A Realization Method of Cooperative Target Control in Calibration Flight Route

Abstract

The invention relates to a method for implementing cooperative target control in a calibration flight airway. The method comprises the following steps of: S1, carrying out scheme fiction on a system by adopting a hierarchical design concept, wherein a protocol conversion case is a primary control object and takes charge of distinguishing power-on power-off and mode switching instructions and distributing the power-on power-off and mode switching instructions to a power supply control case or a cooperative target, the power supply control case or the cooperative target is a secondary control object, the power supply control case completes relay control according to the instruction, and the cooperative target receives the mode switching instruction to complete mode switching; and S2, carrying out data frame design by adopting a cut-off control protocol, carrying out data frame judgment according to a data length, distinguishing a control mode according to a functional code, distinguishing a serial port number according to an address code, and sending out an object protocol frame by a designated serial port, wherein an object feedback frame is a data frame fed back by a responder or a Modbus device.

Description

technical field [0001] The invention relates to a method for realizing cooperative target control in flight calibration routes. It belongs to the technical field of control engineering. Background technique [0002] For the roadbed or sea-based measurement and control system, after the upgrade and transformation of the measurement and control equipment, etc., the regular inspection of the whole system is generally carried out by means of calibration flight technology. The so-called calibration flight is to assemble cooperative targets (transponders, etc.) on the aircraft, the aircraft will fly according to the predetermined flight path, the measurement and control equipment will track the targets on the aircraft, and the on-board accuracy identification and tracking parameters of the measurement and control system will be processed to complete the performance inspection or accuracy analysis. Thereby improving the orbit determination accuracy in the task. In the calibration...

AI Technical Summary

Problems solved by technology

In the calibration flight of the sea-based measurement and control system, since the measurement and control equipment covers multiple frequency bands, and each frequency band has multiple working modes that need to be identified, there are many cooperation targets on the aircraft, which brings great difficulties to installation and control; especially before flight The working mode of the cooperation target is set, and it cannot be changed during the school flight route. As a result, even if a certain mode meets the data volume requirements, the mode can only be changed in the next sortie, resulting in a great waste of resources

In order to reduce the number of cooperation targets and improve the reliability of the system, when the cooperation target can achieve mode control, the original method of adding power to a single control device is no longer suitable for the needs of school flight, and it is urgent to provide a method that can According to the needs, the cooperative target mode is switched to improve flight utilization and save flight consumption
