Description

Shielding method, processing end and system for monitoring data source test responder

Technical Field

The invention relates to the technical field of shielding of aircrafts, in particular to a shielding method, a processing end and a system for monitoring a data source test responder.

Background

According to the configuration requirement of civil aviation air traffic control radars, each radar is provided with a test transponder (namely a fixed echo device). The device is typically mounted near a navigation terminal (or radar head) and transmits a specific signal for checking whether the radar is operating properly.

The ADS-B monitoring technology which is emerging recently makes similar configuration requirements for the ground receiving stations of the ADS-B, and each ground station is configured with a test transponder for checking whether the ground station is operating normally.

The signal emitted by the test transponder configured in the monitoring equipment is not essentially different from the signal of the normal flight target, and is particularly important for the maintenance department of the equipment. However, for regulatory bodies, the above signals have no reference to them, and may also cause visual interference in some cases. Therefore, a reliable shielding method must be provided to meet the application requirements of both the equipment maintenance unit and the regulatory user unit.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 identification information of the test transponder (SSR code for secondary radar and 24-bit address code for ADS-B) is often a specific code, but the code may be used by a common aircraft, so that it is impossible to filter or shield by simply specifying the identification information.

Meanwhile, most radars can identify the target of the test transponder through specific data bits in the data message, but some types of radars, ADS-B and other monitoring equipment cannot identify the target of the test transponder in the data message.

Based on this, the inventive concept of the invention is: the position information of the test responder is preset, the possible airspace range of the test responder is planned, and meanwhile, the filtering or shielding of the target of the test responder can be effectively realized through background data processing and variable parameter setting of a human-computer interface.

Based on the inventive concept, the embodiment of the invention provides a shielding method for monitoring a data source test responder. It should be noted that the shielding method is described with the background data processing end as the only execution main body. As shown in fig. 1, the shielding method includes:

s101, receiving data to be detected from a test target.

The data to be detected comprise a current secondary answer code, a current 24-bit address code and a current speed of the flight target.

S102, detecting the data to be detected by adopting preset shielding parameters to obtain a detection result.

The shielding parameters comprise a secondary response code, a 24-bit address code, a preset position, a position deviation range and a speed threshold value of the test responder.

When the current secondary response code or the current 24-bit address code is consistent with the shielding parameter, comparing the current position information with the preset position to obtain a current position deviation;

and if the current position deviation is within the position deviation range and the current speed is less than a speed threshold value, judging that the test target is a test responder, otherwise, judging that the test target is a common aircraft.

S103, marking the test target with the detection result of the test responder, and generating target information.

The target information comprises a marked test target and an unmarked flying target;

and S104, sending the target information to the human-computer interface display end, so that a user can shield the marked test target by operating the human-computer interface display end.

For example, the shielding method of the present embodiment mainly includes:

1. mask parameter setting

Specifically, the user operates the human-computer interface display end to set the shielding parameters, and the shielding parameters are as follows:

(1) Radar identification information: an ID number or name that uniquely identifies the process within the system;

(2) And (4) secondary response code: SSR codes for testing transponders, or

(3) 24-bit address code: 24-bit address code for S mode or ADS-B test responder;

(4) Presetting a position: the test responder presets an echo position, can be described in a polar coordinate mode or a longitude and latitude mode, and defines PO;

(5) Position deviation range: the deviation of the position of the test transponder from a preset value, due to delay of the test transponder echo signal or radar error, is defined as R.

2. Background data processing

And when the background data processing end receives and detects the target information with the secondary code or the 24-bit address code consistent with the adaptive parameter setting, the position information of the target information is compared with the preset position information, and the speed information is compared with the preset speed information. If the target is in the range of taking P0 as the center of circle and R as the radius and the speed is less than a specific value, the target is judged to be a test responder and a corresponding mark is sent to the human-computer interface end. If the above conditions cannot be met at the same time, the target should be a normal aircraft.

It should be noted that the target containing the test responder flag does not participate in alarm calculation such as short-term collision alarm, low altitude alarm, danger zone/restricted zone alarm, etc., so that false alarm can be effectively avoided and the alarm calculation amount can be reduced.

3. Human-machine interface display

When the man-machine interface display end receives the target information containing the test responder mark, the target information can be displayed as a special symbol, and the control personnel and the technical protection personnel can visually observe the target. If the control seat does not need to display the target of the test response category, a hook option of displaying/not displaying the test target is provided on the human-computer interface, and the target can be shielded.

The shielding method of the invention is implemented, the preset shielding parameters are adopted to detect the data to be detected of the test target, two results of the test target comprising the test responder and the common aircraft are obtained, and the test target corresponding to the test responder is marked, so that a user can operate the human-computer interface display end to shield the target (such as the test responder) of the test responder type, thereby effectively realizing the filtration or shielding of the test responder, effectively eliminating the normal aircraft and reducing the false alarm, and the human-computer interface can also conveniently realize the filtration or shielding of the test responder target.
