This paper introduces the basic theory, structure, data transfer protocol of ds2450 1 - wire quad a / d converter, and the application of four channel digital storage oscilloscope
摘要介紹了ds2450單總線四通道模擬轉換器的基本原理、結構、數據傳送協議，以及在四通道數字存儲示波器中的應用。The card is a independent instrument which can do white - black video image digitization, eompresing, coding and transmit the compressed image data to host computer by rs - 485 bus, so the card can solve the bottle - neck problem of the video supervise system completely
該壓縮卡是一個獨立的視頻圖像壓縮和傳輸設備，它能直接對黑白電視信號進行數字化和壓縮編碼，並通過rs - 485總線將壓縮的圖象數據發送到上位機，徹底解決了視頻監控中的傳輸「瓶頸」問題。The card is based on the flat roof of pc machine, at first, we are used of the source of program data to leave in ide care, then binary file is come by the send out card, which is transmitted the standard ' s transmission stream. according to the european the standard of dvb - c, variable transmission current velocity rate is 9. 6 - 38. 4 mbits / s
此卡基於pc機平臺，首先將節目源數據以二進制文件的格式存放在普通ide硬盤上，然後通過計算機的pci總線將二進制文件經過發送卡轉換成符合數字電視asi （異步串列介面）介面標準的平穩碼流。根據歐洲dvb - c標準，可變的傳送流速率為9 . 6 ~ 38 . 4mbit s 。One - wire bus is a new technique based on cdma and std. it has simple structure, low cost, direct control via computer or microprocessor and simple program. the new type of one - wire digital sensor, which is integrated with thermometer, a / d, controller, rom, ram, can communicate with server computer through 1 wire and without any other accessories, moreover, 64 sensors can share one single line which makes system structure concise and easy
新型的單總線數字傳感器集成了溫度檢測、 a d轉換、控制器、 rom 、 ram 、單線雙向數據傳送等功能於一體，只需要1根數據線，無需其他輔助器件即可實現傳感器與主機間的數據通訊，而且多達64個數字傳感器可以共用該數據線，使系統間的連接非常簡潔，適應于低成本的多點測試、集中控制系統。1 ) realization of software packet embedded in m - es and md - is respectively to accomplish main function of mdlp, including assignment of tei ( temporary equipment identifier ), establishment of multiple frame operation, framing, flow control and error - free transmission of packets, is detailed. 2 ) a test model is established to evaluate the robustness and stability of mdlp and verify the validity of software packets. 3 ) according to the design of radio modem construction used in m - es, the modules of interface between data terminal equipment and radio modem are achieved to enable transmission of short message and continuous pseudo - random bit stream via rs232 uart
本文首先概述了蜂窩數字分組數據網的結構和空中協議，詳細分析了移動數據鏈路協議，並在此基礎上，重點敘述了以下方面的工作： 1 ）設計並完成了分別應用於m - es和md - is端無線控制器的兩套程序實現數據鏈路層的主要功能，包括分配臨時設備號、建立鏈路、組幀和面向連接的服務保證分組正確無誤地傳輸，並進行適當的流控； 2 ）建立測試模型測試移動數據鏈路協議的可靠性和穩定性，證明了程序包的效用； 3 ）根據cdpd系統無線數據機的軟硬體總體設計方案，完成了介面模塊，實現了rs232異步串口通信，使用戶可以根據需要發送短消息或連續的偽隨機比特流； 4 ）在tms320c54x的軟體、硬體模擬平臺上，建立了cdpd試驗模型，實現了cdpd系統的mdlp基本功能。Along with the growing technique of fieldbus, the traditional control system steps into a new phase, which is fieldbus control system ( fcs ). in order to meet the requirement of local instrument by fcs, it is significant and urgent to develop a smart transmitter with fieldbus communication
現場總線技術的發展導致了傳統控制系統結構的變革，形成了網路集成式全分佈控制系統?現場總線控制系統（ fcs ） 。針對fcs對工業底層儀表提出的新的要求，研製具有自主知識產權的全數字、網路化智能溫度變送器具有重要的意義。We use fieldbus technique controlling the boiler ' s running, instead of ddc and dcs controlling system. considering most boilers in our country were still using the normal analogy instrument and the whole digit intelligence appliance were not popularity
現場總線技術要求現場的設備傳送數字信號，需要使用智能儀表，但當前我國大部分鍋爐還是採用常規模擬儀表，全數字化智能儀表還未普及。分享友人
