In the paper, the protocol adopt special route optimize algorithm and tdma time slot assigning algorithm, make node enter low consumption or sleep state in order to reduce the consumption ; aiming at choice the mechanism of cluster head, multi - hop routing and the mechanism of mac, the existing leach protocol is improved
本文的網路協議是採用特殊的路由優化演算法和tdma時隙分配演算法，使節點進入低功耗或睡眠狀態以降低功耗。協議主要在簇頭的選擇機制、多跳路由、 mac層通信機制等方面，對已有的leach協議進行了改進。 -
Second, the current routing protocols of wireless sensor network are analyzed, aiming at the disadvantage that the protocols have high power dissipation and short lifetime. based on the leach routing protocol, we improve the leach routing protocol, and then name the advanced routing protocol leach new, in which we improve cluster head selection algorithm and optimal cluster number determination of leach respectively
並重點對現有的無線傳感器網路路由協議進行了分析研究，針對這些協議存在的整體能耗高、網路生命周期短等缺點，在leach路由協議基礎上，對leach路由協議進行了改進，我們把改進后的路由協議稱為leachnew 。 -
In the leach - new protocol, the mainly improvement of the leach protocol exhibits as follow : for the sake of balancing the network load, the network choose the clusters based on the residual energy ; we take multi - hop communication between sensors instead of single - hop communication, which results in the reduction of energy consumption of clusters ; the new protocol finds the path to the cluster head with the minimum cost, using an algorithm similar to flooding to propagate the cost information and greedy algorithm to find the lowest cost link ; the algorithm for assigning tdma time slot reduces overall delays of network
在leach - new協議中，對leach協議的改進主要體現在以下幾個方面:根據節點剩餘能量選擇簇頭，以平衡網路負載;節點間採用多跳路由，降低簇頭能量消耗;節點根據能量消耗的代價來選擇至簇頭的路由，通過擴散演算法來廣播代價消息，採用貪婪演算法來選擇能量消耗最小的路徑;採用tdma時隙分配演算法減少網路時延。最後，利用ns2模擬軟體進行驗證。 -
Plc, robot and cad / cam are called the three major pillars in the modem factory automation. plc, as the head of the three, has become the leading basic automatic equipment in the field of the industry control in the early 1980s " but as a matter of fact, plc being with the lack of friendly man machine interface, rnakes no close relationship between human and machineometimes it even can not be promoted and applied in some fields aiming at the situation mat those imported products are too expensive while domestic products are of rare famous brands, a plc man - machine interface - plc monitor is developedthis paper systemically introduces the developing procedure for the whole system, including how to design hardware and software system. especially emphasizing plc communication protocol. real time message accessing, lcd controller instruction set, definition of data construction for message & tag screens and how to display thern, assignment of internal resource of cpuealization in software among plc & manitor, file format defining a nd download of user data, etcplc monitor will compensate some weakpoints of plc, and extend the application rangeimultanneously enhance the performance of plc and increase the attached value of mechanical machines, undoubtedly it will see hight market prospect
針對人機界面進口產品的高昂價格和國產品牌稀少的這一現狀，研製開發了一種plc人機界面? plc監控器。本文系統地介紹了整個系統的開發過程，包括硬體系統、軟體系統的設計及實現，重點介紹了plc通信協議，監控器的基本工作原理以及期望實現的功能，監控器電源電路、 sram存儲器掉電保護電路、 cpu監控器電路、按鍵輸入電路的設計及按鍵狀態的讀入，時鐘信息的設定與讀取， cpu液晶顯示器指令系統，信息畫面及標簽數據結構的定義及顯示方法， cpu內部資源的分配，監控器與plc通信的軟體實現，文件格式的定義以及畫面數據的下載等。 plc監控器彌補了plc一些方面的不足，可以擴大plc的應用范圍，提升機械設備的檔次，增加設備的附加價值，具有一定的市場前景。 -
Milan as a club will not face any action as their staff simply followed protocol by removing a player with a suspected head injury from the pitch
米蘭做為俱樂部不會受到任何處罰。俱樂部把疑似頭部受傷的球員換下場是正確地，並不會因為他們的球員可能受到處罰而負連帶責任。 -
Socket function mainly realizes setting up and initializing service unit socket, initializing service unit and service unit serial and so on. bind funcion primarily binds local address and port for the socket. listen function is to evaluate the max length of server ’ s listening queue. connect function and accept function set aside rate ahead, infrom user ’ s request of establishing virtual circuit to suna, cooperate with suna to establish the connection between client and server, return the result. we make use of three handshake with data protocol and virtual circuit mode, in this way, when we translate data, we can look up communication course according to virtual circuit number, at the same time, there aren ’ t source ip address and port, end ip address and port in the head of data package, the speed of translating data advances in a certain extent. send function and recv function is to send data collaborating with suna, and copy data from the receiving queue of socket to user ’ s buffer. close function cooperate
Socket （ ）函數實現創建、初始化服務元套接字，初始化服務元及服務元序列等。 bind （ ）函數為套接字綁定本地地址和埠號。 connect （ ）和accept （ ）函數主要是根據用戶要求預留帶寬，將用戶的建立虛電路請求轉達給服務元網路體系，協作服務元網路體系採用捎帶數據的三次握手協議建立虛電路，並告訴用戶處理結果，一方面，捎帶數據的三次握手協議在一定程度上可提高數據傳輸速度;另一方面，採用虛電路方式，使得數據通信可直接根據虛電路號查找相應的通信進程，而且數據包的包頭中省去了源ip地址、埠號和目的ip地址、埠號，提高了數據傳輸速率。 -
During the period from 1980 to 1993, he had assumed various positions at the bank of china including officer of the head office protocol division, foreign exchange dealer of new york branch, manager of treasury department at the boc paris branch, manager, and then deputy general manager of the head offices treasury department in february 1993
