TRICONEX 3564 Intelligent Urban Transportation System Based on GIS, RS, and GPS

With the acceleration of urbanization, the modernization and intelligence of urban planning and management have become more urgent and important. TRICONEX 3564 is located in densely populated large and medium-sized cities, surrounded by intricate streets and alleys, rows of skyscrapers, flying bridges, and various pipe networks. Faced with such a large and complex management system,

X-DO2401 985210203 A comprehensive application solution based on TD-LTE

The traditional emergency command and communication system mainly uses satellite communication vehicles as the working unit, and communicates with the command center through on-board telephones, X-DO2401 985210203 voice dispatch terminals. On site personnel can only communicate with the satellite communication vehicle and the command center through narrowband voice equipment such as walkie talkies, and cannot

X-DI3201 985210201 Introduce solutions related to IMOS

IMOS, also known as IP multimedia operating system, aims to create a multimedia development platform in the IP field. On the one hand, it supports monitoring, video, media publishing, VOD, and voice services, improving development efficiency and reducing maintenance costs. On the other hand, it also has a more long-term significance, laying the foundation for

X-AI3201 985210213 Design scheme of ONU end RS layer based on EPON system

Abstract: The design concept of EPON harmonic sublayer (RS) at the optical network unit end is proposed. Firstly, the functions to be implemented by the harmonic sublayer were introduced, followed by a systematic description of the design scheme and an introduction to each module. Finally, the workflow was provided. Introduction In recent years, with the

UAD149A1501 3BHE014135R1501 A Scheme of Convolutional Code Decoder Based on FPGA

Convolutional code is a commonly used error control encoding in deep space communication systems and wireless communication systems. It overcomes the disadvantage of block coding, which results in the loss of relevant information between groups due to encoding on a block by block basis. Convolutional codes (2, 1, 8) have been widely used in 2G

UAD149A0001 3BHE014135R0001 Design scheme of temperature control system based on ZigBee and GPRS

Abstract: According to the design requirements of temperature control systems, a temperature control system design scheme based on ZigBee and GPRS is proposed, and the hardware and software designs of the temperature control system are provided. The combination of ZigBee and GPRS wireless communication methods can achieve information transmission, which not only greatly reduces the

531X121PCRALG1 XML solves the data transmission problem of site-based remote monitoring systems

When solving the information transmission problem of a monitoring system, some difficulties were encountered, mainly due to the variety of data types in the system, the direction of sending, and the complexity of control. The introduction of XML files simplifies this issue. 1. Data communication of monitoring system Data communication is the use of data

VME7865RC V7865-23003 350-9300007865-230003 M A new automated networking solution based on a new type of serial port server

The device adopts a fully digital design, effectively avoiding the complexity and port security issues of traditional PCM networking methods. This scheme not

REX521GHHPSH51G A Discussion on the Development Method of Network Transmission Information Encryption and Decryption System

Computer network refers to a computer system that connects multiple computers and their external devices with independent functions located in different geographical locations through communication lines, and achieves resource sharing and information transmission under the management and coordination of network operating systems, network management software, and network communication protocols. From this perspective, the security factor

REX521BBHGLB01C On the Improvement Scheme of UDP Protocol in uIP

The full name of UDP protocol is User Packet Protocol, which, like TCP protocol, is used to process packets in networks. In the OSI model, in the fourth layer - the transport layer, it is on top of the IP protocol. UDP has the disadvantage of not providing packet grouping, assembly, and not being able
