Ensuring the safety of human workers collaborating with industrial robots is paramount. This research work presents a novel approach by developing a safety-related intruder detection system for the operational zones of industrial robots, following the IEC 61508 standard and adopting the related redundant architecture. The hardware integrates light curtains and radar sensors in a dual-layer configuration, while the software utilizes a safety system-on-chip to implement real-time diagnostics and fault tolerance. Protecting employees and ensuring a smooth and safe work environment are significant concerns for all companies. As a result, numerous standards and regulations have been established to provide safe collaboration between humans and machines. However, despite these measures, accidents continue to occur, resulting in varying degrees of injuries. The proposed system is depicted through a comprehensive schematic, emphasizing the integration of safety measures within the robotic environment. The detailed prototype demonstrates practical application, show-casing the system's ability to detect intrusions, initiate emergency responses, and transition to fail-safe states during component failures. This research work advances safety protocols in human-robot collaboration within industrial settings, fostering a safe working environment through a well-defined safety framework. © 2025 IEEE.

The use of complex electronic systems in medical technology applications is constantly increasing. These systems are becoming increasingly important, particularly in the area of analyzing the progress of treatment, as they can be used to identify any deficits that may still exist. Although systems are now available from a number of manufacturers, they are not always applicable to all mobile problems, so approaches with adapted system technology must be used. © 2025 IEEE.

A theoretical approach to a safety-based predictive adaptation of wireless communication channel parameters in harsh environments

Safety in Extreme Environments 2020年第1期2卷 93-101页

作者： Gaus, L. Schwarz, M. Boercsoek, J. Computer Architecture and System Programming University of Kassel Kassel Germany

This paper presents an approach to a real-time optimization of safety parameters in wireless communication systems. When considering the GEC–model (Generalized Erasure Channel) and the black channel design of a communication channel, then the PFH (Probability of Failure per Hour) value can be estimated using the parameters ε – BER (bit-error-rate), φ – BLR (bit-loss-rate), v – number of safety related messages per second, n – message length and d_min – minimum distance of a linear code. The number of safety related messages per second v and the message length n, including the information block k and the checksum block r, can be varying between the permissible bounds. Accordingly, the variable parameters can be adjusted at run-time with additional assimilation of the used cyclic code. It allows the real-time prediction and optimization of the safety parameters. In this paper, the concept of the parameter estimation is discussed and based on it the optimization problem is defined. © Springer Nature Switzerland AG 2020.

Concepts of safety networks in industries

This paper details the needs, demands and specifications to be incorporated and satisfied to design safety bus systems for modern industries. Distributed control systems in industries are connected via bus systems, and need efficient and uninterrupted communication between all bus stations. Therefore, it is compulsory that these communications are fault tolerant and safe. For safety related systems, further safety layers are mandatory to perform these requirements. In a safety related application it is important that the safe protocol alone is not able to achieve this task without a safety source node at one end and a safe destination node at the other. Only the combination between safety related protocol and safety related hardware nodes can accomplish the requirements for safety related networks systems.

7th International Conference on Electrical and Electronics Engineering, ELECO 2011

This particular essay expounds upon how one can foresee and predict software reliability. There are two major components that exist within a computer system: hardware and software. The reliabilities between the two are comparable because both are stochastic processes, which can be described by probability distributions. With this said, software reliability is the probability that will function without failure in a given software and in a given environment during a specified period of time. Thus, this is why software reliability is a major and key factor in software developmental processes and quality. However, one can spot the difference between software reliability and hardware reliability where it concerns the quality duration and the fact that software reliability does not decrease its reliability over time. © 2011 Chamber of Turkish Electric.

Safety-related systems mostly comprise hardware and software solutions. Due to the increasing application of complex hardware and software systems, the software systems have to be considered regarding safety as well as hardware systems. The development of a safety-related software system is similar to the development of a safety-related hardware systems. But there are still no generally accepted methods for developing safety-critical software. One has to use the methods, which fit best to the actual requirements. However, the calculation of reliability and availability for safety-related software systems is far more complex. © 2007 IEEE.

In this paper, the optimization of safety parameters for a communication channel with the required safety integrity level (SIL) 3 at runtime is investigated. In order to guarantee the safe communication additional measures are needed. One of them is the black channel principle. It allows the transfer of safety related packets over the safety layer parallel to safety irrelevant data. Another method is the protection by a linear code, typically by cyclic redundancy check (CRC). In terms of the safety level, the information channel can be assumed as a generalized erasure channel (GEC) with the set of output symbols (0, e, 1). For this channel a formula for probability of failure per hour (PFH) can be derived using the parameters: bit error ratio, bit loss rate, message rate, code block length and weight spectrum. Within the safety layer, the communication occurs in the send-/receive-response principle (cyclic mode) and the messages can have a length defined by bounds on nmin and nmax. Accordingly, the optimization problem is formulated to minimize the PFH value by optimizing the message length for changing parameter values. © 2019 European Safety and Reliability Association.

Enhancing a simulation environment for computer architecture to a systemC based testbench tool for design verification

2011 23rd International Symposium on Information, Communication and Automation Technologies, ICAT 2011

This paper presents a simulation environment, which is a C++/systemC based integrated framework for functional verification of designed components or electronic architectures and enhances the existing computer architecture simulation tool named sefca. As the VHDL sources are converted to systemC it is sufficient for verification engineers to have a fundamental knowledge of C++ and the systemC library. The testbench framework uses the same graphical user interface (GUI) based on the wxPython library, which was presented in the sefca tool. Verification of the design is supported by the systemC verification library (SCV). Inter-Process-Communication is used to send the stimuli for simulation input from the GUI to the simulation process and the simulation results back to the online viewer in the GUI. With these enhancements sefca becomes a universal tool for testing the software and the hardware part of a new design at the same time. Working on the transaction level model (TLM) the proposed methodology offers a high performance and a high level of abstraction. © 2011 IEEE.
