Interactive two-way collaboration in process control plants

Abstract

Systems and methods of transmitting process control information to a portable communication device associate a resource link with the process control information and transmit the process control information and the resource link to the portable communication device. A session identifier is associated with the process control information and the session identifier and the resource link are transmitted to the portable communication device. A message and the resource link associated with the process control information are provided at the portable communication device. A user selects the resource link to initiate a communication link between the portable communication device and a wireless communication service. The portable communication device may receive one of video information, audio information, still image information, and software application information in response to initiation of the communication link between the wireless communication service and the portable communication device.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of November 21, 2003, an application number of 200310116440.5, and an invention title of "Interactive Two-Way Cooperation in a Process Control Factory". technical field [0002] The present invention relates generally to a process control system, and more particularly, the present invention relates to interactive two-way cooperation in a process control plant. Background technique [0003] Process control systems, such as those used in chemical, petroleum, or other processes, typically include communicatively coupling to at least one host or operator workstation via an analog, digital, or combined analog / digital bus, or to a One or more centralized process controllers for one or more field devices. Field devices, such as valves, valve positioners, switches, and transmitters such as temperature, pressure, and flow rate sensors, perform in-process functions such as opening...

What's more, for existing two-way calling systems, the responses sent by portable communication devices (such as pagers, cell phones, etc.) are usually limited to simple text messages and / or simple numerical values, thus significantly limiting the number of people who can respond to alarms or alerts. Ability to make appropriate corrections from a remote location
