Embodiment Construction

[0019] specific implementation plan

[0020] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0021] Such as figure 1 As shown, a design and method of an integrated dissolved oxygen analyzer device is characterized in that it includes the following steps:

[0022] (1) In order to improve the detection accuracy of the dissolved oxygen content in water, the present invention adopts the fluorescence method to measure the dissolved oxygen content in water. Therefore, a new dissolved oxygen measurement method with higher precision and more stability than the traditional measurement method is obtained, which makes up for the shortcomings of the traditional measurement method.

[0023] (2) The probe part is composed of special coatings (containing special fluorescent substances), optical signal generating LEDs, lenses, photocouplers and temperature sensors and other components (such as figure 2 shown). The blue LED produ...

Abstract

The invention discloses an integrated dissolved oxygen analyzer and a method. The analyzer comprises probe, sensing and control parts. The method provided in the invention comprises the following steps of: submerging the probe part which is provided with an optical device as the main body thereof in water, performing a series of conversion processing and then transmitting an electric signal obtained through conversion to the main body part; and performing the courses of correction, conversion, processing and the like on the signal transmitted from the probe part, and completing communication with the control part. Besides, the sensing part is designed with two acquisition and conversion manners which can be also multiplexed. The integrated dissolved oxygen analyzer has the advantages of small volume, high integration level, low power consumption, low cost, good adaptability to multi-point networking and the like, and also has complete functions and rich interfaces; therefore, the integrated dissolved oxygen analyzer is completely capable of meeting the requirements of dissolved oxygen content and temperature detection in water under complex conditions.

Description

technical field [0001] The invention relates to the design and method of an integrated dissolved oxygen analyzer device, which can be used for water quality detection, and can flexibly and accurately measure dissolved oxygen content and temperature in water. Background technique [0002] As an important water quality index, dissolved oxygen plays an important role in both water quality evaluation and scientific research. How to determine the concentration of dissolved oxygen accurately, continuously and rapidly has always been an important topic in analytical chemistry. Therefore, the method of using chemical theory and means to detect dissolved oxygen first appeared in the field of chemistry, and such methods are called chemical methods. With the continuous development of other disciplines and technologies, the instrumental method derived from the combination of various disciplines has gradually become a hot spot in the field of dissolved oxygen concentration detection in ...
