Embodiment Construction

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] In view of the problems that the aforementioned existing automatic aerators have high investment costs and high maintenance costs, which are not conducive to the popularization of automatic aerators, the present invention arranges the MEMS air pressure sensor around the container to be detected to detect the air pressure around the container. Detect the temperature, and then connect the MEMS air pressure sensor to the control system, and control the startup or shutdown of the aerator through the control system, so as to realize automatic aeration of the water in the container to be detected, with low cost and good effect. This is conducive to the popularization of automatic aerators.

Abstract

The invention provides an automatic oxygen-increasing device and method based on an MEMS gas pressure sensor, wherein the device comprises an oxygen-increasing machine arranged in a to-be-detected container, a control system connected with the oxygen-increasing machine, and the MEMS gas pressure sensor connected with the control system; the MEMS gas pressure sensor is arranged around the to-be-detected container and is used for detecting the gas pressure and the temperature around the to-be-detected container; the MEMS gas pressure sensor sends the detected gas pressure and temperature values around the to-be-detected container to the control system, and the control system obtains the oxygen capacity of water in the to-be-detected container according to the gas pressure and temperature values and controls starting or closing of the oxygen-increasing machine according to the oxygen capacity. Through the device and the method, the water in the to-be-detected container can be automatically subjected to oxygen increasing, the cost is low, the effect is good, and popularization of the automatic oxygen-increasing device is facilitated.

Description

Technical field [0001] The invention relates to the technical field of oxygen supply in fish ponds, and more specifically, to an automatic oxygen increase device and method based on a MEMS air pressure sensor. Background technique [0002] Many occasions in daily life, such as household fish tanks, fish ponds in the aquaculture industry, etc., have clear requirements for the oxygen capacity in the water. This requires fish farmers to detect the oxygen capacity in the water in time to facilitate timely monitoring of the oxygen capacity in the water. The oxygen capacity is replenished. [0003] At present, the commonly used method is to use an electrochemical dissolved oxygen meter to detect the oxygen capacity in the water. Its working principle is: oxygen is reduced by the working electrode through the diaphragm, and a diffusion current proportional to the oxygen concentration is generated. By measuring this current, the concentration of dissolved oxygen in the water is obtained. ...
