The sensor and a part to be tested are placed in the temperature test box. The sensor is connected with the part to be tested. The output end of the sensor is connected with the input end of the temperature and strain data acquisition device. The output end of the temperature and strain data acquisition device is connected with the input end of the temperature test box through the thermostat drive control interface. According to the utility model, stress and temperature change process data in a temperature test process are provided, which is convenient for the comparison with simulation data; temperature reliability design is modified; stress can be monitored in real time; and if a failure event point is found, the temperature test is instantly stopped and test personnel are notified, thus the test time and the device loss are saved.
Description
Technical field
The utility model relates to a kind of environment temperature and tests the comprehensive control system.
Background technology
The environmental reliability of instrument and equipment is the focus that industry is paid close attention to as the key factor of properties of product quality always, has taked a large amount of technological means to guarantee the realization of product reliability.For the influence of ambient temperature, existing common practice is to be experimental facilities with the temperature test chamber, and Inside Air Temperature and humidity are controlled at desired value, be maintained fixed the time, take out then, whether the equipment of seeing can normally move, or whether checkout facility has the position of damage.
Existing humid test measuring means in carrying out process of the test, can't be found out the STRESS VARIATION of test specimen to be measured surface and temperature correlation to test serviceability differentiation later, can't contrast with design of Simulation and then the change reliability design.In addition, if can in time monitor and destroy the STRESS VARIATION that takes place, then can shorten test period, reduce the testing equipment loss.
Summary of the invention
The purpose of this utility model is to provide a kind of environment temperature to test the comprehensive control system.
The environment temperature test comprehensive control system that the utility model proposes, form by temperature test chamber 1, sensor 2, temperature, strain data collecting device 3 and incubator drive controlling interface 4, wherein: place sensor 2 and test specimen to be measured in the temperature test chamber 1, sensor 2 connects test specimen to be measured, the output terminal of sensor 2 connects the input end of temperature, strain data collecting device 3, and the output terminal of temperature, strain data collecting device 3 connects the input end of temperature test chamber 1 by incubator drive controlling interface 4.
In the utility model, described sensor 2 adopts temperature and strain transducer.
The course of work of the present utility model is as follows:
Lay test specimen to be measured in temperature test chamber 1 inside, and placement sensor and test specimen to be measured.After on-test, by sensor acquisition, record and monitor temperature signal and strain signal.Simultaneous temperature, strain data collecting device 3 and temperature test chamber 1 are connected with digital port, close down temperature test chamber after signal numerical value transfinites.Wherein: adopt the data acquisition of many physical quantity signals to finish to temperature and strain signal.
The beneficial effects of the utility model are:
1. provide in the humid test process, the data of stress and temperature changing process, convenient and emulated data compares, and revises the temperature reliability design;
2. but counter stress is monitored in real time, finds the destructive insident point, stops humid test immediately, and the notice testing crew, saves test period and equipment loss.
