Embodiment 1

[0033] A long-endurance large-scale flight test multi-station relay measurement and control system, such as figure 1 As shown, it includes a packet receiving module, a status evaluation module, a site switching module and a data forwarding module;

[0034] The packet receiving module is used to receive the telemetry data packet, judge the data packet type from the PDXP header information flag bit of the telemetry data packet, send the angle measurement data packet in the telemetry data packet to the state evaluation module, and send the remote control data packet in the telemetry data packet Send to the data forwarding module;

[0035] The state evaluation module stores the latest telemetry data packets and angle measurement data packets arriving at each station in memory, as well as their receiving time t TM and t Angle ;Set the timer, whose period is T; after the timer is started, it starts to evaluate the status of each site, and the evaluation time is recorded as t, if t...

Embodiment 2

[0053] As shown in the figure, there are two measurement and control stations in a certain test. The measurement and control station 1 is close to the aircraft take-off site, and the measurement and control station 2 is below the airborne section of the aircraft. In this test, a total of two automatic master and slave station switching were carried out, and the process is as follows:

[0054] 1. After the aircraft takes off, the measurement and control station 1 receives the data as the master station, and the score gradually rises to 90 points. At this time, the aircraft has not yet entered the range of action of the measurement and control station 2, and the measurement and control station 2 has a score of 0.

[0055] 2. The aircraft continues to fly and reaches the airspace. At this time, the measurement and control station 2 starts to receive data, and the score gradually increases and finally reaches 90 points. As the aircraft flies away from the TT&C station 1, the score...

Abstract

The invention relates to the field of aircraft measurement and control, and proposes a long-endurance large-scale flight test multi-station relay measurement and control system and method. The system includes a packet receiving module, a state evaluation module, a site switching module and a data forwarding module; The telemetry data packet and the angle measurement data packet of the station, from which the link information is extracted to realize the real-time evaluation of the status of each measurement and control station on the ground. According to the status evaluation results of each station, the station switching is performed manually or automatically, so as to realize the fast switching of the link and ensure the normal operation of the measurement and control link during the whole test process.

Description

technical field [0001] The invention relates to the field of aircraft measurement and control, and proposes a multi-station relay measurement and control system and method for long-endurance and large-scale flight tests. Background technique [0002] In the flight test of the aircraft, the communication between the aircraft and the ground is realized through the wireless link of telemetry and remote control. During the flight of the aircraft, the distance between the aircraft and the measurement and control station may exceed the range of the telemetry link of the measurement and control station, the pitch angle of the aircraft relative to the measurement and control station is too low, and the reliability of the single station is not high. In order to ensure the normal operation of the measurement and control link throughout the test , it is necessary to carry out multi-station relay measurement and control. Different measurement and control stations are used at different ...
