The Design of Control System for Water Dispenser Water Content Based on MCU
Abstract. This page proposed a Water dispenser water temperature and water yield control system which used MCU AT89S52 as the core, it can be achieved heating water and monitoring water levels. To preset temperature through the input module, to detect water temperature by waterproof model DS18b20 temperature sensor and displays the real-time temperature of drinking water by using 1602 LCD screen. Compared with the preset temperature real-time temperature, heating water if the real-time temperature is lower than the preset temperature, otherwise stop heating. The water level can be positioned though the ultrasonic module, can be sounded the alarm when the liquid level height below the warning line. The system has very high use value with the advantages of simple design.
- Introduction
The application of single chip microcomputer (SCM) in electronic products is becoming increasingly wider and deeper. Temperature measurement and control are also applied in many electronics. This design mainly aims to design a new intelligent control system which has the functions of temperature measurement, temperament control, and liquid level alarm.
- Design Idea and Scheme
The mainframe unit, consisting of AT89S52 SCM and relevant memorizer, is the core of design. The name of key component and the main functions of the key parts in the circuits are as follows:
(1)AT89S52: it refers to the control of the collection procedure, collection mode and alarm process of monitoring system data; it is also the core processor of the whole system. At first, SCM compares the on-the-spot temperature measured by the sensor and the preset temperature. Providing that the on-the-spot temperature is greater or less than the preset temperature, the signal should be output to control the work of the heater, so as to control the temperature.(2Liquid crystal display LCD1602:it is used the display the current temperature, the set temperature, and the height of water level.(3)DS18B20:singlet line digital temperature sensor can be directly transformed into serial digital signal, so as to be processed by SCM.(4)Buzzer: it is used to point out the various states of the drinking fountains of users.(5)Key: modules are input to control SCM, in order to complete various kinds of functions.
3. Design of System Hardware
All SCM systems have crystal oscillators. Crystal oscillator is very effective in SCM system. It combines the internal circuit of SCM, generating the necessary clock frequency of SCM. The 2nd International Conference on Mechatronics Engineering and Information Technology (ICMEIT 2017) Advances in Computer Science Research, volume 70 668 execution of all instructions of SCM is based on the basis. The higher the clock frequency offered by the crystal oscillator is, the faster the operating speed of SCM is. Crystal oscillator operates in the resonance state with a kind of crystal which can transform electric energy and mechanical energy mutually.
4. Summary
This paper primarily introduces the overall design, hardware system design, and software system design and debugs method of the idea that the drinking fountain is controlled by the button. The optimal case should be selected with continuous design debug and improvement. The selected scheme has strong functions, high precision, good reliability, high stability, and strong anti-interference performance.

Research on Design of Intelligent Water Dispenser Based on Micro Controller System
Abstract. Micro controller computer is a kind of common electronic products, and it is often used for temperature detection in electronic devices. This paper will make full use of the advantage of micro controller computer to design an intelligent water dispenserwith the temperature detection and control function. In the design, we firstly determine the requirements and solutions, and then analyze the hardware configuration as well as the software program, finally debug the hardware and software in order to provide reference for relevant researchers. Introduction
MCS (Micro Controller System) application is very broad in industry. For instance, there are intelligent electric power system based on micro controller system, intelligent vehicle speed control system based on micro controller system, intelligent data acquisition system based on micro controller system, displacement measurement system based on micro controller system and intelligent control system based on micro controller system. MCS is actually a set of RAM, CPU, ROM, input and output systems, as well as timers, counters, including micro computer system. Its micro intelligent computer system makes it possible to realize the automation and intelligence of the electric appliance. With the rise of peoples attention to the health of drinking water, most families, enterprises and government units are equipped with dr
