无线移动平板校准操作流程

无线移动平板校准操作流程
点击病人菜单service的第一个login，密码******.然后进入系统，进去之后选择TUNE UP ,之后选择FD-，IN TABLE校正床下的无线移动平板，然后开启开关机背后的持续曝光按钮，准备0.6mm 的铜片，将床下托盘中的无线平板横放。

后面方格内有钩显示为被选中，然后选择右下角的NEXT，在你选择的一个程序下面又有两个程序，将第二个MOTO钩除，这个不需要选择，只选择第一个，然后点击GO，接下来屏幕上显示让您达到三个基本条件，做床下的移动平板，①是球管到平板的距离是130cm，我们可以调整球管高度，如果达到位置，屏幕上相应的提示；②是去除滤线栅，这个就需要把床下的托盘拉出来，然后球管中心也对好平板中心就可以；③是平板的温度，屏幕上会自动显示一个温度，提示你是否符合标准（正常室内温度要求为20-24度），如果平板温度过高或过低也不能做校准。

接下来点GO，后面连着两个提示，一个是问你是否把0.6毫米的铜片是否在对好中心后插进缩光器内，这时把铜片放置好，点击右下角的OK就可以了，然后自动做校准，床下的移动平板整个过程需要30分钟左右，这个是移动平板的校准。

平板校对完之后，一定要记得将先前拨动的开关回位！！！
在整个校准过程中注意不要突然断电，否则，对平板的伤害比正常使用断电更大，整个过程不要有人进入房间，不要触碰屏幕及键盘。

校准结束后会提示你是否成功，如果成功则有记录具体时间，如果失败会提示你具体原因，哪个没有通过则找个时间再做一次，如果还是没有通过就打800保修，会有工程师来处理，但如果校准没过一般不会影响使用，如果有其他问题一样打800保修。

平板天线制作方法

平板天线制作方法
平板天线制作方法如下所示：
1. 准备材料：金属板、直径为1/2波长的电缆（通常是同轴电缆）、焊锡、焊锡枪、螺丝刀和螺钉。

2. 根据需要选择金属板的大小，一般情况下金属板的长度为1/2波长，宽度为1/4波长。

3. 使用螺丝刀将金属板固定在所需位置，确保与地面保持良好接触。

4. 通过中心导线将电缆连接到金属板的一侧，使用焊锡和焊锡枪进行焊接。

5. 将电缆的外部屏蔽层剥离，将内部绝缘层露出。

6. 将内部绝缘层卷曲成圆形，并用焊锡固定在金属板的相对一侧。

这是为了实现天线的偶偶极性。

7. 完成焊接后，使用螺钉正确地将金属板和天线固定在所需位置。

8. 最后，将天线连接到所需的设备上，然后调整以获得最佳接收或发送信号效果。

需要注意的是，这只是平板天线的一种简单制作方法，实际制作过程可能会因天线设计和材料的不同而有所变化。

如果不熟悉电气安装或无线电原理，建议在制作天线前咨询专业人士或参考相关的文献。

When installingprobes in explosion hazardous areas the instructions included in the accompanyingprobe certification must also be observed.51.1ApplicationThe Silometer FM X 570 is designed for level measurement with a capacitance or hydrostatic pressure probe in safe or explosion hazardous areas. It possesses an intrinsically-safe sensor circuit conforming to EEx ia IIC and IIB. A list of certificated combinations is to be found in »Notes on Safety« preceding this chapter. A working system for level measurement comprises:•Silometer FMX 570 transmitter,•Capacitance, Multicap or Deltapilot S probe •Electronic insertSilometer functionThe capacitance or pressure measured by the sensor is converted into a frequency signal by the electronic insert located in its head. The Silometer FMX 570 supplies the power and receives a level-proportional frequency signal over a two-core cable. The signal is then processed to provide a level or volume measurement.Fail-safe operationIf a fault condition is detected, e.g. a break in sensor - transmitter cable, the analogue signal switches to -10 % or +110 % level or holds the last measured value. In addition,the alarm relay de-energises.211FMX 570mA10/4...20 mA,0/2...10V outputSilometer FMX 570transmitterLiquidsBulk solidsChannel 1Ex non-Exor orBA119Y01Fig. 1.1:Standard application showing Silometer FMX 570 controllinglevel measurement Capacitance probeDeltapilotfrequencyanalogdigitalcurrent voltagesens.

In both ca ses the mea sured va lue is processed by the electronic insert and passed on as a frequency signal.The probe and vessel form the two plates of a ca pa citor, the tota l ca pa cita nce of which ca n then be ca lcula ted from the formula :C tot =C 1+ 2πε0εr x LpF (1)--------------------------------ln (D/d)wherebyC tot =total capacitanceC 1=capacitance or feed through ε0=dielectric constant of airεr =rel. dielectric constant of productD=diameter of vessel d=diameter of probe L=length of probe immersed inproduct in metersIf the product conducts, the capacitance is determined by the thickness a nd properties of the insul a ting m a teri a l surrounding the probe. Equ ation (1)applies, whereby the variable D is now the diameter of the probe with insulation. In this ca se the ca pa cita nce va ries by a pprox.300 pF/m.Measurement is independent of dielectric constant and not affected by changes in this variable.In an open vessel, the level is derived from the hydrosta tic pressure exerted by a column of liquid on a probe placed at its foot. The pressure exerted is:p 1=ρ x g x h(2)whereby p 1 =hydrost a tic pressureρ =density of the liquidg =acceleration due to gravity h =height of the liquid column.Assuming a constant density, the level of the liquid ca n be ca lcula ted from the pressure measured by the Deltapilot.BA119Y05dLDC 1Fig. 1.3Capacitance measurement principleBA119E06dConductingproductLD Fig. 1.4Measurement in conducting mediaBA119Y07p 1 = ρ x g x hhatmospheric pressurep 1Fig. 1.5Hydrostatic measurement principleCapacitance measurementHydrostatic measurementMeasurement in conducting mediaSilometer FMX 570Chapter 1: Introduction72InstallationThis Chapter describes:•The probes for use with the Silometer FMX 570•Silometer installation in a rack or Monorack housing •Transmitter wiring •Sensor connection.•Technical data.Warning!•The Silometer FMX 570 transmitter must be installed outside explosion hazardous areas.2.1Probes and sensorsTable 2.1 lists the probes most frequently used with the Silometer FMX 570 transmitter.In addition to those listed, all probes which can be used with an EC 37 Z or EC 47 Z electronic insert can be connected to the transmitter. Installation hints can be taken from the appropriate Technical Information Sheet.Sensor constantsDeltapilot S sensors and EC 37 Z/47 Z inserts for capacitance probes are supplied with the sensor constants zero frequency »fo« and sensitivity »∆f« or »S«. For Deltapilot S sensors the constants are printed on a label stuck inside the sensor head, for inserts they are printed on the name plate, see Fig. 7.1, Section 7.3.Note these constants and enter them into fields V3H5 and V3H6 during commissioning,Section 4.1.

卫星平板天线的安装调试技巧

卫星平板天线的安装调试技巧作者：暂无来源：《声屏世界》 2015年第13期陈丹平板天线原理缝隙式平板天线是一种振子式平板天线的阵列式天线。

它可分为谐振式和非谐振式两种。

我们常用的是谐振式的，因为它的辐射方向是垂直于平板天线的，便于使用。

缝隙式平板天线尺寸很小，效率却很高。

一般缝隙式平板天线除去塑料外壳，内部由三层金属板构成。

最上一层称为缝隙辐射层,它是在金属板上面整整齐齐开凿了许多排列有序的裂缝。

这些大小一致的裂缝,相当于振子式平板天线的半波振子辐射单元,或者说每一个小裂缝就是一个缝隙天线单元。

而由这众多裂缝组成的缝隙天线阵就构成了平板天线。

这个有规则的裂缝大小尺寸恰好等于Ku波段平均波长的二分之一。

因此缝隙式平板天线的工作原理仍然符合半波振子天线的理论。

缝隙式平板天线的第二层是传导层，它起着将第一层缝隙辐射层的各个裂缝辐射元吸收来的电波信号通过各个对应“窗口”耦合到第三层波导馈电层或称之为波导传输层上去。

缝隙式平板天线的第三层与第二层传导层共同构成了波导的传输馈电电路，从而真正成为波导传输层。

平板天线与高频头一体化，使调节因素全部落到了天线上，无需调节高频头。

高频头是单一极化没有馈源的。

安装技巧安装平板天线，首先要把它指向正南。

其次要明确卫星信号是水平极化的，还是垂直极化的。

调节天线的方位角，可通过调节平板天线面与支撑杆之间的第三个调节环。

如果接收的卫星轨位高于所对应的正南方向卫星的轨位，就将平板天线向东转；反之如果接收的卫星轨位低于正南方向的卫星轨位，就将平板天线向西转。

调节仰角，调节平板天线面与支撑杆之间的中间调节环。

大体调节方位角、仰角后,再返回调节极化角。

在反射式抛物面天线中是调节高频头的极化角，而现在调节的是平板天线的面的极化角。

虽然两者的调节部位不一样，但两者调节的方法是相似的。

只要把平板天线的面看成高频头内的天线振子(俗称探针)，反复调节三个角，直到把卫星信号调出来。

安装技巧一：调试提高驻波比。

一、设计思路
1、wifi 天线非常讲究方向性，因此我们尽量设计出全向型辐射天线；
2、找到原 wifi 天线安装位置，挑选合适大小的磁性材料（在确保性能的前提下，为便于安装尽量选择较小尺寸的磁性材料），替换原 wifi 天线；
3、调试天线使得频率谐振在 2.4GHz-2.5GHz，避免信号回波损耗过高从而影响天线性能，有效频宽（2.4GHz-2.5GHz）驻波不得高于 2.0。

平板天线的理论和设计

平板天線的理論和設計〔上〕天線饋入方式分析方法平板天線的理論和設計〔下〕利用ADS設計平板天線結論｜在高效能的衛星、飛機、太空梭和行動通訊手機應用中，尺寸小、重量輕、低價位、高效能和容易安裝的天線會獲得較高的青睞。

平板天線就有外型小、適合平面和非平面的應用，和利用現在印刷電路板的低制作成本技術的好處，而且也容易和microstrip line circuit結合，使得平板天線成為現今一般最常用的天線之一。

平板天線主要的缺點有低效率、低功率、high Q、低偏極化純度、broadside directivity(無法作end-fired antenna)和頻寬非常窄等。

對國家或軍事的用途上，窄頻寬對傳送機密資料是一種好處。

對無線衛星行動通訊來說，平板天線有和高頻前端模組易結合的好處，且平板天線的指向性雖然很差，卻很適合應用在無線行動通訊系統。

本文首先介紹幾種不同feed in的方法。

因為高頻的功率放大器難作，功率很珍貴，要有最大的功率可以進入天線中，便要作好阻抗匹配的工作。

其次，將介紹二種平板天線的分析方法。

一是傳輸線的模型，另一則是cavity的模型，利用安捷倫科技的電腦輔助設計軟体ADS(Advanced Design System)實際設計幾個不同feed in的天線，然後作一總結。

天線饋入方式Transmission Line Feed圖1所示是利用傳輸線來feed能量進入天線中。

Feed in 點深入平板天線中對諧振頻率並不會有太大的影響，但卻可以改變輸入的阻抗值。

Feed in 點位置不同，輸入阻抗就不同。

一般對傳輸線的要求和對電路的要求一樣，均希望基板厚度要薄，介電常數要高才能把大部分的電磁場包在基板裡面。

但是對天線來說，卻希望基板厚度要厚，介電常數要低才能使大部分的場幅射出去。

因此，兩者之間有矛盾，須作一折衷，才能使得在不連續處有較少的幅射損失。

圖1Coaxial Feed圖2所示，是利用coaxial cable去feed能量到平板天線上。
