Network is applied to government , school and company widely . the user cares more and more to how monitor terminal , device and running condition of network to insure network works well 随着网络在政府、学校、企业等领域中的广泛应用,如何对网络用户、网络设备及网络运行状况进行实时监控,以保障网络处于正常且高效的工作状态,成为应用者愈来愈关注的问题。
Aircraft noise and flight tracks are monitored around the clock by the aircraft noise and flight track monitoring system , which comprises 16 noise monitoring terminals installed at various areas under or near landing and take - off flight paths 民航处亦利用飞机噪音及航迹监察系统,全日二十四小时密切监察飞机噪音及航迹,这套系统设有16个分布在升降航道或其附近的固定噪音监察站。
Cortex monitor terminal is an integrated command ranging and telemetry system , which based on pc architecture and windows nt operating system . the cortex monitor terminal contains many functions , such as telemetry processing , satellite telecommanding , satellite ranging and simulation Cortex测控终端是基于pc结构、 windowsnt操作系统,具有卫星数据遥测、遥控,卫星测距和模拟、测量等功能的遥测遥控集成处理系统。
The remote control will be improved for the reason . firstly , this paper makes researches on remote control systems . it presents that a remote control system can be composed of three subsystems - monitoring terminal , transmission and online control , detailed research on a remote control system is conduct from three aspects , which are control methods , factors influencing system operation performances 本文首先对基于因特网的远程控制系统进行总体分析,认为一个远程控制系统应该由现场监控(或称被控方) 、网络(远距离数据传输) 、监控远程方(或称施控方,借助远程数据对控制过程进行监视和控制)等三个子系统构成;并从控制方式、影响控制正常运行的三个因素等方面对远程控制系统进行了探讨。
In order to solute these disadvantages , we find that we can apply the gsm common network to transport data . that is , we use gsm modem that can support short message service to transport alarm information connecting with the single chip system through standard rs232 interface . we can make the data transported wireless , and the monitor terminal is not only pc , but also mobile telephone or other mobile terminals 针对这种情况,我们可以利用gsm公共网进行数据传输的方法,即在传统的单片机系统中利用支持短消息业务的gsm引擎模块发送报警信息,通过标准的rs232接口结合已有的单片机系统,利用现有的900m或1800m的gsm网络,实现数据的无线传输,而监控终端也不再仅局限于pc机,也可以是移动电话或其他移动终端。
