example 1

[0078] A first user assigned to a particular area of ​​the plant may monitor the assigned plant area via a stationary workstation within the control room. A first user monitors and controls the process via a browser or other application running on the workstation, which communicates with a routine executing at the server. The first user may determine where to go to the process plant, for example to inspect the plant. When the user leaves the control room, the user can pick up the touch-sensitive tablet device (ie, the second, mobile user interface device) and walk out of the control room to the plant. The tablet, like the workstation, enables the first user to access the routine at the server via a browser or application executing on the tablet. The first user may already be authenticated on the tablet device, or the tablet device may be associated with the first user. The tablet device communicates with the server to establish a session unique to the first user. The server...

example 2

[0086] The first user, still carrying the tablet device, can start walking from the process plant to the control room of the process plant. The first user may pass through the boiler. When the first user walks near the boiler, the tablet device establishes RFID communication with the boiler environment ID device. The tablet device may receive a unique identifier from the context ID device and send the unique identifier to the server. The server can identify the boiler based on the unique identifier. The server may access the context data to determine that the boiler has an associated work item, and compare the skill threshold associated with the work item to the skill level associated with the profile of the first user. Upon determining that the first user is not eligible to work on the work item associated with the boiler, the server may pre-alert the display of the tablet device rather than updating the display with information related to the work item.

[0087] The user ...

example 3

[0089] The first user continues to walk through the factory, still holding the tablet device in hand. A second user located in the control room and now logged into the workstation previously occupied by the first user (or a different workstation) may notice that the critical O2 gas measurement associated with the furnace is dropping. A second user creates a work item requesting assistance with the furnace. When the first user passes the furnace on its way back to the control room, the tablet may automatically establish communication with the furnace environment ID device such that the tablet receives a unique identifier associated with the furnace. The tablet device can send the unique identifier to a server, which can return information associated with the unique identifier (eg, information about the furnace), including a notification graphic that the furnace needs attention. The first user can view and select the notification graphic, causing information related to the crea...

Abstract

A supervisor engine cooperates with an expert system in a process control environment to automatically generate, assign, track, and manage work items. The supervisor engine creates work items according to data received from the expert system, selects available personnel to execute work items, sends work items to the selected personnel, schedules the execution of the work items, and creates and stores permissions that allow the assigned personnel to complete a target function of the work item at an assigned time. The supervisor engine determines required skill sets, roles, certifications, and / or credentials associated with a work item, and selects personnel to perform the work item in accordance with a personnel profile specifying the skill sets, roles, certifications, and / or credentials associated with the personnel. Alternatively or additionally, the supervision engine allocates work items based on personnel appearing in or near target equipment.

Description

[0001] This application is a divisional application, the filing date of the original application is March 14, 2014, the application number is 201410097873.9, and the title of the invention is "supervisory engine for process control. technical field [0002] The present disclosure relates generally to process plants and process control systems, and more particularly to the use of mobile user interface devices in process plants and process control systems. Background technique [0003] Distributed process control systems, such as those used in chemical, petroleum, or other process plants, typically include one or more process controllers connected via an analog, digital, or combined analog / digital bus , or communicatively coupled with one or more field devices via a wireless communication link or network. Field devices, which can be, for example, valves, valve positioners, switches, and transmitters (such as temperature, pressure, level, and flow rate sensors) are located in t...
