NI 9472/9474 Terminal and Pin AssignmentsNI 9472/© National Instruments Corp.9NI 9472/9474The NI 9472/9474 with screw terminal has a 10-terminal,detachable screw-terminal connector. The NI 9472 with DSUB has a 25-pin DSUB connector. Each channel of the NI 9472/9474 has a terminal or pin, DO, to which yo u can connect a device. The eight digital o u tp u t channels are internally referenced to thecommon terminal or pin, COM. National Instr u ments recommends yo u provide independent COM and V s u p wiring for each channel of the NI 9472 with DSUB to minimize c u rrent flow in the COM and V s u p wiring. The COM pins on the NI 9472 with DSUB are internally connected..Note Yo u m u st u se 2-wire ferr u les to create a sec u re connection when connecting more than one wire to a single terminal on the NI 9472/9474 with screw terminal.Each channel has an LED that indicates the state of the channel. When a channel LED is lit, the channel is on. When the LED is dark, the channel is off. The LEDs are disabled when the chassis is in sleep mode. Refer to the Sleep Mode section for more information abo ut sleep mode.NI 9472/ Yo u m u st connect an external power s u pply to the NI 9472/9474. This power s u pply provides the c u rrent for the devices yo u connect to the mod u le. Connect the positive lead of the power s u pply to V s u p and the negative lead of the power s u pply to COM. The V s u p pins on the NI 9472 with DSUB are internally connected. Yo u can connect only one external voltage s u pply to the device. Refer to the Specifications section for information abo u t the power s u pply voltage range.CautionDo not remove or insert mod u les if the externalpower s u pply connected to the V s u p and COM pins is powered on.The NI 9472/9474 has c u rrent so u rcing o u tp u ts, meaning the DO terminal or pin is driven to V s u p when the channel is t urned on.Yo u can directly connect the NI 9472/9474 to a variety of ind u strial devices s u ch as solenoids, motors, act u ators, relays, and lamps. Make s u re the devices yo u connect to the NI 9472/9474are compatible with the o u tp u t specifications of the mod u le. Refer to the Specifications section for more information abo u t the o u tp u t specifications.Connect the device to DO and connect the common of the device to COM. Refer to Fig u re3 for an ill u stration of how to connect a device to the NI 9472/9474.Figure 3. Connecting a Device to the NI 9472/9474Increasing Current DriveEach channel of the NI 9472 has a contin u o u s o u tp u t c u rrent of0.75A, and each channel of the NI9474 has a contin u o u s o u tp u tc u rrent of 1A. If yo u want to increase the o u tp u t c u rrent to a device, yo u can connect any n u mber of channels together in parallel. For example, u sing the NI9474, if yo u want to drive 4 A of c u rrent, connect DO<0...3> in parallel as shown in Fig u re4. Yo u m u st t u rn all parallel channels on and off sim u ltaneo u sly so that the c u rrent on any single channel cannot exceed the 1A rating.Figure 4. Increasing the Current to a Device Connected to the NI 9474Wiring for High-Vibration ApplicationsIf an application u sing the NI 9472/9474 with screw terminal is s u bject to high vibration, National Instr u ments recommends that yo u either u se ferr u les to terminate wires to the detachable screw-terminal connector or u se the NI9932 backshell kit to protect the connections. Refer to Fig u re5 for an ill u stration ofu sing ferr u les. Refer to Fig u re1 for an ill u stration of the NI9932 connector backshell.Figure 5. 10-Terminal Detachable Screw-Terminal Connector with FerruleI/O ProtectionThe NI 9472/9474 is short-circ u it proof in accordance withIEC1131-2 and provides overc u rrent protection. Understanding Short-Circuit-Proof DevicesEach channel on the NI 9472/9474 has circ u itry that protects it from c u rrent s u rges res u lting from short circ u its. Whether the mod u le s u ffers damage from these overc u rrent conditions depends on the following factors:•The amo u nt of c u rrent thro u gh the channel•The amo u nt of time the c u rrent is above the c u rrent limit •The freq u ency of the c u rrent s u rgesWhen the amo u nt of c u rrent thro u gh the DO terminal or pin is greater than 13 A, the channel trips and goes into an overc u rrent state. In an overc u rrent state, the channel t u rns off and the mod u le is not damaged. If the c u rrent thro u gh DO is between 6 A and 13A, the state of the channel is indeterminate and depends on factors s u ch as the c u rrent level, the temperat u re, and the power s u pply. Higher inr u sh c u rrents that exist for less than the trip time do not trip the protection circ u itry. Refer to the Specifications section formore information abo u t the maxim u m contin u o u s o u tp u t c u rrent, short-circ u it behavior, and short-circ u it trip time. Yo u also can refer to the IEC 1131-2 standard for more information abo u t short-circ u it-proof devices.Tip Beca u se the NI 9472/9474 mod u le incl u des internalflyback diodes, yo u do not need to add external diodeswhen connecting to switching energy storing devices. Power Supplies and Overcurrent ConditionsIf a short-circ u it occ u rs, the c u rrent thro u gh DO can exceed the c u rrent rating for the power s u pply and the maxim u m contin u o u s o u tp u t c u rrent for the NI 9472/9474.If the power s u pply yo u are u sing with the NI 9472/9474 cannot s u pply more than 13 A, the mod u le may be damaged if ashort-circ u it condition occ u rs.Detecting an Overcurrent ConditionIf a device connected to the mod u le is not working while the channel is on, the mod u le channel may be in an overc u rrent state. Neither the software nor the mod u le LEDs indicate if anoverc u rrent condition occ u rs. A channel LED may be on even if the channel is off beca u se of an overc u rrent condition. To determine ifthe channel is in an overc u rrent state, meas u re the voltage between DO and V s u p. If the voltage is eq u al to the voltage of the external power s u pply connected to the mod u le, the channel is in an overc u rrent state.Resetting Channels After an Overcurrent Condition After yo u have determined and fixed the ca u se of the overc u rrent condition, reset the channel by t u rning it off. Alternatively, yo u can disconnect the external power s u pply from the mod u le. However, doing so disconnects power from all of the mod u le channels. Normal operation can res u me after yo u correct the overc u rrent condition and reset the channel.Sleep ModeThis mod u le s u pports a low-power sleep mode. S u pport for sleep mode at the system level depends on the chassis that the mod u le is pl u gged into. Refer to the chassis man u al for information abo u t s u pport for sleep mode. If the chassis s u pports sleep mode, refer to the software help for information abo u t enabling sleep mode. Visit /info and enter c s erie s doc for information abo u tC Series doc u mentation.Typically, when a system is in sleep mode, yo u cannotcomm u nicate with the mod u les. In sleep mode, the systemcons u mes minimal power and may dissipate less heat than it does in normal mode. Refer to the Specifications section for more information abo u t power cons u mption and thermal dissipation.

等差数列sn和an的关系

等差数列sn和an的关系全文共四篇示例，供读者参考第一篇示例：等差数列是数学中非常常见且重要的数列之一，其中每一项与前一项之差都相等。

在等差数列中，我们常使用两种常见的记号：S_n和a_n。

S_n表示等差数列的前n项和，而a_n表示等差数列的第n项。

本文将详细探讨S_n和a_n之间的关系。

我们来看S_n和a_n之间的关系。

设等差数列的首项为a_1，公差为d，则等差数列的第n项可以表示为a_n=a_1+(n-1)d。

而S_n表示等差数列的前n项和，即S_n=a_1+a_2+...+a_n。

接下来，我们来看一些具体的例子来说明S_n和a_n之间的关系。

假设我们有一个等差数列的首项a_1=2，公差d=3，我们来求该等差数列的前5项和S_5。

首先确定等差数列的第5项：a_5=2+(5-1)\times 3=14。

然后利用前面推导的公式计算前5项和S_5：S_5=\frac{5}{2}(2\times2+(5-1)\times 3)=5\times 8=40。

所以，当等差数列的首项为2，公差为3时，它的前5项和为40。

通过这个例子，我们可以看到S_n和a_n之间的关系是非常紧密和重要的。

在实际生活和工作中，等差数列的概念和相关公式会被广泛应用。

比如在金融领域中，等差数列常用来描述递增或递减的收入或支出情况；在物理学中，等差数列可以用来描述匀速运动的距离随时间的变化等问题。

S_n和a_n之间的关系是数学中一个非常重要的概念，对于理解等差数列的性质和应用起着至关重要的作用。

希望通过本文的介绍，读者能够更加深入地理解等差数列及其相关知识，从而更好地应用于实际问题中。

【2000字】第二篇示例：等差数列，顾名思义，就是数列中相邻两项之间的差值是相同的。

在数学中，我们常用字母a表示等差数列的首项，d表示公差，n表示项数，数列的一般形式可以表示为：an = a + (n-1)d，其中an表示第n项，a表示首项，d表示公差。

无线网络技术教程第二版习题答案20140406

第一章1.1如何理解计算机网络在现代社会的作用？答：现代社会生产生活中，网络技术实现信息互通和流动，高速完善的网络能使信息更快捷、准确的传输，发挥强大的作用。

网络已成为信息社会的技术命脉和知识经济的发展基础。

1.2请给出计算机网络协议的整体结构。

答：参考ISO/OSI模型以及TCP/IP模型。

1.3目前的骨干网络大多为光纤传输，部分城市实现了光纤到户，是否可以完全用光纤网取代所有其它类型的有线网络？试分析。

答：不能取代所有其他类型的有线网络。

电话线、有线电视线缆、双绞线、电力线等在生活中大量存在，许多也基本能满足不同实际需求，光纤铺设较复杂、成本较高，适于新建网络。

1.4 为什么网络协议栈都以分层形式实现？各层主要完成哪些功能？答：网络体系结构是一个复杂系统，所以采用结构化方法，将其分解为若干层次并设置相应协议，便于维护和更新。

各层次主要功能参考ISO/OSI模型以及TCP/IP模型。

1.5无线网络近几年得到了快速发展，试分析其原因并给出对未来无线网络发展的看法。

答：各种不同需求推动无线网络发展，未来发展体现多元化、便捷等特点。

1.6 从不同的应用目的角度，无线网络可以分成哪两大类？请列举各种无线网络技术，并分别归入这两大类。

答：根据不同的应用目的，无线网络可分为两大类：互联接入和物联传感。

无线局域网、无线城域网、卫星网络等，其应用目的是为用户访问因特网提供信息服务，属于互联接入。

物联网、无线传感网、无线个域网、无线体域网等，其应用目的是将网络触角延伸到传统社会信息之外的自然界、环境、物体、人体等，传输更为丰富多样的信息，属于物联传感。

1.7试分析和比较无线网络和有线网络，可从传输方式、组网结构等方面进行比较。

答：有线网络须架设电缆，挖掘电缆沟或架设架空明线；而无线链路则无需架线挖沟，线路开通速度快，将所有成本和工程周期统筹考虑，无线链路成本节省。

有线网络电缆数量固定，通信容量有限，而无线网络相对更灵活，随时增加链路，安装、扩容方便。

Warmfestigkeitseigenschaften).Die eingesetzten Schweißzusätze sind mit einem Werkszeugnis nach DIN EN 10204-2.2 zu bescheinigen.3.2 Anforderungen an den BetriebDer Herstellbetrieb muss in Anlehnung an DIN EN 729 Teil 3 seine Eignung in Bezug auf Einrichtungen, Verfahren und Per-sonal nachgewiesen haben. Alle Schweißarbeiten in der Werkstatt oder auf der Baustelle sind nur durch qualifiziertes Perso-nal (DIN EN 287 / DIN EN 1418) auszuführen und zu überwachen (DIN EN 719).Eine Verfahrensprüfung nach DIN EN 288 Teil 3 ist vor Fertigungsbeginn SMS Demag, Abt. Qualitätssicherung ASQ zur Ge-nehmigung vorzulegen.3.3 Schweißtechnische AusführungenZusätzlich zu den allgemeinen Fertigungsvorschriften der SN 200 sind nachfolgende Anforderungen einzuhalten:−Rücktrocknung von Schweißzusätzen ist nach den Angaben der SZ-Hersteller durchzuführen. Anschließende Warmhaltung der Schweißzusätze bei 100 – 150 °C.−Die Empfehlungen zum Schweißen metallischer Werkstoffe gemäß DIN EN 1011 Teil 1 und 2 sind zu berücksichtigen.−Hilfsschweißungen für Aussteifungen, Transportösen usw. müssen vollständig entfernt werden. Die Oberflächen der betref-fenden Stellen sind kerbfrei zu beschleifen und müssen mit einem geeigneten Verfahren auf Rissfreiheit geprüft werden.- Alle drucktragenden Schweißnähte sind mindestens 2-lagig auszuführen.4 FertigungEventuell notwendige Materialauszüge für die Blechbeschaffung, sowie für die Herstellung erforderlichen Fertigungsunterla-gen, z.B. Werkstattzeichnungen sind vom Lieferanten auszuarbeiten.Fertigungstoleranzen sind der Fertigungsvorschrift SN 200 und/oder der Zeichnung zu entnehmen.Grundsätzlich gilt, dass Anschlagösen in Absprache mit dem Besteller festgelegt werden. Die Lage der Ösen ist in einer Skiz-ze zu dokumentieren und zur Genehmigung an SMS Demag, Abt. Qualitätssicherung ASQ vorzulegen. Falls Anschlagösen nicht belassen werden können, sind diese restlos zu entfernen. Die betreffenden Stellen sind kerbfrei zu beschleifen und müssen auf Rissfreiheit mittels Oberflächenrissprüfung geprüft werden.Falls erforderlich, werden die Deckeltragarme, das Schwenkportal/Aufbauten und die Deckelbühne anschließend wieder de-montiert und je nach Transportmöglichkeit separat bzw. in größtmögliche Teile, mit entsprechenden Schweißnahtvorbereitun-gen an den Montageschweißstößen und Markierungen für die Endmontage versandt.Die Endmontage und das Zusammenschweißen erfolgt dann auf der Baustelle. Dazu eventuell notwendige, geeignete Trans-portaussteifungen sind vom Hersteller vorzusehen. Diese verbleiben bis zur Anlieferung auf der Baustelle am Bauteil.Werden einzelne Bereiche der Deckelbühne wassergekühlt, sind alle Kühlwasser Ein- und Ausgänge dauerhaft mittels Schweißraupen zu kennzeichnen (I → Eingang; O → Ausgang). Alle Kühlwasserkanäle müssen frei von Schmutz, Spänen, Schweißschlacke usw. sein.Seite 3SN 947 Teil 2 : 2003-12 5 Prüfung5.1 AllgemeinesBei allen Bauteilen ist eine visuelle Prüfung der Schweißnähte gemäß DIN EN 970 durchzuführen und zu dokumentieren. Oberflächenfehler wie Einbrandkerben, Zündstellen, Spritzer, scharfkantige Stellen usw. sind nicht zulässig und müssen ent-fernt werden.Der Umfang der zerstörungsfreien Prüfungen ist auf der Zeichnung bzw. in der SN 200 Teil 4 angegeben. Die für die Durch-führung und Bewertung anzuwendenden Normen sind in der SN 200 Teil 4 aufgeführt. Für die Ultraschallprüfung nach DIN EN 1714 gelten die Anforderungen der Prüfklasse A, Tabelle 5 für alle Wanddicken.Zur Vermeidung von Kurzschlüssen sind bei allen wassergekühlten Bauteilen sämtliche Kühlwasserkreisläufe mittels Druck-luft auf freien Durchgang zu prüfen.Die verschliffenen Stellen von entfernten Anschlagösen sind mittels Oberflächenrissprüfung auf Rissfreiheit zu prüfen.5.2 DruckprüfungIm Falle das einzelne Bereiche der Deckeltragarme wassergekühlt werden, sind die Kühlkanäle einer Druckprobe zu unter-ziehen:Prüfmedium: Wasser 1Prüfdruck: 10 barHaltezeit: 1 StundeKontrolle: durch ManometerNach der Prüfung muss das Wasser vollständig entfernt werden und Ein- und Auslaß sind mit Kappen bzw. Blindflansch zu verschließen6 WärmenachbehandlungEine Spannungsarmglühung ist funktionsbedingt nicht erforderlich. Eine Wärmenachbehandlung aus fertigungstechnischer Sicht ist vom Fertiger zu veranlassen.7 Anstrich und KonservierungDie Beschichtung erfolgt nach SN 200 Teil 7, soweit keine andere Angabe in der Zeichnung bzw. Stückliste angegeben sind.Die Deckelbühne wird gesandstrahlt und erhält eine hitzebeständige Grundbeschichtung nach SN 200 Teil 7 – 3.1.2. sowie eine hitzebeständige Deckbeschichtung nach SN 200 Teil 7 – 3.3.2.Die Schweißnahtvorbereitungen für die Montageschweißungen erhalten keinen Anstrich und keine Konservierung. Diese Be-reiche sind mit geeigneten Mitteln abzukleben.8 Dokumentation−Abnahmeprüfzeugnis DIN EN 10204-3.1B für Grundwerkstoffe−Werkszeugnis DIN EN 10204-2.2 für Schweißzusätze−Wärmebehandlungsprotokolle−Abnahmeprüfzeugnis DIN EN 10204-3.1B über zerstörungsfreie Prüfungen wie z.B. visuelle Prüfung, Eindring-, Magnet-pulver-, Ultraschall-, Röntgenprüfung−Abnahmeprüfzeugnis DIN EN 10204-3.1B Maßprotokoll mit Soll- und Istmaßen−Schweißanweisungen−Protokolle über DruckprüfungDer Lieferant stellt alle notwendigen Dokumente zu der Anlage zur Verfügung die nach den EU-Richtlinien zur Abgabe einer Konformitäts- oder Herstellererklärung durch SMS Demag notwendig sind.Die Anzahl der erforderlichen Kopien ist der Bestellung zu entnehmen.1in kalten Jahreszeiten und/oder bei längeren Lagerzeiten ist, ein Frostschutzmittel, abgestimmt auf die minimal zu erwartende Außentempe-ratur, zu verwenden.Seite 4SN 947 Teil 2 : 2003-129 Zeichnungseintragung (SMS Demag intern)Die Zeichnungseintragung lautet:Liefer- und Prüfvorschrift SN 947 Teil 2 beachten.Zitierte NormenDIN EN 287 Prüfung von Schweißern, SchmelzschweißenDIN EN 288-3 Anforderung und Anerkennung von Schweißverfahren für metallische Werkstoffe,Schweißverfahrensprüfungen für das Lichtbogenschweißen von StählenDIN EN 719 Schweißaufsicht; Aufgaben und VerantwortungDIN EN 729-3 Schweißtechnische Qualitätsanforderungen; Standard QualitätsanforderungenDIN EN 970 Zerstörungsfreie Prüfung von Schmelzschweißnähten, SichtprüfungDIN EN 1011-1 Empfehlungen zum Schweißen metallischer Werkstoffe - Allgemeine Anleitungen für Lichtbogen-schweißenDIN EN 1011-2 Empfehlungen zum Schweißen metallischer Werkstoffe - Lichtbogenschweißen vonferritischen StählenDIN EN 1418 Schweißpersonal-Prüfung von Bedienern von Schweißeinrichtungen zum Schmelzschweißen und von Einrichtern für das Widerstandsschweißen für vollmechanisches und automatisches Schweißen vonmetallischen WerkstoffenDIN EN 1714 Zerstörungsfreie Prüfung von Schweißverbindungen; Ultraschallprüfung von Schweißverbindungen DIN EN 10025 Warmgewalzte Erzeugnisse aus unlegierten Baustählen; Technische LieferbedingungenDIN EN 10029 Warmgewalztes Stahlblech von 3 mm Dicke an, Grenzabmaße, Formtoleranzen, zulässige Gewichts-abweichungenDIN EN 10204 Metallische Erzeugnisse – Arten von PrüfbescheinigungenSN 200 Fertigungsvorschriften der SMS DemagWeitere NormenSN 947; Teil 1 Schwenkportalsystem; Schwenkportal/Aufbauten, DeckeltragarmeSN490 GeländerfüßeDIN EN ISO 14122-1 Sicherheit von Maschinen; Ortsfeste Zugänge und maschinelle Anlagen; Wahl eines ortsfesten Zu-gangs zwischen zwei EbenenDIN EN ISO 14122-2 Sicherheit von Maschinen; Ortsfeste Zugänge zu maschinellen Anlagen; Arbeitsbühnen und LaufstegeDIN EN ISO 14122-2 Sicherheit von Maschinen; Ortsfeste Zugänge zu maschinellen Anlagen; Treppen, Treppenleitern und Geländer。
