Method and system for remote fault diagnosis and operation and maintenance of hyperbaric oxygen chamber based on Internet of Things

Abstract

The invention discloses a method and system for remote fault diagnosis and operation and maintenance of a hyperbaric oxygen chamber based on the Internet of Things, and obtains a cloud source signal of a hyperbaric oxygen chamber; for the cloud source signal, the corrosion operation of the form filter and then the expansion operation are performed to filter out the positive value of the cloud source signal Impulse noise; the expansion operation of the cloud source signal first and then the corrosion operation to filter out the negative pulse noise of the cloud source signal; obtain the mean value of the cloud source signal after filtering the positive pulse noise and negative pulse noise; use singular value decomposition to filter out For the random noise of the cloud source signal, the characteristic singular value of the cloud source signal is retained by ensemble empirical mode decomposition; the fault tree is used to locate the fault of the hyperbaric oxygen chamber, and the hyperbaric oxygen chamber fault classifier is trained by the convolutional autoencoder; The cabin fault classifier diagnoses and maintains the faults of the hyperbaric oxygen chamber. The invention can timely discover the failure problems occurring during the use of the hyperbaric oxygen chamber, improve the maintenance efficiency of the hyperbaric oxygen chamber, and ensure the safety of patients and medical staff.

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...

AI Technical Summary

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
