Description

  The present invention relates to a remote monitoring system and an integrated management program for centrally managing sensor information collected by a plurality of controllers by a monitoring device via a network.

  In recent years, with the rapid spread of the Internet, the installation of IDC (Internet Data Center) has increased rapidly. In IDC, server computers and routers that generate high temperatures are arranged at high density in racks, etc., and server computers and routers may run out of control due to abnormal rise in room temperature. In order to prevent the occurrence of a failure, it is very important to monitor the room temperature and maintain an appropriate room temperature.

  Therefore, a remote monitoring system that measures environmental information such as temperature and humidity of a server room in which a server computer is installed and displays the measurement result on a monitoring terminal installed at a remote location has been conventionally provided (for example, Patent Document 1). FIG. 8 is a schematic configuration diagram of a remote monitoring system, in which a temperature sensor 1a that detects the ambient temperature, a humidity sensor 1b that detects the ambient humidity, and power that detects the amount of power used by electrical equipment such as a server computer and a router. The sensor 1c, a plurality of controllers 10 that collect and store the measurement results of the sensors 1a to 1c, and the measurement values accumulated by the controllers 10 are connected to the plurality of controllers 10 via the LAN 40 and the network NT. The monitoring device 20 is centrally managed.

Here, each controller 10 periodically collects the measured values of the sensors 1a to 1c, and when the measured value exceeds a predetermined threshold value for each sensor, an abnormal state occurrence state (abnormal state) (E.g., information such as the name, installation location, detection time, etc.) of the sensor that has detected the error is transmitted to the monitoring device 20. When the monitoring device 20 receives the e-mail transmitted from each controller 10, the monitoring device 20 displays a list of all abnormal states detected by the sensors 1a to 1c on the display monitor screen. At the same time, the administrator knew the occurrence of an abnormal condition.

  Embodiments of the present invention will be described with reference to the drawings. The remote monitoring system according to the present embodiment is provided in, for example, a plurality of buildings, and environmental information such as temperature and humidity in a monitoring area such as a server room in which a large number of server computers and routers are respectively installed. As shown in FIG. 1, this system includes a plurality of sensors 1, a plurality of controllers 10, and a monitoring device 20 as main components. ing. In FIG. 1, only one sensor 1 and one controller 10 are shown for simplification of illustration, but actually, a plurality of sensors 1 and controllers 10 are provided.

  The sensor 1 detects environmental information such as the temperature and humidity of the indoor space in a monitoring area such as a server room where a large number of server computers are installed.

  The controller 10 is composed of, for example, an on-board microcomputer, and collects measurement results from the corresponding sensors 1 and, when the measurement results exceed a predetermined threshold value for each sensor, an abnormal state occurrence state Is transmitted to the monitoring apparatus 20 via a network NT such as an intranet or the Internet. Here, as alarm information transmitted from the controller 10 to the monitoring device 20, for example, the sensor name individually assigned to the sensor 1 that has detected the abnormal state, and the type of environmental information detected by the sensor 1 (for example, temperature or Humidity), the measurement result, and the time when the abnormal state was detected.

  The monitoring device 20 is a computer connected to a network, and an integrated management program is stored in an external storage device (not shown) of this computer. FIG. 1 is a block diagram of a monitoring device 20 that executes an integrated management program, and includes a collection system block 21 that executes collection system processing and a display system block 22 that executes display system processing. The collection block 21 receives a data collection process 23 (sensor information collection means) for collecting measurement data from the controller 10 via the network NT using the SNMP protocol, and the controller 10 in response to an SNMP trap request from the controller 10. Event receiving process 24 (alarm information receiving means) that collects event information (measured values and alarm information at the time of state change) via network NT, and data (measurement data and event information) collected by both processes 23 and 24 ) Is stored in the database 25 (storage means).

  The display system block 22 creates a screen (for example, HTML format) that can be viewed by a general-purpose browser based on the data read from the database 25, and registers the data in the data display processing / registered in the Web server 27 described later. A registration process 26 (screen creation means), a web server 27 on which screen data created by the data display processing / registration process 26 is registered, and installed on the web terminal and registered in the web server 27 using the HTTP protocol. The browser 28 (display means) displays the designated screen on the monitor screen of a display monitor (not shown) by reading the screen.

  Next, the operation of the remote monitoring system will be described with reference to the drawings, focusing on the operation of the integrated monitoring program. First, the operation of the collection system block 21 of the monitoring device 20 will be described. Each controller 10 is assigned an individual address (IP address), and communication is performed between the collection system block 21 of the monitoring apparatus 20 and the controller 10 using the SNMP protocol as described above.

Normally (except when an alarm is generated), a data request command for requesting sensor information is sequentially transmitted to a plurality of controllers 10 at predetermined sampling intervals by the data collection process 23 of the monitoring device 20 (a in FIG. 1). When the sensor information of the sensor 1 is transmitted from the controller 10 in response to the data request command, the data collection process 23 receives the sensor information, attaches the data of the reception time to the received sensor information data, Save in the database 25 (C in FIG. 1)
When the controller 10 detects an abnormal state separately from the normal data collection process, the controller 10 transmits alarm information indicating the occurrence state of the abnormal state to the monitoring device 20. That is, the controller 10 captures the measurement result of the sensor 1 at a predetermined interval shorter than the above-described sampling interval, and when the measurement result exceeds a threshold value predetermined for each sensor, a TRAP command is sent to the monitoring device 20. This is transmitted to notify the occurrence of an abnormal state (event) (D in FIG. 1). In the monitoring device 20, when the event reception process 24 receives the TRAP command transmitted from the controller 10 via the network NT, it transmits a data request command to the controller 10 that has transmitted the TRAP command (e in FIG. 1). Data (that is, alarm information) transmitted from the controller 10 in response to this data request command is received (FIG. 1), and the received alarm information is attached to the received alarm information and stored in the database 25 ( 1).

  Next, the operation of the display system block 22 of the monitoring device 20 will be described. In the data display processing / registration process 26, sensor information and alarm information stored in the database 25 are read at predetermined intervals, processed into necessary data items, and again classified into data for each sensor according to a new schema. 25, the alarm information screen for displaying the alarm information is created in the HTML format and registered in the Web server 27. When the URL of the alarm information screen registered in the web server 27 is designated by the browser 28, the HTML file of the designated URL is transmitted from the web server 27 to the web terminal and displayed on the monitor screen of the display monitor by the browser 28. It is.

  FIG. 2 is an example diagram of the alarm information screen G1, and the display contents of the alarm information will be described with reference to this figure. A menu display part g1 for displaying a menu is displayed on the left side of the screen, and an information display / input part g2 for displaying information selected from the menu or inputting data is displayed on the right side. The other screens to be described have the same screen configuration.

  In the menu display portion g1, a plurality of selection buttons M1 to M8 for selecting various menus are displayed side by side. For example, the cursor is moved to the selection button M1 by a mouse operation to perform a click operation (selection operation). Is performed, an alarm information screen G1 shown in FIG. 2 is displayed.

  In the information display / input part g2 of the alarm information screen G1, a title bar T1 indicating the title of the screen (“alarm information”) is displayed on the upper side, and the alarm information received from the controller 10 is displayed below the title bar T1. A table H1 displayed as a list for each sensor 1 is displayed.

  In the first row of Table 1, the item names of the respective items are displayed side by side, and in the illustrated example, “type”, “date / time”, “first occurrence date / time”, “event”, “sensor”, “Building”, “Floor”, “Controller”, “Countermeasure”, and “Delete” items are displayed.

  Here, in the “type” item, information on the abnormal state (event) that has occurred is displayed as a symbol (icon) I1, and the display color is changed to green when normal and red when abnormal. . In FIG. 2, the difference in display color is indicated by the shape of symbol I1, indicating that the double circle is displayed in green and the single circle is displayed in red.

  The date and time when the measurement state of the sensor 1 last changed is displayed in the “date and time” item, and the date and time when alarm information is received for the first time is displayed in the “first occurrence date and time” item.

  In the “event” item, the cause (for example, “temperature”, “humidity”, etc.) of the generated abnormal state (event) is displayed, and the measured value is displayed in parentheses. Since the measured values are displayed in green when normal and red when abnormal, the abnormal state can be easily distinguished from the difference in display color.

  In the “sensor” item, a sensor name individually assigned to the sensor 1 that has detected an abnormal state is displayed. For example, the cursor is moved to the position of the sensor name by a mouse operation, and a click operation (selection operation) is performed. When the browser 28 designates the URL of the map display screen (location screen) indicating the installation location of the sensor 1, the HTML file of the designated URL is transmitted from the web server 27 to the web terminal, and the browser 28 displays the display monitor. A map display screen G3 (see FIG. 4) is displayed on the screen.

  In the “building” and “floor” items, the building name and the floor name of the building where the sensor 1 is installed are respectively displayed. In the display item “controller”, a controller name individually assigned to the controller 10 to which the sensor 1 is connected is displayed.

  In the “Countermeasure status” item, if a countermeasure is registered on this alarm information on the countermeasure registration screen G2 (see FIG. 3) described later, the text “Now working” is displayed. Is displayed with “unsupported” characters. If there is at least one “unsupported” display in the “Countermeasure status” item, “Unsupported sensor” is displayed in red in the upper left of the table H1.

  Here, when a click operation (selection operation) is performed with the cursor placed on the character “unmeasured” by a mouse operation, the URL of the countermeasure registration screen G2 for registering the corresponding action is specified by the browser 28, and the specified URL The HTML file is transmitted from the Web server 27 to the Web terminal, and the countermeasure registration screen G2 is displayed on the screen of the display monitor by the browser 28. Then, after registering the countermeasure on this countermeasure registration screen G2, when returning to the original alarm information screen, the data display processing / registration process 26 switches the display of “countermeasure item” to the characters “in response”.

  When the mouse is operated and a click operation is performed with the cursor placed on the character “Supporting”, the browser 28 specifies the URL of the response status screen that displays the registered response action, and the HTML of the specified URL is displayed. The file is transmitted from the Web server 27 to the Web terminal, and the screen of the display monitor is switched to the corresponding status screen by the browser 28.

  In the “delete” item, a delete button for deleting the display of alarm information is displayed for each individual alarm information. When the mouse is operated to move the cursor to the delete button B1 and a click operation is performed, data display processing / The registration process 26 creates a screen in which the abnormal state of the sensor 1 is deleted from the table H1 and displays it on the monitor screen by the browser 28. Then, the response registered in the countermeasure registration screen G2 for the abnormal state of the sensor 1 is displayed. A sub-screen (not shown) for selecting whether or not to save the contents of the treatment is created and displayed on the screen so as to be superimposed. When the save processing is selected on this sub-screen, the content of the corresponding treatment is stored in a database in CSV format, for example. Save to 5.

  Here, the data display processing / registration process 26 creates the above-described alarm information screen G1 based on the alarm information registered in the database 25, and a plurality of pieces of alarm information from the same sensor 1 are stored in the database 25. If so, the alarm information of the sensor 1 displayed on the alarm information screen G1 is updated, and the alarm information screen G1 is updated so that only the contents of the latest abnormal state are displayed. Therefore, even when alarm information is output many times from the same sensor 1, only the latest information for that sensor 1 is displayed in Table 1, and a plurality of alarm information of the same sensor is displayed. Therefore, it is possible to prevent the alarm information from other sensors from being buried therein and the monitoring person from overlooking important alarm information. When new alarm information is input while the alarm information screen G1 is being displayed, the fact that additional alarm information has occurred may be displayed on a sub-screen or notified by voice.

  When an operation of selecting the “unsupported” character displayed in the “Countermeasure status” item on the alarm information screen G1 is performed, the URL of the countermeasure registration screen G2 is designated by the browser 28, and the HTML of the designated URL is specified. The file is transmitted from the web server 27 to the web terminal, and the countermeasure registration screen G2 for registering the countermeasure is displayed on the display monitor screen by the browser 28 (see FIG. 3). This screen G2 is created by the data display processing / registration process 26, and a table H2 displaying information of the sensor 1 for registering the corresponding treatment is displayed on the upper side of the screen G2. In this table H2, the “building name” and “floor name” of the building where the sensor 1 to be registered is installed, the “controller name” to which the sensor 1 is connected, and the “sensor name” of the sensor 1 Items such as “state” indicating the cause of the abnormal state (event) that has occurred and the measured value are displayed.

  An input table H3 for registering corresponding measures is displayed below the table H2, and a table H4 showing registered measures is displayed below the input table H3. In FIG. 3, there is only one registered table H4. However, when a plurality of corresponding measures are registered (up to a maximum of five in this embodiment), a plurality of registered corresponding measures are indicated. The table H4 may be displayed in chronological order.

  The input table H3 is provided with input columns C1 to C3 for inputting the contents of “date and time”, “responder”, and “comment”. For example, after the cursor is moved to each of the input columns C1 to C3 by a mouse operation After inputting the date and time when the corresponding action was performed using an input device such as a keyboard, the name of the person who performed the corresponding action, and the content of the corresponding action, the position of the cursor on the registration button B3 on the lower side of the screen When a click operation (selection operation) is performed together, the input content is sent to the data display processing / registration process 26 and stored in the database 25 by the data display processing / registration process 26, and alarm information is displayed by the browser 28. The URL of screen G1 is specified, the screen is switched to the original alarm information screen G1, and the display of “Countermeasure status” switches from “Not supported” to “Supported” Waru. On the other hand, if the user clicks the cancel button B4 on the lower side of the screen with a mouse operation and performs a click operation (selection operation), the input content is not saved and the URL of the alarm information screen G1 is designated by the browser 28. Then, the screen is switched to the original alarm information screen G1.

  As described above, the data display processing / registration process 26 as the response status registration means performs the response action for the abnormal state indicated by each alarm information in correspondence with each alarm information displayed on the alarm information screen G1. Since the response status information including the content of the response person and the response action is registered and the screen (measure registration screen G2) for displaying the registered response status is created, a plurality of persons in charge are monitored alternately. Even in this case, it is possible to easily confirm the content of the countermeasure taken by the previous person in charge, and it is possible to reliably and easily transfer information between the persons in charge. In addition, in order to prevent a serious failure such as a communication failure from occurring when an abnormality occurs, an emergency response measure is taken first to prevent a serious failure before a permanent response measure is taken. However, in the data display processing / registration process 26, the response status information indicating the contents of all the countermeasures implemented for each alarm information is displayed in chronological order. This makes it possible to easily check the corresponding measures and to transfer information more reliably when the person in charge changes.

  In addition, in the above-described alarm information screen G1, when the click operation (selection operation) is performed by moving the cursor to the character of “sensor name” by the mouse operation, the browser 28 specifies the URL of the map display screen. The HTML file having the URL is transmitted from the Web server 27 to the Web terminal, and the browser 28 displays the map display screen G3 (see FIG. 4) on the display monitor screen. The map display screen G3 is created by the data display processing / registration process 26, and the controller 10 and the controller 10 registered on the controller registration screen G5 and the sensor registration screen G6 described later are registered in the floor diagram registered on the floor registration screen G4 described later. A map is created by overlapping symbols S1 to S3 of sensor 1 (temperature sensor 1a and humidity sensor 1b). Here, the icons of the sensor 1 and the controller 10 are displayed at corresponding positions on the map using the X seat and Y coordinates of the installation positions input on the registration screens G5 and G6 described later. The installation positions of the sensor 1 and the controller 10 can be easily grasped from the display on the map display screen G3. In FIG. 4, the installation position of the controller 10 is indicated by a blue square symbol S1, the installation position of the temperature sensor 1a is indicated by a circular symbol S2, and the installation position of the humidity sensor 1b is indicated by a triangular symbol S3.

  In addition, among the sensors 1a and 1b, the symbols S2 and S3 of the sensors that have not detected the abnormal state are displayed in green, and the symbols S2 ′ and S3 ′ of the sensors that have detected the abnormal state are displayed in red. The sizes of the symbols S2 ′ and S3 ′ are changed, and the symbols S2 ′ and S3 ′ corresponding to the sensor that has detected the abnormal state can be easily distinguished visually by changing the display color, size, or shape. I have to. Further, in the map display screen G3 shown in FIG. 4, when the person in charge wants to know the sensor information (for example, the sensor name and the current measured value) related to the sensor 1 displayed on the map, the person in charge uses the input device such as a mouse. When the cursor is placed on the symbols S2 and S3 of the sensor 1, the data display processing / registration process 26 reads the sensor information of the sensor 1a or 1b corresponding to the symbol at the cursor position from the database 25 and displays the information. A text box TB1 is created, and this text box TB1 is displayed superimposed on the cursor position on the map display screen G3. Information on a desired sensor can be easily read from the display of the text box TB1. Further, when the person in charge superimposes the cursor on the symbols S2 and S3 of the desired sensor 1 using an input device such as a mouse and performs a click operation (selection operation), the Web server of the controller 10 to which the sensor 1 is connected. And the Web screen is displayed in a new window.
