In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The embodiment provides a method for determining an operation parameter correction threshold based on a navigation system, as shown in fig. 1, including the following steps:

s101, when a correction threshold updating period is reached, determining an operation parameter value of an operation target at the current moment, wherein the operation parameter comprises a visual speed and a visual position;

illustratively, the correction threshold is used for defining a correction range of an operation target operation parameter, and correcting an operation track of the operation target according to the correction range to ensure normal operation of the operation target, wherein the operation target may be an object needing to realize self-operation by means of a navigation system, such as a rocket, an automobile, and the like. And every other correction threshold updating period, the rocket can re-determine the correction threshold of the next period, namely the maximum range of correction of the apparent velocity and the apparent position of the rocket in the next period. When the rocket navigation system sends out the correction signals of the visual speed and the visual position in the next period, whether the correction value of the visual speed and the visual position sent out by the rocket navigation system is in the range of the correction threshold or not is judged through the redetermined correction threshold, and when the correction value is in the range of the correction threshold, the correction is carried out, and when the correction value is not in the range of the correction threshold, the correction is not carried out. The present embodiment does not limit the type of the operation target, and those skilled in the art can determine the operation target according to the needs.

The update period of the correction threshold may be in the order of milliseconds, seconds or minutes, which is not limited in the embodiment of the present application and can be determined by a person skilled in the art according to actual needs. Taking the update period of the correction threshold as ten milliseconds as an example, the correction threshold is updated every ten milliseconds. When the update period of the correction threshold is reached, the mode of determining the apparent speed and the apparent position of the current-time operation target may be that the current-time operation parameter is obtained through a corresponding operation parameter acquisition device, or that the current-time operation parameter is obtained by obtaining the apparent acceleration of the inertia component and performing internal calculation.

And S102, determining a correction threshold of the operation parameter in the next period based on the operation parameter value of the current operation target.

For example, based on the operation parameter value of the operation target at the current time, the method for determining the correction threshold of the operation parameter in the next period may be to obtain the apparent speed and apparent position correction threshold according to the following formula:

；

wherein the content of the first and second substances,the coefficient is set according to the azimuth error of actual aiming of the rocket, the unit of k is radian, and the size of k can be 6.10865e-3 radians specifically;indicating a view position correction threshold;indicating a visual velocity correction threshold;representing the apparent position of the running target at the current moment;indicating the apparent velocity of the operational target at the current time.

In the method for determining the operation parameter correction threshold based on the navigation system, the operation parameter value of the operation target is calculated in the update period of the correction threshold, the correction threshold of the operation parameter of the next period is determined, the correction threshold is set by the operation parameter of the actual operation target, and compared with the prior art in which the correction threshold is set only according to the rocket operation time, the method for determining the correction threshold by the real-time operation parameter of the operation target is implemented, so that a more accurate standard is provided for the selection of the correction parameter of the operation target, and the accuracy rate of the operation target in correcting the operation track is improved.

As an optional implementation manner of this embodiment, step S102 includes:

firstly, acquiring a minimum value of a correction threshold corresponding to an operation parameter;

for example, the minimum modification threshold value corresponding to the operating parameter may be a minimum apparent velocity modification threshold value and a minimum apparent position modification threshold value. The obtaining mode may be obtained from a memory in which the minimum value of the apparent velocity correction threshold and the minimum value of the apparent position correction threshold are stored in advance, or may be obtained directly from the minimum value data of the correction threshold input in real time from the outside.

And secondly, determining a correction threshold of the operation parameter in the next period based on the operation parameter value of the current operation target and the corresponding minimum value of the correction threshold.

For example, the manner of determining the correction threshold of the operating parameter in the next period based on the operating parameter value of the operating target at the current time and the corresponding minimum value of the correction threshold may be determined by the following formula:

wherein S is_minCorrecting the minimum value of the threshold for the visual position; v_minModifying the threshold minimum for apparent velocity, S_min、V_minCan be determined according to the navigation deviation caused by the initial reference error of the operation target, and the specific S_min、V_minWhich may be 3 meters and 100 meters/second, respectively.

In the method for determining the operation parameter correction threshold based on the navigation system, the correction threshold of the operation parameter in the next period is determined according to the operation parameter value of the current operation target and the corresponding minimum value of the correction threshold, the minimum value can be a navigation deviation caused by an initial reference error, in the embodiment, the influence of the initial reference error on the navigation deviation is considered for setting the correction threshold, the accuracy and the rationality of setting the correction threshold are improved, and the accuracy of correcting the operation track of the operation target is further improved.

As an optional implementation manner of this embodiment, the method further includes:

firstly, obtaining a maximum value of a correction threshold corresponding to an operation parameter;

for example, the setting of the maximum value of the correction threshold corresponding to the operation parameter may be obtained by counting historical operation data of the operation target, and the maximum value of the historical operation data, which is obtained by normally correcting the operation target, is used as the maximum value of the correction threshold. The maximum value of the correction threshold corresponding to the operation parameter comprises the minimum value of the visual speed correction threshold and the maximum value of the visual position correction threshold. The obtaining mode may be obtained from a memory in which the maximum value of the apparent velocity correction threshold and the maximum value of the apparent position correction threshold are stored in advance, or may be obtained directly from the external real-time input maximum value data of the correction threshold.

And secondly, taking the maximum value of the correction threshold of the operation parameter as the correction threshold of the operation parameter in the next period when the correction threshold of the operation parameter in the next correction threshold updating period is larger than the maximum value of the correction threshold of the corresponding operation parameter.

Illustratively, the specific implementation manner can be realized by the following formula:

；

；

wherein the content of the first and second substances,representing the minimum value of the apparent velocity correction threshold;indicates the maximum value of the visual velocity correction threshold, in this embodimentMay be 40 m/s;represents the apparent position minimum;indicates the maximum value of the apparent position correction threshold, in this embodimentMay be 25000 meters;indicating a visual velocity correction threshold;indicating a view position correction threshold;representing a view position of the operational target;indicating the apparent velocity of the operational objective.

It can be known from the above formula that the correction threshold values of the apparent velocity and the apparent position calculated in any correction threshold update period must be less than or equal to the maximum value of the correction threshold, and when the correction threshold values of the apparent velocity and the apparent position are greater than the maximum value, the maximum values of the correction threshold values of the apparent velocity and the apparent position are used as the correction threshold values of the apparent velocity and the apparent position.

According to the method for determining the operation parameter correction threshold based on the navigation system, the maximum value of the correction threshold limits the size of the correction threshold, so that the maximum value of the correction threshold of the operation target cannot exceed the maximum value of the correction threshold, when the amount of correction required in the correction signal exceeds the maximum value of the correction threshold, the data correction at this time can be judged to be abnormal, or the navigation system sending the correction signal fails, the correction signal is not responded, and the accuracy of the operation target in correcting the operation track is further improved.

As an optional implementation manner of this embodiment, step S101 includes:

firstly, acquiring an initial value of an operation parameter of an operation target and acquiring time from the moment of the initial value to a current update period of a correction threshold;

illustratively, when the last time the threshold updating period is corrected, the running track of the running target is corrected, and the initial value of the running parameter of the running target is set to be zero; and when the running track of the running target is not corrected in the last correction threshold updating period, taking the running parameter value of the running target corresponding to the last correction threshold updating period as the initial value of the running parameter.

Specifically, the initial value of the operation parameter of the operation target may be an accumulated value of the last correction threshold update period when the last correction threshold update period does not have the velocity and the apparent position correction; or when the last correction threshold update period has the visual speed and the visual position correction, the initial values of the visual speed and the visual position are 0. When the initial value of the operation parameter of the operation target is the accumulated value of the last correction threshold update period, the mode of the initial value of the operation parameter can be obtained by the following formula:

；

wherein, t₀Indicating the time of last correction; t is t₁Indicating the end time of the last correction threshold updating period; w is a_kThe apparent acceleration measured for the inertial component, W, represents the initial apparent velocity of the operational target.

The method for obtaining the initial viewing position may be obtained by the following formula:

；

wherein the content of the first and second substances,indicating the initial apparent position of the moving object, t₀Indicating the time of last correction; t is t₁Indicating the end of the last modified threshold update period.

The time length obtaining manner of the operation target from the time of obtaining the initial value to the current correction threshold updating period may be that when the time of obtaining the initial value is the apparent speed and the apparent position correction time, the time length is the time from the apparent speed and the apparent position correction time to the current correction threshold updating period, or when the time of obtaining the initial value is the last correction threshold updating period, the time length is the time from the last correction threshold updating period to the current correction threshold updating period, and the two correction threshold updating periods may be a fixed time length, for example, 10 milliseconds.

And secondly, determining the operation parameter value of the operation target at the current time based on the initial value of the operation parameter of the operation target and the time from the obtained initial value time to the current correction threshold updating period.

For example, based on the initial value of the operation parameter of the operation target and the time to the current update period of the correction threshold, the specific manner of determining the operation parameter value of the operation target at the current time may be obtained by the following calculation formula:

；

；

wherein the content of the first and second substances,the apparent speed of the running target at the current moment is represented;representing the apparent position of the running target at the current moment;an initial value representing the apparent velocity of the operational target;an initial value representing a apparent position of the operational target; t is t₂Indicating the time of the current modification threshold update period.

According to the operation parameter correction threshold determining method based on the navigation system, the operation parameter value of the operation target at the current time is determined through the initial value of the operation parameter of the operation target and the time from the time of obtaining the initial value to the current correction threshold updating period, and the accuracy of operation parameter value calculation is improved through accumulative calculation of the visual speed and the visual position, so that the accuracy of correction threshold calculation is improved.
