Communication of remote measurement and control terminals in water supply SCADA system my company used to be through wireless digital radio to achieve, due to the external interference is too large, too high temperature prone to cause frequency deviation, resulting in frequent data is not received, with the water supply network remote detection and monitoring technology of the continuous development and progress, Now the popular CDMA or GPRS wireless communication in the stability or accuracy of

Abstract:The study of real-time video network transmission technology is of great significance for video applications. In this paper, an implementation diagram of a real-time video network transmission system is provided. Combined with the principle diagram, the key technologies of the real-time video network transmission system are analyzed: video collection, vi

Bluetooth baseband data transmission mechanism analysis zdnet network channel Update Time: Author: Source: Key words: Bluetooth Wireless Network Bluetooth is a new, open, low-cost, and short-distance wireless connection technology that can replace short-distance cables for wireless voice and data transmission. This effective and inexpensive wireless connectionThe connection technology can easily connec

Currently, many organizations have built internal lan. Most enterprise networks use twisted pair wires to connect to NICs for communication. Among them, twisted pair wires generally use 5 types of lines with a transmission rate of 100 MB. There are some differences between NICs. Many NICs adopt 10 Mbps/mbmps adaptive NICs, that is, the transmission rate automatically matches between 10 MB and MB. For such N

High-density and highly integrated OTN Wavelength-Division transmission SystemThis wave division multiplexing technology in the heyday, a variety of new technologies emerge. The goal is the same, that is to meet the network era of the operators. Long long ago, can only use CWDM coarse wave points, channel number is not enough to say, transmission distance is also very limited, line and equipment attenuation

Multicast routing is a good technology. It broadcasts data over the Internet. Unlike broadcast, due to broadcast storms, the router prohibits cross-route transmission of broadcast data. Multicast solves this problem. Currently, m$ software such as NetMeeting and WMS are widely used in multicast. Here we will discuss how to build your Linux into a multicast router.(Generally, gateways and routers do not support multicast data packets ). 1.

Before talking about the data transmission stage, we should first solve the historical issues left over. In usb_stor_bulk_transfer_buf (), row 406 has an interesting function called interpret_urb_result. This function is also from drivers/usb/storage/transport. c:265 static int interpret_urb_result (struct us_data * us, unsigned int pipe,266 unsigned int length, int result, unsigned int partial)267 {268 US_DEBUGP ("Status code % d; transferred % u/% u

Dynamic buffer for Network Data Transmission AnyChat has the buffer and file transmission function, which can realize the buffer and file transmission between the client and the client, as well as the buffer and file transmission function between the client and the server (added in V4.1 ). The buffer and file transfe

Android mobile phones and computers transmit data based on WiFi. Technically speaking, there are two main solutions: One is implemented through the FTP protocol, and the Android mobile phone is used as the FTP server during data transmission; One is implemented through HTTP. Android phones are used as HTTP servers during data transmission. Therefore, the technical difficulty lies in how our app implements F

expression and transmission of parameters in experimental instrumentsOriginal reason Description:In the different experimental instruments, the realization of signal transmission, in fact, can be converted to signal parameters of transmission. Therefore, the synchronization and refresh of each experimental parameter is the key to express the logic relationship of

With the rapid development of network information, the network affects all aspects of people, but the security problems that come with it become more and more prominent, so people's privacy requirements of network activities are more and more high. So the data encryption technology is born, the use of data encryption technology, to ensure that people in the network activities of data transmission security, while ensuring their own data and information

Wireless Network Transmission speed Comparison and Analysis Report This blog post is from the Bkjia blog haichuan. If you have any questions, go to the blog page for an interactive discussion! Blog: http://hichuann.blog.51cto.com/1024435/1584578 When purchasing a wireless router, which parameter is your most important? I believe that the answer from most users is wireless transmission rate. Yes, this fig

This article illustrates the TCP transmission of Java implementation socket. Share to everyone for your reference. The specific analysis is as follows: Client sends data to server * TCP transmission, the process of client establishment. * 1, create the TCP client socket service. The socket object is used. * It is recommended that the object be clearly defined as soon as it is created. The host to connec

This paper illustrates the data transmission UDP implementation method of Python network programming. Share to everyone for your reference. The specific analysis is as follows: First, the question: Do you think that tools like msn,qq on the Web transmit data mysteriously between machines? You want to play a little bit, too? Do you pass data between the two machines? Today let Python tell us the basic principles, of course, just to do simple understa

done after the connection is successful? After the success of the Bluetooth match, you can carry on the mobile phone and the computer before the file transfer and other operations, specific how to share files still have to continue to look down. Transfer files over Bluetooth 1, in the mobile phone and computer Bluetooth connection after the success of the computer will prompt pop-up link a successful dialog box, in this dialog box we have to use some of the functions. Mobile op

If you have two hard drives, with the dynamic volume features in Windows XP, you can greatly increase the speed of hard disk transmission. First, convert all partitions on the two hard disks to NTFS disk format. Next, open the Disk Management window, using the right mouse button to click on both hard drives, select the "Switch to Dynamic Disk" command in the pop-up menu, and convert all two hard drives to dynamic disks. Right-click on the black area

Usually we do a Web application when we need to login, login to enter the user name and login password, and, the user name and login password are clear text transmission, so it is possible to be intercepted halfway, especially in the Internet cafes and other occasions.Here incidentally an episode, I used to have a company, the office decoration time to arrange the network is relatively small, not enough, so I and another colleague used a hub to share

Based on the Apache FTP implementation file upload download tool, upload files need to consider the following issues (example is the continuation of the function): (1) Whether there is a directory for the FTP server, if the directory does not exist, you need to create a directory. (2), to determine whether the upload file already exists, if there is a need to delete before uploading or continued transmission. 1, upload or download the status of the
