[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the present invention provides a signal receiving method and a receiver in a high dynamic environment, which solve the above-mentioned problems.

[0005] (II) Technical solution

[0006] To achieve the above object, the present invention provides the following technical solution: a signal receiving method in a high dynamic environment, specifically comprising the following steps:

[0007] Step 1: Mobile setting: A positioning system is installed on the data positioning terminal to obtain the location information of the data positioning terminal. Then, the current location of the data positioning terminal is taken as the sphere center, the time information sent by the satellite is received, and after time synchronization, a timestamp signal containing the moving speed information of the data positioning terminal is sent to the receiving and analysis system as a reference signal. Then, the reference signal interval transmission radius is set, and the reference signal sending position is taken as the sphere center to form a spherical environment. When the data positioning terminal moves out of the spherical environment, a reference signal is sent again. As the data positioning terminal moves, several spherical environments are formed;

[0008] Step 2, signal reception: The receiving and analyzing system captures the reference signal sent by the data positioning end. After capturing a reference signal, the location of the reference signal is set as the sphere center, and the reference signal interval transmission radius is set to form a search spherical environment. The next reference signal and satellite AC signal are searched in the search spherical environment. After obtaining several reference signals, the satellite AC signal is detected, and then the satellite AC signal is obtained in the search spherical environment;

[0009] Step 3, analysis and adjustment: according to the reference signals obtained in step 2, the reference signals are sorted in order according to time, and the moving route of the signal receiving end is generated; according to the sending time of the satellite AC signal and the signal receiving time of the receiving analysis system in step 2, the time difference between the two is calculated; after obtaining multiple groups of time difference data, the maximum and minimum values ​​are removed, the average value is calculated, and the delay time value of the signal reception in the spherical environment is obtained; according to the spacing between two adjacent reference signals in the moving route and the time difference of signal transmission, the average speed of the data positioning end is calculated; the delay time value of the data positioning end in the same spherical environment is multiplied by the average speed to obtain the delay distance value; after setting the error distance value, it is added to the error distance value as the reference signal interval transmission radius under the corresponding average speed; when the data positioning end moves, according to the speed information in the reference signal obtained in step 2, the reference signal interval transmission radius set in step 1 is replaced; the operations of steps 1, 2 and 3 are repeated to obtain the satellite AC signal.

[0010] By adopting the above technical solution and utilizing the construction of reference signals and a spherical environment, a large amount of data is provided for the receiver to collect signals. The establishment of a spherical environment effectively reduces the receiver's retrieval area for reference signals and satellite communication signals, so that once the receiver receives the reference signal, it can track and receive the satellite communication signal. This makes it easy to use and can ensure effective signal communication in a high dynamic environment.

[0011] The present invention is further configured as follows: the data positioning terminal includes a GPS positioning module and a matching synchronization unit, the GPS positioning module and the matching synchronization unit are connected, wherein the GPS positioning module is used to collect the position coordinate information of the mobile terminal, and the matching synchronization unit includes a time synchronization module, an information recording module, a radius setting module and a timestamp generation module;

[0012] The time synchronization module is used to receive time information sent by the satellite and perform time synchronization;

[0013] The information recording module is used to record the position coordinate information and moving speed information of the data positioning end;

[0014] The radius setting module is used to set the reference signal interval transmission radius with the current position of the data positioning end as the sphere center to form a spherical environment;

[0015] The timestamp generation module is used to send a timestamp signal including the current moving speed of the data positioning terminal, the current position coordinate information, the real-time speed information in the spherical environment that has been left, and the average speed of movement in the next spherical environment to the data positioning terminal as a reference signal.

[0016] By adopting the above technical solution and using the time matching method, time synchronization is ensured while providing accurate protection for the time information in the reference signal, ensuring the accurate and effective calculation of the delay time value, and thus providing protection for the setting of the reference signal interval transmission radius.

[0017] The present invention also discloses a receiver, including a receiving and analyzing system, wherein the receiving and analyzing system includes a data positioning terminal, a signal receiving unit and an analyzing and adjusting unit, and the signal receiving unit is connected to the data positioning terminal and the analyzing and adjusting unit respectively.

[0018] The present invention is further configured as follows: the signal receiving unit comprises a fixed-point ring detection module and a signal capture module, the fixed-point ring detection module and the signal capture module are connected, the fixed-point ring detection module is used to capture a reference signal at the signal receiving end, set the position of the reference signal as the sphere center, set the reference signal interval transmission radius to form a search spherical environment, and search for the next reference signal in the search spherical environment;

[0019] The signal acquisition module is used to detect satellite AC signals in a detection spherical environment.

[0020] By adopting the above technical solution, after the receiver receives a reference signal, the reference signal and the AC signal in the search spherical environment can be quickly collected through the setting of the search spherical environment.

[0021] Furthermore, after performing a reference signal inspection, the next reference signal inspection is performed at the edge of the inspection spherical environment, thereby realizing a rapid inspection of the reference signal.

[0023] The delay determination module is used to obtain the time difference between the AC signal sending time in the data positioning terminal and the signal receiving time of the receiving analysis system, and after obtaining multiple groups of time difference data, remove the maximum and minimum values, calculate the average value, and obtain the delay time value in the spherical environment;

[0024] The speed analysis module is used to calculate the average speed of the data positioning terminal according to the distance between two adjacent reference signals in the moving route and the time difference of signal transmission;

[0025] The radius adjustment module is used to multiply the delay time value and the average speed of the data positioning end in the same spherical environment to obtain a delay distance value, set the error distance value, and add the error distance value to use it as the reference signal interval transmission radius under the corresponding average speed. When the data positioning end moves, the reference signal interval transmission radius set in step one is replaced according to the speed information in the reference signal.

[0026] By adopting the above technical solution, the reference signal interval emission radius is formulated under different average speeds through the coordination of average speed, delay time value, delay distance value and error distance value, thereby forming a spherical environment with different radii, reducing the search range while further improving the signal detection efficiency and accuracy.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] See also Figure 1-5 The embodiment of the present invention provides a technical solution: a signal receiving method in a high dynamic environment, specifically comprising the following steps:

[0041] Step 1, movement setting: the time synchronization module 4 receives the time information sent by the satellite. After time synchronization, the GPS positioning module 2 collects the position coordinate information of the receiver. The information recording module 5 records the position coordinate information and movement speed information of the receiver. The radius setting module 6 takes the current position of the receiver as the center of the sphere and sets the reference signal interval transmission radius to form a spherical environment, wherein the reference signal is a timestamp signal including the current movement speed of the receiver, the current position coordinate information, the real-time speed information in the spherical environment that has been left, and the average speed of the movement in the next spherical environment. The timestamp generation module 7 sends the reference signal to the receiving analysis system 8. When the receiver moves out of the spherical environment, the timestamp generation module 7 sends the reference signal again. As the receiver moves, several spherical environments are formed;

[0042] Step 2, signal reception: The signal capture module 12 captures the reference signal sent by the receiver. After capturing a reference signal, the fixed-point ring inspection module 11 sets the position of the reference signal as the sphere center and forms a search spherical environment with the setting of the reference signal interval transmission radius. The signal capture module 12 searches for the next reference signal and the satellite AC signal in the search spherical environment. After obtaining several reference signals, the signal capture module 12 searches for the satellite AC signal and then receives the satellite AC signal in the search spherical environment.

[0043] Step 3, analysis and adjustment: According to the reference signals obtained in step 2, the route generation module 13 arranges the reference signals in order according to the time sequence to generate the moving route of the receiver. The delay determination module 14 obtains the time difference between the sending time of the AC signal and the signal receiving time of the signal receiving end according to step 2. After obtaining multiple groups of time difference data, the maximum and minimum values ​​are removed, and the average value is obtained to obtain the delay time value of the receiver in the spherical environment. The speed analysis module 15 calculates the average speed of the receiver according to the distance between two adjacent reference signals in the moving route and the time difference of signal transmission. The radius adjustment module 16 adjusts the receiver The delay time value and the average speed in the same spherical environment are multiplied to obtain the delay distance value. After setting the error distance value, the delay distance value is added to the error distance value to serve as the reference signal interval transmission radius at the corresponding average speed, wherein the error distance value is used as the standard value, i.e., to ensure that the reference signal interval transmission radius at the corresponding average speed can be used within the effective error range. By adjusting the size of the standard value, the recognition efficiency and recognition accuracy can be adjusted. When the receiver moves, the reference signal interval transmission radius set in step one is replaced according to the speed information in the reference signal obtained in step two, and steps one, two and three are repeated to obtain the AC signal.

[0044] As a detailed description, when only the moving route information of the receiver needs to be obtained, the error distance value is infinitely reduced, or even directly reduced to zero. At this time, the transmission frequency of the reference signal is increased, thereby making the moving route of the receiver more accurately depicted.
