Thermal response test method of spacecraft assembly thermistor based on augmented reality

Abstract

The invention discloses a thermal response test method of a spacecraft assembly thermistor based on augmented reality. A thermal response test is carried out through test equipment. The method comprises steps of receiving the first feature information, and the first feature information comprising a three-dimensional model of a spacecraft, preset positions of thermistors on the spacecraft and telemetering codes, corresponding to the preset positions, of the thermistors; receiving the second feature information, wherein the second feature information is used for mapping a specific position on astructural deck of the spacecraft; generating a first indication according to the first feature information and the second feature information, wherein the first indication comprises the position of each thermistor and the path to each thermistor; displaying the first indication; and performing a thermal response test of the thermistor according to the first indication. According to the method, the position of the thermistor can be quickly positioned based on augmented reality, multi-person operation is not needed, manpower is liberated, and thermal response test efficiency of the thermistor is improved.

Description

technical field [0001] The invention generally relates to the technical field of spacecraft assembly, in particular to a thermal response testing method for a thermistor of a spacecraft assembly based on augmented reality. Background technique [0002] Thermistors are commonly used sensors for temperature telemetry signal detection on spacecraft. In the overall assembly stage of spacecraft, a large number of assembly thermistors are pasted on the spacecraft. The number of thermistors is large and widely distributed. Some are on electronic equipment, and some are on cables. After the thermistor is pasted, its leads can be welded into the low-frequency cable network on the spacecraft. After the final assembly of the spacecraft, the electrical performance test of the spacecraft is required. Before the power-on test of the spacecraft, the thermal response test of the thermistor of the spacecraft assembly is required. The thermal response test is not only a review of the correctn...

Problems solved by technology

However, due to the large number of thermistors on the spacecraft and the complex layout, after the thermistors are welded into the cable network, their leads will be bound and fixed into the cable network, and the thermistor code marks on the leads become invisible. The speed of the code name and location of the thermistor depends heavily on the operator's familiarity with the spacecraft and thermistor layout files, making testing difficult
