Method and control system for controlling and/or monitoring devices

Abstract

A complex control instruction chains in a blockchain for a specific task for controlling devices to be managed in a simple manner is provided, which permit a prescribed validity to be assigned for a specific task of a blockchain-based device control, the validity being defined by the life cycle (e.g. the period of use) of a device, for example.

AI Technical Summary

Benefits of technology

The technology of blockchains is a way to create a secure and trusted database that can record transactions between parties without the need for a middleman. This has applications in the finance industry, where firms can trade with each other without having to establish trust or set up infrastructure. The blockchain is protected by a cryptographic code, known as a smart contract, and can record information like program code or assets. This can help reduce costs and allow for flexible digital services without needing to trust any one party.

Problems solved by technology

A disadvantage in this regard is that a performance of the instruction sequences is difficult to control in a heterogeneous network comprising devices from different operators.

This can be the case e.g. if a fault has occurred on the device during the execution of the control instructions that no longer permits the execution of the control instructions (e.g. a fault occurred on an actuator or tool).

An automated teller machine in Andorra might then not permit a payment or prevent a payment.

In other words, it is in particular not possible to run or jump backwards (that is to say counter to the same common direction) through the transactions or the blocks or the nodes of the graph.

Giving illegal preference to a node (e.g. as a result of fraud / bribery) can be severely hampered if for example a blockchain-based implementation of the distributed database system is used, since protection of confidence or protection against manipulation analogously to Bitcoin is implemented for the control transactions or confirmation transactions.

An automated teller machine in Andorra might then not permit a payment or prevent a payment.

One problem of, by way of example, a large distributed database system, for example implemented as a blockchain, is that data blocks are no longer able to be erased from this distributed database system (a property of blockchains).

This results, in particular, in large volumes of data being stored in the blockchain that are no longer needed, for example.

This is disadvantageous when such architectures are used in the Internet of Things, in particular, since a great deal of energy and storage space is wasted, for example.
