An aggregation terminal of the power communication system is proposed in this paper. The terminal takes Samsung Corporation's ARM9 S5PV210 processor as the hardware core, embedded Linux as the operating system. The high-definition network camera is used as the video monitor device, whose interface is Ethernet. The terminal is equipped with 3G/4G LTE and various communication modules and the drivers...
The increase in the capacity of main memory coupled with the decrease in cost has fueled the development of in-memory database systems that manage data entirely in memory, thereby eliminating the disk I/O bottleneck. However, as we shall explain, in the Big Data era, maintaining all data in memory is impossible, and even unnecessary. Ideally we would like to have the high access speed of memory, with...
The embedded system takes the application as a center, which can adapt the strict demands of application system well to the function, reliability, cost, size and power consumption etc. Freescale Corporation's PowerPC series chip has the powerful communication capacity, the system stability as well as disturbance rejection ability. The CAN bus obtains the universal applications in the industrial control...
Combining with the characteristic of Web technology and field working requirement, Embedded Web Server (EWS) integrates the information acquisition and diffusion into the field embedded measurement and control equipments by the standard interface and communication protocol. And the EWS in the equipments can provide the browser-based operation and control interface through Internet. Ethernet for Plant...
Modbus protocol is widely used in the industrial control field because of its excellent reliability, flexibility, real-time performance etc. It becomes one of the international actuality industrial standards and including lots of industrial equipments using Modbus as their communication protocol such as PLC, DCS, intelligent instruments etc. Embedded system focus on applications, and it can adapt...
With the rapid development of the embedded computer technology, the new generation of industrial automation data acquisition and monitoring system, which takes the high performance of embedded microprocessor as its core, adapts well to the application system. It meets the strict requests of the function, reliability, cost, size and power consumption, etc. In the industrial automation application system,...
