Digitalized bunched cable combustion test device based on computer automatic control

Abstract

The invention relates to a digitalized bunched cable combustion test device based on computer automatic control. The device comprises a test box, an electric control cabinet, and a power supply. The electric control cabinet is provided with a gas regulating valve, an air regulating valve, a gas flowmeter, an air flowmeter, a gas pressure gauge, an air pressure gauge, a display instrument for temperature inside the box, an environmental humidity display instrument, and an electronic micro anemometer. The device is characterized in that: it additionally includes a computer equipped with control software, and a time display controller; the gas flowmeter, the air flowmeter, the gas pressure gauge, the air pressure gauge, the display instrument for temperature inside the box, the environmental humidity display instrument, the electronic micro anemometer, and the time display controller are respectively provided with a data communication interface and are in communication connection with a computer through respective data communication interface; the gas regulating valve and the air regulating valve are both electric control valves and respectively act according to control signals output from the computer. The computer of the device realizes automatic control of a test process, improves test accuracy, and can store test data.

Description

technical field [0001] The invention relates to a combustion test device, in particular to a cable bundle combustion test device. Background technique [0002] At present, the devices used for the cable bundle combustion test mainly include a test box and an electrical control cabinet. During the test, the test situation was observed through the observation window on the test box. The observation was laborious and easily affected by human factors, resulting in a large difference in the observation results; the flow meter and other measuring devices on the electrical control cabinet were not easy to observe; and the data of the combustion process could not be saved, data, so the history cannot be found. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a computer-based automatic control cable bundling combustion test device, which realizes automatic control and can st...
