WAN Monitoring System And Implementation

As embedded systems and 3G network development spurt in the country, IT hotspot areas and development of new technologies from the original direction of the transfer of computer network technology to the embedded system development.Microprocessor embedded system hardware platform of choice is particularly important.Compared with the industrial computer, embedded processor has its own distinct advantages: abundant type of product, technology is mature; and light weight, small size, low cost, reliability is relatively high, it is the choice of a large space, able to meet our requirements Various properties.How to better handle the huge embedded applications is the performance of our test of embedded hardware devices. At the same time real-time operating systems and embedded real-time software development, the choice is very important.Real-time operating system, now in a wide range of different kinds of software structure, applicable to a variety of environments of varying complexity, including the cyclic query system, front and back office systems, real-time multi-task system and multi-processor systems.Select the appropriate station and the whole wireless remote monitoring system is self-evident importance of RTOS because it may relate to the success of our entire system development.Therefore, to choose, we want to understand the characteristics and scope of the RTOS, compare their advantages and disadvantages, to find the most appropriate one.WAN monitoring system is based on traditional monitoring system, combined with the current wireless communications technology and communications processing technology and developed new remote monitoring system.It is for people to remote monitoring site to provide a great convenience.GPRS is General Packet Radio Service the English abbreviation is currently available in the GSM digital mobile communication system developed on a new data bearer service.Mobile communications technology and will combine IP technology, formed a mobile IP network, can be fixed with the rapid development of IP network to achieve seamless connectivity for mobile users in the form of packet-switched data, voice, images and other multimedia services.The emergence of GPRS service for wireless monitoring system provides a new wireless data transmission.It has changed in the past using the wireless transmission distance near real-time data transmission, or a small amount of the shortcomings of the poor, can provide cross-regional, high-speed, large capacity, high real-time data transmission services.This article first wide area network monitoring system status and development trend of the development discourse, and then describes an overview of the whole system framework design, and the system some of the basic components of each module.Then completed the circuit design aspects of the system, circuit design, including the core communication module board design, board design and power control module circuit board design, also described a number of chip features.Then, the data communication system is a detailed description of the technical solution, this system consists of four communication protocols, namely, the local background and the protocol and communications servers, ADSL protocol machine and the communication server, ADSL machines and mobile phones as well as monitoring and control module and communication protocol Server agreement.Finally, the system module due to environmental issues, anti-jamming performance of some of the measures taken.
