Design of Intelligent Control System of Electric Water Heater Based on 51 MCU
Abstract: With the continuous development of society and progress of human science and technology, all trades and professions are making their product more digital and intelligent. The intelligent control system of electric water heater designed by this system aims at simplifying operation and can be applied to users of all ages. The design uses the STC98C51 MCU as the core to design the intelligent electric water heater. Temperature sensor, water level sensor and infrared remote control module are used to complete the design of the overall system. The hardware of heater control system includes a processor MCU control section, temperature acquisition module, water level control module, LCD1602 display module, relay drive module, buzzer module, infrared remote control module, LED module and keyboard module indicator. In this paper, the characteristics of the chip used in the control system of the electric water heater are introduced in detail, such as STC89C51, DS18B20 and so on. The following functions are mainly realized in this system: automatic control of water temperature and water level, timing heating, infrared remote control setting, dry burning alarm, LCD screen real-time display and reset function. The software part elaborates the modules separately by using the flow chart, and carries on the detailed annotation to the whole system procedure.
