. Embedded Remote Monitoring System StructureBased on the remote monitoring of large equipment used in industrial production in the continuous operation status, this paper studies the embedded devices used for remote monitoring of major equipment. The system mainly includes the input/output module (netio) and the input/output module (netweb). The former is used to collect (input) field data ), or used for field device control (output). The latter inte

Original article address: Success Jun 28,200 5 Abstract: The maxim real-time clock (RTC) series includes several devices with a streaming charger, which can charge the second backup battery or capacitor. The battery or capacitor is used to maintain clock operation when the VCC powers down. The energy stored in the capacitor needs to maintain the clock for a c

real-time Linux operating system described earlier. The special dual-Kernel Operating System structure determines the particularity of application development. 1) Task Management Tasks in the system can be divided into real-time tasks and non-real-

the absence of the virtual storage technology. At the same time, the benefits of the virtual space can be much larger than the physical memory capacity, therefore, the virtual memory technology has been widely used in general operating systems. There are many similar examples, such as the indirect index query mechanism for file storage locations in UNIX file systems, even the Cache Technology in hardware design and the dynamic branch prediction techn

environment based on packet switching and the real-time multimedia application scenario, video coding should also consider the problems of network adaptive and fault-tolerant. Note: The following paragraphs, involving a lot of key technical terminology, no relevant background friends may be no concept, you can read Wikipedia entry to understand its specific meaning, key words: Predictive coding, intra-fram

asp.net Structure and background: There is a system, its structure and the general B/s ratio, there is a different place, is the bottom layer (said to be a layer, in fact, is a separate program), this layer is the WinForm program, for the time being "exchange" to express it. Mainly used for "external" communication, send and receive and process some information. Specifically do not repeat. So the structure of the system now is: Client--web Server (pre

Voltdb, the world's fastest relational database, and January 29, 2014 (EST) released the Next Generation Database 4.0 version number. The new version number has a lot of local improvements, and the big strides are quite high in system performance. In the past 13, Voltddb claimed that his company was more than 12, the annual revenue growth 298%, the predetermined amount of growth 368%, the number of customers increased 94%.There are several important highlights:1.
