Innovation Solution
A condition monitoring system that includes a network of distributed devices with a monitoring unit and a portable communication device, where the monitoring unit automatically updates the portable device with current condition data, using a wireless or wire-bound communication interface, and employs a computer-readable code for secure access, ensuring accurate data exchange and storage with a central control server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service workers manually manage maintenance schedules and data collection, then flexibility in performing maintenance tasks is maintained, but data accuracy deteriorates due to human errors such as mixing up turbine identification numbers and storing data under wrong identifiers
Solution Approach 1:
The monitoring unit automatically performs data collection, processing, and transmission without human intervention. The system self-identifies the device using embedded identification data, eliminating the need for service workers to manually input or match turbine identification numbers, thus preventing data mix-ups while maintaining system simplicity
Solution Approach 2:
Manual data management processes are replaced by an automated electronic system. The monitoring unit uses communication interfaces (wireless or wire-bound) to automatically transmit processed condition data with device identification to the central control server, replacing the mechanical process of manual data entry and storage
2Reliability
If service workers are provided with maintenance schedules in advance, then preparation time is improved, but information currency deteriorates because schedules become outdated and incomplete when reached at the turbine hours or days later
Solution Approach 1:
The monitoring unit continuously collects and processes condition data in advance, preparing updated information before the service worker arrives. When the portable communication device connects to the monitoring unit, the service worker immediately receives the most current condition data and service information, ensuring information currency without requiring advance scheduling
Solution Approach 2:
The system establishes a feedback loop where condition data is continuously monitored and automatically transmitted to portable devices. This real-time feedback ensures that service workers always access current information about device status, maintenance needs, and operational conditions, eliminating outdated schedules
3Reliability
If fixed wire-bound communication links are used between monitoring units and central control servers, then communication reliability is improved, but accessibility deteriorates in off-shore locations where cable guidance is difficult and maintenance is costly
Solution Approach 1:
The portable communication device acts as an intermediary between the monitoring unit and the service worker. It receives condition data from the monitoring unit via wireless communication and provides access to service information without requiring direct physical connection or cable guidance to the central control server, simplifying off-shore installation and maintenance
Solution Approach 2:
The fixed wire-bound communication link is replaced with wireless communication interfaces (such as radio frequency communication). This substitution eliminates the need for physical cable guidance through challenging off-shore environments while maintaining communication functionality between monitoring units and portable devices
4Reliability
If satellite communication is used in off-shore wind energy parks, then communication availability is improved, but cost deteriorates significantly
Solution Approach 1:
Instead of using expensive satellite communication for all data transmission, the system uses partial wireless communication locally between the monitoring unit and portable device. This partial action approach provides sufficient communication availability for maintenance operations without incurring the high costs of satellite communication for every data exchange
