Embodiment 1

[0043] The present invention is realized through the following technical solutions, as figure 1 As shown, the automatic lung oxygen regulator test system includes a data processing control system, a simulated lung system, a data processing control system, a simulated lung system, a simulated altitude system with a vacuum chamber, and is installed in the vacuum chamber and is compatible with the simulated The simulated mask connected to the lung system, the oxygen regulator installed in the vacuum chamber and connected to the simulated mask, the oxygen source connected to the oxygen regulator, and the data acquisition system; the oxygen source passes through the oxygen regulator, simulated mask to The simulated lung system provides oxygen supply; the data processing control system is respectively connected with the simulated lung system, the oxygen source and the vacuum chamber; the data acquisition system respectively collects data from the simulated lung system, the oxygen sou...

Embodiment 2

[0051] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 , figure 2 As shown, the simulated lung system includes a cylinder 4, a joint bearing 3, an electric cylinder 2 and an electric cylinder driver 1 for driving the electric cylinder 2 to work, the electric cylinder 2 drives the cylinder 4 to work through the joint bearing 3, and the cylinder 4 are connected to simulate the connection of the mask; the cylinder 4 is a cylinder type. The breathing volume and the breathing time are in a sinusoidal relationship, and the expiratory volume or inhalation volume produced by the simulated lung system is controlled by the interface area of ​​the inner cavity of the cylinder 4 and the displacement of the piston of the cylinder 4;

[0052] The calculation formula of the expiratory volume or inspiratory volume generated by the simulated lung system is: V=P=S*L;

[0053] In the formula, S- cylinder 4 inner chamber cross-sectional area;

[00...

Embodiment 3

[0067] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, a first flowmeter and an oxygen concentration meter for collecting oxygen partial pressure values ​​are also arranged between the simulated mask and the cylinder 4, and the simulated mask is connected to the cylinder 4 through the first flowmeter and the oxygen concentration meter in turn. ; The first flow meter and the oxygen concentration meter are respectively connected with the data acquisition system. The oxygen partial pressure value collected by the oxygen concentration meter is calculated through a formula to obtain an oxygen concentration value.

[0068] The formula for calculating the oxygen concentration value is: ω%=K / θ*100%

[0069] In the formula, K-oxygen partial pressure value collected by the oxygen concentration meter;

[0070] θ - Atmospheric pressure values ​​corresponding to different altitudes.

[0071] It should be noted that through the above...

Abstract

The present invention discloses a fully-automatic lung type oxygen regulator test system. The system comprises a data processing and control system, a simulated lung system, a simulated altitude system provided with a vacuum chamber, a simulated mask which is mounted in the vacuum chamber and is connected with the simulated lung system, an oxygen regulator which is installed in the vacuum chamber and is connected with the simulated mask, an oxygen source which is connected with the oxygen regulator and a data acquisition system; the oxygen source sequentially passes through the oxygen regulator and the simulated mask so as to supply oxygen to the simulated lung system; the data processing and control system is connected with the simulated lung system, the oxygen source and the vacuum chamber; and the data acquisition system collects data from the simulated lung system, the oxygen source and the vacuum chamber and transmits the collected data to the data processing and control system. With the fully-automatic lung type oxygen regulator test system of the invention, the oxygen supply regulator can be tested fully automatically with high efficiency, test operation being simple; a test environment provided by the system is closer to the real working environment of a product, so that test data are more reasonable.

Description

technical field [0001] The invention relates to the technical field of oxygen supply equipment testing, in particular to a full-automatic lung type oxygen regulator testing system. Background technique [0002] At present, the testing of products such as "oxygen supply regulators" in China is mainly done in a non-automatic way or according to the wearing experience of the experiencer. The non-automatic way of testing is inefficient, and the test needs to frequently adjust the valve and record the test data. , the test personnel have a lot of work content, and the test operation requires certain experience and skills; the test results of the human body wearing experience test method vary greatly with individuals, without reasonable data results as support, all based on individual feelings, and the reliability of the test results is low . Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic lung-type oxygen regulator testin...
