Design And Implementation Of Multichannel Data Collecting System

Emergency communication system is used for the event of natural or man-made sudden emergencies to utilize synthetically communication resources and handle highly efficiently these events, which offer communication function. In application, this system easily is influenced, even destroyed by outside situation. Therefore monitoring system is introduced to monitor for assuring system reliability. Monitoring system mainly completes monitoring the running situation of the whole system software and hardware and when fault is happening. It offers the mechanism of notification, recommendation and restore itself. When accomplish monitoring system, data collecting system is applied to field data collecting.But there are some problems such as single method of collecting, investing cost and the requirement of advanced operating staff.The background of this schema is emergency communication system.After researching embedded technology and data collecting relevant technology, design multichannel data collecting system.The main tasks include several points as below:(1) According the problem of the single data collecting method,design multichannel in this schema.This system use IXP serial CPU of ARM family,because network data dealing capacity of this CPU performance well.In the design,consider traditional remote data collectiong only depending on network port,add the new data relevant collecting of serial port.When network failing, this collecting method may communicate among systems and collect device information through serial port.This not only enrichs collecting means,but also efficiently heightens the reliability of collecting system and application dimension.(2) In collecting methods,multichannel data collecting system combines active collecting to passive collecting.Collecting system, according the collecting requirement of monitoring system, uses active collecting methods and returns collecting information to monitoring system.When monitoring target of agent device arrive the limen,use passive data collecting method to offer the warning notification to monitoring system,which may heighten the flexibility of this system.Besides,in collecting method,not only use tradional collecting method of API,register , SNMP and so on,but also complete SMBIOS data collecting through WMI programming,which enrich the method of information attained further and heighten the veracity of collecting information.(3) Accomplish the design of the main functions of multichannel data collecting system. Define the corresponding data collecting format and design various communication source language, which can offer the convenience of transmits, ordering, setting, warning and so on.Based on the above achievement, data collecting agent in VC++ 6.0 platform and developing the core module of multichannel data collecting system are designed by c languge in Linux embedded host environment.The achievement of multichannel data collecting emulation platform vertifies the designing target of this system.The results demonstrate that the data collecting system meet the designing target.This system becomes more reliable and collecting information is more comprehensive.
