Aiming at the problem that the existing pneumatic brake of mobile bridge erecting machine could not realize heavy load downhill, a new type of balance circuit which could be used in closed drive system with variable load was designed, and was applied to electro-hydraulic proportional braking system. The working principle of the closed drive system was analyzed, and the static characteristics of the overload phenomenon were analyzed. The simulation model of the braking system was established by AMESim software, and the dynamic characteristics of the system were analyzed. The results show that when the motor turns downhill, the pressure difference between the inlet and outlet of the motor decreases by 87. 6%? and the speed increases by 52. 4%. The motor has a large speed impact, the pressure difference and speed of the motor at the inlet and outlet decrease and rise respectively under the downhill condition, when the load is exceeded, by increasing, the pressure of the proportional relief valve braking requirements of bridge erecting machine, the pressure difference and speed at the inlet and outlet of the motor can be stabilized and the flow can be satisfied.

To improve the teaching effectiveness of speech signal processing course and solve the problems on experiment of speech signal processing under the real-time environment, the experimental scheme is discussed and the embedded experimental platform based on ARM Cortex-AS is designed with the support of advanced Linux sound architecture ( ALSA). The experiments of speech analysis, enhancement, feature extraction are implemented. The comprehensive project based on real-time speech signal processing can train students to improve their professional competence and engineering capability. Taking the speech emotion recognition as an example, the hardware design, the software framework and the algorithms are introduced and implemented in this paper. [ABSTRACT FROM AUTHOR]

To embody the idea of mutual promotion between teaching and scientific research, and to meet the needs of teaching and research for speech signal processing, an integrated experimental platform for embedded speech signal processing is design by using Cortex-A8 microprocessor and WM8960 audio coding and decoding chip as core hardware. Moreover, an integrated experimental teaching and development software is designed on this platform by using QT development software. Then, the system hardware structure and transplant of driver are described. By taking an example of the speech enhancement algorithm based on spectral subtraction, the speech development process based on QT is introduced. Based on this experimental platform, students can master not only the basic knowledge of speech signal processing, but also the development process of embedded software for the speech application. The system had friendly interface and strong functions, can be used for the teaching of speech and signal processing in colleges and universities, and for the research and development of related topics on speech signal processing.
