Embodiment 1

[0074] The cultivation pool is a rectangular structure with an area of ​​20 mu, and the depth of the pool should be more than 5 meters. Sand the bottom of the pool 15 cm.

[0075] like figure 1 The shown embodiment is a monitoring device for the culture fluid of Portunus crab seedlings, including a control terminal 1 and 5 first terminals and 3 second terminals located above the culture tank; the control terminal includes a main controller 3, a memory 2, a second terminal A wireless transceiver 4, water depth sensor 20, first display 5, alarm 6, first computer 18, the first solenoid valve 17 located on the water inlet pipe of the cultivation tank and the second electromagnetic valve 17 located on the water outlet pipe of the cultivation tank Electromagnetic valve 16; the main controller is electrically connected to the memory, the first wireless transceiver, the water depth sensor, the first display, the alarm, the first computer, the first electromagnetic valve and the secon...

Embodiment 2

[0112] Embodiment 2 comprises all structures and step parts in embodiment 1, also comprises the following steps in embodiment 1:

[0113] Set the standard range of the pH sensor to [R 1 , R 2 ], the main controller obtains t i-d time to current time t i The curve S(t) of the mean value detected by the pH sensor, t i-d for t i At the previous moment, the time difference between the two is d; the volatilization and decomposition threshold SNR is pre-stored in the memory w ;

[0114] The main controller inputs S(t) into the stochastic resonance model pre-stored in the memory middle;

[0115] Among them, x(t) is the displacement of the vibrating particle, Ω is the angular frequency, f 0 is the signal frequency, A is a constant, r and ω are the set attenuation coefficient and the frequency of the linear vibration particle respectively, c is the set signal modulation coefficient, b is the set secondary noise ξ 2 (t) coefficient, ξ(t) is trichotomous noise, ξ(t)∈{-a, 0, a},...

Abstract

The invention discloses a portunid juvenile culture solution monitoring device and control method. The portunid juvenile culture solution monitoring device comprises a control end, and m first terminals and n second terminals which are respectively arranged above culture ponds, wherein n is smaller than m. The control end comprises a main controller, a memory, a first wireless transceiver, a water depth sensor, a first display, an alarm, a first computer, first solenoid valves respectively arranged on water inlet pipes of the culture ponds, and second solenoid valves respectively arranged on water outlet pipes of the culture ponds. Each first terminal comprises a terminal controller, a second wireless transceiver, a second display, a second computer, and a dissolved oxygen sensor, a PH value sensor, a water temperature sensor and a turbidity sensor which are arranged in a culture solution. Compared with the first terminal, each second terminal is additionally provided with an oxygen supplying pump. The portunid juvenile culture solution monitoring device can automatically monitor the parameter changes of the culture solution in the culture ponds, automatic adjustment is carried out in time once some parameters are abnormal, and alarm information for the parameters needing manual intervention is emitted out in time.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a monitoring device and a control method for the culture fluid of swimming crab seedlings which can provide a reliable basis for the healthy growth of swimming crab seedlings. Background technique [0002] Portunus trituberculatus, scientific name Portunus trituberculatus, belongs to the family Portunidae, decapod order, and the genus Portunus. Distributed in China's Liaoning, Hebei, Tianjin, Shandong, Jiangsu, Zhejiang, Fujian and other sea areas. Generally, from south to north, March to May and September to October are the peak production seasons, and the Liaodong Peninsula in Bohai Bay produces more in April to May. Portunus trituberculatus is one of the most important export products in China, mainly exported to Japan, Hong Kong, Macao and other countries and regions. [0003] Swimming crabs grow rapidly and are highly profitable, and have become an impo...
