3 Conclusion
The system can automatically control and display all signals,detect malfunction,give alerting signals and print .It has a multi-function alarm.For example,CRT terminal displays the number of fault channel,the level of alarm ,the value of parameters and the time when the limit is broken; the optical screen displays the number of fault channel in shining red light; sonic alarm gives alerting signals of corresponding level ; the printer automatically prints the number of fault channels,the level of alarm ,the value of parameters and the time when the limit is broken.The system can extend alarm in given place when given time limit is exceeded .
The system’s feature lies in adopting singlechip computer for the nucleus which make its hardware in terface circuits very convenient .It has giant potentiality to be extended and higher capability-price rate .After having been designed and manufactured successfully,the system has suffered long-time continuous operating test and all characters having been measured satisfied the national relevant standardized technical requirements .It has been confirmed that the system has filled up the blank in South-Center areas among voyage monitoring devices .

3.结论
本系统可自动控制及显示所有信号,检测故障,发出警报以及打印.它拥有一个多功能警报装置.比如,CRT终端显示错误通道的号码,警报等级,变量值及超越警戒值的时间;光学显示屏通过亮红灯表示错误通道的号码.声音报警器发出与警报等级相对应的警报声;打印机自动打印出所有错误通道的号码、警报等级、变量值及超越警戒值的时间.当一个地点的警报响动超过给定的时间时,系统会将警报扩展到其他地方.
该系统的特点即使用单片机作为它的核心,这使得它的硬件接口电路操作非常方便.它的升级潜能巨大,更高性价比.本系统成功推出后,它已经历了很长时间的操作试验,各项指标均符合国家相关标准技术要求.值得强调的是这一系统的研发成功填补了中南部地区在海航监控设备的空白.
