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

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 communication link establishment method which is high in link establishment efficiency and low in physical resource consumption. The invention is realized through the following technical scheme: the method comprises the following steps: an aircraft and a ground station are respectively configured with a sending end state machine and a receiving end state machine, a plurality of groups of mutually matched link parameters are stored in each group of receiving and sending state machines, marking is carried out by utilizing state information; a response mechanism is constructed based on short frame interaction, and uplink and downlink link establishment is independently completed through a state inquiry and state response mode; the aircraft / ground station sending end state machine sends an interaction short frame to the ground station / aircraft and initiates state inquiry based on state polling, and the ground station / aircraft analyzes the received interaction short frame and carries out state response based on state polling to the aircraft / ground station; and when the aircraft / ground station receives the matching state response from the ground station / aircraft, uplink and downlink transmission links of the measurement and control communication link are established.

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. [0002] technical background [0003] 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: [0004] 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, the...

Problems solved by technology

[0006] 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;

[0007] 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
