A system and method for measuring water environment parameters on board a ship

Abstract

The invention provides shipborne underway water environment parameter measurement system and method. The shipborne underway water environment parameter measurement system comprises a sampling module 1, a flow measurement module 2, a measurement chamber 3, a water sample measurement module 4, a control protection module 5, a GPS (global position system) module 6, a power supply module 7 and a data processing and display system 8, wherein an overflow port 9 and an exhaust port 10 are respectively formed in the top and the bottom of the measurement chamber 3; an exhaust valve 11 is arranged at the exhaust port. By adopting the data processing and display system 8, the data obtained by the GPS module 6 and the flow measurement module 2 can be utilized to calculate sampling flow velocity in real time, so that accurate track data are obtained; efficient real-time measurement of water space information is achieved. The shipborne underway water environment parameter measurement system and method are simple and convenient to operate, and high in measurement accuracy, and have good versatility and expandability.

Description

technical field [0001] The invention relates to the technical field of water body measurement, in particular to a system and method for measuring water environment parameters carried by a ship. Background technique [0002] In recent years, my country's lakes are facing a series of problems such as shrinking area, deteriorating water quality, severe damage to the ecological environment, and declining functions and benefits, which shows that the water ecological environment problems accumulated by my country's rapid economic growth have begun to enter a period of concentrated outbreaks. . The rapid monitoring and protection of lake water environment has become an important requirement for maintaining the sustainable use of lake functions. Rapid measurement of water environment parameters is a necessary condition for monitoring and protecting water environment. [0003] At present, the water environment parameters that are concerned mainly include suspended sediment concentra...

AI Technical Summary

Problems solved by technology

[0005] 1. Sampling laboratory measurement and fixed-point in-situ measurement methods have problems such as limited measurement range, insufficient representation of sample space, inability to reflect the characteristics of natural water environment parameters in real time, and low measurement efficiency.

[0006] 2. The towed navigation measurement method is affected by factors such as wind and waves, the length of the towing cable, etc., resulting in the results of the water body parameters on the navigation profile not being on the horizontal plane; in addition, the disturbance of the ship's power to the water body will also cause a large number of air bubbles in the measured water body area , which interferes with the transmission of the optical path of the equipment, resulting in errors in the measurement results

In addition, in the towed measurement, because the matching of ship speed and equipment sampling frequency has not been well solved, it is easy to have problems such as difficult to restore the spatial position of sampling data, and undefined sampling spatial resolution.
