摘要
介绍了一种基于快速数字信号处理DSP芯片TMS320VC5410A和压力、温度及相对湿度传感器的SF6气体密度和微水含量在线监测方法。详细讨论了SF6气体密度、微水含量与温度、压力的关系,并给出了相应的硬件框图和部分软件实现。数据处理模块采用DSP芯片,充分发挥了其强大的数字信号处理能力,速度快,精度高。另外,丰富的片内资源有效地简化了设计的复杂性,增强了系统的电磁兼容性,降低了设计成本,从而使得该方法具有较好的应用前景。
An on-line monitoring method of SF6 gas density and humidity is proposed, which is based on DSP TMS320VC5410A-120, temperature, pressure and humidity sensor. The relationship among density, temperature and pressure is analyzed in detail. The relevant hardware diagram and partial software implementation is also discussed in detail. The digital signal processing capa-bility is fully displayed by DSP. It has high speed and accuracy. In addition, abundant resources are integrated on the chip to optimize the sys...
