Embodiment 1

[0052] This embodiment provides a collaborative system for predictive maintenance of after-sales equipment based on digital twins, such as figure 1 shown, including:

[0053] Building block 11, used to build a collaborative maintenance seven-dimensional model based on the digital twin of the equipment manufacturer;

[0054] The acquisition module 12 is used for the real-time acquisition and transmission of operating state parameters of the equipment based on the collaborative maintenance of the constructed digital twin to maintain the seven-dimensional model;

[0055] The analysis module 13 is used to predict and analyze the collected equipment operating parameters based on the constructed digital twin collaborative maintenance seven-dimensional model, and obtain equipment prediction results;

[0056] Judging module 14, for judging whether the state of current equipment is normal according to the obtained equipment prediction result;

[0057] The processing module 15 is used...

Embodiment 2

[0126] A digital twin-based after-sales equipment predictive maintenance collaboration system provided in this embodiment is different from Embodiment 1 in that:

[0127] In this embodiment, a certain bottled water production process is taken as an example for illustration.

[0128] The Markov chain model is a dynamic stochastic model named by the Russian mathematician A.A.Markov. It predicts the future movement of these variables by analyzing the actual movement of random variables. This process requires no aftereffect, that is, the probability distribution of the next state can only be determined by the current state, and has nothing to do with the previous state. That is to say: the past only affects the present, not the future, and only the present affects the future.

[0129] The state of a device can be modeled simply as Figure 7 Shown: normal state (N), degraded state (Abn) and fault state (F). Failure rate λ and repair rate μ are the reciprocals of mean time to fai...

Abstract

The invention provides an after-sales equipment predictive maintenance cooperation system based on digital twinning, and the system comprises: a construction module which is used for constructing a cooperative maintenance seven-dimensional model based on digital twinning of an equipment manufacturer; an acquisition module which is used for acquiring and transmitting operation state parameters of the equipment based on a digital twinning collaborative maintenance seven-dimensional model; an analysis module which is used for carrying out prediction analysis on the collected equipment operation parameters based on the cooperative maintenance seven-dimensional model based on digital twinning to obtain a prediction result of the equipment; a judgment module which is used for judging whether thestate of the current equipment is normal or not according to the obtained equipment prediction result; a processing module which is used for carrying out preliminary diagnosis on an abnormal problemof the current equipment when the current equipment is judged to be in an abnormal state, so as to obtain a preliminary diagnosis result; and a display module which is used for visually displaying theoperation state, the prediction trend and the preliminary diagnosis result of the equipment to production operators and equipment maintenance participants in real time based on the cooperative maintenance seven-dimensional model based on digital twinning.

Description

technical field [0001] The invention relates to the technical field of after-sales equipment maintenance, in particular to a digital twin-based predictive maintenance collaboration system for after-sales equipment. Background technique [0002] With the emergence of the Internet of Things and intelligent interconnection, the manufacturing industry has begun to rely on this useful tool for service-oriented innovation, to solve problems in production and service, to improve product quality, and to promote service innovation. From a manufacturing facility and equipment perspective, this means considering extended equipment life expectancy, which is a key factor for more sustainable operations and a business opportunity for equipment manufacturers. For equipment manufacturing enterprises, if they can provide more reliable products and after-sales service, they will gain higher reputation and benefits. For equipment users, if they can get fast and accurate maintenance services, ...
