The general meeting of the Working Group Machines in Construction MiC 4.0 on 24.01.2020 in Berlin took the topic of standardized machine data of the international standard ISO 15143-3 into the next phase. After the member companies had agreed on a uniform understanding of data in the first step, the focus is now on construction process data. The common goal of the cooperation between manufacturers and users is a quality assurance system to guarantee a uniform standard for the construction industry.
The central concern of the current 80 members is to establish the standards developed by MiC 4.0 in the market and to have them checked by a neutral authority. This requires a test centre for interfaces, conformity audits and certificates as proof. In the coming months, the working group will work out concepts, examine the economic efficiency and search for suitable co-operation partners.
Earth-moving machines, cranes, special civil engineering, road construction, concrete technology, building material plants and attachments are the seven clusters of the Machine Data working group. In different compositions, the participating companies have already agreed on the individual parameters for a uniform understanding of machine condition data. The results for the process data are to be determined in the course of this year.
This will be followed by the work of the Data Rights Working Group. This is a hot topic, as nobody can make a legal claim to data sovereignty. There is no law in e.g. German GTC law that regulates the ownership of general machine data. At the moment, there is only the possibility to make contractual agreements which, for example, categorize the data, assign it to the contracting parties by licensing or create “factual ownership” through encryption and other technical measures.
The System Architecture Working Group deals with the requirements for uni- and bidirectional communication. One cluster deals with the system architecture IN the machine – subject area machine/attachment telemetry unit, another cluster deals with the system architecture UM the machine – subject area server to server.
Standards for the structures, processes and symbols for operating mobile machines are defined by the Human Machine Interface HMI working group. Manufacturers, machine users and system integrators are continuously working on a coordinated industrial standard. This will be followed by a standardization process.
The research project Building 4.0, funded by the Federal Ministry of Education and Research, is a joint project of 20 industrial partners and two universities – the Institute for Mechatronic Mechanical Engineering at the TU Dresden is the overall leader. Both universities presented the current state of research. They are working on the topics of automation and networking of working machines, 5G machine and construction site networking and solutions for digital processes on the construction site. The vision is to develop a completely digitalized, automated and flexibly adaptable construction site, with possibilities to simulate and optimize construction machinery and construction processes, to involve the operators as coordinators to increase efficiency and productivity and thus create new business models and value chains. The project will run until 31.07.2022 with a total cost of € 9 million, of which € 4.8 million is funded.
