Problems solved by technology

However, if the start and stop positions of the valves of the nitrogen filling vehicle are abnormal or the air gauge is damaged, the operator will have no way of judging the working status, which will lead to serious operational accidents
Moreover, artificial faults are not allowed in actual production, and informal operations are generally not allowed. It shows that they do not understand the phenomenon of abnormal work, so they cannot train the experience of correct handling of emergencies

Embodiment Construction

[0026] Such as figure 1 As shown, the gas circuit system of the aviation nitrogen charging vehicle consists of high-pressure gas cylinders, diaphragm compressors, pipelines, refill valves, supply valves, inflation valves, deflation valves, barometers, safety valves, check valves, and pressure reducing valves. , a pressure regulating valve, an air inlet nozzle, etc.

[0027] The equivalent rules of the above gas system and electrical system are studied as follows:

[0028] 1). The gas cylinder equivalent in the high-pressure gas cylinder pipeline network system corresponds to the capacitor in the circuit topology: the pressure of the gas cylinder corresponds to the capacitor voltage; the gas volume of the gas cylinder corresponds to the capacitor charge; the air flow of the gas cylinder corresponds to the capacitor current; capacitance.

[0029] 2). Pipeline flow resistance is equivalent to corresponding circuit resistance.

[0030] 3). The gas path topology is equivalent to...

Abstract

The invention discloses an aviation nitrogen-filling vehicle gas circuit system dynamic electric simulation method and device. A gas cylinder pipeline network is converted into a dynamic circuit topology by using the equivalent corresponding relation of a gas circuit system and an electric system. By using the aviation nitrogen-filling vehicle electric simulation method and device, an initial gascylinder pressure value can be set, and then the gas-filling flow of a nitrogen-filling vehicle can be dynamically simulated by only acquiring the state of each switch valve. The method and device provided by the invention have practical value and significance for an operator to well know the gas-filling flow of the nitro-filling vehicle, understand the working principle of each flow, practice the adaptability of the operator to sudden accident and locate and analyze the fault.

Description

Technical field: [0001] The invention relates to a dynamic simulation device and method, in particular to a dynamic electrical simulation method and device for the gas circuit system of an aviation nitrogen-charging vehicle. Background technique: [0002] With the continuous development of modern aviation technology and aviation weaponry, nitrogen and oxygen have been widely used in civil and military aircraft flight and ground maintenance support. According to my country's current flight support system, nitrogen and oxygen for flight are mainly produced by ground oxygen and nitrogen production equipment and stored in gas cylinders. Before flight, oxygen and nitrogen charging vehicles are used to fill aircraft cylinders for backup. [0003] As the main equipment on the ground of the airport, the nitrogen-filled vehicle has a direct impact on the quality of supply guarantee and flight safety. At the same time, the technical proficiency of operators plays a decisive role in a...
