Description

Technical Field

[0001] The invention relates to the technical field of remote control, and in particular to an aging test remote control system. Background Art

[0002] With the rapid development of modern industry, product aging and failure have become important factors affecting production efficiency and safety. Product aging test is to accelerate the aging of products under certain conditions to understand the technical indicators of product reliability, durability and life span, and ensure the performance of products under normal use environment. Traditional aging test usually adopts manual monitoring and data recording, which is inefficient and inaccurate, and prone to data recording errors, interference during the test process and other problems.

[0003] With the advancement of information technology, aging tests can be remotely controlled through sensors and communication networks. The existing patent with authorization announcement number CN207488263U proposes an intelligent remote control system for an aging test chamber, including an aging test chamber with an observation window, a camera for photographing test samples, a shutter trigger connected to the camera, a central controller, a network connector and a remote terminal. The central controller controls the shutter trigger and receives photos taken by the camera. The network connector is connected to the central controller. The remote terminal sends a photo command to the central controller through the network connector and receives photos sent by the central controller, thereby realizing remote control of the camera to take photos to observe and record the aging test status, effectively reducing the labor intensity of workers.

[0004] The prior art only takes photos by remotely controlling the camera and observes the photos to record the aging status, and does not involve the parameter adjustment of the aging test chamber. Since the records of the aging test are time-series, the prior art does not consider the problem of disordered data received by the remote terminal due to network delays or congestion.
