Not only eco-friendly energy sources such as secondary fuel cells and hydrogen fuel cells, but also digital technological innovations based on artificial intelligences are keen technological developments in Construction Equipment nowadays. In parallel to increasing application of intelligent, automated, and unmanned Construction Equipment for functional safety, AI regulation for Safety Related Parts of Control System (SRP/CS) has been reinforced in Europe, such as Machinery Regulation (EU) 2023/1230.
In this paper, we will briefly review functional safety design principles, system Failure Mode Effect Analysis, hardware failure rate estimation, and a way to reduce residual risks in controllers for Construction Equipment based on ISO 13849. Instead of actual controllers used in the field, a virtual controller with multiple inputs and outputs is considered. A virtual bill of materials (BOM) consisted of passive elements and active elements will be listed for our discussions. Based on these databases, we will estimate hardware failure rate, define safety goal and safety states, functional specification requirement (FSR), and safety based on System FEMA for this virtual controller.
