Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purposes of explanation, details are set forth in order to provide a thorough understanding of the present application. It will be apparent to one skilled in the art that the present application can be practiced without the specific details presented herein. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0073] First, the terms related to the present application are explained:

[0074] ATSC 3.0: ATSC 3.0 (Advanced Television Systems Committee 3.0) is a new generation of digital television standard adopted by the broadcast television industry. It is an upgrade and improvement of the previous ATSC 1.0 standard, aiming to provide higher bandwidth and higher video resolution, richer broadcast television experience. The ATSC ATSC3.0 standard is a layered structure, which defines the standards of each layer from the physical layer, the transmission layer, the application layer, and the security layer.

[0075] Modulation mode: The modulation mode refers to a technology or method used in a wireless communication system to convert digital information into an analog signal for transmission. The modulation mode determines how the signal is transmitted and demodulated in the wireless medium. In the embodiments of the present application, a modulation mode is selected as a test standard, but the present solution is not limited to this modulation mode and is suitable for any modulation mode. The modulation mode is frequency 569MHz, code rate (coding rate) = 12 / 15, the number of multicarriers is 32K, and the interval protection length is 1024 symbol numbers.

[0076] The embodiments of the present application provide a signal strength determination method and device and electronic equipment. Specifically, the embodiments of the present application provide a signal strength determination device suitable for electronic equipment, which includes display equipment such as a television (such as a liquid crystal display television, an LED television, a radio frequency television, etc.), a mobile phone, and can also be used in other smart devices that can receive signals and display images (such as a computer, a tablet computer, a smart watch, smart glasses, etc.).

[0077] In the prior art, the ATSC 3.0 standard does not define specific standards for the signal strength progress bar, so different customers or enterprises have different signal strength progress bar algorithms in the determination and display of the signal strength progress bar. However, the results of the signal strength calculated by the existing algorithm for defining the signal strength progress bar are linearly changed, and cannot reflect the change in signal strength with high sensitivity in certain conditions that need to be paid special attention to.

[0078] Specifically, the signal strength determination method in the embodiments of the present application includes: obtaining an input signal level value and calculating a target signal level value; determining a target function from a plurality of calculation functions of a preset signal strength algorithm based on the calculated target signal level value; and finally calculating and processing the target signal level value using the target function to obtain a signal strength value and displaying the signal strength value in a display area of a target device.

[0079] In summary, the preset signal strength algorithm in the embodiments of the present application can divide the signal strength curve into five segments, which can reflect the change in signal strength with high sensitivity in certain conditions that need to be paid special attention to, and reflect the change in signal strength with low sensitivity in certain conditions that do not need to be paid special attention to.

[0080] By using the embodiments of the present application, the sensitivity can be automatically adjusted according to different signal strength ranges to adapt to the change in signal strength under different conditions, which realizes the technical effect of more clearly displaying the change in signal strength in the condition range that needs to be paid special attention to in a limited display range and improving the user experience.

[0081] The following are described in detail, respectively. It should be noted that the order of the following embodiments is not limited as the priority order of the embodiments.

[0082] Referring to FIG. 1, FIG. 1 is a flowchart of a signal strength determination method provided by an embodiment of the present application. Although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the figure. Specifically, the specific process of the signal strength determination method is as follows:

[0083] S101: calculating a target signal level value, wherein the target signal level value is calculated based on an input signal level value and a reference signal level value;

[0084] In the embodiment of the present application, before calculating the target signal level value, the input signal level value received by the target device is first obtained; at the same time, the reference signal level value set in advance by the target device is obtained.

[0085] Further, according to a pre-set difference calculation formula, the difference between the input signal level value and the reference signal level value is calculated, and the obtained difference is the target signal level value.

[0086] It should be noted that in the embodiment of the present application, Pref can be used to represent the pre-set reference signal level value, with a unit of dBm, corresponding to the sensitivity data in the mode; Prec is used to represent the input signal level value, with a unit of dBm; the pre-set difference calculation formula is Prel = Prec – Pref, wherein Prel represents the signal level value actually received by the target device, i.e. the target signal level value, with a unit of dB.

[0087] As an optional embodiment, taking a radio frequency television as the target device, a frequency of 569 MHz as the modulation mode, a code rate of 12 / 15, a number of 32K of multicarriers, a gap protection length of 1024 symbols, and a bandwidth of 6 MHz as examples. The signal strength value Prec is obtained from the high frequency head of ATSC 3.0, and then the target signal level value Prel is calculated according to the difference calculation formula: Prel = Prec – Pref. In the embodiment of the present application, the reference signal level value Pref can be taken as -80 dBm.

[0088] It should be noted that the "high frequency head" refers to a technology in the physical layer, also known as "high frequency channel head". It is used to provide additional protection and interference resistance in wireless transmission. The signal strength value obtained from the high frequency head of ATSC3.0 is the input signal level value described above. The target device includes but is not limited to the above-mentioned radio frequency television, which can be a smart device capable of receiving signals and displaying images, such as: TV, mobile phone, computer, tablet computer, smart watch, smart glasses, etc.; The target device can also have a signal strength indication function, which can be realized by a signal strength indicator (Signal Strength Indicator). The signal strength indicator is applied in the target device to display or measure the signal strength. The signal strength determination method is run on the target device, and the signal strength is displayed through the signal strength indication function.

[0089] In addition, the value of the reference signal level value Pref is only an example, which can be modified or set according to different devices, different models of devices, and various factors such as actual use scenarios and use environments. The difference calculation formula: Prel = Prec - Pref can also be adjusted or modified accordingly according to the actual situation.

[0090] S102: Determine the target function from the preset signal strength algorithm based on the target signal level value.

[0091] In the embodiments of the present application, the target signal level value is calculated to determine the numerical interval to which the target signal level value belongs.

[0092] It should be noted that the numerical interval is set to the first interval, the second interval, the third interval, the fourth interval and the fifth interval; The maximum value of the first interval is less than the minimum value of the second interval, the maximum value of the second interval is less than the minimum value of the third interval, the maximum value of the third interval is less than the minimum value of the fourth interval, and the maximum value of the fourth interval is less than the minimum value of the fifth interval.

[0093] As an optional embodiment, still taking the target device as a radio frequency television, the modulation mode as frequency 569 MHz, the code rate as 12 / 15, the number of multicarriers as 32K, and the interval guard length as 1024 symbol numbers, and the bandwidth as 6 MHz as an example. In the embodiment of the present application, the above five numerical intervals can be respectively set as: the first interval (-∞, -15), the second interval [-15, 0), the third interval [0, 20), the fourth interval [20, 35) and the fifth interval [35, +∞), wherein -15 is the minimum value of the second interval, 0 is the minimum value of the third interval, 20 is the minimum value of the fourth interval, and 35 is the minimum value of the fifth interval.

[0094] It should be further noted that the number of the above numerical intervals is not specifically limited, and can be set as five or other numbers; and the numerical range of each numerical interval is also not specifically limited, and the numerical range of each numerical interval can be modified or set according to different device types, different models of the same device type, and various factors such as actual use scenarios and use environments.

[0095] In the embodiment of the present application, the corresponding calculation function of the above numerical interval is obtained in advance, and the calculation function corresponding to the above numerical interval is determined as the above target function.

[0096] It should be noted that the above preset signal strength algorithm includes a plurality of different calculation functions, and each interval in the above plurality of numerical intervals corresponds to a calculation function.

[0097] As an optional embodiment, SSI can be used to represent the numerical value of the signal strength progress, and different numerical intervals correspond to a calculation function of the signal strength progress numerical value, for example: the first interval (-∞, -15) can use "SSI = 0" to represent the signal strength progress numerical value; the second interval [-15, 0) can use "SSI = (2 / 3)*(Prel+15)" to represent the signal strength progress numerical value; the third interval [0, 20) can use "SSI = 4*Prel+10" to represent the signal strength progress numerical value; the fourth interval [20, 35) can use "SSI = (2 / 3)*(Prel-20)+90" to represent the signal strength progress numerical value; and the fifth interval [35, +∞) can use "SSI = 100" to represent the signal strength progress numerical value.

[0098] Optionally, using the calculation function in the above embodiment, it can be seen that the signal strength progress numerical value corresponding to the first interval is 0, the signal strength progress numerical value corresponding to the second interval is 0 to 10, the signal strength progress numerical value corresponding to the third interval is 10 to 90, the signal strength progress numerical value corresponding to the fourth interval is 90 to 100, and the signal strength progress numerical value corresponding to the fifth interval is 100.

[0099] That is, the target signal level value which needs extra attention of the user is in the range of [0, 20), and the signal strength progress value corresponding to the target level value can be displayed in the range of 10-90 of the progress bar by using the calculation function of SSI=(2 / 3)*(Prel+15) corresponding to the interval; and the target signal level value which does not need extra attention is only in the range of 0-10 and 90-100 of the intensity progress bar; the change of the signal strength in the range of 10-90 is displayed with high sensitivity, and the user can intuitively and simply see the change of the signal strength, which can facilitate the user to adjust the signal, for example, adjust the antenna position and length, and improve the user experience.

[0100] Optionally, as shown in FIG. 2, FIG. 2 is a flowchart of a method for determining the numerical interval to which the target signal level value belongs provided by the embodiment of the application. Although the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the figure. Specifically, the specific process of the method for determining the numerical interval to which the target signal level value belongs is as follows:

[0101] As an optional embodiment, the size relationship between the target signal level value and the first preset value, the second preset value, the third preset value and the fourth preset value is determined to obtain a determination result; and the numerical interval to which the target signal level value belongs is determined based on the determination result.

[0103] Optionally, in the above embodiment, the first preset value is set to be -15, the second preset value is set to be 0, the third preset value is set to be 20, and the fourth preset value is set to be 35.

[0104] If the target signal level value is less than the first preset value, it is determined that the target signal level value belongs to the first interval, wherein the calculation function corresponding to the first interval is a first function.

[0105] Specifically, when the target signal level value Prel is less than -15 dB, the corresponding numerical interval is the first interval (-∞, -15), and the corresponding first function is: the signal strength progress value SSI=0, and the corresponding signal strength progress value is 0.

[0106] If the target signal level value is less than the second preset value and greater than or equal to the first preset value, it is determined that the target signal level value belongs to the second interval, wherein the calculation function corresponding to the second interval is a second function.

[0107] Specifically, when the target signal level value Prel is greater than or equal to -15 dB and less than 0 dB, the corresponding numerical interval is the second interval [-15, 0), and the corresponding second function is: signal strength progress value SSI = (2 / 3)*(Prel+15), and the corresponding signal strength progress value is 0 to 10.

[0108] If the target signal level value is less than the third preset value and greater than or equal to the second preset value, it is determined that the target signal level value belongs to the third interval, wherein the calculation function corresponding to the third interval is a third function.

[0109] Specifically, when the target signal level value Prel is greater than or equal to 0 dB and less than 20 dB, the corresponding numerical interval is the third interval [0, 20), and the corresponding third function is: signal strength progress value SSI = 4*Prel+10, and the corresponding signal strength progress value is 10 to 90.

[0110] If the target signal level value is less than the fourth preset value and greater than or equal to the third preset value, it is determined that the target signal level value belongs to the fourth interval, wherein the calculation function corresponding to the fourth interval is a fourth function.

[0111] Specifically, when the target signal level value Prel is greater than or equal to 20 dB and less than 35 dB, the corresponding numerical interval is the fourth interval [20, 35), and the corresponding fourth function is: signal strength progress value SSI = (2 / 3)*(Prel-20)+90, and the corresponding signal strength progress value is 90 to 100.

[0112] If the target signal level value is greater than or equal to the fourth preset value, it is determined that the target signal level value belongs to the fifth interval, wherein the calculation function corresponding to the fifth interval is a fifth function.

[0113] Specifically, when the target signal level value Prel is greater than or equal to 35 dB, the corresponding numerical interval is the fifth interval [35, +∞), and the corresponding fifth function is: signal strength progress value SSI = 100, and the corresponding signal strength progress value is 100.

[0114] As an optional embodiment, the test result obtained by testing the signal strength progress value by using the above plurality of calculation functions is shown in Table 1:

[0119] In the embodiment of the present application, the target signal level value is substituted into the target function, and the signal strength value is obtained; and the signal strength value is displayed on the target display area of the target device.

[0120] Optionally, taking the above numerical range and the corresponding calculation function as an example, if the value of the target signal level value Prel is less than -15dB, the signal strength progress value SSI is 0; if the value of the target signal level value Prel is -15dB≤Prel<0dB, the signal strength progress value SSI is (2 / 3)*(Prel+15); if the value of the target signal level value Prel is 0dB≤Prel<20dB, the signal strength progress value SSI is 4*Prel+10; if the value of the target signal level value Prel is 20dB≤Prel<35dB, the signal strength progress value SSI is (2 / 3)*(Prel-20)+90; and if the value of the target signal level value Prel is Prel≥35dB, the signal strength progress value SSI is 100.
