Volvo CE. Real time data streaming and stream storage The test bed has two options depending on possibility to get live data streams available over the Internet. Option 1 includes the use of live data streams and simulated data streams, whereas option 2 includes only simulated data streams. The test bed should comprise many data streams and within those one or more data streams should contain anomalies etc. that should be detected. If option 1 is possible, the excavator in the pilot set-up at Volvo CE will be used and run in provoked modes as well as for instance low maintenance conditions can be induced to produce sensor values that should be detected. Furthermore Volvo CE will equip two of their wheel loaders with all requested sensors and transmission capabilities to transfer the generated data stream. Even signals that are only giver by internal operations on the CAN bus or in the motor control unit will be made available but under specific confidentiality requirements.
Volvo CE. Volvo CE has a vision where the construction machinery in operation at customer sites are monitored in more detail than today, giving the possibility to perform improved support for product planning, design, customer support agreement validation, maintenance prediction, data driven fault detection, automated fault diagnosis calibration, interactive remote fault diagnosis and optimization of site logistics and operator driving behavior. Commonly to all use cases that have been identified at Volvo is the global distribution of locations where their construction machine fleets are used. Connecting places with low mobile phone and satellite coverage represents an impressive high cost factor to transfer the data streams. This necessitates an analysis of how much computing power and storage should be assigned for the machines and how this should be traded towards the communication cost and availability of communication means. Volvo CE will work on a global view of this problem to address how markets such as the African continent shall be dealt with. At the African continent Volvo CE will develop low costs solutions and have low or infrequent access to the machines. This is a lot harder in comparison to markets where more expensive machines are used and where there is better access and lower communication costs to send large amounts of data. Especially use cases that take this situation in account create a challenge for the consortium and help to generate solutions that can be applied in similar difficult scenarios.
Volvo CE. From a Volvo CE perspective, the stakeholders are: the operator utilizing the Volvo CE machine, the site owner, the machine owner, the dealer or other third party that provides services to the end customer, Volvo CE back office users and development partners. The operator would in the machine have access to a set of data streams where the available data streams is given by a table stored onboard the machine linking operator ID to stream ID. Example of streams could be loaded tons/consumed fuel in liters, cycle time. The machine owner and site owner would have access by wireless communication to most streams of the operator but would also have access to information on total cost of ownership, on accumulated loaded tons per material type, operator efficiency in tons/hour, machine uptime and comparison of operator to operators having same type of machine and applications at other Volvo CE customers and more. The access rights for the machine and site owner are stored at the Volvo CE back office. The dealers and third party service vendors have access to machine deviation detection streams in order to trigger these service providers to take a closer look at the machine in question. They also receive error codes. They receive the data streams from servers run by the site owners. Volvo CE has complete access to the data streams available from servers run by the site owners. This includes on top of previously mentioned machine usage characterization in terms of types of operations performed and component usage in 1D and 2D histograms displaying e.g. time spent at a certain speed/torque range or the amount of times a certain gear shift has occurred. The Volvo CE development partners have access to data streams through Volvo CE and can have restricted access to selected machine usage streams to evaluate the usage of their supplied machine components. The external service providers can have the same setup to evaluate their services. The roles Volvo CE is interested in are: operator, machine owner, site owner, service provider, back office, development partner.
