The continuous penetration of internet technology into industrial control field has given rise to conceptual systems such as Industry 4.0 and Industrial Internet. Consequently

power plants are evolving towards digitization and informatization

with the intelligence and complexity of field-controlled objects increasing steadily. Control functions of conventional distributed control systems(DCS) are gradually becoming inadequate to meet these new demands. To enhance the maturity level of intelligent manufacturing in China

it is essential to strengthen the core computational control functions of DCS. In response

a novel collaborative control platform is proposed based on software-defined principles. This platform decouples the software and hardware of conventional DCS using software-defined concepts

reconstructs the control and configuration functions on the host computer

and designs and develops a dual-redundant computing engine and configuration and debugging tools. Additionally

protection mechanisms are established to ensure the operational security of the platform and the security of third-party data. This platform inherits the conventional configuration and control functions of conventional DCS while additionally supporting the implementation of various advanced intelligent algorithms. In terms of application

it can both enhance the control performance of conventional DCS and serve as an independent product providing high-quality computing services for other control systems. Consequently

it can be widely applied to various process control scenarios

offering users a reliable

efficient

flexible and cost-effective production control solution. Moreover

it provides an optional platform foundation for the future integration of cutting-edge computer technologies such as artificial intelligence and big data into DCS.
