DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0022] The present application embodiment provides a method for controlling lighting in a traffic tunnel. Figure 1 As shown, the lighting control method for a traffic tunnel specifically includes steps S101-S106: S101. According to the segmented scenes of a preset traffic tunnel, regional visibility data in each segmented scene is collected.

[0023] Specifically, firstly, it is necessary to represent the light-dark variation law data inside the traffic tunnel according to the tunnel length of the traffic tunnel, and determine the light-dark adaptation curve, wherein the horizontal axis of the light-dark adaptation curve is the tunnel length, and the vertical axis of the light-dark adaptation curve is the light-dark variation law data.

[0024] Furthermore, the light-dark adaptation curve is converted into a gradient curve under a relevant slope range change to obtain a step change curve.

[0025] In one embodiment, based on the step-changing curve under the change of light and dark, the segmented scenes can be better divided, that is, the curve segment with a certain range of step-changing is defined as a segmented scene, and then the overall division of all traffic tunnels is completed.

[0026] Furthermore, based on the preset step change range, the step change curve is segmented into regions to determine segmented scenes, wherein the segmented scenes include: an entrance region scene, an entrance transition region scene, an intermediate region scene, an exit transition region scene, and an exit scene.

[0027] Furthermore, it is also necessary to utilize a number of visibility sensors in each segmented scene and collect regional visibility data in each segmented scene based on a preset time interval.

[0028] S102: Based on the external light data of the traffic tunnel, perform tunnel lighting feature analysis on the regional visibility data to determine first control data for adjusting the lighting.

[0029] Specifically, firstly, external light data is collected based on the light sensor installed outside the tunnel. And the current meteorological data is determined according to the meteorological area where the traffic tunnel is located. The external light data and the current meteorological data are data-fused, analyzed and the external visibility data is obtained. Then, the external visibility data and the regional visibility data in the first regional scene are subjected to feature matching processing between the data to obtain the first compensation lighting parameter based on the first regional scene. Among them, the first regional scene includes: the entrance regional scene and the exit regional scene. And according to the first compensation lighting parameter, the lighting is controlled and adjusted to obtain the first control data in the first regional scene.

[0030] Furthermore, the first compensation area visibility data in the first area scene under the control of the first compensation lighting parameter is obtained, and the first compensation area visibility data is subjected to feature matching processing with the area visibility data in the second area scene to determine the second compensation lighting parameter in the second area scene. The second area scene includes an entrance transition area scene and an exit transition area scene.

[0031] Further, based on the second compensation lighting parameter, first control data in the second area scene is determined.

[0032] Furthermore, according to the second compensation area visibility data under the second compensation lighting parameter, feature matching processing is performed on the area visibility data in the middle area scene, and based on the third compensation lighting parameter, the first control data in the middle area scene is determined.

[0033] In one embodiment, by calculating the correlation of visibility data of different regional scenes, the lighting in each regional scene can be controlled and adjusted for the first time under the environmental data, and based on the gradual decrease of visibility or brightness data of different regional scenes, and the correlation between different regional scenes, the first control data in different regional scenes are linked together. Based on the compensation lighting parameters, the control and adjustment of the lighting in different regional scenes is also realized, and finally the preliminary control data of the lighting after the analysis of the tunnel lighting characteristics, that is, the first control data, can be obtained. It can better utilize external light or traffic conditions in the tunnel to adjust the lighting in time, lay a data foundation for improving the visual adaptability of drivers, and is conducive to further improving the safe driving of tunnel vehicles in the future.

[0034] S103: Perform membership analysis on the regional traffic flow data in each segmented scene to determine lighting brightness optimization parameters based on fuzzy rules.

[0035] Specifically, it is necessary to first collect regional traffic flow data in each segmented scene, wherein the regional traffic flow data includes: vehicle speed data and traffic volume data.

[0036] Furthermore, combined with the preset Gaussian membership function, the variable value change trend between the regional traffic flow data and the regional visibility data in each segmented scene is calculated to determine the mapping membership of the regional traffic flow element in the regional visibility element.

[0037] Furthermore, according to the mapping membership, the required lighting brightness parameters in the current segmented scene are fuzzy processed to determine the ideal lighting brightness parameters.

[0038] Furthermore, the ideal lighting brightness parameter is compared with the actual lighting brightness parameter in the current segmented scene to determine the lighting brightness optimization parameter in the current segmented scene, wherein the lighting brightness optimization parameter is used to optimize and adjust the lighting light.

[0039] As a feasible implementation method, Gaussian function is a commonly used membership function, which is widely used in fuzzy logic and fuzzy set theory. The function describes the trend of membership changing with the increase of variable value in the form of Gaussian distribution curve. In fuzzy set theory, the membership function describes the degree of membership of an element in a fuzzy set. For a given element, the membership function measures its similarity with the fuzzy set by mapping the element to a real number between 0 and 1. Gaussian function is usually used to describe the membership of the center of a fuzzy set.

[0040] S104: Compensate and control the lighting brightness of the lighting light by optimizing the lighting brightness parameters to obtain second control data for compensating the lighting light.

[0041] Specifically, a curve fitting analysis is performed on the actual road brightness and the actual visibility in the current segmented scene to obtain the road brightness fitting value in the current segmented scene. Then, according to the lighting brightness optimization parameter, the road brightness fitting value is difference calculated to obtain the lighting brightness loss rate in the current segmented scene.

[0042] Furthermore, finally, the lighting light is subjected to power increase and decrease compensation processing through the lighting brightness loss rate, and power compensation data is determined. The power compensation data is subjected to control instruction conversion to obtain second control data.

[0043] In one embodiment, the visibility level in a highway tunnel has a great influence on the conversion efficiency of the lighting brightness of the lamps. For different visibility environments, if the same lighting conditions are adopted, the road surface brightness in the tunnel will not reach the design value, which will bury a safety hazard. Therefore, a curve fitting analysis is performed on the measured actual road surface brightness and actual visibility in the tunnel to obtain the road surface brightness fitting value in the current segmented scene, which can meet the lighting optimization requirements of safety and energy saving. At the same time, adaptive control can be achieved for the regional traffic flow data in each segmented scene. The corresponding lighting control strategy can be adjusted according to the different traffic flows to achieve further control of the tunnel lighting fixtures.

[0044] S105. Using a preset dynamic brightness model, the external light data and the regional traffic flow data are used to predict the partial correlation of brightness under the optimal human visual experience, and the optimal experience brightness data is determined.

[0045] Specifically, a preset neural network model is used to train the historical light data set and the historical human vision data set under the multi-factor coupling correlation model to obtain a brightness dynamic model. The multi-factors include at least: light intensity, light source color, human eye light perception, and human eye light comfort.

[0046] Furthermore, the external light data is input into the brightness dynamic model to determine the visual optimal brightness data corresponding to the external light data.

[0047] Furthermore, the ideal tunnel light data corresponding to the current area traffic flow data is used to predict the human visual brightness through the brightness dynamic model to obtain the theoretical optimal brightness data.

[0048] Furthermore, it is also necessary to perform partial correlation analysis and calculation on the visual optimal brightness data and the theoretical optimal brightness data in relation to brightness to obtain a partial correlation coefficient. Based on the partial correlation coefficient, the optimal experience brightness data between the visual optimal brightness data and the theoretical optimal brightness data is determined.

[0049] As a feasible implementation method, partial correlation analysis is used to calculate the correlation between two variables under the influence of other variables. It can identify and quantify the direct relationship between two variables and eliminate the interference of other variables on their relationship. In correlation analysis, the correlation coefficient is usually used to analyze or measure the degree of linear correlation between these variables. However, the simple correlation coefficient is affected by other factors and often reflects non-essential connections. To accurately reflect the intrinsic connection between two economic variables, it is necessary to calculate the partial correlation coefficient. By comparing the partial correlation coefficient with the correlation coefficient, it will be more real and reliable to determine the intrinsic linear connection between the two variables.

[0050] S106: Adaptively adjust the control parameters of the first control data and the second control data according to the best experience brightness data to obtain optimal brightness control data in each segmented scene.

[0051] Specifically, firstly, the best control data is determined based on the best experience brightness data. According to the best control data, the first control data and the second control data are decentralized to obtain the first control authority and the second control authority. Then, according to the first control authority, the second control authority is linked to follow control to determine the second follow control authority. Then, through the first control authority and the second follow control authority, the control strategy of the lighting in each segmented scene is adaptively adjusted to obtain the optimal brightness control data.

[0052] As a feasible implementation, in the middle area scene of the segmented scene, the control strategy corresponding to the second control data is determined as the optimal brightness control strategy in the middle area scene. Based on the optimal brightness control strategy, the optimal brightness control data in the middle area scene is obtained.

[0053] In addition, the present application also provides a lighting control device for a traffic tunnel, such as Figure 2 As shown, the lighting control device 200 of the traffic tunnel specifically includes: At least one processor 201. And a memory 202 in communication with the at least one processor 201. The memory 202 stores instructions that can be executed by the at least one processor 201, so that the at least one processor 201 can execute: According to the segmented scenes of the preset traffic tunnel, the regional visibility data in each segmented scene is collected; Based on the external light data of the traffic tunnel, the tunnel lighting characteristics are analyzed on the regional visibility data to determine the first control data for adjusting the lighting; Perform membership analysis on the regional traffic flow data in each segmented scene to determine the lighting brightness optimization parameters based on fuzzy rules; By optimizing the lighting brightness parameters, the lighting brightness of the lighting light is compensated and controlled to obtain second control data for compensating the lighting light; Through the preset dynamic brightness model, the external light data and the regional traffic flow data are used to predict the partial correlation of brightness under the optimal human visual experience, and the optimal experience brightness data is determined; According to the best experience brightness data, the control parameters of the first control data and the second control data are adaptively adjusted to obtain the optimal brightness control data in each segmented scene.

[0054] The embodiment of the present application can improve the visual effect in the tunnel, reduce the driver's blind spots and visual fatigue, and thus improve traffic safety by controlling the lighting according to the regional visibility data. And by optimizing the lighting brightness according to the traffic flow data and fuzzy rules, the brightness of the lighting can be adjusted according to actual needs, avoiding energy waste and reducing energy costs. By predicting the best experience brightness data and adjusting the control parameters according to the data, the lighting brightness that is most suitable for the human eye can be provided, improving the driver's comfort and visual experience.
