| 摘要: | 提出了一种基于FPGA的血液分析仪驱动电路设计, 以及一种基于频率测量的步进电机故障检测方法. 其驱动电路采用模块化和自底向上的设计方法, 实现对4个步进电机和24路电磁阀的并行驱动和实时故障检测, 并可通过串行通讯与主控机进行数据交换. |
| Abstract: | As an efficient instrument for analyzing sampled human blood, hematology analyzer has been widely used in the clinical testing fields. It requires multiple step motors and dozens of solenoid valves to work together for performing the given tasks. This article describes a driver circuit of hematology analyzer based on field programmable gate arrays. The driver circuit, which exchanges data with the upper controller through the serial communication in a bottom-up fashion, realizes the parallel drive and fault detection for the given four step motors and twenty-four solenoid valves. |
