2022-August | plc-tec’s research partner HSLU has finalized the research project reg. the utilisation of the PLUS signal to detect power line wire faults. The results are promising and will be published soon in an aircraft journal.  

The developed method has also the potential to monitor the health of pin contacts in the e-coupler of the Digital Automatic Coupler DAC and could be integrated into PLUS PTB. Therefore, an innovation project has been started with SBB Cargo with the goal of a Health Monitoring System for the DAC e-coupler which would allow predictive maintenance. The project is supported by the Swiss innovation agency Innosuisse.

2022-March | plc-tec, HSLU and SBB Cargo have started a joint project for the testing of the of Digital Automatic Coupler DAC with the PLUS PTB as train backbone for automated train functions like train inauguration, automatic brake test, train integrity monitoring, etc. The focus is on the reliability of the DAC in the tough operational processes e.g., during coupling where the wagons collide at up to 12 km/h, with harsh environmental conditions, etc. Reliability is seen as a major challenge for the acceptance of the DAC. A test train (DAC+ Train Fully automated. Now.) is assembled with several different measuring devices; stand-still and drive tests will be performed. Further project partners are VOITH and PJM. The project is co-funded by the Swiss Federal Office of Transport.

2022-February | plc-tec has finalized the development of the PLUS-V2 Product Platform. A number of modems are currently in lab tests and will then be tested in the field.  

2021-December |  plc-tec’s research partner HSLU / CC ISN and maxon have finalized successfully an innovation project for a health monitoring system of electrical drives in an aircraft. The health of the motors is monitored by appropriate sensors whose raw data is processed locally in a distributed embedded system. The resulting data is then streamed with PLUS via the power supply cabling to further processing in other parts of the aircraft. A demonstrator has been developed for the ventilation control system of passenger aircrafts where several electric drives are typically installed. The project has been co-funded by Innosuisse, the Swiss innovation agency and was supported also by Diehl Aerospace and Collins.

2021-October |  Successful demonstration of PLUS PTB at the VOITH live event on October 19 on the premises of the Havelländische Eisenbahn (HVLE): VOITH presented their current status of automation and digitalisation to international representatives of the railways in Europe.

The focus was on live demonstrations of the technologies on the train including the world premiere of remote uncoupling. Coupling and uncoupling were demonstrated, including PTB data transmission and the rapid disassembly and assembly of the coupler head for easy maintenance.
