Abstract

An antenna lifting device is provided with an antenna unit and a lifting mechanism which brings up/down the antenna unit in the vertical direction. The antenna unit is provided with an antenna, an antenna supporting mechanism which supports the antenna, and an elevation angle adjusting mechanism configured to adjust the elevation angle of the antenna. The elevation angle adjusting mechanism adjusts the elevation angle of the antenna by rotating the antenna supporting mechanism, and the elevation angle can be adjusted independently from operation of bringing up/down the antenna unit by the lifting mechanism. Since the elevation angle of the antenna can be discretionary adjusted, electromagnetic wave measurement can be performed more accurately.

Description

天线升降机及电磁波测量系统Antenna Lifter and Electromagnetic Wave Measurement System

技术领域 technical field

本发明涉及一种天线升降机及具备该天线升降机的电磁波测量系统。The invention relates to an antenna lifter and an electromagnetic wave measuring system equipped with the antenna lifter.

背景技术 Background technique

为了对电子仪器的电磁妨害波进行评价，进行从该电子仪器发出的电磁波的测量。该测量是在电波暗室内或瞄准器(open sight)进行的。作为在电磁波测量中使用的装置或系统，例如有专利文献1～3公开的技术。但是，专利文献1～3公开的装置或系统具有无法调整天线的仰角的问题。In order to evaluate the electromagnetic interference wave of the electronic device, the measurement of the electromagnetic wave emitted from the electronic device is performed. The measurement is made in an anechoic chamber or with an open sight. As an apparatus or system used for electromagnetic wave measurement, there are techniques disclosed in Patent Documents 1 to 3, for example. However, the devices and systems disclosed in Patent Documents 1 to 3 have a problem that the elevation angle of the antenna cannot be adjusted.

相对于此，专利文献4公开的装置具备对应于天线的垂直位置来自动调整天线的仰角的机构。In contrast, the device disclosed in Patent Document 4 includes a mechanism for automatically adjusting the elevation angle of the antenna in accordance with the vertical position of the antenna.

专利文献1：日本特开2007-033254号公报Patent Document 1: Japanese Patent Laid-Open No. 2007-033254

专利文献2：日本特开平08-146063号公报Patent Document 2: Japanese Patent Application Laid-Open No. 08-146063

专利文献3：日本实公平03-006013号公报Patent Document 3: Japanese Publication No. 03-006013

专利文献4：美国专利第5379048号公报Patent Document 4: US Patent No. 5379048

但是，在专利文献4的测量系统中，由于只能调整确定的仰角，所以存在调整不充分的情况。另外，在专利文献4的测量系统中，由于无法测量高度有较大不同的被测量仪器，所以必须对每个被测量仪器准备测量系统。However, in the measurement system of Patent Document 4, since only certain elevation angles can be adjusted, the adjustment may be insufficient. In addition, in the measurement system of Patent Document 4, since it is not possible to measure instruments with greatly different heights, it is necessary to prepare a measurement system for each instrument to be measured.

发明内容 Contents of the invention

因此，本发明的目的在于提供一种具备可以更加柔软地调整仰角的机构的天线升降机。Therefore, an object of the present invention is to provide an antenna lifter provided with a mechanism capable of more flexibly adjusting an elevation angle.

本发明的一方面提供一种天线升降机，其具备天线单元、使该天线单元在垂直方向升降的升降机构，其中，所述天线单元具备天线和仰角调整机构，所述仰角调整机构被构成为在与所述升降机构使所述天线单元的升降独立开来的状态下，来调整所述天线的仰角。One aspect of the present invention provides an antenna lifter that includes an antenna unit and a lifting mechanism that vertically lifts the antenna unit, wherein the antenna unit includes an antenna and an elevation angle adjustment mechanism, and the elevation angle adjustment mechanism is configured to The elevation angle of the antenna is adjusted in a state in which the elevation of the antenna unit is independent from the elevation mechanism.

发明效果Invention effect

在现有技术中，由于天线的升降动作和仰角调整是关联的，所以若不正确设定它们的关系，在天线的指向性极高时等就不能进行正确的测定。相对于此，根据本发明，由于可以独立控制天线的升降动作和仰角调整，所以在任意的高度都可以将仰角调整为最贴切的状态。如此，根据本发明，可以进行柔软的仰角调整，因此，可以进行高精度的测定。此外，根据本发明，由于可以作为独立于高度位置的值来调整仰角，所以即使对于高度不同的被测量仪器，也可以由一个天线升降机应对。In the prior art, since the up and down operation of the antenna is related to the adjustment of the elevation angle, if the relationship between them is not set correctly, accurate measurement cannot be performed when the directivity of the antenna is extremely high. On the other hand, according to the present invention, since the lifting operation and elevation angle adjustment of the antenna can be controlled independently, the elevation angle can be adjusted to the most appropriate state at any height. In this way, according to the present invention, it is possible to perform soft adjustment of the elevation angle, and therefore, it is possible to perform high-precision measurement. In addition, according to the present invention, since the elevation angle can be adjusted as a value independent of the height position, even for measuring instruments having different heights, one antenna lifter can handle them.

具体实施方式 Detailed ways

参考图1，本发明的实施方式的电磁波测量系统具备天线升降机100以及与天线升降机100分开配置的旋转台200。在旋转台200上搭载有被测量仪器(EUT)300。Referring to FIG. 1 , an electromagnetic wave measurement system according to an embodiment of the present invention includes an antenna lifter 100 and a turntable 200 disposed separately from the antenna lifter 100 . An instrument under test (EUT) 300 is mounted on the turntable 200 .

如图2以及图3所示，天线升降机100具备天线单元130以及使天线单元130沿垂直方向升降的升降机构110。As shown in FIGS. 2 and 3 , the antenna lifter 100 includes an antenna unit 130 and an elevating mechanism 110 for vertically elevating the antenna unit 130 .

如图2以及图3所示，升降机构110具备：沿垂直方向延伸的天线杆112；以及由天线杆112连结的上侧部件114及下侧部件116。在上侧部件114设有上侧滑轮118，在下侧部件116设有下侧滑轮120。在上侧滑轮118和下侧滑轮120上架设有带122。如图4所示，下侧滑轮120经齿轮箱124连接于电动机126。这样，通过电动机126进行带122的驱动。作为这种电动机126，例如可以使用伺服电动机。As shown in FIGS. 2 and 3 , the elevating mechanism 110 includes: an antenna rod 112 extending in the vertical direction; and an upper member 114 and a lower member 116 connected by the antenna rod 112 . An upper pulley 118 is provided on the upper member 114 , and a lower pulley 120 is provided on the lower member 116 . A belt 122 is stretched over the upper pulley 118 and the lower pulley 120 . As shown in FIG. 4 , the lower pulley 120 is connected to a motor 126 through a gear box 124 . In this way, the drive of the belt 122 is performed by the motor 126 . As such a motor 126 , for example, a servo motor can be used.

如图2至图4所示，在天线杆112上以可沿垂直方向移动的方式设有基体128。从图2及图3可知，基体128与带122连接。进而，在基体128上安装有天线单元130。通过带122的驱动进行基体128的升降动作，由此，还进行天线单元130的升降动作。As shown in FIGS. 2 to 4 , a base body 128 is provided on the antenna rod 112 so as to be movable in the vertical direction. As can be seen from FIGS. 2 and 3 , the base body 128 is connected to the belt 122 . Furthermore, an antenna unit 130 is attached to the base body 128 . The raising and lowering operation of the base body 128 is performed by driving the belt 122 , thereby also performing the raising and lowering operation of the antenna unit 130 .

如图4最佳所示，天线单元130具备：天线140；支承天线140的天线支承机构150；调整天线140的仰角的仰角调整机构160；以及调整天线140的偏振波角的偏振波调整机构180。As best shown in FIG. 4 , the antenna unit 130 has: an antenna 140; an antenna support mechanism 150 supporting the antenna 140; an elevation angle adjustment mechanism 160 for adjusting the elevation angle of the antenna 140; and a polarization adjustment mechanism 180 for adjusting the polarization angle of the antenna 140 .

本实施方式的天线140是喇叭形天线。但是，本发明不限定于此，可以使用各种种类的天线。The antenna 140 of this embodiment is a horn antenna. However, the present invention is not limited thereto, and various types of antennas may be used.

如图4所示，天线支承机构150具备：前端安装有天线140的臂152；保持臂152的保持部件154；与保持部件154连结的轴156；以及设置在臂152上的水平仪158。As shown in FIG. 4 , the antenna support mechanism 150 includes: an arm 152 with the antenna 140 attached to its tip; a holding member 154 holding the arm 152 ; a shaft 156 connected to the holding member 154 ; and a level 158 provided on the arm 152 .

本实施方式中的臂152是呈直线状延伸的臂，并在垂直于臂152的轴的面上具有四边形的截面。但是，本发明不限定于此，臂也可以具有其他的形状。The arm 152 in this embodiment is an arm extending linearly, and has a quadrangular cross-section on a plane perpendicular to the axis of the arm 152 . However, the present invention is not limited thereto, and the arms may have other shapes.

为了能够由偏振波调整机构180对天线140的偏振波角进行调整，本实施方式的臂152匹配于天线140的接收波的中心轴来保持天线140。换言之，本实施方式的臂152以对准于天线140的接收波的中心轴的方式延伸。In order to adjust the polarization angle of the antenna 140 by the polarization adjustment mechanism 180 , the arm 152 of the present embodiment holds the antenna 140 in alignment with the central axis of the received wave of the antenna 140 . In other words, the arm 152 of the present embodiment extends so as to be aligned with the central axis of the received wave of the antenna 140 .

为了能够由偏振波调整机构180对天线140的偏振波角进行调整，本实施方式的保持部件154具备轴承构造来对臂152进行轴支承。因此，臂152能够绕自己的中心轴转动，从而可改变天线140的偏振波角。In order to enable adjustment of the polarization angle of the antenna 140 by the polarization adjustment mechanism 180 , the holding member 154 of the present embodiment includes a bearing structure to pivotally support the arm 152 . Therefore, the arm 152 can rotate around its central axis, thereby changing the polarization angle of the antenna 140 .

轴156呈圆柱状或圆筒状。轴156被插入在形成于基体128上的孔128a中，由此被基体128轴支承。由于轴156的一端被连结固定于保持部件154，因此，当轴156转动时，被保持部件154保持的臂152以保持部件154为中心旋转，由此，天线140的仰角变化。The shaft 156 has a cylindrical or cylindrical shape. The shaft 156 is inserted into the hole 128 a formed in the base body 128 , thereby being pivotally supported by the base body 128 . Since one end of the shaft 156 is connected and fixed to the holding member 154 , when the shaft 156 rotates, the arm 152 held by the holding member 154 rotates around the holding member 154 , thereby changing the elevation angle of the antenna 140 .

在本实施方式中，天线杆112和轴156未关联，以使基体128在天线杆112上的移动和轴156的转动是相互独立进行。In this embodiment, the antenna rod 112 and the shaft 156 are not associated, so that the movement of the base 128 on the antenna rod 112 and the rotation of the shaft 156 are independent of each other.

在本实施方式中，由于在臂152上设有水平仪158，所以能够客观地检测天线140是否被水平配置。如此，水平仪158作为用来检测天线140的仰角是否为0的水平检测部件起作用。但是，本发明不限定于此。例如，可以取代水平仪158，而使用各种角度传感器等来作为水平检测部件。另外，也可以对应于由水平检测部件检测出的状态，自动进行如以下说明的由仰角调整机构160进行的仰角调整。In this embodiment, since the level 158 is provided on the arm 152, it is possible to objectively detect whether or not the antenna 140 is arranged horizontally. In this way, the level 158 functions as level detection means for detecting whether or not the elevation angle of the antenna 140 is zero. However, the present invention is not limited thereto. For example, instead of the level 158, various angle sensors or the like may be used as the level detection means. In addition, the elevation angle adjustment by the elevation angle adjustment mechanism 160 as described below may be automatically performed in accordance with the state detected by the level detection means.

如图2及图4所示，本实施方式的仰角调整机构160是能够在独立于由升降机构110使天线单元130升降的状态下进行天线140的偏振波角的调整的机构。即，升降机构110的动作和仰角调整机构160的动作相互分别独立，并未关联。As shown in FIGS. 2 and 4 , the elevation angle adjustment mechanism 160 of this embodiment is a mechanism capable of adjusting the polarization angle of the antenna 140 independently of the elevation of the antenna unit 130 by the elevation mechanism 110 . That is, the operation of the elevating mechanism 110 and the operation of the elevation angle adjustment mechanism 160 are independent of each other and are not related.

本实施方式的仰角调整机构160被构成为在使天线140的仰角连续变化的同时对所述仰角进行调整。具体地说，仰角调整机构160通过以前述的轴156为轴使天线支承机构150转动，从而调整天线140的仰角。The elevation angle adjustment mechanism 160 of the present embodiment is configured to adjust the elevation angle of the antenna 140 while continuously changing the elevation angle. Specifically, the elevation angle adjustment mechanism 160 adjusts the elevation angle of the antenna 140 by rotating the antenna support mechanism 150 around the aforementioned shaft 156 .

如图4最佳所示，仰角调整机构160具备：仰角调整杆162；可滑动地被保持于仰角调整杆162的滑块164；连接固定于滑块164的进给螺母166；以及拧合在进给螺母166上的进给丝杠168。As best shown in Figure 4, the elevation angle adjustment mechanism 160 has: an elevation angle adjustment rod 162; a slide block 164 slidably retained on the elevation angle adjustment rod 162; a feed nut 166 connected and fixed on the slide block 164; Feed screw 168 on feed nut 166 .

仰角调整杆162的一端连接于天线支承机构150的轴156的另一端，通过仰角调整杆162的另一端的圆弧运动可使轴156转动。One end of the elevation angle adjustment rod 162 is connected to the other end of the shaft 156 of the antenna supporting mechanism 150 , and the shaft 156 can be rotated by the arc movement of the other end of the elevation angle adjustment rod 162 .

在仰角调整杆162的另一端形成有保持孔162a，保持孔162a具有竞技用跑道状的形状。滑块164以能够在该保持孔162a内滑动的方式被保持于仰角调整杆162。结果是，当滑块164沿垂直方向移动时，该滑块164在保持孔162a内滑动，同时可使仰角调整杆162的另一端进行圆弧运动。At the other end of the elevation adjustment rod 162, a holding hole 162a is formed, and the holding hole 162a has a racetrack-like shape. The slider 164 is held by the elevation angle adjustment lever 162 so as to be slidable in the holding hole 162a. As a result, when the slider 164 is moved in the vertical direction, the slider 164 slides in the holding hole 162a, and at the same time, the other end of the elevation angle adjustment rod 162 can be moved in a circular arc.

进给螺母166和进给丝杠168构成将旋转运动转换为直线运动的传递机构。详细地说，通过进给丝杠168的旋转，进给螺母166在进给丝杠168上被线性进给。即，进给丝杠168的旋转运动被转换为进给螺母166的直线运动。也可以取代进给螺母166和进给丝杠168的组合，而例如采用滚珠丝杠等其他的传递机构。The feed nut 166 and the feed screw 168 constitute a transmission mechanism that converts rotational motion into linear motion. In detail, the feed nut 166 is linearly fed on the feed screw 168 by the rotation of the feed screw 168 . That is, the rotational motion of the feed screw 168 is converted into the linear motion of the feed nut 166 . Instead of the combination of the feed nut 166 and the feed screw 168 , another transmission mechanism such as a ball screw may be used, for example.

在本实施方式中，如上所述进给螺母166被固定于滑块164，因此，在进给丝杠168的旋转的作用下，滑块164直线运动。进而，滑块164的直线运动被传递给仰角调整杆162，由此，仰角调整杆162旋转。该仰角调整杆的旋转被传递给天线支承机构150的轴156，由此，使天线支承机构150旋转，调整天线140的仰角。这样，本实施方式的仰角调整机构具备旋转-线性-旋转传递机构。但是，本发明不限定于此，只要可给予仰角调整杆162以旋转运动，也可以是其他机构。In the present embodiment, since the feed nut 166 is fixed to the slider 164 as described above, the slider 164 moves linearly by the rotation of the feed screw 168 . Furthermore, the linear motion of the slider 164 is transmitted to the elevation angle adjustment lever 162, whereby the elevation angle adjustment lever 162 rotates. The rotation of the elevation angle adjustment lever is transmitted to the shaft 156 of the antenna support mechanism 150 , whereby the antenna support mechanism 150 is rotated to adjust the elevation angle of the antenna 140 . In this way, the elevation angle adjustment mechanism of the present embodiment includes a rotation-linear-rotation transmission mechanism. However, the present invention is not limited thereto, and other mechanisms may be used as long as rotation motion can be imparted to the elevation angle adjustment lever 162 .

本实施方式中的仰角调整机构160还具备引导柱170以及经齿轮箱172连接于引导柱170的电动机174。作为电动机174，例如可使用伺服电动机。电动机174以及齿轮箱172作为使引导柱170旋转的旋转机构起作用。但是，本发明不限定于此，也可以采用其他的旋转机构。The elevation angle adjustment mechanism 160 in this embodiment further includes a guide column 170 and a motor 174 connected to the guide column 170 via a gear box 172 . As the motor 174, for example, a servo motor can be used. The motor 174 and the gear box 172 function as a rotation mechanism that rotates the guide column 170 . However, the present invention is not limited thereto, and other rotation mechanisms may also be employed.

参考图2，引导柱170以沿垂直方向延伸的方式被升降机构110的上侧部件114和下侧部件116保持为可转动。换言之，引导柱170与升降机构110的天线杆112平行延伸。Referring to FIG. 2 , the guide column 170 is held rotatably by the upper part 114 and the lower part 116 of the lift mechanism 110 in such a manner as to extend in a vertical direction. In other words, the guide column 170 extends parallel to the antenna rod 112 of the lifting mechanism 110 .

参考图4，本实施方式的引导柱170在与垂直方向正交的面内(水平面内)具有四边形的截面。同样，在本实施方式的进给丝杠168上形成有具有四边形的截面的滑块孔168a。但是，在水平面内，进给丝杠168的滑块孔168a的尺寸稍微大于引导柱170的尺寸。Referring to FIG. 4 , the guide column 170 of the present embodiment has a quadrangular cross-section in a plane (in a horizontal plane) perpendicular to the vertical direction. Similarly, a slider hole 168 a having a quadrangular cross section is formed in the feed screw 168 of the present embodiment. However, the size of the slider hole 168a of the feed screw 168 is slightly larger than the size of the guide post 170 in the horizontal plane.

引导柱170被插入在进给丝杠168的滑块孔168a中。根据上述的尺寸关系，进给丝杠168可以伴随着天线单元130的垂直移动而在引导柱170上滑动，另一方面，还可以伴随着引导柱170的转动而转动。The guide post 170 is inserted into the slider hole 168 a of the feed screw 168 . According to the above-mentioned dimensional relationship, the feed screw 168 can slide on the guide post 170 along with the vertical movement of the antenna unit 130 , and on the other hand, can also rotate along with the rotation of the guide post 170 .

本实施方式的引导柱170虽然具有四边形的截面，但本发明不限定于此。引导柱170只要是可将自己的旋转传递给进给丝杠168的形状，也可以具有其他形状。例如，引导柱170可以具有三角形、六边形、星形等截面。另外，滑块孔168a只要是进给丝杠168能够在引导柱170上滑动、另一方面进给丝杠168能够对应于引导柱170的旋转而旋转的形状，则也可以具有四边形以外的形状。而且，在引导柱170或滑块孔168a的形状是复杂的形状或角数多的多边形形状的情况下，为了使引导柱170和滑块孔168a之间的旋转力的传递顺畅，优选减小它们的间隙。Although the guide column 170 of this embodiment has a quadrangular cross section, the present invention is not limited thereto. The guide post 170 may have other shapes as long as it can transmit its own rotation to the feed screw 168 . For example, the guide post 170 may have a triangular, hexagonal, star-shaped, etc. section. In addition, the slider hole 168a may have a shape other than a quadrangular shape as long as the feed screw 168 can slide on the guide post 170 and the feed screw 168 can rotate corresponding to the rotation of the guide post 170. . Furthermore, when the shape of the guide post 170 or the slider hole 168a is a complex shape or a polygonal shape with many corners, it is preferable to reduce their gaps.

参考图3至图5，本实施方式的偏振波调整机构180被构成为在使天线140的偏振波角连续变化的同时对该偏振波角进行调整。Referring to FIGS. 3 to 5 , the polarization adjusting mechanism 180 of the present embodiment is configured to adjust the polarization angle of the antenna 140 while continuously changing the polarization angle.

具体地说，偏振波调整机构180具备偏振波调整杆182以及线性促动器184。偏振波调整杆182的一端被连接固定于臂152。另一方面，和仰角调整杆162与进给螺母166的连接同样，偏振波调整杆182的另一端是经滑块而与线性促动器184连接。因此，线性促动器184的直线运动在线性促动器184和偏振波调整杆182的连接部被转换为偏振波调整杆182的另一端的圆弧运动。进而，该偏振波调整杆182的另一端的圆弧运动作为转动运动被传递给臂184。由此，进行臂184的转动。如此，本实施方式的偏振波调整机构180通过在将直线运动转换为旋转运动的同时将该旋转运动传递给天线支承机构150，由此使天线支承机构150旋转而调整天线140的偏振波角。Specifically, the polarization adjustment mechanism 180 includes a polarization adjustment lever 182 and a linear actuator 184 . One end of the polarization adjusting rod 182 is connected and fixed to the arm 152 . On the other hand, the other end of the polarization adjustment rod 182 is connected to the linear actuator 184 via a slider, similarly to the connection between the elevation angle adjustment rod 162 and the feed nut 166 . Therefore, the linear motion of the linear actuator 184 is converted into the arc motion of the other end of the polarization adjusting rod 182 at the connecting portion of the linear actuator 184 and the polarization adjusting rod 182 . Furthermore, the arcuate motion of the other end of the polarization adjusting lever 182 is transmitted to the arm 184 as a rotational motion. Thereby, the rotation of the arm 184 is performed. In this manner, polarization adjusting mechanism 180 of this embodiment converts linear motion into rotational motion and transmits the rotational motion to antenna support mechanism 150 to rotate antenna support mechanism 150 to adjust the polarization angle of antenna 140 .

上述的偏振波调整机构180可以取代为其他构成。但是，根据本实施方式的偏振波调整机构180，可以实现天线升降机100的轻量化。The above-mentioned polarization adjustment mechanism 180 may be replaced with other configurations. However, according to the polarization adjustment mechanism 180 of this embodiment, the antenna lifter 100 can be reduced in weight.

上述的实施方式的天线升降机100是能够独立于天线单元130的向垂直方向的移动而对天线140进行双轴旋转控制的机构，因此，可以对各种被测定仪器进行各种测量。The antenna lifter 100 of the above-mentioned embodiment is a mechanism capable of controlling the two-axis rotation of the antenna 140 independently of the vertical movement of the antenna unit 130, and therefore can perform various measurements on various instruments to be measured.

以上，举出具体例子说明了本发明，但本发明不限定于此。As mentioned above, although specific examples were given and the present invention was described, the present invention is not limited thereto.

例如，在图1中，对应于天线单元130的高度H以及天线140的仰角θ，存在着天线升降机100和被测定仪器300的距离L与规定的测量距离不同的情况。为了应对该情况，也可以在电磁波测量系统设置对测量距离进行修正的距离修正机构。作为距离修正机构，可考虑各种结构，例如在天线升降机100的下侧部件116安装辊或车轮等，使天线升降机100本身形成为自走式机构，则系统不会太大型化，且天线升降机100的姿势平衡也不会打破，可以构成距离修正机构。For example, in FIG. 1 , depending on the height H of the antenna unit 130 and the elevation angle θ of the antenna 140 , the distance L between the antenna lifter 100 and the device under test 300 may differ from the predetermined measurement distance. In order to cope with this situation, a distance correction mechanism for correcting the measurement distance may be provided in the electromagnetic wave measurement system. As the distance correction mechanism, various structures can be considered. For example, rollers or wheels are installed on the lower part 116 of the antenna lifter 100, and the antenna lifter 100 itself is formed as a self-propelled mechanism, so that the system will not be too large, and the antenna lifter The posture balance of 100 will not be broken, and a distance correction mechanism can be formed.
