【摘要】 针对需要火花控制的静电除尘电场设计一种基于TI公司TMS320LF2407A的控制系统。系统硬件采用ARM9与DSP双系统设计,DSP作为实时控制核心及时控制电场,ARM9完成与上位机通信及网络的构建。软件部分分析了火花检测及灭火花处理及在实际使用时要注意的系统保护问题并提出了解决方法。该系统经过试运行使用表明:系统能迅速检测火花并达到火花率控制水平,对各种极限工况的检测及时,反应灵敏,能较快地跟踪所设定的高压电场电压、电流等状态,同时能保护系统的安全运行。更多还原

【Abstract】 Aiming at the electrostatic precipitation that requires spark detection,a control system based on TMS320LF2407A is designed. The system hardware is a dual system design based on ARM9 and DSP. The DSP systems,as the core of control,timely control the electrical field. The ARM9 is used to complete the communication with host computer and the construction of network. This paper analyzes the spark detection,spark quenching and the protect problem to which should be pay attention in actual use,and proposes solutions in the software part. After trial running,the result shows that the system can quickly detect sparks and achieve the level of spark rate,which can timely detect and quickly respond task under a lot of extreme conditions. It can fast track the set voltage and current status of high-voltage electrical field,and make sure the system runs safely at the same time.更多还原
