Description

Technical Field

[0001] The present invention relates to the technical field of photoelectric accelerometer driving, and in particular to a photoelectric accelerometer driving method and system based on multi-physical signal fusion. Background Art

[0002] A photoelectric accelerometer is a device that uses the principle of the photoelectric effect to measure acceleration. It is mainly used in aerospace, automotive, construction and other fields to monitor the motion state and dynamic behavior of objects. The working principle usually involves the use of lasers, optical fibers or photoelectric sensors. By measuring changes in light such as light intensity, wavelength or frequency, the photoelectric accelerometer can detect changes in the acceleration of an object and convert it into an electrical signal for subsequent analysis and processing.

[0003] A laser accelerometer with patent publication number CN108646053A. When the laser accelerometer has acceleration, the elastic part undergoes elastic deformation due to the inertial force, thereby driving a high-reflection part to approach or move away from the emission end of a corresponding microcrystalline glass laser, and the other high-reflection part moves away from or close to the emission end of another corresponding microcrystalline glass laser, so that each microcrystalline glass laser generates a laser with a frequency difference. The frequency difference can be measured by a photoelectric detector, and then the acceleration value is obtained. By using a conventional laser and an acceleration sensing element with a simple structure, the measurement of acceleration is achieved while making the manufacturing simple and low-cost.

[0004] When driving photoelectric accelerometers, the above-mentioned and similar technical solutions usually use light-emitting diodes to emit light that is received by photosensitive diodes, and most light-emitting diodes will choose near-infrared light, especially near-infrared light with a wavelength of about 850nm, because it exhibits good stability in a wide range of humidity and temperature. However, under certain extreme environmental conditions, near-infrared light cannot maintain stable transmission characteristics, which may affect the performance of near-infrared light, such as peak wavelength drift, which in turn affects the detection results of the accelerometer.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the application of photoelectric accelerometers, the near-infrared light emitted by light-emitting diodes has a narrow emission spectrum width, which is easy to match with the receiving spectrum width of photosensitive diodes, so it can effectively improve the contrast of signals. In addition, near-infrared light near 850nm can attenuate less in the atmosphere, so that reliable measurement results can be obtained under various environmental conditions. However, this advantage is not absolute. Under certain extreme operating conditions, the stability of near-infrared light faces severe tests. Under extreme temperature conditions, the peak wavelength of near-infrared light may drift, thereby affecting the photoelectric conversion efficiency of the photoelectric accelerometer. Under high temperature conditions, the luminous efficiency of light-emitting diodes may decrease, and even luminous attenuation may occur. At the same time, when receiving signals, photosensitive diodes may also be affected by temperature changes, resulting in reduced sensitivity. This situation will directly affect the strength of the signal and its ratio to noise, further damaging the accelerometer. The data collection accuracy of the meter, the change of humidity will also affect the near-infrared light transmission characteristics of the photoelectric accelerometer. In a high humidity environment, the presence of water vapor will cause light scattering and absorption, affecting the integrity of the signal. The technical solution provided by the present application sets a multi-light source array component and a multi-light source receiving component. The multi-light source array component is composed of near-infrared light, mid-infrared light, and red light. Under different conditions, it automatically selects appropriate light so that the multi-light source receiving component can always receive a stable light source signal, and by setting a critical state, the critical state includes a fluctuation limit value and a time threshold, to determine whether the multi-light source array component and the multi-light source receiving component have reached a critical state. When the fluctuation limit value is reached within the time threshold, the light of the multi-light source array component is adjusted by a matching method, thereby realizing the matching adjustment of the light and improving the receiving stability of the multi-light source receiving component. Specifically in the present application, Figure 1 As shown, steps S100-S500 are included.

[0020] Step S100: setting a multi-light source array component and a multi-light source receiving component, wherein the multi-light source receiving component sets a corresponding spectrum range based on the multi-light source array component to obtain a target range item.

[0021] It should be noted that if Figure 2As shown, the multi-light source array component includes near-infrared light, mid-infrared light and red light, and the method for obtaining the target range item includes: based on the multi-light source array component, setting the near-infrared light, mid-infrared light and red light as the first light source, the second light source and the third light source respectively; obtaining the band data of the first light source, the second light source and the third light source to obtain the band information item; based on the band information item, setting the coverage range, the coverage range includes the band information item, and obtaining the target range item.

[0022] In the specific implementation process, since the first light source, the second light source and the third light source are near-infrared light, mid-infrared light and red light respectively, the band data of the three are obtained respectively, among which the band data of near-infrared light is 850nm, the band data of mid-infrared light is 3000nm-5000nm, and the band data of red light is 630nm-660nm. At this time, the coverage range is set to 630nm-5000nm, which includes the band information item.

[0023] Step S200: Acquire ambient temperature and humidity data, set a target temperature range and a target humidity range, and obtain a target temperature item and a target humidity item.

[0024] It should be noted that the method for obtaining the target temperature item and the target humidity item includes: obtaining the ambient temperature and humidity data respectively through the target device, the target device is a temperature sensor and a humidity sensor, to obtain the ambient temperature item and the ambient humidity item; based on a multi-light source array component, taking the first light source as the target light source, to obtain the target light source item; based on the target light source item, obtaining the temperature and humidity adaptation range of the target light source item, and then obtaining the target temperature item and the target humidity item.

[0025] Specifically, since the first light source is near-infrared light, the target light source item is near-infrared light, and the temperature and humidity adaptation range of the near-infrared light is obtained. Since the band data of near-infrared light is 850nm, it is relatively insensitive to changes in humidity and temperature. Under most industrial and environmental conditions, such as temperature between -20℃ and 60℃ and humidity between 10% and 90%, near-infrared light can maintain stable transmission characteristics. Therefore, the target temperature item is -20℃-60℃, and the target humidity item is 10%-90%.

[0026] Step S300: Determine whether the ambient temperature and humidity are within the target temperature and humidity ranges.

[0027] It should be noted that when the ambient temperature and humidity are at the target temperature item and the target humidity item, based on the multi-light source array component, the first target light is selected as the basic light, and the basic light is used as the first light. The multi-light source receiving component obtains the first light data to obtain the first light item. The first target light is the first light source, that is, near-infrared light. At this time, the first light data obtained by the multi-light source receiving component is near-infrared light. When the ambient temperature and humidity are not at the target temperature item and the target humidity item, the second target light is selected as the second light through the processing method, and the multi-light source receiving component obtains the second light data to obtain the second light item.

[0028] It should be noted that if Figure 4 As shown, the processing method includes: based on the target temperature item and the target humidity item, respectively setting the first interval and the second interval, the first interval is that the temperature and humidity are less than the target temperature item and the target humidity item, and the second interval is that the temperature and humidity are greater than the target temperature item and the target humidity item. When the target temperature item and the target humidity item are -20℃-60℃ and 10%-90% respectively, the first interval is that the temperature is less than -20℃ and the humidity is less than 10%, and the second interval is that the temperature is greater than 60℃ and the humidity is greater than 90%; based on the multi-light source array component, respectively matching the first interval and the second interval to obtain the first interval light item and the second interval light item, the first interval light item is red light, and the second interval light item is mid-infrared light; judging the real-time interval segmentation of the ambient temperature and humidity, obtaining the target interval item, and then obtaining the target demand light, and obtaining the second target light.

[0029] In the specific implementation process, Figure 5 As shown, the temperature and humidity data obtained by the temperature sensor and the humidity sensor are -22°C and 5% respectively. At this time, it is allocated to the first interval, and the light item in the first interval is red light, that is, the second target light is red light.

[0030] Step S400: Optimizing the second light item through a succession method so that the second light item succeeds the first light item, completing the switching of the target light, and ensuring that the light received by the multi-light source receiving component always remains stable.

[0031] It should be noted that the succession method includes: setting an acquisition threshold, the acquisition threshold is time, and the acquisition threshold is 10s, judging whether the duration of the second light item reaches the time threshold, when the duration of the second light item reaches the time threshold, turning off the first light, so that the second light item replaces the first light item.

[0032] Embodiment 1

[0033] In the specific implementation process, it is necessary to obtain the rotation speed of an object by pasting a reflective sticker on the object. When the temperature is 25°C and the humidity is 50%, the first light item selected by the multi-light source array component is near-infrared light. When the object rotates one circle, the multi-light source receiving component receives the near-infrared light emitted by the multi-light source array component reflected by the reflective sticker. When the humidity of the detection environment decreases from 50% to 8%, the target interval item is the first interval, and the light corresponding to the first interval is red light, so the second target light is red light. At this time, the multi-light source array component emits red light and near-infrared light at the same time. Through the set acquisition threshold, since the acquisition threshold is 10s, when the duration of the second target light, that is, the red light, reaches the acquisition threshold, the first light, that is, the near-infrared light, is extinguished, and the red light replaces the near-infrared light to continue detection.

[0034] It should be noted that if Figure 3 As shown, the succession method also includes: acquiring the pulse frequency of the first light item and the second light item to obtain the first pulse item and the second pulse item; setting an acquisition range, the acquisition range is a time range, and the time range is 10s, based on the acquisition range, acquiring the duration information of the first pulse item and the second pulse item to obtain the first change item and the second change item; judging the fluctuation data of the first change item and the second change item, when the fluctuation data of the first change item is less than the fluctuation data of the second change item, turning off the first light, so that the second light item replaces the first light item.

[0035] Embodiment 2

[0036] In the specific implementation process, Figure 6 As shown, a multi-light source array component, a sunshade 1 and a multi-light source receiving component are installed on the wheel of a certain vehicle. The sunshade 1 rotates with the rotation of the wheel and keeps synchronization with the rotation of the wheel. There are 19 evenly distributed sunshade strips 101 on the sunshade 1. When the sunshade 1 cannot block the light emitted by the multi-light source array component, the multi-light source receiving component will receive the light emitted by the multi-light source array component. When the temperature is 25°C and the humidity is 50%, the first light item selected by the multi-light source array component is near-infrared light. When the sunshade 1 rotates one circle, the multi-light source array component The light source receiving component will receive 20 pulse signals of the first light item. When the temperature changes to -25℃ and the humidity is 5%, the second light item is red. According to the set time range, within 10s, the multi-light source receiving component receives the pulse signal of the first light item 1999 times, that is, the first change item is 1999, and receives the pulse signal of the second light item 2000 times, that is, the second change item is 2000. At this time, the fluctuation data of the first change item is smaller than the fluctuation data of the second change item, even if the second light item replaces the first light item.

[0037] Step S500: setting a critical state, judging the multi-light source array component and the multi-light source receiving component through a judgment method, adjusting the light of the multi-light source array component, realizing matching adjustment of the light, and improving the receiving stability of the multi-light source receiving component.

[0038] It should be noted that the critical state includes the fluctuation limit value and the time threshold. The time threshold is 300s, and the fluctuation limit value is 50 of the difference between the target temperature item and the target humidity item, that is, the temperature fluctuation limit value is 40°C, and the humidity fluctuation limit value is 40%. The judgment method includes: based on the time threshold, judging whether the changes in ambient temperature and humidity reach the fluctuation limit value. When the changes in ambient temperature and humidity reach the fluctuation limit value within the time threshold, taking the change direction as the target direction, and obtaining the target change item.

[0039] During the specific implementation process, the multi-light source array assembly, the sunshade 1 and the multi-light source receiving assembly installed on the wheel of a vehicle obtained a temperature of 35°C and a humidity of 10%. Within the time threshold, the humidity data changed to 70%. At this time, the humidity change exceeded the humidity fluctuation limit value set by 40%, and the change direction was upward.

[0040] It should be noted that the lighting adjustment method of the multi-light source array component includes: based on the combination results of the target change item with the target temperature item and the target humidity item, at least four combination results are obtained, namely, the target change item is downward and lower than the target temperature item and the target humidity item, between the target temperature item and the target humidity item and the target change item is downward, between the target temperature item and the target humidity item and the target change item is upward, the target change item is upward, and higher than the target temperature item and the target humidity item, to obtain a combination result item; based on the combination result item and the multi-light source array component, the first light source, the second light source and the third light source are adjusted as an adjustment combination, and the combination results are respectively: the target change item is downward and lower than the target temperature item and the target humidity item, combined with the third light source, between the target temperature item and the target humidity item and the target change item is downward, combined with the first light source and the third light source, between the target temperature item and the target humidity item and the target change item is upward, combined with the first light source and the second light source, the target change item is upward and higher than the target temperature item and the target humidity item, and combined with the first light source and the second light source.

[0041] Embodiment 3

[0042] In the specific implementation process, the multi-light source array component, the sunshade 1 and the multi-light source receiving component installed on the wheel of a vehicle, within the time threshold, the humidity data changes from 10% to 70%, and the humidity change exceeds the humidity fluctuation limit value set by 40%. At this time, the change direction is upward, and then because the 70% humidity data does not exceed the target humidity item, the combination result of the target change item, the target temperature item and the target humidity item is: between the target change item, the target temperature item and the target humidity item and the target change item is upward, and the matching result is the first light source and the second light source.
