基于单片机的水温水位控制系统设计

水温水位控制系统以STC89C52单片机为控制核心,采用温度-电流变送器XTR106、电流环接收器RCV420进行信号调理和信号变送,控制加热丝进行加热;水位控制子系统由555定时器、继电器和水泵构成,完成了对容器内水位控制;同时,数码管显示水的实际温度与设定温度。经测试,整个系统实现了预期功能。

The water temperature and water level control system is based on the STC89C52 microcontroller. The temperature cur-rent transmitter XTR106 and the current loop receiver RCV420 are used for signal conditioning and signal transmission, and theheating wire is controlled for heating. The water level control subsystem is composed of 555 timer, relay and pump, which control thewater level in the container. At the same time, the digital tube displays the actual temperature and the set temperature of the water.After testing, the whole system has achieved the expected function.
