[0048] Wherein, the reflection unit is connected to the measurement cavity unit; the measurement cavity unit is connected to the light source unit and to the spectrum unit; the light source unit is connected to the control transmission unit; the spectrum unit is connected to the control transmission unit; the control transmission unit is connected to the display analysis unit;

[0049] The light source unit is used to emit a broad-spectrum light beam and irradiate the broad-spectrum light beam into the measuring cavity unit, so that the broad-spectrum light beam passes through the sample in the measuring cavity unit and irradiates the reflecting unit;

[0050] The reflection unit is used to reflect the broad spectrum light beam after passing through the sample into the spectrum unit;

[0051] The spectral unit is used to measure the spectral change data of the lubricating oil after aging according to the wide-spectrum light beam after passing through the sample, and transmit the spectral change data to the display analysis unit through the control transmission unit;

[0052] The display analysis unit is used to perform calculation analysis on the spectral change data, so that the system can monitor the aging degree of the lubricating oil according to the calculation analysis results of the lubricating oil.

[0053] In this embodiment, the reflection unit is connected to the measurement cavity unit, the measurement cavity unit is connected to the light source unit through an optical fiber, and the measurement cavity unit is connected to the spectrum unit through an optical fiber, and the light source unit and the spectrum unit are connected to the spectrum unit respectively. After receiving the monitoring instruction, the light source unit emits a broad spectrum light beam, and irradiates the broad spectrum light beam into the measurement cavity unit connected to the light source unit. Furthermore, the measurement cavity unit has a sample, so the purpose of the light source unit irradiating the broad spectrum light beam into the measurement cavity unit is to make the broad spectrum light beam pass through the sample in the measurement cavity unit and irradiate on the reflection unit connected to the measurement cavity unit.

[0054] Further, the reflection unit reflects the broad spectrum light beam after passing through the sample into the spectrum unit connected to the measurement cavity unit. After receiving the broad spectrum light beam after passing through the sample reflected by the reflection unit, the spectrum unit measures the spectrum change data of the lubricating oil after aging according to the broad spectrum light beam after passing through the sample. Further, the spectrum unit includes a dispersion component and a linear array detector, referring to Figure 2 As shown, Figure 2 It is a schematic diagram of the structure of the spectrum unit provided in this application.

[0055] The dispersion components in the spectrum unit may include but are not limited to gradient filters, gratings, prisms and quantum dot filters. The dispersion components can perform spectroscopic processing on the incident light beam, that is, the gradient filters, gratings, prisms and quantum dot filters can perform spectroscopic processing on the incident light beam, and the linear array detector can convert the spectroscopically processed incident light beam into an electrical signal. In other words, the structure of the spectrum unit can be a combination of a gradient filter and a linear array detector, a combination of a grating and a linear array detector, a combination of a prism and a linear array detector, or a combination of a quantum dot filter and a linear array detector.

[0056] Furthermore, for ease of understanding, this embodiment is described by taking a combination of a gradient filter and a linear array detector as a spectral unit.

[0057] It can be further understood that the reflection unit reflects the wide-spectrum light beam after passing through the sample into the spectral unit, and the gradient filter and the linear array detector in the spectral unit measure the spectral change data of the lubricating oil after aging based on the wide-spectrum light beam after passing through the sample. That is, the gradient filter and the linear array detector obtain the spectral change data of the lubricating oil after aging by performing spectral processing on the wide-spectrum light beam after passing through the sample reflected by the reflection unit, and converting the spectrally processed wide-spectrum light beam after passing through the sample into an electrical signal.

[0058] In this embodiment, the spectral change data of the lubricating oil after aging is accurately obtained by using the gradient filter and the linear array detector in the spectral unit in combination with the wide-spectrum light beam after passing through the sample.

[0059] Further, the spectrum unit is connected to the control transmission unit; the control transmission unit is connected to the display analysis unit, wherein the control transmission unit is connected to the display analysis unit via a wired communication method or a wireless communication method. The control transmission unit controls the measurement spectrum parameters and sampling frequency of the spectrum unit, and sends the location information and temperature information of the monitoring system to the display analysis unit. Further, the spectrum unit sends the spectrum change data of the lubricating oil after aging to the display analysis unit via the control transmission unit.

[0060] Furthermore, the display and analysis unit receives the spectral change data of the lubricant after aging sent by the spectral unit, and calculates and analyzes the viscosity, pH value, nitration value and oxidation value of the lubricant based on the spectral change data of the lubricant after aging. Furthermore, the lubricant aging monitoring system monitors the aging degree of the lubricant based on the viscosity, pH value, nitration value and oxidation value of the lubricant. Furthermore, the lubricant aging monitoring system determines whether it is necessary to replace the lubricant at the location of the measurement system based on the aging degree of the lubricant, and the display and analysis unit also needs to display the aging degree of the lubricant. If it is necessary to replace the lubricant at the location of the measurement system, the display and analysis unit is also required to display an early warning.

[0061] This embodiment calculates and analyzes the viscosity, pH value, nitration value and oxidation value of the lubricating oil, and monitors the aging degree of the lubricating oil through the viscosity, pH value, nitration value and oxidation value of the lubricating oil, thereby being able to accurately monitor the aging degree of the lubricating oil in real time.

[0062] Further, refer to Figure 3 As shown, Figure 3 This is the second structural schematic diagram of the lubricant aging monitoring system provided in the present application. The lubricant aging monitoring system also includes a power supply unit, which controls the transmission unit to supply power to the light source unit, the spectrum unit and the display analysis unit, wherein the power supply method of the light source unit, the spectrum unit and the display analysis unit includes a solar power supply method and / or a mains power supply method.

[0063] It should be further explained that the lubricant aging monitoring system processing provided in the embodiment of the present application can be used for parameter analysis and monitoring of other liquid samples, such as water bodies, in addition to lubricant aging monitoring.

[0064] The lubricant aging monitoring system provided in the present application emits a wide-spectrum light beam through a light source unit and irradiates the wide-spectrum light beam through a sample in a measuring cavity unit to a reflecting unit, and the reflecting unit reflects the wide-spectrum light beam after passing through the sample into a spectral unit for measurement, thereby determining spectral change data caused by lubricant aging, and transmitting the spectral change data to a display analysis unit for calculation and analysis through a control transmission unit, so that the system can monitor the aging degree of the lubricant in real time according to the calculated analysis results of the lubricant.

[0065] Reference Figure 4 , Figure 4 : is a flow chart of the lubricant oil aging monitoring method provided by the present application. The lubricant oil aging monitoring method provided by the present application includes:

[0066] Step S10, controlling the light source unit to emit a broad-spectrum light beam, and irradiating the broad-spectrum light beam into the measuring cavity unit, so that the broad-spectrum light beam passes through the sample in the measuring cavity unit and irradiates the reflecting unit;

[0067] Step S20, reflecting the wide-spectrum light beam after passing through the sample into the spectral unit through the reflection unit, so as to measure the spectral change data of the lubricating oil after aging according to the wide-spectrum light beam after passing through the sample through the spectral unit;

[0068] Step S30, sending the spectrum change data to the display analysis unit through the spectrum unit via the control transmission unit, and calculating and analyzing the viscosity, pH value, nitration value and oxidation value of the lubricating oil according to the spectrum change data through the display analysis unit;

[0069] Step S40, monitoring the aging degree of the lubricating oil according to the viscosity, pH value, nitration value and oxidation value of the lubricating oil.

[0070] After receiving the monitoring control instruction, the lubricating oil aging monitoring system controls the light source unit to emit a broad spectrum light beam. Further, the light source unit irradiates the broad spectrum light beam into the measuring cavity unit connected to the light source unit. Further, the measuring cavity unit has a sample, and therefore, the purpose of the light source unit irradiating the broad spectrum light beam into the measuring cavity unit is to make the broad spectrum light beam pass through the sample in the measuring cavity unit and irradiate on the reflecting unit.

[0071] Furthermore, the lubricant aging monitoring system reflects the wide-spectrum light beam after passing through the sample into the spectral unit through the reflection unit. After the spectral unit receives the wide-spectrum light beam after passing through the sample reflected by the reflection unit, it measures the spectral change data of the lubricant after aging according to the wide-spectrum light beam after passing through the sample. The spectral unit includes a dispersion component and a linear array detector, wherein the dispersion component may include but is not limited to a gradient filter, a grating, a prism and a quantum dot filter. The dispersion component can perform spectroscopic processing on the incident light beam, that is, the gradient filter, the grating, the prism and the quantum dot filter can perform spectroscopic processing on the incident light beam, and the linear array detector can convert the spectroscopically processed incident light beam into an electrical signal. In other words, the structure of the spectral unit can be a combination of a gradient filter and a linear array detector, a combination of a grating and a linear array detector, a combination of a prism and a linear array detector, or a combination of a quantum dot filter and a linear array detector. For ease of understanding, this embodiment takes a combination of a gradient filter and a linear array detector as an example of a spectral unit.

[0072] Furthermore, the reflection unit reflects the wide-spectrum light beam after passing through the sample into the spectrum unit, and the gradient filter and linear array detector in the spectrum unit measure the spectrum change data of the lubricant after aging based on the wide-spectrum light beam after passing through the sample, that is, the gradient filter and the linear array detector perform spectroscopic processing on the wide-spectrum light beam after passing through the sample reflected by the reflection unit, and convert the spectroscopically processed wide-spectrum light beam after passing through the sample into an electrical signal, thereby obtaining the spectrum change data of the lubricant after aging. Furthermore, the lubricant aging monitoring system sends the spectrum change data to the display analysis unit through the spectrum unit via the control transmission unit.

[0073] Furthermore, the display analysis unit receives the spectrum change data of the lubricating oil after aging sent by the spectrum unit, and calculates and analyzes the viscosity, pH value, nitration value and oxidation value of the lubricating oil based on the spectrum change data of the lubricating oil after aging.

[0074] Furthermore, the lubricant aging monitoring system monitors the aging degree of the lubricant according to the viscosity, pH value, nitration value and oxidation value of the lubricant. Finally, the online lubricant aging monitoring determines whether the lubricant at the location of the measurement system needs to be replaced according to the aging degree of the lubricant, and controls the display analysis unit to display the aging degree of the lubricant. If the lubricant at the location of the measurement system needs to be replaced, the display analysis unit needs to be controlled to display an early warning.

[0075] The lubricant aging monitoring method provided in the present embodiment emits a broad-spectrum light beam through a light source unit and irradiates the broad-spectrum light beam through a sample in a measuring cavity unit to a reflecting unit, and the reflecting unit reflects the broad-spectrum light beam after passing through the sample into a spectral unit for measurement, thereby determining spectral change data caused by lubricant aging, and transmitting the spectral change data to a display analysis unit for calculation and analysis through a control transmission unit, so that the system can monitor the aging degree of the lubricant in real time according to the calculated analysis results of the lubricant.
