基于PLC电热水器水箱水位检测系统的设计

Design of the water level measurement system of the electrical water-heater tank based on PLC

针对电热水器使用存在的弊端,如:在使用时,用户想知道水箱中剩有多少热水,能用多久;水箱出现干烧现象等,提出了一些改进措施,并设计了利用PLC对电热水器水箱水位检测的控制系统。

The electrical water-heater is popularized. But it also have some disadvantages：for example; people want to know how much hot water in the tank and how long he or she can take;the tank is heating when there is not enough water in the tank, etc. Some improvements are improved on these disadvantages and the water level measurement control system of the electrical water-heater tank is designed based on PLC.
