TECHNICAL FIELD OF THE INVENTION
The present invention relates to a plant monitoring control system and a monitoring control method for monitoring and controlling various plants such as a chemical plant and a power plant.
[0002]
[Prior art]
BACKGROUND ART Conventionally, a plant monitoring control system for monitoring and controlling various plants such as a chemical plant and a power plant has been widely used.
[0003]
FIG. 56 is a configuration diagram of a conventional plant monitoring and control system.
[0004]
The plant 1 shown in FIG. 1 corresponds to a blast furnace and a rolling plant in the case of a steel plant, each divided power generation unit in the case of a power plant, and each line of a general manufacturing plant. This plant 1 is controlled by a plant control device 2.
[0005]
The establishment 10 is an establishment in which one or more plants 1 such as a factory and a power plant are installed. Inside and outside the business office 10, plant monitoring and operating devices 3a and 3b for operators to monitor and operate the plant 1 via the plant control device 2 are provided. In recent years, input / output devices of the plant monitoring and operating devices 3a and 3b generally use a CRT, a keyboard, and the like.
[0006]
Among them, the plant monitoring and operating device 3a is a form in the case where the monitoring and operating device is installed in a business establishment, and the plant monitoring and operating device 3b performs a monitoring operation at a place remote from the business establishment 10 via the data transmission device 4. It is a form to perform. For example, in a general manufacturing factory, a plant monitoring and operating device is often installed only in a business establishment. On the other hand, for example, in the case of a hydroelectric power plant, the plant is often installed in a remote place. Therefore, the plant monitoring and operating device 3b is installed in a control station away from the power plant (business establishment 10), and the plant of a plurality of power plants is installed. There are many forms of monitoring operation.
[0007]
Also, plant monitoring and operation devices with different functions are installed in the business office and in the head office remote from the business office, and commands are issued to the plant 1 while monitoring the operation status of each business office in the head office. is there. Examples of such are a central power station and a thermal power plant. That is, a plant monitoring and operating device is installed in each of the central power station and the power station, a generated power command is issued from the central power station to the power station, and the power plant is operated at the power station.
[0008]
In recent years, there has been an increasing demand for a reduction in plant operation costs. In a plant monitoring and control system having such a configuration, it is necessary only for a place where the plant monitoring and operating devices 3a and 3b shown in FIG. It is becoming common to have a large number of operators. In addition, as the data transmission means between the plant control device 2 and the plant monitoring and operating devices 3a and 3b is advanced, the distance between them can be increased to several tens of kilometers. For this reason, a remote monitoring operation for monitoring and operating a plurality of plants from a single plant monitoring and operating device installation site has also been generalized. That is, in spite of the fact that the monitoring operation range of the operator at the plant monitoring operation place has been increased, the number of the operators has been tending to be reduced from the viewpoint of reducing the operating cost.
[0009]
For example, as described above, in a monitoring control system for a hydroelectric power plant, it is common to operate a plurality of unmanned power plants at a distance from one manned control station.
[0010]
On the other hand, automation of plant operation has been advanced due to the sophistication of the control device 2, and general operators are less likely to individually monitor and operate the equipment constituting the plant. For this reason, there is a fear that the knowledge of the equipment constituting the plant and the operating technique related to the manual operation without using the automatic control may be reduced for each operator.
[0011]
[Problems to be solved by the invention]
As described above, in the conventional plant monitoring and control system, when an accident or abnormality occurs in the plant, the response is delayed due to the shortage of human resources and the skills of the plant operators assigned during normal operation, or necessary response actions are performed. May not be possible.
[0012]
As a result, problems such as the development of more serious plant abnormalities, the suspension of plant operation for a long period of time, causing significant economic damage, and the loss of some of the functions of the company infrastructure such as power and communication at some plants. There is no possibility that it will occur.
[0013]
In particular, immediately after an abnormality has occurred in the plant, the operator must give the highest priority to emergency emergency operations such as emergency stop of the part where the abnormality occurred and operation to prevent the abnormality from spreading to other plant parts. There is. For this reason, operations for plant recovery operations, abnormalities, and accidents that need to be performed subsequently are often postponed for investigating the cause of the accident and repairing the equipment that caused the abnormality. In particular, these operations may not be able to be performed by the personnel assigned during normal operation, and the current plant condition may be required to recruit necessary technicians and operators at an early stage or to seek the assistance of other technicians. It is important to contact.
[0014]
However, in the conventional plant monitoring and control system, it is necessary for the operator to determine who the technician and the operator to contact, and to make contact using a communication means such as telephone or fax. In particular, it is necessary to accurately grasp the details of abnormalities and accidents that occurred and prepare for communicating to other members, for example, to summarize the time of occurrence and the details of the occurrence of abnormalities, make a phonetic memo and create a fax manuscript This is a very time-consuming task. Further, there is a case where a person to contact by telephone or fax is absent, or a call or a fax is being used, so that it is necessary to contact the user many times for communication. Such an operation is indispensable, but may also result in a delay in the recovery operation and necessary operation of the plant. In addition, since the restoration operation of the plant and these communication operations are complicated, it often happens that the necessary contact information is forgotten or that the telephone memo or the fax manuscript is erroneously written.
[0015]
In emergency operation for plant abnormalities and accidents, it is necessary to understand the state of the plant in detail, but for economic reasons, the information sent from the plant control unit to the plant monitoring and operating unit is always required for normal plant operation. Often limited to. Therefore, a configuration is generally used in which detailed data required for a plant abnormality analysis is stored only at the installation location (site) of the plant control device. For this reason, depending on the nature of the plant abnormality or the accident, it is often necessary to go to the installation location of the plant control device and collect such detailed data, and the recovery of the plant may be greatly delayed.
[0016]
As described above, generally, there is a conflicting relationship between reduction in operating costs, prevention of the spread of damage in the event of a plant accident or the like, and rapid recovery.
[0017]
The present invention has been made in view of such circumstances, and at the time of normal operation, a small number of operators can perform corresponding operations at the installation location of the plant operation operation device, and abnormalities and accidents occurred in the plant. To provide an inexpensive plant monitoring and control system and a monitoring and control method which can easily take an emergency response with a small number of people even in such a case and can restore the plant without errors in a minimum time.

These configurations are the same as those of a personal computer, for example.
[0052]
As described above, the plant data transmission device 7 realizes each function block shown in FIG. 1, that is, each function realization unit, by combining the hardware configuration shown in FIG. That is, a plant data collection unit, a plant state change detection unit, a transmission data editing unit, and a data transmission unit are realized.
[0053]
Hereinafter, the operation of the plant data transmission device 7 will be described for each of these units.
[0054]
<Plant data collection means>
The plant data collection unit 72 includes a plant data collection process for inputting a process amount and the like from the Ethernet interface 704 and a process database stored on the memory 702.
[0055]
FIG. 3 is a diagram illustrating an example of the data structure of the process database.
[0056]
As shown in the figure, the process database 721 includes a serial number 7211 assigned to a process amount to be collected, a process name 7212 assigned to an individual process amount to be input, an input process amount 7213, and a unit 7214 of the process amount. , A process amount type 7215, a control device number 7216 indicating the transmission source of the process amount, and an index number 7217 assigned to each process amount by each control device.
[0057]
FIG. 4 is a flowchart showing the procedure for collecting plant data.
[0058]
FIG. 5 is a diagram showing a data structure of a process amount and the like sent from each control device.
[0059]
There are various methods for implementing this type of data transmission. In the present embodiment, a method is used in which data is sent from the plant control device 2 when the value of the process amount changes.
[0060]
First, when there is a change in the value of the process amount input or calculated by the plant control device 2, the process amount data 201 shown in FIG. 5 is sent to the plant data transmission device 7. Here, the process amount data 201 includes a control device number 2011, an index 2012, and a value 2013, and is output to the plant data transmission device 7 via the data transmission device 4 (ST1).
[0061]
The process data 201 is received by the plant data collection unit 72 (ST1), and the control unit number 2011 and the index 2012 are referred to and compared with the transmission control unit number 7216 and the index 7217 on the process database 721 (ST2, ST3). ). The process database 721 is searched until these match (ST4) (ST5), and the value 2013 on the process amount data 201 is set in the area of the process amount 7213 of the matching item (ST6).
[0062]
By the above processing, the process amount 7213 on the process database 721 is always kept up to date.
[0063]
<Plant state change detection means>
The plant state change detection unit 73 includes a plant state change definition table 731 and a state change detection process.
[0064]
FIG. 6 is a diagram showing an example of the data structure of the plant state change definition table.
[0065]
FIG. 7 is a flowchart showing a state change detection procedure.
[0066]
The plant state change definition table 731 includes a serial number 7311, a process amount number 7312 that defines the serial number 7211 on the process database 721 in which a process amount required to detect a plant change, and a plant state change. It has a default value 7313 for defining a calculation method for detection, an operator 7314, a plant state change 7315 implied by the result of this calculation, and an event number 7316.
[0067]
In the state change detection process, the plant state is determined according to the calculation method shown in the plant state change definition table 731. That is, the contents of the process amount number 7312 are sequentially referred to, and the processing shown in FIG. 7 is repeated until the value becomes a value indicating “end”, for example, “999”.
[0068]
First, result = 0 is set (ST11), and then a process amount number is extracted (ST12). If the content of the process amount number 7312 is not "999" (ST13), the process amount of the serial number matching the above number is extracted from the column of the process amount 7213 of the process database 721 (ST14). This is compared with the value of the specified value 7313 (ST15, ST16). If they are the same, they are set to "1" (ST17), and if they are different, they are set to "0" (ST18) and the process returns to step ST12.
[0069]
After performing this comparison for each row of the plant state change definition table 731 (ST13-> ST19), if the result of the logical operation of the result by the operator shown in the operator 7314 becomes "1", the row is displayed. Is determined to have changed the plant state (ST19).
[0070]
When there is a plant state change, an event is generated by passing the plant state change name in the plant state change 7315 of the plant state change definition table 731 and the event number in the event number 7316 to the plant data editing unit 74. Is notified (ST20). That is, when a predetermined plant state change occurs, the plant state change detection unit 73 passes the event number to the plant data editing unit 74 in the present embodiment, and to, for example, a fax manuscript creation unit and a document data selection unit in each embodiment described later. Thus, a change in the plant state is notified.
[0071]
For example, in FIG. 6, when the unit 1 is operating (the process amount number 359 is “1”) or the unit 1 is being started (the process number 361 is “1”), the A tank inlet temperature is high (the process amount number 3 is “1”). 4) shows an example in which it is determined that a change in the plant state, that is, the A tank temperature is high.
[0072]
<Transmission data editing means>
The transmission data editing unit 74 receives the change in the process amount from the plant state change detection unit 73 and the latest state of the process data from the process database 721, and creates documents indicating various plant states. Here, a document (hereinafter referred to as an event record) in which changes in binary data among the process amounts are arranged in a time series is shown as an example, but other various documents can be created.
[0073]
FIG. 8 is a diagram showing an example of an event record format.
[0074]
In order to obtain data necessary for the event record 741, first, process amount data 201 similar to that shown in FIG. 5 is received from the plant data collection unit 72, and the control device number 2011, index 2012, and process amount 2013 are referred to. Next, the plant state change detection unit 73 compares the value of the control device number 2011 and the value of the index 2012 with the transmission control device 7216 and the index 7217 on the process database 721. Thus, it is possible to determine which process amount is the transmitted process amount data 201 and read out the process amount name 7212 to prepare necessary data. In addition, the occurrence time is read from a clock 708 constituting the plant data transmission device 7.
[0075]
<Data transmission means> <Destination list>
FIG. 9 is a flowchart showing the processing of the data transmission unit.
[0076]
FIG. 10 is a diagram showing an example of the data structure of the transmission destination list 76.
[0077]
According to the data transmission unit 75, when the transmission data editing unit 74 notifies the transmission data editing completion (ST21), the data transmission unit 75 reads out the transmission destination list 76 of FIG. 10 including the serial number 761, telephone number 762, and transmission destination name 763. The telephone number 762 is extracted (ST22).
[0078]
Until a number indicating the end, for example, "9999-9999-9999" is extracted (ST23), the following processing is repeated.
[0079]
First, a telephone connection command is sent to the modem with a telephone number added (ST24). When the connection is successful (ST25), the transmission data of the transmission data editing unit 74 is extracted, and the data is sent to the modem 706 (ST26).
[0080]
If the transmission is successful (ST27), the process returns to step ST22. Here, if the transmission has failed (ST27) or if the connection with the other party has failed (ST25), the process returns to step ST24 and is retried. If the retry has been completed, the process returns to step ST22.
[0081]
Thus, data is transmitted to all transmission destinations.
[0082]
Next, a plant data display device as a data transmission destination will be described.
[0083]
<Plant data display device>
FIG. 11 is a block diagram in the case where the plant data display device is constituted by a computer to which a microprocessor is applied.
[0084]
In the plant data display device 6 shown in the figure, a microprocessor 601, a memory 602, a hard disk 603, an RS232C interface 605, and a CRT controller 607 are connected to a CPU bus. The RS232C interface 605 is connected to the public line 9 via a modem 606. Further, a CRT monitor 608 and a keyboard 609 are connected to the CRT controller 607.
[0085]
Here, the modem 606 in FIG. 11 corresponds to the public line transmission means 61 in FIG. 1 and is used for input from the plant data transmitting device 7 via the public line. The keyboard 609 is used by the operator of the plant data display device 6 to give an instruction such as a display request to the device, and corresponds to the data input unit 64 in FIG.
[0086]
The microprocessor 601, the memory 602, and the hard disk 603 in FIG. 11 are for realizing the display data editing means 62 and the data input processing means 65 by software, and are configured in the same manner as, for example, a personal computer. .
[0087]
The plant data display device 6 receives a request from an operator and displays various data. In this way, functions similar to those of a general plant monitoring device are realized.
[0088]
The detailed configuration and operation of each unit have been described above. The overall operation will be described below.
[0089]
<Overall operation of plant data transmission device and plant data display device>
First, the data transmission device connection unit 71 receives process data from the plant control device 2 via the data transmission device 4, and passes the data to the plant data collection unit 72.
[0090]
The plant data collection unit 72 always retains the latest state data of the necessary process data using the obtained data. The plant state change detection unit 73 performs an arithmetic process on the process amount held by the plant data collection unit 72, and detects a change in the state of the plant such as a plant abnormality.
[0091]
The plant data collection unit 72 passes the stored process amount data to the plant data editing unit 74 when the plant state change occurs.
[0092]
The plant data editing unit 74 edits this data into a data configuration suitable for a public line, and delivers it to the data transmission unit 75. The data transmission unit 75 refers to the transmission destination list 76 and issues a transmission request including a transmission destination number and data to be transmitted to the public line transmission unit 77.
[0093]
The public line transmission unit 77 connects the line of the designated transmission destination, and after the line is connected, transmits the passed data to the plant data display device 6 via the public line 9.
[0094]
In the plant data display device 6, the transmitted data is converted into digital data by the public line transmission unit 61, and the data is passed to the display data editing unit 62. The display data editing unit 62 receives a display request from the data input unit 64 by the operator, converts this data into a format suitable for display, and passes the data to the data display unit 63. The data display unit 63 displays the plant data so that the operator can check the state of the plant.
[0095]
As described above, the operator of the plant data display device 6 causes the data display unit 63 to display the detailed data of the plant 1 when the plant state changes.
[0096]
As described above, according to the plant monitoring and control system according to the embodiment of the present invention, the following effects can be obtained.
[0097]
First, when the plant enters the plant state set in the plant state change detection unit 73, the change in the plant state up to the plant state change is automatically transmitted to the plant data display device 6 specified in advance via the public line 9. The status change of the plant can be confirmed by the plant data display device.
[0098]
Since the plant data display device 6 is connected to the plant data transmission device 7 via the public line 9, the plant data display device 6 can be installed at a location remote from the plant data transmission device 7, and is applied to a hydroelectric power plant that monitors and controls the plant from a distance. In the event that an abnormality occurs in the plant by installing the plant data display device 6 in the control center, the operator is required to provide more detailed data in addition to the data transmitted for normal operation. It can be obtained without.
[0099]
Further, when the plant data display device 6 is installed in the head office away from the plant, the operation data of the plant can be obtained from a plurality of plant installation locations at the time of an event such as the start-up of the plant, and the operator of the plant can be obtained. The operation status of the plant can be grasped in a timely manner without any trouble.
[0100]
In addition, since the public line 9 is used for data transmission, the installation cost of equipment required for data transmission can be reduced, and the public line 9 is not normally used, and the plant set in the plant 1 is not used. Since it is used only when a state change occurs, the line use cost can be minimized.
[0101]
Although the present embodiment has been described with a configuration in which data is obtained from the public line 9 as the plant data display device 6 and a dedicated device for displaying received data on a screen of a CRT or the like is added, the present invention has such a configuration. It is not limited to the case where a dedicated device is provided. For example, the function of the plant data display device 6 may be added to the conventional plant monitoring and operation device 3 and the like, and the same function as the plant data display device 6 may be realized at the installation location of the plant monitoring and operation device 3, for example.
[0102]

[0199]
Next, the operation of the plant monitoring and control system configured as described above will be described. The description of the same parts as in the first embodiment is omitted.
[0200]
FIG. 30 is a flowchart showing the processing of the data transmission unit of the present embodiment.
[0201]
This flowchart is obtained by adding an alternative transmission destination processing step ST89 to the flowchart shown in FIG. 9 in the first embodiment, and in steps ST81 to ST88, processing similar to steps ST21 to ST28 in FIG. 9 is performed. . In step ST89, when the telephone connection or the data transmission fails in the telephone connection to the modem or in the data transmission after the telephone connection, the alternative destination processing is started.
[0202]
FIG. 31 is a flowchart showing the procedure of the alternative transmission process.
[0203]
FIG. 32 shows the data structure of the alternative transmission destination list.
[0204]
The alternative transmission destination list 87 illustrated in FIG. 32 is an example in which two alternative destinations are provided, and a first alternative destination telephone number 872 and a first alternative destination destination name 873 and a second A second alternative destination telephone number 874 and a second alternative destination destination name 875 are provided.
[0205]
In the alternative destination processing of FIG. 31, first, the telephone number of the destination to which data is transmitted in place of the destination indicated in the destination list 76 is extracted from the first alternative destination telephone number column 872 of the alternative destination list 87. If a telephone number has been set (ST92), a telephone connection request is made to the modem 77 (ST93). After the connection (ST94), the transmission data is extracted from the plant data editing unit 74 and sent to the modem (ST95).
[0206]
If the above processing ends normally (ST96) or there is no alternative destination (ST92), the process returns to step ST89 in FIG. 30, but if it fails, after retry (ST97), the second alternative destination in the alternative destination list 87 is changed. The telephone number of the next alternative transmission destination is extracted from the telephone number column 874, and the same processing as that for the first alternative transmission destination (ST91 to ST96) is performed (ST101 to ST106).
[0207]
By the above processing, even if the initial connection destination is busy and the connection is not possible, the plant state is notified to the alternative contact without bothering the operator.
[0208]
As described above, according to the plant monitoring and control system according to the embodiment of the present invention, the same effects as those of the first embodiment can be obtained. The transmission unit 75b attempts to transmit data by referring to the transmission destination list 76. If the transmission fails, the alternative transmission destination list 87 is referred to and data is transmitted instead of the transmission destination in the transmission destination list. The telephone number is taken out and the data from the plant data editing unit 74 is transmitted.
[0209]
Therefore, even when the other party to which the plant data is to be transmitted is on the phone or the plant data display device is not operating, the data can be automatically transmitted to a predetermined alternative destination.
[0210]
As a result, multiple plant data display devices are installed at important contacts, and even if one of the devices is broken down or occupied for other work, human intervention is not required. Necessary data can be transmitted.
