Sensor Connection Module for a Patient Monitor
Architecture and firmware development for the connection of additional sensors to an existing patient monitor.
The client needed a new connection module to connect additional sensors via USB to their existing hardware, which was only able to provide an UART interface. The module was supposed to provide the sensor data and allow for sensor configuration via a well-defined and structured protocol. This protocol was also to be defined and developed in the project.
We did the development in a team of mechanic, electronic and firmware developers and provided the module ready for integration to the client. This included automated and manual testing on the unit test and integration test layer of the V-model.
The development was done according to the IEC 62304 standard and the AUTOSAR C++14 guidelines.
Responsibilities
- Responsible for the device firmware in an interdisciplinary, agile team
- Clarification of the software requirements
- Tracing the requirements through to architecture, implementation and tests with Polarion
- Definition and documentation of the software architecture (incl. the interfaces to the electronics)
