Description
Technical Field
The invention relates to the technical field of communication, in particular to an intelligent multi-beam luneberg lens antenna.
Background
The existing multi-beam mobile communication antenna is provided with a plurality of feed sources, the feed sources are switched to work in sequence during work, one working feed source can form a beam, the area covered by the beam is the area of normal communication, but a coverage blind area exists between 2 adjacent beam. If there is a device in the coverage hole that needs to communicate, the existing multi-beam mobile communication antenna is not electronically adjustable to allow the adjusted beam pattern to cover the device, and thus the existing antenna is generally not able to do so when the above situation is encountered. Based on the defects of the existing antenna in use, it is urgently needed to design an antenna capable of combining adjacent beams to meet the use requirement.
Disclosure of Invention
The invention aims to provide an intelligent multi-beam Luneberg lens antenna which has the advantages of simple structure, scientific design and convenient use, and can control 2 adjacent beams generated by the antenna to be combined so as to change the signal coverage range.
The technical scheme of the invention is realized as follows: an intelligent multi-beam Luneberg lens antenna comprises a switch combining way switching module, a Luneberg lens and at least 3 feed sources, wherein the at least 3 feed sources are arranged on the periphery of the Luneberg lens, and the signal receiving and transmitting directions of the feed sources are arranged towards the Luneberg lens; the switch combining switching module comprises a first switch module, a second switch module and at least 3 third switch modules; the first switch module and the second switch module are respectively provided with 1 input end and at least 3 output ends, the respective input ends of the first switch module and the second switch module are used for inputting radio frequency signals, and the first switch module and the second switch module are modules which only control the conduction of the input ends of the first switch module and the second switch module with one output end of the first switch module at a time; the third switch module is provided with 2 input ends and 1 output end, and the third switch module is a module which only controls one input end to be conducted with the output end of the third switch module at a time; a third switch module corresponds to 1 output end of the first switch module and 1 output end of the second switch module, one input end of the third switch module is electrically connected with 1 output end of the first switch module, and the other input end of the third switch module is electrically connected with 1 output end of the second switch module; the output end of the third switch module is electrically connected with the feed source through a feed source port.
When the scheme is used, the respective input ends of the first switch module and the second switch module of the switch combining switching module are connected with radio frequency signals. When the switch is applied, the first switch module, the second switch module and each third switch module of the switch on-off switching module can be set. The scheme has the following two conditions in the application process:
the first condition is the condition that the wave beams generated by adjacent 2 feed sources do not need to be combined, in this condition, the switch combination switching module group only needs to control the first switch module to make the output end of the first switch module switch in sequence for signal output, and the output end of each third switch module is only connected with the input end of the third switch module connected with the first switch module.
The second situation is the situation that beams generated by adjacent 2 feeds need to be combined, and the reason for this situation is that there is a device needing signal coverage between the adjacent 2 beams in the application process, in order to cover the device, under the condition that no feed is added, beams on both sides of this device need to be combined, here, the 2 beams needing to be combined are respectively called as a first beam and a second beam, the feed generating the first beam is called as a first feed, and the feed generating the second beam is called as a second feed; when the method is applied, the setting of the first switch module is as follows: the first switch module controls the output ends of the first switch module to be sequentially switched to be used for signal output, and the first switch module can directly skip the output end which controls the second feed source to work in the process of controlling the output ends of the first switch module to be sequentially switched to output signals; the settings for the second switch module are: only the input end of the second feed source is connected with the output end which controls the second feed source to work; the settings for the third switch module are: the output end of the third switch module for controlling the second feed source to work is connected with the input end connected with the second switch module, and the output ends of other third switch modules are connected with the input end connected with the first switch module; by setting the first switch module, the second switch module and each third switch module, the first beam and the second beam are presented simultaneously in the working process of the scheme, so that the first beam and the second beam can interact and combine, and the coverage range is changed after the beams are combined, thereby realizing the coverage of the equipment between the adjacent beams. This is the case of combining a group of adjacent beams, for example, when two or more groups of adjacent beams need to be combined in application, the present solution can also be obtained by reasonably setting the first switch module, the second switch module, and each third switch module.
Furthermore, the scheme also comprises a combiner, wherein the combiner is provided with 1 input end and 2 output ends, the input end of the combiner is connected to the signal transceiver when in use, one output end of the combiner is electrically connected with the input end of the first switch module, and the other output end of the combiner is electrically connected with the input end of the second switch module. When the design is used, only one signal transceiver can be adopted, and the application cost can be reduced. Certainly, when the dual-mode radio frequency filter is used, two coherent radio frequency signals can be directly used, the input end of the first switch module and the input end of the second switch module are respectively and electrically connected with one radio frequency signal, so that wave beams in different shapes can be obtained when the dual-mode radio frequency filter is applied, and the flexibility in use is greatly improved.
Furthermore, the length of a conducting circuit path between the input end and each output end in the first switch module is the same as the length of a conducting circuit path between the input end and each output end in the second switch module; the length of a conducting circuit path between each output end of the first switch module and the input end of the third switch module is the same as the length of a conducting circuit path between each output end of the second switch module and the input end of the third switch module. Due to the design, the beam size difference caused by the fact that the lengths of lines transmitted to the feed sources are different is avoided.
Further, the switch combining switching module further comprises a main control module, and the first switch module, the second switch module and each third switch module are electrically connected with the main control module.
Furthermore, the master control module is electrically connected with an RS485 port. Therefore, when the intelligent control system is used, the microprocessor in the main control module communicates with the outside through the 485 level conversion chip, and the communication protocol adopts ASCii codes.
Furthermore, the switch combining and switching module further comprises a power supply, and the first switch module, the second switch module, the main control module and each third switch module are electrically connected with the power supply. The power supply generally comprises a switching power supply module and a low-dropout linear voltage-stabilized power supply module, wherein the switching power supply module can be connected with an external 8-24V direct-current power supply through the input end of the switching power supply module, the output end of the switching power supply module is electrically connected with the input end of the low-dropout linear voltage-stabilized power supply module, and the output end of the low-dropout linear voltage-stabilized power supply module is electrically connected with a first switching module, a second switching module, a main control module and each third switching module.
Furthermore, the number of the feeds is N × N, N is greater than or equal to 2, the number of the third switch modules of the switch combining and switching module is the same as the number of the feeds correspondingly, and the first switch module and the second switch module are respectively provided with output ends with the same number as the feeds; the feed sources are arranged in a straight line or in an N x N array.
