Description

Smart fish tank management system {smart automatic fish tank}

The present invention relates to a water tank, and more specifically, a system necessary for raising companion fish through an embedded system using temperature and water level sensors to manage water exchange, oxygen saturation and temperature, which are essential elements for companion fish to live, and automatically change water It is about a smart water tank implemented to do this.

According to the 2020 Companion Animal Report, the proportion of fish among companion animals increased by 2.3% this year compared to last year, and the size of the companion fish market is on the rise. On the other hand, as the size of single-person families increases, there are many difficulties in managing companion fish as they often leave home for travel and business trips. Companion fish is an essential element that needs to be managed regularly, and there are three main factors: pH, oxygen saturation, and temperature. First, in the case of pH, most water tank management is performed using a pH sensor, and the underwater pH is managed using this. pH sensors on the market are expensive, and additional devices are required to use the pH sensor, so it is a burdensome price compared to the existing ones. In the case of temperature management, the premium water tank not only manages the temperature through a temperature sensor, but also controls the water temperature by using a heater and a cooler. This increases the cost of the heater, cooler and temperature sensor, which increases the price of the tank. Lastly, oxygen saturation is the minimum amount of dissolved oxygen that fish can survive normally, about 5ppm. However, the longer the companion fish spends in the tank, the more contaminants such as excrement and salt are present, the oxygen consumption of the companion fish in the tank increases and the oxygen concentration decreases. To solve this problem, an oxygen supply and a filter are used, but they are not efficient and have the disadvantages of being expensive. Not only that, but it is necessary to periodically supply food, but there is a tendency for the owner of the companion fish to not do it regularly and to forget it. As a result, the need for a system that can automatically manage companion fish has increased. An object of the present invention is to provide convenience to companions through a smart fishbowl management system.

In order to solve the above-mentioned problems, we intend to manufacture an automated control device by using an embedded system to efficiently manage essential elements for survival of companion fish, such as periodic water exchange, oxygen supply through a filter, and temperature control through a heater. In addition, we aim to create a system that provides convenience to companions by supplying food, and visually shows the environment of the tank by indicating the current status of the tank through the display.

In order to solve the above-mentioned problems, we intend to use an embedded system to efficiently manage pH, oxygen saturation, and temperature, which are essential elements for the survival of companion fish, and to manufacture an automated control device. In addition, we aim to create a system that visually shows the environment of the tank by providing convenience to companions through periodic water replacement and feeding, and by indicating the current status of the tank through the display. It manages pH by supplying water from the sub tank to the main tank using an underwater pump, and manages coral saturation by supplying oxygen through the air pump of the filter. In addition, a temperature sensor is used to measure the temperature of the water tank, and a relay switch and a water tank heater are used to properly control the temperature of the water tank. In addition, the servo motor is controlled so that the food can be supplied at the set time, and the food is supplied, and the sensor value that measures the environment of the tank is received and displayed on the display. The food feeder used for control using the servomotor is manufactured using 3D printing technology, and the drop supply method is used to supply food according to the set time through the servomotor.

The smart fish tank management system of the present invention can provide an optimal environment for companion fish to survive by automatically performing the process of water exchange and water level control through a pump, temperature control using a heater, and food supply. Although it is a system that efficiently manages pH, oxygen saturation and temperature, which are essential factors for managing companion fish, it has the advantage of being cheaper than existing products. In addition, the domestic market for ornamental fish products in 2020 was estimated at 400 billion won, and when it expands to the global market, it can be seen that it is a fairly large market size of 42 trillion won. Therefore, this invention is a product that shows the potential to generate a lot of economic profit.

The present invention utilizes 3D Solidworks to produce the entire assembly, is equipped with a heater, maintains the optimum environment for fish in the water tank at 25°C, and periodically supplies oxygen through a filter, maintains oxygen saturation in the water tank, and removes foreign substances. In addition, it is possible to periodically supply food through the feeder and efficiently change the water over time through the WATER PUMP in the main and auxiliary tanks.

The feeder was manufactured by 3D printing using an SLS printer for high strength and assembly.

In the case of water change using a pump, the used water pump consists of an impeller and a volute. Since the water level should not overflow, the impeller rotates and the fluid is pushed out by centrifugal force to increase the speed, and the volute becomes smaller as the area goes to the discharge side and the pressure It increases and uses it to control the water level and determine the flow rate of the pump

The embedded system forms a closed circuit with a temperature sensor, receives the water temperature as input, compares it with the set value, and operates a pump for water exchange if it is high, and operates a water tank heater if it is low. The water exchange is performed by periodically operating the pump according to the set time, and the value of the water level sensor is input and the water is adjusted so that the water does not overflow. In addition, the servo motor is operated according to the set time to automate the feeding, and information on the temperature, water level, and feeding time of the tank is displayed on the LCD.
