摘要
提出了一种利用计算机声卡,配合继电器控制电路,实现声光报警功能的方法。讨论了电路设计的具体方案,并给出了PSpice模拟仿真结果。仿真结果表明,该报警电路简单、可靠、实用,完全可以实现声光报警功能。基于声卡的声光报警系统现已在桥梁监测系统中得到了应用。
A method which realized sound-light alarm based on the sound card of computer and relay controlling circuit were introduced. The circuit design scheme and the simulated result based on PSpice were put forward. The result demonstrated that the alarming circuit was simple, reliable and practical. The sound-light alarming system based on the sound card of computer had been used in the monitoring system of bridge.
