The working principle and the beneficial effects of the technical scheme are as follows: in the using process of the respirator, the pressure sensors of the controller work in real time, the horizontal average stress and the longitudinal average stress of the joint of each pipe joint and the electric device plug are calculated based on the detection values of the pressure sensors and the formulas (1) and (2), friction factors are removed when the horizontal average stress is calculated, the pressure sensors are arranged at different positions of the joint of the pipe joint and the electric device plug of the respirator, and only a single point is prevented from being detected by arranging the pressure sensors at the different positions, so that the pressure detection value is more reliable;
the controller compares the horizontal average stress of the butt joint of each pipe joint or electric device plug with a corresponding horizontal stress reference value, and compares the longitudinal average stress of the butt joint of each pipe joint or electric device plug with a corresponding longitudinal stress reference value, when the horizontal average stress of the butt joint of each pipe joint or electric device plug is greater than or equal to the corresponding horizontal stress reference value and/or the longitudinal average stress of the butt joint of each pipe joint or electric device plug is greater than or equal to the corresponding longitudinal stress reference value, the controller controls the first alarm to give an alarm and controls the display to display the horizontal average stress and the longitudinal average stress, otherwise, the alarm is not given;
the alarm device can reliably alarm when the butt joint of each pipe joint or electric device plug is horizontal (caused by excessive dragging tension) and longitudinal stress is abnormal (caused by artificial misstep or placement of heavy objects at the butt joint of the pipe joints or electric device plugs).
In the using process of the respirator, when the first alarm does not give an alarm, the controller controls the camera device to periodically work, an image of a space area where the respirator is located is obtained and transmitted to the controller, the controller transmits the risk image to the image processing device, the image processing device obtains the risk image and the corresponding risk level based on the memory, the image processing device compares the image of the space area where the respirator is located with the risk image, obtains the similarity between the image of the space area where the respirator is located and the risk image, and transmits the similarity and the risk level to the controller; the controller calculates a comprehensive risk assessment value through a formula (3) based on the similarity and the risk level; and the controller compares the comprehensive risk assessment value with a preset comprehensive risk reference value, and when the comprehensive risk assessment value is greater than or equal to the preset comprehensive risk reference value, the controller controls the second alarm to give an alarm and displays the comprehensive risk assessment value and an image of a space area where the breathing machine is located through a display. The risk image factors, the horizontal stress factor and the longitudinal stress factor of the butt joint of the pipe joint or the electric device plug are comprehensively considered in the formula (3), so that the defect of misjudgment due to the fact that only a single factor is considered is overcome. When the alarm is given through the risk image factors, the risk images comprise different risk operation images of a human body to the breathing machine, risk images of a joint connection position of the breathing machine and risk images of a butt joint position of the electric device plug, the memory further stores risk levels corresponding to all the risk images, and the alarm is more reliable by considering the artificial misoperation risk factors, the joint connection reliability factors of the breathing machine, the connection reliability factors of the electric device plug and the setting of the risk levels and considering the multiple factors and the corresponding risk levels through the multiple types of risk images.
