A garden night lighting control method and system

Abstract

This invention discloses a method and system for controlling nighttime lighting in a garden. The method involves acquiring historical pedestrian traffic flow data for each road within a garden area during nighttime hours, determining the road traffic flow level based on this data, and marking intersections between roads. When an intersection is between a road with a high traffic flow level and a road with a low traffic flow level, the method acquires monitoring video footage from monitoring devices on the low-traffic road that directly faces and covers the intersection area during the nighttime hours. The method analyzes the pedestrian movement direction in the acquired video footage; when pedestrians are detected moving towards the low-traffic road, the method acquires the existing lighting fixtures and their information on those fixtures. The existing lighting fixtures are then sorted according to their distance from the intersection, and the system controls the lighting fixture closest to the intersection to be turned on. This method conserves lighting resources and reduces pedestrian traffic on roads with high traffic flow levels.

Description

Technical Field

[0001] The present invention relates to the technical field of garden lighting control, and in particular to a garden night lighting control method and system. Background Art

[0002] In a garden, many lamps are usually arranged according to the garden design. These lamps can not only be used as basic lighting, but also can be used in some scenes to cooperate with the reflection and shielding of plants, and set contour lights, buried lights, spotlights, etc. in combination with the characteristics of plants and bushes to create a sense of atmosphere in the garden at night and bring ornamental value to the garden landscape at night. However, in most cases, the biggest role of lamps in the garden is still lighting. The illumination areas of these lamps overlap with each other, and people rarely pass through some narrow paths at night for safety reasons. Therefore, the redundant lamps set up will cause a waste of lighting energy. Summary of the invention

[0003] The purpose of the present invention is to provide a garden night lighting control method and system. By using monitoring equipment, the movement direction of pedestrians at the intersection of a road with a high road flow level and a road with a low road level is analyzed. When it is detected that pedestrians have a tendency to move towards a road with a low road level, the lamps are controlled to light up to remind pedestrians that the road is passable, thereby saving lighting resources and reducing the flow of people on roads with high road flow levels.

[0004] To achieve the above objectives, this application provides the following solutions:

[0005] In a first aspect, the present application provides a method for controlling nighttime lighting in a garden, which specifically comprises the following steps:

[0006] S1. Obtain the historical passenger flow of each road in the garden area during the night time period, and determine the road flow level of the road according to the historical passenger flow, where the road flow level includes high and low;

[0007] S2, marking the intersection area between the roads, and determining the road flow level of the road corresponding to the intersection area;

[0008] S3. When the intersection area is the intersection of a road with a high road flow level and a road with a low road level, obtain monitoring video of the monitoring equipment on the road with a low road level, whose monitoring range is directly opposite the intersection and covers the intersection area, during the night time period;

[0009] S4, analyzing the direction of the pedestrian in the monitoring video obtained in step S3, and when it is detected that the pedestrian is moving towards a road with a low road grade, obtaining the lamps installed on the road with the low road grade and the corresponding lamp information;

[0010] S5, sorting the deployed lamps according to the distance from the intersection, and controlling the lamps at the intersection to turn on. In some specific implementation schemes, the specific process of determining the road flow level of the current road in step S1 is:

[0011] S11, recording the historical pedestrian flow change curves of each road in the garden area during the night time period of each week and each day, and storing the historical pedestrian flow change curves of each road during the night time period of each week and each day and the corresponding day of the week respectively;

[0012] S12. Get the day of the week where the current time is, call the historical pedestrian flow change curve of the corresponding day of the week, when the peak value and the trough value of the historical pedestrian flow change curve exceed the first preset threshold, the road flow level of the current road is high, when the peak value and the trough value of the historical pedestrian flow change curve are lower than the first preset threshold, the current road flow level is low.

[0013] In some specific implementation schemes, if the road traffic level of the current road is high, the night time period is divided into a peak time period and a low-peak time period according to the slope change rate of the historical passenger flow change curve. The night time period is the time period between sunset time of the day and sunrise time of the next day.

[0014] In some specific embodiments, the steps are further included:

[0015] The area where the road with a high road grade is located is segmented after removing the intersection area according to whether there is a focus area, and the road is divided into a first area where the focus area is located and a second area where the focus area is not located; wherein the focus area includes the area where the monitoring equipment is located, the area near the water or the steep slope step area;

[0016] The lamps arranged in the first area are controlled according to the first lighting control strategy, and the lamps arranged in the second area are controlled according to the second lighting control strategy.

[0017] In some specific embodiments, the method for controlling the lights on the second area of ​​the road is:

[0018] S01. Determine the time period at the current moment. If the current moment is in the peak time period, select the lamp with the largest illumination range from the lamps at the same installation position according to the installation position and illumination range of the lamps and save them as lighting lamps. Select the lighting lamps according to the illumination range, and control the lighting lamps that can cover the second area to be turned on for a long time during the peak time period.

[0019] S02. If the current moment is in the off-peak time period, select the trigger-type lamps from the installed lamps, select the lighting lamps with the largest illumination range from the trigger-type lamps in the same installation position, and control the lighting lamps to be triggered and started according to their trigger types during the off-peak time period.

[0020] In some specific implementation schemes, the lamp information includes the installation location, illumination range and type of the lamp. The lamp types include light-sensitive type and trigger type. If the road traffic level of the current road is low, the lamps on the road with the low road traffic level are controlled to be triggered and started according to their trigger type.

[0021] In a second aspect, the present application provides a garden night lighting control system, comprising:

[0022] A traffic statistics module is used to obtain the historical passenger flow of each road in the garden area during the night time period, and determine the road traffic level of the road according to the historical passenger flow, and the road traffic level includes high and low;

[0023] The intersection control module marks the intersection area between the roads and determines the road flow level of the road corresponding to the intersection area;

[0024] A pedestrian analysis module is used to obtain monitoring videos of monitoring equipment on a road with a low road grade and whose monitoring range is directly opposite to the intersection and covers the intersection area during the night time period when the intersection area is the intersection of a road with a high road flow grade and a road with a low road grade, analyze the direction of pedestrian movement in the obtained monitoring video, and obtain the lamps installed on the road with a low road grade and the corresponding lamp information when it is detected that the direction of pedestrian movement is toward the road with a low road grade;

[0025] The control module sorts the deployed lamps according to the distance from the intersection and controls the lamps at the intersection to turn on.

[0026] The inventive concept of this application is:

[0027] In existing gardens, multiple lamps are installed in the garden landscape, and each lamp illuminates a part of the garden landscape. The control method of each lamp is generally based on its trigger type. For example, light-sensitive lamps automatically turn on the lamp when the ambient brightness is lower than the preset brightness, and triggered lamps are triggered when pedestrians pass by. The control of these lamps is basically automatic according to the characteristics of the lamps themselves. From the perspective of lighting, when the lights of surrounding buildings or traffic roads are bright enough, many lights in the garden are redundantly designed, resulting in a waste of electricity.

[0028] In view of this, this application takes into account that pedestrians in the garden at night generally walk in the garden in a concentrated period of time, and people tend to walk on the main roads. Therefore, the flow of people on these main roads is very large, while some remote roads or narrow branches are not safe at night and are easy to get lost, so the flow of people is small. Therefore, the flow level of the road can be calibrated according to the historical flow of people. On the other hand, some locations on the road are close to some more dangerous areas such as steps, near water sources, or some monitoring equipment areas that require lighting equipment all the time. Therefore, the lighting equipment in these areas on the road needs to be set to long-term lighting.

[0029] Therefore, this application first classifies roads according to historical pedestrian flow, so that it can be known which roads are sections where pedestrians often pass by, and the road grade of the road is set as high, indicating that the road is a trunk road, and which sections are rarely visited, and the road grade of the road is set as low, indicating that the road is a branch road. For roads with few people, the lights are generally closed, and only trigger-type lamps are turned on. This kind of lamp will only illuminate when pedestrians approach. This will cause a problem. If there is no light on the road, pedestrians will not approach the road, so the trigger-type lamps cannot be lit. Therefore, video analysis can be used to analyze whether the pedestrian has a tendency to move on the road with few people. If so, the lamp closest to the road is lit to inform the user that the road is illuminated and passable. In addition, for roads with large pedestrian flow, the road is segmented by judging whether there is an area on the road that needs long-term lighting. In this way, the type and road flow level of each area where each road is located in the garden can be known. Time-sharing and segmented control based on the type and road flow level of each area where each road is located can reduce the waste of lamps. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] Example 1

[0039] like Figure 1 As shown, this embodiment provides a garden night lighting control method, which specifically includes the following steps:

[0040] S1. Obtain the historical passenger flow of each road in the garden area during the night time period, and determine the road flow level of the road according to the historical passenger flow, where the road flow level includes high and low;

[0041] The specific process of determining the road flow level of the road in step S1 is as follows:

[0042] S11, recording the historical pedestrian flow change curves of each road in the garden area during the night time period of each week and each day, and storing the historical pedestrian flow change curves of each road during the night time period of each week and each day and the corresponding day of the week respectively;

[0043] S12, obtain the day of the week where the current time is located, call the historical pedestrian flow change curve corresponding to the day of the week, when the peak value and trough value of the historical pedestrian flow change curve exceed the first preset threshold value, the road flow level of the current road is high, when the peak value and trough value of the historical pedestrian flow change curve are lower than the first preset threshold value, the current road flow level is low. Generally, the number of people in a garden is 0 at the least, and the maximum is when people gather to travel. When the peak and trough of the pedestrian flow change differ greatly, it proves that the pedestrian flow on the road is large, and it is a road section that people often pass by, and when the peak and trough differ little, it proves that the number of pedestrians passing by the road is small.

[0044] If the current road traffic level is high, the night time period is divided into peak time period and low peak time period according to the slope change rate of the historical pedestrian flow change curve. The night time period is the time period between sunset of the day and sunrise of the next day. The rule of the pedestrian flow curve in the garden is generally from 0 to the peak value, and then gradually changes from the peak value to 0. The most obvious change period can be defined as the peak time period, and the time period corresponding to the relatively gentle curve can be defined as the low peak time period. Alternatively, the peak period can be defined as the time from sunset to midnight of the day, which corresponds to the time when people travel at night, and the low peak period is between midnight of the day and the second sunrise time.

[0045] For gardens at night, it is generally the residents who live near the gardens who walk their dogs or go for a stroll in the gardens. In this way, the changes in the flow of people in the same time period each week are not much different. Therefore, the historical flow data of the previous week can be used to predict the current flow of people corresponding to the time of last week. For example, assuming that the current time is Saturday, the historical flow of people on Saturday last week can be obtained to set the lighting control strategy, and the historical flow of people on Saturday next week can be updated every week based on the flow of people counted on Saturday this week.

[0046] S2. Mark the intersection area between each road and determine the road flow level of the road corresponding to the intersection area; the lamp information includes the installation position, illumination range and type of the lamp. The lamp type includes photosensitive type and trigger type. If the road flow level of the current road is low, the lamps on the road with low road flow level are controlled to be normally closed, and for lamps of triggered type (i.e., triggered by pedestrians approaching), they are triggered and started according to their trigger type.

[0047] S3. When the intersection area is the intersection of a road with a high road flow level and a road with a low road level, obtain monitoring video of a monitoring device on the road with a low road level whose monitoring range is directly opposite the intersection and covers the intersection area during the night time period;

[0048] S4, analyzing the direction of the pedestrian in the monitoring video obtained in step S3, and when it is detected that the pedestrian is moving towards a road with a low road grade, obtaining the lamps installed on the road with the low road grade and the corresponding lamp information;

[0049] S5. Sort the deployed lamps according to the distance from the intersection, and control the lamps at the intersection to turn on.

[0050] Also includes the steps:

[0051] S6. After removing the intersection area, the area where the road with a high road grade is located is segmented according to whether there is a focus area, and the road is divided into a first area where the focus area is located and a second area where the focus area is not located; wherein the focus area includes an area where the monitoring equipment is located, an area near water, or an area of ​​steep slope steps;

[0052] S7. Control the lamps arranged in the first area according to the first lighting control strategy, and control the lamps arranged in the second area according to the second lighting control strategy.

[0053] S71. The lamp information includes the installation location, illumination range and type of the lamp. The lamp type includes light-sensitive type and trigger type. The control process of the first lighting control strategy is:

[0054] According to the installation positions of the lamps, the photosensitive lamps installed in the first area of ​​the road are obtained. According to the illumination range of each installed photosensitive lamp, only the photosensitive lamp with the installation position closest to the area of ​​interest and the largest illumination range is used as the lighting equipment, and the lighting equipment is controlled to illuminate the area of ​​interest during the entire night period.

[0055] The area of ​​concern includes the area where the monitoring equipment is located, the area near water or the area of ​​steep slope steps; according to the installation position of the lamp, the photosensitive lamps installed in the first area of ​​the current road are obtained, and according to the installation height, brightness and illumination range of each installed photosensitive lamp, only the photosensitive lamp with the installation position closest to the area of ​​concern and the largest illumination range is used as the lighting equipment, and the range of the area of ​​concern is obtained for comparison with the illumination range. If the illumination range of the lamp is smaller than the range of the area of ​​concern, the lamp that is next closest to the area of ​​concern and whose illumination range complements the illumination range of the above-mentioned nearest photosensitive lamp is selected from the lamps installed in the area of ​​concern as a supplement to the lighting equipment, and the lighting equipment is controlled to illuminate the area of ​​concern throughout the night time period. The lamps in the first area are required to be always on to illuminate the branch for a long time, especially in the area where the monitoring equipment is located. It is necessary to illuminate the area within the monitoring range of the monitoring equipment as much as possible. Therefore, it is necessary to select the light-sensitive lamp that is closest to the monitoring equipment in the monitoring equipment installation area, provides the maximum brightness for the monitoring equipment, and has the largest illumination range as the lighting equipment of the monitoring equipment. Here, if the illumination range of the selected lamp is smaller than the monitoring range of the monitoring equipment, other lamps with complementary illumination ranges can be selected to fill the monitoring range, so as to fully cover the monitoring range. For the area near the water, it is necessary to select the lamp with the highest brightness as much as possible to illuminate the area near the water, or set up sensors in the area near the water. When pedestrians are detected approaching, the lamps in the area near the water are controlled to flash to remind people to avoid accidentally stepping in. Similarly, step-type lamps are generally installed under the stairs or for road lighting. At this time, light-sensitive lamps with the largest illumination range can be selected as lighting equipment.

[0056] S72. For a road that people often pass by, if the current road traffic level is high, the method for controlling the lights in the second area of ​​the road is:

[0057] S01. Determine the time period at the current moment. If the current moment is in the peak time period, select the lamp with the largest illumination range from the lamps at the same installation position according to the installation position and illumination range of the lamps and save them as lighting lamps. Select the lighting lamps according to the illumination range, and control the lighting lamps that can cover the second area to be turned on for a long time during the peak time period.

[0058] S02. If the current moment is in the off-peak time period, select the trigger-type lamps from the installed lamps, select the lighting lamps with the largest illumination range from the trigger-type lamps in the same installation position, and control the lighting lamps to be triggered and started according to their trigger types during the off-peak time period.

[0059] It is understandable that in this application, each road in the garden is first divided according to the density of pedestrian flow, divided into high-flow roads and low-flow roads, and then the lighting control strategy for each road in each time period is determined based on the flow of people, and the lamps installed on the road are controlled in a time-sharing manner. Then, some key areas of concern on each road need to be illuminated for a long time, so as to realize the segmented control of the lamps installed on the road. Specifically, when the current road is a high-flow road, first determine whether there is an area of ​​concern on the road. If so, the area of ​​concern is controlled to be illuminated for a long time, and other areas are controlled in a time-sharing and segmented manner, that is, when the current moment belongs to the peak time period, the lamps installed on the road are controlled according to the principle of minimum power consumption, and when the current moment belongs to the low-peak time period, they are controlled in a way of triggering the lighting.

[0060] When the current road is a low-traffic road, the lamps are generally controlled to be closed, but pedestrians have no way of knowing that the road is passable. Therefore, the frontal photo of the pedestrian captured by the surveillance video facing the intersection can be used to determine whether the pedestrian has a tendency to move toward the road. If so, the lamp on the road closest to the intersection will light up to remind the pedestrian that the road is passable. When the pedestrian enters the road, the lamp can be controlled to light up according to the pedestrian trigger, or the illumination range of the lamps on the road can be obtained, the lamps can be screened, and the lamps whose illumination range can cover the road area can be controlled to light up in advance.

[0061] like Figure 2As shown, the garden area generally includes multiple roads, and lamps are installed on both sides of each road, such as photosensitive lamps 2 and trigger lamps 1. If there is a monitoring device on the road, the location of the monitoring device and the range that the monitoring device can monitor are divided into the area where the monitoring device is located. For the road, the area range of the road is the area on both sides of the road. Therefore, the road can be segmented according to the area where the monitoring device is located. The monitoring device area is the first area, and other locations are the second area. For the lamps in the first area, it is necessary to select lamps 2 that meet the lighting conditions of the monitoring equipment, and are long-term lighting and can automatically illuminate when the ambient brightness is lower than the brightness required by the monitoring equipment; and for the lamps in the second area, it is only necessary to select lamps whose illumination range can cover the branch road, and the trigger lamps 2 can be controlled for long-term lighting during peak hours, and the trigger lamps can be illuminated in a triggered manner during off-peak hours. For the lamps at the intersection, when the intersection area is the intersection of a road with a high road flow level and a road with a low road level, since the lamps on the road with a low road level are often closed, it is easy to give pedestrians a misunderstanding that the road is impassable. In fact, the lamps on the road need to be triggered by pedestrians to light up. Therefore, with the help of monitoring equipment, and the monitoring equipment needs to face the intersection, and the shooting range can cover the intersection area. In this way, with the help of the lights on the road with a high traffic level in the intersection area, the front of the pedestrian can be clearly photographed. By judging whether the front of the pedestrian faces the road with a low road level, it is judged whether he has a tendency to move toward the road, and the direction of movement of the pedestrian in the intersection area is analyzed. When it is detected that the pedestrian has a tendency to move toward the road, the lamps are controlled to light up to remind the pedestrian that the road is passable. If the intersection area is the intersection of a road with a high road flow level and a road with a high road level, all lamps in the intersection area are controlled, the illumination range of the lamps is screened, and the lamps whose illumination range can cover the intersection area are controlled to light up.
