中子应力谱仪原来的控制设备是从瑞典引进的,接线较为繁琐,且部分器件已经老化,使用和维护比较困难,结合这个问题,重新对控制系统进行了研制。新的控制系统由工控机、控制柜和操作手柄等组成。控制柜中装有西门子S7-300可编程控制器及其相关控制模块,美国丹纳赫步进电机驱动模块及国产步进电机驱动模块,PC机的主机及相关控制元器件。操作手柄盒可实现指定的步进电机的单动功能。西门子可编程控制器包括CPU、I/O、高速计数、步进电机控制等模块。针对样品台上的增量型编码器,选用S7-300系列高速计数模块,计数频率能达到200kHz,步进电机控制模块为西门子ET200S系列,脉冲频率可达到200kHz。
The original control equipment of neutron stress spectrometer was imported from Sweden. The wiring is more complicated, and some of the components have been aged, which makes it difficult to use and maintain. Combining with this problem, the control system was re-developed. The new control system from the IPC, control cabinets and operating handles and other components. The control cabinet is equipped with Siemens S7-300 programmable logic controller and its related control module, the United States Danaher stepper motor drive module and domestic stepper motor drive module, PC host and related control components. Operate the handle box to achieve the specified stepper motor single-action function. Siemens programmable logic controller, including CPU, I / O, high-speed counting, stepper motor control module. For incremental encoder on the sample stage, choose S7-300 series high-speed counting module, the counting frequency can reach 200kHz, the stepper motor control module is Siemens ET200S series, the pulse frequency can reach 200kHz.
