摘要
对故障进行准确、清晰、实时报警是评估监控保护装置性能的一项重要指标,同时也是其在实际运行环境中所必须具备的基本功能。在构建智能化高压开关柜微机监控保护装置总体结构的基础上,针对现有故障报警等方面的不足之处,利用MCS51系列单片机和语音ISD25120芯片,开发出1块集语音报警、液晶显示及打印于一体的多功能语音报警卡,并对其功能、原理框图、硬件电路以及相应的软件流程和具体编程进行说明。现场运行表明,该语音报警卡完全可以满足故障报警的实时性和可靠性要求。
Real-time,clear and correct sound alarming is an important index to evaluate the performance of supervision and protection equipment,and also is a basic function in practical running environment. On the basis of computer supervision and protection equipment for intelligent HV switch board and considering the deficiency of current sound alarming,a sound alarming card using MCS 51 series single-chip and ISD25120 sound chip is developed,which integrates several functions of sound alarming,liquid crystal display and printing. Its functions,principle,hardware circuit,software design and detailed programming are illuminated. Practice proves that it satisfies the requirements of real time performance and reliability.
