Disclosure of Invention
The invention aims to provide a signal automatic measuring and switching device which has the advantages of simple structure, reasonable design, high intelligent degree, convenience in use and the like.
The technical scheme of the invention is realized as follows: a signal automatic measurement and switching device comprises at least 4 main feeder lines, a signal switching module, a measurement switching module and a main control module; one end of the main feeder line is electrically connected with one output port of the signal switching module, and the other end of the main feeder line is used for being electrically connected with the antenna radiation unit;
each main feeder line is also provided with a signal monitor, and each signal monitor is electrically connected with the measurement switching module through a measurement feeder line; the measurement switching module is also electrically connected with the main control module, and is controlled by the main control module to select one path of measurement feeder line to be communicated with the main control module;
the main control module is also electrically connected with the signal switching module, and the main control module controls the signal switching module and the measurement switching module to act according to the signal intensity value of the measurement feeder line communicated with the main control module.
The input port of the signal switching module of the automatic signal measuring and switching device is electrically connected with the radio frequency signal receiving and transmitting port of the terminal equipment, and each main feeder is electrically connected with the antenna radiation units distributed on the periphery of the luneberg lens. Because the electromagnetic waves of each antenna radiation unit have different beam orientations after passing through the luneberg lens, and the signal strengths of the different beam orientations are different, the signal strength of the antenna radiation unit can reflect the signal reception strength of the terminal device, and the stronger the signal strength indicates that the beam orientation of the antenna radiation unit can meet the communication requirement of the terminal device more at the base station where the antenna radiation unit is located. When the main control module switches, the main control module gates another main feeder line to work through the signal switching module, and simultaneously, the main control module also gates a corresponding measuring feeder line through the measuring switching module to detect the signal intensity of the main feeder line. When the main control module adopts a bad removing strategy, when the signal intensity of the current main feeder is lower than a preset threshold value, the main control module controls the other main feeder to be gated to work through the signal switching module, and simultaneously, the corresponding measuring feeder is gated to detect the signal intensity of the main feeder, if the signal intensity of the switched main feeder is higher than the preset threshold value, the main control module does not control the main feeder to be switched and keeps working by the main feeder, if the signal intensity of the switched main feeder is still lower than the preset threshold value, the main control module continues to control and switch to the next main feeder until the main feeder with the signal intensity higher than the preset threshold value is found, and if the signal intensities of all the main feeders are lower than the preset threshold value, the main feeder with the strongest signal intensity is switched to. When the main control module adopts a preference strategy, the main control module can switch to other main feeders at a specific time to find other main feeders with higher signal strength, and once such main feeders are found, the main control module controls to switch to work by the main feeder. The specific timing may be a preset time interval or a preset control value of the signal strength. The main control module enables the terminal equipment to eliminate co-channel interference through an inferior strategy, a preferred strategy or other strategies, so that the terminal equipment is in a good communication environment as far as possible.
It is to be noted here that the present automatic signal measurement and handover arrangement is equally applicable in a base station. When the antenna is used, the input port of the signal switching module is electrically connected with a base station transceiver in a base station, and in the application process, as in the application of terminal equipment, when the signal intensity of a certain antenna radiation unit is lower than a preset threshold value or the signal intensity of other antenna radiation units is found to be stronger, the antenna needs to be switched to work by other more proper antenna radiation units; as is known, the positions of tribes on the grassland where the tribes live may change at intervals, so that when the base station on the wide grassland is provided with the automatic signal measuring and switching device, the base station can switch the antenna radiation unit to be operated through the automatic signal measuring and switching device after the living positions of the tribes change, and thus the next tribes around the base station can be found, and the base station resources can be fully applied.

Further, the signal monitors are preferably arranged at the same position on the main feeder where they are located. That is, the lengths of the main feeder lines from the signal monitors to the output ports of the corresponding signal switching modules on each main feeder line are the same. Therefore, the problem of inaccurate detection signals caused by different detection positions can be avoided.
Furthermore, for the design of the product to be more flexible, the input port of the signal switching module is electrically connected with a transceiving module or the output port of the signal switching module is electrically connected with a transceiving module between one end of each main feeder line and the output port of the signal switching module. The receiving and transmitting module is a signal amplifier, and the strength of the signal can be amplified through the receiving and transmitting module when in use, so that the automatic signal measuring and switching device has wider application range.
