Embodiment 1 FIG.
1 is a block diagram showing a configuration of a facility monitoring system according to Embodiment 1 of the present invention. In the facility monitoring system, a field device 1, a controller 2, a central monitoring controller 3, a display device 4, and an engineering device 5 are connected via a communication line. 2A is a block diagram showing the configuration of the central monitoring controller 3, FIG. 2B is a block diagram showing the configuration of the display device 4, and FIG. 2C is a block diagram showing the configuration of the engineering device 5. .
Specifically, the field device 1 is a data input / output device such as a sensor, an actuator, or an air conditioner installed in a facility, and a plurality of field devices 1 are usually installed.

  Data is input from the field device 1 to the controller 2. For example, indoor temperature data is input from a temperature sensor. The data input from the field device 1 to the controller 2 is defined as the data of the management point associated with the field device 1 defined by the engineering device 5 when the facility monitoring system is constructed. Be treated. The management point is a data management unit on the software, and data such as measured values such as temperature and control values are assigned. A plurality of control controllers 2 may be provided.

The central monitoring controller 3 collects management point data from the control controller 2, and includes a collection cycle changing unit 30, a management point data collection storage unit 31, and a management point data transfer unit 32.
When a collection cycle change command is input from the engineering device 5, the collection cycle changing unit 30 sets the data collection cycle of the management point selected by the engineering device 5 to a predetermined first cycle (for example, 1 second). change. Note that when a collection cycle change command is input from the engineering device 5 to return the data collection cycle to the original cycle, the collection cycle change unit 30 returns the data collection cycle to the original according to the collection cycle change command.

The management point data collection storage unit 31 collects data of the management points selected by the engineering device 5 from the controller 2 at a cycle defined by the collection cycle changing unit 30 and stores it as history data.
The management point data transfer unit 32 transmits the management point data stored in the management point data collection storage unit 31 to the display device 4 and the engineering device 5.
A plurality of central monitoring controllers 3 may be provided.

The display device 4 includes a monitor 40, a display output unit 41, and a capture storage unit 42.
The display output unit 41 creates, for example, a summary graph format screen using the management point data input from the central monitoring controller 3 and displays it on the monitor 40.
The capture storage unit 42 captures the screen displayed on the monitor 40 and stores the screen displayed on the monitor 40 itself.

The engineering device 5 includes a management point selection unit 50, an override switching unit 51, a collection cycle change unit 52, a management point data setting unit 53, a management point data collection unit 54, a management point comparison unit 55, a management point And a storage unit 56.
The management point storage unit 56 stores management points defined when the facility monitoring system is constructed. For example, as shown in FIG. 3, the management point identification number, the management point name, the management point type, and the like are stored in association with each management point. Management point types include analog input (AI), digital input (DI), analog output (AO), digital output (DO), and the like.

  The management point selection unit 50 selects an arbitrary management point to be checked from the management points defined and stored in the management point storage unit 56. The management point may be selected by the management point selection unit 50 automatically and sequentially selecting all management points, or the management point selection unit 50 displays a list of all management points on a monitor (not shown). May be accepted. FIG. 3 shows a state in which a flag indicating selection is set for the selected management point. Only one management point or a plurality of management points may be selected.

  At the start of the check, the override switching unit 51 outputs a mode switching command to the control controller 2 so that the management point data selected by the management point selecting unit 50 is in an override state. When the management point data in the controller 2 is overridden, not the data input from the field device 1 but the data designated by the management point data setting unit 53 of the engineering device 5 is assigned to the management point.

The collection cycle changing unit 52 outputs a collection cycle change command to the central monitoring controller 3 so as to change the data collection cycle of the management point selected by the management point selection unit 50 to the first cycle. The first cycle is set shorter than the cycle in which the management point data setting unit 53 described below sets management point data.
The management point data setting unit 53 sets data in the control controller 2 of the management point selected by the management point selection unit 50 at a predetermined second period. That is, the management point data setting unit 53 sets the management point data in the control controller 2 to the second regardless of the data (for example, temperature data in the case of a temperature sensor) indicated by the field device 1 associated with the management point. Set in the cycle. For this reason, the state or value indicated by the management point data in the controller 2 is apparently changed.

  The management point data collection unit 54 collects history data, which is management point data collected by the management point data collection storage unit 31, from the central monitoring controller 3, and a display screen captured by the capture storage unit 42 from the display device 4, respectively. To do. For example, as shown in FIG. 4, the history data is a list of time, management point identification number, management point name, management point status or value at the time, alarms, and the like.

  The management point comparison unit 55 compares the management point history data collected from the central monitoring controller 3 with the management point data set values performed by the management point data setting unit 53 on the control controller 2. Thereby, it is checked whether or not the data change of the management point in the control controller 2 can be normally acquired by the central monitoring controller 3, and the operation between the control controller 2 and the central monitoring controller 3 is confirmed. The management point data setting values performed by the management point data setting unit 53 for the control controller 2 are stored as a history in the management point storage unit 56 every time setting is performed. Reference is possible.

  After the management point data collection from the control controller 2 by the management point data collection storage unit 31 is completed, the override switching unit 51 outputs a mode switching command to release the override state, and the collection cycle changing unit 52 outputs a collection cycle change command to return the changed data collection cycle to the original cycle.

  The control controller 2, the central monitoring controller 3, the display device 4, and the engineering device 5 each have, for example, a processor and a memory, and each function is realized by the processor executing a processing program.

FIG. 5 is a timing chart showing an example of processing of the facility monitoring system according to Embodiment 1 of the present invention.
First, the management point selection unit 50 of the engineering device 5 selects an arbitrary management point to be checked from the management points defined and stored in the management point storage unit 56. Then, when a check start button (not shown) is pressed by an operator or when a preset check start time is reached, the check is started.

  When the check is started, the mode switching is performed so that the override switching unit 51 of the engineering device 5 sets the data of the management point selected by the management point selecting unit 50 to the control controller 2 at the timing T1. Outputs a command. As a result, the management point data selected by the management point selection unit 50 is overridden in the control controller 2. Note that the processing at timing T1 corresponds to an override switching step.

  Subsequently, at timing T2, the collection cycle changing unit 52 of the engineering device 5 changes the data collection cycle of the management point selected by the management point selection unit 50 to the first monitoring cycle with respect to the central monitoring controller 3. The collection cycle change command is output so that Thereby, the collection cycle changing unit 30 changes the data collection cycle of the management point selected by the engineering device 5 to the first cycle.

  Subsequently, at timing T3, the management point data setting unit 53 of the engineering device 5 sets management point data in the controller 2 that has been overridden by the mode switching command at timing T1. That is, the state or value of the management point indicated by the management point data in the controller 2 is apparently changed. The process at timing T3 corresponds to a management point data setting step.

Subsequently, at timing T4, the management point data collection storage unit 31 of the central monitoring controller 3 collects the data of the management point selected by the engineering device 5 from the control controller 2 and stores it as history data. Further, the capture storage unit 42 of the display device 4 captures and stores the screen displayed on the monitor 40.
The processes at the timing T3 and the timing T4 are periodically performed before the subsequent timing T5. In particular, the management point data collection by the management point data collection storage unit 31 uses the first cycle based on the collection cycle change command at the timing T2.

  Subsequently, at timing T 5, the management point data collection unit 54 of the engineering device 5 collects history data from the central monitoring controller 3 and a display screen captured from the display device 4. The process at timing T5 corresponds to a management point data collection step.

Subsequently, at timing T6, the override switching unit 51 of the engineering device 5 outputs a mode switching command to the control controller 2 so as to release the override state.
Subsequently, at timing T7, the collection cycle changing unit 52 of the engineering device 5 outputs a collection cycle change command to the central monitoring controller 3 so as to return the changed data collection cycle to the original cycle. This original cycle is generally set to, for example, about 1 minute in consideration of efficient monitoring control in the facility, the amount of data that can be stored in the central monitoring controller 3, and the like. Therefore, if the history data is created in the original cycle, it takes time to obtain the history data reflecting the management point data setting change by the management point data setting unit 53, and the time required for the management point check May be longer. For this reason, when the management point is checked, the collection period changing unit 52 temporarily changes the data collection period to a first period shorter than the original period, thereby reducing the time required for the check. Can do.

The management point comparison unit 55 of the engineering device 5 collects history data from the central monitoring controller 3 collected at the timing T5, and setting values of management point data performed by the management point data setting unit 53 on the control controller 2. Compare Thereby, it is checked whether or not the data change of the management point in the control controller 2 can be normally acquired by the central monitoring controller 3, and the operation check between the control controller 2 and the central monitoring controller 3, that is, the management point is checked. . This processing by the management point comparison unit 55 corresponds to a management point comparison step.
In this way, the management point check work is automated, and the load on the worker for the check work is reduced.
The history data collected at the timing T5 from the central monitoring controller 3 and the management point data setting values performed by the management point data setting unit 53 for the control controller 2 are displayed on a monitor (not shown). Alternatively, it may be printed and presented to the worker and checked by the worker.

  Further, the display screen from the display device 4 collected at the timing T5 is stored as image data in the management point storage unit 56 or another storage unit (not shown) included in the engineering device 5. The image data stored in this manner is used as, for example, an attached material of a check result performed by the management point comparison unit 55. In addition, when a defect or the like occurs in the facility monitoring system later, it is possible to confirm the display contents using the display screen at the time of check.

Here, the case where the management point to be checked is of the AI type in the processing described with reference to FIG. 5 will be roughly described. In this case, the management point data setting unit 53 of the engineering device 5 changes the value of the management point of the AI type in the control controller 2 to a value between the upper limit value and the lower limit value in the second period. Then, the management point comparing unit 55 checks whether the value of the management point data of the AI type indicated in the history data from the central monitoring controller 3 has changed as the management point data setting unit 53 has changed. .
In particular, for AI type management points for which analog upper / lower limit monitoring is performed, the management point data setting unit 53 sets the second cycle (in FIG. 6) so as to straddle the upper limit warning value and the lower limit warning value as shown in FIG. Change the value every 2 seconds). Then, the management point comparison unit 55 checks whether or not an alarm appears in the history data from the central monitoring controller 3.

The case where the management point to be checked is a DI type will be roughly described. In this case, the management point data setting unit 53 of the engineering device 5 switches and changes the ON / OFF (operation / stop) state of the management point of the DI type in the control controller 2 in the second cycle. Then, the management point comparison unit 55 determines whether the ON / OFF state of the management point of the DI type indicated in the history data from the central monitoring controller 3 is switched as if the management point data setting unit 53 has changed. To check. Note that the management point comparison unit 55 can also check whether the integrated value of the number of operations has changed by switching the ON / OFF state by the management point data setting unit 53 a plurality of times.
In particular, in the case of a DI type management point for alarm, the management point comparison unit 55 checks whether or not it appears as an alarm in the history data from the central monitoring controller 3.

  As described above, according to the facility monitoring system according to the first embodiment, the management point data setting unit 53 sets the management point data that has been overridden in the controller 2. Then, the management point data collection unit 54 collects the history of management point data collected from the control controller 2 by the central monitoring controller 3 from the central monitoring controller 3. The management point comparison unit 55 compares the history collected by the management point data collection unit 54 with the setting made by the management point data setting unit 53 for the management point data in the control controller 2, whereby the control controller 2. It is checked whether or not the data change of the management point at can be normally acquired by the central monitoring controller 3. In this way, the operation check between the control controller 2 and the central monitoring controller 3 can be automated, and the load on the worker involved in the management point check work can be reduced.

In the above, the management point data setting unit 53 sets the management point data in the controller 2 and the management point data collection storage unit 31 collects the management point data from the controller 2 periodically. The case where the management point is checked was shown. However, the management point data setting by the management point data setting unit 53 may be performed only once. In this case, the management point data collection by the management point data collection storage unit 31 may be performed at an arbitrary timing after the setting process by the management point data setting unit 53, and is not necessarily performed at the cycle instructed by the collection cycle changing unit 52. There is no need. Therefore, the collection cycle changing unit 52 may be omitted.
Also, in the above, the management point data collection cycle by the management point data collection storage unit 31 is changed to a cycle shorter than the management point data setting cycle by the management point data setting unit 53 by the action of the collection cycle changing unit 52. It was decided. Thereby, a more reliable check can be performed. However, if the default data collection cycle of the management point data collection storage unit 31 is shorter than the data setting cycle of the management point data setting unit 53, it is not always necessary to change the data collection cycle. Further, the management point can be checked even if the management point data collection cycle by the management point data collection storage unit 31 is slightly longer than the management point data setting cycle by the management point data setting unit 53. From this point of view, the collection period changing unit 52 may be omitted.

Embodiment 2. FIG.

Further, description of matters already described in the first embodiment will be omitted or simplified as appropriate.

  The central monitoring controller 3 assigns a control value for controlling the field device 1 to the corresponding management point and outputs it to the control controller 2. Such a control value is calculated, for example, by the central monitoring controller 3 according to the control program for the field device 1.

The control controller 2 controls the field device 1 based on the control value indicated by the management point data input from the central monitoring controller 3. The controller 2 includes an input cycle changing unit 20, a management point data storage unit 21, and a management point data transfer unit 22.
When an input cycle change command is input from the engineering device 5, the input cycle changing unit 20 sets a cycle in which the management point data selected by the management point selecting unit 50 of the engineering device 5 is input from the central monitoring controller 3. Change to 1 cycle. When an input cycle change command is input from the engineering device 5 so as to return the input cycle to the original cycle, the input cycle change unit 20 returns the data input cycle according to the input cycle change command.

The management point data storage unit 21 stores, as history data, management point data input from the controller 2 at a cycle defined by the input cycle changing unit 20.
The management point data transfer unit 22 transmits the management point data stored in the management point data storage unit 21 to the engineering device 5.

FIG. 8 is a timing chart showing an example of processing of the facility monitoring system according to Embodiment 2 of the present invention.
As in the first embodiment, first, the management point selection unit 50 of the engineering apparatus 5 selects an arbitrary management point to be checked from the management points defined and stored in the management point storage unit 56. To do. Then, when a check start button (not shown) is pressed by an operator or when a preset check start time is reached, the check is started.

  When the check is started, at timing T10, the override switching unit 51 of the engineering device 5 sets the management point data selected by the management point selecting unit 50 to the override state with respect to the central monitoring controller 3. A switching command is output. As a result, the management point data selected by the management point selection unit 50 is overridden in the central monitoring controller 3. Note that the processing at timing T10 corresponds to an override switching step.

  Subsequently, at timing T <b> 20, the collection cycle changing unit 52 of the engineering device 5 changes the data input cycle of the management point selected by the management point selecting unit 50 to the control controller 2 to the first cycle. The input cycle change command is output. Thereby, the input cycle changing unit 20 changes the data input cycle of the management point selected by the engineering device 5 to the first cycle.

  Subsequently, at timing T30, the management point data setting unit 53 of the engineering device 5 sets management point data in the central monitoring controller 3 that has been overridden by the mode switching command at timing T10. That is, the state or value of the management point indicated by the management point data in the central monitoring controller 3 is apparently changed. Note that the processing at timing T30 corresponds to a management point data setting step.

Subsequently, at timing T40, the management point data storage unit 21 of the control controller 2 inputs the data of the management point selected by the engineering device 5 from the central monitoring controller 3 and stores it as history data. Further, the capture storage unit 42 of the display device 4 captures and stores the screen displayed on the monitor 40.
Processing at timing T30 and timing T40 is periodically performed before the subsequent timing T50. For the management point data setting by the management point data setting unit 53, the second cycle is used. Further, for the management point data input by the management point data storage unit 21, the first cycle based on the input cycle change command at the timing T20 is used.

  Subsequently, at timing T <b> 50, the management point data collection unit 54 of the engineering device 5 collects history data from the controller 2 and a display screen captured from the display device 4. Note that the processing at timing T50 corresponds to a management point data collection step.

Subsequently, at timing T60, the override switching unit 51 of the engineering device 5 outputs a mode switching command to the central monitoring controller 3 so as to release the override state.
Subsequently, at timing T <b> 70, the collection cycle changing unit 52 of the engineering device 5 outputs an input cycle change command to the control controller 2 so as to return the changed data input cycle to the original cycle. As described in the first embodiment, when the management point is checked, the data input cycle is temporarily changed to the first cycle shorter than the original cycle, thereby reducing the time required for the check. Can be planned.

The management point comparison unit 55 of the engineering device 5 collects history data from the control controller 2 collected at timing T50, and setting values of management point data set by the management point data setting unit 53 for the central monitoring controller 3. Compare Thereby, it is checked whether or not the data change of the management point in the central monitoring controller 3 is normally reflected in the control controller 2, and the operation check between the control controller 2 and the central monitoring controller 3, that is, the management point is checked. . This processing by the management point comparison unit 55 corresponds to a management point comparison step.
In this way, the management point check work is automated, and the load on the worker for the check work is reduced.
The history data from the controller 2 collected at the timing T50 and the setting values of the management point data set by the management point data setting unit 53 for the central monitoring controller 3 are displayed on a monitor (not shown). Alternatively, it may be printed and presented to the worker and checked by the worker.

  In the first embodiment, the management point data setting unit 53 sets management point data for the control controller 2, and the management point data collection unit 54 collects history data from the central monitoring controller 3. On the other hand, in the second embodiment, as described above, the management point data setting unit 53 sets management point data for the central monitoring controller 3, and the management point data collecting unit 54 collects history data from the control controller 2. To do.

  Further, the display screen from the display device 4 collected at the timing T50 is stored as image data in the management point storage unit 56 or another storage unit (not shown) included in the engineering device 5. The image data stored in this manner is used as, for example, an attached material of a check result performed by the management point comparison unit 55. In addition, when a defect or the like occurs in the facility monitoring system later, it is possible to confirm the display contents using the display screen at the time of check.

  Here, the case where the management point to be checked is the AO type in the above-described processing described with reference to FIG. 8 will be roughly described. In this case, the management point data setting unit 53 of the engineering device 5 changes the value of the management point of the AO type in the central monitoring controller 3 in the second cycle. Then, the management point comparison unit 55 checks whether the value of the management point of the AO type indicated in the history data from the control controller 2 has changed as the management point data setting unit 53 has changed.

  The case where the management point to be checked is the DO type will be roughly described. In this case, the management point data setting unit 53 of the engineering device 5 switches and changes the ON / OFF state (start / stop state) of the DO type management point in the central monitoring controller 3 in the second cycle. Then, the management point comparison unit 55 checks whether the ON / OFF state of the management point of the DO type indicated in the history data from the control controller 2 is switched as if the management point data setting unit 53 has changed. To do.

In particular, regarding DO type management points for which start / stop failure monitoring and status mismatch alarm output are performed, at the time of the check, the DI type management point that is paired with the DO type management point is also overridden and controlled. By switching the ON / OFF state of the management point of the DI type in the controller 2 by the management point data setting unit 53, it is also checked whether an alarm at the time of starting / stopping failure or state mismatch appears.

Check No. 1 In step 10, the check is performed by switching the ON / OFF state of the DO type management point and the DI type management point paired with the management point. In FIG. 9, ON or OFF underlined indicates that the ON / OFF state is switched by the management point data setting unit 53. If the double underlined ON or OFF is a DO type management point, the ON / OFF state is switched in association with the switching of the ON / OFF state in the central monitoring controller 3 of the management point. Indicates Similarly, if the double underlined ON or OFF is a DI type management point, the ON / OFF state is switched in association with the switching of the ON / OFF state in the control controller 2 of the management point. Indicates

It was. Thereby, a more reliable check can be performed. However, if the default data input cycle of the management point data storage unit 21 is shorter than the data setting cycle of the management point data setting unit 53, it is not necessarily changed. Further, the management point can be checked even if the management point data input cycle by the management point data storage unit 21 is slightly longer than the management point data setting cycle by the management point data setting unit 53.
