Problems solved by technology

[0004] Most of the existing dissolved oxygen sensors adopt single-point arrangement or multi-point arrangement, and the installation position of the sensor cannot be arranged reasonably. It is impossible to comprehensively evaluate the water quality simply by relying on the arrangement of single-point sensors in the horizontal area. Combining the detection data of the vertical direction with the detection data of the vertical direction, it is impossible to consider and analyze the breeding environment from the vertical and plane perspectives, to ensure that the entire water area can have a reasonable amount of dissolved oxygen, to solve the effect of water depth on dissolved oxygen, and to effectively discover the Prevents the formation of oxygen debts that prevent the system from functioning effectively

Embodiment 1

[0065] A system for measuring oxygen and increasing oxygen, comprising an oxygen increasing machine 1, a mobile carrier 2 on water and an underwater carrying frame 3, such as figure 1 The feeding ship in the aquaculture can be used as the mobile carrier 2 on water. A lifting motor 4, a processor and a timer are set on the above-water mobile carrier 2, and the processor controls the lifting motor 4 through a digital signal; a traction rope 5 is fixed on the underwater carrier 3, and the The top is connected to the lifting motor 4, and the underwater carrying frame 3 is provided with a dissolved oxygen sensor and a water temperature sensor, and the dissolved oxygen sensor, the water temperature sensor, and the timer are all connected to the signal input end of the processor. A power supply battery 21 and a solar panel 22 are arranged on the feeding ship, and the solar panel 22 is connected to the power supply battery 21. Preferably, the feeding ship is provided with a driving mo...

Embodiment 2

[0067] Oxygen control method:

[0068] Step 1: a) When selecting points on the same horizontal plane, take 10 meters as an interval point and take it as P 1 , P 2 ......P i , when selecting points in the vertical direction, take 0.5 meters as an interval point, and take it as H 1 , H 2 ......H n , define the coordinates (P i , H n ); the underwater carrier 3 is controlled to move in the horizontal direction by the water mobile carrier 2, and the lifting motor 4 controls and adjusts the length of the traction rope 5 to realize the adjustment of the height of the underwater carrier 3 from the water surface, and the control of the underwater carrier 3 according to a certain move in sequence, such as by image 3 According to the method of moving from top to bottom and horizontally, then from bottom to top and from top to bottom, multi-point measurement is realized with a single-point sensor, until all the measurement points in the water area are selected, the dissolved oxyg...

Abstract

The invention discloses an oxygen measurement and oxygenation system and a method for oxygenation control thereof. The oxygen measurement and oxygenation system includes an aerator, an overwater mobile carrier and an underwater bearing frame. The signal output end of a processor is connected with the aerator through an electromagnetic switch. The overwater mobile carrier is provided with a liftingmotor, a processor and a timer. A pulling rope is fixed to the underwater bearing frame, the top of the pulling rope is connected to the lifting motor, and the underwater bearing frame is provided with a dissolved oxygen sensor and a water temperature sensor. The dissolved oxygen sensor, the water temperature sensor and the timer are connected with the signal input end of the processor. The oxygen measurement and oxygenation system has the advantages that closed loop linkage control is performed on the aerator according to changes of water temperature and dissolved oxygen, and real-time collection and control over water quality are performed more effectively.

Description

technical field [0001] The invention mainly relates to the field of aquaculture, in particular to an oxygen measuring and oxygen increasing system and an oxygen increasing control method of the system. Background technique [0002] Dissolved oxygen is a main limiting factor for the growth of aquatic organisms, and it is also the factor that people pay the most attention to in aquaculture. Insufficient dissolved oxygen content will make aquatic organisms grow slowly, have low resistance, and even lead to the death of organisms in severe cases. Therefore, the detection and control method of dissolved oxygen in water is very important for aquaculture. [0003] Water temperature plays a key role in aquaculture. Due to the large temperature difference and density difference between the upper and lower water layers, it is easy to form stratified sites. Especially in autumn, winter and summer, after the formation of stratification in summer and autumn, the upper and lower water la...
