Abstract

A high-temperature test control method of the present invention comprises the following steps of a setting the condition data and starting to test, wherein the condition data is correlated with the test conditions; b acquiring the test data during a test process, wherein the test data is corresponding to the condition data; c determining whether the condition data and the test data match, if the condition data and the test data do not match, executing a step d, and if the condition data and the test data match, executing a step e; d adjusting the equipment parameters to enable the test data and the condition data to match, wherein the equipment parameters are correlated with a plurality of parts of a high-temperature test device; e acquiring the result data of a test member. According to the control method provided by the present invention, the test control parameters can be adjusted timely, and the test results according with the standards are obtained.

Description

technical field [0001] The invention relates to the field of high temperature tests, in particular to a high temperature test control method and system. Background technique [0002] The main purpose of the research on the fire resistance of building structures is to evaluate the impact of fire on the structure, the degree of damage, and the fire resistance limit of the structure, and to provide a basis for the design of structural fire protection and the reinforcement and repair of fire structures. There are basically three methods, including theoretical analysis, numerical simulation and Experimental Research. Experimental research provides verifiable data for theoretical analysis and numerical simulation, and in many cases it is difficult to completely simulate actual fires. The reliability of experimental research is high, but the cost is high, and the requirements for the control and testing system of the equipment are high. [0003] The current high-temperature furna...

Problems solved by technology

In the test process of open flame combustion heating, the control of heating rate, load loading and furnace pressure will all affect the test results. Although the heating curve and load loading curve can be preset before starting the test, it is subject to the test conditions. The temperature and load in the actual test cannot be carried out according to the predetermined idealized conditions.

[0004] In addition, in the actual experiment process, on the one hand, the furnace wall of the high-temperature furnace will reflect heat to the test piece after heating, resulting in an increase in the temperature of the test piece; on the other hand, due to the large volume of the test piece, the test piece itself will accumulate a certain heat

Therefore, there is a gap between the rising trend of the air temperature in the high-temperature furnace and the rising trend of the temperature of the test piece itself.

In the prior art, the actual test temperature is obtained by collecting the air temperature in the high-temperature furnace, and the actual test temperature obtained in this way cannot accurately reflect the temperature change of the test piece itself.
