In this protocol, the transmitter organizes the frame according to it, and the receiptor does validity check of the characters, length check, crc check. thus, the system will work more exactly and efficiently. and based on rs - 485 communication, the paper implements a process communication method, which is impulsed by overtime message of timers ’ check
在這種協議中，發送方根據協議組幀，接收方主要採用了字元合法性校驗、長度校驗、內容的crc校驗，提高了通信的效率及正確性，最後在rs - 485通信上實現了基於定時器超時檢測消息驅動的進程通信策略。 -
To ensure the reliable transmission of voice and data, the channel encoding method which the digital trunking communication system uses is crc ( circle redundant code ) & rcpc ( rate - compatible punctured convolution code ) & interleave
為了保障話音和數據的可靠傳輸，數字集群系統採用的通道編碼方案為crc + rcpc +交織。 -
The method generates a random sequence to identify the original recipient of the document by user register. then it uses the crc error coding technique to form a watermark sequence
即通過用戶信息注冊，產生與文本對應的一個偽隨機序列號，加入crc糾錯碼后，形成水印序列。 -
Thereafter, the fractal dimension value of cracks distribution was presented as an effective index to appraise the corrosion level. relations between fractal dimension and rebar corrosion ratio, concrete deterioration factor and strength of the member were studied respectively. fractal nn model was also built up to predict the ultimate load bearing capacity of crc members obtained from the field corroded structures, good results are achieved, which could provide an applicable method to evaluate the durability of crc members
揭示出受腐蝕鋼筋混凝土構件在荷載作用下表面裂縫分佈服從統計意義上的分形，並對其進行了分形描述；提出以裂縫分形維數作為受腐蝕程度的有效衡量指標，首次實現了構件受腐蝕程度的定量描述；建立了裂縫分形維數與鋼筋銹蝕率、混凝土劣化系數、構件承載力之間的定量關系，並建立了分形神經網路模型對實際受腐蝕鋼筋混凝土構件進行了極限承載力的預測，取得了較好的預測效果。 -
The aouthor of this thesis worked in crc dalian branch for many years, after assay and summarize the condition of crc, the newly network technology and the development of boss, he bring forward the informatization plan of crc dalian branch. the thesis begins from the design and application of office automation system, then describes the amelioration method of the billing system, at last it puts forward the dicision surport system which bases on the database of billing system, and all of those compose the business operation supporting system
本文從大連公司的辦公自動化系統著手，從網路設計到軟體實現；然後根據鐵通總部的計費二期工程改造公司現有計費帳務系統，以適應公眾運營及新業務需求；在上述兩套系統建設改造完畢后，將以計費系統用戶數據為核心數據庫，建立大連分公司的決策支持系統，最終完成整個鐵通業務運營支撐系統的設計。 -
And software method can resolve d channel ' s work for its less data communication ; 3 ) cpu 80c152 is synchronized with mc145572 by a simple synchronous circuit, avoiding the complex fpga interface circuit ; 4 ) data transmission use dma, which reduces the delay of data transmission and cpu occupying ; 5 ) 8bit software look - up table method can achieve 16bit crc quickly, which reduces the resource of both hardware and software
對通信數據量相對小的d通道，採用軟體實現裝幀與解幀。第三，採用結構簡單的外部同步時鐘電路實現80c152和接入晶元mc145572的同步傳輸，巧妙地避開了復雜的fpga介面電路。第四，利用dma技術完成數據快速收發，降低了數據傳輸時延及cpu佔用率。 -
Thedly, the method of cyclic redundancy check ( crc ) in system softwar design was used to ensure the serial conununication reliability betwen contactless ic card and reader
第三，在系統軟體設計中採用crc校驗碼檢錯、出錯重發相結合的方法確保非接觸ic卡與讀寫器串列通訊可靠。
