Description

  The present invention relates to an instrumentation console that is used in a process monitoring control system that monitors and controls a process manufacturing apparatus, and that displays and displays a trend graph.

  The process monitoring control system includes a process control device connected to a process manufacturing device and an instrumentation console. The process control apparatus performs feedback control, sequence control, process state monitoring, and the like, and controls various processes of the process manufacturing apparatus. The instrumentation console is used by the operator to monitor the process and has a function of creating a trend graph of the process manufacturing apparatus and displaying the process data.

  In a conventional instrumentation console, process data to be displayed is selected and registered in advance for each trend graph to be created, and the process data collected and accumulated based on the registered contents is displayed as a trend graph (for example, (See Patent Document 1). That is, process data that is not registered in the trend graph cannot be displayed.

  Therefore, even when an alarm is generated due to a failure in the process manufacturing apparatus, the process data up to the failure cannot be displayed unless the process data is registered. If all the process data is registered, there is no process data that cannot be displayed, but the registration process becomes complicated, and the possibility that process data that cannot be displayed due to omission of registration cannot be excluded. Furthermore, in order to display the trend graph in which the failed process manufacturing apparatus is registered, an operation of selecting a target trend graph from a large number of trend graphs becomes complicated.

  The cause of the alarm may be another process manufacturing apparatus related to the process manufacturing apparatus in which the alarm has occurred. In this case, it is necessary to confirm the process data of the process manufacturing apparatus in which an abnormality has occurred and the process data of the process manufacturing apparatus related to this process manufacturing apparatus, but these process manufacturing apparatuses are registered in the same trend graph. It is not always done. For this reason, in this case, an operation of displaying and confirming a plurality of trend graphs is necessary, and this operation is also complicated.

  In addition, in the conventional process monitoring control system, the collection of process data is always executed and is not stopped at an arbitrary timing. The collected process data is accumulated in a memory in a ring buffer format, and the process results are stored by storing the accumulated process data in an external storage device or the like. This method is effective for utilizing process data during normal operation. However, if the process data is not saved normally due to a failure of the external storage device, etc., the process data at the time of occurrence of the abnormality stored in the memory will be overwritten, and the situation at the time of abnormality cannot be confirmed after the occurrence of the abnormality. There is a possibility.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of a process monitoring control system using an instrumentation console according to an embodiment of the present invention. The process monitoring control system includes a monitoring console 1 that performs a process monitoring operation of a process manufacturing apparatus, a process control apparatus 2 that performs process data collection and control calculation, and a control network 4. The monitoring console 1 is an instrumentation console according to this embodiment, and is connected to an external storage device 6. The external storage device 6 stores process data collected and accumulated by the monitoring console 1.

  The process control apparatus 2 is connected to process manufacturing apparatuses 3A, 3B, and 3C arranged at the plant site. Sensors 3A1, 3B1, 3C1, control valves 3A2, 3B2, 3C2, and electromagnetic valves 3A3, 3B3, 3C3 are attached to the process manufacturing apparatuses 3A to 3C, respectively. The sensors 3A1 to 3C1, the control valves 3A2 to 3C2, and the electromagnetic valves 3A3 to 3C3 are connected to the process control device 2 via the construction wiring 5.

  FIG. 2 is a diagram showing an internal configuration of the monitoring console 1 (instrumentation console) according to the present embodiment. The monitoring console 1 includes a display device 11 for displaying information, a computing device 12 for performing various computations, a storage device 13 for storing and managing various collected information, and an input / output device 14 for various interactions with the outside. . The monitoring console 1 collects process data from the process manufacturing apparatuses 3 </ b> A to 3 </ b> C via the input / output device 14 and accumulates it in the storage device 13.

  In the conventional monitoring console (instrumentation console), the process data of the sensors 3A1 to 3C1, the control valves 3A2 to 3C2, and the solenoid valves 3A3 to 3C3 connected to the process manufacturing apparatuses 3A to 3C are stored in advance in units of trend graphs. Selected and registered to collect and accumulate these process data. For this reason, when displaying process data on the monitoring console, the operator selects a trend graph in which the process data to be displayed is registered from a large number of trend graphs, and the process data is displayed. Operation was necessary.

  For this reason, when an alarm is generated from the process manufacturing apparatuses 3A to 3C, it is desired to immediately display process data relating to the process manufacturing apparatus in which the alarm has occurred, but since it is not registered, process data until immediately before the alarm is generated is collected. In some cases, it was not possible to display it, and it took time to select a trend graph. The process data stored in the storage device 13 is normally stored in the external storage device 6, but if it is not stored due to lack of capacity or a hardware failure, it is overwritten and an error occurs. There is a possibility that the process data will be lost and the situation at the time of occurrence of the abnormality cannot be confirmed.

  The present invention solves these problems, and specific contents of the invention will be described below. In the following description, as an example, it is assumed that the electromagnetic valve 3A3 of the process manufacturing apparatus 3A shown in FIG.

  3A to 3D are diagrams showing a flow of processing after alarm reception performed by the monitoring console 1 (instrumentation console). 3A shows a flow of alarm display processing, FIG. 3B shows a flow of trend graph display processing, FIG. 3C shows a flow of process data acquisition processing from feedback control information, and FIG. 3D shows process data acquisition processing from sequence control information. Shows the flow.

  FIG. 4 is a diagram showing a display example of a trend graph on the monitoring console 1 (instrumentation console). 4 also shows data movement between the display device 11 and the storage device 13, the process control device 2, and the external storage device 6 of the monitoring console 1. The display device 11 displays trend graphs 11B of various devices (sensors 3A1, 3B1, 3C1, control valves 3A2, 3B2, 3C2, and electromagnetic valves 3A3, 3B3, 3C3) of the process manufacturing apparatuses 3A to 3C.

  As shown in <1> of FIG. 4, the process data of the process manufacturing apparatuses 3 </ b> A to 3 </ b> C is directly transferred (copied) from the process data 13 </ b> D of the process control apparatus 2 to the process data 13 </ b> C of the storage device 13 of the monitoring console 1. By doing so, it is collected and accumulated in the monitoring console 1. The storage device 13 of the monitoring console 1 stores the transferred process data 13C in a time series order in tag units (control target units) for all process manufacturing apparatuses in the plant. The process data 13C, 13D includes a unique tag added to each of the control objects (sensors 3A1, 3B1, 3C1, control valves 3A2, 3B2, 3C2, and electromagnetic valves 3A3, 3B3, 3C3), and control objects at each time. Data is recorded. In the process data 13C and 13D shown in FIG. 4, codes (3A1, 3A2, 3A3, etc.) attached to the control target are used as the control target tags, and the data of the times T1 to T6 are shown in time series order.

  A process in which the monitoring console 1 displays an alarm after receiving the alarm will be described with reference to FIG. 3A.

  The process control device 2 includes a device that detects an abnormality when an abnormality is detected from devices (in this embodiment, a sensor, a control valve, and a solenoid valve) included in the process manufacturing devices 3A to 3C to be controlled. Generate an alarm from This alarm is transmitted to the monitoring console 1 via the control network 4 as an alarm generated by the process manufacturing apparatus.

  In the monitoring console 1, the input / output device 14 receives this warning in step 10A01. In subsequent step 10A02, the arithmetic unit 12 causes the display unit 11 to display an alarm display. In FIG. 4, an alarm display 11A indicating that the electromagnetic valve 3A3 of the process manufacturing apparatus 3A has failed is displayed on the display device 11.

  Conventionally, the process data collection / accumulation was not stopped when the alarm was displayed. However, in this embodiment, in order to prioritize the storage of the situation, as shown in <2b> in FIG. It is also possible to stop data collection / accumulation.

  In step 10A03 of FIG. 3A, it is determined whether or not to stop collecting and accumulating process data. This determination is made based on the stop rule information file 13E stored in the storage device 13. In the stop rule information file 13E, for example, in order to stop the collection and accumulation of process data such as stopping the collection and accumulation of process data when a signal from a specific device with high importance is interrupted. Judgment conditions (stop rules) are recorded. The stop rule information file 13E is created in advance and stored in the storage device 13.

  If the process data collection / accumulation is to be stopped, the process data collection / accumulation is stopped in step 10A04. This is the end of the process in which the monitoring console 1 displays an alarm after receiving the alarm.

  When the monitoring console 1 displays the trend graph 11B based on the process data after receiving the alarm, the process of acquiring process data related to the alarm as shown in <2a> of FIG. 4 and the process shown in <3a> of FIG. The process of displaying process data as such a trend graph 11B is performed. The process of acquiring process data related to an alarm is further divided into a process data acquisition process from feedback control information and a process data acquisition process from sequence control information.

  The feedback control information is information about a process manufacturing apparatus, an input device and an output device of the process manufacturing apparatus, and a device (control target) included in the process manufacturing apparatus. The sequence control information is information about a process step and equipment used for input / output in the step. Feedback control information and sequence control information are created in advance and stored in the storage device 13 as a feedback control information file 13A and a sequence control information file 13B, respectively.

  In this embodiment, by using the feedback control information file 13A and the sequence control information file 13B, not only the process data of the process manufacturing apparatus that generated the alarm, but also the process of another process manufacturing apparatus related to this process manufacturing apparatus. Data can also be displayed on the trend graph.

  The process in which the monitoring console 1 displays a trend graph is demonstrated using FIG. 3B.

  In step 10B01, when the driver who sees the alarm displayed on the display device 11 of the monitoring console 1 selects the alarm display 11A, the display of the trend graph 11B regarding the alarm display 11A is started.

  When displaying the trend graph, in step 10B02, the process manufacturing apparatus and equipment (in the example shown in FIG. 4, the process manufacturing apparatus 3A and the electromagnetic valve 3A3) that generated the alarm are determined from the information in the alarm.

  In step 10B03, process data relating to the process manufacturing apparatus that generated the alarm is acquired from the feedback control information. This process will be described later with reference to FIG. 3C.

  In step 10B04, process data relating to the process manufacturing apparatus that generated the alarm is acquired from the sequence control information. This process will be described later with reference to FIG. 3D.

  In step 10B05, the acquired process data is displayed on the display device 11 as a trend graph 11B.

  In Step 10B06, it is determined whether or not the collection and accumulation of process data has been stopped in Step 10A04 of FIG. 3A. If the process data collection / accumulation has been stopped, the process proceeds to Step 10B07.

  In Step 10B07, it is confirmed whether or not to save the current process data to the operating operator. If the process data is to be saved, the process proceeds to step 10B08.

  In step 10B08, the process data already collected and accumulated in the storage device 13 is saved. The process data is stored in the external storage device 6.

  In step 10B09, as shown in <3b> of FIG. 4, process data collection / accumulation is resumed.

  With reference to FIG. 3C, processing for acquiring process data related to a process manufacturing apparatus that has generated an alarm from feedback control information will be described.

  In step 10B0301, the feedback control information file 13A stored in the storage device 13 is read. As shown in FIG. 4, the feedback control information file 13A manages an input device, an output device, and a control target as feedback control information for each process manufacturing device specified by a device tag.

  In the feedback control information file 13A shown in FIG. 4, the code (3A, 3B, 3C) attached to the process manufacturing apparatus is used as the apparatus tag. The input device described in the feedback control information file 13A represents a process manufacturing device (process manufacturing device used by the process manufacturing device as an input device) to which data is input by the process manufacturing device as a device tag. It is a thing. The output device described in the feedback control information file 13A refers to a process manufacturing device that outputs data from the process manufacturing device (a process manufacturing device that is used as an output device by the process manufacturing device) by an apparatus tag. It is a representation. The input device and the output device are process manufacturing apparatuses related to the process manufacturing apparatus. Some process manufacturing equipment does not have an input device or an output device. The control target described in the feedback control information file 13A represents a device included in the process manufacturing apparatus with a tag. Thus, the feedback control information file 13A describes the process manufacturing apparatus related to each process manufacturing apparatus and the control target of each process manufacturing apparatus.

  In step 10B0302, the feedback control information of the process manufacturing apparatus (3A in the example of FIG. 4) that issued the alarm is read from the feedback control information file 13A.

  In step 10B0303, the control target (3A1, 3A2 in the example of FIG. 4) of the process manufacturing apparatus that generated the alarm is acquired from the read feedback control information, and the process data of the control target is acquired. The process data can be acquired by associating the tags (3A1, 3A2) to be controlled with the tags (3A1, 3A2) recorded in the process data 13C.

  Process data of the process manufacturing apparatus related to the process manufacturing apparatus that has generated the alarm is acquired by the following processing.

  First, in step 10B0304, based on the feedback control information file 13A, it is determined whether the process manufacturing apparatus that has issued the alarm has associated process manufacturing apparatuses (input apparatus and output apparatus). If there is at least one of the input device and the output device, the process proceeds to step 10B0305. In the example of FIG. 4, the input device of the process manufacturing apparatus 3A that generated the alarm is the process manufacturing apparatus 3B, and the output device is the process manufacturing apparatus 3C.

  In step 10B0305, feedback control information of a process manufacturing apparatus (process manufacturing apparatuses 3B and 3C in the example of FIG. 4) used as an input device or an output device is read.

  In step 10B0306, the control target of the process manufacturing apparatus (related process manufacturing apparatus) used as the input device or output device from the read feedback control information (in the example of FIG. 4, 3B1, 3B2, 3C1, 3C2) To obtain the process data of the control target. The process data can be acquired by associating the tag to be controlled with the tag recorded in the process data 13C.

  With reference to FIG. 3D, a process of acquiring process data related to a process manufacturing apparatus that has generated an alarm from sequence control information will be described.

  In step 10B0401, the sequence control information file 13B stored in the storage device 13 is read. The sequence control information file 13B manages a plurality of sequence control information as shown in FIG. In one sequence control information, a plurality of pieces of information including a process step called a step, a device used for input in the step (input device), and a device used for output (output device) are registered. . Depending on the process, an input device or an output device may not be used. The input device and the output device are displayed as tags to be controlled.

  In step 10B0402 and step 10B0403, for the read sequence control information file 13B, input device and output device information (control target tags) is extracted from all steps of all sequence control information, and the extracted input device and output device information is extracted. It is determined whether or not the control target (3A3 in the example of FIG. 4) that generated the alarm is included. That is, it is determined whether or not the control target that generated the alarm matches at least one of the input device and the output device. If it matches at least one of the input device and the output device, the process proceeds to step 10B0404.

  In step 10B0404, the sequence control information step including the matched input device and output device is acquired. Then, process data to be controlled included in this step is acquired. The process data can be acquired by associating the tag to be controlled included in the acquired step with the tag recorded in the process data 13C. In the example of FIG. 4, the input device 3B3 included in step 1 and the output device 3C3 included in step 2 are acquired as control targets included in the step, and the process data of 3B3 and 3C3 are acquired from the process data 13C.

  The process data acquired in this way is displayed on the trend graph 11B as shown by <3a> in FIG.

  As described above, according to the present invention, when the process manufacturing apparatus generates an alarm during operation monitoring, the trend graph of the process manufacturing apparatus that generated the alarm and the process manufacturing apparatus related to the process manufacturing apparatus Since the trend graph can be displayed immediately with a simple operation, the tendency of the process data up to the time of alarm occurrence can be easily grasped. In addition, process data collection / accumulation is stopped in response to the occurrence of an alarm, and process data is saved to an external storage device, and then collection / accumulation is resumed, so that the process data at the time of occurrence of an abnormality can be reliably saved. Can do. Therefore, it is possible to save the situation at the time of occurrence of the abnormality without losing the process data at the time of occurrence of the abnormality.
