Description

Technical Field

[0001] The invention relates to the field of aviation technology, and in particular to an anti-load oxygen supply regulator. Background Art

[0002] When using manned centrifuges to conduct anti-G physiological training for pilots, some protective measures must be taken to prevent adverse effects caused by continuous acceleration (+Gz), especially loss of consciousness (G-LOC) caused by high continuous +Gz. The most commonly used is anti-G oxygen supply equipment, including anti-G suits, anti-G pressure regulators, oxygen supply regulators, protective helmets, pressurized oxygen supply masks, compensation vests, etc. Among them, the anti-G pressure regulator and oxygen supply regulator play the role of inflating the anti-G suit and mask and automatically adjusting the pressure value and flow rate during the +Gz process, and are key components in the anti-G oxygen supply equipment.

[0003] At present, my country's manned centrifuges use finished products of airborne oxygen systems and pilot individual protective equipment, including anti-G regulators, oxygen regulators, pressure ratio regulators, oxygen disconnectors, pressure reducers, and matching helmets, masks, anti-G suits and other equipment. In addition to anti-G and anti-G positive pressure breathing (PBG) functions, they also have functions such as high-altitude oxygen supply (PBA), which can meet the needs of pilots of certain aircraft types.

[0029] Example

[0030] The embodiment of the present invention provides an anti-g oxygen supply regulator, which is used in situations where the pressure in the anti-g oxygen supply equipment needs to be adjusted, such as Figure 1 As shown, the anti-G oxygen supply regulator is connected to the anti-G oxygen supply equipment, and the anti-G oxygen supply regulator includes: a state information acquisition module 1, a control module 2, a pressure regulation module 3 and multiple pressure regulation interfaces 4.

[0031] like Figure 1 As shown, the state information acquisition module 1 of the embodiment of the present invention is connected to the control module 2 and is used to collect the current motion state information of the manned centrifuge and send it to the control module 2.

[0032] When using a manned centrifuge to perform anti-gravity physiological training on pilots, anti-gravity oxygen supply equipment is often used to prevent adverse effects caused by the continuous acceleration of the manned centrifuge. In the embodiment of the present invention, the anti-gravity oxygen supply equipment is connected to the anti-gravity oxygen supply regulator, and the anti-gravity oxygen supply regulator is connected to different anti-gravity oxygen supply equipment (the anti-gravity oxygen supply equipment includes: anti-gravity suits, compensation vests and masks, etc.) through different pressure regulating interfaces 4. The state information acquisition module 1 adjusts the pressure in the anti-gravity oxygen supply equipment according to the current motion state information of the manned centrifuge (for example: the acceleration of the manned centrifuge, then the state information acquisition module 1 includes an acceleration sensor, this is only taken as an example but not limited to this, in practice, the current corresponding motion state information of the centrifuge is obtained according to specific needs), so as to adjust the oxygen content or air content in the anti-gravity oxygen supply equipment.

[0033] like Figure 1 As shown, the control module 2 of the embodiment of the present invention is used to send a corresponding pre-pressurization signal according to a preset anti-G oxygen supply equipment model; and send a corresponding control signal according to the current operating state information of the manned centrifuge, the preset anti-G oxygen supply equipment model and the corresponding preset threshold value;

[0034] The pressure regulating module 3 of the embodiment of the present invention is respectively connected to the control module 2, the external oxygen source and the air source, and is connected to different anti-gravity oxygen supply equipment through different pressure regulating interfaces 4. The pressure regulating module 3 is used to pre-pressurize the anti-gravity oxygen supply equipment according to the pre-pressurization signal; and adjust the oxygen content and / or air content in the anti-gravity oxygen supply equipment according to the control signal.

[0035] Since the anti-gravity oxygen supply regulator of the embodiment of the present invention can adjust the pressure in different anti-gravity oxygen supply equipment, the user selects different preset anti-gravity oxygen supply equipment models according to the anti-gravity oxygen supply equipment models worn by the pilot, and inputs them into the anti-gravity oxygen supply regulator. After that, the control module 2 sends different pre-pressurization signals to the pressure regulating module 3 according to different preset anti-gravity oxygen supply equipment models. The pressure regulating module 3 pre-pressurizes the anti-gravity oxygen supply equipment according to the pre-pressurization signals. Different pre-pressurization signals can correspond to different pressure values ​​and other information.

[0036] When the control module 2 of the embodiment of the present invention determines that the current operating status information of the manned centrifuge exceeds the corresponding preset threshold, it sends a corresponding control signal, and the pressure regulating module 3 adjusts the pressure of the connected anti-load oxygen supply equipment (that is, adjusts the oxygen content or air content in the anti-load oxygen supply equipment). For example: when the current operating status information of the manned centrifuge is the acceleration of the manned centrifuge, the preset threshold corresponding to the acceleration is the G value (G=a / g, a is the acceleration of the manned centrifuge, and g is the acceleration of gravity). When the acceleration of the manned centrifuge exceeds the G value, the control module 2 sends a control signal to the pressure regulating module 3.

[0044] Since the anti-G oxygen supply regulator of the embodiment of the present invention can be connected to different anti-G oxygen supply equipment, when the user selects a preset anti-G oxygen supply equipment model according to the model of the anti-G oxygen supply equipment worn by the pilot, the control module 2 selects different pre-charge pressure thresholds according to the preset anti-G oxygen supply equipment model, and controls the pressure regulating module 3 to pre-charge the anti-G oxygen supply equipment so that the pressure in the anti-G oxygen supply equipment reaches the pre-charge pressure threshold. In addition, the control module 2 selects different preset thresholds according to the preset anti-G oxygen supply device, and when it is determined that the current operating status information of the manned centrifuge exceeds the corresponding preset threshold, a corresponding control signal is issued, and the pressure regulating module 3 adjusts the pressure of the connected anti-G oxygen supply equipment.
