Description

The present invention relates to a method and an apparatus for assisting an operator who is in charge of operation of various facilities including air conditioning facilities and power generation facilities of buildings.
The equipment to be monitored and controlled according to the present invention is not particularly limited as long as it is a plant, apparatus, and machinery having a mechanism capable of monitoring and controlling in the monitoring control system, and a variety of equipment can be applied as operation target equipment.

  Buildings and factories are equipped with air-conditioning equipment and other power equipment that consumes a lot of energy and private power generation equipment (hereinafter simply referred to as “equipment”) that generates electrical energy. In recent years, it has become a social requirement to implement measures for energy-saving operation, particularly for the purpose of adjusting and reducing operating costs and carbon dioxide emissions.

For example, taking the operation of an air conditioner facility installed in a building as an example, it is generally known that the operation efficiency of this facility is the best during rated load operation and the efficiency decreases at low loads. On the other hand, the heat energy required for a comfortable living environment of humans, that is, the necessary heat load varies depending on the season and time zone. Therefore, when operating multiple air conditioner equipment found in many buildings and factories in parallel, when the thermal load is small, reduce the number of air conditioners to be operated and keep the remaining air conditioner equipment close to the rated load. In many cases, the driving method improves efficiency and enables energy-saving operation.

In a meeting place where people gather, the air conditioner is cooled and heated, but fresh air is taken in to prevent a lack of indoor CO2 concentration. Here, although the CO2 concentration varies depending on the number of people, etc., in general, a constant amount of air is often taken from outside air. Moreover, there are often cases where a certain amount of outside air is always taken in assuming the maximum capacity of the meetinghouse. In such a place, it is known that if the amount of outside air taken in is controlled so that the CO2 concentration is not increased beyond a specified value, the efficiency of the air conditioner operation increases and an energy saving effect is expected.
In general, the load on the electrical equipment supplied by the private generator varies greatly depending on the time and time zone. When the electrical load is low, the efficiency of the generator can be improved by reducing the number of operating units.

As described above, there are many cases where energy-saving operation is possible by operating the equipment with a high operating efficiency or stopping the operation of unnecessary equipment. For this reason, there are many cases in which equipment operators are required to perform more detailed equipment operations.
On the other hand, in many buildings and factories, a computer (hereinafter referred to as BEMS or the like) provided for monitoring and controlling equipment is often employed. The operator can monitor the state of a plurality of facilities and perform a driving operation via a monitor screen displayed by BEMS or the like.

Here, various screens on a monitor such as BEMS have been devised in order for an operator of the facility to accurately grasp the operation state of the monitored facility and facilitate the operation. For example, the operating state of each facility distributed on the premises, that is, the operating / stopped state of the facility, the temperature and power consumption, and the state of the device for taking in outside air with unique symbols and numerical values, etc. It is displayed and notified to the operator.
The operator confirms the equipment state and numerical values displayed on the monitor screen and operates the equipment. In addition, the operator can click on a unique symbol corresponding to the equipment displayed on the screen using an input device such as a mouse, or input numerical values and characters using an input device such as a keyboard. Start and stop, operation target value change setting, etc. are performed.

In many cases, the functions of BEMS, etc. include the function of displaying and notifying the equipment status to the operator, the operator operating the screen to specify the start or stop of the equipment, and target values such as temperature and rotation speed. There are many relatively simple ones, such as setting, and for example, detailed driving operations for realizing energy-saving operation must be performed by detailed screen operations while judging by the operators themselves, It was demanding technology and a lot of burden.

  Recently, in order to reduce the burden on the operator, a computer having a new operation management function (hereinafter referred to as an operation management computer) is introduced and connected to a BEMS or the like that is already installed and in operation. Attempts have been made to operate equipment with advanced new functions by utilizing the screen operation function of BEMS and the like while sharing the role between the management computer and the existing BEMS and the like.

The operation management computer mentioned here takes an image signal for displaying a screen such as BEMS, and performs image analysis to extract the operation state of the equipment. Furthermore, a mechanism is provided for performing setting control of equipment to be monitored and controlled by a method of generating a mouse or keyboard operation signal and operating a screen such as BEMS.
Here, there is an advantage that a new function can be easily added by a method of operating a screen such as an existing BEMS without remodeling the existing BEMS.
Details of this technique are disclosed in the following documents.

Patent Publication 2004-302990 Japanese Patent Application No. 2008-040740 Japanese Patent Application No. 2008-201640 Japanese Patent Application No. 2009-054356

However, it has been found that this method has the following problems.
The first problem is that there is an inevitable competition for screen operations. This is related to the system configuration method based on this method, but the operator of the equipment using BEMS and the like and the operator using the equipment automatic operation function of the operation management computer or the operation management computer (hereinafter referred to as operation The management computer equipment operation function, etc.) shares the screen display function and screen operation function (hereinafter referred to as screen function) such as BEMS that operates the target equipment. The screen function conflicts between the two.

For example, while the equipment operation function of the operation management computer is performing screen operations using screen functions such as BEMS, an operator such as BEMS performs operations for displaying another screen using the same screen functions. If you try to do so, you will be asked to display different screens, which causes contention.
That is, there is a problem that if the former makes a facility setting control operation while displaying the facility monitoring control screen and the latter makes a display request for a separate screen, the correct screen calling operation cannot be performed. For this reason, there is a demand for a simple and effective mechanism for preventing competition between an operator such as BEMS and the facility operation function of the operation management computer.

  The second problem is that a device necessary for a facility monitoring control function having an advanced function to be newly provided, for example, a new function for the purpose of addition, is a temperature sensor, a pressure sensor, or a set temperature raising / lowering setting device. In the case of requesting mounting such as, there is a case where it is not a target of the monitoring operation by existing BEMS or the like. In this case, it is necessary to attach to an existing BEMS or the like, but it has already been explained that this is extremely difficult. In order to provide a new function, it is a problem how to provide a means for easily taking in such shortage of facility information.

For this reason, various measures have been conventionally taken. For example, the following correspondence can be mentioned.
The first method is to add and remodel the functions for incorporating new equipment into the existing BEMS, etc., and to install the equipment that was the target of handling the existing BEMS and the newly installed equipment in the modified BEMS. It is a method of operating the equipment by centralized management by displaying on the same screen.
The second method is to provide a new monitoring and control device independent of the current BEMS, etc., and to monitor the facility by operating a dedicated monitoring control device dedicated to the additional target equipment and the conventional BEMS. This is a method for performing control.

Since the former involves remodeling work such as existing BEMS, much cost and work time are required. This is not a desirable method.
The latter is not a desirable method because the state of one piece of equipment is displayed on the screen of a different device, which requires a lot of operation work burden on the equipment operator.
Here, there is a demand for a mechanism that can implement the equipment state and setting control function to be added to the new monitoring control target while sharing the screen of BEMS, etc., without remodeling the existing BEMS. Is coming.

In the following, means for solving the above problems will be described.
(1) About the 1st subject The 1st mode and the 2nd mode can be considered as a means for solving the 1st subject. Each will be described below.

Here, a sub-system (hereinafter referred to as a supervisory control subsystem) having a function of adding a pop-up screen to a part of the equipment operation screen to be displayed on a monitor such as an existing BEMS, and an operation management computer are provided. And a subsystem (hereinafter referred to as an operation management subsystem) having a function of notifying information to the supervisory control subsystem.

Before the operation management subsystem uses the screen function of the supervisory control subsystem to start screen operations for equipment operation or during screen operations, this information is sent to the supervisory control subsystem operator. A part of the monitor display unit of the system is used to display the window in a so-called pop-up manner to notify. That is, it has a function that enables the operator of the supervisory control subsystem to quickly grasp the situation related to the screen operation performed by the operation management subsystem.

  In addition, the operator of the monitoring control subsystem adds input operation to the above pop-up screen, and prohibits or permits the operation of the operation management subsystem in advance. By providing a function for designating suspension or restart, contention of screen functions provided by the supervisory control subsystem is prevented.

Next, a monitoring control system according to a second aspect of the present invention is for solving the first problem by a method different from the first aspect, and corresponds to claims 4 and 5. Is.
Claims 4 and 5 are dedicated to providing this information to the supervisory control subsystem operator before the operation management subsystem starts performing the screen manipulation or during the screen manipulation. A method of notifying by displaying a lamp or a message on the display is taken. A function is provided for promptly notifying the operator of the monitoring control subsystem of the implementation status of the screen operation performed by the operation management subsystem.

In addition, by giving the display or message display an input function, the operator of the monitoring and control subsystem performs input operation on the display, thereby prohibiting or permitting the start of screen operation of the operation management subsystem in advance.

The so-called pop-up window is displayed to notify the operator.

For example, by additionally displaying the status of equipment not covered by existing BEMS etc. on the same BEMS etc. monitor screen, the operator of the supervisory control subsystem that configures existing BEMS etc. as the main element integrates different equipment. Monitoring on the same screen. Moreover, it becomes possible for the operator of the supervisory control subsystem to perform setting control for the equipment whose status is being displayed by performing an input operation on the additional screen.

The monitoring control system according to the fourth aspect of the present invention is a method different from the third aspect for solving the second problem, and corresponds to claims 8 and 9.
Claims 8 and 9 are directed to a monitoring apparatus having a function of taking in the state and a setting control function of equipment for equipment that is the same as or different from equipment targeted by the existing BEMS and the like in order to solve the second problem.

That is, the operator of the supervisory control subsystem uses a monitor of the supervisory control subsystem to make a conversation with the facility operation function of the operation management subsystem, for example, and requests the control execution device to cancel the screen operation. Or, a request for delaying the start of execution of the screen operation can be made, and it is possible to prevent contention of the screen operation related to the operation of the facility.

Equipment operators usually pay attention to the screen displayed on the monitor to operate the equipment. Therefore, important operation information can be communicated while being displayed on the monitor. desirable. According to the present invention, it is possible to display important operation information on the monitor of the supervisory control subsystem by a very simple method by providing the supervisory control subsystem without modification of the existing BEMS or the like.

According to the second aspect of the present invention, according to the fourth or fifth aspect of the present invention, a dedicated display input device is provided in place of the monitor of the first or second or third aspect of the present invention. In addition to the functional state of the control execution device, the facility operator can transmit information from the operator to the operation management subsystem.
That is, the operator of the supervisory control subsystem has a conversation with the operation management subsystem using a dedicated display input device. For example, here, it is possible to make a request to cancel the operation of the screen operation to the operation management subsystem or request to delay the start of the execution of the screen operation, thereby preventing the competition of the screen operation related to the operation of the facility. .
This is effective when the operation management subsystem cannot display operation information on the monitor of the monitoring control subsystem.

According to the third aspect of the present invention, the operator of the supervisory control subsystem according to the invention of claim 6 or claim 7 determines the equipment state notified from the monitoring device without intervening program processing such as existing BEMS. This can be grasped by a method of additionally displaying on the monitor screen of the monitoring control subsystem. The operator of the supervisory control subsystem can perform setting control of the operation state of the facility by designating this display content.
That is, here, it is possible to easily incorporate information relating to the equipment state notified from the monitoring device into the monitoring control target even for the equipment that is not monitored by the monitoring control subsystem using the existing BEMS or the like. is there.

Operators of the supervisory control subsystem usually perform equipment operation operations paying attention to the screen displayed on the monitor. Therefore, important operation information is displayed by inputting it while displaying it on the monitor. It is desirable that equipment with a function to perform monitoring and control on the same screen.
According to the present invention, it is possible to display important facility operation information on a monitor by a very simple method without changing a screen or modifying a program of an existing BEMS or the like constituting a monitoring control subsystem.

  Hereinafter, embodiments of a monitoring control system and a monitoring control method according to the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number, etc. shown in the following examples.

(Corresponding to Claims 1, 2 and 3)
1 shows an example of a monitoring control apparatus of the present invention according to a first embodiment.
This will be described below with reference to FIGS.
FIG. 1 is a diagram illustrating an example of a monitoring control apparatus according to the present invention.
In the configuration example of FIG. 1, the monitoring control device 100 includes a monitoring control subsystem 10 and an operation management subsystem 30. The supervisory control subsystem 10 is generally a system installed adjacent to the BEMS or the like, and is connected to the supervisory control target equipment 200 to perform state monitoring of the supervisory control target equipment 200 and setting control of operation condition change. In addition to a method for directly transmitting and receiving electrical signals for facility status display and setting control between the monitoring control subsystem 10 and the monitoring and control target facility 200, it is converted into communication packet data via a communication network. There is also a method of doing this, but the means is not limited here.

The monitoring control subsystem 10 and the operation management subsystem 30 are connected via a wide-area communication network 300.
In FIG. 1, the operation management subsystem 30 is connected to one monitoring control subsystem 10 via the communication network 300, but may be configured to be connected to a plurality of different monitoring control subsystems 10.
It goes without saying that the monitoring control subsystem 10 and the operation management subsystem 30 may be connected via a local network such as a LAN instead of the wide area communication network 300.

The monitoring control target equipment 200 is not particularly limited, and can be applied to various equipment such as building equipment of a building or factory, that is, power receiving / transforming equipment, air conditioning equipment, plant equipment, and the like. Here, a sensor for notifying the operation state of the facility to an external device and a setting control device for changing the state of the facility from the outside are provided. The supervisory control subsystem 10 is connected to these sensors and setting control devices by a method of transmitting and receiving signals.

The communication network 300 is not particularly limited. Here, in addition to a wide-area broadband such as a communication network using an optical fiber or a coaxial cable, various narrow bands such as ISDN using a metal wire, and PHS are also included. Any method can be used, such as a wireless method or a network function based on other communication methods.

Hereinafter, first, each component of the monitoring control subsystem 10 and each component of the operation management subsystem 30 will be described. Next, the operation management subsystem 30 performs operation management on the operators of the monitoring control subsystem 10. A mechanism for notifying information related to facility operation using a part of the screen of the subsystem 30 will be described.

(1) Description of each component of the supervisory control subsystem 10 The supervisory control subsystem 10 has a supervisory control basic function 20 as a core, and has an input device data processing unit 11, an image data extraction processing unit 12, and image data distribution. A processing unit 13, a signal superimposing display processing function 14, and a transmission processing unit 18 are provided.

Here, the monitoring function basic function 20 includes an equipment data input / output unit 21, an equipment monitoring control processing unit 22, an image display processing unit 23, a monitor 24, and an input device 25. Unit 15, signal generation unit 16, and signal synthesis processing unit 17.
The monitoring control basic function 20 has the same function as a general BEMS and the like, captures the state of the monitoring control target equipment 200 and displays it on the monitor 24, and a screen executed by the equipment operator using the input device 25. Based on the operation, a setting control process for the monitoring control target facility 200 is performed.

Here, the equipment data input / output unit 21 takes in a signal indicating the equipment state from a sensor provided in the monitoring control target equipment 200 and is notified from the equipment monitoring control processing unit 22, for example, start and stop of equipment, and further an air conditioner Based on the equipment setting control data such as raising or lowering the temperature setting in the equipment, setting control for changing various operating conditions is performed via the setting control device provided in the monitoring control target equipment 200.
The equipment monitoring control processing unit 22 takes in the state of the monitoring control target equipment 200, and generates display symbols that are screen display data for visualizing the equipment state and data indicating the display position based on the taken-in data. Here, if the operator operates the input device 25 to specify a specific position on the screen, the facility specified by the input device and the type of setting control specification are specified from the position on the screen to be notified.

In other words, the equipment monitoring control processing unit 22 displays the equipment state and stores the display position on the screen for each piece of equipment. In this state, if a notification of the position on the screen is received from the input device. This is because the corresponding equipment can be immediately identified.
Here, the image display processing unit 23 generates an image signal called a so-called RGB signal in order to display a screen on the monitor based on the image data generated by the facility monitoring control processing unit 22.
The monitor 24 receives the image signal generated by the image display processing unit 23 and displays a screen.

The input device 25 may be a pointing device such as a mouse or a keyboard. A so-called touch panel that notifies the position on the screen by touching the fingertip of the hand with the screen, or a so-called lie and pen that notifies the position on the screen by touching a pen-like instrument on the screen may be used. Furthermore, there is no particular limitation as long as it has a function of designating and notifying the position on the screen.
The signal superimposing display processing function 14 is a function that plays an important role of the present invention, and displays a message and an image generated by the equipment monitoring control processing unit 31 for a part of the image signal generated by the image display processing unit 23. This is replaced with the image signal and notified to the monitor 24. At the same time, information indicating the position on the monitor 24 where the image data generated by the equipment monitoring control processing unit 31 of the operation management subsystem 30 is displayed as a partial screen is also generated.

Here, in the data generation unit 15, in addition to the message data from the operation management subsystem 30, data including information necessary for displaying the display position and color on the screen, the display character font, the display character size, and the like is displayed. In response to this, image data is generated and delivered to the signal generation unit 16.
The message data here refers to a data string in a so-called character code format indicating characters and numerical values, and the data generation unit 15 converts them into image data in a bitmap format. At the same time, the input device data processing unit 11 is notified of information indicating the position on the screen where the image data for superimposition is displayed on the monitor 24.

In the signal generation unit 16, a so-called horizontal synchronization signal and vertical synchronization signal, which are generally used for displaying a screen on a monitor, generated by the image display processing unit 23 and notified through the signal synthesis processing unit 17, are used. In addition, an image signal for displaying the image data generated by the data generation unit 15 on the screen on the monitor 24 is generated.
Here, the configuration of the image display signal will be described.
Since there are many manuals and standards for image display signals, only the main points according to the present invention will be described here.
The image display signal is configured in accordance with a general standard for display on the monitor 24, and the most popularly used for computer monitor display is an independent red, called RGB signal, It consists of green, blue, horizontal sync and vertical sync signals.

The display surface of the monitor 24 is divided into a fixed number of meshes. The standard indicating the degree of mesh division is called resolution. Although the resolution varies depending on the specifications of the individual monitor, for example, the one that divides the length into 1024 and the width into 1280 is called SXGA resolution. In this case, one screen is composed of display units called 1024 × 1280 independent pixels.
By individually specifying the display method of the red element, the green element, and the blue element for each of these pixels, the hue of each pixel is determined, and one screen is configured from the set of pixels.

Here, the RGB image signals are transmitted with image information constituting pixels in a time division manner for each pixel using independent communication lines indicating red, green, blue, horizontal synchronization and vertical synchronization signals. A mechanism is adopted.
That is, the horizontal synchronization signal is composed of a continuous pulse signal that repeats on / off of the number of pixels arranged in the horizontal direction using one line, and the vertical synchronization signal is composed of the horizontal synchronization pulse signal using another line. A configuration is adopted in which a signal of one pulse is generated every time signal generation for the number of pixels arranged in the horizontal direction is completed.

The remaining three lines include signals for transmitting red signal, green signal, and blue signal data constituting data for one pixel in synchronization with the horizontal synchronizing pulse signal.
For example, in an RGB image signal of SXGA resolution, one vertical synchronizing signal pulse is generated every time 1280 horizontal synchronizing signals are generated, and as a result, every time 1024 vertical synchronizing signals are generated, all of one screen is shown. The RGB image data of the pixels are transmitted.

Therefore, on the screen displayed on the monitor 24, the signal transmission timing of the pixel corresponding to a specific position on the screen can be determined by counting the number of pulses of the horizontal synchronization signal and the vertical synchronization signal. By changing the signals indicating the red element, the green element, and the blue element transmitted at this timing, the display content of the screen can be partially changed.
That is, an arbitrary partial screen can be superimposed on a so-called monitor screen by selectively generating an image display signal in accordance with the synchronization signal.

In the configuration of FIG. 1, the partial image distributed from the equipment monitoring control processing unit 31 of the operation management subsystem 30 to the monitoring control subsystem based on the RGB image signal generated by the image display processing unit 23 of the monitoring control subsystem. Although the method of partial replacement with data has been described, a method of displaying partial image data to be distributed from the equipment monitoring control processing unit of the operation management subsystem 30 to the monitoring control subsystem can be considered by other methods.

For example, there is a device that displays a screen with a signal of a method called a composite image signal or a component image signal instead of the RGB image signal. Again, since it is composed of a sync signal and a signal indicating a red element, a green element, and a blue element, a method of implementing the present invention in these systems can be easily considered.
In another example, the RGB image signal generated by the image display processing unit 23 of the monitoring control subsystem 10 is temporarily converted into digital image data, and then the equipment monitoring control processing unit 31 of the operation management subsystem 30 performs the monitoring control sub. A method is conceivable in which after partial image data distributed to the system is replaced and edited, the image data is reconverted into an RGB image signal and notified to the monitor 24.
In the present invention, any method may be used as long as the partial image data distributed from the equipment monitoring control processing unit 31 of the operation management subsystem 30 to the monitoring control subsystem is superimposed on the screen generated by the image display processing unit 23 of the monitoring control subsystem. Any display means can be used.
In the above example, based on the RGB image signal generated by the image display processing unit 23 of the monitoring control subsystem, it is based on partial image data distributed from the equipment monitoring control processing unit 31 of the operation management subsystem 30 to the monitoring control subsystem. Although the method of partially changing an image has been described, it is also conceivable to generate an image signal that displays both images mixed by a method of combining elements of both image signals, instead of partially changing the image signal.

In the signal synthesis processing unit 17, based on the image display signal generated by the image display processing unit 23 and the image signal generated by the signal generation unit 16, for the display range of the display signal of the signal generation unit, the image signal of the signal generation unit In other cases, an image display signal generated by the image display processing unit 23 is used to generate an image signal to be displayed on the monitor.

Next, the description returns to the description of the present invention.
The input device data processing unit 11 captures a cursor display position that is arbitrarily moved on the screen by operating the input device and a keyboard input value input on the screen, and a position on the screen by a mouse click operation or the like. If the designation is made, it is determined whether it is a screen displayed by the generation of the image display processing unit 23 or a screen displayed by the generation of the signal superimposing display processing unit 17.

That is, the input device data processing unit 11 receives and stores data notification indicating the display position and display range of the superimposed display screen generated simultaneously with the generation of the data for superimposition from the data generating unit 15.
In addition, it has a function of receiving a notification of image data including a cursor image display generated by the image display processing unit 23 from the image data extraction processing unit 12 and detecting a position on the screen where the cursor image is displayed. is there. In order to detect the position on the screen where the cursor image is displayed, a cursor symbol displayed in a specific shape on the screen may be found.

When the operator operates the input device 25 to specify a position on the screen and performs a mouse click operation, for example, the input device data processing unit 11 determines the display position of the cursor that moves on the screen by operating the input device. Then, it is determined whether this is the position of the screen displayed by the generation of the superimposed display processing unit 17. If the position on the screen specified by the input device is the position to be displayed by the generation of the superimposed display processing unit 17, the position data on this screen is notified to the equipment monitoring control processing unit 31 of the operation management subsystem 30, and so on. If not, it notifies the equipment monitoring control processing unit 22 of the equipment monitoring subsystem 10.

FIG. 2 is an example 500 of an equipment operation screen displayed by the monitoring control basic function 20.
FIG. 3 shows an example 501 of a partial screen for information display based on an image signal generated by the signal generator 16. FIG. 4 shows an example 502 of a composite display screen based on an image signal from which the signal is output from the signal synthesis processing unit 17.

The image data extraction processing unit 12 also performs various types of processing for reducing the amount of distribution data including data compression processing for distributing the image data of the image data display processing unit 23 via the communication network. For example, the difference with the image data distributed last time is extracted, only the difference data is distributed, and further the image compression is combined to generate distribution data.

Here, it is sufficient that the image data generated by the image display processing unit 23 is correctly notified to the operation management subsystem 30, and the means for distributing image data is not particularly limited.
The image data distribution processing unit 13 distributes the image data generated by the image data extraction processing unit 12 to the operation screen reproduction processing unit 33 of the operation management subsystem 30.
The transmission processing unit 18 performs data distribution between the transmission processing unit 34, the monitoring control subsystem 10 and the operation management subsystem 30.

(2) Description of Each Component of the Operation Management Subsystem 30 The operation management subsystem 30 includes an equipment management control processing unit 31, an input device data generation processing unit 32, an operation screen reproduction display processing unit 33, and a transmission processing unit 34. ing.
The facility management control processing unit 31 has a function for maintaining and operating the monitoring control target facility 200 in a target state. Here, first, in order to grasp the equipment state, image data in a format called bmp that displays the equipment state distributed from the supervisory control subsystem 10 is taken and subjected to image analysis, and the equipment whose state is displayed with symbols is displayed. Based on the color and shape, the state indicating that the facility is operating or stopped is converted into a value of 1 or 0, and the state of the facility displayed numerically is converted into data in a format called CSV.

Next, the equipment monitoring control processing unit 31 monitors the equipment state using the grasped equipment state value. If the equipment monitoring control processing unit 31 determines that the equipment state needs to be changed, data indicating the equipment and the change instruction is generated.
For example, in the case of the monitoring and control target equipment 200 operated within a certain target temperature range, the equipment management control processing unit 31 is in a deviation state in which the equipment temperature displayed on the screen for displaying the equipment status is higher than the target range. Is detected, setting control instruction data for lowering the facility temperature is generated. Conversely, if a deviation state that falls below the target range of the equipment is detected, setting control instruction data for increasing the equipment temperature is generated.

Based on the equipment notified by the equipment management control processing section 31 and its change instruction data, the input device data generation processing section 32 calls the equipment setting control screen on the monitor of the monitoring control subsystem and performs the equipment setting control operation. Generate screen operation data to do. For example, if setting control instruction data for lowering the equipment temperature is received from the equipment management control processing unit 31, a change setting input device for lowering the equipment temperature by calling the equipment temperature setting control screen of the monitoring control subsystem Generate operation data.

On the contrary, if setting control instruction data for raising the equipment temperature is received from the equipment management control processing unit 31, a change for raising the equipment temperature by calling the equipment temperature setting control screen of the supervisory control subsystem Generate input device operation data for settings.
The operation screen reproduction display processing unit 33 performs a process of decompressing the compressed image data distributed from the image data distribution processing unit 13 of the monitoring control subsystem 10 and restoring it to bmp format image data, as a change image. By overwriting the distributed image on the image data in the bmp format, the image data generated by the image display processing unit 23 of the monitoring control subsystem 10 is processed to be faithfully reflected in the operation management subsystem 30.
The transmission processing unit 34 transmits and receives data between the operation management subsystem 30 and the monitoring control subsystem 10.

(3) Example of processing operation of supervisory control device Here, the operator of the supervisory control subsystem 10 uses the monitor 24 for displaying a screen related to the supervisory control target equipment 200 while operating the equipment. The operation of the monitoring control apparatus 100 will be described by taking as an example a case where the subsystem 30 facility monitoring control processing unit 31 performs automatic operation of the monitoring control target facility 200 using the same monitor 24 of the monitoring control subsystem 10. .
First, a process performed by the operator of the monitoring control subsystem 10 during the operation of the facility using a screen related to the monitoring control target facility 200 will be described.

The state of the monitoring target equipment 200 is input by the equipment data input processing unit 21, bmp format data for displaying a screen is generated by the equipment monitoring control processing unit 22, and delivered to the image display processing unit to be an image called RGB It is converted into a display signal. The RGB image display signal is input to the signal synthesis processing unit 17, and the image display signal generated by the signal generation unit 16 is partially overlapped and delivered to the monitor 24 for display. When there is no image signal generated by the signal generation unit 16, only the image data generated by the image display processing unit 23 is displayed on the monitor 24.

Next, a case where the operation management system starts the facility operation of the monitoring control target facility 200 will be described.
The equipment monitoring control process 31 of the operation management subsystem 30 first informs the operator of the monitoring control subsystem 10 that the screen is occupied when grasping the state of the monitoring control target equipment 200 and performing setting control. Start with that. For this reason, the message data is distributed from the equipment monitoring control processing 31 to the data generation unit 15 of the signal superimposing display processing function 14 via the transmission processing unit 34, the communication network 300, and the transmission processing unit 18.

The data generation unit 15 converts the character code data constituting the message data into image data in the bmp format and delivers it to the signal generation unit 16.
At the same time, the input device data processing unit 11 is notified of data indicating the display position and display range of the image data delivered to the signal generation unit 16.
Here, in the signal synthesis processing unit 17, the image signal generated by the signal generation unit 16 is preferentially superimposed on the image signal generated by the display processing unit to generate an image signal.

As a result, the monitor 24 displays the screen of the superimposition data 16 on the image generated by the image display processing unit 23 in a so-called pop-up format, so that the equipment monitoring control processing unit 31 is provided to the operator of the monitoring control subsystem. The message to be notified can be explicitly notified.
Here, the operator of the monitoring control subsystem can respond to the facility monitoring control processing unit 31 using the input device 25.
That is, if the message included in the pop-up screen inquires whether or not the equipment operation started by the equipment monitoring control process 31 is accepted and displays a “Yes” or “No” selection button, the monitoring is performed. The operator of the control subsystem can select and specify any button.

If the operator moves the cursor to any position of the pop-up “Yes” or “No” button by the input device 25 and selects and designates it by a mouse click operation or the like, the input device data processing unit 11 firstly The cursor display position moved by the input device is determined. On the other hand, the input device data processing unit 11 stores the image display position and range received from the signal generation unit 16. If the position on the screen designated by the input device 25 using the cursor is within the position range of the pop-up screen, the designated position is notified to the equipment monitoring control processing unit 31. Here, if “Yes” is selected and designated, the equipment monitoring control process 31 is notified of information to be designated, and the equipment monitoring control process 31 starts automatic operation of the screen.

If “No” is selected, the equipment monitoring control process 31 is similarly notified of the information to be designated, and the equipment monitoring control process 31 stops the screen automatic operation.
FIG. 2 is an example of an equipment operation screen displayed by the monitoring control basic function 20.
FIG. 3 is an example of a screen that visualizes the image data generated by the data generation unit 15 in response to the notification from the equipment monitoring control processing unit 31.
FIG. 4 is an example in which the image data generated by the data generation unit 15 is displayed in a pop-up format in response to a notification from the facility monitoring control processing unit 31 on the facility operation screen displayed by the monitoring control basic function 20.

In the above-described embodiment, the equipment monitoring control processing 31 displays a message in a pop-up format on the monitor of the monitoring control subsystem, inquires the operator whether or not to accept the start of the screen operation, and sends a response from the operator to the equipment monitoring control. Although the conversation example for notifying the process 31 has been described, the present invention does not limit the contents of the conversation between the equipment monitoring control process 31 and the operator to the above example.

For example, when the operator of the monitoring control subsystem overlooks an abnormal state during the operation of the equipment, a method can be considered in which the equipment monitoring control processing 31 notifies the operator of information on alerting the abnormal state.
In addition, a method for realizing support for safe and effective facility operation by notifying the operator of desired operation operation guidance for efficient operation of the facility by pop-up display and further conversation is also conceivable. .

FIG. 5 is a diagram illustrating an example of the monitoring control device 100 of the present invention.
In the configuration example of FIG. 5, the monitoring control device 100 includes a monitoring control subsystem 10 and an operation management subsystem 30.
Here, the functional operation of the monitoring control system 100 according to the second embodiment will be described while clarifying differences from the first embodiment.

(1) Differences in Configuration First, differences in components in the monitoring control subsystem 10 will be described.
The monitoring control subsystem 10 in the configuration of the second embodiment includes a display device 25 instead of the signal superimposing display processing function 14 in FIG. 1 of the first embodiment.
The display device 25 includes a display unit 26 that displays a message and a push button unit 27. The display unit 26 is configured by, for example, a liquid crystal display and displays message data and image data, and the push button unit 27 is configured by arranging a plurality of contacts that are normally turned off and turned on when the operator presses them.

Next, the difference of the component in the equipment monitoring control processing part 31 of the operation management subsystem 30 is demonstrated.
Although the equipment monitoring control processing unit 31 in the configuration of the second embodiment has the same core function for maintaining and operating the equipment 200 to be monitored and controlled in a target state, the operator does not change to the operation management subsystem 30 here. In order to notify, instead of the input device operation information notified through the input device data processing unit 11 in the first embodiment, the second embodiment has a function of processing push button information provided on the display device 26.

(2) Example of processing operation of supervisory control device Similar to the description in the first embodiment, the operator of the supervisory control subsystem 10 uses the monitor 24 to display a screen related to the supervisory control target equipment 200. In the case where the operation management subsystem 30 facility monitoring control processing unit 31 performs the automatic operation of the monitoring control target facility 200 using the same monitor 24 of the monitoring control subsystem 10 during operation, the monitoring control device The operation of 100 will be described.

First, a process performed by the operator of the monitoring control subsystem 10 during the operation of the facility using a screen related to the monitoring control target facility 200 will be described.
The state of the monitoring target equipment 200 is input by the equipment data input processing unit 21, image data for displaying a screen is generated by the equipment monitoring control processing unit 22, converted into an image signal by the image display processing unit, and the monitor 24. Will be displayed.
Next, a case where the operation management system starts automatic operation of the monitoring control target facility 200 will be described.

The equipment monitoring control processing 31 of the operation management subsystem 30 is data that indicates the screen occupation request to the operator of the monitoring control subsystem 10 before grasping the state of the monitoring control target equipment 200 and performing the setting control. Start by delivering. For this reason, by distributing and displaying message data or image data indicating a screen occupation request on the display device 25 from the equipment monitoring control processing 31 via the transmission processing unit 34, the communication network 300, and the transmission processing unit 18, the monitoring control is performed. The request contents of the equipment monitoring control processing unit 31 can be explicitly notified to the operator of the subsystem.

Here, the operator of the monitoring control subsystem can respond to the facility monitoring control processing unit 31 by pressing the push button 27 of the display device 25. That is, the message or image data displayed on the display of the display device 25 inquires whether or not the automatic operation started by the equipment monitoring control process 31 is accepted, and the selection of “Yes” or “No” is requested. If so, the operator of the monitoring control subsystem can select and specify any push button 27 of the display device 25.

If the operator selects and designates either the “Yes” or “No” push button 27 on the display device 25, the display device 25 notifies the facility monitoring control processing unit 31 of the type information of the pressed button. . If “Yes” is selected and designated, the equipment monitoring control process 31 starts an automatic screen operation.
If “No” is selected, the equipment monitoring control process 31 is similarly notified of the information to be designated, and the equipment monitoring control process 31 stops the screen automatic operation.

In the above example, an example in which the dedicated push button 27 is provided on the display device 25 has been described. However, the message content displayed on the display device 25 is changed to “Yes” and “No” for selection instead of the push button 27. A method is also conceivable in which both buttons are displayed on the display 26 and the selection content is specified by touching the display surface.

In the above embodiment, the equipment monitoring control process 31 displays a message on the display 26 of the display device 25 to inquire the operator whether to accept the screen operation start and to respond to the operator's response from the equipment monitoring control. Although the conversation example for notifying the process 31 has been described, the present invention does not limit the contents of the conversation between the equipment monitoring control process 31 and the operator to the above example.

For example, when the operator of the monitoring control subsystem overlooks an abnormal state during the operation of the equipment, a method can be considered in which the equipment monitoring control processing 31 notifies the operator of information on alerting the abnormal state.
In addition, safe and effective support for facility operation is realized by displaying desired operation guidance for efficient operation of the facility on the display device 25, notifying the operator and further having a conversation. A method for this is also possible.
