Problems solved by technology
[0002] Electric boilers currently on the market are equipped with monitoring systems for liquid level, water temperature, and water pressure. During the process of boiler water inlet and outlet, the changes of the above parameters can be monitored in real time, which is more convenient, but the detection equipment and systems used depend on PLC. The program control of the control cabinet or single-chip microcomputer has a complex structure and high cost; on the other hand, the use of circuit program control and monitoring stability is poor. If there is a problem with one of the modules or components, it will cause errors in the monitoring of the entire system and accidents are prone to occur
