Example 2:
a second aspect of the present invention provides a control method of an ultra-wideband miniaturized antenna, the control method being applied to any one of the ultra-wideband miniaturized antennas, the control method comprising the steps of:
s102, acquiring the number of antennas in a target area and the number of antennas in a target base station, and constructing a channel transmission path model diagram according to the number of antennas in the target area and the number of antennas in the target base station;
s104, acquiring geographical position information of each antenna in the current target area, and acquiring a transmission route model diagram of each antenna in the current target area according to the geographical position information and the channel transmission path model diagram;

and S108, adjusting the antenna data of the current target area according to the evaluation result to obtain an adjustment result, and transmitting the adjustment result to the remote control terminal.
It should be noted that, in this embodiment, in the process of using the antennas by the user, assuming that the base station is taken as an example and the user is taken as a receiving end, under the condition that the number of the antennas of the base station is certain, the channel transmission path model diagram is changed by changing the number of the antennas of the target area. The transmission route model diagram is equivalent to an MIMO system in a communication system, wherein the antenna data of the current target area is adjusted according to the evaluation result to obtain an adjustment result, the significance is to increase the number of the antennas of the target area to enhance the data transmission effect of the antennas, so that the data transmission effectiveness between the target area and the base station is realized, for example, the data transmission between a monitoring well and the base station is realized, the data transmission needs to be carried out for a long time by the monitoring well, and the effectiveness of the data transmission is easily unknown due to the influence of environmental factor data.
Further, in a preferred embodiment of the present invention, the method for obtaining the environmental factor data of the current target area through big data and obtaining the evaluation result according to the environmental factor data and the transmission route model map includes the following steps:
s202, a database is built, channel correlation of communication systems of all areas under all environmental factor data is obtained through a big data network, the channel correlation of the communication systems of all areas is input into the database, and a channel correlation database is generated;
s204, acquiring environmental factor data of a current target area through a big data network, inputting the environmental factor data of the current target area into the channel correlation database for environmental factor data matching, and obtaining one or more matching degrees;
s206, acquiring the environmental factor data with the matching degree larger than the preset matching degree, and acquiring the channel correlation corresponding to the environmental factor data according to the environmental factor data with the matching degree larger than the preset matching degree;
and S208, if the channel correlation is smaller than the preset channel correlation, marking the channel correlation as a data transmission node to be supplemented, otherwise marking the channel correlation as a normal data transmission node.
It should be noted that the environmental factor data may be a terrain factor, a weather factor, and the like, and the current environmental factor data is compared with the environmental factor data of each region stored in the database, and when the matching degree is greater than the preset matching degree, it is indicated that the environmental factor data in the region are highly similar, and then the channel correlation of the region is acquired. By the method, the channel correlation close to the environmental factor of the target area can be quickly found from the database, so that the number of the antennas of the target area (such as a monitoring well) is increased, the MIMO system formed between the base station and the antenna data of the target area is changed, and the transmission speed of the monitoring well in data transmission is increased. And both the data transmission node to be supplemented and the normal data transmission node are evaluation results.
Further, in a preferred embodiment of the present invention, the obtaining geographic position information of each antenna in the current target area, and obtaining a transmission route model map of each antenna in the current target area according to the geographic position information and the channel transmission path model map specifically include the following steps:
acquiring geographical position information of each antenna in a current target area and geographical position information of a target base station;
generating a first transmission route model diagram according to the geographical position information of each antenna in the current target area and the geographical position information of the target base station;
and constructing the first transmission route model diagrams one by one on the basis of the construction foundation of the channel transmission path model diagram to obtain the transmission route model diagrams of all antennas in the current target area.
It should be noted that the channel transmission path model diagram is a construction standard, for example, the number of antennas of the base station is 3, and the number of antennas of the target area is 3, that is, the channel transmission path model diagram will form a 3X3MIMO system, and so on. Thereby constructing a transmission route model diagram of each antenna in the current target area according to the construction reference.
In addition, the method can also comprise the following steps:
acquiring logic transmission habit data information of a target area, and acquiring target propagation delay data information according to the logic transmission habit data;
judging whether the target propagation delay data information is larger than preset delay data information or not;
if the target propagation delay data information is larger than preset delay data information, inputting the preset delay data information into the database for matching;
and acquiring the channel correlation with the matching degree larger than the preset matching degree information, acquiring the area with the channel correlation with the most frequent frequency as a final output result, and acquiring the number of the antennas which need to be increased or decreased in the target area according to the output result.
It should be noted that, in the case of the monitoring well, the channel correlation is an important factor influencing the data transmission rate. For example, in the process of monitoring a well, due to the relationship of the data information of the logic transmission habit, if data transmission needs to be completed within 5 minutes, data transmission needs to be completed within 10 minutes, that is, too high requirement is not required when the monitoring well transmits data, the data information of the target propagation delay is the delay of the propagation data, such as 5 minutes or 10 minutes in the above example, the channel correlation of the MIMO system under various environmental factors exists in the database, the region with the most frequent channel correlation is selected as the final output result, and the number of antennas which need to be increased or decreased in the target region is obtained according to the output result, so that the number of antennas which need to be increased or decreased is provided according to the data information of the logic transmission habit in the target region, so as to improve the communication system in the monitoring process, so as to adjust the speed of data transmission, so that the data transmission is more reasonable, thereby avoiding the technical problems of redundancy of the layout amount of the antennas in the monitoring process of the monitoring well and low data transmission efficiency in the monitoring process.
In addition, the method can also comprise the following steps:
acquiring an antenna layout node network of a current target area, and acquiring ip address information of each antenna layout node according to the antenna layout node network;
acquiring communication signals of antennas corresponding to ip address information of each antenna layout node, and judging that a remote antenna control terminal can receive the communication signals;
if the communication signal can be received, acquiring the time sequence interval times of the communication signal in a preset time, and judging whether the times are greater than the preset times;
and if the times are greater than the preset times, acquiring the geographical position information of the current antenna layout node, and transmitting the geographical position information of the current antenna layout node to a remote antenna control terminal in a preset mode.
It should be noted that, when the remote antenna control terminal cannot receive a part of antenna communication signals, it indicates that a fault state occurs in the transmission process or that the transmission process is affected by other influences, such as the influence of the fault state and the influence of the geographical position, further, by determining whether the number of signal time-series intervals in the communication process is greater than the preset number, and when the number of signal time-series intervals in the communication process is greater than the preset number, it indicates that the antenna system at this position has a certain transmission obstacle or a fault phenomenon, and by notifying the geographical position information of the current antenna layout node to the worker, the worker can quickly maintain or replace the position of the antenna system, so that the data transmission can maintain validity, and the success rate of data transmission can be improved.
In summary, the present invention describes a miniaturized and ultra-wideband Vivaldi antenna based on amplitude weighting and shaping, which is miniaturized within a specified size range on the premise of ensuring electrical performance, and obtains a larger antenna beam width while realizing the miniaturized design through lumped element amplitude weighting, thereby effectively improving the high-frequency lobe of an antenna pattern. The working bandwidth of the antenna is 5 octaves, and the antenna can realize the following functions within the wave beam coverage range: the gain in the beam of the azimuth +/-80 degrees and the pitching +/-50 degrees is better than-5 dBi, and the voltage standing wave ratio of the antenna is better than the index of 2.0.
According to the invention, the channel correlation of the current region is obtained according to the environmental factor information of the current target region, and the antenna data of the current target region is adjusted according to the channel correlation, so that the data transmission effectiveness is increased, the data transmission is reduced, and the method and the device are suitable for various application scenes. The invention can quickly find out the channel correlation close to the environmental factor of the target area from the database, thereby changing the antenna number of the target area (such as a monitoring well), further changing the MIMO system formed between the base station and the antenna data of the target area, and accelerating the transmission speed of the monitoring well in data transmission.
