連線字串
英文
connection string-
This paper designs a network interface for digital stored - program - control exchange. this interface connects digital stored - program - control exchange from pcm, and connects ethernet from rj45
該網路介面系統一端通過pcm基群串列總線連接數字程式控制交換機，另一端經rj45口與以太網相連。Before the connectting between moden and other equipments, it works at the cammand mode, the cammand that is send to moden is used to set or manipulate the mode, after the connectting between moden and other equipments, it works at connectting mode, at that time, the cammand send from the computer is send to another computer which will pass the moden and telephone line. the moden control cammand is called " at " cammand, all the control manipulation is realized by sending the ascii character to moden, after the moden received the " at " cammand, it firstly judges the cammand, secondly, it analyses and executes the cammand, finnally, it executes a response by sending back a ascii character, during the deseign of below - computer, we introduce in detail the deseign of system hardware and system software, below - computer system hardware and system software, below - computer is made up of microchip collecting and controlling system, which finish the strobe and water level data collection, display and disposal, deal with the communication with the above - computer, the microchip is the centre of data dealing with, the peripheral equipments are made up of data collecttion module, control cammand input module, display module, execute output module, and long - distance communication module
在moden控制軟體的設計中，詳細敘述了moden正常工作時的幾個重要函數：初始化函數、撥號處理函數、應答處理函數、掛機處理函數，設計並調試了四個函數的通信程序，數據機工作時存在兩種模式，命令模式與連線模式，命令模式是針對功能設置的模式，連線模式是數據傳輸的模式。當數據機未與其他設備連接時，其處于命令模式，這時候下達給數據機的指令是作為數據機本身設置或操作用的；當數據機已經與其他設備連接時，其處于連線模式，所有在此時由計算機送至數據機的信息都將經由電話線傳送到另一部計算機上。專門使用於控制數據機的指令集被稱為「 at指令集」 ，對moden的所有操作（如撥號、應答、掛機等）都可以通過給moden發送ascii字元串來實現， moden在收到at命令后，先對命令進行判斷，接著分析和執行命令緩沖區中的命令，最後以自身的ascii字元對命令作出響應。Second, if a string is too long for a single line, you can wrap the string using the python continuation character : the backslash
第二，如果字元串用一行表示太長，您可以使用python連續字元：反斜線（ ）來對字元串進行折行。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。What in turn means is ? a separate connection pool is maintained for every distinct process, app domain and connection string
換句話說：一個獨立的線程池是與每一個進程，應用程序域和連接字元串關聯在一起的。Fieldbus is a kind of digital, bi - directional serial data transfer and multi - branch communication network which connects intelligent equipment and automatic system. can bus is used in communication between plc and can modules in this system
現場總線是連接智能現場設備和自動化系統的數字式、雙向串列、多分支結構的遠程通信網路，本系統將使用甚廣的can總線技術應用於plc以實現與輸入輸出模塊的通訊。Fieldbus is a double - direction, digital, mulnode communication network which interconnects the intelligent devices and automatization control devices, it is also called as infranet
現場總線是連接現場智能設備和自動化控制設備的雙向串列、數字式、多節點通信網路，它也被稱為現場底層設備控制網路（ infranet ） 。分享友人
