The invention discloses a laser head driver architecture and method. The laser head driver architecture comprises a unified interface module, a driver management module and a driver module, wherein the unified interface module is used for receiving a command sent by a user layer, analyzing the command and sending the analyzed data to the driver management module; and the driver management module analyzes and executes the analyzed command, and the driver module is called during command execution and drives an action of a laser head. The laser head driver architecture and method are realized by adopting a Windows service technology: a Windows service running process is automatically loaded after system startup and runs in a background. When a laser head driver has a problem and crashes, the service is automatically restarted, so that the driver device.exe is not influenced.
