remote data processor 中文意思是什麼
remote data processor
解釋
遠程數據處理機-
The monitoring system of remote electric quantity based on pstn obtains the electrical parameters of transformer by the data acquisition module, host computer dials every monitored station by roll polling. inferior processor transmits datas to the computer in superior monitoring center through pstn for storage and processing, to provide the analysis and statistics for the supervisor section. the system is simple and cheap, and it will have a good prospect of application in electrical system
基於pstn的遠程電量監控系統通過數據採集模塊對變壓器的電參數進行採集,主機通過「輪循」的方式,依次撥通每一個監測站點,下位機將檢測到的數據通過pstn公用電話網送到上層監控中心的計算機系統進行存儲和處理,以提供主管部門的分析和統計之用。 -
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。
