摘要
污水处理实时监控系统,其微处理器产生A/D信号,实现采样及转换的控制。实时时钟采用SD2300EP,在产生实时时钟的同时,提供8K字节的NVSRAM。网络接口采用串口转以太网模块,微处理器的232电平经过该模块后,实现与工业以太网的联接。同时利用SD2300EP和微处理器,对欠款用户采用密码系统实施管理。
In system on sewage realtime long-distance monitor,the MCU engender the control signal in order to control the sampling and conversion of A/D. As the chip of real tfme,SD2300 can bring realtime clock,at the same time,it have 8k byts of NVSRAM.The design gives interfaces for MCU to ethernet which can connect MCU with ethernet. Finally,aiming at the alarm function of the clock chip, it designs a function to prevent users who soutstand payment.
