Description

Technical Field

[0001] The present invention relates to the technical field of tunnel lighting management, and in particular to a tunnel electricity consumption analysis and lighting management system. Background Art

[0002] With the rapid development of highway traffic, highway tunnels are increasing day by day, and the quality of tunnel lighting directly affects traffic safety. At present, most tunnel lighting control and management still adopt a relatively backward mode. The existing highway tunnel lighting system is relatively simple and has a fixed control mode. It is not flexible enough, and the phenomenon of ineffective lighting and excessive lighting is particularly prominent due to the difficulty in achieving optimal control.

[0003] In terms of energy conservation and emission reduction in tunnel lighting, the current existing technology has formed an intelligent lighting system that "lights follow the car". Through advanced equipment and technologies such as the Internet of Things, cloud computing, brightness detectors, millimeter-wave radar, license plate capture, geomagnetic induction, and event monitoring "four-in-one" vehicle tracking and identification system, the system automatically captures vehicle traffic information, follows the vehicle's driving trajectory, and dynamically adjusts the lighting space in front and behind the vehicle until the vehicle safely exits the tunnel. When there are no vehicles passing, the system automatically adjusts the light brightness to meet the minimum standard requirements for highway tunnel lighting, realizing segmented precise control of lights turning on when a car comes and dimming when a car leaves, and lights following the car.

[0004] Although this method can effectively reduce energy consumption, it only considers controlling the lights based on whether there are vehicles, that is, turning on the lights when there are vehicles and turning off the lights when there are no vehicles. However, it does not consider adjusting the brightness of the lights when there are vehicles to further save electricity. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a tunnel electricity consumption analysis and lighting management system. When there are vehicles in the tunnel, the brightness of the lighting surface in the tunnel is adjusted according to the number of vehicles, thereby further saving the power consumption of the tunnel lighting equipment.

[0006] The basic solution provided by the present invention is: a tunnel electricity consumption analysis and lighting management system, including a tunnel sensing device and a server, wherein the tunnel sensing device is used to collect the ambient brightness of the tunnel entrance and exit, the tunnel light brightness, and the vehicle flow and upload them to the server; The server includes a lighting management module; The lighting management module is used to divide the tunnel into multiple sections, identify the traffic data in each section, and adjust the tunnel light brightness of each section according to the traffic data in the section, the ambient brightness of the entrance and exit, and the tunnel light brightness of each section of the tunnel; The lighting management module includes a brightness management module and a device adjustment module; The brightness management module sets the maximum and minimum brightness of each section according to the ambient brightness of the entrance and exit, and sets the number of lighting devices to be turned on for the minimum brightness requirement. , the number of lighting devices with minimum brightness requirements turned on ; The equipment adjustment module is used to monitor the number of vehicles in each section according to the traffic data of each section. When there are no vehicles in the section, the number of lighting devices in the corresponding section is controlled to be turned on. When there are vehicles in the interval, the number of lighting devices turned on is controlled according to the number of vehicles in the interval. The more vehicles there are, the closer the number of open , the fewer the number of vehicles, the closer .

[0007] The principle and advantage of the present invention is that the minimum brightness and maximum brightness are set for each section in the tunnel, and the number of lighting devices turned on to meet the highest brightness requirement is set. , and the number of lighting devices turned on with minimum brightness requirements When there are no vehicles in the tunnel, the tunnel is illuminated at the lowest brightness. After that, the number of vehicles in the section is identified based on the traffic data, and the number of lighting devices turned on is determined based on the number of vehicles. and Since the vehicle lights can also provide lighting, when the number of vehicles is small, the lighting provided by the lights is small, so it is ensured that the number of turned-on lighting devices is sufficient. When the number of vehicles is large, the lighting provided by the lights is large, so a certain number of lighting devices can be turned off.

[0008] Compared with the prior art, the present application adjusts and controls the number of turned-on lighting devices according to the number of vehicles, and reasonably reduces the number of turned-on lighting devices based on the lighting brightness provided by the vehicle's own headlights, thereby further reducing the power consumption in the tunnel.

[0009] Furthermore, the interval section includes an entrance section, an entrance transition section, a middle section, an exit transition section and an exit section from the tunnel entrance to the tunnel exit; the middle section is preset with a rated maximum brightness. and rated minimum brightness ; The brightness management module is a rated brightness setting module. Rated brightness setting module, used to adjust the brightness according to the ambient brightness , set the maximum brightness of the exit and entrance segments and minimum brightness , Higher than Higher than ; According to the highest and lowest brightness of the entrance section, exit section and middle section, set the highest brightness of the entrance transition section and exit transition section and minimum brightness ,make lie in and between, lie in and between.

[0010] The rated maximum brightness and rated minimum brightness are preset in the middle section, and the maximum brightness and minimum brightness of the entrance section and exit section are set according to the ambient brightness at the tunnel entrance and exit, so that when the vehicle enters or leaves the tunnel, the brightness inside the tunnel is closer to the brightness outside the tunnel, avoiding the black hole effect and white hole effect for the driver. The entrance transition section and exit transition section play a buffering role for the driver, allowing the driver to gradually adapt to the brightness changes.

[0011] Furthermore, the vehicle acquisition module is used to identify the number of vehicles and vehicle density in the interval segment according to the traffic flow data in the interval segment; The lighting control module is used to control the number of lighting devices to be turned on when the vehicle density in the interval is less than a preset density threshold. When the vehicle density is higher than the preset density threshold, the number of lighting devices turned on is controlled according to the number of vehicles. The more vehicles there are, the closer the number of lighting devices turned on is. .

[0012] Furthermore, the tunnel sensing device is also used to collect the power consumption of the lighting equipment, and the server also includes a power consumption analysis module, which includes an interval analysis module, a time period analysis module and a total amount analysis module; The interval analysis module is used to calculate the power consumption of lighting equipment in each interval within the cycle according to the power consumption of lighting equipment in the interval; The time period analysis module is used to calculate the power consumption of the lighting equipment in each period within the cycle according to the power consumption of the lighting equipment in each period; The total amount analysis module is used to calculate the total power consumption within a period based on the power consumption of lighting equipment.

[0013] By acquiring the power consumption of the lighting equipment in the tunnel, statistics are collected for each interval, time period and total power consumption within the cycle.

[0014] Further, the server also includes an abnormality identification module, and the abnormality identification module includes an abnormality identification module and an abnormality judgment module; An abnormality identification module is used to identify the intervals and time periods in the current cycle where the power consumption is higher than that in the previous cycle when the growth rate of the total power consumption in the cycle exceeds a preset ratio compared to the total power consumption in the previous cycle; The abnormality judgment module is used to obtain the number of vehicles in the corresponding interval and the corresponding time period. If the number of vehicles is lower than the number of vehicles in the corresponding time period and the corresponding interval of the previous cycle, it is marked as normal, otherwise it is marked as abnormal.

[0015] When the total power consumption in a cycle increases significantly compared to the total power consumption in the previous cycle, it is identified which time period and which interval in this cycle has an increase in power consumption compared to each time period and each interval in the previous cycle. In this application, the number of cameras turned on is controlled according to the number of vehicles, so it is identified whether there is a decrease in the corresponding interval and the corresponding time period in this cycle compared to the previous cycle. If so, the power consumption is a normal increase, otherwise it is abnormal. BRIEF DESCRIPTION OF THE DRAWINGS
