Abstract
The utility model provides a freshwater aquaculture dissolved oxygen concentration monitoring device, which comprises a dissolved oxygen sensing module, a temperature sensing module, a main control module, a display module, a key module and an air pump relay control module. The monitoring device is characterized in that the main control module is respectively connected with the dissolved oxygen sensing module, the temperature sensing module, the display module, the key module and the air pump relay control module. The dissolved oxygen sensing module converts the concentration value of oxygen dissolved in water into a current signal. The current signal is then converted and amplified into a voltage signal which is sent to the main control module for further processing. Meanwhile, the main control module collects the environment temperature value through the temperature sensing module and compensates the temperature of the dissolved oxygen value to obtain an accurate dissolved oxygen value. When the dissolved oxygen value of the oxygen in water fails to meet a preset value, the air pump relay control module then makes an air pump started for inputting oxygen into water until the dissolved oxygen value satisfies the requirements. The key module is applied for setting corresponding dissolved oxygen threshold values. The display module is applied for displaying the current dissolved oxygen value concentration and relevant parameters.
Description
Technical field
The utility model relates to a kind of supervising device, especially freshwater aquiculture oxyty supervising device.
Background technology
In freshwater aquiculture, the Detection & Controling of the input of feed, disease prevention and cure, water temperature, oxygen in water concentration are all extremely important to improving cultured output and quality.Because the dissolved oxygen concentration in the water receives the influence of water temperature, oxygenation is untimely and cause the phenomenon of culturing loss to happen occasionally.
Summary of the invention
In view of above these situation, the utility model provides a kind of freshwater aquiculture oxyty supervising device.
The utility model provides a kind of freshwater aquiculture oxyty supervising device; Comprise dissolved oxygen sensing module, TEMP module, main control module, display module, key-press module, air pump relay control module, it is characterized in that: the main control module is connected with dissolved oxygen sensing module, TEMP module, display module, key-press module, air pump relay control module respectively.The dissolved oxygen sensing module converts the oxygen density value that dissolves in the water to current signal, after the process conversion zooms into voltage signal, delivers to the main control resume module.The main control module also will be simultaneously gathered ambient temperature value through the TEMP module, and the temperature of oxygen dissolving value is at that time compensated, and obtains oxygen dissolving value accurately.When the satisfied setting of dissolved oxygen in water value requires; The air pump relay control module is opened air pump, and Xiang Shuizhong imports oxygen, till oxygen dissolving value meets the demands; Key-press module is provided with corresponding dissolved oxygen threshold values, and display module shows current oxygen dissolving value concentration correlation parameter.
The beneficial effect of the utility model is, improves the water body environment of freshwater aquiculture, thereby improved the survival rate of freshwater aquiculture, and the practical application effect of aspect such as culture benefit, have advantages of high practicability.
