It relates to a framework for developing monitoring data processing software used in the development of monitoring data processing software in a monitoring and control system that monitors flow rate, room temperature, and electric energy.In particular, each monitoring data corresponds to a monitoring system in each field. The present invention relates to a monitoring data processing software development framework that can save labor when developing processing software.

[0002]

2. Description of the Related Art Conventionally, in order to save labor, in various management operations such as water distribution management and building management, collection, processing, display, etc. of various data necessary for management (hereinafter referred to as monitoring data) are automatically performed. Monitoring and control system is used. Examples of the monitoring data include the water level of a reservoir and the flow rate of a distribution pipe in water distribution management, and the room temperature and power consumption of each floor and each room in building management.

FIG. 8 is a block diagram showing a configuration of a conventional supervisory control system. As shown in this figure, usually, the monitoring control system includes one central management unit 6 and a plurality of monitoring control objects 9 centrally managed by the central management unit 6.
It is composed of FIG. 1 illustrates one monitoring control target 9 among the plurality of monitoring control targets 9.
The monitoring control target 9 includes, for example, the above-described distribution reservoir and water distribution pipe in water distribution management. Also,
In the vicinity of the monitoring control object 9, a measuring device 10 for measuring monitoring data (for example, a water level of a reservoir, a flow rate of a distribution pipe, etc.)
And a control device 11 for controlling the monitoring and control target 9 based on the control data from the central management unit 6 are provided respectively.

The central management unit 6 is connected to the measuring device 10 and the control device 11 via a network 8, and the control device 11 receives control data from the central management unit 6 via the network 8. While measuring device 10
Transmits the measurement result as monitoring data to the centralized management unit 6 via the network 8. That is, the monitoring and control system shown in FIG. 1 is configured to enable remote monitoring of the monitoring and control target 9 via the network 8.

On the other hand, the central management unit 6 includes a monitoring data processing unit 3 for performing various arithmetic processing and the like on the monitoring data transmitted from the measuring device 10, and a data storage for storing the data processed by the monitoring data processing unit 3. Unit 1 and a CRT (cathoderay) for displaying monitoring data necessary for operator operation.
tube) 2, a display processing unit 4 that outputs monitoring data for display to the CRT 2, receives data input by an operator from a keyboard (not shown), and generates control data to be transmitted to the control device 11. A control data processing unit 5, a monitoring data processing unit 3, a display processing unit 4, and an event management unit 7 that manages events storing data flowing between the control data processing unit 5 and the network 8. .

In the above configuration, when control data is transmitted from the control data processing unit 5, the control data is transmitted to the control device 1 via the event management unit 7 and the network 8.
1 is received. Thereby, the measurement by the measuring device 10 is performed under the control of the control device 11. Specifically, the measuring device 10 measures the water level, the flow rate, and the like of the monitoring control target 9 and transmits the measurement result to the event management unit 7 via the network 8 as monitoring data.

When the monitoring data is received by the event management unit 7, the monitoring data is sent to the monitoring data processing unit 3 as an event by the event management unit 7, and thereafter, the monitoring data processing unit 3 stores the monitoring data in the data storage unit 1. Is stored in Similarly, monitoring data is sequentially transmitted from another measuring device 10 (not shown) to the event management unit 7 via the network 8, and the monitoring data is also transmitted to the data storage unit 1.
Is stored in Thus, the data storage unit 1 stores
Each monitoring data in the plurality of monitoring control targets 9 is stored as a database.

[0008] A selection screen for selecting desired monitoring data from a plurality of monitoring data is displayed on the CRT 2 under the control of the display processing unit 4, and the operator displays the desired monitoring data from the selection screen. When selected, the display processing unit 4 sends a request command for reading the monitoring data from the data storage unit 1 to the event management unit 7 as an event. Thereby, the event management unit 7 sends the event to the monitoring data processing unit 3. When receiving the event, the monitoring data processing unit 3
After reading the monitoring data from, this is sent to the event management unit 7 as an event.

The event management section 7 sends the received event (monitoring data) to the display processing section 4. As a result, after the display processing unit 4 converts the monitoring data included in the event into data suitable for display, desired monitoring data is displayed on the CRT 2. In this way, the operator checks desired monitoring data from the plurality of monitoring data collected by the central management unit 6 as necessary.

Further, the monitoring data processing unit 3 includes the measuring device 1
Monitoring data transmitted from the data storage unit 1
In addition to the process of storing the data, the following data processing process is also performed. In other words, in this data processing, the monitoring data processing unit 3 reads out the monitoring data stored in the data storage unit 1 at a fixed cycle, and performs necessary arithmetic processing on the monitoring data individually. Thus, after processing data is generated, it is stored in the data storage unit 1 again.

Further, the monitoring data processing unit 3 compiles the monitoring data stored in the data storage unit 1 in a time series at regular intervals, and then stores the monitoring data in the data storage unit 1; In response to a request from the processing unit 4, the corresponding designated time-series monitoring data is read from the data storage unit 1, and is read via the event management unit 7.
Perform processing to send to. In practice, the multiple processes described above are:
One or more types of software (programs)
According to the procedure described in That is, in the monitoring control system, monitoring data processing software for processing the above monitoring data is used.

[0012]

In the monitoring control system described above, monitoring data processing software for processing a plurality of monitoring data collected via the network 8 in the centralized management unit 6 is used. That said. Considering the development of this monitoring data processing software, the monitoring target and the processing specifications vary greatly depending on the field and the requirements of the customer, so that the development requires a complicated method and complicated programming.

More specifically, since the types of monitoring data in the monitoring target differ depending on the field, there are a plurality of processing methods for each monitoring data, and programming for realizing these methods is complicated. For example, in water distribution management, the water level of distribution reservoirs in water distribution stations and the flow rate of water pipes are monitored as monitoring data, and in building management, the room temperature of each floor and each room and the amount of power used are monitored as monitoring data. Monitoring.

The monitoring data is subjected to arithmetic processing according to the type and nature of the data, and processing for storing data of the arithmetic result in the data storage unit 1 is extremely performed. Monitoring data processing software with complex structure must be developed individually.

Further, monitoring data processing software specialized for various fields such as water distribution management and building management described above is required. Further, since the system specifications are different for each customer, monitoring data processing software corresponding to the new system specifications is required.

As described above, developing monitoring data processing software for each field and for each customer, even though the software has similar functions, requires an extremely large work load on the programmer. Furthermore, in recent years, the functions required of software have become increasingly sophisticated, and the monitoring data processing software has become complicated and large. Therefore, it has been necessary to standardize the software.

In the conventional monitoring and control system, monitoring data may be collected and processed every minute or every five minutes, or may be processed every hour, depending on the customer's request. Furthermore, when a certain time is reached every day, the processing for 24 hours up to that time may be performed, or the processing for one month after reaching a certain time on a certain day every month may be performed. Thus, the cycle of data collection and processing (specifications)
In addition, since there is a wide variety according to customer requirements, in the development of monitoring data processing software, complicated programming for realizing processing execution in each cycle is required.

Further, the monitoring data processing software includes:
The data structure ranges from simple to complex because it is used to store only the current value for each monitoring data or to store monitoring data processed in each cycle in chronological order. is there. Therefore, in the development of monitoring data processing software, not only programming according to data storage in various cycles, but also programming for realizing access processing to a data structure according to each cycle is required. Thus, in the development of conventional monitoring data processing software,
In order to deal with such a problem, it has been an important issue to construct reusable software so that it can be used commonly for monitoring and control systems in various fields.

In recent years, object-oriented framework technology has been introduced for the development of software such as business applications. For example,
Japanese Patent Application Laid-Open No. Hei 10-222369 discloses an object-oriented framework for putting together a plurality of standardized classes, which can be repeatedly used as a solution to a specific problem, in a framework and developing business applications. He talks about technology.

However, this publication does not particularly mention the above-mentioned monitoring and control system, but only discloses a general program development technique using a framework. It does not solve any problems peculiar to the supervisory control system that occur when developing processing software. In other words, the framework used in this technique is flexible in terms of the expression of various monitoring target items in the monitoring control system, the execution of monitoring data processing by means of arithmetic processing and periodicity, and the access to various data structures. Can't cope with it.

The present invention has been made in view of the above,
In the development of supervisory data processing software for supervisory control systems, the purpose is to obtain a framework for developing supervisory data processing software using object-oriented techniques that can reduce the work load of programmers and simplify programming. .

[0022]

In order to achieve the above object, a monitoring data processing software development framework according to the present invention is used for developing monitoring data processing software for processing monitoring data in a monitoring control system. A monitoring data processing software development framework to be used, which comprises at least a data acquisition function for acquiring the monitoring data, an arithmetic processing function for arithmetically processing the monitoring data, an item class in which a monitoring target item is converted into an object, A data set class in which the data structure of the system storage unit is converted into an object, a cursor class for searching in the object of the data set class, and a predetermined process executed at an arbitrary fixed period. Time switch class To manage instances generated by the class is obtained so as to include an application class.

According to the present invention, when new monitoring data processing software is developed using the monitoring data processing software development framework, most classes are framed even if the field to be monitored or the arithmetic processing is different. Since these classes are provided in the work, these classes can be inherited by new monitoring data software as they are, so that the number of newly implemented parts during development is extremely small. To be specific, when adding a new process to monitor items and monitoring data, simply define a new monitor item that inherits the original item class and implement a new calculation process. Since the time switch class and the like can be inherited and used as they are, the class can be reused.
Therefore, according to the present invention, even if the number of monitoring target items that require a different type of arithmetic processing newly increases, only this implementation need be programmed.

In the monitoring data processing software development framework according to the next invention, the application class owns the item class, the data set class, and the time switch class. According to the present invention, since the application class has a relationship of owning the item class, the data set class, and the time switch class, the application class manages instances generated by the item class, sends a time trigger to the time switch class, and the like. .

In the monitoring data processing software development framework according to the next invention, the data set class owns the cursor class. According to the present invention, the other class requests an instance of the cursor class from the data set class, and requests the data set class to perform data read / write processing using the instance.

The monitoring data processing software development framework according to the next invention is designed to specialize in monitoring data processing software corresponding to monitoring control systems in different fields. According to the present invention, a monitoring data processing software development framework specialized for each field is provided. For example, there are monitoring data processing software development frameworks specializing in water distribution management and building management, respectively, and using the prepared monitoring data processing software development frameworks, monitoring data processing Software can be developed in the same manner as described above. Therefore, since a framework for developing monitoring data processing software is prepared in advance for each field, the actual programming operation is only the operation of customizing only the differences in requirements for each customer.

A monitoring data processing software development framework according to the next invention derives the application class, the item class, the data set class, the cursor class, and the time switch class for each monitoring control system in a different field. It is intended to be used. According to the present invention, each of the monitoring data processing software development frameworks prepared for each field includes classes derived from an application class, an item class, a data set class, a cursor class, and a time switch class. Therefore, new monitoring data processing software can be developed by a simple method of inheriting the derived class.

A framework for developing monitoring data processing software according to the next invention derives the application class, the item class, the data set class, the cursor class, and the time switch class for each monitoring control system in different fields. Each class is specialized in monitoring data processing software for each field. According to the present invention, in each of the monitoring data processing software development frameworks prepared for each field,
The application class, item class, data set class, cursor class, and time switch class are provided, and each class is specialized in monitoring data processing software for each field. In other words, by using the respective monitoring data processing software development frameworks composed of the specialized classes, the actual programming work is only the work of customizing only the differences in requirements for each customer.

In this figure, a supervisory control system framework 10 is used as the supervisory data processing software development framework.
1 is shown. The monitoring control system framework 101 is used to support the development of monitoring data processing software in the monitoring system described above. This monitoring and control system framework 101 includes:
Application class 102, item class 103, time switch class 104, data set class 10
5, including the cursor class 106. The function in the lower frame of the rectangle of each class shall be expressed.

Specifically, the application class 10
2 has a timer trigger transmission function and an item acquisition function, and the item class 103 has a data acquisition function and an arithmetic processing function. Time switch class 104
Has an ON processing function and an OFF processing function. The data set class 105 has a data reading processing function and a writing processing function.
Has a data position calculation function, a time movement function, and an item movement function. These functions will be described later in detail.

The application class 102 is the only class object in the monitoring data processing software to be developed, and must always have one.
The application class 102 has an item class 103 and a time switch class 104 with respect to other classes.
And the data set class 105.

Further, the data set class 105 has a cursor class 106. The application class 102 manages a plurality of instances generated by the item class 103, and has an item acquisition function for acquiring the item when an item is requested from an external class. Further, the application class 102 is provided with a timer (not shown), and a timer trigger transmission function for sending a trigger to the time switch class 104 owned by itself at specified time intervals (for example, 1 second). It has.

The item class 103 is a class that converts (represents) an item to be monitored into an object. The item class 103 includes a data acquisition function for acquiring monitoring data and an operation for executing an arithmetic process according to its own characteristics and types. It has a processing function. Here, the monitoring control system framework 1
The monitoring data processing program (software program) developed by using the application class 01 can create a plurality of instances provided by the item class 103 as needed, and the plurality of instances are all managed by the application class 102.

The time switch class 104 can set a cycle, and has a function of determining whether or not the cycle has been reached from the current time when the above-described trigger is sent from the application class 102. In the time switch class 104, an ON process when the determination result is "yes" and an OFF process when the determination result is "no" are mounted in advance. Here, in the monitoring data processing software (software program) to be developed, the time switch class 104
Is created, and this instance is managed by the application class 102.

Here, with reference to FIG. 2, it will be described that various processes are executed at various periods (timings) by combining instances of the time switch class 104. In this figure, every minute switch 302
This is an instance of the time switch class 104 that executes ON processing at 0 second every minute, and executes OFF processing at other times. The hourly switch 306 executes an ON process when the hour reaches 0 minutes.
This is an instance of the time switch class 104 that executes FF processing. That is, time switch class 1
Examples of the instance 04 include a switch 302 per minute and a switch 306 per hour.

In step 301, when a trigger is transmitted from the application class 102 (see FIG. 1) to the time switch class 104, in step 303,
It is determined whether or not the time has reached 0 seconds every minute since the trigger was issued. That is, here, it is determined whether or not the timing is a one-minute cycle. Here, the time determination processing in step 303 is provided by the time switch class 104.

If the result of the determination in step 303 is "Yes", that is, if the timing is a one-minute cycle, in step 304, an ON process is executed. Here, the ON processing in step 304 is a part implemented in the time switch class 104, and may be any processing. That is, the type of the ON process is not limited as long as the process is executed at a timing of 0 seconds per minute (every minute). That is, the ON processing is a part that the programmer freely implements according to the monitoring target and the processing specifications.

On the other hand, if the decision result in the step 303 is "No", that is, if the timing is other than the one-minute cycle, in the step 305, the OFF process is executed. Here, the OFF processing is performed by the programmer in the time switch class 1 in the same manner as the ON processing described above.
04, and may be any processing. That is, the OFF process is a process at a timing other than the timing of 0 seconds per minute. In addition, this OF
The F process is not necessarily implemented, and does not need to be implemented if unnecessary.

When a trigger is transmitted from the application class 102 (see FIG. 1) to the time switch class 104 in the hourly switch 306 in the same manner as the above-described minute switch 302, the trigger is transmitted in step 307. From the above, it is determined whether or not 0 seconds have passed. That is, here, it is determined whether or not the timing is a one-hour cycle. Here, the time determination processing in step 307 is provided by the time switch class 104.

If the result of the determination in step 307 is "yes", that is, if it is a one-hour period, the ON process is executed in step 308 in the same manner as in step 304 described above. If the determination result in step 307 is “No”, in other words, if the timing is other than the one-hour period, in step 309, the OF is performed in the same manner as in step 305 described above.
The F process is executed. Here, the ON processing in step 308 and the OFF processing in step 309 are parts that are freely implemented by the programmer.

FIG. 3 shows the data set class 1 shown in FIG.
FIG. 05 is a diagram showing the relationship between the cursor class 106 and the target data structure 141. The data set class 105 is a class for enabling various data structures in the data structure 141 of the data storage unit 1 (see FIG. 8) to be expressed, and encapsulation of hiding each data structure from the outside. In this way, the independence is enhanced, and a read processing function and a write processing function as unified access means are provided. That is, the data set class 105 is obtained by converting the data structure 141 of the data storage unit 1 (see FIG. 8) into an object. The data set class 105 and the cursor class 106 have a relationship in which the data set class 105 owns the cursor class 106.

The cursor class 106 is a class used when an external class accesses the data set class 105. The cursor class 106 specifies a time and an item, and the position of the data is located in the object of the data set class 105. It also has a data position calculation function for calculating whether or not, a time movement function that enables the cursor position to be moved in unit time, and an item movement function that enables the cursor position to be moved in item units. That is, the cursor class 106
Has a function of searching in the object of the data set class 105.

Here, the instance of the external class is
An instance of the cursor class 106 is received from an instance of the data set class 105, and by specifying a time or an item in the instance, the data set class 105 is caused to obtain a read (write) position of the data. When an instance of an external class accesses an instance of the dataset class 105, the instance of the cursor class 106 is requested to the dataset class 105, and the instance is used to send a data structure to the dataset class 105. 1
Request a reading process or a writing process for 41.

FIG. 4 shows the configuration of the development target software 111 developed using the above-described monitoring control system framework 101. Here, as the development target software 111, monitoring data processing software for water distribution management will be described as an example. The software 111 to be developed shown in this figure is a distribution management monitoring data processing application class 112, a distribution management measurement item class 11
3, a time switch class 114 for each hour and hour 0, a data set class 115 for one month, and a cursor class 116 for data set for one month.

The water distribution management monitoring data processing application class 112 and the water distribution management measurement item class 1
13, the hourly hourly time switch class 114, the one-month data set class 115, and the one-month data set cursor class 116 are included in the framework 101 for the monitoring control system, respectively, the application class 102, the item class 103, It is a subclass defined inherited from the time switch class 104, the data set class 105, and the cursor class 106.

In the software 111 to be developed, a monitoring data processing application class 112 for water distribution management
Is a subclass defined by inheriting from the application class 102, and is the only application class for water distribution management monitoring data processing software. Also, there is only one instance of the distribution management monitoring data processing application class 112. The distribution management monitoring data processing application class 112 is implemented so as to manage the instances generated by the necessary distribution management measurement item class 113 in the initialization processing executed when the software is started.

The water distribution management measurement item class 113 is a subclass defined inherited from the item class 103. That is, the water distribution management measurement item class 113 is a subclass that defines that the monitoring target item is of the type “measurement item”, and the monitoring data of the monitoring target is transmitted to an instance of the water distribution management measurement item class 113. Can be In addition, when it is necessary to perform arithmetic processing on the monitoring data received by the water distribution management measurement item class 113, it may be implemented in the water distribution management measurement item class 113.
Furthermore, the water distribution management measurement item class 113 generates instances as many as the actual measurement items when the software is executed, and these instances are managed in the application class 102.

The hourly hourly time switch class 114 is
This is a subclass defined by inheriting from the time switch class 104, and is set to have a cycle of turning on at 0 minute every hour. In the hourly minute switch class 114, an ON process (see step 308 in FIG. 2), that is, a process to be executed at hourly hour is implemented. In addition, the hourly time switch class 114
, A time switch class that is set to a cycle that is turned ON at 0 seconds per minute may be used as a subclass.

The one-month data set class 115 is a subclass defined by inheriting from the data set class 105, and can store data of a monitoring target item (for example, a measurement item) for one month at a cycle of 0 minutes every hour. This is the definition of the data structure interface.
The one-month data set cursor class 116 is a subclass defined by inheriting from the cursor class 106. The one-month data set cursor class 116 is used for the data structure indicated by the one-month data set class 115 to specify the specified date and time and the specified item data. It is implemented in addition to the data location calculator so that it can calculate where is located.

In the software 111 to be developed, similarly to the monitoring control system framework 101, the distribution management monitoring data processing application class 112
It has a minute time switch class 114 and a one month data set class 115, and the one month data set class 115 has a one month data set cursor class 116.

FIG. 5 is a diagram showing a case where the data of the “measurement item”, which is the monitoring target item, is subjected to arithmetic processing at 0 minute each hour in the development target software 111 shown in FIG.
FIG. 11 is a diagram illustrating a flowchart for executing a process of writing to a monthly data set class. In FIG. 5, after the program is started, in step 201, a trigger is sent to the time switch class 104 at regular intervals by the timer function of the application class 102.

Specifically, the application class 10
An instance of the hourly hourly time switch class 114 generated by inheriting from the time switch class 104 an instance of the distribution management monitoring data processing application class 112 inherited from the time switch class 104 by the timer trigger transmission function at a specified fixed interval. Send a trigger to. As a result, it is determined in step 201 whether or not it is 0 minute every hour. If the determination result is “No”, the determination is repeated.

Then, when the hour reaches 0 minutes, step 20
1 is "yes", and in step 202,
An instance of the cursor class 106 is obtained from an instance of the data set class 105. In particular,
A process of inquiring about an instance of the data set class 115 for one month inherited from the data set class 105 and acquiring an instance of the cursor class 116 for data set for one month inherited from the cursor class 106 is performed.

Next, in step 203, the program inquires of the instance of the application class 102 to obtain an instance of the item class 103. Specifically, from the instance of the distribution management monitoring data processing application class 112 inherited from the application class 102, the instance of the water distribution management measurement item class 113 inherited from the item class 103 is extracted in the order of registration.

Next, in step 204, the program causes an instance of the water distribution management measurement item class 113 to execute a calculation process. Specifically, the calculation processing function of the instance of the water distribution management measurement item class 113 acquired in step 203 is executed. Then, step 20
In 5, the program acquires the data of the operation result from the instance of the item class 103. Specifically, in step 204, data (item data) subjected to arithmetic processing is acquired from the instance of the water distribution management measurement item class 113.

Next, in step 206, the item data is written into a data set using the cursor class 106. Specifically, the date and time and the item are designated for the instance of the one-month data set cursor class 116 acquired in step 202, the data write position is calculated, and the data acquired in step 205 is calculated using the cursor. Is written to the data set class instance for one month.

Next, in step 207, it is determined whether or not there is the next instance of the water distribution management measurement item class 113. If the determination result is "yes", the process returns to step 203, and the above-described processing is repeated. It is. That is, in the instance ON processing function of the hourly minute switch class 114 (see FIG. 2: Step 308), the processing from Step 203 to Step 207 is performed as follows.
The process is repeated for the number of instances (items) of the water distribution management measurement item class 113. On the other hand, if the determination result is “No”, the process proceeds to step 208. Step 2
At 08, it is determined whether to end the program,
If the determination is "no", the process returns to step 201 and the above-described processing is repeated. On the other hand, if the determination is "yes", the program ends.

As described above, when the development target software 111 is developed using the monitoring control system framework 101 according to the first embodiment, the processing from step 201 to step 208 shown in FIG. 5 is performed. When programming, since most of the processing is prepared in the supervisory control system framework 101, it is sufficient to inherit each class as it is, so that the programmer can greatly simplify the development as well as greatly reduce the development effort for the programmer. effective.

For example, in the development of the development target software 111, the cycle determination processing as performed in step 201 is provided by the time switch class 104, so that it is not necessary to newly program this cycle determination processing. In this development, step 2
In 04, the calculation processing of the item is executed by the common interface, so that it is not necessary to newly program the calling process due to the difference in the item class. further,
Since the data structure is hidden by the data set class 105, the troublesome read / write processing for the data structure in which data is stored for each item in time series can be performed by a simple interface provided by the data set class 105 and the cursor class 106. Can be programmed using

Embodiment 2 Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 6 shows development target software 111 to be developed in the second embodiment.
FIG. 3 is a diagram showing the configuration of FIG. In this figure, parts corresponding to the respective parts in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted. In FIG. 6, a water distribution management measurement item class 121 is newly added. The water distribution management measurement item class 121 is a subclass defined in the same manner as the water distribution management measurement item class 113, inherited from the item class 103 in the monitoring control system framework 101. Note that the water distribution management measurement item class 121 performs a different calculation process from the water distribution management measurement item class 113.

Also, the water distribution management weighing item class 121
