To get over the problem that only one type of filter cannot meet the requests of field monitoring, a rotating machine monitoring system that can reconstruct filter type was developed based on ARM, DSP and FPAA. The dual-CPU consisted of ARM and DSP was used as the computing and control core of the system; FPAA was used to achieve that the filter type can be reconfigured; RT-Linux was imported as embedded real-time operation system, which achieved hiberarchy design of software and enhanced the operational stability and real-time performance of task assignment. Put into practice, it was confirmed that the system was effective.

Acquisition Device

The vibrator wireless monitoring system is designed based on Zigbee and the theory of compressive sensing. This system consists of the sensor wireless acquisition device, the vibrator wireless automation recorder and the vibrator remote management computer. Different modules of the system communicate via the Zigbee wireless network. The data to transmit is compressed by applying compressive sensing technology. As result, the quantity of the data transmition decreases sharply with the reliability and real–time operation being ensured. The system is already in use and the effectiveness is proved.

And Control

In order to reduce pollutant emissions to improve environmental protection, and maintain microgrid stability during real-time operation, a distributed energy optimization scheduling and stability control strategy was proposed. According to the distributed nature of the microgrid, as well as operational objectives of different microsources, an optimal scheduling model for microgrid environmental protection was designed. Based on the proposed model, the tasks of each unit in optimal scheduling and stability control were described. Genetic algorithm (GA) and user datagram protocol (UDP) were used to implement distributed optimization and control of the microgrid. The simulation indicates that, compared with the traditional centralized optimization and control, the proposed distributed optimization and control strategy can clearly show the characteristics of each unit, and have a faster computation speed. Meanwhile, it can timely response once the voltage fluctuates due to power imbalance, so as to keep microgrid stability in real-time operation.

Reactive Power Compensator

Wind power generation was developed rapidly in China. And many wind farms are configured Dynamic Static Var Compensators (SVCs) as reactive power compensator, which can meet the dynamic demands of the reactive power compensation for the wind farm. The paper put forward a coordination control strategy of reactive power for wind farm based on embedded real-time operation system in DSP, and by using LabVIEW to realize PC management and network communication management, and provides the research foundation for coordination and the optimal control of reactive power in large wind farm.

Architecture Analysis

It is crucial for real-time embedded system to design and verify for a little fault may lead to a catastrophe. Architecture Analysis and Design Language (AADL) is a modeling language used to design and analysis the architecture of real-time embedded system based on Model Driven Architecture (MDA). Code generation of AADL model to codes running on the Real-time Operation System can avoid hand-writing mistakes and improve the efficiency of development. Partitioning is introduced into embedded system to control fault transmission. This paper presents a mapping approach to generate codes from AADL model for partitioned system, and the generated codes which include configuration codes and C codes will run on a partitioned platform.
