A sensor platform is a station equipped with extensive sensor and communication systems, which provide space based detection and alert capabilities. It consists of low-power, embedded computing devices known as motes, which use sensors to collect measurements from the physical world and its inhabitants. In this paper, an ARM-based sensor platform running a Linux Operating System is designed and implemented...
Based on ARM9 platform and the Linux operating system, this article studied on the methods of the video image capture and decoding. Take USB-camera image acquisition and image decoding for example, FrameBuffer and Video4Linux, two system interfaces for video image processing under the Linux operating system are introduced, and the collected images transferred from JPEG format to RGB format is displayed...
In this paper, the embedded web server, which take Samsung corporation's ARM9-S3C2440AL processor as core, is designed, it's operating system is Linux, the system hardware architecture is presented. Then the process of the Linux operating system being transplated on ARM is introduced. The realization of Boa and dynamic interaction between browser and the embedded system by using CGI are especially...
Recently, in the field of geological exploration, electromagnetic instruments have been tremendous growth, but they also have some typical shortcomings, such as big size, large power consumption, complex operation and so on. Therefore, base on the current development of electronic technology, this paper has discussed hardware and software design of the electromagnetic data acquisition system, which...
Aimed at the current situation that the domestic automatic meteorological data acquisition system is almost based the use of foreign products, a design method of multi-channel meteorological data acquisition system was given which based on ARM and CAN Bus. In the design, it fulfills the acquisition requirements of the analog signals, digital signals and intelligent sensor data through a combination...
Taking a water quality field analyzer as an example, a solution is proposed based on embedded and neural network. The hardware and the software design are introduced in detail. Then we sum up the complex nonlinear relation between the evaluation standard and the evaluation results through the continual study and training of BP neural network, and finally establish the BP neural network model. The...
This paper discusses an embedded access platform, which takes S3C2410 as the center core and is built upon the Linux operating system. Based on the character and advantage of ZigBee and GPRS, this article advances the solution scheme of the wireless sensor network gateway. Mainly analyzes the software design of the gateway, including the way to realize the connection of ZigBee protocol and GPRS network,...
Taking an instrument in transformer winding distortion measurement as an example, a solution is proposed based on Samsung's S3C2410 processor and embedded Linux operating system Hardware design is introduced, and software design also is described. The application of the artificial neural network technique to the frequency response analysis method (FRA) which is used to detect transformer winding deformation...
By applying CAN (controller area network) bus , a new type of LAN (local area network) embedded NC system based on ARM9 and motion control chip MCX314As is designed. Through CAN controller MCP2515 and CAN receiver MCP2551 , the LAN NC system is established. In the paper, the function of network system and the architecture of embedded NC system are described in detail. And a hardware platform of embedded...
