基于嵌入式系統(tǒng)的電機(jī)監(jiān)測(cè)可視化系統(tǒng)的開發(fā)
[Abstract]:As an important electrical equipment, motor is widely used in industrial and agricultural production and daily life. It is of great economic significance to monitor the motor on line in real time, to understand the running condition of the motor in time and accurately, and to ensure the reliable operation of the motor. The traditional motor monitoring system is mainly composed of 8-bit or 16-bit single-chip computers. Its logic operation ability is limited, the real-time performance of the system is poor, and the safety and reliability of the system is poor. With the development of computer technology, monitoring technology and embedded technology, many advanced motor monitoring methods have emerged. The appearance of 32-bit high performance microprocessor and embedded system makes the motor monitoring system tend to be miniaturized and intelligent. The direction of network development. A visual motor monitoring system based on embedded system is proposed in this paper. It can realize real-time sampling and on-line monitoring of motor voltage and current parameters. The system adopts the ARM920T kernel microprocessor S3C2440A of Samsung Company as the controller and the Linux operating system as the software development platform. The visual system of motor monitoring is constructed from the aspects of hardware and software respectively. In the aspect of hardware, the circuit design of each function module of the system is introduced in detail. In the aspect of system software, this paper introduces the software development platform of embedded Linux operating system, and the writing and modification of the drivers related to the system under the Linux operating system. This project mainly completes the development of the A / D converter and LCD driver. The embedded database SQLite, the embedded graphic interface development platform Qt, system database development and the Qt graphical interface are transplanted on S3C2440A. And the realization of data acquisition, FFT analysis and other programs in the application program, and provides a friendly man-machine interface.
