Wearable computer for use in process environment having process control system, in which stored software routine processes input signal and provides process information relating to process control system via head-up display

摘要

The wearable computer provides information pertaining to one or more devices within a process control system e.g. diagnostic information, help information, operator overviews, schematics or process parameter information via a heads-up displays (40). The wearable computer is used in a process control environment and includes a CPU and memory connected to one or more peripheral devices including a heads-up display, a microphone, an imaging device e.g. a video camera and a remote communications device that communicates with the host computer of a process control system. The wearable computer may provide information pertaining to one or more devices within the process control system via the heads up display. The information may include for example, diagnostic information, help, operator overviews, schematics or process parameter information, and may be stored in the memory of the wearable computer or may be obtained from the host via the remote communication device. Independent claims are included for; a device identification unit adapted for use on a wearable computer having a processor and an imaging devices that produces an image signal; a wearable computer for use in testing a process control system; a process control testing unit for use in a process control system.
