Problems solved by technology

Due to the current 5G network standard factors, the downlink resources are far more than the uplink resources, so the resources for carrying uplink data are limited. At the same time, the laboratory environment is complex, 5G signal transmission has much interference, and there are great difficulties in the high-speed uplink transmission of test data.

specific Embodiment approach

[0043] Taking the fatigue strength test of a large civil aircraft as an example, the specific implementation method is as follows:

[0044] Step 1: Determine the number of data sending terminal modules. For the field test environment, the number of certain data sending terminal modules can be set to 4;

[0045] Step 2: When N=4, the inclination angle of the antenna of module 1 is 0°, the inclination angle of the antenna of module 2 is 22.5°, the inclination angle of the antenna of module 3 is 45°, and the inclination angle of the antenna of module 4 is 67.5°;

[0046] Step 3: All antennas adopt directional emission technology, and the emission angle does not exceed 60°;

[0047] Step 4: The positions and angles of the antennas are evenly distributed on the sphere space where the modules are located to ensure that the distance between them is the farthest and the angle difference is the largest;

[0048] Step 5: Install 4 SIM cards in the data sending terminal, and the data ca...

Abstract

The invention belongs to the technical field of aircraft strength tests, and particularly relates to an aircraft strength test data sending terminal and sending method. The data sending terminal comprises a plurality of modules arranged in an airplane strength test environment, each module comprises two antennas, the two antennas are perpendicular to each other by adopting a dual-polarization technology, and antenna inclination angles of different modules are arranged in a mutually offset manner according to a set deviation value. The data sending method comprises the following steps: the number N of concurrent modules contained in the data sending terminal is determined according to the uplink transmission rate of aircraft strength test data; the airplane strength test data is segmented into a plurality of MTU packets, the MTU packets are identified, and identification at least comprises a splicing sequence; and uplink transmission is performed on the MTU packet through N concurrent modules. According to the invention, uplink coverage is enhanced, time delay is shortened, the problem of high-speed uplink transmission of mass data in a complex test environment is solved, and safe, reliable and high-speed wireless uplink transmission of large-scale test data can be realized.

Description

technical field [0001] The application belongs to the technical field of aircraft strength test, and in particular relates to an aircraft strength test data sending terminal and a sending method. Background technique [0002] The essence of aviation strength test is discrete data production, and a large amount of test data will be generated during the whole test process. The development goal of aviation strength test at this stage is digitization, informatization and intelligence. At the same time, in order to realize the flexibility of test equipment and facilities On-demand deployment, 5G wireless network will also be widely used in the transmission of aviation strength test data, which puts forward higher data transmission and processing requirements for aviation strength test. [0003] Different from the traditional communication network requirements, the aviation strength test will generate a large amount of test response data and test monitoring data (video monitoring,...
