Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, and the advantages and characteristics of the present invention will become clearer along with the description. However, these embodiments are only exemplary and do not constitute any limitation to the scope of the present invention. Those skilled in the art should understand that, without departing from the spirit and scope of the present invention, equivalent modifications or substitutions can be made to the details and forms of the technical solutions of the present invention, and these modifications and substitutions should fall within the protection scope of the present invention .

[0049] We know that according to the Beer-Lambert law, when the parallel light beam emitted by the light source propagates in water, the light intensity received by the water body, the light intensity emitted by the light source, the turbidity of the water body,...

Abstract

The invention relates to a continuous monitoring method and device for the turbidity of a water body, which are suitable for underwater long-period water quality monitoring. Starting from the aspect of invariable light intensity received by a sensor, by adjusting the distance between a light source and the sensor or the emitted light intensity of the light source, the method can calculate the turbidity of the water body based on a Beer-Lambert law. The device basically comprises the light source, a light intensity sensor, a single chip microcomputer, a slide rod, a light source moving mechanism (or a light intensity sensor moving mechanism), a wireless signal transmitter, a wireless signal receiver and a data processing system. The device can be put into the wild water body for long time to continuously determine the turbidity of the water body; in a determination process, the position of the light source or the sensor, and the intensity of the light source can be adjusted in real time according to the change of the turbidity of the water body; a relation between the turbidity value of the water body and the measuring distance, and a relation between the turbidity value of the water body and the intensity of the light source are utilized to carry out long-time field monitoring on the turbidity of the water body, so as to really reflect an actual change condition of the water body; a monitoring process is accurate and reasonable.

Description

technical field [0001] The invention relates to water turbidity monitoring technology, in particular to a monitoring method and device suitable for long-term continuous monitoring of field water turbidity. Background technique [0002] Turbidity is used to indicate the clarity or turbidity of water. It is an expression term for the optical properties of water samples. It is related to the mass concentration of suspended solids, particle size, shape, and refractive index. The more suspended solids, the greater the turbidity. . The size of turbidity can reflect the degree of pollution of the water body to a considerable extent, and it is one of the important monitoring indicators to measure the water quality at present. [0003] The turbidity of tap water should be expressed in scattered turbidity unit NTU, which should not exceed 3NTU, and should not exceed 5NTU under special circumstances. The turbidity of many process waters is also important. Beverage plants, food proce...
