DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] According to an embodiment of the present invention, the three-dimensional monitoring system for particle size in oil includes a detection tube 12, a light source and an image processor 11. The detection tube 12 has a detection cavity for accommodating the oil to be detected. The light source includes an X-axis laser source 1, a Y-axis laser source 2 and a Z-axis laser source 3. The X-axis photoelectric receiver 4 and the X-axis laser source 1 are located on both sides of the detection tube 12 in the X-axis direction. The Y-axis photoelectric receiver 5 and the Y-axis laser source 2 are correspondingly located on both sides of the detection tube 12 in the Y-axis direction. The Z-axis photoelectric receiver 6 and the Z-axis laser source 3 are correspondingly located on both sides of the detection tube 12 in the Z-axis direction. The lasers emitted by the X-axis laser source 1, the Y-axis laser source 2 and the Z-axis laser source 3 intersect in the detection cavity. The photoelectric converter corresponds to the X-axis photoelectric receiver 4, the Y-axis photoelectric receiver 5 and the Z-axis photoelectric receiver 6 to convert the optical signals received by the X-axis photoelectric receiver 4, the Y-axis photoelectric receiver 5 and the Z-axis photoelectric receiver 6 into electrical signals. The image processor 11 is electrically connected to the photoelectric receiver to calculate and process the electrical signals. The present application forms a cross light source through a three-dimensional light source arrangement to enable three-dimensional testing of particles in oil with higher accuracy.

[0020] The three-dimensional monitoring system for particle size in oil according to the embodiment of the present invention has the advantages of accurate and high precision in counting particles in oil. In some embodiments, the detection tube 12 is a U-shaped tube, which includes an inlet section 121, a detection section 122 and an outlet section 123 connected in sequence, the inlet section 121 is provided with an oil inlet 14, the outlet section 123 is provided with an oil outlet 15, the detection section 122 extends along the Z-axis direction, and the inlet section 121 and the outlet section 123 extend along the X-axis direction.

[0021] Specifically, the inlet section 121 and the outlet section 123 of the U-shaped tube are parallel to each other. After the oil enters the inlet section 121 from the oil inlet 14, it flows into the detection cavity of the detection section 122, and is subjected to three-dimensional laser irradiation in the detection cavity for particle size testing. After the test is completed, the oil enters the outlet section 123 and finally flows out from the oil outlet 15.

[0022] In some embodiments, the X-axis laser source 1 and the Y-axis laser source 2 are arranged in the radial direction around the detection section 122, the X-axis photoelectric receiver 4 and the Y-axis photoelectric receiver 5 correspond to the detection section 122 separated by the X-axis laser source 1 and the Y-axis laser source, the Z-axis laser source 3 is located at one end of the exit section 123 connected to the detection section 122, the Z-axis photoelectric receiver 6 is located at one end of the entrance section 121 connected to the detection section 122 to correspond to the Z-axis laser source 3, and the lasers emitted by the X-axis laser source 1, the Y-axis laser source 2 and the Z-axis laser source 3 intersect at one point.

[0023] Specifically, the two laser sources of the X-axis and the Y-axis are arranged on the same Z-axis plane, the X-axis laser source 1 and the X-axis photoelectric receiver 4 are located on both sides of the detection section 122 to allow the laser to pass through the detection cavity of the detection section 122, the Y-axis laser source 2 and the Y-axis photoelectric receiver 5 are similar, the position of the Z-axis laser source 3 is located at the projection position of the detection section 122 at the exit section 123, and the position of the Z-axis photoelectric receiver 6 is located at the projection position of the detection section 122 at the entrance section 121. Optionally, the position of the laser source can be swapped with the position of the photoelectric receiver. At this time, the scattered light generated by the laser sources in other axes irradiating the particles in the detection cavity is deemed to have no effect on the photoelectric receiver.

[0024] In some embodiments, the three-dimensional monitoring system for particle size in oil further includes a flow meter 13 , which is arranged on the detection tube 12 to measure the flow rate of oil passing through the detection tube 12 .

[0025] Specifically, the flow meter 13 is a precision flow meter 13 , and the flow meter 13 is arranged at the oil inlet 14 of the detection tube 12 .

[0026] In some embodiments, a temperature sensor is also included to measure the temperature of the oil in the detection chamber, and a flow rate sensor is also included to measure the flow rate of the oil in the detection chamber.

[0027] Specifically, the temperature sensor and flow rate sensor are convenient for analyzing the detection environment and oil state in the detection chamber. A more detailed numerical change curve of the oil can be obtained based on the real-time measured temperature and flow rate. When the oil sample remains unchanged, the environmental parameters in the detection chamber are changed to obtain the output signal of the particle sensor under different environmental parameters. The relationship between the environmental parameters and the output signal is fitted by a computer. The data can be corrected to effectively compensate for the measurement error caused by the environmental change and improve the reliability of the system.

[0028] In some embodiments, a measurement host is further included, and the measurement host is electrically connected to the image processor 11 to store data.

[0029] Specifically, the measuring host can store various measured data to facilitate recording and analysis of oil particle size.

[0030] In some embodiments, the measurement host further includes a display, and the display is used to display the image processed by the image processor 11 .

[0031] Specifically, the display shows the image processed by the image processor 11 to realize the display of the number, size and three-dimensional structure of the particles 16, which enables the user to analyze the particles in the oil more intuitively.

[0032] In some embodiments, the photoelectric converter is electrically connected to the image processor 11 through the data transmission line 10. The photoelectric converter includes an X-axis photoelectric converter 7, a Y-axis photoelectric converter 8, and a Z-axis photoelectric converter 9, which are electrically connected to the image processor 11 through the data transmission line 10, respectively.

[0033] Specifically, the transmitted light received by the photoelectric receiver enters the sensor and is converted into a voltage signal by the photoelectric converter. The voltage signal is amplified and filtered, and then converted into a digital signal by the image processor 11, and then output and displayed on the display screen. The data transmission line 10 enables stable signal transmission between the photoelectric converter and the image processor 11.
