In this paper an the envelope extension method based on grey prediction is proposed to restrain the end effects of empirical mode decomposition (EMD). The extended signal can reflect trend of raw signal envelope amplitudes, this extension method is simple and ideal. Based on improvement of the empirical mode decomposition, EMD decomposition is used to(More)
According to the needs of the security operation taxi, a kind of vehicle monitoring terminal device which takes C8051F040 microcontroller as the core, combining GPS, GPRS and LCD was proposed. This device will show the superiority of C8051F040 microcontroller, which is high-speed, low-power, and has rich interface. Through the application of GPS, LCD, and(More)
As a population-based optimizer, the differential evolution (DE) algorithm has a very good reputation for its competence in global search and numerical robustness. DE retains the knowledge of good solutions in the current population. To achieving a desirable tradeoff between exploration and exploitation, a new adaptive differential evolution is introduced(More)

This paper introduced the designing method and working principle of a high precision pressure data acquisition system, which use MSC1210 mcu chip as data acquisition processing center. This system used pressure sensors to collect signals and used multiplexer to switch signals. After PGA signal amplification, S-¦¤ modulation, digital filtering,(More)
