With the rise of intelligent manufacturing

the MES system will become an enabler for the manufacturing industry to integrate physical space and virtual space. The existing MES system is insufficient in its architecture design to meet explosive and disruptive business needs. This paper proposes a MES system architecture based on microservice

which is composed of interaction layer

decision layer

data layer and perception layer. Each layer is connected by event center

and infrastructure is provided by IT model and supporting platform. This paper expounds the key technologies of MES–MSA architecture

and gives some application scenarios of this architecture. It effectively solves the technical problems of the existing system architecture

such as high coupling degree

weak expansibility and difficulty in integration

and meets the new requirements of intelligent manufacturing for MES system business.
