storage. It is characterized by the CPU time used for data collection, which requires a high processor speed, but the circuit is simple, the cost is low, and easy to implement, which can meet the needs of some image acquisition systems. A video image data acquisition method is proposed based on the TMS320C5402 chip. 1

0 Introduction the The country has proposed a "Smart grid" program and has developed a timetable for building a "strong smart grid". "Smart Grid" will achieve the "power flow, information flow, business flow," the integration of a high degree of integration. Intelligent substation is an important foundation and support of strong smart grid, it is in the center of the smart grid hub position. On the receiving of high-voltage power grid input,

applications; another way to capture this is Microsoft Visual C + + since 4. Version 0 begins to support videos for Windows (VFW), which makes video capture programming much easier, using VFW technology to increase the flexibility of video capture and reduce reliance on video devices. In vc++6.0, components such as Mciavi, Drawdib, Avifile, and AVICap are included. Through the coordination between them, can complete playback, editing, file management and video capture functions, for video image

In fact, we all know that 2010 can open 2008 or 2005 of the project, that is backwards-compatible, then we use the principle of backward compatibility to break the page does not detect security information this problem, ASP. NET allows us to configure in Web. config to use the request validation behavior of ASP. , This will not be an error when the page is submitted again.VS20

Abstract: USB data acquisition controller is used in PC-based systems. Because of its ease of use and high price ratio, it has occupied a majority of the original data acquisition control card market, not only has it been widely used in OEM equipment, but also has replaced the traditional PLC system in many occasions a

Welcome to the big Data and AI technical articles released by the public number: Qing Research Academy, where you can learn the night white (author's pen name) carefully organized notes, let us make a little progress every day, so that excellent become a habit!First, the introduction of flume:Developed by Cloudera, Flume is a system that provides high availability, high reliability, distributed mass log

Data acquisition is critical for some websites, and some of the following problems are encountered when developing this collection program:One, the single process acquisition slow, the acquisition task interval time cannot control.Second, the data download part and the analy

This poses a challenge to power quality monitoring. The monitoring

Development of data acquisition card driver in VxWorks [Date:] Source: China Power Grid Author: Yang, Yang smart, Li Xu, Li zhengxi [Font: large, medium, and small] 　 1 Introduction With the development of embedded technology, data collection is widely used in field equipment. Based on the actual p

Because the data acquisition station is basically installed in the field or the roof, the installation location and vibration have certain influence on the accuracy of the test data. So want to have a position state data, just found Kylin made on the ADXL345, such a digital output acceleration sensor. As shown in the r

development of a traditional data acquisition card requires a lot of knowledge of the reserve, especially related to low-level driver development, the difficulty is relatively large.

First of all, the background of the project, once done a project, according to the data in Excel batch to crawl the data on the Web page, the crawl of the data in bulk backfill to excel. There are many rows in this Excel record (there will be thousands of rows in many cases), and each row of data stores the criteria fo

Random acquisition of any row of data (rownum) in the oracle database, using lerownum Recently, when reading oracle data, I learned the concept of rownum. I used to only know how to add, delete, modify, and query database tables; After seeing the concept of rownum, I suddenly thought that many business scenarios should be applicable. For example, during random a

Data acquisition from November 24, 2013 to now has been 38 days. The midst of it was intermittent, but never ceased. Think back. The journey we have travelled can be divided into the following six areas:a preparatory work 1 Executing the documentAt first, Miss Rice asked us to come up with a plan for the implementation of this collection of data. A planning guide
