Thermal Response Test Method of Spacecraft Assembly Thermistor Based on Augmented Reality

Abstract

The present application discloses a thermal response test method for spacecraft assembly thermistors based on augmented reality. The thermal response test is performed by testing equipment, including: receiving first characteristic information, the first characteristic information includes the three-dimensional model of the spacecraft, thermal The preset position of the thermistor on the spacecraft, and the telemetry code of each preset position corresponding to the thermistor; receiving the second characteristic information, the second characteristic information is used to map the specific position on the structure deck of the spacecraft; according to The first feature information and the second feature information generate a first indication, the first indication includes the position of each thermistor and the path to each thermistor; display the first indication; perform heating of the thermistor according to the first indication Response test. The method disclosed in the present invention can quickly locate the position of the thermistor based on the augmented reality, does not require multiple people to operate, liberates manpower, and improves the thermal response test efficiency of the thermistor.

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
