Method for establishing measurement and control communication link between aircraft and ground station

Abstract

The invention discloses a method for establishing a measurement and control communication link between an aircraft and a ground station, and aims to provide a method for establishing a communication link with high link establishment efficiency and low consumption of physical resources. The present invention is realized through the following technical solutions: the aircraft and the ground station are respectively configured with a sending end state machine and a receiving end state machine, each group of receiving and sending state machines internally stores multiple groups of link parameters that match each other, and uses the state information to perform Marking, building a response mechanism based on short frame interaction, independently completing uplink and downlink link building through status inquiry and status response; the aircraft / ground station sender state machine sends interactive short frames to the ground station / aircraft, and initiates a state based on status polling Inquiry, the ground station / aircraft parses out the received interactive short frame, and sends a state response based on status polling to the aircraft / ground station; when the aircraft / ground station receives a matching status response from the ground station / aircraft, it establishes a measurement and control communication link The uplink and downlink transmission links of the road.

Description

technical field [0001] The invention relates to a method for establishing a measurement and control communication link between an aircraft and a ground station based on state polling. Background technique [0002] With the deployment and development of ground-based and space-based aerospace and aviation systems and the continuous improvement of the research level in the field of air mobile detection, the measurement and control system is facing unprecedented challenges. At present, the research mainly focuses on the production of aircraft platforms, including the research of control systems and the research of ground base stations. There are still many problems in the field of aerospace measurement and control, which are specifically reflected as follows: [0003] 1) The progress of integrated and comprehensive networking is slow, the system is not flexible enough, expansion and reconstruction are difficult, and resource usage efficiency is low; at the same time, there is st...

Problems solved by technology

[0005] 3) Due to the strong dependence of the normal operation of the traditional navigation system on the ground station, mainly based on the ground measurement and control system and the operation control system, once the traditional satellite navigation system is separated from the support of the ground station, the entire navigation system will face a decline in service performance , or even a serious risk of paralysis

However, ground monitoring stations are faced with risks such as natural disasters, man-made sabotage, operational errors, and wartime destruction, which makes ground measurement and control stations and transportation control stations the weak link of the entire navigation system; due to the low degree of autonomy and intelligence of systems and equipment , highly dependent on operators and ground systems;

[0006] 4) The security protection capability of the system is relatively fragile

The shortcomings of the existing technology are that the information processing process is long and requires a lot of manual operations, resulting in poor system timeliness and low processing efficiency, and it is difficult to deal with some sudden problems, which cannot adapt to future aerospace systems. measurement and control needs
