Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In order to avoid electric energy waste of the street lamp and improve the illumination service capability of the street lamp on pedestrians and vehicles as much as possible, the embodiment of the disclosure provides a method, a device, the street lamp and a readable storage medium for controlling the street lamp.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling a street lamp according to an embodiment of the disclosure. As shown in fig. 1, the method for controlling a street lamp provided by the embodiment of the present disclosure is applied to a street lamp, and includes the following steps:
step S11: acquiring the starting condition of a lamp of a vehicle passing through the lower part of the street lamp from a first preset moment;
step S12: determining the lighting time of the street lamp according to the starting condition of the vehicle lamp;
step S13: and controlling the street lamp to be lighted according to the lighting time of the street lamp.
In general, when the weather is good or the ambient brightness is high, the sight line of the driver is good, at this time, the driver can clearly observe the condition of other vehicles or pedestrians around the vehicle without the illumination of other lamps (lamps, street lamps and the like), when the weather is bad (for example, cloudy days, foggy days and the like) or the ambient brightness is low, the ambient brightness around the vehicle is low, the sight line of the driver is affected, the condition of other vehicles or pedestrians around the vehicle cannot be clearly observed, at this time, the driver can turn on the lamps of the vehicle to illuminate the road where the vehicle runs, and therefore, the current weather or the ambient brightness can be reflected by the turn-on condition of the lamps of the vehicle, and whether the driver of the vehicle needs other lamps to assist illumination or not can be reflected. In the embodiment of the disclosure, the street lamp can determine the current weather or the ambient brightness according to the turning-on condition of the lamp of the vehicle passing through the lower part of the street lamp, so as to determine the lighting time of the street lamp.
The street lamp in the embodiment of the present disclosure is provided with a signal acquisition device or an image acquisition device capable of acquiring a vehicle passing through the lower portion of the street lamp, so that when the vehicle passes through the lower portion of the street lamp, the street lamp can acquire the vehicle, specifically: when the vehicle runs into the collection area covered by the signal collection device or the image collection device, the signal collection device or the image collection device can collect the vehicle, wherein the signal collection unit can be a radar probe and any equipment with signal transmission and signal reception functions, and the image collection device can be a camera, a monitor and the like.
In an example, the signal acquisition device and the image acquisition device can be used separately to acquire vehicles passing below the street lamp, or the signal acquisition device and the image acquisition device can be used together to acquire vehicles passing below the street lamp, under the condition that the signal acquisition device and the image acquisition device act together to acquire vehicles, the signal acquisition unit can determine whether a vehicle enters an acquisition area covered by the signal acquisition device through real-time transmission and reception of signals, and when it is determined that a vehicle enters the area, the street lamp can control the image acquisition device arranged on the street lamp to be adjusted from a dormant state to a working state so as to acquire image information of the vehicle, and acquire a car lamp starting condition of the vehicle from the image information of the vehicle. It should be noted that, in the embodiment of the present disclosure, the implementation of collecting the vehicle by the street lamp is not limited.
Therefore, in step S11, the street lamp acquires the turn-on condition of the lamps of the vehicles passing under the street lamp from the first preset time, for example, the street lamp may obtain whether the lamp of the vehicle is in an on state according to the information of the vehicle collected by at least one of the signal collecting device and the image collecting device, wherein the first preset time can be preset in the street lamp by the traffic management department, the later the first preset time is, the later the street lamp is turned on, the less the street lamp consumes electric energy, however, the later the time for providing the illumination service for the vehicle is, the less safe the driver drives, the earlier the first preset time is, the earlier the street lamp is turned on, can meet the requirement that the driver of the vehicle needs the street lamp for auxiliary illumination in time, is beneficial to the safe driving of the vehicle, however, the more electric energy the street lamp consumes, so the traffic control department can set the first preset time according to the actual demand and different environmental brightness changes in different seasons.
For example, in summer, the first preset time may be 17:00 due to the fact that the weather becomes dark later, in winter, the first preset time may be 16:00 due to the fact that the weather becomes dark earlier, or, in consideration of the fact that the street lamp is required to be lit in a key point when the weather is dark in cloudy days, that is, in daytime, the street lamp is required to be lit in cloudy days, the first preset time may be 00:00, so as to detect whether the street lamp is required to be turned on in real time.
Next, in step S12, the street lamp determines the lighting time of the street lamp according to the turning-on state of the lamp of the vehicle. As described above, the vehicle lamp in the on state can reflect the current weather or the lower ambient brightness, and the driver of the vehicle may need the auxiliary lighting of the street lamp, so that the street lamp can know that the current weather or the lower ambient brightness, and the driver of the vehicle may need the auxiliary lighting of the street lamp according to the on condition of the vehicle lamp of the vehicle, and further determine the proper lighting time of the street lamp. And finally, after the proper lighting time of the street lamp is determined, controlling the street lamp to be lighted so as to meet the requirement that a driver of the vehicle needs the street lamp for auxiliary lighting.
The method for controlling the street lamp provided by the embodiment of the disclosure is applied to the street lamp, and firstly, the street lamp obtains the lamp turning-on condition of a vehicle passing through the lower part of the street lamp from a first preset time, then, the proper turning-on time of the street lamp is determined according to the vehicle turning-on condition, and finally, the street lamp is controlled to be turned on according to the proper turning-on time, so that the turning-on time of the street lamp is not fixed, but is determined according to the lamp turning-on condition of the vehicle actually passing through the lower part of the street lamp, the flexibility of the turning-on time of the street lamp is improved, meanwhile, when a driver of the vehicle needs the street lamp auxiliary lighting, the street lamp is turned on, so that the lighting service capability of the street lamp to the vehicle is improved, and in addition, when the driver of the vehicle does not need the street lamp auxiliary lighting, the street lamp is in the off state, thereby avoiding the waste of the electric energy of the street lamp, the service life of the street lamp is prolonged.
Optionally, please refer to fig. 2, fig. 2 is another flowchart of a method for controlling a street lamp according to an embodiment of the present disclosure. As shown in fig. 2, step S11 in fig. 1 includes the following steps:
step S111: counting a first total number of vehicles passing through the lower part of the street lamp from a first preset moment;
step S112: determining the number of vehicles passing through the lamps below the street lamps in an on state in the first total number of the vehicles;
accordingly, step S12 includes the steps of:
step S121: determining a first ratio of the number of vehicles with the lamps in the on state to the first total number;
step S122: and determining the time when the first ratio is greater than or equal to a first preset ratio as the lighting time of the street lamp.
In practical application, it is considered that there are a plurality of vehicles passing under the street lamp, lamps of some of the vehicles may be turned on, lamps of some of the vehicles may be turned off, and lamps of some of the vehicles may be turned on by a hand of a driver or forgotten to be turned off after the vehicle changes a lane, so as to determine whether the street lamp is turned on and when the street lamp is turned on, and in the embodiment of the disclosure, whether the street lamp is turned on and the time when the street lamp is turned on may be determined according to a relationship between a ratio of the number of the vehicles passing under the street lamp in the turned on state to the total number of the vehicles passing under the street lamp and a first preset ratio. The first preset ratio may be preset by a traffic management department and may be used to represent the lighting time of the street lamp, and the larger the first preset ratio is, the more the number of the vehicles of the vehicle lamp in the on state is, the later the lighting time of the street lamp is, the smaller the first preset ratio is, the smaller the number of the vehicles of the vehicle lamp in the on state is, the earlier the lighting time of the street lamp is, and for example, the first preset ratio may be 50%, 60%, and the like.
Therefore, when the street lamp acquires the turning-on condition of the lamp of the vehicle passing below the street lamp, one possible implementation mode is as follows: counting a first total number of vehicles passing through the lower portion of the street lamp from a first preset moment, and determining the number of the vehicles with the lamps in the on state in the first total number of the vehicles. When the number of vehicles with the lamps in the on state is large, the probability that the lamps are turned on by the hands of a driver by mistake or the lamps are forgotten to be turned off after the vehicles change lanes is low, at the moment, the reason that the lamps are turned on by the driver can be determined to be that the ambient brightness is low, the sight of the driver of the vehicle is poor, and the driver needs the assistance of other lamps, so that the street lamp can be turned on.
Correspondingly, the implementation mode of determining the lighting time of the street lamp according to the turning-on condition of the lamp of the vehicle by the street lamp is as follows: according to the determined number of the vehicles with the lamps in the opening state and the counted first total number of the vehicles passing through the lower portion of the street lamp from the first preset time, a first ratio of the number of the vehicles with the lamps in the opening state to the first total number can be determined, the first ratio is compared with the first preset ratio, and when the first ratio is larger than or equal to the first preset ratio, the time when the first ratio is larger than or equal to the first preset ratio is determined as the lighting time of the street lamp.
As described above, when the number of the vehicles with the lamps in the lighting state is large, it indicates that the ambient brightness is low, the line of sight of the driver of the vehicle is poor, and more drivers need to light the streetlamps for auxiliary lighting, so that when the first ratio is greater than or equal to the first preset ratio, the streetlamps are lit, that is, the streetlamps are lit at a time when the first ratio is greater than or equal to the first preset ratio.
Illustratively, the first preset time is 17:00, the first preset ratio is 75%, the street lamp starts to count the first total number of vehicles passing through the street lamp in real time at the time of 17:00 and the number of vehicles with the lamps in the on state, the total number of vehicles is 20 at 17:10, wherein the number of vehicles with the lamps in the on state is 15, and therefore, the street lamp determines that the first ratio is 75% at 17:10, that is, at the time, the first ratio is equal to the first preset ratio, and therefore, 17:15 is determined as the time when the street lamp is on.
By adopting the technical scheme, the street lamp determines the ratio of the vehicles passing through the lower part of the street lamp in the opening state to the total number of the vehicles passing through the lower part of the street lamp in real time, compares the ratio with the first preset ratio, determines the time when the ratio is greater than or equal to the first preset ratio as the time when the street lamp is turned on, and then turns on the street lamp at the time, so that misjudgment of the turn-on time of the street lamp caused by the fact that an individual driver turns on the vehicle lamp by mistake can be avoided, the accuracy of the determined turn-on time of the street lamp can be ensured, the street lamp can be turned on at a proper time as far as possible, the waste of electric energy is not caused, and the safe driving of the driver is not influenced.
Optionally, please refer to fig. 3, fig. 3 is another flowchart of a method for controlling a street lamp according to an embodiment of the present disclosure. As shown in fig. 3, after step S13, the method further includes the steps of:
step S14: counting a second total number of vehicles passing through the lower part of the street lamp and the number of vehicles with the lamps in a closed state from a second preset moment;
step S15: when a second ratio of the number of the vehicles with the lamps in the off state to the second total number is greater than or equal to a second preset ratio, determining that the time when the second ratio is greater than or equal to the second preset ratio is the extinguishing time of the street lamp;
step S16: and controlling the street lamp to be extinguished according to the extinguishing time of the street lamp.
When the current weather or the ambient brightness can meet the condition that a driver clearly observes pedestrians or other vehicle states around the vehicle, the driver of the vehicle can turn off the vehicle lamp to reduce the power consumption of the vehicle as much as possible, and at the moment, the turn-off time of the street lamp can be determined according to the turn-off condition of the vehicle lamp.
In practical applications, considering that there are a plurality of vehicles passing under the street lamp, and there may be a situation that some of the vehicles are in an on state and some of the vehicles are in an off state, in the embodiment of the present disclosure, whether the street lamp is turned off and the time for turning off the street lamp may be determined according to a relationship between a ratio of the number of the vehicles passing under the street lamp in the off state to the total number of the vehicles passing under the street lamp and a second preset ratio.
The second preset ratio may be preset by a traffic management department and may be used to represent the time for turning off the street lamp, and the larger the second preset ratio is, the more the number of the vehicles of the street lamp in the off state is, the time for turning off the street lamp is later, and the smaller the second preset ratio is, the less the number of the vehicles of the street lamp in the off state is, the time for turning off the street lamp is earlier, for example, the second preset ratio may be 70%, 80%, and the like.
Specifically, the embodiment of determining the off time of the street lamp is as follows: and counting a second total number of vehicles passing below the street lamp and the number of the vehicles with the lamps in the off state by the street lamp from a second preset time, determining that the time when the second ratio is greater than or equal to the second preset ratio is the extinguishing time of the street lamp when the second ratio of the number of the vehicles with the lamps in the off state to the second total number is greater than or equal to the second preset ratio, and finally controlling the street lamp to be extinguished according to the extinguishing time.
The second preset time can be preset in the street lamp by the traffic management department, the later the second preset time is, the longer the street lamp is started, the longer the time for providing lighting service for the vehicle is, but the more the street lamp consumes, the earlier the second preset time is, the shorter the street lamp is started, the less the street lamp consumes, but the shorter the time for providing lighting service for the vehicle is, so that the traffic management department is not beneficial to safe driving of the vehicle, and the second preset time can be set according to actual needs and different environmental brightness changes in different seasons. For example, the second preset time may be 5:00 in summer since the time of weather lightening is earlier, and may be 7:00 in winter since the time of weather lightening is later, or may be 00:00 in consideration of weather lightening at any time due to fog scattering at any time in foggy days, so as to detect whether the street lamp needs to be extinguished in real time.
When the number of the vehicles with the vehicle lamps in the off state is large, it is indicated that the ambient brightness is high, the sight of the drivers of the vehicles is good, and the drivers do not need to light the street lamps to assist in lighting, so that the street lamps are extinguished when the second ratio is greater than or equal to the second preset ratio, that is, the street lamps are extinguished at the moment when the second ratio is greater than or equal to the second preset ratio.
Illustratively, the second preset time is 4:00, the second preset ratio is 70%, the street lamp starts to count the second total number of vehicles passing through the street lamp in real time at the time of 4:00 and the number of vehicles with the lamps in the off state, and the total number of vehicles is 10 at 5:00, wherein the number of vehicles with the lamps in the off state is 7, so that the street lamp determines that the second ratio is 70% at 5:00, that is, at the time, the second ratio is equal to the second preset ratio, so that 5:00 is determined as the time when the street lamp is turned off.
Therefore, by adopting the technical scheme, the street lamp determines the ratio of the vehicles passing through the lower part of the street lamp in the closed state to the total number of the vehicles passing through the lower part of the street lamp in real time, compares the ratio with the second preset ratio, and determines the time when the ratio is greater than or equal to the second preset ratio as the time when the street lamp is turned off, so as to turn off the street lamp at the time.
Optionally, please refer to fig. 4, fig. 4 is another flowchart of a method for controlling a street lamp according to an embodiment of the present disclosure. As shown in fig. 4, after step S13, the method further includes the steps of:
step S17: when the traffic flow density below the street lamp is greater than the preset density, adjusting the brightness value of the street lamp to be a first brightness value;
step S18: and when the traffic flow density below the street lamp is not greater than the preset density, adjusting the brightness value of the street lamp to be a second brightness value, wherein the first brightness value is greater than the second brightness value.
Generally, when the total number of vehicles on the road is large, the probability of collision of the vehicles is high, and therefore, a driver of the vehicle is required to clearly observe the driving states of other vehicles around the vehicle when driving the vehicle, that is, the requirement of the driver of the vehicle on the ambient brightness is high, and further the street lamp is required to provide high brightness.
In the embodiment of the disclosure, after the street lamp is turned on, the street lamp may further determine a traffic flow density passing through a lower portion of the street lamp, when the traffic flow density is greater than a preset traffic flow density, it indicates that there are more vehicles on the road, and further, the luminance value of the street lamp needs to be adjusted to a first luminance value, when the traffic flow density is not greater than the preset traffic flow density, it indicates that there are fewer vehicles on the road, a driver of the vehicle does not have a high requirement for the environment luminance, and does not need to provide the street lamp with higher luminance, at this time, consumption of the street lamp on electric energy is reduced, and the luminance value of the street lamp may be adjusted to a second luminance value, where the first luminance value is greater than the second luminance value, and the first luminance value and the second luminance value are both pre-stored in the street lamp. Therefore, by adopting the technical scheme, after the street lamp is controlled to be lightened, the brightness of the street lamp can be further adjusted according to the traffic flow density below the street lamp, and the consumption of the street lamp on electric energy is reduced as much as possible on the premise of meeting the brightness required by a driver of a vehicle.

the first adjusting module is used for adjusting the brightness value of the street lamp to be a first brightness value when the traffic density below the street lamp is greater than the preset traffic density;
and the second adjusting module is used for adjusting the brightness value of the street lamp to be a second brightness value when the traffic flow density below the street lamp is not greater than the preset traffic flow density, and the first brightness value is greater than the second brightness value.
With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
Based on the same inventive concept, the embodiment of the disclosure also provides a street lamp. Fig. 6 is a schematic view of a street lamp provided by the embodiment of the disclosure. As shown in fig. 6, a street lamp 600 provided by the embodiment of the present disclosure includes: a light source 601, a heat sink assembly 602, a processor 603, and a memory 604.
The heat dissipation assembly 602 includes a thermal grease, a processor 603, a memory 604 and a light source 601 are disposed above the heat dissipation assembly 602, and the processor 603 is connected to the memory 604 and the light source 601 respectively. The memory 604 is used for storing computer program instructions which, when executed by the processor 603, implement a method of controlling a street lamp as provided by an embodiment of the present disclosure.
Because the processor 603, the memory 604 and the light source 601 are disposed above the heat dissipation assembly 602 in the street lamp 600, other components (for example, the processor 603, the memory 604 and the light source 601) in the street lamp 600 can be well dissipated through the heat dissipation assembly 602, and it is ensured as far as possible that the street lamp 600 cannot implement the method for controlling the street lamp provided by the embodiment of the present disclosure due to the fact that the temperature of the other components is too high due to poor heat dissipation, thereby ensuring as far as possible the intellectualization of the street lamp 600.
Optionally, the heat-conducting silicone grease included in the heat dissipation assembly 602 is prepared from a specific composition, where the specific composition includes silicone oil, a first filler, a second filler, and optionally an auxiliary agent, and based on 100 parts by weight of the silicone oil, the content of the first filler is 10 to 60 parts by weight, the content of the second filler is 50 to 150 parts by weight, and the content of the auxiliary agent is 0 to 20 parts by weight; the first filler comprises a metal heat conductor and a phase-change material, and the weight ratio of the metal heat conductor to the phase-change material is 1: (0.2 to 2.5); the second filler comprises carbon nanotubes and graphene, and the weight ratio of the carbon nanotubes to the graphene is 1: (1-20).
Preferably, the content of the first filler is 20 to 40 parts by weight, the content of the second filler is 80 to 120 parts by weight, and the content of the auxiliary agent is 0 to 10 parts by weight, based on 100 parts by weight of the silicone oil;
further preferably, in order to further improve the thermal conductivity of the thermally conductive silicone grease and reduce the thermal resistance value, R is 6.5 to 35.5 calculated by the following formula:
r ═ 0.656w (second filler) -1.581w (first filler) +0.11w (adjuvant),
wherein w (first filler) represents parts by weight of the first filler relative to 100 parts by weight of the silicone oil,
w (second filler) represents parts by weight of the second filler relative to 100 parts by weight of the silicone oil,
w (adjuvant) represents the parts by weight of adjuvant with respect to 100 parts by weight of silicone oil.
The heat-conducting silicone grease composition adopts the metal heat conductor and the phase-change material as the first filler, and compared with the traditional heat-conducting silicone grease which only adopts the metal heat conductor as the filler, the heat-conducting silicone grease composition can effectively improve the absorption rate of heat of a heat source and has the effects of quickly absorbing heat and transferring heat; meanwhile, the carbon nano tube and the graphene are used as second fillers, so that the heat conductivity coefficient is greatly improved, the compatibility with silicone oil is facilitated, and the quality and the performance of the specific composition are further improved.
The heat-conducting silicone grease prepared from the composition can effectively improve the heat-conducting and heat-radiating efficiency of the heat-radiating component 602. Due to the improvement of the heat dissipation efficiency, a good heat dissipation effect can be achieved by using the heat dissipation assembly 602 with a smaller volume, so that more space can be saved to facilitate the placement of the light source 601, the processor 603, the memory 604 and other assemblies, and the overall volume of the street lamp 600 is reduced. Especially when carrying out intelligent transformation to current street lamp, less volume's street lamp 600 can be installed in current old street lamp body, and need not to change whole street lamp holders, and the transformation cost is lower, efficiency is higher.
Based on the same inventive concept, the disclosed embodiments also provide a computer-readable storage medium, on which computer program instructions are stored, which when executed by a processor implement the steps of the method of controlling a street lamp provided by the disclosed embodiments. For example, the computer readable storage medium may be a ROM, a Random Access Memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.
The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various combinations that are possible in the present disclosure are not described again.
In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
