计算机测控技术

1、异步串行通信接口通常指以下三类：RS-232(A、B、C)，20mA电流环和RS-422/RS485。

2、RS-232C：电气特性—采用负逻辑：-3v ~ -15v表示逻辑“1”，+3v ~ +15v表示逻辑“0”。

特征：由于RS-232C比较高电平输出，且正负输出，所以其驱动器需提供+10V以上的对称电源。

3、将TTL/CMOS信号直接连接：1米以内，最长不超过5米。

4、Page3（异步串行通信的直接连接、多机直接连接）。

5、MC1489是相应的4路RS-232C信号接收器，仅需5V供电。

6、MAX232A功能框图（P4图1.7）。

其功能是：将TTL的异步通信逻辑转换为RS-232C 逻辑电平。

（为什么要有转换部件?）7、上位机与多个串口设备通信时，每个串口必须使用1个独立的RS232C串口，可使用多串口卡，或多路串口接口芯片。

8、使用多串口卡连接多个串口设备的系统。

（P5图1.9）9、MAX488/490与RS422连线图（P6图1-10）。

为防止高频信号在连线中的反射影响通信质量，在接受端加接负载电阻式必要的。

10、总线方式的RS－422组网。

（P8图1-14）11、USB总线特点，以及其级联扩展。

（P17）12、长距离通信解决的问题以及解决方法（P18）。

13、长距离通信分为哪三种方法，各自的距离是多少？-用电流环实现隔离的长线通信，其距离见P18。

-使用RS-422/485的长线通信，通信距离可达1200米，更长的距离可通过中继器实现。

-使用光纤传输RS-422/485信号，通信距离可达20千米。

14、LED显示驱动方式，各自优缺点？1）静态显示：同时点亮，硬件较多，软件设计简单。

2）动态显示：轮流点亮，节省硬件，软件相对复杂，数码管较多，或为点阵显示屏时，常采用矩阵扫描方式。

15、LED为何要限流？由于LED的电流特性为近似的恒压器件，导通电流I在其导通阈值附近快速增大，所以必须加限流电阻控制电流值。

The thermal response of the model is driven entirely by thermal loading through film coefficients (no temperature boundary condition is applied in the model). Figure W3–1 shows the surfaces where the thermal loads should be applied. The reactor is initially at 70 °F. The outer surfaces of the reactor vessel assembly are exposed to air at 70 °F, with a film coefficient of 0.035Btu/h/in2/°F. The inner surfaces are in contact with water and have a film coefficient of 0.70 Btu/h/in2/°F. At steady state, the inlet water temperature is 508 °F and outlet water temperature is 538 °F. During a rapid cool down in the fuel core, a 30 °F outlet temperature drop occurs over a 45 second period, while the inlet temperature remains the same.W3.2Figure W3–1. Thermal loading regionsPreliminariesFrom the working directory for this workshop:../heat_transfer/keywords/reactor-htopen the input file w_reactor_ht.inp using your text editor. You will now add the surface-based film condition and initial temperature field definitions described earlier. Note: Since this model will be used in subsequent workshops to build the complete model and perform the analysis, it is important that you use the data stated and notdeviate from the workshop instructions. Otherwise, you may find it difficult to complete the subsequent workshops.Defining film conditions and the initial temperature fieldBefore creating film conditions, you will first specify amplitude curves that will be used to define the variation of the sink temperature and then create assembly-level surfaces that define the thermal loading regions.OutsideCold side water(inlet)Hot side water (outlet)Elevation = 220 inW3.3 1.Create an amplitude curve that describes the time-variation of the inlet watertemperature. Use the total time as the time span. Note that amplitude definitions are defined at the model level (i.e., after the *END ASSEMBLY option andbefore the first *STEP option). The required option is:*AMPLITUDE, NAME=water-inlet, TIME=TOTAL TIME0., 508., 1., 508., 1801., 508.2.Create another amplitude curve that describes the variation of the outlet watertemperature. Similarly, use the total time as the time span. The required option is: *AMPLITUDE, NAME=water-outlet, TIME=TOTAL TIME0., 538., 1., 538., 46., 508., 1801., 508.Note that the part-level surfaces and sets described in the previous workshop are available for use at the assembly level. In this model many of these surfaces will take the same “attributes.” Therefore, to avoid defining attributes on every surface, you can merge ones that will take common attributes into a single surfacedefinition and then define the attribute on the merged surface. Abaqus allowscreating a combined surface using the COMBINE=UNION parameter on the*SURFACE option (the surfaces being combined must be the same type; i.e., an element-based surface can be combined with another element-based surface, but not with a node-based surface).3.Create an assembly-level surface by combining all part-level surfaces that are incontact with hot side water (see Figure W3–1). The required option is givenbelow. This option must appear between the *ASSEMBLY and *ENDASSEMBLY options.*SURFACE, COMBINE=UNION, NAME=inner-hothead-1.inner-hot, seal-1.inner, vessel-1.inner-hotNote the naming convention of a part-level surface when used at the assembly level. The surface head-1.inner-hot refers to the part-level surface inner-hot of the part instance head-1, the surface seal-1.inner refers to the part-level surface inner of the part instance seal-1, etc.4.Create an assembly-level surface by combining all part-level surfaces that areexposed to air (see Figure W3–1). The required option is given below. A text file named w_reactor_ht_surfaces.txt is provided with this information. You may copy and paste from this file.*SURFACE, COMBINE=UNION, NAME=outerSurfacefull_bolt-1.ends, full_bolt-1.shankfull_bolt-2.ends, full_bolt-2.shankfull_bolt-3.ends, full_bolt-3.shankfull_bolt-4.ends, full_bolt-4.shankhalf_bolt-1.ends, half_bolt-1.shankhalf_bolt-2.ends, half_bolt-2.shankW3.4 full_nut-1.outer, full_nut-1.topfull_nut-2.outer, full_nut-2.topfull_nut-3.outer, full_nut-3.topfull_nut-4.outer, full_nut-4.topfull_nut-5.outer, full_nut-5.topfull_nut-6.outer, full_nut-6.topfull_nut-7.outer, full_nut-7.topfull_nut-8.outer, full_nut-8.tophalf_nut-1.outer, half_nut-1.tophalf_nut-2.outer, half_nut-2.tophalf_nut-3.outer, half_nut-3.tophalf_nut-4.outer, half_nut-4.tophead-1.outer,seal-1.outer,vessel-1.outer5.Specify the film conditions on the surfaces indicated in Figure W3–1. The firstfilm condition is defined on the reactor inner surfaces that are on the hot water side, varying with time by referring to the amplitude water-outlet. The second film condition is defined on the reactor inner surfaces that are on the cool water side, varying with time by referring to the amplitude water-inlet. The third film condition is defined on the reactor outer surfaces that are exposed to air. Note that film conditions are defined at the model level. The required options are:Note: In this workshop the time unit is seconds. However, the given filmcoefficients use hours as the time unit. Before entering the data, you need toconverts the time units for the film coefficients.** Film conditions on inner surfaces:** k = 0.7/3600 Btu/sec/in^2/F*SFILM, AMPLITUDE=water-outletinner-hot, F, 1., 0.000194444*SFILM, AMPLITUDE=water-inletvessel-1.inner-cool, F, 1., 0.000194444**** Film condition on outer surfaces** k = 0.035/3600 Btu/sec/in^2/F*SFILMouterSurface, F, 70., 9.72222e-06You will next define the initial temperature for the model.6.Specify an initial temperature of 70 °F for the entire model.

ing. For applications requiring a low profile, the DIP package provides a height of just 0.350". High Accuracy: With a maximum nonlinearity of ± 0.025% for the AD202K/AD204K (± 0.05% for the AD202J/AD204J) and low drift over temperature, the AD202 and AD204 provide high isolation without loss of signal integrity. Low Power: Power consumption of 35 mW (AD204) and 75 mW (AD202) over the full signal range makes these isolators ideal for use in applications with large channel counts or tight power budgets. Wide Bandwidth: The AD204’s full-power bandwidth of 5 kHz makes it useful for wideband signals. It is also effective in applications like control loops, where limited bandwidth could result in instability. Excellent Common-Mode Performance: The AD202K/ AD204K provide ± 2000 V pk continuous common-mode isolation, while the AD202J/AD204J provide ± 1000 V pk continuous common-mode isolation. All models have a total common-mode input capacitance of less than 5 pF inclusive of power isolation. This results in CMR ranging from 130 dB at a gain of 100 dB to 104 dB (minimum at unity gain) and very low leakage current (2 µA maximum). Flexible Input: An uncommitted op amp is provided at the input of all models. This provides buffering and gain as required, and facilitates many alternative input functions including filtering, summing, high-voltage ranges, and current (transimpedance) input. Isolated Power: The AD204 can supply isolated power of ± 7.5 V at 2 mA. This is sufficient to operate a low-drift input preamp, provide excitation to a semiconductor strain gage, or to power any of a wide range of user-supplied ancillary circuits. The AD202 can supply ± 7.5 V at 0.4 mA which is sufficient to operate adjustment networks or low-power references and op amps, or to provide an open-input alarm.

在区位号值上加32的原因大慨是为了避开低值字节区间。
由于GB2312原始编码与ASCII编码的字节有重叠，现在通行的GB2312编码是在原始编码的两个字节上各加128修改而形成。例如：汉字“啊”，编号为16区01位。它的原始编码为0x3021，通行编码为0xB0A1。
如果不另加说明，GB2312常指这种修改过的编码。
