Telephone Cable Monitoring System Based On DSP Design And Implementation

With the development of information technology,the technology content contained in military information security equipment is becoming higher and higher.XXX type field with line telephone communication system which is relatively advanced is one of our main current cable professional battle equipment,owning the fuctions of automatic switching,no-center working,mutual interference between users with light weight,easy-to carry and quickly installed,etc.However,the rapid development of information technology also brings some negative impacts on the research of military equipment.As saltatory evolution for the equipment technology,there are many problems or flawed existing between the performance of some equipment and the actual requirements.This article is aimed at studying and analyzing XXX field with line telephone communication system cannot realize real-time monitoring on the circuit of cut-off condition,in order to design a set of telephone cable monitoring system to make up for the inadequacy of its function.The paper firstly researches the structure and principle about the XXX field with line telephone communication system,Then according to the users of the system,we use monitor system of designed host machine to supervise the on-line condition of every extension set via roll polling.When themachine n receives the signal from the main machine and response information backl,the host would recordthat the extension is online and its distal line is normal in the whole system.from Otherwise,if the host engine cannot receive the response signal from machine n and after more than five cycles,n the basis of the condition of distal line abnormalities of the set engine,the main machine can be immediately issue a buzzer alarm to inform the watchkeeper to inspect and repair the problem.The main machine uses floating-point DSP processor which explores TMS320F28069 as the center monitoring system,and the set machine adopts single chip microcomputer which owns STM32F103C8T6 as the core design of a monitoring system.Regarding thehardware circuit,we complete the core board and Analog circuit of the host and extension machine,and also design a display circuit and the human-computer interaction circuit.We finish the software used in the machine program of main and set machine by C language under the environment of CCS6.0 and Keil a host under the MDK version 6.0.During the process of software,we focus on the analyzing and improvement about the polling algorithm of monitoring system and the human-computer interaction to make our system meet the high design requirements.Our research finally does the debugging and analysis for the completion of the monitoring system.The results shows that our desighed new monitoring system,reaching the expected purpose,has realized the basic functional requirements.Regarding some deficiencies,the paper analyzes and prepare to improve these flaws in the future research work in order to put the system into practical use as early as possible.
