Fig. 1 shows a flowchart of an implementation of an antenna adjustment method provided in embodiment 1 of the present invention, which is detailed as follows:

the antenna adjusting method is applied to an antenna, the antenna is connected with electronic equipment, and the antenna adjusting method comprises the following steps:

s101, obtaining a target frequency, wherein the target frequency is determined by a target frequency channel selected by the electronic equipment.

In application, the antenna includes, but is not limited to, a communication antenna, a broadcasting antenna, and a television antenna, and the electronic device is a device connected to the antenna in a wired or wireless manner, and includes, but is not limited to, a routing device, a television device, a set-top box, a broadcasting device, and the like. In the embodiments of the present application, for convenience of explanation, the antenna in the present application is defined as a television antenna, the electronic device corresponds to a television device, and the television device may be provided with an interface connected to the television antenna, and the television antenna receives frequency channel information (digital signal code stream) sent by a television through the interface, decodes the information of the television frequency channel to obtain a desired operating frequency, and receives an electromagnetic wave signal at the operating frequency. The television antenna may also be wirelessly connected to a television device, and communicate with the television antenna by transmitting a signal, which is not limited thereto.

The target frequency is a working frequency corresponding to a frequency channel obtained by decoding received frequency channel information (namely, a digital signal code stream) sent by the television equipment by an antenna when a user controls the television equipment to change the frequency channel for playing a program. The target frequency channel refers to frequency channel information received by the television antenna during operation and transmitted by the television equipment, namely, the target frequency channel during operation of the television antenna, and can also be considered as a television channel selected by a user. Specifically, the frequency channels include all television channels that can be played by the television device, and the frequency ranges of all television channels that can be played by the television device and the operating frequencies corresponding to the television channels may be preset.

And S102, determining target medium parameters of the antenna according to the target frequency.

In application, the target medium parameters include, but are not limited to, the shape of a fountain formed by the liquid medium around the antenna device, such as the radius of the fountain covering the antenna, the height of the fountain, the flow rate of the liquid medium, and the like, when the television antenna operates, the television antenna adjusts the current medium parameters (such as the radius of the fountain) to the target medium parameters, and then changes the operating environment medium parameters of the television antenna, so that the television antenna can receive electromagnetic wave signals meeting the preset power requirement of the electronic device. Each working frequency of the television antenna can be pre-associated with a corresponding antenna medium parameter or an antenna radiation near-field area medium parameter and stored, so that after the television antenna determines the current working target frequency according to the received frequency channel information, the current medium parameter of the television antenna can be adjusted to the target medium parameter, the working environment medium parameter near the television antenna is changed, and the antenna radiation direction and the radiation gain are further adjusted.

S103, adjusting the current medium parameter of the antenna to the target medium parameter based on the adjustable medium.

In application, the adjustable medium includes, but is not limited to, a liquid medium, a gas medium, etc., for example, the ion concentration of the liquid medium is adjusted, a fountain formed by a tap water medium can be adjusted to a fountain formed by a salt water medium, or parameters of the gas medium near the television antenna are changed by releasing different gas media, etc., which is not limited in this respect. Illustratively, when the current television antenna is in operation, it scans electromagnetic wave signals in an air medium, and if the television device changes the current broadcast frequency channel to a target frequency channel, the television antenna queries the corresponding target frequency in table 1 according to the changed target frequency channel, determines a target medium parameter when the television antenna is in operation at the target frequency, and adjusts the medium parameter of the television antenna to the target medium parameter, for example, a fountain is formed around the antenna device by using a liquid medium to change the environment around the antenna device, so that the radiation gain of the television antenna is changed, and the power of the electromagnetic wave signals received by the antenna device meets the requirements, so as to adjust the radiation direction and the radiation gain of the antenna. It should be noted that the environment around the antenna may be a radiation near-field environment with only air as a medium, or may be a radiation near-field environment with a liquid medium and air as media, which is not limited herein. It will be appreciated that when a fountain is formed around the antenna device by means of a liquid medium, the shape of the fountain ejected by the liquid medium changes the medium environment around the antenna device, and that the above-mentioned medium parameters may thus be parameters of the shape of the fountain ejected by the liquid medium, such as the radius of the fountain, the height of the fountain, etc.

In this embodiment, the current required target frequency of the antenna and the corresponding target medium parameter are determined by obtaining frequency channel information sent by electronic equipment such as television equipment, so that the antenna adjusts the medium parameter to the corresponding target medium parameter, thereby changing the medium parameter near the antenna, and improving the radiation direction and radiation gain of the antenna working at the target frequency to obtain a good signal receiving effect.

In one embodiment, step S102 includes:

acquiring a pre-generated information table;

determining a target medium parameter corresponding to the target frequency according to the information table; and the information table stores the association relation between the preset frequency and the preset medium parameter.

In application, the information table is a table preset and stored in the antenna. Specifically, as shown in table 1 below:

frequency channel	Frequency range (Unit: MHz)	Frequency value (Unit: MHz)
			13	470-478	474
14	478-486	482
			...	...
68	950-958	954

Table 1 shows an example table of frequency ranges corresponding to respective television channels and operating frequencies corresponding to respective frequency channels. As shown in table 1, the first column refers to the codes (frequency channels) of the television channels played by the television apparatus, the frequency range of the second column of frequency channels, and the third column corresponds to the frequency value selected by the television antenna to receive the electromagnetic wave signal when the television antenna receives the frequency channel transmitted by the television apparatus. Illustratively, the frequency channel with the playing sequence number of 13 received by the television antenna is a target frequency channel, the corresponding frequency range is 470MHz-478MHz, and the television antenna acquires the corresponding operating frequency according to the frequency channel, that is, the target frequency (474 MHz). Through the preset incidence relation table of the preset frequency and the preset medium parameter, when the television antenna changes the frequency channel, the medium parameter can be adjusted to the corresponding target medium parameter, so that the medium parameter near the antenna is changed, the radiation gain and the radiation direction of the antenna are changed, and the required electromagnetic wave signal meeting the frequency requirement of the electronic equipment can be scanned.

Referring to fig. 2, in an embodiment, the information table is generated in advance by:

s201, sequentially adjusting the current medium parameters of the antenna to each preset medium parameter, and controlling the antenna to scan electromagnetic waves according to a preset frequency sequence under each preset medium parameter condition to obtain a power value of the electromagnetic waves at each preset frequency.

In application, the preset medium parameters are preset medium parameters, and different environment medium parameters can be obtained when the television antenna works corresponding to different preset medium parameters, so that different antenna radiation directions and radiation gains are obtained, and the television antenna can receive electromagnetic wave signals with a certain power value when working at the same or different working frequencies. The preset medium parameter may be a medium parameter that is regularly changed and is set by a user in advance, for example, the medium parameter is a liquid flow rate, and each preset medium parameter may be a difference between flow rates of adjacent liquid media by 0.1m/s, which is not limited herein. The preset frequency is determined according to frequency channel information sent by the television equipment. The preset frequency sequence is to scan electromagnetic waves from small to large or from large to small according to the corresponding preset frequency in the frequency channel, and is not limited. The above-mentioned antenna scans electromagnetic waves, which is prior art and will not be described in detail.

Illustratively, as with reference to table 1, the frequency channels correspond to frequency ranges of respective frequency channels of the television apparatus, and the predetermined frequency may be a median frequency value of the frequency ranges in each of the frequency channels. When the television equipment plays the channel programs, each channel program played by the television equipment corresponds to a corresponding frequency channel, that is, the television antenna needs to work in a frequency range corresponding to the frequency channel. For example, in the frequency channel labeled 13, the highest frequency is 478MHz, the lowest frequency is 470MHz, and the middle frequency is 474MHz, in this embodiment, the middle frequency of the frequency channel is defined as representing the corresponding frequency channel, if the medium parameter of the environment where the television antenna is located is a1, under this medium parameter, the television antenna scans the electromagnetic waves according to the preset frequency sequence (the frequencies from 474MHz to 954MHz in table 1 change from small to large) and obtains the corresponding power value, then changes the medium parameter of the environment where the television antenna is located to a2, and scans the electromagnetic waves again according to the preset frequency sequence and obtains the corresponding power value.

S202, respectively obtaining preset medium parameters and preset frequencies corresponding to the power values exceeding the preset threshold value, and establishing an association relation between the preset frequencies and the preset medium parameters.

And S203, generating an information table according to the incidence relation.

In application, the preset threshold is a preset power value, and it is determined whether the power value of the electromagnetic wave signal obtained by the television antenna under the corresponding medium parameter and the corresponding frequency is greater than the preset threshold, so that the television device can normally play the program corresponding to the frequency channel. And if the power value of the acquired electromagnetic wave signal of the television antenna is greater than a preset threshold value under the corresponding preset medium parameter and the corresponding preset frequency, establishing and storing the incidence relation between the current preset frequency and the current preset medium parameter. The above-mentioned association relation can be correspondingly stored in the form of table in the interior of television antenna. Illustratively, as the frequency channel labeled 13 in table 1, the frequency range corresponding to the 13 frequency channel of the television device is 470MHz-478MHz, the corresponding target frequency is 474MHz, the power value of the electromagnetic wave signal obtained by scanning the television antenna at 474MHz is greater than the preset threshold value under the current preset medium parameter condition, it is determined that the electromagnetic wave signal meeting the power requirement of the electronic device can be received, then the association relationship between the preset frequency and the preset medium parameter is established, and then all the association relationships are established into the information table and stored.

In this embodiment, by configuring each medium parameter condition when the antenna works in advance, the antenna sequentially works under the corresponding medium parameter condition, scans electromagnetic wave signals with preset frequencies in different frequency channels, and when the power value of the scanned electromagnetic wave signals is greater than a preset threshold, establishes and stores an information table containing the association relationship between the preset frequencies and the current preset medium parameters, so that when the antenna receives a frequency channel replaced by television equipment, the radiation direction and the radiation gain of the antenna can be flexibly adjusted according to the information table, thereby obtaining a good signal receiving effect.

Referring to fig. 3, in an embodiment, after step S203, the method further includes:

s301, judging whether the preset frequency is associated with a plurality of preset medium parameters.

S302, if the preset frequency is associated with the preset medium parameters, the power value of the electromagnetic wave obtained by the antenna under each preset medium parameter and the preset frequency is correspondingly obtained.

In application, when the television antenna at the same preset frequency works in different medium environments with preset medium parameters, and the power value of each obtained electromagnetic wave is greater than a preset threshold, the working frequency respectively establishes an association relationship with the plurality of preset medium parameters, that is, the preset frequency and the plurality of preset medium parameters have an association relationship.

Exemplarily, assuming that the medium parameters represent 10 different medium parameter conditions for the television antenna to work by 1 to 10, the television antenna scans the electromagnetic wave signal by 474MHz, the power value of the scanned electromagnetic wave signal is greater than the preset threshold value when the medium parameter condition is 1, the power value of the obtained electromagnetic wave signal is also greater than the preset threshold value when the medium parameter condition is 2, and the power values of the scanned electromagnetic wave signals are not greater than the preset threshold value under other medium parameter conditions, at this time, the information table may have an association relationship established between the preset frequency 474MHz and the medium parameter condition 1, and may also have an association relationship established between the preset frequency 474MHz and the medium parameter condition 2.

And S303, determining the optimal associated medium parameter according to the power value of the electromagnetic wave obtained by the antenna under each preset medium parameter and the preset frequency.

S304, keeping the association relationship between the preset frequency and the optimal associated medium parameter in the information table, and deleting the association relationship between the preset frequency and other preset medium parameters.

In application, if an association relationship exists between one preset frequency and a plurality of preset medium parameters in an information table, the power value of the electromagnetic wave obtained by the television antenna under each preset medium parameter and preset frequency is obtained, the medium parameter corresponding to the maximum power value is determined as the optimal associated medium parameter, the association relationship between the preset frequency and the optimal associated medium parameter is stored in the information table, and the association relationship between the preset frequency and other preset medium parameters in the information table is deleted.

In other applications, if the medium parameters represent 10 different medium parameter conditions for the television antenna to work by 1-10, and the number of 1-10 represents the difficulty of using the corresponding medium parameter, the difficulty of adjusting the current medium parameter to the target medium parameter corresponding to the medium parameter with the larger number is increased, or the power consumption of the corresponding television antenna is higher by using the medium parameter with the larger number. For example, if the medium parameter 1 represents that the flow rate of the liquid medium is 1m/s, the power consumption when the television antenna controls the flow rate of the liquid medium to be 1m/s is P1, the medium parameter 2 represents that the flow rate of the liquid medium is 2m/s, the power consumption when the television antenna controls the flow rate of the liquid medium to be 2m/s is P2, and the power consumption P2 is greater than the power consumption P1. When the television antenna scans electromagnetic wave signals at the working frequency of 474MHz, under the condition that the medium parameter condition is 1 and the medium parameter condition is 2, if the power values of the obtained electromagnetic waves meet the requirements, the medium parameter with lower power consumption is selected as the optimal medium parameter, and an association relationship is established, which is not limited.

In this embodiment, the information table is updated by comparing a plurality of power values scanned by the antenna under the association relationship established in the information table, and selecting and storing the association relationship between the preset frequency and the optimal associated medium parameter, so that the antenna can be adjusted to the optimal antenna radiation direction and radiation gain according to the target frequency, and a good signal receiving effect is obtained.

In other embodiments, after step S202, that is, after the preset medium parameters and the preset frequency corresponding to each power value exceeding the preset threshold are respectively obtained and the association relationship between the preset frequency and the preset medium parameters is established, steps S301 to S303 may be executed, and after step S303, the following step is executed: and establishing an incidence relation between a preset frequency and an optimal incidence medium parameter, and generating an information table according to the incidence relation between the preset frequency and the optimal incidence medium parameter. Namely, in the process of establishing the information table, the information table of the association relationship between the preset frequency and the optimal associated medium parameter is directly generated, and the subsequent process of updating the information table is omitted, which is not limited.

In one embodiment, the antenna comprises a first radiation piece, the first radiation piece is provided with a hollow channel, the bottom end of the first radiation piece is connected with an electronic valve, a shielding piece is connected above the first radiation piece, and the preset medium parameter comprises the flow rate of the liquid medium flowing through the first radiation piece; step S201 includes:

and sending a first control signal to the electronic valve, wherein the electronic valve is used for controlling the flow rate of the liquid medium in the first radiation piece according to the first control signal, so that the liquid medium is blocked and diffused to a corresponding shape by the shielding piece after being sprayed out.

In application, the liquid medium includes liquid media of different media such as tap water and saline water, and the preset medium parameter includes a flow rate of the liquid medium flowing through the first radiation member. The liquid medium is water, flows through the first radiation piece at the flow speed of 1m/s, and is blocked by the blocking piece at the upper end of the first radiation piece, so that the radius and the height of the sprayed water change the medium parameter condition of the near field area of the television antenna, and the distance of the television antenna for radiating electromagnetic wave signals is changed, thereby changing the gain of the television antenna for scanning electromagnetic waves.

In application, the preset flow rate is a flow rate preset by a user, and the pressure of the electronic valve on the liquid medium can be changed by sending a first control signal to the electronic valve, so that the flow rate of the liquid medium is adjusted to the preset flow rate. The antenna equipment can adjust the flow velocity of the liquid medium flowing through the first radiation piece to each preset flow velocity, and control the antenna to scan the electromagnetic waves according to the preset frequency sequence under each preset flow velocity condition, so as to obtain the power value of the electromagnetic waves under each preset frequency. Illustratively, the television antenna controls the flow rate of the liquid medium to be 1m/s in advance through the electronic valve, then scans the electromagnetic waves according to the preset frequencies (474MHz, 482MHz,.. times.954 MHz) in sequence of table 1 to obtain the power values of the electromagnetic waves at the preset frequencies, then adjusts the flow rate of the liquid medium to be 2m/s, and scans the electromagnetic waves according to the preset frequencies in sequence of table 1 to obtain the power values of the electromagnetic waves at the preset frequencies.

In operation, a liquid medium 600 is injected towards the inlet, the liquid medium 600 passes through the hollow channel of the first radiant element 200 and is ejected from the outlet to the screen 400, and the screen 400 drains the liquid medium 600, thereby forming a fountain.

In this embodiment, the water level depth of the submerged antenna is changed by independently adjusting the amount of the liquid medium flowing in and out, so that the submerged antenna is adjusted to the preset water level depth, the power value of the antenna for receiving electromagnetic wave signals at each preset frequency is obtained, and the information table of the association relationship between the preset frequency and the preset medium parameter is established, so that when the antenna works in the condition of receiving different frequency channels of the electronic device, the radiation direction and the radiation gain of the antenna can be flexibly adjusted, and a good signal receiving effect is obtained.

In one embodiment, the antenna further comprises at least two second radiating elements, the second radiating elements being disposed around the first radiating elements; the preset medium parameters also comprise the water level depth of the liquid medium in the water storage container submerging the first radiation piece and the second radiation piece; step S201 includes:

and traversing the preset flow rate of the liquid medium flowing through the first radiation piece and the preset water level depth of the liquid medium in the water storage container for submerging the first radiation piece and the second radiation piece to obtain a preset medium parameter combination.

Controlling the working number of the second radiation pieces and the relative positions of the working second radiation pieces and the first radiation pieces;

sequentially adjusting the working number of the second radiation pieces to each preset working number and adjusting the preset relative positions of the working second radiation pieces and the first radiation to obtain all antenna working combinations;

under each antenna working combination, the current medium parameters of the antenna working combination are sequentially adjusted to each preset medium parameter, the antenna is controlled to scan electromagnetic waves according to a preset frequency sequence under each preset medium parameter combination condition, and the power value of the electromagnetic waves at each preset frequency is obtained.

In application, the preset flow rate of the liquid medium flowing through the first radiation piece and the preset water level depth of the liquid medium in the water storage container submerging the first radiation piece and the second radiation piece can be simultaneously combined and changed to adjust the medium parameters of the antenna.

In a specific application, the liquid medium is water, when the television antenna (the first radiation piece and the second radiation piece) is connected with the television equipment for the first time, the television antenna is initialized, a chip program of the signal processing chip is set to run in initialization time, if the initialization time is 3min, the signal processing chip divides the water level and the water speed into 256 values respectively, the water level is adjusted in sequence, the water pressure of the electronic valve is adjusted to enable the water to have different flow rates and the working quantity of the second radiation piece, and electromagnetic waves are scanned according to a preset frequency sequence. If the preset flow rate is X1m/s, the water level is X2mm, the installation positions of different second radiation elements Y are different, therefore, when the different second radiation elements work, the different second radiation elements and the first radiation elements form different working combination forms to form different states, and different radiation directions and radiation gains are generated. If the power value of the electromagnetic signal acquired by the antenna meets the requirement, and then the association relation between the target frequency channel and the state a is established, in the state a1, the X1 is 1m/s, the X2 is 50mm, the Y is Y1, and the state a is recorded under a certain target frequency. Then, under the condition that X1 and X2 are not changed, the result state a of the change of the working second radiation piece Y is changed in sequence, the power value of the electromagnetic wave signal meeting the requirement of the phase antenna under a certain target frequency is obtained, and the incidence relation between the preset frequency and the preset medium parameter under the working combination state of the antenna is established.

In this embodiment, the radiation direction and the radiation gain of the antenna are changed by comprehensively adjusting the number of the second radiation members and the relative position combination of the second radiation members and the first radiation members, and the variation of the preset medium parameters during the operation of the antenna is increased by combining the preset flow rate of the liquid medium flowing through the first radiation members under each combination and the preset water level depth of the liquid medium in the water storage container submerging the first radiation members and the second radiation members, so that the power value of the electromagnetic wave signal meeting the requirements under a plurality of different medium parameters can be obtained by the antenna under the same target frequency, and the optimal power value can be obtained according to a plurality of power values, so that the radiation direction and the radiation gain of the antenna can be flexibly adjusted when the antenna operates under the requirement of the target frequency, thereby obtaining a good signal receiving effect.

In an embodiment, the adjusting method further includes updating an information table at a timing, and the updating the information table at the timing includes:

when a preset condition is met, acquiring a check preset frequency;

determining a relevant preset medium parameter according to the check preset frequency;

adjusting the current medium parameter of the antenna to the associated preset medium parameter, and scanning an electromagnetic wave signal under a check preset frequency to obtain a check power value;

judging whether the checking power value meets a checking condition or not;

and if the checking power value does not meet the checking condition, reestablishing the association relation between each target preset frequency and the corresponding preset medium parameter.

In an application, the preset condition may be an idle time when the antenna is not in operation, and/or a time reaching the verification time (a time reaching a preset time period from the last verification), which is not limited herein. The check power value is a power value obtained by the television antenna scanning the electromagnetic signal under the association preset medium parameter and the check preset frequency, and is actually a power value obtained by the television antenna scanning the electromagnetic signal under the medium parameter and the preset frequency establishing the association relation under the current check time node. The preset frequency stored in the information table can be used as the verification preset frequency, and the verification preset medium parameter corresponding to the verification preset frequency is determined according to the association relation. If the association relationship is established between the medium parameter a1 and the target frequency channel a, when the association relationship is obtained, the power value of the television antenna at the preset frequency in the medium parameter a1 and the target frequency channel a is obtained, and when verification is performed later, the power value of the scanned electromagnetic wave signal is obtained as the verification power value by the television antenna at the preset frequency in the medium parameter a1 and the target frequency channel a again. If the checking power value is not consistent with the previous power value, the checking power value is judged not to meet the checking condition, and the working position of the television antenna can be determined to be changed, so that the association relation between each target preset frequency and the corresponding preset medium parameter needs to be reestablished and stored.

In other applications, when the check preset frequency in the information table is selected, the optimal associated medium parameter corresponding to the check preset frequency can be selected as the check preset medium parameter, so that the television antenna scans the power of the electromagnetic wave signal at regular time under the check preset frequency and the check preset medium parameter.

In this embodiment, by operating the antenna at the associated preset medium parameter and the check preset frequency, specifically, the antenna is operated at any target preset frequency and preset medium parameter for establishing an association relationship, a power value of an electromagnetic wave signal scanned by the antenna at a current check time node is used as a check power value, and is compared with a power value stored when the association relationship is established, so as to determine whether a working environment of the antenna changes, and after determining that the working environment changes, the association relationship between the target preset frequency and the corresponding preset medium parameter is updated in time.
