Problems solved by technology

Each radar cycle (take 4 seconds as an example), the moving distance is about 900 meters, if the data update is interrupted for 1 cycle, when the target position is updated again after 8 seconds, the target has moved about 2 kilometers, the ATC system user The position of the target seen on the display will deviate greatly from the actual situation

Embodiment Construction

[0027] As shown in the figure, the present invention describes a radar data fan number statistical monitoring method, the method includes the following steps:

[0028] Step 1, initialize the physical port;

[0029] Step 2, obtain the standard cycle and standard sector number of the radar to be detected through the configuration file, and define the array ArrSec[] for recording sector information;

[0030] Step 3, read the physical port;

[0031] Step 4, the API function read by the port returns the CRC check result while returning the radar data frame, if the result is yes, proceed to the next step, otherwise return to step 3;

[0032] Step 5 adds time stamp information for the radar data frame;

[0033] Step 6 parses the radar data frame, and if the data frame contains fan number information, obtain the fan number value at the same time;

[0034] Step 7 judges whether the data frame contains fan number information, if so, proceed to the next step, otherwise return to step ...

Abstract

The invention discloses a method for monitoring radar data fan number statistics. The method comprises the following steps: initializing; acquiring standard period and standard fan number of radar to be detected and defining array; reading a port; returning to radar data frame and CRC verified results at the same time; adding time stamp information to the radar data frame; analyzing the radar data frame and acquiring fan number value; judging whether the data frame contains fan number information; under the condition that the data frame fan number value is smaller than a former fan number value, arranging the frame as an initial frame; updating the array of fan number information and setting an array element corresponding to the fan number as 1; examining time difference value Td between the initial frame from the time and the initial from last time; clearing array statistic data; examining the array recording the fan number information; and outputting alarm information and fan numberof the lost fan and returning to the step of clearing array statistic data. The method can ensure precision of output result of the system.

Description

technical field [0001] The invention relates to the technical field of radar data processing of an air traffic control automation system, in particular to a radar data fan number statistical monitoring method for connecting air traffic control radar information and dynamically monitoring the quality of radar data. Background technique [0002] Radar data is the main information source of the air traffic control automation system. Through the connection and processing of multiple radar data, the air situation display of the controlled airspace is formed, and the controller can grasp the status of each batch of aircraft in the airspace at the control seat of the system. Flight dynamics and flight parameters, through ground-air communication equipment, implement air traffic control and coordinate command. [0003] Due to different technical systems and different manufacturers of radar equipment, there are many radar programs. Therefore, the radar information connected to each d...
