Abstract

The invention provides an air path control method and system for a train tail detection platform, and relates to the technical field of equipment control, and the method comprises the steps: closing all valves in the train tail detection platform, and inflating an air cylinder of the train tail detection platform through an air compressor, so as to enable the air pressure in the air cylinder to reach a first preset pressure; the proportional valve is sequentially adjusted to all preset opening and closing degrees, working parameters of the train tail detection table under the condition that the proportional valve is at all the preset opening and closing degrees are determined, and the opening and closing degrees are used for controlling target pressure when gas in the air cylinder flows to an air outlet of the train tail detection table; and the proportional valve is adjusted to the target opening and closing degree, the air outlet valve in the train tail detection table is opened, the exhaust flow of the train tail detection table is determined, and the technical problem that an existing train tail detection table consumes long time when testing the air pressure is solved.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a gas circuit control method and system for a column tail detection station. Background technique [0002] In the existing technology, the iron standard TB / T2973-2006 stipulates that the detection platform of the main engine at the end of the column should have the pressure division accuracy of 400kPa, 500kPa, and 600kPa for detecting the main engine at the end of the column and the function of detecting wind pressure and undervoltage alarm. The current general process in the industry is as follows: [0003] The air compressor of the test station is working, the cylinder pressure is increased to 400kPa, the air compressor stops working, and the air pressure accuracy of the main engine at the end of the row is tested; [0004] Check the work of the air compressor, increase the cylinder pressure to 500kPa, and check the air pressure accuracy of the main engine at the end ...
