Description

Technical Field

[0001] This invention relates to the field of smart city monitoring technology, and in particular to a smart lighting automatic alarm system based on environmental monitoring. Background Technology

[0002] Due to the expanding application of intelligent computer control technology, it is commonly used in urban construction and management. This facilitates the development of smart cities, which originated in the media field. Smart cities refer to the application of intelligent computing technologies such as the Internet of Things, cloud computing, big data, and geospatial information integration in urban planning, design, construction, management, and operation. This makes key infrastructure components and services of cities, including urban management, education, healthcare, real estate, transportation, public utilities, and public safety, more interconnected, efficient, and intelligent. Ultimately, this provides citizens with better living and working services, creates a more favorable business environment for enterprises, and empowers governments with more efficient operation and management mechanisms.

[0003] In the current technological field, during the construction of smart cities, monitoring equipment, signaling equipment, and data acquisition equipment are added to existing lighting systems to improve their functionality. However, existing lighting systems fall far short of the role of smart alarms. The collected data is all single-point data collection, and the backend processing of the data is only used for single-point comparison. In some severe weather conditions, it is impossible to achieve coordinated early warning within the area. Early warning control still relies on manual division of warning areas based on human judgment. Therefore, the alarm function of existing lighting systems is simple, the regional coordination is poor, and the actual alarm accuracy and effectiveness are low. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention integrates and analyzes visibility, rainfall, and snowfall information obtained from lighting modules, enabling coordinated alarm processing within areas where several lighting modules are located. This improves the timeliness and accuracy of early warnings for roads where several lighting modules are located, thus solving the problems of low functional integration capabilities and insufficient intelligence and coordination in existing urban lighting systems.

[0015] The ambient visibility obtained from several lighting modules within a Level 3 visibility area is acquired and set as the Level 3 area visibility; the average value of several Level 3 area visibility values ​​is calculated and set as the Level 3 area visibility reference value; the length of the Level 3 visibility area is acquired and set as the Level 3 area length; the Level 3 area length and the Level 3 area visibility reference value are used to calculate the Level 3 warning division reference value using the Level 3 warning division formula; the Level 3 warning division formula is configured as follows: Where Cy3 is the reference value for the three-level warning division, S3 is the length of the three-level area, V3 is the reference value for the visibility of the three-level area, c1 is the warning weight for the length of the three-level area, c2 is the warning weight for the visibility of the three-level area, c1+c2=1, and both c1 and c2 are greater than zero.

[0016] The reference values ​​for classifying Level 1, Level 2, and Level 3 early warnings are uniformly set as early warning level comparison reference values.

[0017] When the warning level comparison reference value is greater than or equal to the first warning threshold, it is classified as a Level 1 warning; when the warning level comparison reference value is greater than or equal to the second warning threshold and less than the first warning threshold, it is classified as a Level 2 warning; when the warning level comparison reference value is less than the second warning threshold, it is classified as a Level 3 warning.

[0021] Furthermore, the alarm unit includes an alarm display device, and the alarm unit is configured with a visibility alarm strategy, the visibility alarm strategy including: setting a first speed limit information, a second speed limit information and a third speed limit information for the first-level alarm signal, the second-level alarm signal and the third-level alarm signal respectively;

[0023] Furthermore, the comprehensive alarm strategy also includes a rainfall alarm setting sub-strategy, which includes: when the acquired environmental rainfall is greater than or equal to a first rainfall threshold, setting the acquired time point as the rainfall statistics start point, and accumulating the environmental rainfall from the rainfall statistics start point to obtain the real-time accumulated rainfall.

[0024] The real-time acquired ambient rainfall and real-time accumulated rainfall are used to calculate the rainfall level reference value using the rainfall level calculation formula; the rainfall level calculation formula is configured as follows: Where Cjy is the rainfall level reference value, Jys is the real-time environmental rainfall, JyL is the real-time cumulative rainfall, d1 is the real-time rainfall warning weight, d2 is the cumulative rainfall warning weight, d1+d2=1, and both d1 and d2 are greater than zero.

[0029] When the snowfall level reference value is greater than or equal to the first snowfall reference threshold, it is classified as Level 1 snowfall; when the snowfall level reference value is greater than or equal to the second snowfall reference threshold and less than the first snowfall reference threshold, it is classified as Level 2 snowfall; when the snowfall level reference value is less than the second snowfall reference threshold, it is classified as Level 3 snowfall.

[0033] The alarm display device displays the corresponding first speed limit information, second speed limit information, and third speed limit information.

[0034] The beneficial effects of this invention are:

[0035] 1. This invention obtains environmental visibility, environmental rainfall, and environmental snowfall through an environmental monitoring unit. These three sets of environmental data can have a significant impact on road traffic in the area where the lighting module is located, thus improving the effectiveness of data acquisition for automatic alarms.

[0036] 2. This invention processes the monitoring data obtained by the environmental monitoring unit to obtain monitoring results. Based on the monitoring results, key areas on the distribution path are marked. This design can divide different visibility areas. Specifically, the visibility area is divided into three levels according to its length. The advantage of this division is that if the entire area is in a situation of low visibility over a large area, the vehicle itself will issue an early warning. At the same time, the risk is also high. If there is a situation where the visibility is low in some areas but normal in others, the danger is also high because the visibility changes greatly. During vehicle operation, the driver needs to react in a short time, which is also more dangerous. Therefore, through the above division, different situations can be targeted, which helps to improve the accuracy and effectiveness of the warning.

[0037] 3. Furthermore, this invention further improves the accuracy of alarm judgment by classifying the monitoring and processing results into early warning levels, setting alarm ranges for key areas based on the early warning levels of the monitoring and processing results, and outputting the alarm ranges to the alarm unit. By incorporating the severity of the environmental data into the alarm data, this invention can further improve the accuracy of alarm judgment.

[0038] Advantages of additional aspects of the invention will be set forth in part in the detailed description of the invention below, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0043] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0045] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0046] Please see Figure 1 As shown, this invention provides a smart lighting automatic alarm system based on environmental monitoring. This system integrates and analyzes the visibility, rainfall and snowfall information obtained from the lighting modules, and can perform coordinated alarm processing in the area where several lighting modules are located, thereby improving the timeliness and accuracy of early warnings for roads where several lighting modules are located.

[0047] Specifically, the intelligent lighting automatic alarm system based on environmental monitoring of the present invention includes a processing terminal and several lighting modules, each of which is communicatively connected to the processing terminal; for specific implementation, please refer to... Figure 2 As shown, the lighting module is set as a smart street light device 1, and the processing terminal is a back-end server. The smart street light device 1 can be equipped with street lights 11, traffic lights 12, display screen 13 and environmental collector 14. The display screen 13 corresponds to the alarm display device in this system, and the environmental collector 14 corresponds to the environmental monitoring unit in this system. When no alarm is needed, the display screen 13 can be used to display promotional information and municipal information, etc.

[0048] The lighting module includes an environmental monitoring unit and an alarm unit. The environmental monitoring unit includes a visibility meter, a rain gauge, and a snow gauge. The visibility meter is used to obtain environmental visibility, the rain gauge is used to obtain environmental rainfall, and the snow gauge is used to obtain environmental snowfall. In practice, the unit for environmental visibility is meters (m), and the lower the environmental visibility, the worse the environmental visibility. The unit for environmental rainfall is millimeters (mm), and the unit for environmental snowfall is millimeters (mm). Among these, rainfall has a greater impact on traffic due to real-time rainfall, which affects driving visibility. Snowfall has a greater impact on traffic due to cumulative snowfall, which accumulates on the road surface, reduces road friction, and thus affects traffic.

[0049] The processing terminal includes a distributed analysis unit and a comprehensive alarm control unit. The distributed analysis unit is configured with a distributed analysis strategy, which includes processing the monitoring data acquired by the environmental monitoring unit to obtain monitoring processing results, and marking key areas on the distribution path based on the monitoring processing results. The distributed analysis strategy also includes a visibility distribution model establishment sub-strategy, which includes: acquiring the environmental visibility once every first monitoring time interval; when the environmental visibility is less than a first visibility threshold, marking it as alarm visibility, and setting the lighting module where the alarm visibility is located as the alarm reference point.

[0050] Starting from the alarm reference point, the ambient visibility collected by the lighting modules on both sides of the alarm reference point is obtained sequentially. When the obtained ambient visibility is less than the first visibility threshold, the ambient visibility of the next adjacent lighting module is compared until the obtained ambient visibility is greater than the first visibility threshold, at which point the comparison stops.

[0051] Set several consecutive lighting modules with environmental visibility less than the first visibility threshold as visibility alarm zones;

[0052] Obtain the length of the visibility alarm area;

[0053] When the length of the visibility alarm area is greater than or equal to the first length threshold, the visibility alarm area is set as a Level 1 visibility area; when the length of the visibility alarm area is greater than or equal to the second length threshold and less than the first length threshold, the visibility alarm area is set as a Level 2 visibility area; when the length of the visibility alarm area is less than the second length threshold, the visibility alarm area is set as a Level 3 visibility area. The first visibility threshold is set to 2000m. When the detected environmental visibility is less than 2000m, a focus area needs to be divided, with the first length threshold set to 1000m and the second length threshold set to 50m. Typically, streetlights are spaced 50m apart, therefore, when setting... When setting the first and second length thresholds, they are set in multiples of 50. The secondary visibility area between 50m and 1000m is a patchy fog area, which gives drivers a short reaction time and is highly dangerous. If the distance is less than 50m, even if patchy fog occurs, vehicles will pass through it in a short time, and the impact is smaller than that of the secondary visibility area. The primary visibility area is a situation where the visibility is generally low in a region. In this case, drivers will have an early warning, so the danger will be reduced. However, because it covers a wide area, if the visibility is very low, its impact will still be higher than that of the secondary and tertiary visibility areas.

[0054] The integrated alarm control unit is configured with an integrated alarm strategy, which includes: classifying monitoring and processing results into warning levels; setting alarm ranges for key areas based on the warning levels of the monitoring and processing results; and outputting the alarm ranges to the alarm unit. The integrated alarm strategy also includes a visibility warning level classification sub-strategy, which includes: acquiring the environmental visibility obtained by several lighting modules within a first-level visibility area and setting it as the first-level area visibility; calculating the average of several first-level area visibility values ​​and setting it as the first-level area visibility reference value; acquiring the length of the first-level visibility area and setting it as the first-level area length; and using the first-level area length and the first-level area visibility reference value to obtain the first-level warning classification reference value through a first-level warning classification formula. The first-level warning classification formula is configured as follows: Where Cy1 is the reference value for the first-level warning division, S1 is the length of the first-level area, V1 is the visibility reference value of the first-level area, a1 is the warning weight for the length of the first-level area, a2 is the warning weight for the visibility of the first-level area, a1+a2=1, and both a1 and a2 are greater than zero; k1 is the length warning conversion coefficient, and k2 is the visibility warning conversion coefficient; k1 and k2 are constants, and both k1 and k2 are greater than zero. In setting the reference value for the first-level warning division, a2 must be greater than a1. The reason is that even if the length of the first-level visibility area is very long, i.e., the coverage area is very wide, as long as the visibility is not very low, its impact will not be too great. However, once the visibility is very low, the corresponding impact will be great. Specifically, a2 is set to 0.7, and a1 is set to 0.3. When converting the length of the area, k1 is set to 0.1, and k2 is set to 10000. For example, if S1 is 2000 and V1 is 100, the reference value for the first-level warning division is 130 according to the above settings.

[0055] The ambient visibility obtained by several lighting modules within a secondary visibility area is acquired and set as the secondary area visibility; the average value of several secondary area visibility values ​​is calculated and set as the secondary area visibility reference value; the length of the secondary visibility area is acquired and set as the secondary area length; the average value of the ambient visibility of the first number of adjacent lighting modules on both sides of the secondary visibility area is calculated and set as the variable visibility reference value; the secondary area length, the secondary area visibility reference value, and the variable visibility reference value are used to obtain the secondary warning division reference value through the secondary warning division formula; the secondary warning division formula is configured as follows: Where Cy2 is the reference value for the secondary warning division, S2 is the length of the secondary area, V2 is the reference value for visibility in the secondary area, Vb is the reference value for changing visibility, b1 is the warning weight for the length of the secondary area, b2 is the warning weight for visibility in the secondary area, b3 is the warning weight for the visibility difference, b1+b2+b3=1, and b1, b2 and b3 are all greater than zero. In specific implementation, b3 is greater than b2, and b2 is greater than b1. The reason for this setting is that if the visibility difference between two adjacent areas is high, the impact of a vehicle entering a poorly visible area from an area with good visibility is significant, thus requiring a higher level of driver reaction. In specific settings, b3 is set to 0.5, b2 is set to 0.3, and b1 is set to 0.2.

[0056] Obtain the ambient visibility from several lighting modules within the Level 3 visibility area and set it as the Level 3 area visibility; calculate the average of several Level 3 area visibility values ​​and set it as the Level 3 area visibility reference value; obtain the length of the Level 3 visibility area and set it as the Level 3 area length; use the Level 3 area length and the Level 3 area visibility reference value to calculate the Level 3 warning classification reference value using the Level 3 warning classification formula; the Level 3 warning classification formula is configured as follows: Where Cy3 is the reference value for the three-level warning division, S3 is the length of the three-level area, V3 is the reference value for visibility in the three-level area, c1 is the warning weight for the length of the three-level area, and c2 is the warning weight for visibility in the three-level area. c1+c2=1, and both c1 and c2 are greater than zero. In specific settings, c2 is set to 0.8 and c1 is set to 0.2. When poor visibility occurs at short distances, the lower the visibility, the greater the impact.

[0057] The reference values ​​for classifying Level 1, Level 2, and Level 3 early warnings are uniformly set as early warning level comparison reference values.

[0058] When the warning level comparison reference value is greater than or equal to the first warning threshold, it is classified as a Level 1 warning; when the warning level comparison reference value is greater than or equal to the second warning threshold and less than the first warning threshold, it is classified as a Level 2 warning; when the warning level comparison reference value is less than the second warning threshold, it is classified as a Level 3 warning. In specific implementation, the Level 1 warning threshold is set to 150, and the Level 2 warning threshold is set to 50.

[0059] The comprehensive alarm strategy also includes a visibility alarm range setting sub-strategy, which includes setting a first alarm range, a second alarm range, and a third alarm range for the visibility areas where the first, second, and third warning levels are located, respectively; specifically, the first alarm range, the second alarm range, and the third alarm range are set to 10km, 5km, and 1km, respectively.

[0060] The first alarm range is larger than the second alarm range, and the second alarm range is larger than the third alarm range;

[0061] A Level 1 alarm signal is output to the lighting modules within the first alarm range on both sides of the visibility area corresponding to the Level 1 warning level; a Level 2 alarm signal is output to the lighting modules within the second alarm range on both sides of the visibility area corresponding to the Level 2 warning level; and a Level 3 alarm signal is output to the lighting modules within the third alarm range on both sides of the visibility area corresponding to the Level 3 warning level.

[0062] The comprehensive alarm strategy also includes a rainfall alarm setting sub-strategy, which includes: when the acquired ambient rainfall is greater than or equal to the first rainfall threshold, the acquired time point is set as the rainfall statistics start point, and the ambient rainfall is accumulated from the rainfall statistics start point to obtain the real-time accumulated rainfall.

[0063] The real-time acquired ambient rainfall and real-time accumulated rainfall are used to calculate the rainfall level reference value using the rainfall level calculation formula; the rainfall level calculation formula is configured as follows: Where Cjy is the rainfall level reference value, Jys is the real-time acquired ambient rainfall, JyL is the real-time accumulated rainfall, d1 is the real-time rainfall warning weight, d2 is the accumulated rainfall warning weight, d1+d2=1, and both d1 and d2 are greater than zero; in specific settings, d1 is greater than d2 because real-time rainfall has a significant impact on driving visibility, while the existing road drainage is relatively good, and the impact of accumulated rainfall is small. d1 is set to 0.95, and d2 is set to 0.05; the real-time acquired ambient rainfall is acquired at one-hour intervals, and the real-time accumulated rainfall is acquired at 24-hour intervals.

[0064] When the rainfall level reference value is greater than or equal to the first rainfall reference threshold, it is classified as Level 1 rainfall; when the rainfall level reference value is greater than or equal to the second rainfall reference threshold and less than the first rainfall reference threshold, it is classified as Level 2 rainfall; when the rainfall level reference value is less than the second rainfall reference threshold, it is classified as Level 3 rainfall; specifically, the first rainfall reference threshold is 10; the second rainfall reference threshold is 5.

[0065] The first-level rainfall level, the second-level rainfall level, and the third-level rainfall level are sent to the alarm unit of the lighting module.

[0066] The comprehensive alarm strategy also includes a snowfall alarm setting sub-strategy, which includes: when the acquired ambient snowfall is greater than or equal to the first snowfall threshold, the time point of acquisition is set as the snowfall statistics start point, and the ambient snowfall is accumulated from the snowfall statistics start point to obtain the real-time accumulated snowfall.

[0067] The real-time environmental snowfall and real-time cumulative snowfall are used to calculate the snowfall level reference value using the snowfall level calculation formula; the snowfall level calculation formula is configured as follows: Where Cjx is the reference value for snowfall level, Jxs is the real-time acquired ambient snowfall, JxL is the real-time accumulated snowfall, e1 is the real-time snowfall warning weight, e2 is the accumulated snowfall warning weight, e1+e2=1, and both e1 and e2 are greater than zero; in specific settings, d2 is greater than d1 because accumulated rainfall has a significant impact on road surfaces, e1 is set to 0.1, and e2 is set to 0.9; the real-time acquired ambient snowfall is acquired at one-hour intervals, and the real-time accumulated snowfall is acquired at 24-hour intervals.

[0068] When the snowfall level reference value is greater than or equal to the first snowfall reference threshold, it is classified as Level 1 snowfall; when the snowfall level reference value is greater than or equal to the second snowfall reference threshold but less than the first snowfall reference threshold, it is classified as Level 2 snowfall; when the snowfall level reference value is less than the second snowfall reference threshold, it is classified as Level 3 snowfall. In specific settings, the snowfall level standards in the existing weather system can be referenced, with the first snowfall reference threshold set to 1 and the second snowfall reference threshold set to 0.5.

[0069] The first-level snowfall level, the second-level snowfall level, and the third-level snowfall level are sent to the alarm unit of the lighting module.

[0070] The alarm unit is used to output alarm information within the alarm range. The alarm unit includes an alarm display device and is configured with a visibility alarm strategy. The visibility alarm strategy includes setting a first speed limit, a second speed limit, and a third speed limit for the first, second, and third level alarm signals, respectively; the first speed limit is 20 km / h, the second speed limit is 40 km / h, and the third speed limit is 60 km / h.

[0071] The alarm unit displays first information on the alarm display devices within the first alarm range on both sides of the visibility area corresponding to the Level 1 warning level; displays second information on the alarm display devices within the second alarm range on both sides of the visibility area corresponding to the Level 2 warning level; and displays third information on the alarm display devices within the third alarm range on both sides of the visibility area corresponding to the Level 3 warning level. The alarm unit is also equipped with a rain and snow alarm strategy, which includes setting first speed limit information, second speed limit information, and third speed limit information for Level 1, Level 2, and Level 3 rainfall levels, respectively.

[0072] First, second, and third speed limits are set for Level 1, Level 2, and Level 3 snowfall, respectively.

[0073] The alarm display device displays the corresponding first speed limit information, second speed limit information, and third speed limit information.

[0074] Working principle: The system acquires environmental visibility, rainfall, and snowfall data through an environmental monitoring unit. This data is then processed to obtain monitoring results. Based on these results, key areas along the distribution path are marked, allowing for the division of areas with different visibility levels. The monitoring results are then categorized into warning levels, and alarm ranges are set for key areas based on these levels. These alarm ranges are then output to the alarm unit. By incorporating the severity of the collected environmental data into the alarm data, the accuracy of alarm judgment is further improved. Finally, the alarm unit outputs alarm information within the alarm range.
