摘　　要：给出了基于二线制的太阳能热水器的硬件电路结构和控制方法。该系统以MA86L508单片机为核心,采用二线制方式将温度/水位传感器与CPU之间互连,通过对电容的一次充放电循环就可以实现对温度和水位的一轮采集,简化了系统结构、提高了温度/水位检测效率、降低了成本。The hardware circuits and control method of the solar energy water heater based on the dual-wires are designed. The system takes the MA86LS08 as the core,it makes device to connect the sensors of temperature and water level to MA86L508 using the dualwires. The CPU can realize the collection of the temperature and water level value by a charging and discharging cycle of the capacitor at the same time. It has the characteristics such as simple structure, high efficient and low cost.
