(Embodiment 1)
As shown in FIG. 1, the remote monitoring system of the present embodiment includes a local device 10 to be monitored and controlled and controllers 20A and 20B installed for each monitoring area (hereinafter simply referred to as a controller unless they are particularly distinguished from each other). 20) and a browser terminal 30 owned by the user. Hereinafter, as an example, two monitoring areas of the building A in which the controller 20A is installed and the building B in which the controller 20B is installed will be described as objects to be monitored. The system can monitor a plurality of monitoring areas.

  As shown in FIG. 2, the local device 10 includes an input / output terminal 11 that performs input / output control of a facility device 41 such as a power device, a power device, and an air conditioner, and an output terminal 12 that supplies dimming power to the lighting fixture 42. And a weighing terminal 13 that monitors the weighing device 43 that measures the amount of power and the like. Further, in the example of FIG. 2, the disaster prevention / crime prevention terminal device 14 that sucks up information from a separate crime prevention / disaster prevention system 44, the wall switch 15 that operates the lighting equipment connected to the output terminal device 12 to turn on / off, the output It includes an annunciator 16 that is a setting input device for managing a number of lighting fixtures other than the lighting fixtures connected to the terminal device 12 and setting a lighting / extinguishing pattern, an alarm unit 17 for expansion, and the like. These various local devices 10 (11 to 17) are used for remote control type building management systems and remote monitoring type home security systems. In short, monitoring information (at least one of various detection states and various controlled states) is stored. It is a changing device.

  As shown in FIG. 3, the controller 20 is configured by a computer system including a central processing unit 21 and a storage device 22. The central processing unit 21 monitors the local device 10 by communicating with the above-described local device 10 (11 to 17) to be monitored and controlled, for example, in the polling / selecting method, by the transmission signal transmission / reception unit 23 via the transmission line 5. It has a function of a monitoring control unit 24 that collects information and controls the local device 10. Further, in the central processing unit 21, a Web server unit 25 and a CGI server unit 26, which will be described later, are constructed by executing corresponding software.

  The browser terminal 30 is a client machine for the controller 20 as a server, and is a personal computer (hereinafter referred to as a personal computer) including a communication unit 31 (see FIG. 1) that can be connected to the controller 20 via a network such as an intranet or the Internet. It consists of). Therefore, a delivery request can be sent to the controller 20 from anywhere in the world by starting a Web browser to the controller 20 with, for example, a Java (registered trademark) virtual machine. Note that a mobile communication browser terminal 30 ′ (see FIG. 2) using a mobile communication network may be used.

  In response to this, the controller 20 is configured with the above-described Web server unit 25 and CGI server unit 26 by mounting corresponding software such as HTTPd (Hyper Text Transfer Protocol daemon) and CGI (Common Gateway Interface). The CGI server unit 26 acquires monitoring information from the local device 10 through the monitoring control unit 24, and the Web server unit 25 generates a monitoring screen including monitoring information in an HTML (Hyper Text Markup Language) format. The result (monitoring screen) is distributed from the Web server unit 25 to the browser terminal 30 via the communication unit 27 corresponding to Ethernet (registered trademark) and the communication line 6. Accordingly, the browser terminal 30 that has made the distribution request can display a monitoring screen including the monitoring information of the local device 10 on the screen of the display 32 (see FIG. 1) provided in the terminal body. Although the controller 20 is connected to the communication line 6 via the router 7 (see FIG. 1), the router 7 is not shown in FIG.

  By the way, the browser terminal 30 has not only the basic function for displaying the monitoring screen as described above but also a launcher function described below.

  That is, as shown in FIG. 1, the browser terminal 30 according to the present embodiment targets a plurality of controllers 20 arranged in a plurality of monitoring areas from the plurality of controllers 20 through the communication unit 31, and A collecting means 33 for collecting monitoring information is provided in the terminal body. The collection unit 33 transmits a data request to each of the controllers 20A and 20B using the identifiers (addresses) of the controllers 20A and 20B registered in advance in a holding unit (not shown) provided in the browser terminal 30. By monitoring the data request, the monitoring information of specific items is collected from the controller 20. The collection unit 33 collects monitoring information from each controller 20 at a specified time interval (for example, a cycle of 10 seconds), and updates the monitoring information to the monitoring information after the change if there is a change since the previous acquisition. Here, the monitoring information of all the local devices 10 may be collected by the collecting means 33, but in this embodiment, only the presence or absence of an alarm generated in the crime prevention / disaster prevention system 44 (see FIG. 2) is collected. It is assumed that the monitoring information collected by 33.

  Further, the browser terminal 30 generates a collective management screen 50 including the monitoring information collected by the collecting means 33 in the same screen as shown in FIG. 4, and collective management for displaying the collective management screen 50 on the display unit 32. Means 34 is provided in the terminal body. Here, the collective management unit 34 is activated when a predetermined operation is performed on the browser terminal 30 (for example, a predetermined icon is selected on the screen of the browser terminal 30). It is configured to start upon receipt of a start message generated when the collective management means 34 is started. The collective management screen 50 is divided into two regions, the upper part and the lower part, and the monitoring information (in this case, whether there is an alarm) acquired from each controller 20A, 20B is displayed on the upper part by the iconization function of the collective management means 34. Displayed as representative icons 51A and 51B associated with each 20B (hereinafter simply referred to as the representative icon 51 when they are not particularly distinguished). In the example of FIG. 4, since eight representative icons 51 are displayed, up to eight controllers (that is, eight monitoring areas) 20 can be handled.

  As shown in FIG. 5, the representative icon 51 displays whether or not an alarm has been generated and whether or not an unconfirmed alarm has been generated depending on its lighting state (the shaded area in the drawing indicates a currently lit area). Here, an unconfirmed alarm is one that has already been recovered, but has not yet been confirmed on the monitoring screen by accessing the corresponding controller 20 after the alarm has occurred. If collection of monitoring information fails due to a communication error between the browser terminal 30 and the controller 20, the collecting unit 33 retries collecting monitoring information for a preset number of retries, and succeeds during this time. If not, “Difference” is displayed in the corresponding representative icon 51.

  In addition, when a new alarm is generated while the collective management screen 50 is displayed, that is, when a change occurs in the displayed monitoring information, a buzzer or a speaker built in the browser terminal 30 is sounded. The browser terminal 30 is provided with a notification means 35 that generates a warning notification sound. As a result, when a new alarm is generated, the alarm is displayed with the representative icon 51 and a notification sound is generated. Therefore, even if the user does not always look at the screen of the browser terminal 30, the new alarm is displayed. Can be notified to the user. The notification unit 35 generates a notification sound even when a communication abnormality occurs.

  Here, in this embodiment, the alarm level is determined for each group of 10 local devices, and when performing notification using the notification sound, priority is given to the one with the higher alarm level. In addition, when the ringing time of the alarm sound with a high alarm level ends and the ringing time of the alarm sound with a low alarm level remains at the end time, the process of starting the alarm ringing of the alarm sound with a low alarm level Is supposed to do. Here, a heavy alarm level, a medium alarm level, a light alarm level, and a communication abnormality are assigned in order from the highest importance level, and the assignment can be arbitrarily set by the user. And the distinctiveness is given by changing the tone color of a notification sound for every warning level, and the effect which urges a user's attention is heightened. Note that the ringing time of the notification sound is set to an arbitrary length, but may be continuously ringed until the alarm is restored.

  In the lower part of the collective management screen 50, a change history of monitoring information of a predetermined number (here, 5) from the latest is displayed as a list of alarms (management list) 52 in time series. Here, the order in which the monitoring information is displayed is determined based on the time when the browser terminal 30 actually acquires the monitoring information. In the alarm list 52, relatively detailed information such as the alarm occurrence date and time, the alarm generation controller 20 and the name of the monitoring area (identification information), and the alarm status are displayed for each line. Further, by making the character color different between the occurrence of an alarm and after the restoration (for example, red during the occurrence of the alarm and black after the restoration), information relating to the alarm that is occurring is made conspicuous. The alarm list 52 is generated by the list function of the collective management unit 34. When the enlarged icon 53 provided in the collective management screen 50 is selected (clicked) by the pointing device of the browser terminal 30, the display size of the representative icon 51 is reduced and the number of alarms displayed in the alarm list 52 is reduced. It is possible to increase (for example, 20 cases).

  Here, the browser terminal 30 is provided with a link means 36 for establishing a link between each representative icon 51 and the monitoring screen generated by each controller 20. Thus, when the user selects (clicks) one of the representative icons 51 with the pointing device of the browser terminal 30, the browser terminal 30 starts communication with the controller 20 that is the transmission source of the monitoring information indicated by the representative icon 51. Then, the HTML format data distributed from the controller 20 is acquired and the monitoring screen is displayed.

  By the way, in this embodiment, in order to ensure security, when the browser terminal 30 communicates with the controller 20 to display the monitoring screen, the controller is only used when the authorized user is recognized by the authentication process using a predetermined account. 20 login is permitted. Therefore, when displaying the monitoring screens of a plurality of controllers 20, it is necessary to log in for each controller 20. Once logged in, it is not necessary to log in again unless the monitoring screen is closed. However, in order to monitor the monitoring screens of the plurality of controllers 20, it is necessary to open a plurality of monitoring screens. Becomes complicated.

  Therefore, a login function for automatically logging into the controller 20 when the representative icon 51 is selected is added to the link means 36. Specifically, a user name and password as an account necessary for login are registered in the browser terminal 30 in advance, and the login function performs login using these registered user name and password. Thus, the controller 20 authenticates the user name and password, and if it is determined that the user name and password match the regular one, the HTML format data corresponding to the monitoring screen is distributed to the browser terminal 30. As a result, the user can view the monitoring screen by simply clicking the representative icon 51 without entering the user name and password when logging in.

  If the browser terminal 30 is left unattended while logged in to the monitoring screen, such as when the user leaves the seat, there is a possibility that the monitoring screen is illegally monitored or operated by a third party other than the user. There is. Therefore, in this embodiment, a logout function for automatically logging out from the monitoring screen of the controller 20 is added to the link means 36 if the operation of the browser terminal 30 by the user is not detected for a predetermined logout time or longer. Thereby, even if the browser terminal 30 that has been logged in is left unattended, unauthorized monitoring / operation of the monitoring screen by a third party can be avoided, and security can be improved. The logout time can be set arbitrarily.

  Next, the operation of the remote monitoring system of this embodiment will be described with reference to the sequence diagram of FIG. 6 and the flowchart of FIG.

  In the browser terminal 30, when the collective management unit 34 is activated, the collective management screen 50 is displayed, and the collection unit 33 is activated in conjunction with the activation message to acquire monitoring information from each of the controllers 20A and 20B (S11, S21) is started. At this time, the collection unit 33 acquires the monitoring information (in this case, whether there is an alarm) from each controller 20A, 20B by sending a data request to the target controllers 20A, 20B and returning the data request. Note that the monitoring information acquisition process from each controller 20A, 20B is executed in parallel by individual threads, thereby collecting monitoring information in a short time while targeting a plurality of controllers 20A, 20B. can do.

  When the communication between the collecting unit 33 and each of the controllers 20A and 20B is normally established (S12: No, S22: No), and the collecting unit 33 acquires monitoring information “alarmed” from each of the controllers 20A and 20B. (S13: Yes, S23: Yes), the information “alarm is present” is transferred from the collection means 33 to the collective management means 34. In response to this, the collective management unit 34 notifies “alarm exists” by the representative icons 51A and 51B corresponding to the controllers 20A and 20B, respectively (S14 and S24). Here, when a warning is newly generated and the display state of the representative icon 51 is changed (S15: Yes, S25: Yes), the notification unit 35 sounds the buzzer of the browser terminal 30 to generate a notification sound. Output (S16, S26). In addition, the collective management unit 34 receives the notification “alarm is present” from the collection unit 33 and updates the alarm list 52 to the latest state.

  In addition, when a communication abnormality occurs between the collecting unit 33 and each of the controllers 20A and 20B and monitoring information from each of the controllers 20A and 20B cannot be acquired (S12: Yes, S22: Yes), the collecting unit 33 collectively Information "communication error" is transmitted to the management means 34, and the communication abnormality is notified by the representative icons 51A and 51B corresponding to the controllers 20A and 20B, respectively (S17, S27). At this time, a notification sound is also generated by the notification means 35.

  When processing for ending the display of the collective management screen 50 is performed in the browser terminal 30, the collective management unit 34 starts its own termination process and notifies the collection unit 33 of an end message. The means 33 ends the monitoring information acquisition process from the controller 20. However, when the collection unit 33 receives an end message in the middle of a series of processing (data request transmission and monitoring information reception) for all the target controllers 20A and 20B, the collection unit 33 does not complete until the series of processing is completed. It is assumed that the operation waits and then ends.

  According to the remote monitoring system described above, the collective management screen 50 can simultaneously display monitoring information (here, whether there is an alarm) of the local devices 10 provided in a plurality of monitoring areas on the same screen. That is, the user can confirm the information of the local device 10 managed by the controller 20A of the building A and the information of the local device 10 managed by the controller 20B of the building B at a time. Therefore, even when a plurality of monitoring areas are to be monitored, the user can monitor the plurality of monitoring areas without frequently switching the monitoring screen displayed on the browser terminal 30.

  Further, when the user selects the representative icon 51 on the collective management screen 50, the browser terminal 30 automatically accesses the controller 20 corresponding to the representative icon 51, and displays the monitoring screen generated by the controller 20. Can be displayed. Therefore, for example, when one representative icon 51 indicates the occurrence of an alarm, the user displays the monitoring screen of the controller 20 that is the transmission source of the monitoring information on the browser terminal 30 to display the details of the alarm. It can be easily confirmed.

  By the way, the launcher function of the browser terminal 30 described above can be used by installing a dedicated program on a general-purpose personal computer or the like used as the browser terminal 30. That is, by installing a dedicated program on a personal computer, each means such as the collecting means 33, the collective management means 34, the linking means 36, and the notification means 35 is realized by the personal computer. Therefore, if a remote monitoring system has already been established for a plurality of monitoring areas, the user simply installs the program on a general-purpose personal computer or the like, and uses the existing remote monitoring system to collectively manage the plurality of monitoring areas. Is possible. A dedicated terminal device in which such a program is installed from the beginning may be used as the browser terminal 30.

(Embodiment 2)
The remote monitoring system of the present embodiment is a history collecting means (not shown) for collecting past data from the controllers 20A and 20B based on a plurality of monitoring information collected from the local device 10 by each controller 20A and 20B within a predetermined period. Is different from the remote monitoring system of the first embodiment in that it is added to the browser terminal 30. In the present embodiment, the past data is the weighing data obtained by the weighing terminal 13. However, the present invention is not limited to this example, and various data such as an alarm occurrence history can be used as the past data. Here, the measuring terminal 13 is connected to a measuring device for measuring the amount of electricity, the amount of water used, etc. or measuring the temperature, etc., and the results obtained by each measuring device (the meter reading result, the measurement result) are used as measurement data. It is sent to the controller 20.

  The history collecting means is activated upon receipt of the activation message when the collective management means 34 is activated in the browser terminal 30 and automatically collects past data from the controller 20 at the activation. Specifically, the history collecting means acquires past data in CSV (Comma Separated Values) format from the controller 20 by sending a past data request to the target controller 20 and returning it to the past data request. To do. If past data collection fails due to a communication error between the browser terminal 30 and the controller 20, the history collection unit retries collecting past data for a preset number of retries, and succeeds during this time. If not, an error message is displayed on the display 32.

  The browser terminal 30 includes output means (not shown) that outputs past data collected from the controller 20 in a predetermined format on the screen of the display 32. The past data is displayed for each of the controllers 20A and 20B, and the display target controllers 20A and 20B are switched by a simple operation of the browser terminal 30. Here, the output means outputs past data in the form of a report such as daily report, monthly report, annual report, centralized meter reading, simple billing. The centralized meter reading here is a format that shows the respective weighing data for each weighing terminal 13 for the current month, the previous month, and the current day, and the simple billing is a format that shows a fee that is simply obtained from a billing object such as an electric energy. is there. Furthermore, when a printer (not shown) is connected to the browser terminal 30, it is possible to print past data in a form format by the output means. The past data may be printed by a user operation on the browser terminal 30 or may be automatically performed at a preset date and time.

  According to the configuration described above, since past data within a predetermined period can be collected retroactively from the activation time of the browser terminal 30 and displayed in a form format, the monitoring information before the activation of the browser terminal 30 is also missing. Display without any problem. Therefore, even when the functions of the history collection unit and the output unit described above are added to the browser terminal 30 of the existing remote monitoring system, the past monitoring information held by the controller 20 can be automatically supplemented. it can.

  By the way, as another example of the present embodiment, it is conceivable that the history collecting means periodically collects past data. The period of collecting past data is, for example, one day. In this case, the browser terminal 30 is automatically activated at a predetermined time, and past data is collected from the controller 20 by the history collecting means. Thereby, regardless of whether or not the browser terminal 30 is activated, there is an advantage that the past data can be periodically updated to the latest information.

  Other configurations and functions are the same as those of the first embodiment.

  In each of the above-described embodiments, an example is shown in which all the controllers 20A and 20B that can display a monitoring screen on the browser terminal 30 are targets of collection of monitoring information and past data by the browser terminal 30. However, the controller 20 may be arbitrarily set as a monitoring information collection target or past data collection target.
