1. A device operation management method based on a device health degree, comprising:

determining, by a processor, a plurality of running status parameters of a device as well as critical ranges and preset values corresponding to the plurality of running status parameters respectively to construct a health degree evaluation model, wherein the plurality of running status parameters comprise at least one maintenance state parameter used for representing a health degree of a maintenance component and at least one key state parameter used for representing a health degree of a key and important component;

collecting running values corresponding to the plurality of running status parameters in real time in a running process of the device, wherein the plurality of running status parameters includes a gas pressure, and calculating, by the processor, a maintenance feature health degree corresponding to the maintenance component and a key feature health degree corresponding to the key and important component respectively according to the running values, the critical ranges, and the preset values through the health degree evaluation model;

determining, by the processor, the device health degree corresponding to the device according to the maintenance feature health degree and the key feature health degree;

determining, by the processor, a health degree grade matching with the device health degree from a plurality of preset health degree grades, and determining whether a running status corresponding to the device is healthy or not according to the health degree grade; and

determining, by the processor, when the running status is not healthy, an attenuation interval where the maintenance component and the key and important component are located correspondingly according to the maintenance feature health degree and the key feature health degree, so as to take corresponding management strategies for the maintenance component or the key and important component according to the attenuation interval, wherein the attenuation interval is an interval formed by ordinates in a performance attenuation characteristic curve; and

repairing at least one of the maintenance component or the key and important component based on the attenuation interval, wherein the repairing comprises replacing at least one of the maintenance component or the key and important component;

wherein the step of calculating the maintenance feature health degree corresponding to the maintenance component and the key feature health degree corresponding to the key and important component respectively according to the running values, the critical ranges, and the preset values through a preset health degree evaluation model comprises:

determining a critical lower limit value and a critical upper limit value in each critical range, and comparing the running values with the critical ranges and the preset values respectively to determine a range of the running values, wherein the range comprises a first range, a second range, and a third range, the first range denotes that the running values are greater than critical lower limit values and less than the preset values, the second range denotes that the running values are greater than the preset values and less than critical upper limit values, and the third range denotes that the running values exceed the critical ranges;

determining, when the range is the first range, the maintenance feature health degree corresponding to the maintenance component and the key feature health degree corresponding to the key and important component respectively according to the running values, the preset values, and the critical lower limit values through the health degree evaluation model;

determining, when the range is the second range, the maintenance feature health degree corresponding to the maintenance component and the key feature health degree corresponding to the key and important component respectively according to the running values, the preset values, and the critical upper limit values; and

determining, when the range is the third range, that the maintenance feature health degree corresponding to the maintenance component and the key feature health degree corresponding to the key and important component are both specified values; and

wherein the step of determining the attenuation interval where the maintenance component and the key and important component are located correspondingly according to the maintenance feature health degree and the key feature health degree, so as to take the corresponding management strategies for the maintenance component or the key and important component according to the attenuation interval comprises:

determining, according to the maintenance feature health degree, a maintenance attenuation interval and an attenuation period corresponding to the maintenance attenuation interval, wherein the maintenance component is located in the maintenance attenuation interval, and all maintenance feature health degrees within the maintenance attenuation interval are higher than or equal to a preset health degree lower limit value;

maintaining the maintenance component periodically according to the attenuation period;

determining a key attenuation interval according to the key feature health degree, wherein the key and important component is located in the key attenuation interval, the key attenuation interval comprises a running-in interval, a normal attenuation interval, and a fast attenuation interval, and a key and important component performance inflection point exists between the normal attenuation interval and the fast attenuation interval, wherein the key attenuation interval is at least twice as long as the attenuation period of the maintenance component such that the maintenance component is repaired at least twice before the key and important component is repaired during said repairing, wherein the repairing of the maintenance component comprises replacing a gas cylinder or inflating a gas tank; and

taking the corresponding management strategies for the key and important component when the key feature health degree does not reach the key and important component performance inflection point.
