Abstract
The utility model relates to 13.7m millimeter-wave radio telescope antenna profile detecting equipment, which effectively solves the problems of difficult measurement, long measurement time and low accuracy. The technical scheme thereof is as follows: the detecting equipment comprises a radio telescope antenna and an antenna cover; the outer part of the radio telescope antenna is covered with the antenna cover; a guide rail which is arranged in the antenna cover is arranged along the inner wall of the antenna cover; the guide rail is provided with a moving camera; and the camera and a computer are connected by wireless signal communication. The 13.7m millimeter-wave radio telescope antenna profile detecting equipment has simple structure, convenient installation and use, high measurement accuracy and short time, can realize the measurement to any attitude of the antenna, and is an innovation of the detecting equipment.
Description
One, technical field
The utility model relates to checkout equipment, particularly a kind of 13.7 meters millimeter wave radio telescope antenna profile checkout equipments.
Two, background technology
For the radio telescope antenna, the antenna-reflected surface accuracy is antenna system major technology performance index, and generally requiring surface accuracy is 1/16～1/32 of antenna operation wavelength, and measuring accuracy will reach 1/3～1/5 of surface accuracy, operation wavelength is short more, and is just harsh more to measuring requirement.For 13.7 meters antennas, classical transit survey exists a lot of shortcomings, and is not high as measuring accuracy, can only measure antenna 90 degree attitudes, must centering before using, and when measuring to relatively strictness etc. of the requirement of temperature.And with the radio holography for antenna measurement, be very easily, it can be to any attitude measurement of antenna, and Measuring Time is short, measures more convenient.But, for 13.7 meters antennas,, measure difficulty owing to the existence of metal antenna cover and millimere-wave band lack the restriction of reasons such as far field millimeter-wave signal, measuring accuracy is low, so improvement and innovate imperative.
Three, utility model content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of 13.7 meters millimeter wave radio telescope antenna profile checkout equipments, can effectively solve and measure difficulty, Measuring Time is long, the problem that precision is low, the technical scheme of its solution is, include radio telescope antenna and antenna house, radio telescope antenna outside is covered with antenna house, and the guide rail (claiming slide rail again, as follows) that places in the antenna house is installed along the antenna house inwall, mobile camera is housed on the guide rail, and camera is connected by communicating wireless signals with computer.The utility model is simple in structure, and is easy to install, the measuring accuracy height, and the time is short, can realize the measurement to any attitude of antenna, is the innovation on the checkout equipment.
Four, description of drawings
Accompanying drawing is the utility model structural perspective.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by accompanying drawing, the utility model includes radio telescope antenna and antenna house, and radio telescope antenna 4 outsides are covered with antenna house 1, and the guide rail 2 that places in the antenna house is installed along the antenna house inwall, mobile camera 3 is housed on the guide rail, and camera and computer 5 are connected by communicating wireless signals.
In order to guarantee result of use, said radio telescope antenna 4 rotations are contained in bearing 6 tops, the primary reflection surface bore is 13.7m, focal length 5080mm, secondary face diameter 1085.1mm, primary reflection surface is by 24 of inner rings, 48 of outer rings amount to the hemisphere face body that 72 aluminum panel are formed, and have 8 to survey target on every aluminum panel of inner ring, there are 6 to survey target on the every aluminum panel in outer ring, have 480 adjustable survey targets on the primary reflection surface; Said antenna house 1 is that diameter is the cover body of 20.73m; Said guide rail 2 is arc or annular, subsequent corrosion be 10 meters (if during arc, arc length preferably the antenna house girth 1/4), this guide rail can be realized the manual control camera position, in the process of taking, can adopt the method for mobile camera rotating antenna to realize the multi-angle intersection measurement, instruct the rotation of adjusting antenna by the real-time shooting of wireless transmission card and remote control shutter device realization comparison film during measurement; Said camera 3 is the INCA3 of U.S. GSI company smart camera preferably, can be free to slide along guide rail (moving).
The utility model is owing to be an arc-shaped guide rail, in the process of taking, can change camera position by rotary antenna with along guide rail slip camera, in different angles with highly antenna is photographed, can satisfy the requirement of photography net type and measuring accuracy, the measuring accuracy height, measuring accuracy can reach 0.03mm, can satisfy the accuracy requirement of 13.7 meters antenna measurements; Measure convenient, flexiblely, be subjected to the restriction of space condition few, can measure in attitude arbitrarily antenna; Measuring speed is fast, short time can be gathered lot of data, and processing is to be handled automatically by computer software, improved the efficient of work greatly, efficiently solve the limitation in the traditional measurement and measure a difficult problem, demonstrated fully in antenna measurement advantages such as automaticity height, labour intensity are little, measuring accuracy height, also accumulated useful experience for photogrammetric antenna measurement in astronomical field from now on simultaneously, economic and social benefit is remarkable.
