Integrated control system and method for environmental testing chamber

Abstract

An integrated controller for an environmental testing system simultaneously controls and synchronizes vibration, temperature, and humidity in an environment test chamber over a specified reliability test duration, and performs condition-based measurement and processing of vibration data obtained from the environment test chamber for one or more specified trigger conditions. The controller executes a combined run schedule using a single internal clock and a hardware processor, to generate parameter control commands for the environment test chamber that remain synchronized to the single internal clock over the duration of a test, even one that lasts for weeks or months. This permits multi-variate processing of measured instantaneous values of temperature, humidity, and vibration to obtain, e.g., condition-dependent vibration power spectra and averages for available conditions of temperature, humidity, or both.
