| 中文摘要: |
| 火焰光度计主要用于检测溶液中碱金属离子浓度,在医疗、农业、工业中有着广泛的应用。目前,火焰光度计主要采用单片机电路或通用集成电路构成控制系统,由于系统可扩展性差,标定操作复杂,提出了采用S3C2440作为火焰光度计控制系统核心器件的改进方案,采用Linux嵌入式操作系统、触屏操作界面,用软件实现标定。详细分析了火焰光度计的工作原理、控制系统的硬件设计以及软件实现。整个系统稳定可靠、人机界面友好、操作简便、功耗低和智能化程度高。 |
| 英文摘要: |
| Flame photometer is mainly used for detecting concentration of alkaline metal ion in solution, and has been widely used in medical care, agriculture and industry. Currently, the flame photometric control system is poor in scalability and too complicated in operation, for it mainly consists of the MCU circuit or general integrated circuit. Therefore, an improved flame photometric control system was put forward, adopting S3C2440 as master chip, using the Linux operating system and touch screen operation interface, with software to realize calibration. Detailed analysis was given for the working principle of the flame photometer, hardware design and software realization of its control system. The whole system is having a friendly man machine interface, an easy operatability, a high degree of intelligence and a low power consumption. It is also stable and reliable. |
