Description

  The present invention relates to a plant monitoring apparatus that monitors the operational status of each device in each machine, the contents of abnormality, and the like.

  In a conventional plant monitoring device, individual signal information such as operation status of each device in each machine station scattered in a wide area, confirmation of abnormal contents, process value, mode status, etc. is transmitted to the center as it is, and this information is transmitted. The operator at the center monitored, and further, control from the center and on-site response instructions were given to patrolmen. This amount of information is very large, and it has been a heavy burden on the operator, for example, when an abnormality occurs, the operator determines whether or not to respond based on a plurality of individual signal information.

Therefore, it is conceivable to provide necessary data by processing a lot of signal information in a wide area in some meaningful way. For such a technique, for example, Patent Document 1 is publicly known.
JP 2003-223215 A

  In the above-mentioned Patent Document 1, the monitoring items of machine fields are hierarchized, and the state of objects in each hierarchy is determined and displayed at a plurality of operation levels. There is no concept of monitoring in the format, or using the processed data at all times.

  Therefore, monitoring of a multi-machine / multi-point device has been a heavy burden for the operator.

  The present invention has been made in view of such conventional points, and is capable of monitoring a multi-machine / multi-point device efficiently and monitoring the machine status at a glance. An object is to provide an apparatus.

In order to achieve the above object, a plant monitoring apparatus according to the present invention comprises:
An aggregation server that collects signals representing the status of the monitored object;
A determination unit that aggregates signals collected in the aggregation server based on a predetermined rule, and determines a situation in a machine facility or a function in the machine facility or equipment in the machine facility at a plurality of operation levels;
Based on the result determined by the determining means, there is provided a display means for displaying the status of the machine or functions in the machine or the equipment in the machine for a plurality of machines.

  According to the plant monitoring device of the present invention, it is possible to efficiently monitor a machine place, a function in the machine place, or equipment in the machine place, and reduce the burden on the operator. In addition, it is possible to efficiently cope with an abnormality that has occurred in the field.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following drawings, the same symbols indicate the same or corresponding parts.

  In FIG. 1, the structure of the plant monitoring apparatus which concerns on one Embodiment of this invention is shown.

  As shown in the figure, in the present embodiment, information on a plurality of aircraft 10 (10a, 10b,...) Such as A machine, B machine,... The data is sent to the wide-area monitoring center 20 via the communication line 12, the aggregation server 2 performs processing such as aggregation of the signals, the monitoring device 1 performs monitoring, and the monitoring device 1 operates and controls each machine station 10. Is realized.

  The flow of each signal is as follows. Signals indicating the status of the monitoring target such as a failure signal and a status signal in each machine 10 are transmitted from the machine gateway device 4 (4a, 4b,...) To the communication line 12 (12a, 12b,. And sent to the machine station monitoring server 3 (3a, 3b,...) Of the wide area monitoring center 20. Each machine 10 stores equipment of each company and handles different signal formats. Therefore, the machine gateway 4 unifies this signal format into a format handled by the wide-area monitoring center 20 or count value. Perform processing such as mutual conversion of data and engineering values.

  The signals sent to the machine monitoring server 3 process the signal information of each machine 10 here, but some signal information required by the aggregation server 2 is aggregated via the LAN 11 in the wide area monitoring center. Send to server 2. The aggregation server 2 has a function of determining whether or not the aggregated signal is established according to the rules for the aggregated signal held in the aggregation server 2 with respect to the signals sent from each machine monitoring server 3. Then, the information of these aggregated signals is sent to the monitoring device 1, and the operator can monitor each machine 10 with the aggregated information.

  As the communication line 12 includes information such as operation / operation information and data of the machine 10, a dedicated line is mainly assumed. However, by appropriately taking security measures (data encryption, password authentication, etc.) It is also possible to use a constant connection environment such as ADSL.

  On the other hand, the operation of each machine 10 from the monitoring device 1 is performed as follows.

  Normally, the monitoring device 1 performs monitoring using the displayed overall operation monitoring screen. From there, the machine operation monitoring screen and further the machine detail screen (the same screen as that monitored at each machine 10) are displayed. expand. This machine detail screen has the same function as the screen monitored at each machine 10. That is, when an operation command is output from this screen, each machine 10 is operated via the machine monitoring server 3, the communication line 12, and the machine gateway device 4.

  Next, an example of a mechanism of signal aggregation processing in the aggregation server 2 is shown in FIG.

  For example, in a certain water distribution station, it is classified into objects of functional units such as water reception, pressurization, direct delivery, and water delivery (see the left column in FIG. 2). Each object has four operation levels of “normal”, “monitoring required”, “response required”, and “urgent response” (see the central column in FIG. 2). For example, the meanings of these operation levels are as follows.

  “Normal”: When there is no special need for operator monitoring for normal operation, such as automatic operation or no major or minor failure.

“Needs monitoring”: Manual operation, process value change (no major or minor failure), etc., but no failure, but operator monitoring is required.

  “Necessary response”: A response is required, such as the occurrence of a minor failure, but continuous operation is possible. Or if there is a spare machine / spare system, etc., even if a major failure occurs as equipment, and the machine can be operated and operated continuously.

  “Immediate response”: When a major failure occurs and there is no spare machine or spare system, and the machine cannot be operated and operated continuously.

  Due to the classification of the operation level according to the degree of urgency of the response, an efficient response is possible when an abnormality or the like occurs in the aircraft 10.

  And it has each rule corresponding to these operation levels. These rules are realized by combining individual signal information of each machine 10 and various conditions (see the right column in FIG. 2). The conditions include not only logical rules such as “AND” and “OR”, but also rules such as determination of the duration of the digital signal being ON and determination of whether the analog value is within a certain range of values. Have. These conditions are prepared as component elements. In addition, individual signal information of each aircraft 10 is also stored in a signal database in the aggregation server 2. As a result, it is possible to create a rule that matches the actual operation. A method of editing this rule on the rule editing screen of the monitoring device 1 or a method of connecting and editing a rule setting terminal 21 provided separately from the monitoring device 1 can be considered. A method of editing by remote operation from an external terminal 24 for monitoring outside the wide-area monitoring center connected via the router 22 and the communication line 23 is also conceivable.

  An example of the overall operation monitoring screen in the monitoring device 1 is shown in FIG. The status of each machine 10 is displayed by dividing it into ranks (operation levels) of “normal”, “monitoring required”, “response required”, and “urgent response”. In the overall operation monitoring screen, as shown in FIG. 3, the statuses of a plurality of machine stations 10 are displayed in a color on the screen according to the operation level. It is divided into blocks for each area, such as “Eastern Block”, “A City West Block”, “B City Block”, “C Town Block”, and “D Town Block”. In this way, by displaying the statuses of all the machine stations 10 side by side on one screen, it is possible to confirm at a glance whether or not there is a failure or situation that should be dealt with quickly in each machine station 10. In addition, by dividing the display into blocks for each region, it is possible to check at a glance which block has water outage or water shortage, and which block has room, such as water supply facilities. When a lot of abnormalities occur at a block machine, you can find out which block is nearby or where you can afford water.

An example of the machine operation monitoring screen in the monitoring device 1 is shown in FIG. For example, in the overall operation monitoring screen shown in FIG. 3, this machine operation monitoring screen is expanded when the C water purification plant in the eastern block of city A is selected (when the cursor is clicked on the location of the C water purification plant). Is displayed. In this case, the screen may be completely switched to the machine operation monitoring screen and displayed, or when the C water purification plant in the eastern block of city A is selected, the entire operation monitoring screen is partially overlapped. Thus, it is possible to display the machine operation monitoring screen in a multi-window (then, it is possible to enlarge this screen and shift to the machine operation monitoring screen entirely). In addition, when a certain operation level in the operation level display at the upper left of the screen is selected (clicked with the cursor) on the overall operation monitoring screen shown in FIG. 3, the machine operation monitoring screen for the machine corresponding to that level is displayed. You can also For example, when “Urgent Response” is selected from the operation level display at the upper left of the screen, the machine station operation monitoring screen for the corresponding I water station is displayed. When there are a plurality of aircrafts corresponding to the selected operation level, all of the aircraft operation monitoring screens may be partially overlapped with the overall operation monitoring screen and displayed in a multi-window.

    In the above description, when a certain machine field or a certain operation level is manually selected in the overall operation monitoring screen shown in FIG. 3, it is expanded and displayed on the corresponding machine operation monitoring screen. In the overall operation monitoring screen shown in Fig. 3, when the operation level of a certain aircraft changes to a more urgent level and is displayed, it is automatically expanded and displayed on the corresponding aircraft operation monitoring screen. It is good as well.

  In the machine operation monitoring screen shown in FIG. 4, the functions or facilities in each machine 10 are divided into, for example, “power reception”, “water intake”, “filtration”, “water supply”, “water distribution”, “chemical injection”, and “system”. Then, the status of these functions or facilities is displayed by dividing them into ranks (operation levels) of “normal”, “monitoring required”, “response required”, and “urgent response”. Of these, the one with the highest response rank (the one with the highest response urgency) is displayed in the rank of the status of the machine field on the overall operation monitoring screen. For example, as shown in FIG. 4, in the machine operation monitoring screen of C water purification plant, the correspondence rank of “water supply” is the highest, and “response required”, so in the overall operation monitoring screen of FIG. Is displayed with a rank of “Needs Action”.

Then, on the machine operation monitoring screen shown in FIG. 4, when the “required response” part of the “water supply” line is selected (when the cursor is placed on the “required response” position of the “water supply” line and clicked), Accompanying information corresponding to is displayed. In the figure, as accompanying information, management information and contact information are displayed on the right side of the screen, and an alarm and status are displayed at the bottom of the screen. Note that a countermeasure may be displayed as accompanying information. In the alarm and status display, the resulting failure signal or status signal status is displayed. For example, as alarm information, the water supply equipment No. It is displayed that the two water pumps have a minor failure and the resulting signal is a DI (digital input) signal. When the cursor is placed on the “Status” tab at the bottom of the screen and clicked, status information is displayed as shown in FIG. No. 1 pump is in operation and the resulting signal is a DI (digital input) signal. 2 The pump is stopped, the resulting signal is a DI (digital input) signal,..., The water supply flow rate is 2.0 m ³ / s, and the resulting signal is an AI (analog input) signal. .

  In the above description, when the operation level of a certain function or facility is manually selected on the machine operation monitoring screen shown in FIG. 4, accompanying information corresponding to this is displayed. When the operation level of a certain function or facility is changed to an operation level equivalent to the operation level with the highest emergency level and is displayed on the machine operation monitoring screen (for example, from the display state shown in FIG. "Medication" changes to "Needs Action", which is equivalent to the operation level with the highest urgency level (ie "Need Action" for "Water Supply"), or more urgent When this is displayed after changing to a higher level (for example, when “medicine injection” or “water supply” is changed to “urgent response” from the display state shown in FIG. 4 and displayed) It automatically May be the corresponding accompanying information (especially the state of the fault signal or status signal resulting from its corresponding level) is displayed. Furthermore, in the overall operation monitoring screen shown in FIG. 3, when the operation level of a certain aircraft changes to an operation level equivalent to the operation level with the highest urgency level now and is displayed (for example, the display shown in FIG. 3) From the state, when the water treatment plant C changes to “Urgent Response”, which is the operational level equivalent to the “Urgent Response” of the I water station) Or, when it changes to a higher level of urgency and is displayed, it automatically expands and displays it on the corresponding machine operation monitoring screen and responds to the changed function or equipment operation level at that machine The accompanying information (particularly, the state of the failure signal or state signal resulting from the corresponding level) may be displayed.

  In addition, on the machine operation monitoring screen shown in FIG. 4, select the “Needs Action” part of the “Water Supply” line (by placing the cursor on the “Needs Action” position in the “Water Supply” line) and click on it. When the button display of “Aircraft details” is clicked (when the cursor is placed and clicked), for example, as shown in FIG. 6, the machine detail screen showing the detailed configuration of the local machine (the screen where each machine 10 is monitored and operated) To the same screen). In this case, the screen may be completely switched to and displayed on the machine detail screen, or partially overlapped with the machine operation monitoring screen to display the machine detail screen in a multi-window (then this It is also possible to enlarge the screen and move to the plane details screen entirely).

  In the above description, the machine detail screen is manually expanded and displayed. However, in the machine operation monitoring screen shown in FIG. 4, the operation level of a certain function or facility of the machine is set to a more urgent level. When this changes and is displayed, or when the operation level of a certain aircraft changes to a higher urgency level and is displayed on the overall operation monitoring screen shown in FIG. You may make it expand and display on the machine detail screen (for example, FIG. 6) corresponding to the changed function in the machine or the operation level of the facility.

  FIG. 6 shows the water supply facility of the C water purification plant as an example of the machine detail screen, in which devices such as two water pumps, two valves, and a flow meter are displayed as symbols.

  Then, as described above, the device can be operated or controlled manually or automatically from the displayed machine detail screen (local machine screen) shown in FIG. For example, when a device symbol shown on the screen is selected (right click with the cursor), a pull-down menu for operation or control is displayed. After selecting (clicking) one of them, the displayed OK is displayed. When the button is pressed (clicked), the operation command is output.

  It should be noted that by selecting (clicking) the button display of “machine operation” or “overall operation” in the upper right of the machine detail screen shown in FIG. 6, the machine operation monitoring screen of FIG. 4 or the overall operation of FIG. You can return to the monitoring screen.

  By unifying the screens of a plurality of machine stations 10 as shown in FIG. 3 and FIG. 4, which machine 10 has to be dealt with urgently first, and which function of the machine 10 has an abnormality that needs to be handled In addition, it is possible to provide the operator precisely and smoothly with what is caused by the abnormality of the function, and a smooth response at the site can be realized.

  Also, by providing the aggregation server 2 with a Web server function, it is possible to view these monitoring screens with a browser or issue an operation command from the monitoring external terminal 24 outside the wide area monitoring center 20. It becomes.

  In the examples so far, the aggregated signals are divided into four operation levels of “normal”, “monitoring required”, “response required”, and “urgent response”. It is also possible to change it to four or more stages according to the characteristics of the machine ground, the frequency of patrol crews, etc.
