Remote Workplace Monitoring With Local Gas Alarm Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems for workplaces are inefficient in remotely detecting hazardous gases and events, often requiring complex setups and risking delays or false alarms due to outdated decision rules and extensive data transmission.
Innovation Solution
A monitoring system comprising cameras, gas detectors, and workplace computers, with localized processing and wireless communication, allows for remote monitoring by transmitting alarms directly to a control center, reducing data traffic and enabling real-time visual and acoustic alerts, while minimizing equipment exposure to hazardous conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If monitoring systems transmit all measured data to a central location, then complete information is available for analysis, but data transmission time and network bandwidth are excessively consumed
Solution Approach 1:
The monitoring system segments data processing between local evaluation units at each workplace and a central server. Local units evaluate measured values against decision rules and only transmit alarm notifications when thresholds are exceeded, rather than continuously transmitting all raw data. This segmentation reduces network bandwidth consumption and transmission time while preserving critical information about hazardous conditions.
2Adaptability or versatility
If monitoring systems use centralized decision rules stored at a central location, then decision logic can be updated centrally, but transmission of measured values to the central location increases data traffic and response time
Solution Approach 1:
Decision rules are pre-loaded into local evaluation units during system initialization or maintenance periods. The local units store and execute these rules autonomously during operation, eliminating the need for continuous data transmission to a central location for evaluation. This preliminary action reduces operational data traffic while maintaining the ability to update rules between operations.
3Speed
If monitoring equipment is placed directly in hazardous workplaces, then real-time detection is achieved, but equipment exposure to harmful gases increases reliability risks
Solution Approach 1:
The system introduces wireless communication as an intermediary between the monitoring equipment and the central server. Monitoring units can be positioned in hazardous areas to detect gases in real-time, but they transmit data wirelessly to a safe central location for evaluation and storage. This intermediary communication method allows the monitoring equipment to remain exposed briefly for detection while the critical evaluation and data storage occur in safe, protected environments, thereby maintaining both detection speed and equipment reliability.

AI summary
A system and a process enable a workplace (A.1, A.2) to be monitored remotely. A monitoring unit for the workplace includes a camera (2.1, 2.2, 2.3), a gas measuring device (1.1, 1.2, 1.3, 1.4) and a workplace computer (3.1, 3.2). A communication unit (10) communicates with a control center with a central output computer and an output unit. Signals from the camera and the gas measuring device are transmitted by cable or wirelessly to the workplace computer and from there further transmitted by cable or wirelessly to the communication unit. The signals are transmitted wirelessly from the communication unit to the central output computer. The central output computer causes the received signals to be output on the output unit in a form that can be perceived by a human. The data connection between the communication unit and the central output computer may be routed via a public mobile radio network.
