遠程撥號系統-
This project focus on r & d of remote information transfer between some device, especially in the water - quality monitoring system. after learning the architecture of the popular pstn dial - up network. vpn broadband network and gsm wireless network, a new solution for remote communication was proposed. under this idea frame a communication hardware platform and software was developed
本課題主要針對環境水質在線監控系統中的信息傳輸問題，對遠距離設備之間的信息傳輸方式及發展進行了研究，結合目前流行的pstn撥號上網方式、 vpn組網技術和gsm無線數字通訊技術，提出了一種新型的遠程設備之間信息傳輸與互聯的方案，並按照這個思路搭建出系統所需的硬體平臺，設計出實現這個方案的應用程序。 -
This paper gives the general design of the administration system in the broadband man. it also explains the detail implementation, such as the modules of the traffic accounting and radius ( remote authentication dial in user service ) programs, the control of the layer 2 switch ports, the distribution of ip address, and so on. during the building of the system, we greatly unproved the efficiency of snmp ( simple networks manage protocol ) trap and achieved the access control hi the broadband man
對以太網方式接入的用戶，利用802 . 1q 、 pvlan （私有虛擬局域網）等新技術實現了用戶數據隔離和安全性保證，並對用戶埠資源進行了統一管理和遠程自動控制，採用snmp （簡單網路管理協議）採集埠流量的方式實現了以太網用戶的按流量計費，詳細設計了具體的流量採集程序模塊組成和各部分的功能。 -
In hardware system design, we adopted the microcontroller of at89c51 as the main controller of inferior processor, it is used to connect the modem with the data acquisition module. mcs - 51 assemble language is used to program the software of the device to realize the data transmission between modem and inferior processor. when the electric power in the run is beyond the specified value, the inferior processor can dial the phone number of central computer automatically to send the alarm message through the communication line. using a single - chip microcomputer to control a modem to transmit remote datas are introduced in detail
隨后詳細地介紹了系統的總體設計思想和具體的實現過程。在硬體系統設計中，採用了at89c51單片機作為下位機主控制器，用於連接modem和數據採集模塊。通過使用mcs51匯編語言編寫程序，實現了下位機與modem之間的數據傳輸，同時實現了自動檢測負荷，進行撥號報警的功能，其中重點介紹了單片機控制modem進行遠程數據傳輸的方法。 -
You ll learn how to set up and configure a remote authentication dial - in user service server radius on a linux system to perform authentication, authorization, and accounting for users
您將學習如何在linux系統上建立和配置一個remote authentication dial - in user service服務器radius ，以執行對用戶的驗證授權和記帳aaa 。 -
We also make another type of thermometer that can be used not only for temperature but also for other applications such as temperature control, alarm operation, etc. moreover, in addition to displaying the temperature on a dial, some models are capable of sending temperature signals from remote locations for input into a centralized control system
這種溫度計不僅可進行溫度測定，由於帶有接點機構還具有溫度控制和報警機能。另外，指針指示的同時遠距離傳送溫度信號，還可輸入集中控制系統。
