Detailed Description
For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, the antenna system according to a preferred embodiment of the present invention is used for receiving satellite signals, and the antenna system includes a receiving jig 1 and a plurality of frequency converters 2 mounted on the receiving jig 1, and can synchronously receive two or more satellite signals according to the number of the frequency converters 2.
In some embodiments, the receiving jig 1 includes a first guide mechanism 11, three second guide mechanisms 12, and three mounts 13 for mounting the frequency converter 2. The first guide mechanism 11 is provided with a first guide portion 111 provided along a first direction, and the second guide mechanism 12 is provided with a second guide portion 121 provided along a second direction, the first direction intersecting the second direction. The first guide mechanism 11 is correspondingly connected with the second guide mechanism 12, and the second guide mechanism 12 can move along the first guide part 111 in a first direction relative to the first guide mechanism 11 and move along the second guide part 121 in a second direction relative to the first guide mechanism 11, so that the position of the second guide mechanism 12 in the first direction and the second direction can be adjusted.
Each mounting seat 13 is respectively mounted on each second guide mechanism 12, and the steering position of the mounting seat 13 on the second guide mechanism 12 is adjustable. The frequency converter 2 on the mounting seat 13 receives different satellite signals respectively, and the position adjusting function of the clamp solves the problem that the signal field intensity is unstable when the synchronous receiving of the multi-satellite signals with small and medium angle differences is actually received, so that the receiving can be realized most intensively. The number of the second guide mechanisms 12 and the mounting seats 13 can be one or other than one, and when only one set of the second guide mechanisms 12 and the mounting seats 13 is used for mounting one frequency converter 2, correspondingly, the other frequency converter 2 can be fixedly mounted on the receiving clamp 1 or other supporting pieces, and only the orientation of the frequency converter 2 on the second guide mechanism 12 can be adjusted.
The multi-satellite receiving clamp 1 is particularly applied to synchronous reception of a plurality of satellite signals in a satellite broadcast television signal ground antenna receiving system, and when the satellite frequency converter 2 is used for receiving the multi-satellite signals, the clamp can adjust the installation angle of the frequency converter 2 product so as to realize optimal signal field intensity reception. The application characteristics of the method are more effectively highlighted in the small-angle multi-satellite signal receiving system, the signal receiving has higher field intensity receiving, the signal receiving quality is more superior, and the signal receiving is more flexible.
The clamp can comprehensively improve the signal transmission efficiency and the optimized receiving of the satellite signal field intensity. When multiple satellite signals with different latitudes are synchronously received, the problem that the receiving field intensity of the multiple satellite signals cannot be optimized in practical application due to multiple system factors such as different latitudes of geographic positions, mechanical structure process errors of antennas, sensitivity when multiple satellites are simultaneously received is solved through an omnidirectional fine adjustment fixture assembly angle and position mode, so that the receiving is more superior and accurate, the simultaneous optimized receiving of different multiple satellite signals is realized, the system performance is improved, and the stable and reliable signal receiving is realized.
