Embodiment Construction

[0020] The principle block diagram of the cotton fiber moisture detection system of the present invention is shown in Fig. 1 . The signal generator acts on the capacitance sensor, and connects the capacitance, temperature, and Hall linear sensors to the data conditioning circuit module, and then transmits them to the host computer through the data acquisition card.

[0021] 1. Signal generator module:

[0022] When the frequency is 10KHz~20KHz, the instrument responds most sensitively to the change of moisture contained in the fiber, and when the frequency is 10KHz, the reproducibility and stability of the test results of the instrument are the best, so the signal generator with a frequency of 10kHz is selected, in order to ensure The stability of the signal generator ensures the accuracy of the test results. According to the principle of using integrated circuits as much as possible, the high-frequency waveform generator MAX038 produced by MAXIM Company is selected.

Description

1. Technical field [0001] The invention belongs to a cotton fiber moisture measuring instrument, in particular to a capacitive-resistance intelligent cotton fiber moisture measuring system based on data fusion and virtual instruments. 2. Background technology [0002] The moisture content of cotton fiber is a key parameter affecting the quality of cotton processing, and it is also an important control reference in the cotton processing quality monitoring system. Cotton moisture determination methods can be divided into two categories: direct method and indirect method. Because the indirect method has the characteristics of rapid and continuous determination, it has been continuously developed over the years and is the mainstream of cotton moisture measuring instruments at home and abroad. Typical cotton moisture indirect measuring instruments include microwave, infrared, CCD (black and white camera), capacitive and resistive. [0003] In the field of cotton testing instrum...
