Multiscale noise tuning stochastic resonance (MSTSR) has been proved to be an effective method for enhanced fault diagnosis by taking advantage of noise to detect the incipient faults of the bearings and gearbox. This paper addresses a sequential algorithm for the MSTSR method to detect the train bearing faults in an embedded system through the acoustic signal analysis. Specifically, the energy operator,...
Energy saving is critical to real-time embedded systems. In many embedded systems, some tasks contain conditional instructions or operations that could have different execution times for different inputs. Due to the uncertainties in execution time of these tasks, this paper models each varied execution time as a probabilistic random variable. We propose a practical algorithm to minimize the expected...
RS232 interface executes the role of Transportation and Communication, which has became the important interface between MCU of embedded system and peripheral equipment. Because RS232 mainly work in bottom of communication protocol, so it is important to protect the infrastructure of RS232. In test, pulse double electromagnetic is pulled into RS232 data transmission lines by coupling clamp, simulated...
I2C bus and RS-232 serial port are the important data communication interfaces between the MCU of embedded system and the peripheral equipment. The embedded system performance will be affected under complex electromagnetic environment by the improper disposal to the interfaces, which results in the low speed and reliability. According to the speed matching problems in current embedded programming,...
