Embodiment 1

[0048] like figure 1 As shown, in this embodiment, an automatic test control system includes a controller and an altitude simulation module, a lung simulation module and a detection module respectively connected to the controller.

[0049] The altitude simulation module includes a vacuum pump motor electrically connected to the controller, a vacuum pump connected to the vacuum pump motor, and a negative pressure chamber communicated with the vacuum pump, and an oxygen supply regulator and a simulation chamber for testing are arranged in the negative pressure chamber. A face mask, the simulated face mask is in communication with the oxygen supply regulator.

[0050] The lung simulation module includes a servo motor connected to the controller and a cylinder connected to the servo motor; the cylinder is provided with a breathing hole communicated with the simulated mask through a breathing pipeline and a ventilation hole communicated with the outside world. The above-mentioned ...

Embodiment 2

[0057] On the basis of the above embodiments, in this embodiment, the negative pressure chamber is provided with a proportional valve that communicates the negative pressure chamber with the outside atmosphere. The proportional valve is mainly used to form an air inlet so that the outside gas can enter the negative pressure chamber, and the vacuum pump is used to pump the gas in the negative pressure chamber to maintain the dynamic balance of the air pressure in the negative pressure chamber, so as to realize the control of negative pressure. The gas in the chamber is replaced. Because the gas exhaled by the lung simulation module contains oxygen, if the gas in the negative pressure chamber is not ventilated, the gas in the negative pressure chamber will increase and the concentration of oxygen will increase, resulting in inaccurate experimental data. After the gas in the negative pressure chamber can be replaced by setting the proportional valve, the gas in the negative press...

Embodiment 3

[0059] On the basis of the above embodiments, in this embodiment, the oxygen supply regulator is communicated with an oxygen source, and an oxygen flow meter is arranged between the oxygen source and the oxygen supply regulator. In this way, the oxygen supply regulator can directly obtain oxygen, which makes the experimental operation more convenient. By setting the oxygen flow meter, it is convenient to detect the flow of oxygen entering the oxygen supply regulator in real time, so as to facilitate the later processing of experimental data. In this embodiment, other parts not described are the same as those in the foregoing embodiments, so details are not repeated here.

Abstract

The invention discloses an automatic test control system, which comprises a controller, and an elevation simulation module, a lung simulation module and a detection module connected with the controller respectively, wherein the elevation simulation module comprises a vacuum pump motor, a vacuum pump and a negative pressure chamber; the negative pressure chamber is internally provided with an oxygen supply regulator and a simulated mask; the lung simulation module comprises a servo motor and a cylinder; and the detection module comprises an oxygen concentration instrument arranged a respiratory tract, a respiratory flow meter arranged on the respiratory tract and a pressure sensor arranged in the negative pressure chamber. The automatic test control system has the beneficial effects that the respiratory condition of the lung and the atmospheric environment at a high altitude can be simulated, a real environment and an experiment environment for the real use condition can thus be provided, a simulated lung is used to prevent human errors caused by human factors, use effects of the oxygen supply regulator and the simulated mask can be reflected really, and the test result is more accurate.

Description

technical field [0001] The invention relates to the field of oxygen supply regulators, in particular to an automatic test control system. Background technique [0002] At present, the testing of products such as "oxygen supply regulator" in China is mainly done in a non-automatic way or according to the wearing experience of the experiencer. [0003] During the test, it is necessary to frequently adjust the valve and record the test data. The testers have a lot of work, and the test operation requires certain experience and skills; Based on individual experience, the reliability of test results is low. Resulting in low efficiency of non-automatic test bench testing. Contents of the invention [0004] The purpose of the present invention is to provide an automatic test control system, which can simulate the use of simulated lungs to simulate breathing to detect the experimental data of the oxygen supply regulator under the situation of different altitudes, can objectively...
