Description

  The present invention relates to an alert notification system and an alert notification device for notifying an alert issued by a control system and a device management device and an alert in a device to be controlled such as a field device.

  For example, a control system is used for monitoring control of each facility or plant attached to a building, and an equipment management device may be used (see Patent Document 1). For example, a device management device exchanges signals with field devices such as process devices and various sensors installed on the site connected via a network such as a field bus, and conventionally a portable terminal has been installed on the field device. It is possible to perform calibration that is directly connected to the device by setting parameters from the host, and display a diagnosis result regarding a state in which the field device is operating normally, for example, issuing an alarm or the like.

  In such a control, since a large number of field devices are controlled, in the control system, a controller that divides the data into blocks and controls each block is arranged, and distributed control is performed using a plurality of controllers. I have to.

  For example, as shown in FIG. 3, a controller 202 provided for each block is connected to the control station 201, and a plurality of I / O modules 203 are connected to each of the plurality of controllers 202. A plurality of field devices 204 are connected to the O module 203. A plurality of controllers 202 are connected to the control station 201 via a network 211, and a plurality of field devices 204 are connected to each I / O module 203 through a signal line 212.

  The controller 202 has I / O data points to which individual inputs from the field devices 204 such as sensors and opening outputs from the field devices 204 such as valve positioners are individually connected via the I / O module 203. I have.

  In such a control system, there is a case where the field device is replaced and the field device is set at the site where the field device is installed for maintenance such as failure, periodic replacement, and periodic inspection. In such a case, a portable setting device is used (see Patent Document 2).

FIG. 1 is a configuration diagram showing a configuration of an alert notification system according to an embodiment of the present invention. FIG. 2 is an explanatory diagram illustrating a display example of the display unit 126. FIG. 3 is a configuration diagram showing a configuration of a control system that divides the block into blocks and controls each block.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of an alert notification system according to an embodiment of the present invention. This system includes an alert notification device 101, a setting device 120, and a field device (control target device) 131.

  The alert notification device 101 includes a control connection data storage unit 102, a definition data storage unit 103, a corresponding data generation unit 104, a corresponding data storage unit 105, and an alert transmission unit 106. The setting device 120 is connected to the field device 131 and sets the field device 131. The setting device 120 includes an alert reception unit 121, a target device information storage unit 122, a setting control unit 123, an input unit 124, an alert confirmation unit 125, and a display unit 126. The setting device 120 is accommodated in a network 151 to which the alert notification device 101 is connected. The network 151 is, for example, a wireless local area network (LAN), and is different from a network in which the field device 131 is connected to a control system or a device management apparatus.

  The control connection data storage unit 102 stores control connection data indicating a connection state including an item of control tag information for identifying a field device 131 connected to a control system (not shown) in the control system. For example, the control connection data illustrated in the following Table 1 used in the control system is stored in the control connection data storage unit 102.

  The definition data storage unit 103 stores definition data for defining the field device 131 including an item of device tag information for identifying the field device 131 in the device management apparatus (not shown). For example, definition data exemplified in Table 2 below used in the device management apparatus is stored in the definition data storage unit 103.

  The correspondence data generation unit 104 combines the control connection data stored in the control connection data storage unit 102 and the definition data stored in the definition data storage unit 103, and uses the device tag information as the control tag information of the field device 131. Corresponding data is generated by combining. For example, the correspondence data generation unit 104 generates the correspondence data illustrated in Table 3 below. The generated correspondence data is stored in the correspondence data storage unit 105.

  The alert sending unit 106 generates an alert identified by the control tag information generated in response to the abnormality occurring in the field device 131 detected by the control system, and the corresponding data generation unit 104 generates and stores the alert in the corresponding data generation unit 104. The corresponding data is sent to the network 151 together with the device tag information combined with the control tag. When the occurrence of an alert is detected at an AI point in the control loop 0230002 specified by the control tag “FI002”, the alert sending unit 106 refers to the corresponding data described above and is included in the control loop “FI002” and the control loop 0230002. Along with the device tag “U02FI002” combined with the control tag FI002 and the device ID “00360a01002”, alert information indicating that an abnormality has occurred is sent to the network 151.

  Alerts indicate control-related abnormalities (process alerts), such as states that exceed the upper and lower limits set as control values and setpoint thresholds, and values that change too quickly. There is a device alert that indicates an abnormality due to a self-diagnosis result detected by the field device 131 itself or a device state diagnosis result detected by the device management apparatus.

  The alert reception unit 121 receives alert information sent to the network 151 as described above. The target device information storage unit 122 stores device tag information and device ID of the field device 131 connected to the setting device 120 for setting.

  For example, the setting control unit 123 changes the setting of the connected field device 131 according to a setting change instruction received from the input unit 124. The setting control unit 123 reads out the device tag and the device ID from the connected field device 131 and stores them in the target device information storage unit 122.

  The alert confirmation unit 125 compares the device tag and device ID included in the alert information received by the alert receiving unit 121 with the device tag and device ID stored in the target device information storage unit 122. Moreover, the alert confirmation part 125 displays the received alert information on the display part 126, when the said comparison corresponds. Here, when at least one of the device tag and the device ID matches, the received alert information is displayed on the display unit 126.

  As described above, the setting device 120 displays the received alert on the display unit 126 as illustrated in FIG. 2 by receiving the alert information including the device tag information for identifying the setting target field device 131. As a result, an alert regarding a control loop including the field device 131 is immediately notified to the operator who is operating the setting device 120 during work such as setting change for the field device 131 in the field.

  As a result, for example, the occurrence of an alarm such as a process alert or a device alert that may occur due to a new setting for the field device 131 can be immediately confirmed. In addition, this alert is not notified after being confirmed by the operator monitored by the control system or the field engineer monitored by the device management apparatus, even if the operator or the field engineer overlooks this alert. The operator can confirm.

  By the way, in the correspondence data storage unit 105, control tag information for identifying an input point or an output point that is a connection destination of the field device 131 used in the control system to which the field device 131 is connected, and a control loop and the control tag information are identified. Corresponding data may be stored that combines control loop configuration tag information that holds information on the function blocks to be configured together with device tag information that identifies the field device 131 in the device management apparatus. In this case, the alert sending unit 106, together with the device tag information combined with the control tag in the correspondence data stored in the correspondence data storage unit 105, the alert generated in response to the abnormality detected by the control system in the functional block. Send to network 151

  The alert confirmation unit 125, if any of the device tag and the device ID included in the alert information received by the alert receiving unit 121 matches the device tag or the device ID stored in the target device information storage unit 122. The received alert information is displayed on the display unit 126. Therefore, even when no alert is generated in the currently set field device, an alert generated in another field device in the same control loop due to the setting change can be confirmed.

  Further, alerts relating to predefined field devices may always be displayed and excluded from display targets. Accordingly, it is possible to cope with a case where it is desired to always display an alert regarding a field device important for control or the like, but not to display an alert for a field device that is known to be under maintenance. In addition, maintenance information related to the notified device tag or device ID may be transmitted together with an alert.

  In the setting device, the operation record is saved, and the setting to the field device can be restored. In this way, immediately after confirming the alert, it is possible to easily and reliably return the setting that created the alert occurrence state. In addition, setting information for setting the operation of the target field device in a safer direction may be prepared in the setting device, and after confirming the alert, the setting information may be reflected.

  As described above, according to the present invention, the correspondence data is generated by combining the device tag information with the control tag information of the control loop to which the control target device belongs, and the alert identified by the control tag information is generated. Since the corresponding data generated by the department is sent to the network together with the device tag information combined with the device tag belonging to the same control loop, oversight of alarms can be prevented while reducing the burden on personnel. .

  The present invention is not limited to the embodiment described above, and many modifications and combinations can be implemented by those having ordinary knowledge in the art within the technical idea of the present invention. It is obvious. For example, the network 151 is not limited to a wireless LAN, and may be a wired LAN provided at a site where the field device 131 is installed. Further, determination and detection of process alerts and device alerts may be performed anywhere in the control system or device management apparatus.
