[0028] like Figure 1 As shown, Figure 1This is a schematic diagram of a system architecture platform for executing a method for detecting vehicle battery indicators and distances, provided in accordance with an embodiment of the present application.

[0029] The system architecture platform 100 of the embodiment of the present application includes one or more processors 110 and a memory 120. Figure 1 In the figure, a processor 110 and a memory 120 are taken as an example.

[0030] The processor 110 and the memory 120 may be connected via a bus or other means. Figure 1 The bus connection is taken as an example.

[0031] The memory 120 is a non-transitory computer-readable storage medium that can be used to store non-transitory software programs and non-transitory computer executable programs. In addition, the memory 120 may include a high-speed random access memory and may also include a non-transitory memory, such as at least one disk storage device, a flash memory device, or other non-transitory solid-state storage device. In some embodiments, the memory 120 may optionally include a memory 120 remotely located relative to the processor 110, and these remote memories may be connected to the system architecture platform 100 via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0032] Those skilled in the art will understand that Figure 1 The device structure shown in the figure does not constitute a limitation on the system architecture platform 100, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0033] exist Figure 1 In the system architecture platform 100 shown, the processor 110 can be used to call the battery indicator and distance detection program stored in the memory 120, thereby implementing the vehicle battery indicator and distance detection method.

[0034] Based on the hardware structure of the above-mentioned system architecture platform 100, various embodiments of the vehicle-mounted optical system of the present application are proposed.

[0035] like Figure 2 As shown, Figure 2 This is a schematic diagram of a vehicle-mounted optical system 200 module for executing a vehicle battery indicator and distance detection method provided by an embodiment of the present application.

[0036] Specifically, the vehicle-mounted optical system 200 of the embodiment of the present application includes a tunable laser light source module 210, a beam splitting module 220, an optical fiber processing module 230, a ranging module 240 and a signal processing module 250. The tunable laser light source module 210 is connected to the beam splitting module 220, the beam splitting module 220 is respectively connected to the ranging module 240 and the optical fiber processing module 230, and the optical fiber processing module 230 and the ranging module 240 are respectively connected to the signal processing module 250.

[0037] It should be noted that the car in the embodiment of the present application may include Figure 1 The processor 110 and memory 120 shown in the figure can communicate with the tunable laser light source module 210, the beam splitting module 220, the optical fiber processing module 230, the ranging module 240 and the signal processing module 250, thereby realizing the vehicle battery indicator and distance detection method.

[0038] Based on the hardware structure of the above-mentioned system architecture platform 100 and the vehicle-mounted optical system 200, various embodiments of the vehicle battery indicator and distance detection method of the present application are proposed.

[0039] like Figure 3 As shown, Figure 3 This is an overall flow chart of a method for detecting vehicle battery indicators and distance provided by an embodiment of the present application. The detection method includes but is not limited to steps S100 to S600.

[0040] Step S100: The tunable laser light source module is linearly modulated, one path is used as a reference light, and the other path is used as a first detection light signal, wherein the first detection light signal is transmitted to the beam splitting module;

[0041] Step S200: The beam splitting module splits the first detection light signal into a second detection light signal and a third detection light signal;

[0042] Step S300: The beam splitting module transmits a second detection light signal to the optical fiber processing module and transmits a third detection light signal to the ranging module;

[0043] Step S400: The optical fiber processing module introduces the second detection light signal into a preset vehicle battery indicator environment and receives a fourth detection light signal reflected by the vehicle battery indicator environment;

[0044] Step S500: The ranging module transmits a third detection light signal to the outside world and receives the third detection light signal reflected by the outside world;

[0045] In step S600, the fourth detection light signal and the third detection light signal are mixed with the reference light to obtain mixed light and enter the signal processing module. The signal processing module converts the mixed light into a beat frequency signal, and then calculates the battery index parameter and the detection distance respectively.

[0046] It is understandable that the wavelength range of the tunable laser light source is 1530 to 1570 nanometers, and the frequency changes linearly with time, one path is the reference light, and the other path is the first detection light.

[0047] It is understandable that the beam splitting module splits the first detection light signal into a second detection light signal and a third detection light signal, with wavelengths ranging from 1530 nanometers to 1570 nanometers. Specifically, the beam splitting module can use a beam splitter. When the first detection light signal is transmitted to the beam splitting module through the laser emitting device, the beam splitter of the beam splitting module splits the first detection light signal into a second detection light signal and a third detection light signal, and then transmits the second detection light signal and the third detection light signal to different modules for processing. The second detection light signal is sent to the optical fiber processing module for optical fiber sensing, and the third detection light signal is sent to the ranging system for detecting the distance of the object. The feature of the shared tunable laser light source in the laser ranging technology and the battery sensing technology is utilized. The beam splitting module is used to divide the linearly modulated detection light into two or more detection light beams for processing. Finally, the detection light is mixed with the reference light to obtain the mixed light to generate a beat frequency signal, thereby combining the laser ranging technology and the battery sensing technology, greatly reducing the cost of the vehicle and reducing the hardware volume of the vehicle-mounted optical system.

[0048] Specifically, the beam splitting module uses a beam splitter to process the first detection light signal, and splits the first detection light signal into a second detection light signal and a third detection light signal through the beam splitter.

[0049] It is understandable that the device or equipment used in the beam splitting module can be selected according to actual conditions and is not specifically limited here.

[0050] like Figure 4 As shown, Figure 4 This is a specific flow chart of step S400 of the vehicle battery indicator and distance detection method provided in an embodiment of the present application. Regarding the optical fiber processing module in step S400, which directs the second detection optical signal to a preset vehicle battery indicator environment and receives the fourth detection optical signal reflected by the vehicle battery indicator environment, the method may include, but is not limited to, steps S411 and S412.

[0051] Step S411: The optical fiber interface imports a second detection optical signal and transmits it to a preset vehicle battery indicator environment through the optical fiber;

[0052] Step S412: The optical fiber Fabry-Perot sensor generates a fourth detection light signal reflected by the vehicle-mounted battery indicator environment.

[0053] It should be noted that the optical fiber processing module includes an optical fiber interface, an optical fiber coupler and a Fabry-Perot sensor. Therefore, the second detection light signal can pass through the optical fiber interface, and then be introduced into the preset vehicle battery environment through the optical fiber coupler and the Fabry-Perot sensor. The fourth detection light signal generated by the vehicle battery environment reflected by the optical fiber Fabry-Perot sensor can pass through the optical fiber coupler again.

[0054] Specifically, the second detection light signal is transmitted into the battery along the optical fiber. Due to the characteristics of the Fabry-Perot sensor, the cavity length of the Fabry-Perot sensor is directly related to the reflected fourth detection light signal.

[0055] It should be noted that the principle of fiber optic detection is as follows: a fiber Fabry-Perot sensor has a hollow Fabry-Perot cavity. When the temperature or stress around the Fabry-Perot sensor changes, the length of the Fabry-Perot cavity changes, causing the signal (intensity, phase, wavelength, etc.) of the probe light reflected by the sensor to change. Furthermore, the beat frequency signal of the mixed light generated by mixing the probe light with the reference light will also change. Due to different time delays, the reflected light from different Fabry-Perot sensors will produce beat frequency signals with different beat frequencies. These beat frequency signals are transmitted to a photodetector, then converted into electrical signals and transmitted to a data acquisition and analysis device. The interference spectrum of each Fabry-Perot sensor can be demodulated using fast Fourier transform (FFT) and inverse fast Fourier transform (IFFT). Therefore, by detecting and analyzing the beat frequency signals, changes in temperature, pressure, and other parameters can be determined. Therefore, when the temperature or pressure inside the battery changes, it will affect the inherent characteristics of the fiber optic Fabry-Perot sensor. For example, thermal expansion and contraction or pressure will cause the length of the Fabry-Perot cavity to change, which will cause the signal of the reflected detection light to change, and further cause the beat frequency signal of the mixed light to change. Then, these beat frequency signals can be analyzed and processed to obtain indicators such as battery temperature and pressure.

[0056] like Figure 5 As shown, Figure 5 This is a specific flow chart of step S500 of the method for detecting vehicle battery indicators and distances provided in an embodiment of the present application. Regarding the aforementioned step S500, the ranging module transmitting the third detection light signal to the outside world and receiving the third detection light signal reflected by the outside world may include, but is not limited to, steps S511 and S512.

[0057] Step S511: The transmitting device transmits a third detection light signal to the outside world;

[0058] Step S512: The laser receiving device receives the third detection light signal reflected by the outside world;

[0059] Specifically, the ranging module includes a transmitting device and a laser receiving device. Therefore, when the ranging module receives the third detection light signal emitted by the beam splitting module, the transmitting device transmits the third detection light signal to the outside world. When the third detection light signal encounters an external object, it is reflected back, so that the laser receiving device can receive the third detection light signal reflected back by the object.

[0060] like Figure 6 As shown, Figure 6 This is a detailed flowchart of step S600 of the method for detecting vehicle battery indicators and distances provided in an embodiment of the present application. In step S600, the fourth and third detection light signals are mixed with the reference light to generate a mixed light, which enters the signal processing module. The signal processing module converts the mixed light into a beat frequency signal, including but not limited to steps S611 and S612.

[0061] Step S611: The fourth detection light signal and the third detection light signal are mixed with the reference light to obtain mixed light;

[0062] Step S612: The signal processing module converts the mixed light into a beat frequency signal.

[0063] Specifically, the signal processing module includes a photodetector and a data acquisition and analysis device. The fourth detection light signal and the third detection light signal are mixed with the reference light. The mixed light enters the photodetector, converts the light signal into an electrical signal, and transmits the beat frequency signal to the data acquisition and analysis device.

[0064] It should be noted that when the temperature or pressure inside the battery changes, the intensity of the reflected fourth detection light signal changes, thereby causing the beat frequency signal of the mixed light to also change.
