the variable ID is the maximum value of the ID number of the wattmeter 100, the process proceeds to step # 57, and the total power indicated by the variable Wt is output to the display unit 13. Then, the process ends. Note that a plurality of groups may be selected, the same processing may be performed on each group, and the total power of each may be output.

  Further, although each wattmeter 100 is classified into a group as a management unit, a plurality of wattmeters 100 may be set as a management unit. That is, when the outputs of the plurality of wattmeters 100 arranged downstream of one point on the route are summed, the power on the point can be acquired. Thereby, even if it does not install a wattmeter in the point, the same state as the state where the wattmeter was installed is obtained. Therefore, a plurality of wattmeters 100 arranged downstream of one point may be handled like one wattmeter and grouped as one management unit.

  According to the present embodiment, when a group for each power meter 100 that is a management unit is input and set, the background color of the terminal display unit 25 is variable when the groups of the power meters 100 installed upstream and downstream have been set. Then, warning notification is performed. Thereby, the user can discriminate | determine that the group is duplicated with respect to the wattmeter 100 on the same path | route. Therefore, duplication when the output of the wattmeter 100 is tabulated by the management device 10 can be easily prevented, and the convenience of the flow rate monitoring system 1 can be improved.

  Further, a mark (first mark) in which the background color of the terminal display unit 25 is green is displayed on the input screen 21 for the power meter 100 in which the group has been set. In addition, when a group of wattmeters 100 installed upstream and downstream of one wattmeter 100 has been set, a mark (second mark) in which the background color of the terminal display unit 25 is set to a pink color different from green is input. It is displayed on the screen 21. Thereby, the user can easily visually recognize and determine that the group is set to be duplicated for the wattmeter 100 on the same route.

  In addition, the mark displayed on the input screen 21 may be performed not only by changing the background color of the terminal display unit 25 but also by changing the character color or font, adding a symbol, or the like.

  In addition, when a group is set for the wattmeter 100 having the wattmeter 100 adjacent to the downstream, the same mark with the background color green for all the unset wattmeters 100 connected downstream. Is displayed. Therefore, when the upstream power meter 100 has already set the group, it can be easily recognized that the group setting is unnecessary.

  Further, the database stored in the storage unit 15 includes data of a group in which the wattmeter 100 is classified by use, and data of a group in which the wattmeter 100 is classified by installation location. Thereby, the electric power classified according to different groups can be collected, and the convenience of the flow rate monitoring system 1 can be further improved.

  In step # 33, the process of determining whether or not the group of wattmeters 100 adjacent to the upstream has been set is performed again, and whether or not the group of wattmeters 100 adjacent to the downstream is set in step # 43. The process of discriminating is performed again. Thereby, the operation program of the flow rate monitoring system 1 can be simplified.

  In the present embodiment, the warning display is performed when the wattmeters 100 on the same route are set in duplicate, but the group input may be prohibited. That is, the terminal display unit 25 corresponding to the wattmeter 100 having the wattmeter 100 for which the group has been set upstream or downstream may be grayed out so that the check box 25b cannot be checked. At this time, the gray display of the terminal display unit 25 is canceled by setting the group to “unclassified” with respect to the wattmeter 100 for which the group has been set.

  In the present embodiment, the output of the wattmeter 100 is tabulated by the management apparatus 10, but the same configuration can be applied to other detection targets that flow along a path that branches in a tree shape. For example, it may be a fluid monitoring system that outputs and aggregates detection values based on the flow rate by a flow meter (terminal measuring device) or the like disposed on a fluid path such as a water flow.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the flow volume monitoring system which has a some terminal measuring device which outputs the detected value based on flow volume, such as an electric current and a water flow, and monitors the output of a terminal measuring device.
