Problems solved by technology

[0003] In the prior art, the measurement of the transparency of the water body usually adopts the Sephardt disk method, the Sephardt disk is a pure white or black and white disc, which is used to measure the water transparency in the water body, and the disc is fixed on a rope. Slowly descending into the water, the observer observes the disappearance of the disc, and counts it. The length of the submerged rope is regarded as the transparency of the sea water. This measurement method is greatly affected by the subjectivity of the observer, weather conditions, and most importantly, Can't be done continuously, can't get real-time data, can't measure on a large scale

Embodiment 1

[0043] This embodiment discloses a drifting type seawater transparency automatic measuring device, such as Figure 1-2 as shown, figure 1 is the front view of the measuring device, figure 2 It is a top view of the measuring device. It can be seen that the automatic measuring device for seawater transparency in this embodiment includes a support frame 3, a sealed shell 5, a light attenuation channel 11 and a communication antenna 10, such as Figure 7 As shown, the support frame 3 includes an upper support frame 31 and a lower support frame 32, the upper support frame 31 and the lower support frame 32 are two conical structures, the bottoms of the upper support frame 31 and the lower support frame 32 are fixedly connected, and the upper support frame 31 and the lower support frame 32 are fixedly connected. The control module 1, the solar panel 2 and the communication antenna 10 are sealed and installed in the frame 31. The solar panel 2 supplies power for the measuring device...

Embodiment 2

[0067] In this embodiment, on the basis of Embodiment 1, a liquid flow sensor is installed at the one-way water outlet valve, and the liquid flow sensor is connected to the control module to monitor the flow rate of liquid exchange at the one-way water outlet valve. In the measurement preparation stage, the total flow of liquid passing through the one-way outlet valve can be monitored through the control module. When the total flow of liquid reaches the capacity of the light attenuation channel, it indicates that the water sample in the light attenuation channel is a new water sample.

[0068] In the actual measurement process, the specific steps in the measurement preparation stage are:

[0069] Step 1.1, the automatic measuring device reaches the designated position, and the ultraviolet lamp is turned on regularly;

[0070] Step 1.2, GPS obtains the latitude and longitude information of the measurement position, and transmits the above information to the PIC controller;

Abstract

The invention discloses a drifting type seawater transparency automatic measuring device and transparency measuring method.The drifting type seawater transparency automatic measuring device comprises a supporting frame, a sealing shell, a light attenuation channel and a communication antenna, a power supply module and a control module are installed above the supporting frame, and the control module comprises a controller, a GPS module and a communication module; the two ends of the light attenuation channel are respectively provided with a light sensor, a light intensity collecting and receiving module and an LED lamp to form a detection module. Transparency analysis performed by adopting the device comprises measurement preparation, light intensity measurement and transparency analysis calculation, the light intensity is transmitted to the controller through the light intensity acquisition and receiving module, and the transparency is calculated according to the light intensity through a regression inversion analysis algorithm. The method is high in measurement accuracy; solar energy is used for supplying power, and the seawater transparency can be continuously and automatically monitored for a long time along with the drifting of ocean current; by arranging the ultraviolet lamp, the light attenuation channel, the LED lamp and the light sensor can be killed, and the situation that the test result is affected due to attachment of microorganisms is avoided.

Description

technical field [0001] The invention relates to the technical field of ocean detection, in particular to a drifting automatic seawater transparency measurement device and a transparency measurement method. Background technique [0002] Seawater transparency indicates the degree of seawater light transmission, that is, the attenuation degree of light in seawater. It can represent the clarity of ocean water and is an intuitive ocean optical parameter. The observation of seawater transparency plays an important role in ensuring the safety of transportation, maritime operations, aquaculture, etc. For example, the high transparency of seawater makes it possible for us to avoid hidden reefs or dangerous obstacles. Studying the transparency of seawater is also of certain significance for the fish farming industry. For example, the cultivation of abalone and sea cucumber requires high transparency of seawater, while the cultivation of razor clams and oysters requires low transparenc...
