Design of Intelligent Fish Tank based on single Chip Microcomputer
Summary
In recent years, with the rapid development of embedded, smart home has also entered peoples life. Intelligent fish tanks have not developed rapidly. According to the analysis and research of the related equipment in the market, I design and develop a multi-function intelligent watch fish tank control system from the point of view of system integration. The control system takes STC12C5A60S2 single chip computer as the control core, combines the sensor technology, integrates various control functions, including temperature detection, automatic oxygenation, automatic water exchange, light change and automatic feeding, etc. At the same time, a Bluetooth communication module is designed in the system, which can realize the remote control of the fish tank. Administration and Management The whole system is divided into two parts: the first part is the control part with STC12C5A60S2 as the core, which realizes the setting, storage, and processing of various control parameters. The second part is the mobile phone Android part, through the mobile phone APP can real-time control the fish tank, parameter setting, achieve human-computer interaction. Bluetooth communication technology is adopted between the two parts, and the data information is transmitted interactively between the upper computer and the lower computer. The system is designed and developed according to the demand of the current market. It forms an integrated control system with the functions of automatic oxygenation, automatic water exchange, light changing and automatic feeding. At the same time, the system has the advantages of flexible design, low cost and convenient mass production. It can be widely used in the installation of ornamental fish tanks in homes and hotels.

Subject background
With the rapid development of our national economy, the peoples pursuit of quality of life has been improving, and people no longer like the previous generation of consumption concept. People pursue higher and higher living grade, which leads to the improvement of consumption level, the individuation of home environment and the environmental protection. At the same time, people pay more and more attention to it. At the same time, there is a great opportunity for the development of the related industries such as smart home. Modern urban life causes people to bear all kinds of pressure many people need to get the spiritual comfort the bottom of my heart longs to embrace the natures tranquility and the harmony the pet has already become an unceasing trend. And the life of a lively fish grass is pleasant The fish bowl can not only bring people the beautiful feeling of spring, but also beautify the living environment, make people return to the long-lost green, and let themselves return to the embrace of the beautiful scenery of nature. In such a new trend, raising a few ornamental fish will become a new trend. Intelligent fish tank control system is produced under this demand. The aquarium is not just a container of fish and grass, it is a miniature of nature, a relatively complete small ecosystem. In recent years, this kind of ecological aquarium with aquatic grass, ornamental fish as the main body is called 'miniature fish grass garden', people are very fond of it and pursue it. But in order to make a suitable environment for water and grass, it is a time-consuming and laborious thing to keep a small fish living for a long time. Many people in urban areas are busy with their work or have no time to take care of the fish under the pressure of life. So the general outcome is mostly dead grass dead fish dry dead. So there are a lot of equipment for purifying and improving the water quality of fish tanks. At present, the control equipment for fish tanks that are often seen on the market are: water exchange equipment, oxygen pumps, feeding equipment, etc., but they are generally not intelligent. Devices that need to be manually controlled to work alone. However, if a number of independent fish tank control devices are mechanically formed into a multifunctional control device, it is necessary to The cost of these devices is very high, and when these devices are assembled together, there is a waste of electricity, which is not convenient for centralized and unified management and control.
System mechanism
The intelligent fish tank system is divided into the hardware module of lower computer and the Android software module of mobile phone. The main function of the hardware module is to control the operation of the fish tank and to report the temperature, while the software module sends commands and parameters to display the temperature value. Hardware module and software module communication using Bluetooth serial port, simple and fast. The architecture diagram of the system is shown in the diagram.
The design of the intelligent fish tank control system is carried out on the premise of full investigation and investigation of the different types of fish tank control equipment available in the market at present. The whole intelligent fish tank control system is divided into the following functional subsystems: artificial / timed oxygenation system, artificial / timed water circulation system, LED light changing system, artificial / timed feeding control, real-time temperature monitoring system and so on. These subsystems work independently, but each subsystem is controlled by a single chip microcomputer. The intelligent fish tank control system also combines the clock circuit module / watchdog / reset circuit to facilitate the automatic control of the system and the functional parameters of each subsystem. The device is connected with the Bluetooth data transmission circuit, and commun
