Abstract [en]

The report describes the project carried out for EasyServ, whose business is based on the monitoring and diagnosis of heat pumps. Their desire for the project was to develop a more efficient test system that makes it possible to easily simulate a heat pump behavior. The purpose of this was to enable more efficient tests with better accuracy for EasyServs product. This simplifies the quality assurance of the software for their product.

The main problems the project were facing was how the test system should be designed and how the simulation of the heat pump's temperature sensors would be to mimic a heat pump. Another question mark was which communication interface was best suited for the test system.

The method for constructing the test system was based on the use of the simulation technology Hardware-in-the-loop (HIL). The project was thus divided into subsystems Electronics Design and Programming. In Electronic design the decisions regarding the design were taken and the construction of the test system was made. The Programming subsystem deals with the development of the simulation program.

The result was a test system consisting of a Raspberry Pi and a manufactured I/O board, where communication takes place through I²C. The I/O board has eight digital potentiometers which are used to simulate the heat pump’s temperature sensors. The simulation program developed in Raspberry Pi uses Python as programming language.

The conclusion is that the project's test system provides a good basis for EasyServ to test their diagnostic tool in a simple way. A potential and desirable development that makes the test system even more useful for EasyServ would be to feedback the compressor signal.
