Ling You-zhu · Automation and Instrumentation · 2007
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 time,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.
