Application Research Of CDMA Remote Intelligent Monitoring System

With the rapid development of wireless communications technology and the growing popularity of mobile communications, wireless monitoring systems in all walks of life are becoming more and more widespread. The researc based on CDMA network applications has became an important direction in wireless communications fields for its excellent network performance and good development prospects. The article based on the short messages and data services of CDMA network k, with the popular topics of "monolithic integrated circuits to control the CDMA module for wireless transmission", uses the Atmega128microprocessor produced by United States Atmel company and anydata wireless communications module DTGS-800made a monitoring data terminal which can complete wireless transmission with the pc in the control center.This topic completed the designe of hardware and software for monitoring data terminal.After the learning of main feature and detailed information it copleted the design in hardware circuit interfaces with the cdma module, man-machine interface used for data collection of the string mouth and other external circuits.Complete the software for application in date terminal the upper manage-ment software。 The management centre software was writed with visual basic6.0,it can complete the wireless data communications and data management between the terminal and control center.The data management software used in the terminal, monitor was writed with AVR assembly language.It telled the major function and the design imple-mentation It finished the design of initialization, of sendingdate, receiving date and the ppp connect to wireless transmission of data.
