摘要
鉴于AT89S52采用传统的方法驱动继电器时出现的问题,以HK4100F继电器为例,对其驱动电路进行了详细地分析与改进。实验证明,改进后的电路能稳定工作,对解决继电器驱动电路的异常问题具有参考价值。
This paper makes an analysis on AT89S52's interface circuit that drives relays in response to the phenomena that the classical interface circuit frequentIy faiIs to work when driving reIays,and then propose an improved circuit,taking HK4100F reIays as an example.Experiments show that the improved circuit can work steadily and can be a vaIuabIe refer-ence for soIving the probIems of the reIay drive circuit.
