Problems solved by technology

[0002] At present, the commonly used maintenance methods for equipment are: according to the inherent mean time between failure (MTBF: Mean Time Between Failure) of the product, a fixed maintenance cycle such as daily, weekly, monthly, and annual is designed, and the equipment is regularly repaired or replaced. When using equipment, the failure time will not be exactly the same as the MTBF when it was designed. This fixed daily, weekly, monthly, and annual maintenance cycle may be too large for some equipment, while it may be too designed for other equipment. Small, the former will cause the designed daily, weekly, monthly and annual maintenance methods to fail to effectively ensure the normal operation of the equipment, but the latter is very likely to cause waste of human and financial costs

Embodiment Construction

[0110] A method for determining the maintenance interval of equipment in this embodiment, such as figure 1 described, including the following steps:

[0111] S1, counting the life data of any product in the equipment obtained by the fixed-number censored life test, and using the maximum likelihood estimation method to analyze the life data of the product to obtain the average life of the product;

[0112] S2. Dynamically adjust the maintenance interval of the product by using the average life of the product and the reliability function introducing the state repair factor;

[0113] S3. Determine the maintenance interval time of the equipment according to the maintenance interval time of each product.

[0114] Using the maximum likelihood estimation method to analyze the life data of any product in the equipment obtained from the fixed-number censored life test, the average life of the product is obtained, and then according to the average life of the product and the reliabilit...

Abstract

The invention relates to a method and system for determining equipment maintenance interval time and electronic equipment. The method comprises the steps: firstly, carrying out the statistics of the service life data of any product in equipment obtained through a definite truncation service life test, carrying out the analysis of the service life data of the product through a maximum likelihood estimation method, and obtaining the average service life of the product; secondly, dynamically adjusting the maintenance interval time of the product by utilizing the average service life of the product and a reliability function of introducing a state repair factor; and finally, determining the maintenance interval time of the equipment according to the maintenance interval time of each product. By dynamically adjusting the maintenance interval time of each product forming the equipment, the dynamic maintenance interval time of the equipment is obtained and is more accurate, so that the normalwork of the equipment is ensured, and the waste of manpower and financial resources is avoided.
