The invention discloses a control method for a vibration, temperature and humidity comprehensive test device. The control method includes the steps that an acceleration sensor intermittently collects the current acceleration values of a workbench board in real time at the first collection frequency and generates acceleration induction simulation signals; a temperature sensor intermittently collects the current temperature in a temperature and humidity box in real time at the second collection frequency and generates temperature induction simulation signals; a humidity sensor intermittently collects the current humidity in the temperature and humidity box in real time at the third collection frequency and generates humidity induction simulation signals; acceleration voltage signals, temperature voltage signals and humidity voltage signals from three conditioning circuit modules are sampled and then converted into acceleration digital signals, temperature digital signals and humidity digital signals respectively through an analog-digital conversion module, and the three conditioning circuit modules are the same in sampling frequency. According to the control method for the vibration, temperature and humidity comprehensive test device, vibration control, temperature control and humidity control are integrated so that the system can be controlled comprehensively by one control system, and thus the reliability and the accuracy are improved; moreover, acceleration, temperature and humidity which are collected at different collection frequencies are displayed in one coordinate system of one displayer, and thus operation and control are facilitated.
Description
technical field [0001] The invention relates to a control method for a vibration test device, in particular to a control method for a vibration, temperature and humidity comprehensive test device. Background technique [0002] Electrodynamic vibration test bench is a kind of equipment for vibration simulation test of products or components. Through such tests, the vibration performance of a product can be evaluated, and a reasonable basis can be provided for evaluating the quality of the product. Therefore, it is widely used in aerospace, aviation, ships, etc. , automotive, electronics, communications, home appliances and instrumentation industries. [0003] The temperature and humidity chamber is mainly used to simulate the change of ambient temperature. Due to the diversity of environmental test standards, it is necessary to use the temperature control chamber and the vibration test bench together to conduct comprehensive mechanical environmental tests of temperature and v...
