Referring to Fig. 1-Fig. 4, measuring system according to embodiments of the present invention is described. As Figure 1-Figure 4, measuring system according to embodiments of the present invention comprises darkroom 100, holder tool 200 and surveying instrument (not shown).
Next describing darkroom 100 first in detail, as depicted in figs. 1 and 2, darkroom 100 comprises shielding case body 110, absorbing material layer 120 and multiple measurement antenna 130.
Absorbing material layer 120 is located on the inwall 111 of shielding case body 110. Multiple measurement antenna 130 is located on the inwall 111 of shielding case body 110, and each measurement antenna 130 is connected with the cable outside shielding case body 110.
Measuring system according to embodiments of the present invention, by absorbing material layer 120 and multiple measurement antenna 130 being arranged on the inwall 111 of shielding case body 110 and described cable is located at the outside of shielding case body 110, such that it is able to fully utilize the bearing function of shielding case body 110, it is not necessary to arrange tours antenna support in shielding case body 110. Thus it is possible not only to save the manufacturing cost of tours antenna support, and the error that the electromagnetism caused by tours antenna support blocks with radio communication measurement is caused by ELECTROMAGNETIC REFLECTION can be eliminated, improve precision and consistence that radio communication is measured, namely improve precision and the consistence of whole wireless communication measuring system.
And, by multiple measurement antenna 130 is arranged on the inwall 111 of shielding case body 110, the cable being connected with measurement antenna 130 all can be arranged on the outside of shielding case body 110, thus shielding case body 110 can mask completely by with the electromagnetic radiation measuring the cable generation that antenna 130 is connected, to avoid the internal measurement environment of electromagnetic interference shielding case body 110 that cable produces. That is, by cable being all arranged on the outside of shielding case body 110, such that it is able to eliminate the noisemaker that shielding case body 110 inside exists significantly, precision and the consistence of measurement thus can be improved.
In addition, owing to absorbing material layer 120 and multiple measurement antenna 130 are arranged on the inwall 111 of shielding case body 110, therefore the internal surface (radio frequency terminal surface) of absorbing material layer 120, the internal surface of measurement antenna 130 and the inwall 111 of shielding case body 110 spatially almost overlap. Thus it is possible not only to greatly reduce between the internal surface measuring antenna 130 and the inwall 111 of shielding case body 110 space taken, and it is centered around the ELECTROMAGNETIC REFLECTION that the absorbing material layer 120 measured around antenna 130 can eliminate the measurement of shielding case body 110 internal interference radio communication effectively, improve the precision measured and consistence further.
Therefore, measuring system according to embodiments of the present invention, darkroom 100 has low cost of manufacture, the advantage such as little, to improve measurement precision and consistence that takies space, and when ensureing measuring accuracy, can miniaturization, such as shielding case body can be the square bins of 1 meter for the length of side.
In an example of the present invention, such as, shielding case body 110 can arrange through hole in the position installing and measuring antenna 130, outside cable is connected through through hole with measurement antenna 130, the end that cable can be arranged on shielding case body 110 inwall with measurement antenna 130 is connected, joint can also be set in the end that measurement antenna 130 is arranged on shielding case body 110 inwall, after measuring antenna 130 and being installed in shielding case body 110, joint stretches out in shielding case body 110, thus be connected with outside cable, which thereby enhance the accessibility that cable connects.
Specifically, shielding case body 110 can be spherical. As shown in Figure 4, shielding case body 110 can be the cross section of column and shielding case body 110 can be circular or regular polygon. What it will be appreciated by those skilled in the art that is, shielding case body 110 has opening and the door for closing opening, as described in Figure 4, the left side of shielding case body 110 is provided with opening and the door 114 for opening and closing opening, thus is convenient to be placed into tested part in shielding case body 110 and takes out from shielding case body 110 is interior. Certainly, the present invention is not limited to this, and such as, the left end wall of shielding case body 110 can open and close, to form described opening and door. Door 114 is provided with locking gear 115, for lock door 114.
As shown in Figure 1, advantageously, the cross section of shielding case body 110 can be regular polygon. Thus can reduce manufacture difficulty and the manufacturing cost of shielding case body 110, it is to increase measuring accuracy, it is possible to reduce the quantity measuring antenna 130. And, owing to regular polygon has centre symmetry, so even multiple measurement antenna 130 is arranged in different edge, multiple measurement antenna 130 still can on same circle, it is possible to improve measuring accuracy.
The limit number of described regular polygon can be N, and N can be more than or equal to 3. Preferably, the limit number N of described regular polygon can be 12, and the quantity measuring antenna 130 can be 5. Thus when not affecting precision and the consistence that radio communication is measured, manufacture difficulty and the manufacturing cost in darkroom 100 can be reduced.
And, the absorptive character of absorbing material layer 120 significantly weaken along with the increase of hertzian wave input angle. For the shielding case body 110 that cross section is dodecagon, the hertzian wave maximum incident angle on any limit of shielding case body 110 is �� 15 degree, such that it is able to significantly promote the wave absorbing efficiency of absorbing material layer 120, and then can improve precision and the consistence of measurement.
As shown in Figure 1, in some embodiments of the invention, any two in multiple measurement antenna 130 are staggered each other in the radial direction of shielding case body 110, here radial direction staggers and should be interpreted broadly, as long as any two measurement antennas 130 are not opposite to each other, such as, measure antenna 130 and in no longer same plane, or antenna 130 can be measured in same plane, but any two measurement antennas 130 are just not right diametrically, will be described in more detail below.
Thus can fully utilize the symmetry of shielding case body 110, the quantity of the measurement antenna 130 needed for same measuring density is reduced by half, reduce further design cost and the manufacturing cost in darkroom 100, greatly widened the distance measured between antenna 130, it is to increase measuring accuracy. And, stagger each other owing to measuring antenna so that when meeting measuring accuracy, shielding case body can miniaturization, be convenient to mobile and carrying, it is to increase applicability.
Specifically, by any two in multiple measurement antenna 130 are staggered each other in the radial direction of shielding case body 110, it is possible not only to ensure that each contraposition position measuring antenna 130 is by absorbing material layer 120 all standing, the hertzian wave that measurement antenna 130 is sent fully is absorbed by absorbing material layer 120, and each limit, two ortho positions measuring antenna 130 can be made to exist without measurement antenna 130, the distance measured between antenna 130 can be improved when shielding case body the 110 of equal size, reduce the coupled interference between adjacent measurement antenna 130 and ELECTROMAGNETIC REFLECTION, the volume of shielding case body 110 can be reduced.
Such as, when two measurement antennas 130 are positioned at same plane, these two measurement antennas 130 stagger each other in the radial direction of shielding case body 110 and refer to that these two measurement antennas 130 are not in same radial direction. When two measurement antennas 130 are not when same plane, even if these two measurement antennas 130 are projected in same radial direction in same plane, these two measurement antennas 130 also stagger each other in the radial direction of shielding case body 110.
Advantageously, on adjacent two limit of shielding case body 110 different time install and measure antenna 130(and only in adjacent two limit of shielding case body 110 install and measure antenna 130), and relative two limit of shielding case body 110 is only installed a measurement antenna 130(i.e. in relative two limit of shielding case body 110 one installs and measures antenna 130). When measuring, owing to the antenna observed value of the measurement antenna 130 in contraposition direction is completely identical and only direction is contrary, therefore can by measuring unilateral communication index and carry out 180 degree of conversions, corresponding contraposition radio-frequency information can be obtained. As shown in Figure 1, being that the shielding case body 110 of dodecagon is example taking cross section, holder limit, tool 200 place is the 1st limit, by clockwise direction sequence, installs and measures antenna 130 respectively on the 2nd, 4,6,9 and 11 limits. Thus, it is possible to reduce the required quantity measuring antenna 130, and improve measuring accuracy.
Advantageously, shielding case body 110 can be limited with longitudinal center line, as mentioned above, it is necessary, shielding case body 110 can be column, multiple measurement antenna 130 can be arranged in the same plane orthogonal with the longitudinal center line of shielding case body 110.

Thus can improve measuring accuracy further. Advantageously, what the 2nd end 132 of multiple measurement antenna 130 can be positioned at by the center of circle of the longitudinal cenlerline of shielding case body 110 is circumferentially same. Thus can improve the measuring accuracy in darkroom 100 further. Preferably, the axis of any two the measurement antennas 130 in multiple measurement antenna 130 intersects each other.
As shown in Figure 1, in some examples of the present invention, the internal surface of absorbing material layer 120 can be toothed surfaces. Thus can improve the wave absorbing efficiency of absorbing material layer 120 further, the hertzian wave that measurement antenna 130 is sent fully is absorbed by absorbing material layer 120, effectively eliminate the ELECTROMAGNETIC REFLECTION that shielding case body 110 internal interference radio communication is measured, improve the precision measured and consistence further.
Advantageously, the tooth on the internal surface of absorbing material layer 120 can be the positive multi-prism taper tooth of discrete distribution. Thus can improve the wave absorbing efficiency of absorbing material layer 120 further, the hertzian wave that measurement antenna 130 is sent fully is absorbed by absorbing material layer 120, effectively eliminate the ELECTROMAGNETIC REFLECTION that shielding case body 110 internal interference radio communication is measured, improve the precision measured and consistence further.

Thus can make measurement antenna 130 fully Received signal strength, improve the precision measured and consistence further, and reduce owing to absorbing material humidity changes impact measuring result caused, make measurement more accurate.
Advantageously, the 2nd end 132 of multiple measurement antenna 130 extends beyond the internal surface predetermined distance of absorbing material layer 120. Measurement antenna 130 thus can be made to receive wireless signal more fully, improve the precision measured and consistence further.
