Description

Technical Field

[0001] Embodiments of the present invention relate to the field of motor vehicle exhaust gas monitoring, and in particular, to an optical energy display device and a motor vehicle exhaust remote sensing monitoring device. Background Art

[0002] As one of the important means of transportation in modern society, motor vehicles bring great convenience to people's work and life. However, the exhaust gas emitted by motor vehicles has also become an important source of air pollution and an important cause of haze and photochemical smog pollution. The above shows that motor vehicle exhaust gas monitoring is particularly important.

[0003] At present, motor vehicle exhaust remote sensing monitoring devices usually detect motor vehicle exhaust based on the principle of optical energy characteristic absorption. Before the motor vehicle exhaust remote sensing monitoring device monitors the motor vehicle exhaust, the optical path in the motor vehicle exhaust remote sensing monitoring device needs to be aligned and detected to ensure that the motor vehicle exhaust remote sensing monitoring device is in a normal working state. Among them, the alignment and detection results can be displayed through the optical energy display module in the optical energy display device. In the prior art, the following two optical energy display modules are usually used to display the alignment and detection results. Specifically: First, an off-board digital tube is used for display. That is, the optical energy display module includes at least one digital tube, and each digital tube is used to display the optical energy signal of a light source; Second, an on-board digital tube is used for display. That is, the optical energy display module includes at least one digital tube, and each digital tube is used to display the optical energy signal of a light source. The magnitude of the above optical energy signal will be reflected by the value displayed on the digital tube.

[0004] However, it is found that there are at least the following problems in the prior art: Since each light source corresponds to a digital display tube, the integration degree of the optical energy display device is not high. In addition, in an environment with a large single-path optical path, due to the small size of the digital tube, the value displayed on the digital tube cannot be clearly seen from a long distance, that is, the recognition degree at a long distance is not high, which further increases the difficulty of aligning and detecting the optical path in the motor vehicle exhaust remote sensing monitoring device.

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. The various features recorded in the embodiments can be combined to form multiple alternative solutions. Additionally, it should be noted that for the sake of convenience of description, only parts related to the present invention rather than all structures are shown in the drawings.

[0050] Figure 1 It is a schematic structural diagram of a light energy display device provided in an embodiment of the present invention, and this embodiment is applicable to the situation of improving the integration degree and long-distance recognition degree of the light energy display device. As Figure 1 shown, the light energy display device 1 may specifically include a light source emission module 10, a light source reception module 11, a processing module 12, and a multi-channel light energy display module 13. The structures and functions thereof will be described below.

[0051] The multi-channel light energy display module 13 may specifically include at least one LED (Light Emitting Diode) light column 130. The processing module 12 may be communicatively connected to the light source reception module 11 and the multi-channel light energy display module 13 respectively.

[0052] The light source emission module 10 may be used to emit an original light source signal.

[0053] The light source reception module 11 may be used to receive the original light source signal, convert the original light source signal into a target electrical signal, and send the target electrical signal to the processing module 12.

[0054] The processing module 12 may be used to process the target electrical signal to obtain a target light energy signal, and send the target light energy signal to the multi-channel light energy display module 13.

[0055] The multi-channel light energy display module 13 can be used to display the target light energy signal, and the LED light columns correspond one-to-one with the target light energy signal.

[0056] In an embodiment of the present invention, in order to improve the integration and long-distance recognition of the light energy display device, the multi-channel light energy display module 13 can be set to include at least one LED light column 130 to solve the problem. Specifically, the light energy display device 1 can specifically include a light source emission module 10, a light source reception module 11, a processing module 12, and a multi-channel light energy display module 13. Among them, the light source emission module 10 can specifically include at least one light source emission unit, and the light source reception module 11 can specifically include at least one light source reception unit. The light source emission unit and the light source reception unit can correspond one-to-one. That is, if the number of light source emission units is M, M≥1, then the number of light source reception units is also M. The processing module 12 can include at least one processing unit. The multi-channel light energy display module 13 can include at least one LED light column 130. The processing module 12 can be communicatively connected to the light source reception module 11, and the processing module 12 can also be communicatively connected to the multi-channel light energy display module 13.

[0057] The light source emission module 10 can emit an original light source signal, which can be understood as follows: The light source emission module 10 can emit an original light source signal. It should be noted that since the light source emission module 10 can include at least one light source emission unit, and each light source emission unit can emit an original light source signal, the number of original light source signals can be at least one. That is, if the light source emission module 10 can include M light source emission units, M≥1, then the number of original light source signals is M. Exemplarily, if the light source emission module 10 can include a first light source emission unit, a second light source emission unit, and a third light source emission unit, the first light source emission unit, the second light source emission unit, and the third light source emission unit can respectively emit corresponding original light source signals, and the number of original light source signals is three.

[0058] The light source receiving module 11 can receive the original light source signal, convert the original light source signal into a target electrical signal, and send the target electrical signal to the processing module 12. It can be understood as follows: The light source receiving module 11 can receive the original light source signal emitted by the light source emitting module 10, convert the original light source signal into a target electrical signal, and send the target electrical signal to the processing module 12. It should be noted that since the light source receiving module 11 can include at least one light source receiving unit, and each light source receiving unit can receive one type of original light source signal, therefore, the number of target electrical signals can be at least one. At the same time, the number of target electrical signals is equal to the number of original light source signals and the target electrical signals and the original light source signals are in one-to-one correspondence. In addition, since the light source receiving unit and the light source emitting unit are in one-to-one correspondence, each light source receiving unit can be used to receive the original light source signal emitted by the light source emitting unit corresponding to this light source receiving unit and convert the original light source signal into a target electrical signal. The light source receiving unit can be a photodetector.

[0059] The processing module 12 can process the target electrical signal to obtain a target light energy signal, and send the target light energy signal to the multi-channel light energy display module 13. It can be understood as follows: The processing module 12 can receive the target electrical signal sent by the light source receiving module 11, process the target electrical signal to obtain a target light energy signal, and send the target light energy signal to the multi-channel light energy display module 13, so that the multi-channel light energy display module 13 can display the target light energy signal. The target light energy signal can be used to represent the magnitude of the light energy value of the original light source signal emitted by each light source emitting unit in the light source emitting module 10. The target light energy signal and the target electrical signal are in one-to-one correspondence. Since the target electrical signal and the original light source signal are in one-to-one correspondence, therefore, the target light energy signal and the original light source signal are in one-to-one correspondence. Based on this, the target light energy signal, the target electrical signal, and the original light source signal are all in one-to-one correspondence. It can be understood that since the original light source signal is emitted by each light source emitting unit in the light source emitting module 10, the number of light source emitting units will determine the number of target light energy signals. That is, if the number of light source emitting units is M, then the number of target light energy signals is also M.

[0060] The multi-channel light energy display module 13 can display the target light energy signal, and the LED light columns are in one-to-one correspondence with the target light energy signal. It can be understood as follows: The multi-channel light energy display module 13 can receive the target light energy signal sent by the processing module 12 and display the target light energy signal. The multi-channel light energy display module 13 can include at least one LED light column 130, and each LED light column 130 is used to display the target light energy signal corresponding to this LED light column 130, that is, the LED light column 130 is in one-to-one correspondence with the target light energy signal. As Figure 2 shown, a structural schematic diagram of a multi-channel light energy display module is given.Figure 2 The multi-channel light energy display module 13 shown may include at least one LED light column 130. As can be known from the above, the number of target light energy signals is determined by the number of light source emission units. The LED light column 130 belongs to the LED light column of the separated scattering process. At least one LED light column 130 can form an LED light column display. Correspondingly, the multi-channel display module 13 can include at least one LED light column 130, which can be understood as that the multi-channel display module 13 can be an LED light column display. Optionally, the LED light column display can be an LED light column display composed of 10 27-mm LED light columns 130. Among them, 10 can represent the number of LED light columns 130, and 27 mm can represent that the center distance between the first LED light column 130 and the last LED light column 130 among the 10 LED light columns 130 is 26.6 mm. Based on this, it can be understood that the number of LED light columns 130 can be greater than or equal to the number of light source emission units, so that each LED light column 130 can be used to display the target light energy signal corresponding to the LED light column 130. The alignment detection result of the optical path formed by the light source corresponding to the LED light column 130 in the motor vehicle exhaust remote sensing monitoring device can be determined according to whether the LED light column 130 displays the target light energy signal, and then the working state of the motor vehicle exhaust remote sensing monitoring device can be determined according to the alignment detection result. If the LED light column 130 can display the target light energy signal, it can be explained that the optical path formed by the light source corresponding to the LED light column 130 in the motor vehicle exhaust remote sensing monitoring device has been adjusted, that is, the alignment detection result is that the optical path is normal, and then it can be explained that the motor vehicle exhaust remote sensing monitoring device is in a normal working state. If the LED light column 130 does not display the target light energy signal, it can be explained that the optical path formed by the light source corresponding to the LED light column 130 in the motor vehicle exhaust remote sensing monitoring device has not been adjusted, that is, the alignment detection result is that the optical path is abnormal, and then it can be explained that the motor vehicle exhaust remote sensing monitoring device is in an abnormal working state. It should be noted that the magnitude of the light energy value required for the LED light column 130 to display the target light energy signal is not limited and can be set according to the actual situation. Optionally, in order to further improve the accuracy of the alignment detection result of the optical path in the motor vehicle exhaust remote sensing monitoring device, it can be considered that if the light energy value of the target light energy signal is greater than or equal to the light energy threshold, then the target light energy signal can be displayed through the LED light column 130. Correspondingly, if the light energy value of the target light energy signal is less than the light energy threshold, then the target light energy signal cannot be displayed through the LED light column 130. In addition, a light energy threshold corresponding to each target light energy signal can be set. The light energy thresholds of different target light energy signals can be equal or unequal, and can be specifically set according to the actual situation, and no specific limitation is made here.

[0061] By setting up the multi-channel light energy display module 13 including at least one LED light column 130 as described above, it is possible to simultaneously and centrally display the target light energy signals of the light sources used in the motor vehicle exhaust remote sensing monitoring equipment, improving the integration of the light energy display device. Moreover, since the LED light column 130 is made of a high-brightness digital tube and a special light guide material, using the LED light column 130 to display the target light energy signal can improve the long-distance recognition of the light energy display device 1. Since the long-distance recognition of the light energy display device 1 is improved, the difficulty of optical alignment detection for the optical path in the motor vehicle exhaust remote sensing monitoring equipment is reduced.

[0062] In addition, since the multi-channel light energy display module 13 has independent on-board heat dissipation and does not require additional heat dissipation, the service life of the light source can be effectively increased. The service life of the light source of the light energy display device 1 provided by the embodiment of the present invention can be increased by 40% compared with that in the traditional technology. Since the light energy display device 1 provided by the embodiment of the present invention adopts an on-board structure, the volume is smaller, which is conducive to the miniaturization design of the motor vehicle exhaust remote sensing monitoring equipment.

[0063] In the technical solution of this embodiment, by setting up the light energy display device 1 including a light source emission module 10, a light source reception module 11, a processing module 12, and a multi-channel light energy display module 13, the multi-channel light energy display module 13 includes at least one LED light column 130. The light source emission module 10 is used to emit the original light source signal, the light source reception module 11 is used to receive the original light source signal, convert the original light source signal into a target electrical signal, and send the target electrical signal to the processing module 12. The processing module 12 is used to process the target electrical signal to obtain the target light energy signal, and send the target light energy signal to the multi-channel light energy display module 13. The multi-channel light energy display module 13 is used to display the target light energy signal, and the LED light column 130 corresponds one-to-one with the target light energy signal. By setting up the multi-channel light energy display module including at least one LED light column as described above, it is possible to simultaneously and centrally display the target light energy signals of the light sources used in the motor vehicle exhaust remote sensing monitoring equipment, improving the integration of the light energy display device 1. Moreover, since the LED light column 130 is made of a high-brightness digital tube and a special light guide material, using the LED light column 130 to display the target light energy signal improves the long-distance recognition of the light energy display device 1, and further reduces the difficulty of optical alignment detection for the optical path in the motor vehicle exhaust remote sensing monitoring equipment.

[0064] Optionally, as Figure 3 shown, on the basis of the above technical solution, the light energy display device 1 may specifically further include a first light energy adjustment module 14. The first light energy adjustment module 14 can be communicatively connected to the multi-channel light energy display module 13.

[0065] The first light energy adjustment module 14 can be used to receive a first ambient light brightness signal input by a user according to the ambient light brightness of the environment where the light energy display device 1 is located, and can adjust the brightness when the multi-channel light energy display module 13 displays a target light energy signal according to the first ambient light brightness signal.

[0066] In an embodiment of the present invention, at a long distance, in order to enable the light energy display device 1 to achieve a high recognition effect under different ambient light conditions, that is, to enable the light energy display device 1 to adapt to all-weather ambient light conditions and achieve a high recognition effect. The so-called all-weather ambient light conditions can be understood to include strong light conditions during the day and weak light conditions at night. It can be considered to be achieved by adjusting the brightness of the multi-channel light energy display module 13. Specifically:

[0067] As Figure 3 shown, a schematic structural diagram of another light energy display device is given. Figure 3 A first light energy adjustment module 14 can be provided on the light energy display device 1. The first light energy adjustment module 14 can be communicatively connected to the multi-channel light energy display module 13. The first light energy adjustment module 14 can receive a first ambient light brightness signal input by a user according to the ambient light brightness of the environment where the light energy display device 1 is located, and can adjust the brightness when the multi-channel light energy display module 13 displays a target light energy signal according to the first ambient light brightness signal. The above shows that the first ambient light brightness signal can be determined by the user according to the ambient light brightness of the environment where the light energy display device 1 is located. A corresponding first ambient light brightness signal can be set for each LED light column 130. Correspondingly, the number of first ambient light brightness signals can be at least one. The first ambient light brightness signals of different LED light columns 130 can be the same or different, and can be specifically set according to actual situations, and no specific limitation is made here.

[0068] The above adjusts the brightness when the light energy display module 13 displays a target light energy signal according to the first ambient light brightness signal determined by the user according to the ambient light brightness of the environment where the light energy display device 1 is located, so that at a long distance, the light energy display device 1 can achieve a high recognition effect under different ambient light conditions, that is, the light energy display device 1 can adapt to all-weather ambient light conditions and achieve a high recognition effect. In short, the effects of high recognition at a long distance and adaptation to all-weather ambient light conditions are achieved.

[0069] Optionally, as Figure 4As shown, on the basis of the above technical solution, the light energy display device 1 may specifically further include an ambient light sensor 15 and a second light energy adjustment module 16. The ambient light sensor 15 may be communicatively connected to the processing module 12, and the second light energy adjustment module 16 may be communicatively connected to the processing module 12 and the multi-channel light energy display module 13 respectively.

[0070] The processing module 12 may further be configured to control the ambient light sensor 15 to collect a second ambient light brightness signal of the environment where the light energy display device 1 is located, and send the received second ambient light brightness signal to the second light energy adjustment module 16.

[0071] The second light energy adjustment module 16 may be configured to adjust the brightness when the multi-channel light energy display module 13 displays the target light energy signal according to the second ambient light brightness signal.

[0072] In an embodiment of the present invention, at a long distance, in order to enable the light energy display device 1 to achieve a high recognition effect under different ambient light conditions, that is, to enable the light energy display device 1 to adapt to all-weather ambient light conditions and achieve a high recognition effect. The so-called all-weather ambient light conditions can be understood to include strong light conditions during the day and weak light conditions at night. It can be considered to be achieved by adjusting the brightness of the multi-channel light energy display module 13. Specifically:

[0073] As Figure 4 shown, a structural schematic diagram of another light energy display device is given. Figure 4 An ambient light sensor 15 and a second light energy adjustment module 16 may be provided on the light energy display device 1. The ambient light sensor 15 may be communicatively connected to the processing module 12, and the second light energy adjustment module 16 may be communicatively connected to the processing module 12 and the multi-channel light energy display module 13 respectively. The processing module 12 may receive the second ambient light brightness of the environment where the light energy display device 1 is located collected by the ambient light sensor 15, and may send the received second ambient light brightness to the second light energy adjustment module 16, so that the second light energy adjustment module 16 can adjust the brightness when the multi-channel light energy display module 13 displays the target light energy signal according to the second ambient light brightness. The above shows that the second ambient light brightness signal can be determined by the ambient light sensor 15 collecting the ambient light brightness of the environment where the light energy display device 1 is located. A corresponding second ambient light brightness signal may be set for each LED light column 130. Correspondingly, the number of second ambient light brightness signals may be at least one. The second ambient light brightness signals of different LED light columns 130 may be the same or different, and may be specifically set according to actual situations, and no specific limitation is made here.

[0074] It should be noted that the ambient light sensor 15 can also be communicatively connected to the second light energy adjustment module 16. Correspondingly, the second ambient light luminance signal collected by the ambient light sensor 15 can be directly sent to the second light energy adjustment module 16, so that the second light energy adjustment module 16 can adjust the luminance when the multi-channel light energy display module 13 displays the target light energy signal according to the second ambient light luminance signal.

[0075] It should also be noted that the first light energy adjustment module 14, the ambient light sensor 15, and the second light energy adjustment module 16 can be simultaneously provided on the light energy display device 1. Specifically: the first light energy adjustment module 14 can be communicatively connected to the multi-channel light energy display module 13, the ambient light sensor 15 can be communicatively connected to the processing module 12, and the second light energy adjustment module 16 can be communicatively connected to the processing module 12 and the multi-channel light energy display module 13 respectively. On this basis, the first light energy adjustment module 14 can receive the first ambient light luminance signal input by the user according to the ambient light luminance of the environment where the light energy display device 1 is located, and can adjust the luminance when the multi-channel light energy display module 13 displays the target light energy signal according to the first ambient light luminance signal. Alternatively, the processing module 12 can control the ambient light sensor 15 to collect the second ambient light luminance signal of the environment where the light energy display device 1 is located, and send the received second ambient light luminance signal to the second light energy adjustment module 16. The second light energy adjustment module 16 can adjust the luminance when the multi-channel light energy display module 13 displays the target light energy signal according to the second ambient light luminance signal. Alternatively, the first light energy adjustment module 14 can receive the first ambient light luminance signal input by the user according to the ambient light luminance of the environment where the light energy display device is located.

Alternatively, the processing module 12 can control the ambient light sensor 15 to collect a second ambient light brightness signal of the environment where the light energy display device 1 is located, and can control the light sensor 15 to send the second ambient light brightness signal to the second light energy adjustment module 16. The second light energy adjustment module 16 can adjust the brightness when the multi-channel light energy display module 13 displays the target light energy signal according to the second ambient light brightness signal. Alternatively, the first light energy adjustment module 14 can receive a first ambient light brightness signal input by the user according to the ambient light brightness of the environment where the light energy display device 1 is located. The processing module 12 can control the ambient light sensor 15 to collect a second ambient light brightness signal of the environment where the light energy display device 1 is located, and can control the light sensor 15 to send the second ambient light brightness signal to the second light energy adjustment module 16.

[0077] It should be further noted that the above-mentioned first light energy adjustment module 14 and second light energy adjustment module 16 can be the same light energy adjustment module or different light energy adjustment modules, which can be specifically set according to the actual situation and are not specifically limited here. If the first light energy adjustment module 14 and the second light energy adjustment module 16 are the same light energy adjustment module, the light energy display device 1 can be provided with an ambient light sensor 15 and a light energy adjustment module.

The original light source signal may include a first original light source signal and a second original light source signal. Correspondingly, the target electrical signal corresponding to the first original light source signal may be a first target electrical signal, and the corresponding target optical energy signal may be a first target optical energy signal. The target electrical signal corresponding to the second original light source signal may be a second target electrical signal, and the corresponding target optical energy signal may be a second target optical energy signal.

[0095] In an embodiment of the present invention, as Figure 6 shown, a structural schematic diagram of another light energy display device is given. Figure 6Among them, the processing module 12 may specifically include a third processing unit 122 and a fourth processing unit 123. The multi-channel optical energy display module 13 may be communicatively connected to the third processing unit 122 and the fourth processing unit 123 respectively. The original light source signal may include a third original light source signal and a fourth original light source signal. Correspondingly, the target electrical signal corresponding to the third original light source signal may be a third target electrical signal, and the corresponding target optical energy signal may be a third target optical energy signal. The target electrical signal corresponding to the fourth original light source signal may be a fourth target electrical signal, and the corresponding target optical energy signal may be a fourth target optical energy signal. Understood from another perspective, the target electrical signal may include a third target electrical signal and a fourth target electrical signal. The target optical energy signal may include a third target optical energy signal and a fourth target optical energy signal. It should be noted that the number of the third original light source signals may be at least P, where P≥1. According to the above description, it can be known that the third original light source signal, the third target electrical signal, and the third target optical energy signal are in one-to-one correspondence. Based on this, the number of the third original light source signals, the number of the third target electrical signals, and the number of the third target optical energy signals are equal, that is, the number of the third target electrical signals may also be at least P, and the number of the third target optical energy signals may also be at least P.

According to the above description, it can be known that the fourth original light source signal, the fourth target electrical signal, and the fourth target optical energy signal are in one-to-one correspondence. Based on this, the number of the fourth original light source signals, the number of the fourth target electrical signals, and the number of the fourth target optical energy signals are equal, that is, the number of the fourth target electrical signals may also be at least Q, and the number of the fourth target optical energy signals may also be at least Q.

[0096] The light source receiving module 11 may receive the original light source signal, convert the original light source signal into a target electrical signal, and may send the target electrical signal to the processing module 12. It can be understood as follows: The light source receiving module 11 may receive the third light source signal and the fourth original light source signal, convert the first original light source signal into the first target electrical signal, convert the second original light source signal into the second target electrical signal, and may send the first target electrical signal to the first processing unit 120 and send the second target electrical signal to the second processing unit 121. That is, the first processing unit 120 and the second processing unit 121 may process the target electrical signals corresponding to them respectively.

[0097] The processing module 12 can process the target electrical signal to obtain a target optical energy signal, and can send the target optical energy signal to the multi-channel optical energy display module 13. It can be understood as follows: The third processing unit 122 can process the third target electrical signal to obtain a third target optical energy signal, and can send the third target optical energy signal to the multi-channel optical energy display module 13. The fourth processing unit 123 can process the fourth target electrical signal to obtain a fourth target optical energy signal, and can send the fourth target optical energy signal to the multi-channel optical energy display module 13. Among them, the third target optical energy signal and the fourth target optical energy signal can be used as the target optical energy signal. That is, the target optical energy signal can include the third target optical energy signal and the fourth target optical energy signal.

[0098] It can be understood that for the third target electrical signal and the fourth target electrical signal, it can also be understood as follows: The target electrical signal processed by the third processing unit 122 can be called the third target electrical signal. The target power signal processed by the fourth processing unit 123 can be called the fourth target electrical signal. On this basis, since the third target electrical signal is converted from the third original light source signal by the corresponding light source receiving unit in the light source receiving module 11, and the third original light source signal is emitted by the corresponding light source emitting unit in the light source emitting module 10, it can be understood that the third processing unit 122 can be used to process the original light source signal emitted by the corresponding light source emitting unit.

In short, the third processing unit 122 and the fourth processing unit 123 can respectively process the original light source signals emitted by the corresponding light source emitting units.

[0099] It should be noted that the first processing unit 120 and the third processing unit 122 may be the same processing unit or different processing units, which can be specifically set according to the actual situation and will not be specifically limited here. The second processing unit 121 and the fourth processing unit 123 may be the same processing unit or different processing units, which can be specifically set according to the actual situation and will not be specifically limited here. If the first processing unit 120 and the third processing unit 122 are the same processing unit, and the second processing unit 121 and the fourth processing unit 123 are the same processing unit, then the first original light source signal and the third original light source signal are the same original light source signal, the second original light source signal and the fourth original light source signal are the same original light source signal, the first target electrical signal and the third target electrical signal are the same target electrical signal, the second target electrical signal and the fourth target electrical signal are the same target electrical signal, the first target light energy signal and the third target light energy signal are the same target light energy signal, and the second target light energy signal and the fourth target light energy signal are the same target light energy signal. On this basis, Figure 5 and Figure 4 what is different is that Figure 5 in each processing unit can be communicatively connected to the multi-channel light energy display module 13, while Figure 4 in one processing unit is communicatively connected to another processing unit, and only the other processing unit can be communicatively connected to the multi-channel light energy display module 13. Correspondingly, Figure 5 in each processing unit can send the corresponding target light energy signal to the multi-channel light energy display module 13, while Figure 4 in the processing unit not communicatively connected to the multi-channel light energy display module 13 sends the target light energy signal corresponding to it to the processing unit communicatively connected to the multi-channel light energy display module 13, and the processing unit communicatively connected to the multi-channel light energy display module 13 sends all the target light energy signals to the multi-channel light energy display module 13.

[0100] Optionally, as Figure 7 shown, on the basis of the above technical solution, the light source emission module 10 may specifically include an ultraviolet light source emission unit 100, an infrared light source emission unit 101, a red light source emission unit 102, and a green light source emission unit 103. The light source reception module 11 may specifically include an ultraviolet light source reception unit 110, an infrared light source reception unit 111, a red light source reception unit 112, and a green light source reception unit 113. The target electrical signal may include a target ultraviolet electrical signal, a target infrared electrical signal, a target red electrical signal, and a target green electrical signal.

[0101] The ultraviolet light source receiving unit 110 can be communicatively connected to the first processing unit 120 via RS232. The infrared light source receiving unit 111 can be communicatively connected to the first processing unit 120 via RS485. The first processing unit 120 can be communicatively connected to the second processing unit 121 via RS422.

[0102] The first processing unit 120 can be configured to process the first target electrical signal to obtain a first target optical energy signal, and can send the first target optical energy signal to the second processing unit 121. Specifically, it can include:

[0103] The first processing unit 120 can be configured to process the target ultraviolet electrical signal and the target infrared electrical signal to obtain a target ultraviolet optical energy signal and a target infrared optical energy signal, and can send the target ultraviolet optical energy signal and the target infrared optical energy signal to the second processing unit 121. The target ultraviolet optical energy signal and the target infrared optical energy signal can serve as the first target optical energy signal.

[0104] The second processing unit 121 can be configured to process the second target electrical signal to obtain a second target optical energy signal, and can send the first target optical energy signal and the second target optical energy signal to the multi-channel optical energy display module 13. Specifically, it can include:

[0105] The second processing unit 121 can be configured to process the target red electrical signal and the target green electrical signal to obtain a target red optical energy signal and a target green optical energy signal. The target red optical energy signal and the target green optical energy signal can serve as the second target optical energy signal, and can send the first target optical energy signal and the second target optical energy signal to the multi-channel optical energy display module 13.

[0106] In an embodiment of the present invention, as Figure 7 shown, a structural schematic diagram of another optical energy display device is given. Figure 7Among them, the light source emission module 10 may specifically include an ultraviolet light source emission unit 100, an infrared light source emission unit 101, a red light source emission unit 102, and a green light source emission unit 103. The light source receiving module 11 may specifically include an ultraviolet light source receiving unit 110, an infrared light source receiving unit 111, a red light source receiving unit 112, and a green light source receiving unit 113. The target electrical signals may include a target ultraviolet electrical signal, a target infrared electrical signal, a target red electrical signal, and a target green electrical signal. The original light source information may include an original ultraviolet light source signal, an original infrared light source signal, an original red light source signal, and an original green light source signal. The target light energy signals may include a target ultraviolet light energy signal, a target infrared light energy signal, a target red light energy signal, and a target green light energy signal. Among them, the red light source emission module 102 may be a red light source emission module 102 with a wavelength of 650 nm. The green light source emission module 103 may be a green light source emission module with a wavelength of 532 nm.

[0107] The ultraviolet light source receiving unit 110 may be communicatively connected to the first processing unit 120 through RS232, and the infrared light source receiving unit 111 may be communicatively connected to the second processing unit 121 through RS485. The first processing unit 120 may be communicatively connected to the second processing unit 121 through RS422. Among them, RS232, RS485, and RS422 are standard interfaces. RS232 is a serial physical standard interface formulated by the Electronic Industries Association. RS is the abbreviation of Recommended Standard, and 232 is the identification number. RS232 is a regulation on electrical characteristics and physical characteristics, which acts on the data transmission path and does not include the data processing method. The electrical performance of RS485 is the same as the electrical characteristics of RS422. The main difference between the two is that RS485 has two signal lines, and the sending and receiving share the two signal lines. RS422 has four signal lines, two for sending and the other two for receiving. Since the sending and receiving of RS485 share the two signal lines, it cannot send and receive simultaneously, that is, it is a half-duplex working mode. Since the sending and receiving of RS422 are separated, it can send and receive simultaneously, that is, it is a full-duplex working mode.

[0108] The first processing unit 120 may process the first target electrical signal to obtain the first target light energy signal, and may send the first target light energy signal to the second processing unit 121. It can be understood as follows: The first processing unit 120 may process the target ultraviolet electrical signal and the target infrared electrical signal to obtain the target ultraviolet light energy signal and the target infrared light energy signal, and send the target ultraviolet light energy signal and the target infrared light energy signal to the second processing unit 121. Among them, the target ultraviolet light energy signal and the target infrared light energy signal may be used as the first target light energy signal.

[0109] The second processing unit 121 can process the second target electrical signal to obtain a second target optical energy signal, and can send the first target optical energy signal and the second target optical energy signal to the multi-channel optical energy display module 13. It can be understood as follows: The second processing unit 121 can process the target red electrical signal and the target green electrical signal to obtain a target red optical energy signal and a target green optical energy signal, can use the target red optical energy signal and the target green optical energy signal as the second target optical energy signal, and can send the first target optical energy signal and the second target optical energy signal to the multi-channel optical energy display module 13.

[0110] Optionally, on the basis of the above technical solution, the processing module 12 can be connected to the multi-channel optical energy display module 13 through a direct interface.

[0111] In an embodiment of the present invention, in order to avoid potential fault points such as communication interference and interruption, and to improve the stability of the optical energy display device 1, the communication connection method between the processing module 12 and the multi-channel optical energy display module 13 can be set to a direct interface connection method, that is, the processing module 12 can be connected to the multi-channel optical energy display module 13 through a direct interface.

[0112] The above processing module and the multi-channel optical energy display module are communicatively connected by means of a direct connection interface, which can avoid potential fault points such as communication interference and interruption, and improve the stability of the optical energy display device.

[0113] Optionally, on the basis of the above technical solution, the multi-channel optical energy display module 13 can be used to display the target optical energy signal, and specifically can include:

[0114] The multi-channel optical energy display module 13 can be used to display the target optical energy signal if the optical energy value of the target optical energy signal is greater than or equal to the optical energy threshold.

[0115] In an embodiment of the present invention, in order to further improve the accuracy of the light alignment detection result of the optical path in the motor vehicle exhaust remote sensing monitoring device, it can be considered to set that if the light energy value of the target light energy signal is greater than or equal to the light energy threshold, then the target light energy signal can pass through the LED light column 130 for display. Specifically: It can be considered that before the multi-channel light energy display module 13 displays the target light energy signal, it determines whether the light energy value of the target light energy signal is greater than or equal to the light energy threshold. If the multi-channel light energy display module 13 determines that the light energy value of the target light energy signal is greater than or equal to the light energy threshold, it can be explained that the optical path formed by the light source corresponding to the LED light column 130 in the motor vehicle exhaust remote sensing monitoring device has been adjusted properly, that is, the light alignment detection result is that the optical path is normal, and further it can be explained that the motor vehicle exhaust remote sensing monitoring device is in a normal working state. Correspondingly, the multi-channel light energy display module 13 can display the target light energy signal. If the multi-channel light energy display module 13 determines that the light energy value of the target light energy signal is less than the light energy threshold, it can be explained that the optical path formed by the light source corresponding to the LED light column 130 in the motor vehicle exhaust remote sensing monitoring device has not been adjusted properly, that is, the light alignment detection result is that the optical path is abnormal, and further it can be explained that the motor vehicle exhaust remote sensing monitoring device is in an abnormal working state. Correspondingly, the display module 13 may not display the target light energy signal. From another perspective, if the target multi-channel light energy display module 13 displays the target light energy signal, it can be explained that the target light energy signal is greater than or equal to the light energy threshold. If the target display module 13 does not display, it can be explained that the target light energy signal is less than the light energy threshold. Among them, the light energy threshold can be used as a basis for determining the light alignment detection result of the optical path in the motor vehicle exhaust remote sensing monitoring device, and further the light energy threshold can be used as a basis for determining the working state of the motor vehicle exhaust remote sensing monitoring device. The numerical value of the light energy threshold can be set according to the actual situation and will not be specifically limited here.

[0116] It should be noted that since the light source emission module 10 may include at least one light source emission unit, correspondingly, the number of original light source signals is at least one. On this basis, the number of target light energy signals is also at least one, and each LED light column 130 in the multi-channel light energy display module 13 can be used to display the target light energy signal corresponding to the LED light column 130. Therefore, the working state of each light source emission unit in the motor vehicle exhaust remote sensing monitoring device configured in the light energy display device 1 can be determined according to the display state of each LED light column 130. In other words, for each LED light column 130 in the multi-channel light energy display module 13, if the LED light column 130 does not display the target light energy signal corresponding to the LED light column 130, it can be indicated that the light source emission unit corresponding to the LED light column 130 is not in a normal working state, that is, in an abnormal working state. At this time, the light energy value of the target light energy signal corresponding to the LED light column 130 will be less than the light energy threshold. If the LED light column 130 displays the target light energy signal corresponding to the LED light column 130, it can be indicated that the light source emission unit corresponding to the LED light column 130 is in a normal working state. At this time, the light energy value of the target light energy signal corresponding to the LED light column 130 will be greater than or equal to the light energy threshold.

[0117] It should also be noted that a light energy threshold corresponding to each target light energy signal can be set. The light energy thresholds of different target light energy signals can be equal or unequal, and can be specifically set according to actual situations, and no specific limitations are made here. Exemplarily, if the target light energy signals include a target ultraviolet light energy signal, a target infrared light energy signal, a target red light energy signal, and a target green light energy signal. The above different target light energy signals are respectively provided with corresponding light energy thresholds, which are an ultraviolet light energy threshold, an infrared light energy threshold, a red light energy threshold, and a green light energy threshold. And it is set that the different light energy thresholds are unequal.

[0118] Figure 8 FIG. is a schematic structural diagram of a motor vehicle exhaust remote sensing monitoring device provided by an embodiment of the present invention. This embodiment is applicable to the situation of improving the integration degree and long-distance recognition degree of the light energy display device, such as Figure 8 as shown, the positioning system may specifically include the light energy display device 1 described in the embodiment of the present invention, and may specifically further include an exhaust gas monitoring device 2. Its structure and function will be described below.

[0119] The light energy display device 1 can be communicatively connected to the exhaust gas monitoring device 2.

[0120] The light energy display device 1 can be used to determine the light alignment detection result of the optical path in the exhaust gas monitoring device 2.

[0121] The exhaust gas monitoring device 2 can be used to monitor motor vehicle exhaust gas.

[0122] In an embodiment of the present invention, the light energy display device 1 can be used to determine the optical alignment detection result of the optical path in the exhaust gas monitoring device 2 of the motor vehicle exhaust remote sensing monitoring equipment according to whether the light energy display module 13 ( Figure 8 not shown) can display the target light energy signal, so as to determine whether the motor vehicle exhaust remote sensing monitoring equipment is in a normal working state. When it is determined that the optical alignment result of the optical path in the exhaust gas monitoring device 2 of the motor vehicle exhaust remote sensing monitoring equipment is normal, the exhaust gas monitoring device 2 can monitor the motor vehicle exhaust gas.

[0123] The technical solution of this embodiment can achieve the simultaneous centralized display of the target light energy signals of the light sources used in the motor vehicle exhaust remote sensing monitoring equipment by setting the multi-channel light energy display module 13 including at least one LED light column 130, improving the integration degree of the light energy display device 1. Moreover, since the LED light column 130 is made of a high-brightness digital tube and a special light guide material, using the LED light column 130 to display the target light energy signal improves the long-distance recognition degree of the light energy display device 1, and further reduces the difficulty of the optical alignment detection for the optical path in the motor vehicle exhaust remote sensing monitoring equipment.

[0124] Optionally, on the basis of the above technical solution, the motor vehicle exhaust remote sensing monitoring equipment may include a fixed horizontal motor vehicle exhaust remote sensing monitoring equipment and a mobile motor vehicle exhaust remote sensing monitoring equipment.

[0125] In an embodiment of the present invention, the motor vehicle exhaust remote sensing monitoring equipment can be divided into a fixed motor vehicle exhaust remote sensing monitoring equipment and a mobile motor vehicle exhaust remote sensing monitoring equipment according to the usage category. Among them, the fixed motor vehicle exhaust remote sensing monitoring equipment may include a fixed horizontal motor vehicle exhaust remote sensing monitoring equipment. The single optical path of the fixed horizontal motor vehicle exhaust remote sensing monitoring equipment is the longest, which can reach 12m - 15m.

[0126] The above specific embodiments have further detailed the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
