Real-time system based on Windows driver

Abstract

The invention discloses a real-time system based on a Windows driver, relating to a real-time expansion technology of a Windows system and aiming at solving the problems of poor real-time property and stability of Windows real-time expansion carried out by adopting a traditional driver, inconvenience in development and debugging of a control system, high Windows real-time expansion cost carried out by adopting an RTX (Real Time Executive) and other real-time software and the like. The driver and a dynamic link library (DLL) of the driver can be used for providing various services for the real-time system and packaging an interface function in the DLL; in addition, the driver also comprises a real-time kernel for managing and running real-time tasks; an application layer simulation program and a dynamic link library of the application layer simulation program can be used for providing an application layer debugging environment for a real-time control system, simulating the real-time task by adopting a Windows thread, simulating clock interrupt of the real-time kernel by adopting a Windows timer and simulating the communication and synchronization of the real-time task by adopting a communication and synchronization mechanism of the Window; and the real-time task and the dynamic link library of the real-time task can be used for separating a real-time task module from the real-time kernel and separately developing and debugging the real-time task module. An external interface card is used for providing a timer with high precision and high resolution for the real-time kernel and providing a data interacting and signal converting function and the like for the real-time control system and an external controlled object.

Description

technical field [0001] The present invention relates to a Windows system real-time extension technology, especially a real-time kernel directly embedded into the Windows driver to overcome the traditional Windows real-time software need to modify the Windows HAL source code and commonly used front and back structure driver real-time extension technology There are problems of poor real-time performance and stability, and inconvenient development and debugging of the control system. Specifically, it is a real-time system based on Windows drivers. Background technique [0002] Windows is a window-type multitasking operating system developed by Microsoft Corporation. As the most common operating system for PCs at present, there are many advantages and conveniences in the design and development of industrial control systems on its platform. But the Windows system is not a real-time operating system. In order to meet the needs of the industrial control field, it must be exte...
