Design principles of Human Machine Interface Systems In Industrial automation
The human-machine interface systems, including the development of Robotic systems and safety Controls need high level and detailed design Process. It has remarkable correlation with quality management and Industrial Automation Processes. Safty through Design Process is similar to TQM, ISO 9000 processes. By adopting these high level priniciples, establishing objectives, and starting at the design stage, the safety of workers and products can be impacted.
What Should Be Automated?
First, Identify types of automation by information acquisition, information analysis, decision & action selection, and action implementation. After this, Identify levels of automation by applying primary evaluation criteria, human performance consequences, mental workload, skill degradation. After arriving initial type and level, apply secondary evaluation criteria through reliablity and costs of action outcomes.
The Basic Design Priniciples of Industial Robotics
The first and most important engineeing design priniciple is, the automated system must be predictable and there must be a way to monitor the system. Training, learning and operation of automated system should be simple. The human operator must be informed, involved and he must be in command. Also, only automate new functionalities if there is a need.
Preliminary Design
The preliminary design phase of saftey Industrial Automation has the following three important aspects
- Needs and Task Analysis
- Great Ideas, Story Boards and Demonstrations
- End user and industry based prototype design standards
Detailed Design
Here design tradeoff and workflow analysis plays a crucial role. At this point, documentation and industry user manual for the detailed design should be prepared. The document should have information about usablity evalution of prototypes and performance and effectiveness criteria of the detailed design.
- Basic Design Elements : Durability, proper function allocation,user testing,reliability
- Simplicity
- Consistency : Be consistant with user mental model
- Standardization : Maintain identical interfaces for identical functions
- Safety : Provide a fail-safe design and make it error tolerant
- User-centered perspective : Maximize human performance but minimize training requirements
- Support
- Maintenance
