The breathing current indicating method of the electronic oxygen regulator is applied to an aircraft oxygen supply control system and used for providing breathing state indication for a pilot. At present, traditional mechanical control of an oxygen regulator is developed to electronic control. Mechanical control type breathing flow indication is achieved through a float flowmeter and cannot be integrated into a modern airplane comprehensive liquid crystal display system. The invention aims to solve the problem that digital breathing flow indication cannot be realized by mechanical breathing flow indication. According to the method, working state parameters, including control mechanism opening, oxygen source pressure and mask pressure parameters, of the electronic oxygen regulator are utilized, and breathing flow indication of the electronic oxygen regulator is achieved through real-time calculation. And a new method is provided for the breathing current indication function of the electronic oxygen regulator.
本发明的电子式氧气调节器的呼吸示流方法,应用于飞机供氧控制系统,用于向飞行员提供呼吸状态指示。目前氧气调节器由传统的机械控制向电子控制发展。机械控制式的呼吸示流使用浮子流量计实现,不能融入现代飞机综合液晶显示系统中。本发明旨在解决机械式呼吸示流无法实现数字式呼吸示流的问题。所述方法利用电子式氧气调节器工作状态参数,包括控制机构开度、氧源压力、面罩压力参数,通过实时计算,实现电子式氧气调节器的呼吸示流。为电子式氧气调节器呼吸示流功能提供了新方法。
