BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a block diagram showing the principal features of the present invention's system and method.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

[0017] While the present invention will be described more fully hereinafter with reference to the accompanying drawings, in which an embodiment of the present invention is shown, it is to be understood at the outset of the description which follows that persons of skill in the appropriate arts may modify the invention herein described while still achieving the favorable results of this invention. Accordingly, the description which follows is to be understood as being a broad, teaching disclosure directed to persons of skill in the appropriate arts, and not as limiting upon the present invention.

[0018] Below with reference to the present invention, the FIGURES present the invention, from which one skilled in the art may deduce embodiments without getting away from the spirit of the invention.

[0019] FIG. 1 discloses the monitoring, control, and fault self-diagnosis system 30 of present invention comprising an oxygen generator 1 connected to an oxygen regulation tank 2 through an outlet valve 3 and an oxygen valve 4. The oxygen generator 1 is also connected to an air storage tank 5 via a line connector 6 containing multiple modules B, C, and D between said storage tank 5 and the oxygen generator 1. It is worth noting that in some embodiments of the invention there are multiple oxygen generators connected to the oxygen regulation tank 2 and the air storage tank 5.

[0020] An air dryer 7 is connected to the air storage system 5 through a dryer valve 8 and to an air compressor 10 via a compressor valve 11. The air compressor 10 comprising a filter (not shown) located in the inlet thereof for filtering any impurity from the atmosphere or environment. Besides, there is a cyclone filter A located between the air compressor 10 and the air dyer 7, wherein the cyclone filter A withdraws or filters oil residues. The air compressor 10 provides air from the atmosphere and pressurizes the same before transmitting said pressurized air to the air dyer 7.

[0021] The air dryer 7 withdraws the moisture from the pressurized air coming from the atmosphere maintaining a temperature equal or less than 5° C., wherein the dried air is stored in the storage tank 5. Once the dried air is inside the storage tank, the same is passed through the line connector 6, wherein there is a process of separation of oxygen which is achieved through modules B, C and D. Said modules A, B, and C contain zeolite which provides molecular sieve filtering (through a molecular sieve filter) of the nitrogen contained in the dried air and the line connector 6 provides only oxygen gas, while the nitrogen is released through an nitrogen outlet valve or a similar releasing device.

[0022] The oxygen generator 1 comprises a control and measurement system comprising digital devices for monitoring the purity of the oxygen and the flow of the oxygen gas at an outlet module controlled via a Programmable Logic Controller (PLC) running in a state detector, the PLC is connected to a A/D converter for converting analogical signal coming from different sensors positioned in the oxygen generator 1, valves 3 and 4, oxygen regulation tank 2 and different parts of system 30 to digital signals.

[0023] The PLC comprising a processor and one or more computer memory devices interoperably coupled with PLC and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers devices, perform one or more operations comprising:

[0024] a) beginning the control system;

[0025] b) entering a parameter setting process;

[0026] c) starting open only a limited number of procedures;

[0027] d) determining whether a process parameter adjustment is needed, and provide an adjustment or displaying a status and fault detection displaying program;

[0028] e) determining whether there is a fault, and repairing the same, and in case a repair is not performed, a policing program shuts down the procedure or determines a shutdown when a fault does not exist;

[0029] f) in case of failure to perform a fault repair the self-repair program, then determines whether to shut down, if the election Optional shutdown program is executed, if the user choose not to shut the oxygen pressure storage tank is performed P. Found “Oxygen storage tank limit set pressure p. H is determined;

[0030] g) an oxygen storage tank if the measured pressure p. “Oxygen storage tank limit set pressure p. h is not established status and fault detection and display program is executed; if p. “Oxygen storage tank limit set pressure p. H stand establishment procedure is performed; and an oxygen storage tank for the measured pressure p. “The oxygen storage tank limit set pressure Pd Judgment, the oxygen storage tank if the measured pressure p. “The oxygen storage tank limit set pressure p. Set up booting process is executed; if the oxygen pressure storage tank Found p. “The oxygen storage tank limit set pressure PA Not established status and fault detection and display program is executed.

[0031] With the above features, the system 30 of the present invention provides a monitoring, control and fault self-diagnosis system which also contains artificial intelligence as well as relevant statistics that are shared with operators and registered users.

[0032] System 30 may be monitored via Internet since the PLC and other elements may be connected to a VLAN or a network via a specialized database containing artificial intelligence, including Internet, to remote control of the system from a different region of the world, wherein the system is only used by registered users through a security system.
