Transmitter Display Sharing for Nearby Measurement Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In process instrument measurement, transmitters without display screens or buttons, such as temperature transmitters, require operators to access distant device managers for maintenance information, making it inconvenient and time-consuming to understand their operating conditions or perform repairs.
Innovation Solution
A method and system that allows measurement information from a second transmitter to be displayed on the display screen of a first transmitter via a pre-configured data transmission path, enabling operators to access this information conveniently and timely, even when the second transmitter is far away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transmitters are placed far from the device manager for process monitoring, then the coverage area is improved, but the ease of operation deteriorates because operators cannot conveniently access measurement information
Solution Approach 1:
The patent introduces a portable device as an intermediary between the transmitter and the device manager. This portable device receives measurement information from the transmitter via wireless communication and displays it locally, serving as a mediator that brings the device manager's functionality to locations near the transmitter without requiring physical proximity to the actual device manager
Solution Approach 2:
The portable device creates a copy of the measurement information display functionality. Instead of requiring operators to access the original device manager interface, the system generates and displays a replicated version of the measurement information on the portable device's screen, enabling remote viewing without modifying the original system architecture
2Device complexity
If transmitters without display screens are used for specific process measurements, then the device complexity is reduced, but the ease of operation deteriorates because operators cannot view measurement information directly at the transmitter location
Solution Approach 1:
The display functionality is extracted from the transmitter itself and relocated to a separate portable device. The transmitter maintains its simple design without a display screen, while the portable device assumes the responsibility of displaying measurement information, separating the measurement function from the display function
Solution Approach 2:
The portable device serves multiple functions: it acts as a display device for transmitters without screens, provides a portable access point to the device manager, and enables remote monitoring capability. This multi-functional approach allows a single device to address multiple operational needs
3Extent of automation
If operators access measurement information through a distant device manager, then centralized control is maintained, but the loss of time increases due to the distance and inconvenience of accessing information
Solution Approach 1:
The portable device performs preliminary actions by caching and displaying measurement information locally before operators need to access the device manager. The system proactively retrieves and displays measurement data on the portable device, so when operators need information, it is already available without requiring a trip to the device manager
Data Source
AI summary
A method, apparatus and system are for displaying measurement information. An embodiment of the method includes: obtaining a display instruction for displaying measurement information of at least one second transmitter; and displaying, after obtaining the display instruction, the measurement information of the at least one second transmitter on a display screen of the a first transmitter. The first transmitter and the at least one second transmitter perform data communication with a distributed I/O device according to a preconfigured data transmission path. Further, the measurement information of the at least one second transmitter is obtained by means of the distributed I/O device according to the preconfigured data transmission path. The embodiment of the method enables an operator to conveniently view the measurement information of the second transmitter on the first transmitter nearby, without viewing the information on a remote device manager or the second transmitter.
