Intelligent ecological fish tank solution development

The development of fish tanks can be generally divided into three generations. The first generation uses ordinary glass as the carrier, which is a container for ornamental purposes and specially for raising aquatic animals and plants. This kind of fish tank has insufficient water oxygen supply and frequent replacement of water resources, resulting in a lot of waste of water, often cleaning up metabolic waste, and Metabolic waste contains many germs, pollutes water resources, causes the death of fish, and has many deficiencies.

The second generation is an ecological fish tank, which incorporates functions such as hydroponic flower pots and table lamps. This generation of ecological fish tank uses the principle of ecology to integrate the basic ecosystem into the fish tank to form a tiny ecosystem. However, although this tiny ecosystem has the principles of ecology, the ecosystem has poor self-regulation ability, is easily damaged, and cannot be restored. Lacking artificial intelligence control and detection, it belongs to a free-range ecosystem.

At present, the third type of intelligent ecological functions are complete and highly intelligent, but the prices on the market are generally relatively high, which seriously restricts the promotion and development of intelligent ecological fish tanks. Based on the above backgrounds, this project designs an intelligent ecological fish tank based on the STC89C51 single-chip microcomputer as the basic control core and the control circuit for detection by various sensors. Powered by several solar panels, it integrates related systems such as water temperature control, oxygenation control, filtration control, sewage system, water purification system and intelligent replenishment system to form a control system with multiple functions.

1. Design objectives and hardware structure block diagram of the intelligent fish tank system

This project is designed with STC89C51 microcontroller as the control core, an intelligent ecological fish tank that integrates multiple functions into one. The fish tank has an artificial intelligence working method; the hardware design part consists of a single-chip microcomputer control module, LED lighting module, photosensitive angle adjustment module, automatic oxygen supply module, solar power supply module, data conversion module, infrared water quality detection module, waste automatic cleaning module, etc. consists of parts.

Among them, the lowest system of the single-chip microcomputer is the control core, and the solar power supply system is realized by combining several solar cells with a power conversion circuit. Since the output voltage of the solar cell panel is unstable, the output voltage is converted to 5 V and 1 2 V stable by the voltage stabilizing circuit. Direct current, in order to ensure that the solar panel receives enough light as much as possible, the light intensity of each direction is detected by the light detection module, and the angle of the solar panel is adjusted.

The oxygen control system detects the oxygen content of the water quality through the oxygen sensor. When the oxygen concentration in the water body is less than 8-9 mg/L, the oxygen supply pump is started to supply oxygen. Generally speaking, the content of microorganisms is more, and the amount of oxygen in the water body is relatively reduced. Therefore, the sensor for detecting the oxygen content will also transmit the detected data to the impurity remover. The impurity remover used in this design is a cylindrical volume structure with both ends connected, the inner cylinder moves relative to the shell, and the inside of the inner cylinder is inlaid with strip-shaped protrusions around the disk. The rotation of the inner cylinder makes the water flow in the bottom layer drive the impurities, and there are adsorption and collection devices inside. The temperature detection module is realized by a digital temperature sensor, and the temperature data is transmitted through the data communication with the single-chip microcomputer. According to the temperature value set by the user, it is determined whether to perform heating and other operations. If heating is required, start the heating rod for heating and finally keep the temperature at near the set value.

The feeding period of the bait is directly controlled by the single-chip microcomputer. According to the set time point, the feeding device is directly controlled by the single-chip microcomputer, and a fixed amount of bait is released at a fixed time. The display is mainly used to display and set, such as the setting of bait feeding time, time setting, display feeding times, feeding amount, temperature value, etc., and whether to heat or not.

2.1 Real-time collection of environmental data. This system can periodically and regularly read sensor-related data through various sensors, such as digital temperature sensors, liquid level sensors, water turbidity sensors, light intensity sensors and other sensing modules. In this way, the real-time collection of sensing data is realized, which greatly facilitates the user's real-time understanding of various environments in the smart fish tank ecosystem.

2.2 Multi-angle display of data, the data collected by various sensors in real time can be viewed through the liquid crystal display in the circuit, and the above-mentioned collected data can also be displayed in various ways, such as using bar graphs and tables , line graphs, etc., and the historical data is stored in the circuit, which can be viewed at any time.

2.3 Digital setting, the user can set the digital threshold or range of the parameters that need to be set or adjusted through the key module on the display, such as setting the temperature range, when the temperature data collected by the temperature sensor exceeds the set value range, the MCU will issue corresponding commands for heating or alarming.

2.4 Management of information data, through display, data acquisition module, key control part and other system modules, the user finally realizes the intelligent management of the entire system, which is convenient for users to watch and switch various parameter values of the environment at any time, and present them in various ways At the same time, users can view historical data conveniently and quickly at any time.

This design is a miniature artificial intelligent ecological environment system, in which various objects, such as animals and plants, lighting environment, water, etc. constitute a three-dimensional ecological landscape. Regularly read sensor-related data, so as to realize real-time collection of sensor data, which greatly facilitates users' real-time understanding of various environments in the smart fish tank ecosystem.

In addition, the data collected by various sensors can be collected in real time, and various data can be viewed through the liquid crystal display in the circuit, and the above collected data can also be displayed in various ways, such as using bar graphs, tables, broken lines The graphs and other methods are presented, and the historical data is stored in the circuit, which can be viewed at any time.

In addition, the user can set the digital threshold or range of the parameters that need to be set or adjusted through the key module on the display. When the temperature data collected by the temperature sensor exceeds the set range, the microcontroller will issue a corresponding command to heat or adjust. Alarm Furthermore, the water in the artificial intelligent ecological environment system is not only used as a living environment for fish, but also serves as a material for irrigating plants and providing plant nutrients. The plants in it can purify water quality and provide food for animals in it. And it is constantly carrying out photosynthesis and continuously providing fresh air, so the intelligent ecological fish tank system is not only a small fish tank system, but also a real landscape.
