【摘要】 随着同步辐射光束线技术的发展，单色器的分辨率越来越高，采用的复杂机构要求极高的 机械转动和直线运动精度，对光束线控制软件的性能提出了新的要求。另一方面，同步辐射实验 室新建光束线的数量逐渐增多，对控制软件设计的压力增大，希望有一种可移植的、标准化的控 制软件。变包含角球面光栅单色器使用分层控制技术，层之间用以太网联接。底层是硬件抽象 层，直接处理与所有硬件有关的操作；上层为高级用户界面层，提供用户控制的指令，可以满足不 同用户端软件的需求。同时还介绍了一种变包含角光栅单色器的数值解法。更多还原

【Abstract】 The resolution of monochromator becomes much higher with the development of synchrotron radiation beamline technology, it demands high performance of control software to drive the complex configuration of mechanical rotation and translation. On the other hand, with the number of the constructed beamlines increases rapidly, it imposes a large force on developing, a migrated and standard control software. A multi - layer technology introduced to variable angle spherical grating monochromator (VASGM) control in which the layers being inter - connected by Ethernet was discussed. The lower layer, a hardware abstract layer, operates the hardware directly and the top layer, a graphic user interface, processes the user’s command and passes corresponding operation to the lower layer. The top layer can be flexibly connected with different control software. A numeric solution of VASCM was also given.更多还原
