  On the other hand, the monitoring controller 4 (abnormality prediction monitoring program) includes means for selecting a single item or a combination of a plurality of items from the information of each device 10 collected from the device-side controller 12, and the selected item, Means for setting an alarm condition for a combination of a plurality of items. Further, there is also provided means for issuing an alarm when the selected item or a combination of a plurality of items matches the alarm condition.

  The monitoring controller 4 (abnormality prediction monitoring program) issues an alarm when the set item matches the alarm condition. Specifically, when the information collected from each device-side controller 12 and the set item match the alarm condition, the monitoring-side controller 4 sends the abnormality information of the device 10 to the maintenance company's mobile phone by e-mail. Transmission (corresponding to means for issuing an alarm of the present invention).

  As a result, a maintenance contractor prepares tools and parts necessary for repairing the device 10 in advance, and deals with the store 8 with the store name recorded in the received mail in a precise and prompt manner. Will be performed. The monitoring controller 4 also displays the abnormality information of the device 10 on the display device 14 when the information collected from each device-side controller 12 and the set item match the alarm condition.

  Next, referring to FIGS. 2 to 3, the remote monitoring system 1 sets the name of a store that collects information, and means for setting an alarm condition for a selected item or a combination of a plurality of items; The means for selecting a single item or a combination of a plurality of items from the information of each device 10 collected from the device-side controller 12 will be described in detail step by step. Note that the database of the monitoring controller 4 stores a plurality of store names and devices 10 connected to the network 6 in advance. Further, it is assumed that the monitoring-side controller 4 acquires information (information for detecting an abnormality) related to the operating state from the device-side controller 12 installed in each store 8 in real time.

  In Procedure I, the name of the store where information is collected is set. That is, when the abnormality prediction monitoring program stored in the memory of the monitoring controller 4 is executed, a store name registration screen is displayed on the display device 14, and a plurality of store names stored in the database are displayed on the store name registration screen. Is displayed. Then, the maintenance company operates the input device 16 (mouse) to select an arbitrary store name from among a plurality of store names displayed on the store name registration screen. Next, the maintenance company places the cursor of the input device 16 on the OK mark displayed on the display device 14 and clicks. Thereby, the name of the store from which information is collected is selected and determined.

  In Procedure II, the alarm name or abnormal state (in this case, only the name) is set. That is, when the setting of the store name in the procedure I is completed, an alarm name setting screen (not shown) is displayed on the display device 14, and alarm names such as a communication abnormality and an operation load abnormality of the device 10 are displayed on the alarm name setting screen. . Then, the maintenance company places the cursor of the input device 16 on an alarm name such as a communication error displayed on the alarm name setting screen and an operation load error of the device 10 and clicks. Thereby, an alarm name or an abnormal state is set and determined.

  In Procedure III, an explanation will be given of detecting an abnormal state of the device 10 and issuing an alarm. First, in III-1 of the procedure III, selection of an item and setting of an alarm condition for a combination of a plurality of items (single or plural from information collected from the device-side controller 12 of the present invention) This corresponds to a means for selecting a combination of items). That is, when the procedure II is completed, a variable registration screen G1 for inputting items (items in the figure) and determination formulas is displayed on the display device 14 (FIG. 2).

  A left and right horizontally long first item input frame A1 for selecting an item is displayed on the left side of the variable registration screen G1, and a right and left horizontally long second item input frame A2 for selecting a second item is displayed on the right side. It is displayed. In addition, a determination input frame J1 for determining both items is displayed between the first item input frame A1 and the second item input frame A2. When the maintenance company clicks the cursor of the input device 16 on the first item input frame A1, the screen displayed on the display device 14 is switched to display the item selection screen G2, and the item selection screen G2 includes a database. A plurality of item names stored in is displayed (FIG. 3).

  Next, the maintenance contractor operates the input device 16 to select an arbitrary item for issuing an alarm when the device 10 is abnormal from a large number of items displayed on the item selection screen G2, and moves the cursor to it. When clicked, the selected item is determined and registered. At this time, in the item displayed on the item selection screen G2, information (not shown) obtained in real time by the monitoring controller 4 from the device controller 12 is displayed on the right side of the item. Note that variables are assigned in order from X00 to X01, X02,... To a plurality of items registered in the first item input frame A1. The monitoring controller 4 may display information acquired in real time from the device controller 12 in succession by a plurality of item names displayed on the item selection screen G2.

  Then, the maintenance contractor selects information (information) to be a detection parameter for issuing an alarm when the device 10 is abnormal, from information acquired in real time from the device-side controller 12 of the store 8 by the monitoring controller 4. The parameters include, for example, the suction temperature and discharge temperature or wind speed of the compressor and the indoor unit collected in real time from the device side controller 12 provided in the store 8 by the monitoring controller 4 and the heat exchange coil temperature of the air conditioner. And heat exchange liquid temperature, outside air temperature, outdoor unit fan speed control, current value, frequency and the like.

  Next, when the maintenance company places the cursor of the input device 16 on the second item input frame A2 displayed on the right side of the variable registration screen G1 (FIG. 2) and clicks it, the same as the first item input frame A1 is stored in the database. A plurality of item names are displayed (FIG. 3). Then, the maintenance contractor operates the input device 16 to select an arbitrary item for issuing an alarm when the device 10 is abnormal from among a large number of items displayed on the item selection screen G2, and clicks with the cursor Then, the selected item is determined.

  Also at this time, the item displayed on the item selection screen G2 is displayed on the item selection screen G2 in the same manner as described above, and the information on the device 10 that the monitoring controller 4 acquires from the device controller 12 in real time is displayed on the right of the item. The That is, the monitoring controller 4 selects, from the information acquired from the device-side controller 12 of the store 8 in real time, the detection parameter for issuing an alarm when the device 10 is abnormal. The parameters can be corrected with the input device 16 (keyboard) by clicking the variables, floating point constants, integer constants, etc. displayed on the variable registration screen G1 with the input device (mouse). Corrections are made accordingly. Further, in the following description, for the items in the first item input frame A1, a numerical value is input to the second item input frame A2, and this numerical value is used as a determination condition.

  Moreover, in III-2 of the procedure III, it is determined whether the device 10 is in an alarm state (means for setting an alarm condition for a selected item of the present invention or a combination of a plurality of items) Equivalent). Then, the maintenance contractor places the cursor of the input device 16 on the left and right horizontally long item selection frame K1 displayed on the left side of the variable registration screen G1 (illustrated in FIG. 2), and clicks to select the first item. Place the cursor of the input device 16 on the left and right horizontally long item input screen K2 displayed on the right side, and click to select the second item.

  Then, after the two items are selected, a determination symbol for issuing an alarm when the device 10 is abnormal is displayed in the horizontally long determination input frame J1 displayed between the left and right item selection frames K1 and K2. Selected. To select a judgment symbol, place the cursor of the input device 16 on the triangle mark (▼) provided on the right side of the judgment input frame J1 and click to display the judgment symbol used for judgment in a pull-down menu (not shown). Is done.

  In the memory of the monitoring controller 4, a plurality of determination symbols (AND, OR, bit, or =,>, <, etc.) input in advance in the determination input frame J1 are registered. Then, when the maintenance company operates the input device 16 to select an arbitrary determination symbol displayed on the pull-down menu, moves the cursor, and clicks, the selected determination symbol is input in the determination input frame J1. . The abnormality prediction monitoring program has functions such as change, addition, and deletion of set information (items, determination symbols, etc.), but description of these functions is omitted.

  Thereby, a determination formula for issuing an alarm when the device 10 is abnormal is determined. Further, when an abnormality is detected from a plurality of pieces of information when an abnormality occurs in the device 10, the procedures III-1 to III-2 are repeatedly executed to set a final determination formula. In the second item input frame A2, a numerical value serving as a reference for an alarm when the device is abnormal is input in advance for the information of the item selected in the first item input frame A1. Also in this case, the parameter for issuing an alarm when the device is abnormal can be corrected by the input device (keyboard), and is corrected as necessary.

  In step III-3 of procedure III, setting for issuing an alarm from a plurality of pieces of information about an abnormality of the device 10 (means for issuing an alarm when a selected item of the present invention or a combination of a plurality of items matches an alarm condition Equivalent). That is, upon completion of III-2 of the procedure III, an alarm registration screen G3 as shown in FIG. 4 is displayed, and a final determination formula for issuing an alarm when an abnormality occurs in the device 10 is registered on the alarm registration screen G3. To do. In this alarm registration screen G3, an alarm registration name, a detection condition, a judgment formula, an alarm condition, an alarm time (time to alarm), and the like are set. The alarm registration screen G3 will be described in detail later.

  After setting the final judgment formula, the maintenance contractor sets a delay time until an email indicating that an abnormality has occurred in the device 10 is transmitted to the mobile phone using the input device 16. Once the delay time has been set, the destination of the email to which the alarm is sent is registered (email address registration) to complete. Then, the setting as described above is performed for each store 8 that issues an alarm of the device 10 and for each device 10. As a result, a maintenance contractor's mobile phone contracted with the store 8 can be notified by sending an e-mail warning that the device 10 is abnormal even if the device 10 is abnormal in any store 8 It becomes.

  Next, alarm registration for giving an alarm when an abnormality occurs in the operation state of the device 10 will be described in detail with reference to FIG. In this description, a warning will be described when a malfunction occurs in the communication system of the device 10 installed in the store 8. In this case, the communication registration application malfunction of the device 10 is registered in the alarm registration name and the communication abnormality of the device 10 is registered in the detection condition name on the alarm registration screen G3. Further, predetermined information and numerical values are input to the first item input frame A1, the second item input frame A2, and the determination input frame J1, and a determination formula is already set.

  Information collected from the device-side controller 12 is displayed on the alarm registration screen G3 displayed on the display device 14, and the abnormality prediction monitoring program determines whether or not an abnormal state has occurred in communication from a large amount of collected information. Judgment is made. That is, the first determination formula is displayed in the first line (variable X00) on the top of the screen displayed on the alarm registration screen G3. In the first determination formula, the item (the item input in the first item input frame A1 of the variable registration screen G1) is G13 lunch communication error and the determination symbol is! =, Bit 0 is set as a determination condition in the item (the item input in the second item input frame A2 of the variable registration screen G1). That is, in the first determination formula (G13 lunch communication error! = 0), when the bit is other than 0, it means a condition for detecting a communication abnormal state.

  In the second line from the top of the alarm registration screen G3 and in the following lines (variables X01 to X06), a determination formula for detecting a communication abnormality similar to the first determination formula is defined. . That is, a plurality of items (items input in the item input frame A1 of the variable registration screen G1) are set on the left side, and determination symbols related to communication error bits are set on the right side! = Is set, and 0 is set to items on the right side thereof (items input in the second item input frame A2 of the variable registration screen G1). And each variable is connected by AND, for example.

  When four such variables are connected, X00 and X01 are connected by AND in the variable (X07). Similarly, X02 and X03 are connected by variable (X08), X04 and X05 are connected by variable (X09), X06 and X07 are connected by variable (X10), and X08 and X09 are connected by variable (X11). Then, as shown in the variable registration screen G1, when four variables are connected, the variable X07 (X00 and X01) and the variable X08 (X02 and X03) are connected by AND with the variable X12. Similarly, variable X13 connects variable X09 (X04 and X05) and variable X10 (X06 and X07), and variable X14 connects variable X11 (...) And variable X12 (. Further, the variable X15 (...) and the variable X14 (...) are connected by AND with the variable X15. In this way, all variables are connected by AND.

  In this case, a determination formula in which all the variables X00 to X06 are connected by AND is a condition, and it is determined that an abnormal state to be finally detected is determined and an alarm is output. When the information collected from the device-side controller 12 matches the final determination formula, the time until the monitoring-side controller 4 issues an alarm is set to 600 seconds. In FIG. 5, the variables X12 to X15 are not shown. Moreover, the combination of the variable may be a single item or a combination of a plurality of items.

  That is, when all of the variable X00 to the last variable X09 are connected by AND, an alarm condition is set, and if the judgment expression connected by AND matches the information collected from the device-side controller 12, the final It is determined that an abnormal state should be detected. Therefore, the monitoring controller 4 sends an email indicating the store name, the device 10 name, the channel name, etc. in which the communication abnormal state has occurred when all the devices 10 are simultaneously in a communication abnormal state and 600 seconds have passed. Is sent to the mobile phone of the maintenance company. As a result, a maintenance company prepares tools and parts necessary for repairing the device 10 in advance, and the store name with the store name recorded in the received e-mail is dealt with accurately and promptly. It will be.

  As described above, the monitoring controller 4 selects a single or a combination of a plurality of items from the information collected from the device-side controller 12 and the selected item or a combination of a plurality of items. Since there are means for setting an alarm condition and means for issuing an alarm when a selected item or a combination of a plurality of items matches the alarm condition, the monitoring controller 4 can collect any arbitrary items, Alternatively, alarm conditions can be arbitrarily set for these combinations, and an alarm (mail) can be issued from the monitoring controller 4 to the maintenance company's mobile phone when the alarm conditions are met.

  Thereby, in addition to the alarm function for the abnormality of each device 10 originally performed by the device-side controller 12, the abnormality prediction of the device 10 is performed when there is a sign that the device 10 becomes abnormal in the monitoring-side controller 4. Various abnormality monitoring forms can be freely constructed, such as by performing.

  Next, FIG. 6 shows a remote monitoring system 1 according to another embodiment of the present invention. In the second embodiment, a specific example of alarm transmission when an abnormality occurs in the operation load of the device 10 will be described. The remote monitoring system 1 has substantially the same configuration as the above-described embodiment. Hereinafter, different parts will be described. The same parts as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In this case, the alarm registration name is registered as showcase load detection, and the detection condition name is registered as blank (none). It is assumed that the determination formula is already set by inputting the determination symbol in the first item input frame A1, the second item input frame A2, and the determination input frame J1. The device 10, particularly the open showcase, has an open front, and such an open showcase is susceptible to the set temperature of the air conditioner (air conditioner). The temperature of the device 10 (showcase) is also detected using the temperature.

  In the alarm registration screen G3 displayed on the display device 14, information collected from the device-side controller 12 is displayed as shown in FIG. 6, and the abnormality prediction monitoring program displays the showcase information from a large number of collected information. It is determined whether or not an abnormality has occurred in the operating load. That is, the first determination formula is displayed in the first line (variable X00) on the top of the screen displayed on the alarm registration screen G3. In the first determination formula, TS_C indoor unit set temperature (cold) is set as an item (item input in the first item input frame A1 of the variable registration screen G1), => is set as a determination symbol, and an item (variable registration screen G1) 24 (meaning + 24 ° C.) is set in (the item input in the second item input frame A2). That is, the first determination formula (TS_C indoor unit set temperature (cold) => 24) means a determination formula for detecting whether the indoor set temperature of the air conditioner is + 24 ° C or higher as an alarm condition.

  Also, in the second line (variable X01) from the top of the alarm registration screen G3, the item (the item input in the first item input frame A1 of the variable registration screen G1) is Z2BIG14 refrigerated (2) the internal temperature, determination The symbol <=, the item (the item input in the second item input frame A2 of the variable registration screen G1), the item in the fifth and third lines (variable X02) (the first item input frame A1 of the variable registration screen G1) Input item) is Z3BIG15 refrigerated (3) Chamber temperature, judgment symbol is <=, item (item input in second item input frame A2 of variable registration screen G1), fifth and fourth lines (variable X03) The item (the item input in the first item input frame A1 of the variable registration screen G1) is Z4BIG16 refrigerated (4) the internal temperature, the determination symbol is <=, the item (the second item input frame A2 of the variable registration screen G1) Is set to 5).

  The above judgment formula will be briefly described. The variable X01 is Z2BIG14 refrigerated (2) the internal temperature <= 5, the variable X02 is Z3BIG15 refrigerated (3) the internal temperature <= 5, and the variable X03 is Z4BIG16 refrigerated (4). The internal temperature is set to <= 5. In other words, whether the set temperature in the showcase of G14, G15, and G16 is + 5 ° C. or less is set as an alarm condition in the determination formulas in the second to fourth lines of the alarm registration screen G3. This judgment formula is a judgment formula for detecting the influence on the energy saving effect due to the indoor set temperature of the air conditioner being higher than the set temperature inside the showcase of each showcase.

  That is, X00 and X01 are selected in the variable (X04), X02 and X03 are selected in the variable (X05), and a judgment formula in which all of them are connected by AND is set so that it can be judged as an abnormal state to be finally detected. Has been. Further, when the information collected from the device-side controller 12 matches the determination formula for determining the final alarm condition, the time until the monitoring-side controller 4 issues an alarm is set to 3600 seconds.
