Problems solved by technology

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
Therefore, when the DC excitation electrical measurement method is used to measure the sugar content of sugar cane or sucrose solution, it is affected by the unstable biological characteristics of sucrose, and the error of the measurement result is relatively large.
At present, there is no satisfactory detection result, which can carry out real-time detection method and online detection device for sugarcane or sucrose solution

Embodiment 1

[0021] This example uses this method to detect the sugar content of sucrose solution. Such as figure 1 The sensor composed of a pair of electrodes is inserted into the sucrose solution, the sensor is connected to the pulse excitation signal generating circuit, the sensor is connected in series with a voltage dividing resistor, the voltage signal of the voltage dividing resistor is amplified and then connected to the microprocessor module, and the output terminal of the microprocessor module is connected to monitor. The microprocessor module includes an operational amplifier circuit, which stores electrical signal relationship data and processing programs generated under the action of pulse signals with different sugar contents in the sucrose solution. The microprocessor module controls the pulse excitation signal generation circuit, and when the sugar content is below 8%, a 500Hz pulse signal is generated, and when the sugar content is above 8%, a 5kHz pulse signal is generat...

Embodiment 2

[0026] This example uses this method to detect sugar cane content. Similar to Example 1, such as figure 1 As shown, the sensor is inserted into the sugarcane sample, and the microprocessor module stores the electrical signal relationship data and processing program generated by the different sugar content of the sugarcane under the action of the pulse signal. The microprocessor module controls the pulse excitation signal generation circuit, and when the sugar content is below 8%, a 500Hz pulse signal is generated, and when the sugar content is above 8%, a 5kHz pulse signal is generated.

[0027] Table 2 shows the results of this method for detecting the sugar content of multiple sugarcane samples, and lists the results of the optical rotation method after the sugarcane juice of the same sample is squeezed. It can be seen that the results of this method for detecting sugarcane sugar content are stable, and the error is small, which is different from that of the optical rotation...

Abstract

This invention relates to sugar content real time test method micro processor by impulse excitation signal by 50 to 10kH to test sugar liquid or sugar content with different of test object content with different resistance and voltages to get sugar content. This invention method is free from biological electrical field attuning change impact by use of random measurement method to exert different frequency impulse signals to improve test accuracy.

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 on-line detection device for sucrose content in sugarcane and sucrose solution using electrical pulse excitation signals. (2) Background technology [0002] The sugar industry is an important industry related to the national economy and the people's livelihood, and sucrose is its main component. 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. 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 and physical methods...
