The antenna adjusting method provided by the embodiment of the application can be applied to antenna equipment such as communication antennas, broadcast antennas, television antennas and the like, and the embodiment of the application does not limit the specific type of the antenna equipment.

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:

an antenna adjusting method is applied to an antenna, the antenna is connected with an electronic device, 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 can convert a guided wave propagating on a transmission line into an electromagnetic wave propagating in space or vice versa, and can also be used in conjunction with a radio device for transmitting or receiving electromagnetic waves. In engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like, all of which transmit information by using electromagnetic waves, work by depending on antennas. In this embodiment of the application, for convenience of explanation, the antenna may be a television antenna, and is configured to be connected 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 target frequency, and receives an electromagnetic wave signal at the target 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.

And S102, determining the target working state of the antenna according to the target frequency.

In application, the target operating state includes, but is not limited to, the number of operating television antennas, antennas operating in different positions in combination, and the like, which is not limited in this respect. Each preset frequency of the television antenna can be associated with the working state of the corresponding television antenna in advance and stored, so that the current working state of the television antenna can be adjusted to the target working state after the television antenna determines the current working target frequency according to the received frequency channel information.

In a specific application, the antenna is configured to include a plurality of sub-antennas, and the operating state of the antenna includes a first operating state a, a second operating state B, and a third operating state C, where the first operating state a may be that only one sub-antenna operates, the second operating state B may be that two sub-antennas operate simultaneously, and the like, and the third operating state C is a current operating state. The television antenna operates in the current operating state C, and then the user adjusts the target frequency channel of the television device, so that the television antenna receives a corresponding target frequency, for example, an operating frequency of 474MHz, to operate, and then determines that the target operating state corresponding to the antenna is the second operating state B at the current operating frequency of 474MHz, that is, the current operating state C of the antenna is adjusted to the second operating state B, and at the same time, the two sub-antennas operate.

In this embodiment, the current required operating frequency of the television antenna and the target operating state corresponding to the television antenna are determined by obtaining the frequency channel transmitted by the television device, so as to adjust the radiation performance of the television antenna, and make the television antenna perform well when working in the face of different frequency requirements of the electronic device.

In one embodiment, step S102 includes:

and acquiring a pre-generated information table.

Determining a target working state corresponding to the target frequency according to the information table; and the information table stores the incidence relation between the preset frequency and the preset working state.

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 a preset incidence relation table of preset frequency and preset working state, when the frequency channel of the television antenna is changed, the corresponding target working state can be obtained, and the current working state is adjusted to the target working state.

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

s201, sequentially adjusting the current working state of the antenna to each preset working state, controlling the antenna to scan electromagnetic waves according to a preset frequency sequence in each preset working state, and obtaining a power value of the electromagnetic waves at each preset frequency.

In application, the preset working states are preset working states of the television antenna during working, and the television antenna can receive electromagnetic wave signals with certain power values under the same or different working frequencies by working under different preset working states. 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 denoted by reference numeral 13, the highest frequency is 478MHz, the lowest frequency is 470MHz, and the intermediate frequency is 474MHz, in this embodiment, the corresponding frequency channel is defined to be represented by the intermediate frequency of the frequency channel, if the operating state of the environment where the television antenna is located is a1 (one sub-antenna operates), in this operating state, the television antenna scans the electromagnetic waves and obtains the corresponding power value according to the preset frequency sequence (the frequencies from 474MHz to 954MHz in table 1 change from small to large), then the operating state of the environment where the television antenna is located is changed to a2 (two sub-antennas operate), and scans the electromagnetic waves and obtains the corresponding power value according to the preset frequency sequence again.

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

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

In application, the preset threshold is a preset power value, and whether the power value of the electromagnetic wave signal obtained by the television antenna in the corresponding working state and the corresponding frequency is greater than the preset threshold is judged, so that the television equipment can normally play the program of the corresponding frequency channel. And if the power value of the acquired electromagnetic wave signal is greater than a preset threshold value under the corresponding preset working state and the corresponding preset frequency of the television antenna, establishing and storing an incidence relation between the current preset frequency and the current preset working state. The association relationship may be stored in the form of a table in the television antenna.

In this embodiment, by presetting each working state when the television antenna works, the television antenna sequentially works in the corresponding working state, scans electromagnetic wave signals of preset frequencies in different frequency channels, and when the power value of the scanned electromagnetic wave signals is greater than a preset threshold value, establishes and stores an information table containing the association relationship between the preset frequencies and the current preset working state, so that when the television antenna receives a frequency channel replaced by the television equipment, the working state of the antenna can be flexibly adjusted according to the information table, and further the radiation performance of the television antenna is adjusted, so that the antenna performs well when working in the face of different frequency requirements of the electronic equipment.

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 working states.

S302, if the preset frequency is associated with the preset working states, correspondingly obtaining power values of the electromagnetic waves of the antenna under the preset working states and the preset frequency.

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

For example, assuming that the operating state represents 10 different operating state conditions of the television antenna, the television antenna scans the electromagnetic wave signal at the frequency of 474MHz, the power value of the scanned electromagnetic wave signal is greater than the preset threshold value when the operating state condition is 1, the power value of the obtained electromagnetic wave signal is also greater than the preset threshold value when the operating state condition is 2, and the power values of the electromagnetic wave signals scanned under other operating state conditions are not greater than the preset threshold value, at this time, the information table may store the association relationship established between the preset frequency 474MHz and the operating state condition 1, and also store the association relationship established between the preset frequency 474MHz and the operating state condition 2.

And S303, determining an optimal preset working state according to the power value of the electromagnetic wave obtained by the antenna under each preset working state and the preset frequency.

S304, keeping the incidence relation between the preset frequency and the optimal preset working state in the information table, and deleting the incidence relation between the preset frequency and other preset working states.

In application, if one preset frequency is associated with a plurality of preset working states in an information table, acquiring power values of electromagnetic waves obtained by the television antenna under each preset working state and the preset frequency, determining the working state corresponding to the maximum power value as the optimal preset working state, storing the association relationship between the preset frequency and the optimal preset working state in the information table, and deleting the association relationship between the preset frequency and other preset working states in the information table.

In other applications, if the operating status represents the operating status conditions of 10 different television antennas, and the number of 1-10 represents the difficulty of using the corresponding operating status, the difficulty of adjusting the current operating status to the target operating status corresponding to the operating status with larger number is increased, or the power consumption of the corresponding television antenna is increased when the operating status with larger number is used. For example, if the operating state 1 represents that the power consumption of one sub-antenna in the tv antenna is P1, and the operating state 2 represents that the power consumption of two sub-antennas in the tv antenna is P2, and the power consumption P2 is greater than the power consumption P1. When the television antenna scans the electromagnetic wave signal at the operating frequency of 474MHz, under the condition that the operating state condition is 1 and the operating state condition is 2, if the obtained power values of the electromagnetic wave meet the requirements, the operating state with lower power consumption can be selected as the optimal preset operating state and the association relationship is established, which is not limited to this.

In this embodiment, the information table is updated by comparing a plurality of power values scanned by the television antenna under the association relationship established in the information table, and selecting and storing the association relationship between the preset frequency and the optimal preset working state, so that the antenna can be adjusted to the optimal antenna working state according to the target frequency, and further the radiation performance of the television antenna is optimal, and the television antenna performs well when working in the face of different frequency requirements of the electronic device.

In other embodiments, after step S202, that is, after the preset operating state 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 operating state 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 preset working state, and generating an information table according to the incidence relation between the preset frequency and the optimal preset working state. Namely, in the process of establishing the information table, the information table of the incidence relation between the preset frequency and the optimal preset working state is directly generated, and the subsequent process of updating the information table is omitted, so that the process is not limited.

It can be understood that, since the radiators are located at different positions, different radiators have different abilities of receiving electromagnetic wave signals in different directions when operating independently. It can be understood that different numbers of radiators can be set to operate simultaneously to form different preset operating states, which is not described herein again.
