Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to alarm guidance for plant operation used in various plants such as water and sewage plants, industrial plants such as steel plants, district heating and cooling plants, heat source plants for each building, and power plants. It concerns the device.

[0002]

2. Description of the Related Art The operating state of plant equipment is usually monitored by a plant monitoring and control device. When an abnormality or a sign of abnormality is found, an alarm is issued immediately, and an operator can take an appropriate action according to the content of the abnormality. Actions can be taken. In this case, guidance information is also displayed on the screen of the plant monitoring and control device together with the abnormality occurrence information.
It is a simple one in which one Japanese message is assigned to at most one TAG information (process data with a number called a TAG number).

[0003]

However, in plant equipment, since an abnormality occurring at a certain location affects many locations, the operator has to perform complicated operations and confirmations on many devices in a predetermined manner. Must be performed promptly according to the procedure. However, as described above, the guidance function in the conventional plant monitoring and control device has a small amount of information as guidance information, and the content transmitted to the operator is only simple operation content and abstract precautions. Usually, sufficient information cannot be conveyed to the operator, and guidance cannot be given as to what will happen next. Therefore, a certain amount of experience and years are required to perform a monitoring operation properly in a conventional plant monitoring and control device, and a veteran operator is usually in charge of the monitoring operation.

[0004] However, in recent years, rationalization has been promoted in plant equipment by unmanning and reduction of personnel, and it has not always been possible to secure sufficient personnel. In some cases, it must be done. For such an inexperienced operator, it is not easy to perform the monitoring work only with the simple guidance function as described above, resulting in a great effort.

[0005] In addition, while the operator is actually monitoring plant operation for a certain period of time, when the operating state is not necessarily abnormal but becomes a certain operating state, such an operating state is detected. There are cases in which the vehicle is approaching such a driving state, and further, it is desired to provide guidance on appropriate measures in such a case. However, the conventional plant monitoring and control device does not provide any guidance until the abnormal level set by the device manufacturer is reached,
The contents of the guidance and the like are also the contents set by the device manufacturer, and the user cannot change the setting of the abnormal alarm level or the setting of the guidance contents.

The present invention has been made in view of the above circumstances, and enables an inexperienced operator to accurately and easily perform a monitoring operation, and allows a user to make various settings for a guidance function. It is an object of the present invention to provide a possible user open type (customer open type) plant operation alarm guidance device.

FIG. 1 is a block diagram showing a configuration of an alarm guidance device according to a first embodiment of the present invention. As shown in this figure, the alarm guidance device 1 is configured to input and output signals to and from a waterworks plant 3 that is a monitoring target plant via a process controller 2.

To briefly explain the configuration of the water supply plant 3, first, raw water from a river is taken by a water intake pump 301 and sent to a landing well 302, and further a flow meter 303
Through a mixing pond 305 in which a stirrer 304 is installed.
To be sent to The water into which the chemicals for forming the flocs are injected in the mixing pond 305 is stirred by the stirrer 304, and thereafter, the floc forming pond 307
To form flocs 306 gradually. Next, the water of the floc formation pond 307 and the floc 306 are sent to the sedimentation pond 308, where the floc 3
06 forming sediment, and only the supernatant water is filtered
09. The filtration pond 309 has filtration layers 310 to 312 formed of fine sand, slightly coarse sand, and coarse sand, respectively. The water filtered by the filtration basin 309 is sent to a water purification basin 313, where the water is sterilized by chlorine or the like, and then sent to a water distribution basin 316 by a water supply pump 314. Note that reference numeral 31
5 is a water level gauge. The water in the reservoir 316 is distributed to the distribution zone 318 by the distribution pump 317.

The alarm guidance device 1 includes a man-machine interface 4, a guidance rule definition unit 5, a definition rule execution unit 6, a guidance message output unit 7, a guidance image information output unit 8, a trend analysis unit 9, and a guidance registration information storage unit 10. , Analysis information presentation unit 11, guidance SV output unit 12, alarm output unit 13, output command unit 1
4, an in-house broadcast output unit 15, a public line output unit 16, and a portable terminal notification unit 17. Hereinafter, each of these units will be sequentially described.

The man-machine interface 4 is used by an operator to access each of the units 5 to 17, and has a keyboard, a display, and the like.

The guidance rule definition section 5 creates a guidance rule based on an input operation signal from the man-machine interface 4. The operator operates the man-machine interface 4 to
Various settings such as setting of an alarm level and setting of guidance contents can be freely performed. That is, it is also possible to set a certain condition, perform a predetermined calculation, and provide guidance on measures according to the calculation result. For example, assuming the water distribution demand per unit time of the distribution zone 318, the bottom area of the reservoir 316, the water supply capacity of the water distribution pump 317, the initial water level from the water level gauge 315, and the like are known. The water level of the reservoir 316 can be calculated, that is, a water level simulation can be performed. Then, a range of a certain water level width is set for the water level simulation result. If the water level width is within the range, the water distribution amount of the water distribution pump 317 is not changed. It is also possible to provide guidance to the operator about the need to increase or decrease the water distribution amount as driving support information.

The definition rule execution unit 6 executes the guidance rule created by the guidance rule definition unit 5,
Various commands are output according to the execution results. That is, the definition rule execution unit 6 performs an arithmetic process on the process data input from the process controller 2 based on the guidance rule given from the guidance rule definition unit 5, and outputs a command signal corresponding to the calculation result to the guidance message. The information is output to the section 7, the guidance image information output section 8, the trend analysis section 9, the output command section 14, and the like.

The guidance message output unit 7 outputs the guidance message based on the input of the message command signal from the definition rule execution unit 6 to the man-machine interface 4.
Is output. The man-machine interface 4 displays the input guidance message on a display. Further, by giving an input operation signal to the guidance message output unit 7, the operator can select an information presenting method or the like that facilitates the monitoring operation or that suits his or her preference. . For example, displaying each message on the screen so that the color changes according to the registration procedure, selecting the TAG of the status process value from a pull-down menu so that the registration procedure is clear,
Alternatively, it is possible to arbitrarily set what kind of support information is to be displayed for the registered message.

The guidance image information output section 8 outputs guidance image information to the man-machine interface 4 based on a command signal from the definition rule execution section 6 to provide image information as driving assistance information to the operator. It is. Further, the operator can set in advance what kind of image information should be provided to the guidance image information output unit 8. As the guidance image information, for example, there is an instruction manual in which a detailed coping method is described, and image information in which the external shape and the like of a location in question are represented by a photograph or the like.
Such image information is stored in an image information database (not shown) in a file format such as bitmap data or JPEG data. The operator is 1
Next, the guidance is received by the character information from the guidance message output unit 7. More detailed information on this guidance can be obtained from the guidance image information output unit 8. Therefore, even an inexperienced operator can easily and accurately perform the monitoring operation of the plant operation.

The trend analysis unit 9 receives data from the guidance rule definition unit 5, the definition rule execution unit 6, and the guidance message output unit 7, and operates the plant while referring to the data in the guidance registration information storage unit 10. It analyzes the tendency about the state. In the guidance registration information storage unit 10, past performance data on what kind of action the operator in charge has taken when a certain operating state is reached is registered. The operator can set in advance what kind of data or item should be subjected to the trend analysis.

The method of trend analysis is not particularly limited, and may be any method such as a statistical method, a data mining method, or an artificial intelligence method. For example, when a statistical method is adopted, the following analysis method can be considered. That is, the correlation coefficient is calculated for all combinations of certain stored process data,
The combinations are arranged in descending order of the correlation coefficient, and the actions taken at that time are listed in descending order of frequency. If the current driving state is changing in a direction approaching the combination with the highest correlation, information is output to that effect, and in such a case, what kind of action was taken in the past Is the guidance registration information storage 1
If it is stored in 0, the result data is also output.

The analysis information presentation unit 11 inputs the analysis result of the trend analysis unit 9 and outputs the analysis result to the man-machine interface 4 as analysis information that can be displayed on a screen. Since the data output from the trend analysis unit 9 is expressed in a machine language (a combination of “0” and “1”), it is difficult for an operator to immediately understand even if this is displayed on a screen as it is. . Therefore, the analysis information presentation unit 1
Reference numeral 1 denotes an analysis result that is visualized by character information or a graph based on data input from the trend analysis unit 9 and presented to an operator.

The guidance SV output unit 12 supplies a target value as a control signal to the waterworks plant 3 via the process controller 2 based on a command from the trend analysis unit 9. That is, when the trend analysis unit 9 shows a specific analysis result, an appropriate measure is automatically taken without an operator's operation. For example, when a certain trend analysis is obtained for the water level of the reservoir 316 and the water distribution amount to the water distribution area 318, it is possible to know how to control the water supply amount of the water supply pump 314 from now on. The output unit 12 automatically outputs a control signal for the water pump 314 via the process controller 2 without waiting for the operation of the operator. Note that the operator can freely set to cancel the automatic control function by the guidance SV output unit 12 as a matter of course.

The alarm output section 13 emits a predetermined voice or an alarm sound to call the operator's attention when the operation state is set in advance by the operator. That is, the execution result of the definition rule execution unit 6 is output to the output command unit 14, and the operator determines the level at which the output of the definition rule execution unit 6 outputs the command signal. Output command unit 14
Can be set in advance.

The operator also operates the definition rule execution unit 6
Can be set when the output level reaches a more serious level than that for the alarm output unit 13. When such an operation state is established, the output command unit 14 outputs the in-building broadcast output unit 15 and the public line output unit 1.
6 and a command signal to the portable terminal notifying unit 17.

The in-building broadcast output unit 15 automatically broadcasts the contents of the alarm output from the alarm output unit 13 in the hall based on a command signal from the output command unit 14 when the above-mentioned serious operation state occurs. This allows the operator to leave the plant monitoring cab and be in another location,
It will be possible to return to the plant monitoring cab immediately and take appropriate measures. In addition, experienced operators in the hall can hear the broadcast in the hall and rush to the plant monitoring and operation room.

The public line output unit 16 dial-connects to a telephone number preset by the operator based on the command signal from the output command unit 14 in the case of the above-mentioned serious operation, and outputs an alarm output unit. Thirteen alarm contents are automatically output as voice. In this case, the connection destination may be, for example, a management department in the head office of the waterworks bureau. This makes it possible to prevent the user from forgetting to report to the upper-level organization when an abnormality occurs, using a public telephone network such as a general telephone line, and to perform necessary measures systematically.

The portable terminal notifying unit 17 calls a portable terminal set in advance by the operator based on a command signal from the output command unit 14 when the above-mentioned serious driving state is entered, and The contents of the alarm are automatically output by voice or displayed on a screen. Examples of the portable terminal include a mobile phone, a PHS, a pager (registered trademark), and the like, but any other terminal having the same function may be used. In this way, when a certain abnormal driving state or the like occurs, a specific person who can most appropriately cope with this state can be called, and it is possible to have the user be taught about appropriate measures.

In the embodiment shown in FIG. 1, the in-house broadcast output unit 15, the public line output unit 16, the portable terminal notification unit 1
Although the description has been given of the configuration in which the alarm content of the alarm output unit 13 is output as a voice or displayed on the screen as it is, another message set in advance may be output as a voice or displayed on the screen (especially in the case of in-house broadcasting. To avoid unnecessary confusion with third parties, it may be preferable not to broadcast the alarm content as it is, but to broadcast another content that is understood only by the parties concerned.) Also, an output command unit 1
4 outputs a command signal to the alarm output unit 13 first when a certain operation state is set, and outputs a command signal to each unit 15 to 17 when a more serious operation state is set. However, the operator, of course, outputs a command signal to each of the units 15 to 17 at the same time as the alarm output unit 13, or sets the level of the operating state to output the command signal to each of the units 15 to 17 by further subdividing it. It is possible to

Next, a procedure for the operator to create a guidance rule will be specifically described. FIG. 3 is an explanatory diagram showing an example of a display screen displayed on a display when an operator operates the man-machine interface 4 to set a guidance rule in the guidance rule definition unit 5.

The operator first clicks an "edit" button at the upper left of the display screen to pull out a pull-down menu, and clicks a "add element" field from the pull-down menu.
Clicking on the "Add Element" column will bring up a column in which the names of various elements are further described. The operator selects and clicks "AND / OR Element" from among them. Then, as shown in the list screen 31, a guidance rule setting screen 32 appears in which an AND element without a NOT symbol is drawn at the output terminal (a numeral 1 surrounded by a circle in the AND element indicates the AND element). This means that the element is set as “rule element 1”.) In the illustrated state, the “AND” button and the “NOT NOT” button are in a clicked state. Therefore, the screen 32 shows an AND element without a NOT symbol attached to the output terminal. By clicking the "Yes" button, a NOT symbol can be attached to the output terminal. By clicking the "OR" button, an OR element can be displayed on the screen instead of the AND element.

Next, the operator inputs two TAG numbers "D0410001" and "00410002" to the two input terminals of the AND element by using a keyboard, and inputs "rule element 4" as another element connected to the output terminal. select. Of the above TAG numbers, "D04
"100" specifies a certain water supply pump, and "01" and "02" thereafter indicate control / operating states where the water supply pump is placed. For example, this water pump can be controlled by either the central operation panel or the on-site operation panel in the plant monitoring cab, and "01" is a state in which it is placed under the control of the central operation panel. Is shown. The operation state of the water pump is either “operating” or “stopping”, but “02” indicates that the pump is currently operating.

Then, the operator selects "3" minutes as the set time, and further selects "ON" from "ON" or "OFF". That is, the content set on the guidance rule setting screen 32 is “D04100
When two process data represented by TAG numbers “01” and “00410002” are continuously input to the AND element 1 for three minutes, a signal is output to the rule element 4.
It is a rule. The operator presses the “set” button to determine the content if it is determined that such content is acceptable, and clicks the “cancel” button to cancel. In addition, the AND element 1 is displayed in the list screen 31.
If you want to delete only, click the "Delete" button.

The operator repeats the above operation to set the rule elements 1 to 4. And
Click the "List" button at the bottom right of the display screen to display
Only the list screen 31 as shown in FIG. The content of the guidance rule displayed on the list screen 31 is that the AND element 4 outputs an abnormal signal when all the output signals from the AND elements 1 and 2 and the OR element 3 are turned ON. Note that the guidance rule shown in FIG. 4 is defined only by a logical product and a logical sum, but the content of the guidance rule is not particularly limited, and all the arithmetic operations including the four arithmetic operations are performed. It is possible to use

Next, the operator clicks the "Title" button on the display screen, pulls out a pull-down menu in which fields such as "Title" and "Guidance" are described, and displays the title name and the contents as shown in the figure. A guidance message is created and displayed on the list screen 31. Then, if the contents are satisfactory, the user clicks a “register” button to register the contents of the display screen as a guidance rule. When the user wants to delete the contents of the display screen and start the guidance rule creation work again from the beginning, the user clicks the “Delete” button. "Move"
The button is a button used to move a certain rule element to another place on the screen. For example, A
When a new ND element 2 is to be drawn on the list screen 31, the AND element 1 already displayed on the screen is copied and moved below it, and then the TAG number of the input terminal and the like are copied. Can be rewritten as a description for the AND element 2, which is more efficient than creating a rule for the AND element 2 from the very beginning.

Next, the operation of FIG. 1 will be described. After the operator performs various setting operations as described above, the operation of the water supply plant 3 is started. The process controller 2 extracts process data from the water supply plant 3 and outputs the process data to the definition rule execution unit 6. Upon input of the process data, the definition rule execution unit 6 performs an arithmetic process on the process data in accordance with the rule defined by the guidance rule definition unit 5, and outputs the calculation result to the guidance message output unit 7, the guidance image information output unit 8, the trend analysis unit 9 and the output command unit 14.

If the calculation result of the definition rule execution unit 6 indicates that the operation state has reached the operation state set by the operator, though not in an abnormal state, the guidance message output unit 7 A message to that effect is displayed on the display of the man-machine interface 4. The trend analysis unit 9 analyzes the tendency of the driving state so far with reference to the registration data in the guidance registration information storage unit 10, and the analysis information presenting unit 11 visualizes the analysis result using characters, graphs, and the like, and displays the result on a display. I do. In this case, if the trend analysis unit 9 knows what kind of control should be performed in order to return the state where the current tendency is slightly deviating to the normal state, the guidance SV
A command signal for causing the output unit 12 to perform such control is output. Thereby, the guidance SV output unit 1
2 outputs a control signal to the water pump 314 to increase or decrease the amount of water supply by a fixed amount, for example. Therefore, the tendency of departure from the normal state is automatically corrected without any operation by the operator.

When the calculation result of the definition rule execution unit 6 reaches the level of the abnormal state, the output command unit 14 outputs a command signal to the alarm output unit 13. Thus, the alarm output unit 13 emits a voice or an alarm sound to call attention of the operator. At this time, the guidance image information output unit 8 receives the calculation result of the definition rule execution unit 6 and displays a place where the abnormality has occurred on a map, or describes detailed information for restoring the abnormality. The operator's instructions and the like are provided to the operator as image information.

After the alarm output unit 13 outputs an alarm as described above, if the calculation result of the definition rule execution unit 6 falls into a more serious state, the output command unit 14 outputs the in-building broadcast output unit 15 and the public line output. Unit 16 and portable terminal notification unit 1
7 to output a command signal. As a result, the contents of the alarm are broadcasted in the hall, the contents of the alarm are also transmitted to the management department of the head office of the Waterworks Bureau, and a specific operator (for example, a veteran operator) having a portable terminal is called. become.

As described above, according to the alarm guidance apparatus 1 having the configuration shown in FIG. 1, not only when the operating state has fallen into an abnormal state, but also before reaching the abnormal state level, In the event of a more serious situation than the situation, provide optimal guidance according to the situation, and in specific cases, automatically take appropriate measures immediately without waiting for the operator's instruction. Has become. Therefore, even an inexperienced operator can perform the monitoring operation of the plant operation accurately and easily.

The above-mentioned alarm guidance device 1
According to this, various setting contents including the guidance rules can be freely and easily changed by the operation of the operator. Therefore, the operator on the user side can set various items that were conventionally allowed only on the device manufacturer side, and a so-called user open type alarm guidance device can be realized.

FIG. 2 is a block diagram showing a configuration of an alarm guidance device according to a second embodiment of the present invention.
In this embodiment, the components indicated by reference numerals 5 to 17 constituting the alarm guidance device 1 of FIG.
It is provided within. The server 18 is connected to the process controller 2 and the man-machine interface 4 by communication lines 19 and 20 such as ISDN, respectively. Therefore, in the second embodiment, the server 1 belonging to the device manufacturer (or the information distributor)
8 and the man-machine interface 4 belonging to the user constitute an alarm guidance device. The elements 5 to 17 in the server 18 are shown in FIG.
, Are the same as the respective elements 5 to 17, and therefore, duplicated description thereof will be omitted.

According to the above-described second embodiment, the user uses the process controller 2 and the man-machine interface 4 to communicate with the server 18 via the communication lines 19 and 20.
It is only necessary to exchange data with the device, and it is not necessary to purchase special hardware as an alarm guidance device. Therefore, the economic burden on the user can be greatly reduced. In addition, since the main components of the alarm guidance device can be arranged in the server 18 belonging to the device maker, the device maker also has an advantage that maintenance and the like can be easily performed.

Although the alarm guidance devices according to the first and second embodiments have been described as actually taking in process data from a plant to be monitored such as the water supply plant 3, the alarm guidance device is used to check the process state of the plant to be monitored. It is also possible to take in simulation data from a simulation device for performing simulation. That is, in FIGS. 1 and 2, the above-described simulation device is installed instead of the process controller 2 and the water supply plant 3, and the guidance device of the present invention exchanges signals with the simulation device. Can also. With the configuration using such a simulation device, education for an inexperienced operator can be effectively implemented.

[0060]

As described above, according to the present invention, even an inexperienced operator can perform a monitoring operation accurately and easily, and various settings can be made for the guidance function on the user side. It is possible to realize a simple user open type (customer open type) plant operation alarm guidance device.
