摘要
根据大学生电子技术综合实验的要求,设计了一款简单的电网电压异常报警装置。基于Multisim8进行了各模块电路的设计与仿真,并制作成PCB板进行实际测试验证。当交流电网电压在190~250 V范围时,报警器不发声;当低于190 V或超过250 V时,报警器发出不同声响以示区别。在Multisim环境下进行电路的设计与仿真,直观、快速、方便,产品设计和调试周期短,成功率高。
According to the electronic technology synthesis experiment requirements of the students,a simple alarm unit for unwonted network voltage is designed.Each unit circuit is designed and simulated based on Multisim8,and it has been made to PCB in order to execute actual test.When alternating voltage in the range of 190 V to 250 V,no warning will be given by the alarm system.When it is lower than 190 V or higher than 250 V,different sounds will be given by the alarm system to differentiate.In Multisim environment,the design and simulation can be intuitive,rapid,and convenient with the short period and high success rate in product design and test.
