Pressure transmitters are widely used in the process industry for pressure measurement. The sensing line, a core component of sensor transmitter, significantly impacts accuracy transmitter’s output. reliability is critical nuclear power industry. Blockage recognized as common failure lines; therefore, novel detection method based on Trend Features Time–Frequency domain characteristics (TFTF) proposed this paper. dataset comprises both fault and normal data. This innovatively integrates...
Industrial control systems(ICS) are widely used in national infrastructure such as electricity, water conservancy and energy to the operation of production equipment. The ICS information security problems will cause a series consequences. This paper focuses on existing industrial communication protocols, studies secure protocols guarantee transmission datas, realizes end-to-end identity authentication data encryption Modbus/TCP protocol.
Fieldbus transmitters are commonly used in modern industrial productions, particularly Safety Instrumented Systems (SIS). and security critical considerations the design operation of these transmitters. Previous research has tended to address safety issues separately, but with increasing complexity network technology, it is important analyze them simultaneously. In this paper, a systematic framework for comprehensively analyzing random failures cyber-attack proposed. The adopts FMEA-IMEA...
Based on the requirements of safety communication in instrumented system (SIS), a fieldbus functional protocol is proposed this paper. According to reasons failure, several measures are used implicitly or explicitly detect error transmission. They include connection authentication, time stamp, sequence number and cyclic redundancy check (CRC). The architecture full structured improve reliability system. Finally, calculation results residual rate show that meets integrity level (SIL) 3.
Electromagnetic coils are indispensable components for energy conversion and transformation in various systems across industries. However, electromagnetic coil insulation failure occurs frequently, which can lead to serious consequences. To facilitate predictive maintenance industrial systems, it is essential monitor degradation prior the formation of turn-to-turn shorts. This paper experimentally investigates from both macro micro perspectives. At level, an evaluation index based on a...
The residual error rate is an essential parameter for evaluating the functional safety of a communication system, based on requirements in instrumented system (SIS). traditional approach quantifying rates incomplete some cases. proposed improvements focus different cases addressing full and partial redundancy models, time expectations verification approaches connection identification. A hypergeometric distribution used when message mode considered.
Based on functional safety standard IEC61508, this paper studies the approaches of pressure transmitter. Following 1oo1D architecture, self-diagnostics measures are used in In order to improve diagnostic coverage, dual CPUs compare results at different calculation stages. The FTA analysis and Markov model for verification. Furthermore, failure fraction (SFF) probability demand (PFD) analysed, indicate that integrity level is SIL2.
