Problems solved by technology

[0006] 1. The use of propeller propellers interferes and damages marine organisms such as fish schools, and destroys the underwater ecological environment. The existing ones have high energy consumption and complicated control, and are not suitable for aquaculture.
[0007] 2. The buoyancy drive method generally adopts the oil bladder type drive. Although the energy consumption is low, there is a risk of oil leakage to pollute the water environment, and the structure is complex and the volume is large
[0008] 3. GPRS, satellite communication, and short-wave radio are mostly used in the existing coastal waters. GPRS and satellite communication are expensive and consume a lot of energy; the short-wave radio has a long transmission distance but a single networking method and a small number of channel support nodes, which is not suitable for large-scale detection. network application

Embodiment 1

[0047] Such as figure 1As shown, a low-cost offshore aquaculture water quality monitoring system includes a pressure-resistant cabin 7, a Kevlar cable 11, a cable reel 13, a DC geared motor 12, and a gravity anchor block 14; wherein, the outside of the pressure-resistant cabin 7 is equipped with solar energy battery board 6, communication antenna 1, pressure sensor 2, temperature sensor 4, salinity sensor 5 and dissolved oxygen sensor 3;

[0048] a solar panel 6 configured to charge the rechargeable battery pack 10;

[0049] The communication antenna 1 is configured to transmit the collected data to the control center 15;

[0050] A pressure sensor 2, a temperature sensor 4, a salinity sensor 5, and a dissolved oxygen sensor 3 are configured to measure hydrological data of the entire water depth profile;

[0051] The interior of the pressure chamber 7 is equipped with a rechargeable battery pack 10, a power board 8 and a control and data acquisition board 9;

[0052] A rech...

Embodiment 2

[0060] On the basis of above-mentioned embodiment 1, the present invention also mentions a kind of low-cost off-shore aquaculture water quality monitoring method, specifically comprises the following steps:

[0061] Step 1: Arrange the system in a sea area where the water depth does not exceed 20 meters;

[0062] Step 2: The control and data acquisition board controls the DC geared motor to drive the cable reel to rotate forward and pull the pressure chamber to the bottom of the sea. During the dive of the pressure chamber, the temperature sensor continuously measures the temperature of each water depth, and the salinity sensor continuously measures each water depth. The salinity and dissolved oxygen sensors of the water depth continuously measure the dissolved oxygen of each water depth, and store the data in the card through the built-in SD card of the control and data acquisition board;

[0063] Step 3: When the pressure chamber dives to the preset depth, the control and da...

Abstract

The invention discloses a low-cost offshore aquaculture water quality monitoring system and method, and belongs to the technical field of water quality monitoring. A pressure-resistant bin is draggedby a cable and an anchor block to float up and sink down, data of each sensor is collected on different water depth surfaces, the collected water quality data is sent to a data center of a monitoringplatform after water is discharged, and a real-time monitoring result is published through a website after storage, analysis and processing. The system can realize real-time monitoring of profile water quality in the field of offshore aquaculture, and has the advantages of simple structure, long transmission distance, low cost and power consumption, capability of meeting large-scale deployment, capability of realizing profile hydrological data measurement and the like. The cable winding device is used for achieving measurement of profile data under the whole water depth, the laying number of sensors is reduced, and the spatial resolution of hydrological data is improved. A wireless sensor network is established based on a 6LoWPAN scheme, and the number of nodes is increased.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to a low-cost offshore aquaculture water quality monitoring system and method. Background technique [0002] Real-time monitoring and regulation of water quality is a key link in the aquaculture process and an important measure to ensure the quality of aquatic products. Among them, real-time online water quality monitoring, multi-parameter sensors and low-power remote communication technology are the mainstream development directions. [0003] At present, the water quality monitoring in the breeding area is based on buoys and land monitoring base stations. The former realizes the water quality monitoring of the water body by deploying a large number of small buoys in the breeding area, and the latter realizes water quality and meteorological monitoring by deploying their own water quality monitors on the shore. Monitoring of parameters. Due to the varie...
