Hyperbaric oxygen chamber remote fault diagnosis and operation and maintenance method and system based on Internet of things

Abstract

The invention discloses a hyperbaric oxygen chamber remote fault diagnosis and operation and maintenance method and system based on Internet of things. The method comprises the steps of obtaining a cloud source signal of a hyperbaric oxygen chamber; performing morphological filtering corrosion operation and then expansion operation on the cloud source signal, and filtering out positive pulse noiseof the cloud source signal; performing morphological filtering expansion operation and then corrosion operation on the cloud source signal, and filtering out negative pulse noise of the cloud sourcesignal; obtaining a cloud source signal mean value after the positive pulse noise and the negative pulse noise are filtered out; filtering out random noise of the cloud source signal by utilizing singular value decomposition, and reserving a characteristic singular value of the cloud source signal through ensemble empirical mode decomposition; and performing fault positioning on the hyperbaric oxygen chamber by utilizing a fault tree, training a hyperbaric oxygen chamber fault classifier through a convolutional self-encoder, and performing diagnosis and operation and maintenance on faults of the hyperbaric oxygen chamber through the hyperbaric oxygen chamber fault classifier. According to the method, the fault problem occurring in the use process of the hyperbaric oxygen chamber can be found in time, the maintenance efficiency of the hyperbaric oxygen chamber is improved, and the safety of patients and medical staff is guaranteed.

Description

technical field [0001] The invention relates to a hyperbaric oxygen chamber remote fault diagnosis and operation and maintenance method and system based on the Internet of Things, belonging to the technical field of hyperbaric oxygen chamber remote fault diagnosis. Background technique [0002] The hyperbaric oxygen chamber has become an important medical tool. Faults in the cabin, console, and oxygen supply and exhaust of the hyperbaric oxygen chamber often occur, resulting in its inability to be used normally and negatively affecting hyperbaric oxygen therapy. The treatment mechanism of hyperbaric oxygen determines that the treatment cabin of the hyperbaric oxygen chamber is a special manned pressure vessel, which requires relevant workers not only to understand the precautions of conventional pressure vessels, but also relevant manufacturers to understand the manned pressure vessels. This special pressure vessel has higher status monitoring and fault diagnosis capabilitie...

Problems solved by technology

[0003] The hyperbaric oxygen chamber is prone to leakage of the oxygen supply pipeline, internal leakage of the pressure reducing valve, or oxygen exhaust valve, inaccurate adjustment or calibration of the parts of the oxygen meter, bending of the valve core lever of the breathing regulator, and valve core sealant. Pad failure, oxygen pressure reducer bottom valve leakage and other failures, each failure will endanger the lives of patients and medical staff, so it is necessary to study the real-time fault diagnosis and digital operation and maintenance technology of intelligent hyperbaric oxygen chamber in the cloud

At this stage, if the medical equipment in the hyperbaric oxygen chamber is faulty or damaged during use, it is mainly to eliminate the faults one by one manually, and it is difficult to find the problem effectively and quickly. There are many vulnerable parts of the oxygen chamber equipment, such as If the replacement is not timely, it will affect the treatment effect of the oxygen chamber, and even cause serious medical accidents
