動力環境監控系統的多種通訊模式

返回列表 来源：纵横通品牌发布日期： 2022.01.01 浏覽： 1次

随着信息技术的飞速发展，计算机技术的发展和動力環境監控系統的日益多樣化。此外，系統中使用的通信模式也不同，從單一的通信模式到不同的現代通信模式。

動力環境監控系統

動力環境監控系統通讯模式介绍

1、com通信模式

工作原理：控制軟件通過通信方式向設備發送請求，設備接收到請求後將設備數據傳輸到監視器，監視器軟件顯示采集的數據。

2、SNMP通信模型

工作原理：第一個控制軟件是SNMP代理。在SNMP通信模式下感應到通信狀態（代理）設備請求後，在接收到設備請求後，設備數據被傳輸到監視器軟件，監視器軟件顯示采集的數據。TREP包將自動加載到監控程序中。

3、TCP客戶端通信模式

TCP客戶端模式的工作原理：監控軟件以TCP客戶端模式發送串行服務器連接請求，串行服務器通過接收連接請求，將設備的數據通過設備傳輸到數據交換監控軟件。監視器還顯示采集的數據。

4、TCP服務器通信模式

TCP服務器上的通信方式、工作原理和監控軟件顯示采集的數據。

與TCP客戶端相比，TCP服務器通信方式：

TCP客戶端模式：系統軟件向串行服務器發送請求，因此需要在串行服務器上固定IP地址和端口號。內部網絡由用戶組成，用戶可以在不同點爲串行服務器分配固定的IP地址。

TCP服務器模式：由于串行服務器發送連接到系統軟件的請求，系統軟件需要設置IP地址和端口號。用戶組織適用于移動運營商的公共網絡，不能在網站上提供永久IP地址。

5、UDP通信模型

工作原理：控制軟件以UDP通信方式通過串行服務器鏈路發送請求，UDP硬件根據需要向監控軟件發送硬件數據，控制軟件顯示采集的數據。此通信方法不可靠，可能會丟失。

6、LonWorks通信模型

工作原理：首先，在Lon Works节点初始化后，Lon Works数据采集卡查询节点数据，Lon Works节点将节点数据返回给Lon Works数据采集卡。Lon Works数据采集卡将节点数据发送至Lon Works节点，Lon Works节点将节点数据返回至Lon Works数据采集卡。

7、Ops通信模型

工作原理：控制軟件通過OPC通信方式向OPC服務器發送連接請求，OPC服務器接收到連接請求後將信息傳輸到OPC設備。OPC設備將設備數據發送至OPC服務器，該服務器在與監控軟件交換數據後顯示采集的數據。

多种数据传输模式极大地促进了動力環境監控系統的获取，为数据的进一步多样化开辟了道路。

The light breakfast was taken, and the adventurers moved on. At each step the way grew more and more difficult. Every mile was steeper than its predecessor, and in many instances it was rougher. The rarefaction of the air increased, and rendered the work of breathing more and more severe. The travellers panted like frightened deer, and their lungs seemed to gain little relief from the rest that the Doctor and his young friends were compelled to take at frequent intervals. The last of the huts of refuge was passed, and it seemed only a short distance to the summit. But it required more than an hour's effort to accomplish this final stage. The boys refused all offers of assistance, and struggled manfully on; but Doctor Branson was less confident of his powers, and was glad of the aid of the strong-limbed and strong-handed yamabooshees. All were glad enough to stand on the summit and gaze into the deep gulf of the crater, while their brows were cooled by the clear breezes from the Pacific. They were at the top of Fusiyama, 14,000 feet above the level of the ocean that lay so far below them, eighty miles from their starting-point at Yokohama, and their vision swept an area of the surface of the earth nearly two hundred miles in diameter. East and south lay the broad ocean. West and north was the wondrous land of Japan, a carpet of billowy green, roughened here and there with wooded hills and small mountains, indented with bays and with silver threads of rivers meandering through it. It was a picture of marvellous beauty which no pen can describe. "I should like to know what you make of them," said Lawrence. "Ah well, be you a Fleming?" We have now to see how, granting Epicurus his conception of painlessness as the supreme good, he proceeds to evolve from it a whole ethical, theological, and physical system. For reasons already mentioned, the ethical development must be studied first. We shall therefore begin with an analysis of the particular virtues. Temperance, as the great self-regarding duty, obviously takes precedence of the others. In dealing with this branch of his subject, there was nothing to prevent Epicurus from profiting by the labours of his predecessors, and more especially of the naturalistic school from Prodicus down. So far as moderation is concerned, there need be little difference between a theory of conduct based exclusively on the interests of the individual, and a theory which regards him chiefly as a portion of some larger whole. Accordingly, we find that our philosopher, in his praises of frugality, closely approximated to the Cynic and Stoic standards—so much so, indeed, that his expressions on the subject are repeatedly quoted by Seneca as the best that could be found. Perhaps the Roman moralist valued them less for their own sake than as being, to some extent, the admissions of an opponent. But, in truth, he was only reclaiming what the principles of his own sect had originally inspired. To be content with the barest necessaries was a part of that Nature-worship against which Greek humanism, with its hedonistic and idealistic offshoots, had begun by vigorously protesting. Hence many passages in Lucretius express exactly the same sentiments as those which are most characteristic of Latin literature at a time when it is completely dominated by Stoic influences. J. A. “I thought I saw—but it’s gone!” Larry retorted, lowering his voice also. “The Everdail Emeralds!” Larry repeated the phrase sharply. “Why, Jeff! I’ve read a newspaper story about them, in a Sunday supplement. That’s the matched set of thirty emeralds——” "You are not fit to go," Felipa said resignedly, "but that doesn't matter, of course." Dr. Arbuthnot, a great friend of Pope and Swift, was also one of the ablest prose writers, "The Memoirs of Martinus Scriblerus," published in Pope's and Swift's works, and the political satire of "John Bull," a masterly performance, being attributed to him. "Blank your Captain," roared the voice; "I'm no Captain." "What's that?" said the Deacon, rousing to interest, but carefully putting his thumb down to mark the place where he left off. "O, open it, Maria," groaned Si, "and you'll likely find his name writ somewhere inside." "I do not understand your one thing or your other thing;" answered Turner—"but I know this, that we have paid the tax, and that we will pay it no more—but as for touching what belongs to the London folks—I'll tell you what, if we do set fire to London, by St. Nicholas! if I see my own son Tom taking a penny's worth, I will fling him into the flames!"
