Real-time sucrose content detection method and device

Abstract

The invention relates to a real-time sucrose content detection method and device, and the method comprises the steps of placing an object to be detected in a high-frequency electromagnetic field and getting the sucrose content in the object to be detected according to the frequency change. A sucrose content detection sensor of the device is an excitation source circuit which can generate 600K-1MHz sine wave excitation signals, and the sucrose content detection sensor is connected with a data acquisition circuit and a micro-processor. The micro-processor stores a conversion program between sugar content and frequency change increment. The sensor approaches or contacts the outer skin of sugarcane and then the sucrose content in the detected object can be obtained. The device is further equipped with a solution sucrose content detection sensor which comprises an excitation source circuit capable of generating 1-6MHz sine wave excitation signals and a sucrose solution sample tube, and the sample tube is positioned at one end of an inductor coil of the excitation source circuit. The two sensors are connected with the data acquisition circuit via a two-way switch. The two-way switch is used for selecting the sensor to be used, and a selection button is used for selecting the detection mode of a function menu. All the parts of the device are mounted in a housing. By adopting the device and the method, the non-destructive real-time detection of sucrose content can be realized, the precision is high, the use is simple and convenient and the cost performance is high.

Description

(1) Technical field [0001] The invention relates to the technical field of sucrose content detection, in particular to a real-time detection method and device for sucrose content in sugarcane or solution using high-frequency electromagnetic waves. (2) Technical background [0002] The sugar industry is an important industry related to the national economy and people's livelihood, and sucrose is the main component of it. However, the problem of scientific calibration and pricing during sugarcane purchase has not been well resolved, which directly affects the income of the majority of sugarcane farmers, and also makes it difficult for businesses to determine the best time to purchase. Therefore, it is particularly important to determine the quality, price and industrial processing time of sugarcane by measuring the sugar content of sugarcane. [0003] There are many methods for measuring sugar content, including chemical methods, physical methods, etc. Although chemical metho...

However, the problem of scientific calibration and pricing in the purchase of sugarcane has not been well resolved, which directly affects the income of the majority of sugarcane farmers, and also makes it difficult for merchants to determine the best time to purchase

However, the needle-shaped sensor needs to be pierced into the sugarcane skin or soaked in the solution to obtain the sugar content value, which is labor-intensive and time-consuming for a large number of detections, and also causes damage to the sugarcane
