All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, an embodiment of the present invention provides a method for setting parameters for a satellite access port, where the method includes:
step 101: aiming at any access port used for accessing a satellite in receiving equipment, the receiving equipment determines the frequency point information of the satellite corresponding to the access port;
102, the receiving equipment determines a L NB frequency value capable of locking the frequency points in the frequency point information from preset L NB frequency values;
and 103, setting the L NB frequency of the docking port by the receiving equipment according to the determined L NB frequency value.
For a digital satellite receiving device, a plurality of access ports are provided, each access port can be accessed to a satellite, the satellite accessed to the access port can be default equipment or can be selected by a user, and no matter what mode is adopted, the satellite set by the user or the satellite set by the default equipment of the access port belongs to the satellite corresponding to the access port; and if the user does not select, regarding the satellite set by default in the equipment as the satellite corresponding to the access port, and if the user selects, regarding the satellite selected by the user as the satellite corresponding to the access port.
The user may also choose not to access the satellite at the access port, and at this time, the access port may be considered as having no corresponding satellite.
The user can set the satellite that the access mouth corresponds and the figure that receiving equipment inserts the satellite by oneself, and receiving equipment can provide certain display interface and be used for the user to set up, sets up the satellite that corresponds of access mouth and the figure that inserts the satellite, and receiving equipment can confirm the satellite that corresponds of every access mouth according to user's setting.
The method includes the steps that frequency point information, namely frequency point information corresponding to a satellite, can be set for each satellite receiving device, and the frequency point information can pass through frequency values of frequency points (TP) with signals on the satellite which are verified for many times, and can also be frequency values of the frequency points with the signals which are obtained through network resources.
It should be noted that the frequency point information may be a frequency value of a single frequency point, that is, the frequency point information includes at least one group of frequency points, and each group of frequency points includes one frequency point; or the frequency value may be a frequency value of a combined frequency point of a high-segment frequency point and a low-segment frequency point, that is, the frequency point information includes at least one group of frequency points, and each group of frequency points includes a high-segment frequency point and a low-segment frequency point. The frequency point information corresponding to the satellite may include a group of frequency points, or may include multiple groups of frequency points.
Taking a ku-band satellite as an example, the effective transmission frequency range of the ku-band satellite is 10750-12750 MHz, and if the frequency values of the frequency points of the ku-band satellite with signals are 10800MHz and 10850MHz, the frequency point information corresponding to the ku-band satellite can be set to be 10800MHz, also can be set to be 10850MHz, also can be set to be two groups of frequency points, that is, two frequency values of 10800MHz and 10850MHz are included; the effective transmission frequency range of the ku-band satellite can also be divided into two sections, namely a low-section frequency range and a high-section frequency range, for example, the low-section frequency range is 10750-11700 MHz, and the high-section frequency range is 11700-12750 MHz, so that the frequency point of the ku-band satellite with signals is a combined frequency point of the high-section frequency point and the low-section frequency point, for example, 11500MHz/12000MHz and 11700MHz/12500MHz, the frequency point information corresponding to the ku-band satellite can be set to 11500MHz/12000MHz, also can be set to 11700MHz/12500MHz, and also can be set to the frequency values of two combined frequency points, namely, 11500MHz/12000MHz and 11700MHz/12500 MHz.
For any satellite, the effective transmission frequency range of the satellite can be divided into two ranges, namely a low-band frequency range and a high-band frequency range, the frequency points with the frequency belonging to the high-band frequency range are high-band frequency points, and the frequency points with the frequency belonging to the low-band frequency range are low-band frequency points.
An L NB frequency initial value may be set for each satellite receiving device, where the L NB frequency initial value may be set by the receiving device according to the frequency point information corresponding to each satellite, that is, the receiving device may set one L NB frequency initial value, so that the receiving device may lock the frequency points in the frequency point information corresponding to the satellite by using the L NB frequency initial value.
It should be noted that when the frequency point information includes one frequency point, that is, the frequency point information includes a group of frequency points, and each group of frequency points includes one frequency point, locking the frequency point in the frequency point information corresponding to the satellite means locking the frequency point; when the frequency point information comprises a combined frequency point of a high-section frequency point and a low-section frequency point, namely the frequency point information comprises a group of frequency points, each group of frequency points comprises the high-section frequency point and the low-section frequency point, and the locking of the frequency points in the frequency point information corresponding to the satellite means that both the high-section frequency point and the low-section frequency point are locked; when the frequency point information comprises a plurality of frequency points, namely the frequency point information comprises a plurality of groups of frequency points, and each group of frequency points comprises one frequency point, the locking of the frequency points in the frequency point information corresponding to the satellite means that the plurality of frequency points are all locked; when the frequency point information comprises a plurality of combined frequency points of high-section frequency points and low-section frequency points, namely the frequency point information comprises a plurality of groups of frequency points, each group of frequency points comprises the high-section frequency points and the low-section frequency points, and the locking of the frequency points in the frequency point information corresponding to the satellite means that the high-section frequency points and the low-section frequency points are all locked.
The receiving device may be provided with a preset L NB frequency value, where the preset L NB frequency value may be a L NB frequency value that the receiving device can currently support, or may be a L NB frequency value that the receiving device can support according to a satellite, and a preset L NB frequency value corresponding to the satellite may be set for one satellite.
In step 102, the receiving device determines a L NB frequency value capable of locking the frequency points in the frequency point information from preset L NB frequency values, where the method includes two cases:
in the first case, the frequency point information comprises at least one group of frequency points, and each group of frequency points comprises a high-section frequency point and a low-section frequency point;
when each group of frequency points in the frequency point information comprises a high frequency point and a low frequency point, the high frequency point and the low frequency point are required to be ensured to be locked, namely, two local oscillation frequencies, one high local oscillation frequency and one low local oscillation frequency, are required to be arranged in the L NB frequency value, the high frequency point is locked according to the high local oscillation frequency, and the low frequency point is locked according to the low local oscillation frequency.
The receiving equipment determines a L NBfrequency value which contains a high local oscillation frequency capable of locking a high-section frequency point in the frequency point information and a low local oscillation frequency capable of locking a low-section frequency point in the frequency point information from preset L NB frequency values;
it should be noted that, for an L NB frequency value containing two local oscillation frequencies, the higher frequency value is taken as the high local oscillation frequency of the L NB frequency value, and the lower frequency value is taken as the low local oscillation frequency of the L NB frequency value.
In the second case, the frequency point information comprises at least one group of frequency points, and each group of frequency points comprises one frequency point;
when each group of frequency points in the frequency point information includes one frequency point, it is necessary to ensure that each group of frequency points is locked, that is, there must be one local frequency in the L NBfrequency value, and the frequency point is locked according to the local frequency.
And the receiving equipment determines a L NB frequency value containing the local oscillation frequency capable of locking the frequency points in the frequency point information from preset L NB frequency values.
Before step 101, the receiving device determines that the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value of the satellite corresponding to the access port.
It should be noted that when the frequency point information includes a frequency point, the fact that the frequency point in the frequency point information cannot be locked means that the frequency point cannot be locked; when the frequency point information comprises a combined frequency point of a high-section frequency point and a low-section frequency point, the fact that the frequency point in the frequency point information cannot be locked means that both the high-section frequency point and the low-section frequency point cannot be locked; when the frequency point information comprises a plurality of frequency points, the fact that the frequency points in the frequency point information cannot be locked means that the plurality of frequency points cannot be locked; when the frequency point information comprises a plurality of combined frequency points of high-section frequency points and low-section frequency points, the fact that the frequency points in the frequency point information cannot be locked means that at least one high-section frequency point and at least one low-section frequency point cannot be locked.
When the satellite frequency point information contains a single frequency point, the L NB frequency initial value of the corresponding satellite only contains one local oscillation frequency, and when the satellite frequency point information contains a combined frequency point of a high-section frequency point and a low-section frequency point, the L NB frequency initial value of the corresponding satellite contains one high local oscillation frequency and one low local oscillation frequency.
After determining that the receiving device cannot lock the frequency points in the frequency point information according to the L NB frequency initial value of the satellite corresponding to the access port, the receiving device needs to determine L NBfrequency values capable of locking the frequency points in the frequency point information;
the receiving equipment determines a L NB frequency value capable of locking the frequency points in the frequency point information from preset L NB frequency values;
according to the L NB frequency initial value, the following two cases can be classified:
in case one, the L NB frequency initial value comprises a high local oscillation frequency and a low local oscillation frequency;
the receiving equipment determines a L NBfrequency value for locking a high-section frequency point and a low-section frequency point from preset L NB frequency values, wherein the determined L NB frequency value does not contain a low local oscillation frequency or a high local oscillation frequency in the L NB frequency initial value;
when the L NB frequency initial value includes a high local oscillation frequency and a low local oscillation frequency, the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value at this time, that is, the low frequency point in the frequency point information cannot be locked according to the low local oscillation frequency in the L NB frequency initial value, and the high frequency point in the frequency point information cannot be locked according to the high local oscillation frequency in the L NB frequency initial value.
The L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The preset L NB frequency values can be filtered, the L NB frequency values containing the low local frequency or the high local frequency in the L NB frequency initial values in the preset L NB frequency values are removed, because the frequency points cannot be locked according to the low local frequency or the high local frequency in the L NB frequency initial values, that is, as long as the L NBfrequency values contain one frequency value in the L NB frequency initial values, the local frequency cannot lock the high frequency point or the low frequency point in the frequency point information, and the L NB frequency values containing only one local frequency are removed, because the high frequency point and the low frequency point are not locked according to the local frequency;
and determining L NB frequency values in the filtered preset L NB frequency values one by one, judging whether high-section frequency points and low-section frequency points in the frequency point information can be locked or not until finding the first L NB frequency value which can lock the high-section frequency points and the low-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the filtered preset L NB frequency values may also be determined one by one, whether the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked is determined, one of the L NB frequency values that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information is selected as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the L NB frequency value in the middle of the frequency may be selected as the determined L NB frequency value, and the L NB frequency value with the largest frequency may also be selected as the determined L NB frequency value.
How to lock the frequency points in the frequency point information according to the L NB frequency value is described as follows:
when an L NB frequency value contains two local oscillation frequencies, namely a high local oscillation frequency and a low local oscillation frequency, frequency values of the high local oscillation frequency and a high frequency band are subtracted for obtaining a difference value of the high local oscillation frequency and the high frequency band, the receiving equipment judges whether the high frequency band can be locked according to the difference value of the high local oscillation frequency and the low local oscillation frequency, the difference value is usually sent to a tuning device (Tuner) in the receiving equipment, whether the high frequency band can be locked is determined according to a return value of the tuning device, the frequency values of the low local oscillation frequency and the low frequency band are subtracted for obtaining the difference value of the low local oscillation frequency and the low frequency band, the receiving equipment judges whether the low frequency band can be locked according to the difference value of the low local oscillation frequency and the difference value is usually sent to the tuning device in the receiving equipment, and whether the low frequency band can be locked is determined according to the return value of the tuning device.
L NB frequency value contains a local oscillator frequency, for a local oscillator frequency, subtracting the frequency value of the local oscillator frequency and the frequency value of the frequency point to obtain the difference value of the two, the receiving equipment judges whether the frequency point can be locked according to the difference value of the two, usually the difference value is sent to the tuning device in the receiving equipment, and whether the frequency point can be locked is determined according to the return value of the tuning device.
And secondly, determining preset L NB frequency values one by one without filtering.
Determining L NB frequency values in preset L NB frequency values one by one, judging whether high-section frequency points and low-section frequency points in frequency point information can be locked or not until finding the first L NB frequency value which can lock the high-section frequency points and the low-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the preset L NB frequency values may also be determined one by one, whether the high-segment frequency points and the low-segment frequency points in the frequency point information may be locked is determined, one of L0 NB frequency values of the high-segment frequency points and the low-segment frequency points in all the lockable frequency point information may be selected as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, a L NB frequency value with a middle frequency may be selected as the determined L NB frequency value, a L NB frequency value with a largest frequency may also be selected as the determined L NB frequency value, or a high local oscillation frequency or a low local oscillation frequency L NB frequency value without the L NB frequency initial value may also be selected as the determined L NB frequency value.
In case two, the L NB frequency initial value comprises a local oscillation frequency;
the receiving device determines a locked frequency point L NB frequency value from preset L NB frequency values, wherein the determined L NB frequency value is not equal to the L NB frequency initial value.
When the L NB frequency initial value contains one local oscillation frequency, the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value at this time, that is, the frequency point in the frequency point information cannot be locked according to the local oscillation frequency in the L NB frequency initial value.
The L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The preset L NB frequency values can be filtered, the L NB frequency values, which contain the local frequency in the L NB frequency initial value, in the preset L NB frequency values are removed, because the frequency points cannot be locked according to the local frequency in the L NB frequency initial value, that is, the frequency points in the frequency point information cannot be locked as long as the L NB frequency values contain the local frequency value in the L NBfrequency initial value, and the L NB frequency values containing two local frequency points are removed at the same time, because the combination of the high-segment frequency points and the low-segment frequency points is locked according to the L NB frequency values of the two local frequency points;
and determining L NB frequency values in the filtered preset L NB frequency values one by one, judging whether the frequency points in the frequency point information can be locked or not until finding the first L NB frequency value in the frequency point information which can be locked, and taking the first L NB frequency value meeting the conditions as the determined L NB frequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the filtered preset L NB frequency values may also be determined one by one, whether the frequency points in the frequency point information can be locked is determined, one of the L NB frequency values that can lock the frequency points in the frequency point information is selected as the determined L NB frequency value, and the selection principle may be set according to the actual situation, for example, the L NB frequency value with the middle frequency may be selected as the determined L NB frequency value, or the L NB frequency value with the largest frequency may be selected as the determined L NB frequency value.
And secondly, determining preset L NB frequency values one by one without filtering.
Determining L NB frequency values in preset L NB frequency values one by one, judging whether the frequency points in the frequency point information can be locked or not until finding the first L NB frequency value which can lock the frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NB frequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The method for selecting the frequency point information may also include determining L NB frequency values in preset L NB frequency values one by one, determining whether the frequency points in the frequency point information can be locked, selecting one of L0 NB frequency values that can lock the frequency points in the frequency point information as a determined L NB frequency value, and setting a selection principle according to an actual situation, for example, selecting a L NB frequency value with a middle frequency as a determined L NB frequency value, selecting a L NBfrequency value with a maximum frequency as a determined L NB frequency value, or selecting an L NB frequency value with a local oscillation frequency that does not include the L NB frequency initial value as a determined L NB frequency value.
The receiving device sets the L NB frequency of the access port according to the determined L NB frequency value.
For example, if the determined L NB frequency value is 9750MHz/10600MHz, the low local oscillation frequency value of L NBfrequency of the access port is set to 9750MHz, the high local oscillation frequency value is set to 10600MHz, and the receiving device can lock the frequency point according to the L NB frequency value, so as to acquire satellite data on the frequency point;
if the determined L NB frequency value is 9750MHz, the local oscillation frequency value of the L NB frequency of the access port is set to 9750MHz, and the receiving equipment can lock the frequency point according to the L NB frequency value, so as to acquire satellite data on the frequency point.
If the L NBfrequency value which can lock the frequency points in the frequency point information does not exist in the preset L NB frequency value, the receiving equipment selects a satellite from preset satellites to replace the satellite corresponding to the access port, and the step of determining the frequency point information of the satellite corresponding to the access port by the receiving equipment is returned.
The preset L NB frequency value does not have the L NBfrequency value which can lock the frequency points in the frequency point information, namely, the information cannot be obtained from the satellite corresponding to the access port at the moment, the current satellite setting has problems, and other satellites can be selected from the preset satellites, so that the receiving equipment can access other satellites through the access port.
The preset satellite can be set by the receiving equipment or can be set by a user, and the user can set the access port and select a satellite which the user wants to access; the preset satellite comprises relevant information of the satellite, and the relevant information of the satellite can comprise identification information of the satellite, frequency point information of the satellite and the like.
It should be noted that the preset satellite is generally determined before the process of setting the L NB frequency value, that is, the receiving device sets the preset satellite before the process of setting the L NB frequency value, or the receiving device reminds the user of setting the preset satellite before the process of setting the L NBfrequency value.
If the preset satellite corresponding to the access port is empty, it indicates that the access port is not accessed to the satellite, that is, the user does not access to the satellite at the access port, and the receiving device may prompt the user to select to access to the satellite, or set that the access port is not accessed to the satellite, and set that the access port not set by other users is accessed to other satellites.
The above parameter setting is performed after the receiving device determines that the frequency point in the frequency point information cannot be locked according to the L NBfrequency initial value of the satellite corresponding to the access port, and if the receiving device can lock the frequency point in the frequency point information according to the L NB frequency initial value of the satellite corresponding to the access port, that is, the frequency point can be effectively locked by the L NB frequency initial value of the satellite corresponding to the access port, and data on the frequency point is acquired, the receiving device sets the L NB frequency of the access port according to the L NB frequency initial value.
The receiving device judges whether the frequency point in the frequency point information can be locked according to the L NB frequency initial value of the satellite corresponding to the access port according to the following mode:
when the L NB frequency initial value comprises a high local oscillation frequency and a low local oscillation frequency, the receiving equipment judges whether a high-section frequency point and a low-section frequency point can be locked according to the L NB frequency initial value of the satellite corresponding to the access port;
that is, the receiving device determines whether to lock a high-segment frequency point in the frequency point information according to a high local oscillation frequency in the L NB frequency initial value of the satellite corresponding to the access port, and to lock a low-segment frequency point in the frequency point information according to a low local oscillation frequency in the L NB frequency initial value of the satellite corresponding to the access port;
if yes, determining that the L NB frequency initial value can lock the frequency point in the frequency point information, otherwise determining that the frequency point in the frequency point information cannot be locked.
The L NB frequency initial value comprises a local oscillator frequency, and the receiving equipment judges whether a frequency point can be locked according to the local oscillator frequency contained in the L NB frequency initial value;
if yes, determining that the L NB frequency initial value can lock the frequency point in the frequency point information, otherwise determining that the frequency point in the frequency point information cannot be locked.
When the L NB frequency initial value contains a high local oscillation frequency and a low local oscillation frequency, in addition to the fact that the frequency points in the frequency point information can be locked and the frequency points in the frequency point information cannot be locked according to the L NB frequency initial value, the method also comprises a condition that only part of the frequency points in the frequency point information can be locked according to the L NB frequency initial value, for example, only the high-section frequency points and the low-section frequency points in the frequency point information can be locked according to the L NB frequency initial value, only the low-section frequency points in the frequency point information can be locked according to the L NB frequency initial value, and the high-section frequency points can not be locked.
The following is presented in terms of these two cases:
under the first condition, according to the L NB frequency initial value, only the high-segment frequency point in the frequency point information can be locked, and the low-segment frequency point cannot be locked:
at this time, the receiving device can lock a high-section frequency point in the frequency point information according to a high local oscillation frequency in the L NB frequency initial value;
the receiving equipment cannot lock the low-section frequency point in the frequency point information according to the low local oscillation frequency in the L NB frequency initial value;
the receiving equipment determines a L NB frequency value capable of locking a high-section frequency point and a low-section frequency point from preset L NB frequency values, wherein the determined L NB frequency value comprises a high local oscillation frequency in the L NB frequency initial value, and the L NB frequency of the access port is set according to the determined L NB frequency value.
The L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The preset L NB frequency values can be filtered, the L NB frequency values containing the high local frequency in the L NB frequency initial values in the preset L NB frequency values are obtained, the high-section frequency points in the frequency point information can be locked according to the high local frequency in the L NB frequency initial values, namely, the high-section frequency points in the frequency point information can be locked as long as the L NB frequency values contain the high local frequency in the L NB frequency initial values, and meanwhile, the L NB frequency values containing only one local frequency are removed, because the high-section frequency points and the low-section frequency points are unlocked only according to the local frequency;
and determining L NB frequency values in the filtered preset L NB frequency values one by one, judging whether high-section frequency points and low-section frequency points in the frequency point information can be locked or not until finding the first L NB frequency value which can lock the high-section frequency points and the low-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the filtered preset L NB frequency values may also be determined one by one, whether the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked is determined, one of the L NB frequency values that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information is selected as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the L NB frequency value in the middle of the frequency may be selected as the determined L NB frequency value, and the L NB frequency value with the largest frequency may also be selected as the determined L NB frequency value.
When the high-section frequency point and the low-section frequency point in the frequency point information can be locked, the high-section frequency point can be locked only by judging whether the low-section frequency point in the frequency point information can be locked or not because the screened preset L NB frequency values all contain the high local oscillation frequency values in the L NB frequency initial value.
And secondly, determining preset L NB frequency values one by one without filtering.
Determining L NB frequency values in preset L NB frequency values one by one, judging whether high-section frequency points and low-section frequency points in frequency point information can be locked or not until finding the first L NB frequency value which can lock the high-section frequency points and the low-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The method may also determine L NB frequency values in preset L NB frequency values one by one, determine whether high-segment frequency points and low-segment frequency points in the frequency point information can be locked, select one of L0 NB frequency values of high-segment frequency points and low-segment frequency points in all frequency point information can be locked as a determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, a L NB frequency value with a middle frequency may be selected as a determined L NB frequency value, a L NB frequency value with a maximum frequency may be selected as a determined L NB frequency value, or a L NB frequency value including a high local frequency in the L NB frequency initial values may be selected as a determined L NB frequency value.
And in the second case, only the low-section frequency points in the frequency point information can be locked according to the L NB frequency initial value, and the high-section frequency points cannot be locked.
At this time, the receiving device can lock the low-segment frequency point in the frequency point information according to the low local oscillation frequency in the L NB frequency initial value;
the receiving equipment cannot lock the high-section frequency point in the frequency point information according to the high local vibration frequency in the L NB frequency initial value;
the receiving equipment determines a L NB frequency value capable of locking a low-stage frequency point and a high-stage frequency point from preset L NB frequency values, wherein the determined L NB frequency value comprises a low local oscillation frequency in the L NB frequency initial value, and the L NB frequency of the access port is set according to the determined L NB frequency value;
the L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The preset L NB frequency value can be filtered, the L NB frequency value containing the low local frequency in the L NB frequency initial value in the preset L NB frequency value is obtained, the low frequency segment can be locked according to the low local frequency in the L NB frequency initial value, namely, as long as the L NB frequency value contains the low local frequency value in the L NB frequency initial value, the low frequency segment in the frequency point information can be locked, and meanwhile, the L NB frequency value containing only one local frequency is removed, because the low frequency segment and the high frequency segment are not locked according to the local frequency;
and determining L NB frequency values in the filtered preset L NB frequency values one by one, judging whether the low-section frequency points and the high-section frequency points in the frequency point information can be locked or not until finding the first L NB frequency value which can lock the low-section frequency points and the high-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the filtered preset L NB frequency values may also be determined one by one, whether the low-segment frequency points and the high-segment frequency points in the frequency point information can be locked is determined, one of the L NB frequency values that can lock the low-segment frequency points and the high-segment frequency points in the frequency point information is selected as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the L NB frequency value that is in the middle of the frequency may be selected as the determined L NB frequency value, and the L NB frequency value that is the largest in frequency may also be selected as the determined L NB frequency value.
When judging whether the low-section frequency point and the high-section frequency point in the frequency point information can be locked, because the screened preset L NB frequency values all contain the low local oscillation frequency value in the L NB frequency initial value, that is, the low-section frequency point can be locked certainly, only whether the high-section frequency point in the frequency point information can be locked can be judged.
And secondly, determining preset L NB frequency values one by one without filtering.
Determining L NB frequency values in preset L NB frequency values one by one, judging whether high-section frequency points and low-section frequency points in frequency point information can be locked or not until finding the first L NB frequency value which can lock the high-section frequency points and the low-section frequency points in the frequency point information, and taking the first L NB frequency value which meets the conditions as the determined L NBfrequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The L NB frequency values in the preset L NB frequency values may also be determined one by one, whether the high-segment frequency points and the low-segment frequency points in the frequency point information may be locked is determined, and one of L0 NB frequency values of the high-segment frequency points and the low-segment frequency points in all the lockable frequency point information may be selected as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, a L NB frequency value with a middle frequency may be selected as the determined L NB frequency value, a L NB frequency value with a maximum frequency may also be selected as the determined L NB frequency value, and a L NB frequency value including a low local oscillation frequency in the L NB frequency initial values may also be selected as the determined L NB frequency value.
In the two cases that only part of frequency points in the frequency point information can be locked according to the L NB frequency initial value, if no L NB frequency value capable of determining locking of high-segment frequency points and low-segment frequency points exists in the preset L NB frequency value, the receiving device sets L NB frequency of the access port according to a local oscillation frequency capable of locking frequency points in the L NB frequency initial value.
Under the first condition, according to the L NB frequency initial value, only the high-segment frequency point in the frequency point information can be locked, and the low-segment frequency point cannot be locked:
the preset L NB frequency value does not have a L NB frequency value which can be used for determining locking of a high-section frequency point and a low-section frequency point and contains a high local vibration frequency in the L NB frequency initial value, and the receiving equipment sets the L NB frequency of the access port according to the high local vibration frequency in the L NB frequency initial value.
For example, the L NB frequency initial value is 9750MHz/10600MHz, if the high-segment frequency point in the frequency point information can be locked according to 10600MHz in the L NB frequency initial value, the low-segment frequency point in the frequency point information cannot be locked according to 9750MHz in the L NB frequency initial value, and the low-segment frequency point of the frequency point information cannot be locked according to a preset L NB frequency value including a L NB frequency value of 10600MHz, the receiving device sets the L NB frequency of the access port according to 10600MHz in the L NB frequency initial value, and sets that the L frequency only contains a high local oscillation frequency at this time.
And in case two, according to the L NB frequency initial value, only the low-segment frequency point in the frequency point information can be locked, and the high-segment frequency point cannot be locked:
the preset L NB frequency value does not have a L NB frequency value which can determine that the locked high-section frequency point and the locked low-section frequency point contain the low local oscillation frequency in the L NB frequency initial value, and the receiving equipment sets the L NB frequency of the access port according to the low local oscillation frequency in the L NB frequency initial value.
For example, the L NB frequency initial value is 9750MHz/10600MHz, if the low-segment frequency point in the frequency point information can be locked according to 9750MHz of the L NB frequency initial values, the high-segment frequency point in the frequency point information cannot be locked according to 10600MHz of the L NB frequency initial values, and the high-segment frequency point of the frequency point information cannot be locked according to a preset L NB frequency value including a L NB frequency value of 9750MHz, the receiving device sets the L NB frequency of the access port according to 9750MHz of the L NB frequency initial value, and sets that the L frequency only contains a low local oscillation frequency at this time.

step 207, if no L NB frequency value capable of determining locking of the high-section frequency point and the low-section frequency point exists in the preset L NB frequency value, setting L NBfrequency of the access according to the high local vibration frequency in the L NB frequency initial value;
step 208, the receiving equipment judges whether the low-segment frequency point in the frequency point information can be locked according to the L NB frequency initial value, if so, step 209 is executed, otherwise, step 211 is executed;
step 209, the receiving equipment determines a L NBfrequency value capable of locking a high-section frequency point from preset L NB frequency values, wherein the determined L NB frequency value comprises a low local oscillation frequency in a L NB frequency initial value;
step 210, if no L NB frequency value capable of determining locking of the high-section frequency point and the low-section frequency point exists in preset L NB frequency values, setting L NBfrequency of an inlet according to a low local oscillation frequency in L NB frequency initial values;
step 211, the receiving equipment determines a L NB frequency value for locking the high-section frequency point and the low-section frequency point from preset L NB frequency values, and the determined L NB frequency value does not contain the low local oscillation frequency or the high local oscillation frequency in the L NB frequency initial value;
step 212, the preset L NB frequency value does not have the L NBfrequency value which can lock the frequency points in the frequency point information, the receiving equipment selects a satellite from the preset satellites to replace the satellite corresponding to the access port, and the step 202 is returned.
As shown in fig. 3, for one of the access ports, taking an example that an L NB frequency initial value includes a local oscillation frequency, the method according to the embodiment of the present invention for setting parameters of the satellite access port includes:
step 301: the receiving equipment can determine a satellite corresponding to the access port according to the setting of the user;

Based on the same inventive concept, the present discovery embodiment further provides a receiving device for setting parameters for a satellite access port, because the principle of the receiving device for solving the problem is similar to the method for setting parameters for a satellite access port in the embodiment of the present invention, the implementation of the device may refer to the implementation of the method, and repeated details are not repeated.
As shown in fig. 4, a receiving device for setting parameters for a satellite access port according to an embodiment of the present invention includes a frequency point determining module 400, a frequency determining module 401, and a processing module 402:
a frequency point determining module 400, configured to determine, for any access port used for accessing a satellite, frequency point information of the satellite corresponding to the access port;
a frequency determining module 401, configured to determine, from preset L NB frequency values, a L NB frequency value that can lock a frequency point in the frequency point information;
a processing module 402, configured to set a L NB frequency of the access port according to the determined L NB frequency value.
For a digital satellite receiving device, a plurality of access ports are provided, each access port can be accessed to a satellite, the satellite accessed to the access port can be default equipment or can be selected by a user, and no matter what mode is adopted, the satellite set by the user or the satellite set by the default equipment of the access port belongs to the satellite corresponding to the access port; and if the user does not select, regarding the satellite set by default in the equipment as the satellite corresponding to the access port, and if the user selects, regarding the satellite selected by the user as the satellite corresponding to the access port.
The user may also choose not to access the satellite at the access port, and at this time, the access port may be considered as having no corresponding satellite.
That is, the user can set the number of the satellites corresponding to the access ports and the number of the receiving devices accessing the satellites by himself, the receiving devices can provide a certain display interface for the user to set, the satellites corresponding to the access ports and the number of the access satellites are set, and the receiving devices can determine the satellites corresponding to each access port according to the setting of the user.
The method includes the steps that frequency point information, namely frequency point information corresponding to a satellite, can be set for each satellite receiving device, and the frequency point information can pass through frequency values of frequency points (TP) with signals on the satellite which are verified for many times, and can also be frequency values of the frequency points with the signals which are obtained through network resources.
It should be noted that the frequency point information may be a frequency value of a single frequency point, that is, the frequency point information includes at least one group of frequency points, and each group of frequency points includes one frequency point; or the frequency value may be a frequency value of a combined frequency point of a high-segment frequency point and a low-segment frequency point, that is, the frequency point information includes at least one group of frequency points, and each group of frequency points includes a high-segment frequency point and a low-segment frequency point. The frequency point information corresponding to the satellite may include a group of frequency points, or may include multiple groups of frequency points.
Taking a ku-band satellite as an example, the effective transmission frequency range of the ku-band satellite is 10750-12750 MHz, and if the frequency values of the frequency points of the ku-band satellite with signals are 10800MHz and 10850MHz, the frequency point information corresponding to the ku-band satellite can be set to be 10800MHz, also can be set to be 10850MHz, also can be set to be two groups of frequency points, that is, two frequency values, that is, 10800MHz and 10850MHz are included; the effective transmission frequency range of the ku-band satellite can also be divided into two sections, namely a low-section frequency range and a high-section frequency range, for example, the low-section frequency range is 10750-11700 MHz, and the high-section frequency range is 11700-12750 MHz, so that the frequency point of the ku-band satellite with signals is a combined frequency point of the high-section frequency point and the low-section frequency point, for example, 11500MHz/12000MHz and 11700MHz/12500MHz, the frequency point information corresponding to the ku-band satellite can be set to 11500MHz/12000MHz, also can be set to 11700MHz/12500MHz, and also can be set to the frequency values of two combined frequency points, namely, 11500MHz/12000MHz and 11700MHz/12500 MHz.
An L NB frequency initial value may be set for each satellite receiving device, where the L NB frequency initial value may be set by the receiving device according to the frequency point information corresponding to each satellite, that is, the receiving device may set one L NB frequency initial value, so that the receiving device may lock the frequency points in the frequency point information corresponding to the satellite by using the L NB frequency initial value.
It should be noted that when the frequency point information includes one frequency point, that is, the frequency point information includes a group of frequency points, and each group of frequency points includes one frequency point, locking the frequency point in the frequency point information corresponding to the satellite means locking the frequency point; when the frequency point information comprises a combined frequency point of a high-section frequency point and a low-section frequency point, namely the frequency point information comprises a group of frequency points, each group of frequency points comprises the high-section frequency point and the low-section frequency point, and the locking of the frequency points in the frequency point information corresponding to the satellite means that both the high-section frequency point and the low-section frequency point are locked; when the frequency point information comprises a plurality of frequency points, namely the frequency point information comprises a plurality of groups of frequency points, and each group of frequency points comprises one frequency point, the locking of the frequency points in the frequency point information corresponding to the satellite means that the plurality of frequency points are all locked; when the frequency point information comprises a plurality of combined frequency points of high-section frequency points and low-section frequency points, namely the frequency point information comprises a plurality of groups of frequency points, each group of frequency points comprises the high-section frequency points and the low-section frequency points, and the locking of the frequency points in the frequency point information corresponding to the satellite means that the high-section frequency points and the low-section frequency points are all locked.
The receiving device may be provided with a preset L NB frequency value, where the preset L NB frequency value may be a L NB frequency value that the receiving device can currently support, or may be a L NB frequency value that the receiving device can support according to a satellite, and a preset L NB frequency value corresponding to the satellite may be set for one satellite.
The frequency determining module 401 determines a L NB frequency value capable of locking a frequency point in the frequency point information from preset L NB frequency values, where the determining includes two cases:
in the first case, the frequency point information comprises at least one group of frequency points, and each group of frequency points comprises a high-section frequency point and a low-section frequency point;
when each group of frequency points in the frequency point information comprises a high frequency point and a low frequency point, the high frequency point and the low frequency point are required to be ensured to be locked, namely, two local oscillation frequencies, one high local oscillation frequency and one low local oscillation frequency, are required to be arranged in the L NB frequency value, the high frequency point is locked according to the high local oscillation frequency, and the low frequency point is locked according to the low local oscillation frequency.
The frequency determining module 401 determines, from preset L NB frequency values, L NBfrequency values that include a high local oscillation frequency that can lock a high-segment frequency point in the frequency point information and a low local oscillation frequency that can lock a low-segment frequency point in the frequency point information;
in the second case, the frequency point information comprises at least one group of frequency points, and each group of frequency points comprises one frequency point;
when each group of frequency points in the frequency point information includes one frequency point, it is necessary to ensure that each group of frequency points is locked, that is, there must be one local frequency in the L NBfrequency value, and the frequency point is locked according to the local frequency.
The frequency determining module 401 determines, from preset L NB frequency values, a L NB frequency value that contains a local oscillation frequency that can lock a frequency point in the frequency point information.
The frequency determining module 401 determines that the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value of the satellite corresponding to the access port.
It should be noted that when the frequency point information includes a frequency point, the fact that the frequency point in the frequency point information cannot be locked means that the frequency point cannot be locked; when the frequency point information comprises a combined frequency point of a high-section frequency point and a low-section frequency point, the fact that the frequency point in the frequency point information cannot be locked means that both the high-section frequency point and the low-section frequency point cannot be locked; when the frequency point information comprises a plurality of frequency points, the fact that the frequency points in the frequency point information cannot be locked means that the plurality of frequency points cannot be locked; when the frequency point information comprises a plurality of combined frequency points of high-section frequency points and low-section frequency points, the fact that the frequency points in the frequency point information cannot be locked means that at least one high-section frequency point and at least one low-section frequency point cannot be locked.
When the satellite frequency point information contains a single frequency point, the L NB frequency initial value of the corresponding satellite only contains one local oscillation frequency, and when the satellite frequency point information contains a combined frequency point of a high-section frequency point and a low-section frequency point, the L NB frequency initial value of the corresponding satellite contains one high local oscillation frequency and one low local oscillation frequency.
After determining that the frequency module 401 cannot lock the frequency point in the frequency point information according to the L NB frequency initial value of the satellite corresponding to the access port, determining that the frequency module 401 needs to determine the L NB frequency value capable of locking the frequency point in the frequency point information;
the frequency determining module 401 determines a L NB frequency value capable of locking a frequency point in the frequency point information from preset L NB frequency values;
according to the L NB frequency initial value, the following two cases can be classified:
in case one, the L NB frequency initial value comprises a high local oscillation frequency and a low local oscillation frequency;
the frequency determining module 401 determines a L NB frequency value for locking a high-segment frequency point and a low-segment frequency point from preset L NB frequency values, where the determined L NB frequency value does not include a low local oscillation frequency or a high local oscillation frequency in the L NB frequency initial value;
when the L NB frequency initial value includes a high local oscillation frequency and a low local oscillation frequency, since the frequency determining module 401 cannot lock the frequency point in the frequency point information according to the L NB frequency initial value at this time, that is, the frequency determining module 401 cannot lock the low-segment frequency point in the frequency point information according to the low local oscillation frequency in the L NB frequency initial value, and the frequency determining module 401 cannot lock the high-segment frequency point in the frequency point information according to the high local oscillation frequency in the L NB frequency initial value.
The L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The frequency determining module 401 may filter the preset L NB frequency value, and remove the L NBfrequency value that contains the low local frequency or the high local frequency in the L NB frequency initial value in the preset L NBfrequency value, because the frequency point cannot be locked according to the low local frequency or the high local frequency in the L NB frequency initial value, that is, as long as the L NB frequency value contains one local frequency value in the L NB frequency initial value, the high frequency point or the low frequency point in the frequency point information cannot be locked, the frequency determining module 401 removes the L NB frequency value that only contains one local frequency, because only one local frequency is two of the high frequency point and the low frequency point that are not locked;
the frequency determining module 401 determines L NB frequency values in the filtered preset L NB frequency values one by one, the frequency determining module 401 determines whether the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked or not until a L NB frequency value that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information is found, and the frequency determining module 401 takes the L NB frequency value that meets the condition as the determined L NB frequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in the filtered preset L NB frequency values one by one, determine whether the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked, and select one of L NB frequency values of the high-segment frequency points and the low-segment frequency points in all the lockable frequency point information by the frequency determining module 401 as the determined L NB frequency value, where the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value with a middle frequency as the determined L NB frequency value, and may select an L NB frequency value with a maximum frequency as the determined L NB frequency value.
How to lock the frequency points in the frequency point information according to the L NB frequency value is described as follows:
when the L NB frequency value includes two local oscillation frequencies, that is, a high local oscillation frequency and a low local oscillation frequency, for a high local oscillation frequency, the frequency module 401 is determined to subtract frequency values of the high local oscillation frequency and a high frequency band to obtain a difference value between the high local oscillation frequency and the high frequency band, the frequency module 401 is determined to determine whether the high frequency band can be locked according to the difference value between the high local oscillation frequency and the high frequency band, the difference value is usually sent to a tuning device in the receiving device, whether the high frequency band can be locked is determined according to a return value of the tuning device, for a low local oscillation frequency, the frequency values of the low local oscillation frequency and the low frequency band are subtracted to obtain a difference value between the low local oscillation frequency and the low frequency band, the frequency module 401 is determined to determine whether the low frequency band can be locked according to the difference value between the low local oscillation frequency and the return value of the tuning device is determined to determine whether.
When the L NB frequency value contains one local oscillation frequency, the frequency determining module 401 subtracts frequency values of the local oscillation frequency and the frequency point for one local oscillation frequency to obtain a difference value between the two local oscillation frequencies, the frequency determining module 401 determines whether the frequency point can be locked according to the difference value between the two local oscillation frequencies, usually, the difference value is sent to the tuning device in the receiving device, and whether the frequency point can be locked is determined according to a return value of the tuning device.
And secondly, determining preset L NB frequency values one by one without filtering.
The frequency determining module 401 determines L NB frequency values in preset L NB frequency values one by one, determines whether high-segment frequency points and low-segment frequency points in the frequency point information can be locked or not until a L NB frequency value that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information is found, and the frequency determining module 401 takes the first L NBfrequency value that meets the conditions as the determined L NB frequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in preset L NB frequency values one by one, determine whether high-segment frequency points and low-segment frequency points in the frequency point information may be locked, and determine that the frequency determining module 401 selects one of L0 NB frequency values of high-segment frequency points and low-segment frequency points in all the lockable frequency point information as a determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select an L NB frequency value with a middle frequency as a determined L NB frequency value, may select a L NBfrequency value with a maximum frequency as a determined L NB frequency value, and may select a L NB frequency value of a high local oscillation frequency or a low local oscillation frequency that does not include an L NB frequency initial value as a determined L NB frequency value.
In case two, the L NB frequency initial value comprises a local oscillation frequency;
the determine frequency module 401 determines a locked frequency point L NB frequency value from preset L NB frequency values, where the determined L NB frequency value is not equal to the L NB frequency initial value.
When the L NB frequency initial value includes one local oscillation frequency, since the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value at this time, that is, the frequency determining module 401 cannot lock the frequency point in the frequency point information according to the local oscillation frequency in the L NB frequency initial value.
The L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The frequency determining module 401 may filter a preset L NB frequency value, and the frequency determining module 401 removes a L NB frequency value, which contains a local frequency in a L NB frequency initial value, from the preset L NB frequency value, because the frequency point cannot be locked according to the local frequency in the L NB frequency initial value, that is, as long as the L NBfrequency value contains the local frequency value in the L NB frequency initial value, the frequency point in the frequency point information cannot be locked, and the frequency determining module 401 simultaneously removes a L NB frequency value containing two local frequency points, which is because the frequency determining module 401 locks according to the L NB frequency value of the two local frequency points to include a high-segment frequency point and a low-segment frequency point combination;
the frequency determining module 401 determines L NB frequency values in the filtered preset L NB frequency values one by one, determines whether the frequency points in the frequency point information can be locked until finding the first L NB frequency value in the frequency point information that can be locked, and the frequency determining module 401 takes the first L NB frequency value that meets the condition as the determined L NB frequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in the filtered preset L NB frequency values one by one, determine whether the frequency points in the frequency point information can be locked, select one of all frequency point L NB frequency values in the frequency point information that can be locked by the frequency determining module 401 as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value that is the center of the frequency as the determined L NB frequency value, and the frequency determining module 401 may also select an L NB frequency value that is the largest in frequency as the determined L NB frequency value.
And secondly, determining preset L NB frequency values one by one without filtering.
The frequency determining module 401 determines L NB frequency values in preset L NB frequency values one by one, and determines whether the frequency points in the frequency point information can be locked until the frequency determining module 401 finds a L NB frequency value that can lock the frequency points in the frequency point information, and the frequency determining module 401 takes the first L NB frequency value that meets the condition as the determined L NB frequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in preset L NB frequency values one by one, determine whether the frequency points in the frequency point information may be locked, and the frequency determining module 401 selects one of L0 NB frequency values that may lock the frequency points in the frequency point information as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value that is centered in frequency as the determined L NB frequency value, and the frequency determining module 401 may also select a L NB frequency value that has the largest frequency as the determined L NB frequency value, or may select an L NBfrequency value that does not include a local oscillation frequency of the L NB frequency initial value as the determined L NB frequency value.
The processing module 402 sets the L NB frequency of the access port according to the determined L NB frequency value.
For example, if the L NB frequency value determined by the frequency determining module 401 is 9750MHz/10600MHz, the processing module 402 sets the low local oscillation frequency value of the L NB frequency of the access port to 9750MHz, and sets the high local oscillation frequency value to 10600MHz, so that the receiving device can lock the frequency point according to the L NB frequency value, and further acquire satellite data on the frequency point;
if the L NB frequency value determined by the frequency determining module 401 is 9750MHz, the processing module 402 sets the local oscillation frequency value of the L NB frequency of the access port to 9750MHz, and the receiving device can lock the frequency point according to the L NB frequency value, thereby acquiring satellite data on the frequency point.
If the L NBfrequency value which can lock the frequency point in the frequency point information does not exist in the preset L NB frequency value, the processing module 402 selects a satellite from preset satellites to replace the satellite corresponding to the access port, and returns to the step of determining the frequency point information of the satellite corresponding to the access port by the frequency point determining module 400.
The preset L NB frequency value does not have the L NBfrequency value capable of locking the frequency points in the frequency point information, that is, information cannot be acquired from the satellite corresponding to the access at this time, and the current satellite setting has a problem, and the processing module 402 may select another satellite from the preset satellites, so that the receiving device may access the other satellite through the access.
The preset satellite can be set by the receiving equipment or can be set by a user, and the user can set the access port and select a satellite which the user wants to access; the preset satellite comprises relevant information of the satellite, and the relevant information of the satellite can comprise identification information of the satellite, frequency point information of the satellite and the like.
It should be noted that the preset satellite is generally determined before the process of setting the L NB frequency value, that is, the receiving device sets the preset satellite before the process of setting the L NB frequency value, or the receiving device reminds the user of setting the preset satellite before the process of setting the L NBfrequency value.
If the preset satellite corresponding to the access port is empty, it indicates that the access port is not accessed to the satellite, that is, the user does not access to the satellite at the access port, and the processing module 402 may prompt the user to select to access to the satellite, or may set the access port not to access to the satellite, and set the access port not set by other users to access to other satellites.
The above parameter setting is performed after the frequency determining module 401 determines that the frequency point in the frequency point information cannot be locked according to the L NB frequency initial value of the satellite corresponding to the access port, and if the frequency determining module 401 can lock the frequency point in the frequency point information according to the L NB frequency initial value of the satellite corresponding to the access port, that is, the frequency point can be effectively locked by the L NB frequency initial value of the satellite corresponding to the access port, and data on the frequency point is acquired, the frequency determining module 401 sets L NBfrequency of the access port according to the L NB frequency initial value.
The frequency determining module 401 determines whether the frequency point in the frequency point information can be locked according to the L NB frequency initial value of the satellite corresponding to the access port as follows:
when the L NB frequency initial value includes a high local oscillation frequency and a low local oscillation frequency, the frequency determining module 401 determines whether a high-segment frequency point and a low-segment frequency point can be locked according to the L NB frequency initial value of the satellite corresponding to the access port;
that is, the frequency determining module 401 determines whether the high-segment frequency point in the frequency point information can be locked according to the high local oscillation frequency in the L NBfrequency initial value of the satellite corresponding to the access port, and the low-segment frequency point in the frequency point information can be locked according to the low local oscillation frequency in the L NB frequency initial value of the satellite corresponding to the access port;
if so, the frequency determining module 401 determines that the L NB frequency initial value can lock the frequency point in the frequency point information, otherwise, determines that the frequency point in the frequency point information cannot be locked.
The L NB frequency initial value includes a local oscillation frequency, and the frequency determining module 401 determines whether a frequency point can be locked according to the local oscillation frequency included in the L NB frequency initial value;
if so, the frequency determining module 401 determines that the L NB frequency initial value can lock the frequency point in the frequency point information, otherwise, determines that the frequency point in the frequency point information cannot be locked.
When the L NB frequency initial value includes a high local oscillation frequency and a low local oscillation frequency, except for a case that the frequency determining module 401 can lock a frequency point in the frequency point information and cannot lock a frequency point in the frequency point information according to the L NB frequency initial value, the frequency determining module 401 may lock only a part of frequency points in the frequency point information according to the L NB frequency initial value, and if the frequency determining module 401 can lock only a high-segment frequency point in the frequency point information and cannot lock a low-segment frequency point according to the L NB frequency initial value, the frequency determining module 401 may lock only a low-segment frequency point in the frequency point information and cannot lock a high-segment frequency point according to the L NB frequency initial value.
The following is presented in terms of these two cases:
in case one, the frequency determining module 401 can only lock the high-segment frequency points in the frequency point information according to the L NB frequency initial value, and cannot lock the low-segment frequency points:
at this time, the frequency determining module 401 can lock the high-segment frequency point in the frequency point information according to the high local oscillation frequency in the L NB frequency initial value;
the frequency determining module 401 cannot lock the low-segment frequency point in the frequency point information according to the low local oscillation frequency in the L NB frequency initial value;
the frequency determining module 401 determines a L NB frequency value capable of locking a high-stage frequency point and a low-stage frequency point from preset L NB frequency values, wherein the determined L NB frequency value comprises a high local oscillation frequency in the L NB frequency initial value, and the processing module 402 sets L NBfrequency of the access port according to the determined L NB frequency value;
the L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The frequency determining module 401 may filter a preset L NB frequency value, and obtain a L NB frequency value of a high local frequency in a L NB frequency initial value in the preset L NB frequency value, because a high-segment frequency point may be locked according to the high local frequency in the L NB frequency initial value, that is, as long as the L NB frequency value includes the high local frequency value in the L NB frequency initial value, the high-segment frequency point in the frequency point information may be locked, and at the same time, the frequency determining module 401 removes only a L NB frequency value including one local frequency, because only one local frequency is two of an unlocked high-segment frequency point and a low-segment frequency point;
the frequency determining module 401 determines L NB frequency values in the filtered preset L NB frequency values one by one, and determines whether high-segment frequency points and low-segment frequency points in the frequency point information can be locked or not until the frequency determining module 401 finds a L NB frequency value at which the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked first, and the frequency determining module 401 takes the L NB frequency value which meets the first requirement as the determined L NB frequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NBfrequency values of the filtered preset L NB frequency values one by one, and determine whether the high-segment frequency points and the low-segment frequency points in the frequency point information can be locked, where the frequency determining module 401 selects one of L NB frequency values of the high-segment frequency points and the low-segment frequency points in all the lockable frequency point information as the determined L NB frequency value, and a selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value in the middle of the frequency as the determined L NB frequency value, and the frequency determining module 401 may also select a L NB frequency value with the largest frequency as the determined L NB frequency value.
When the frequency determining module 401 determines whether to lock the high-segment frequency point and the low-segment frequency point in the frequency point information, since the screened preset L NB frequency values both include the high local oscillation frequency value in the L NB frequency initial value, that is, the high-segment frequency point can be locked, the frequency determining module 401 may only determine whether to lock the low-segment frequency point in the frequency point information.
And secondly, determining preset L NB frequency values one by one without filtering.
The frequency determining module 401 determines L NB frequency values in preset L NB frequency values one by one, and determines whether high-segment frequency points and low-segment frequency points in frequency point information can be locked or not, until the frequency determining module 401 finds a L NB frequency value that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information first, and the frequency determining module 401 takes the L NB frequency value that meets the condition as the determined L NB frequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in preset L NB frequency values one by one, and determine whether high-segment frequency points and low-segment frequency points in the frequency point information can be locked, the frequency determining module 401 may select one of L0 NB frequency values of high-segment frequency points and low-segment frequency points in all lockable frequency point information as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value in the middle of the frequency as the determined L NB frequency value, the frequency determining module 401 may also select an NB L frequency value with the largest frequency as the determined L NB frequency value, and the frequency determining module 401 may also select an L NB frequency value containing the high local frequency in the L NB frequency initial value as the determined L NB frequency value.
In case two, the frequency determining module 401 can only lock the low-segment frequency points in the frequency point information according to the L NB frequency initial value, and cannot lock the high-segment frequency points.
At this time, the frequency determining module 401 can lock the low-segment frequency point in the frequency point information according to the low local oscillation frequency in the L NB frequency initial value;
the frequency determining module 401 cannot lock a high frequency point in the frequency point information according to a high local oscillation frequency in the L NB frequency initial value;
the frequency determining module 401 determines a L NB frequency value capable of locking a low-stage frequency point and a high-stage frequency point from preset L NB frequency values, wherein the determined L NB frequency value comprises a low local oscillation frequency in the L NB frequency initial value, and the processing module 402 sets L NBfrequency of the access port according to the determined L NB frequency value;
the L NB frequency value can be determined from preset L NB frequency values in two ways;
in the first mode, the preset L NB frequency value is filtered, and then the L NB frequency value is determined.
The frequency determining module 401 may filter a preset L NB frequency value, and obtain a L NB frequency value containing a low local frequency in L NB frequency initial values in the preset L NB frequency value, because the low frequency may be locked according to the low local frequency in the L NB frequency initial values, that is, as long as the L NB frequency value contains the low local frequency in the L NB frequency initial values, the low frequency in the frequency point information may be locked, and at the same time, the frequency determining module 401 removes the L NB frequency value containing only one local frequency, because the local frequency is obtained according to that one local frequency is two of an unlocked low frequency and a high frequency;
the frequency determining module 401 determines L NB frequency values in the filtered preset L NB frequency values one by one, and determines whether the low-segment frequency points and the high-segment frequency points in the frequency point information can be locked or not, until the frequency determining module 401 finds a L NB frequency value at which the low-segment frequency points and the high-segment frequency points in the frequency point information can be locked first, and the frequency determining module 401 takes the L NB frequency value which meets the first condition as the determined L NB frequency value.
In practical application, because the preset L NB frequency value is filtered, that is, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, there is generally only one satisfying condition, that is, as long as a L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NBfrequency values of the filtered preset L NB frequency values one by one, and determine whether the low-segment frequency points and the high-segment frequency points in the frequency point information can be locked, where the frequency determining module 401 selects one of L NB frequency values of the low-segment frequency points and the high-segment frequency points in all the lockable frequency point information as the determined L NB frequency value, and a selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value with a middle frequency as the determined L NB frequency value, and the frequency determining module 401 may select a L NB frequency value with a maximum frequency as the determined L NB frequency value.
When the frequency determining module 401 determines whether the low-segment frequency point and the high-segment frequency point in the frequency point information can be locked, since the screened preset L NB frequency values both include the low local oscillation frequency value in the L NB frequency initial value, that is, the low-segment frequency point can be locked, the frequency determining module 401 may only determine whether the high-segment frequency point in the frequency point information can be locked.
And secondly, determining preset L NB frequency values one by one without filtering.
The frequency determining module 401 determines L NB frequency values in preset L NB frequency values one by one, and determines whether high-segment frequency points and low-segment frequency points in frequency point information can be locked or not, until the frequency determining module 401 finds a L NB frequency value that can lock the high-segment frequency points and the low-segment frequency points in the frequency point information first, and the frequency determining module 401 takes the L NB frequency value that meets the condition as the determined L NB frequency value.
In practical application, when it is determined one by one whether the high-segment frequency point and the low-segment frequency point in the frequency point information can be locked, only one of the conditions is satisfied, that is, as long as an L NB frequency value capable of locking the high-segment frequency point and the low-segment frequency point in the frequency point information is determined, the L NB frequency value can be used as the determined L NB frequency value.
The frequency determining module 401 may also determine L NB frequency values in preset L NB frequency values one by one, and determine whether a high-segment frequency point and a low-segment frequency point in the frequency point information can be locked, the frequency determining module 401 may select one of L0 NB frequency values of the high-segment frequency point and the low-segment frequency point in all the lockable frequency point information as the determined L NB frequency value, and the selection principle may be set according to an actual situation, for example, the frequency determining module 401 may select a L NB frequency value with a middle frequency as the determined L NB frequency value, the frequency determining module 401 may also select an NB L frequency value with a maximum frequency as the determined L NB frequency value, and the frequency determining module 401 may also select an L NB frequency value containing a low local oscillation frequency in the L NB frequency initial values as the determined L NB frequency value.
In the two cases that only part of the frequency points in the frequency point information can be locked according to the L NB frequency initial value, if no L NB frequency value capable of determining to lock a high-segment frequency point and a low-segment frequency point exists in the preset L NB frequency value, the frequency determining module 401 sets the L NB frequency of the access port according to the local oscillation frequency capable of locking the frequency points in the L NB frequency initial value.
In case one, the frequency determining module 401 can only lock the high-segment frequency points in the frequency point information according to the L NB frequency initial value, and cannot lock the low-segment frequency points:
the preset L NB frequency values do not have L NB frequency values which can determine locking of high-segment frequency points and low-segment frequency points and contain high local vibration frequencies in the L NB frequency initial values, and the frequency determining module 401 sets L NB frequency of the access port according to the high local vibration frequencies in the L NB frequency initial values.
For example, the L NB frequency initial value is 9750MHz/10600MHz, if the frequency determining module 401 can lock a high-segment frequency point in the frequency point information according to 10600MHz of the L NB frequency initial value, the frequency determining module 401 cannot lock a low-segment frequency point in the frequency point information according to 9750MHz of the L NB frequency initial value, and the frequency determining module 401 sets the L NB frequency of the access port according to 10600MHz of the L NB frequency initial value according to L NBfrequency values that the preset L NB frequency value includes 10600MHz, and sets that the L NBfrequency only contains a high local oscillation frequency.
In case two, the frequency determining module 401 can only lock the low-segment frequency point in the frequency point information according to the L NB frequency initial value, and cannot lock the high-segment frequency point:

For example, the L NB frequency initial value is 9750MHz/10600MHz, if the frequency determining module 401 can lock the low-segment frequency points in the frequency point information according to 9750MHz of the L NB frequency initial value, the frequency determining module 401 cannot lock the high-segment frequency points in the frequency point information according to 10600MHz of the L NB frequency initial value, and the frequency determining module 401 sets the L NB frequency of the access port according to 9750MHz of the L NB frequency initial value and sets L NB frequency to only contain low local oscillation frequencies when the frequency determining module 401 cannot lock the high-segment frequency points of the frequency point information according to L NBfrequency values including 9750MHz of the preset L NB frequency initial value.
