accordingly, step S12 in fig. 1 includes the following steps:
step S121: and when the definition is less than the preset definition, determining that the road surface needs to be maintained.
Generally, signs for representing left-turn, right-turn, bus-only lane and non-motor-vehicle-only lane are arranged on the road surface of the road to prompt a driver of the vehicle to drive or turn in the proper lane, and lane marks and sidewalk marks so as to distinguish the areas where the vehicle runs and pedestrians walk. The signs and markings are painted with colored paints that fade over time or are affected by pedestrian traffic as a result of rolling. If this sign and marking when unclear or incomplete, can influence the normal driving of vehicle, perhaps influence the pedestrian and walk at suitable position to lead to the traffic accident to take place, consequently, when sign on the road surface is unclear with the marking, need the maintenance personnel to maintain this road surface, with the definition of guaranteeing sign and marking, be convenient for indicate the driver of vehicle and pedestrian remove in suitable region.
In the embodiment of the present disclosure, the road information collected by the street lamp includes the definition information of the mark and the marking on the road surface, and accordingly, the street lamp can collect the information of the mark and the marking through the collecting device arranged on the street lamp, wherein the collecting device may be a signal collecting device, or an image collecting device, as long as it can collect whether the mark and the marking are clear or not.
Taking the collecting device as a camera as an example, the street lamp controls the camera arranged above the street lamp to shoot an image containing the mark and the marked line, analyzes the mark and the marked line in the image, determines the definition of the mark and the marked line, compares the definition with a preset definition, when the definition is greater than or equal to the preset definition, the mark and the marked line which show the road surface can be clearly seen by a driver or a pedestrian of a vehicle, and further ensures that the vehicle and the pedestrian respectively drive, turn or walk in proper areas, and when the definition is less than the preset definition, the mark and the marked line on the road surface are not clear, so that the driver or the pedestrian of the vehicle can not easily see, therefore, the mark and the marked line can be determined to be maintained, namely the road surface needs to be maintained, wherein the preset definition is pre-stored in the street lamp by a management department, the larger the numerical value is, the higher the definition requirement on the marks and marked lines of the road surface is, the more the times of maintaining the road surface is, the smaller the numerical value is, the lower the definition requirement on the marks and marked lines of the road surface is, and the fewer the times of maintaining the road surface is.

Fig. 3 is another flowchart of a method for maintaining a road surface according to an embodiment of the disclosure. As shown in fig. 3, the road surface information includes: in the case of the information on the flatness of the road surface, step S11 in fig. 1 includes the steps of:
step S113: controlling a ground penetrating radar arranged at the bottom of the street lamp to transmit a plurality of detection signals and receive reflected signals corresponding to the detection signals;
step S114: determining a pavement thickness value corresponding to each detection signal according to the time difference between each detection signal and the reflection signal and the propagation speed of the detection signal, wherein each detection signal corresponds to one pavement thickness value;
accordingly, step S12 in fig. 1 includes the following steps:
step S122: determining the road surface thickness value with the largest occurrence frequency as a standard value in a plurality of road surface thickness values corresponding to the plurality of detection signals;
step S123: and determining that the road surface needs to be maintained when the difference value between the road surface thickness value and the standard value is larger than a preset threshold value in the plurality of road surface thickness values.
Ideally, the road surface is flat to ensure smooth driving of vehicles on the road surface, however, in practical applications, as the number of vehicles passing through the road surface increases, the road surface of the road will be damaged to different degrees, and the quality of the road surface is reduced. In addition, when the damage appears on the road surface, the smoothness on road surface receives the influence, and the vehicle jolts easily when going on this road surface, causes not good experience to personnel in the car, consequently, when the damage appears on road surface, needs maintenance personnel to maintain this road surface to guarantee the smoothness of road, the vehicle of being convenient for steadily goes on this road surface, avoids jolting.
In the embodiment of the present disclosure, the road information collected by the street lamp includes the flatness information of the road surface, and accordingly, the street lamp can collect the road flatness information through the collecting device arranged on the street lamp, wherein the collecting device may be a signal collecting device or an image collecting device, as long as it can collect whether the road surface is flat or not.
Taking the collecting device as a ground penetrating radar as an example, the street lamp controls the ground penetrating radar arranged at the bottom of the street lamp to transmit a plurality of detection signals, the detection signals are electromagnetic waves, the electromagnetic waves penetrate the road surface in a short time, after penetrating the road surface, a signal is reflected back aiming at each detection signal and is called as a reflected signal, the ground penetrating radar receives the reflected signal, the street lamp determines a time difference according to the transmitting time of each detection signal and the time of receiving each reflected signal, and then determines a road surface thickness value corresponding to each detection signal according to the time difference and the propagation speed of the electromagnetic waves, wherein the ground penetrating radar can transmit a plurality of detection signals at the same time, and correspondingly, by adopting the method, a plurality of road surface thickness values can be calculated.
In this embodiment, the thickness value with the largest number of occurrences among the plurality of road surface thickness values calculated for the plurality of detection signals may be determined as a standard thickness value of the road, which is referred to as a standard value for short and is used to indicate that the road surface in the region is flat and free of damage. When the road surface thickness value is larger than the standard value, the road surface is convex, when the road surface thickness value is smaller than the standard value, the road surface is concave, the vehicle is not utilized to stably run in the above two conditions, therefore, when the road surface thickness value with the difference value larger than the preset threshold value exists in the plurality of road surface thickness values, the road surface of the road is determined to be damaged, and the request information of road surface maintenance is sent to a terminal of a maintenance worker of the road surface.
The request information includes position information of the road surface to be maintained, and also includes information that the flatness of the road surface needs to be maintained, so that after the maintenance personnel receives the request information, the maintenance personnel can acquire specific tasks of the road surface that needs to be maintained, namely maintenance of the flatness of the road surface, besides acquiring the position of the road surface that needs to be maintained, and then the maintenance personnel can carry equipment needed for maintaining the flatness of the road surface to the position of the road surface.
For example, assuming that 10 detection signals are transmitted by the ground penetrating radar at the same time, the street lamp calculates the road surface thickness values of 10cm, 6cm, 8cm, 9cm, 6cm, 10cm and 10cm respectively according to the time difference of receiving the 10 reflection signals corresponding to the 10 detection signals and the propagation speed of the detection signals, and the preset threshold value is 3cm, the standard road surface thickness value of the road can be determined to be 10cm, and the difference value between 6cm and 10cm is 4cm and is greater than the preset threshold value by 3cm, so that the road surface is determined to need to be maintained, and the street lamp sends request information that the road surface is required to be maintained for the flatness of the road surface to a terminal of a maintenance worker of the road surface.
Alternatively, a standard road surface thickness value may be stored in the street lamp in advance, the plurality of calculated road surface thickness values are compared with the standard road surface thickness value, and when the plurality of calculated road surface thickness values are inconsistent with the standard road surface thickness value, it is indicated that the road surface is damaged, and it is determined that the road surface needs to be maintained.
Adopt above-mentioned technical scheme, the roughness of considering the road surface can receive the influence along with live time, do not utilize the steady traveling on this road surface of vehicle, consequently, detect the roughness on road surface, whether the thickness that also is detecting the road surface changes, and when the thickness on road surface changes, send the request information of road surface maintenance to maintainer's terminal, the maintainer of being convenient for can in time maintain the roughness on road surface, guarantee that vehicle and pedestrian move on this road steadily, promote the travelling comfort that personnel and pedestrian in the car removed.
Fig. 4 is another flowchart of a method for maintaining a road surface according to an embodiment of the disclosure. As shown in fig. 4, step S13 includes the steps of:
step S131: when the road surface needs to be maintained, counting a first time period when the traffic flow on the road surface is smaller than a preset traffic flow;
step S132: determining a second time period for maintaining the road surface according to the first time period and the working time period of the road surface maintenance personnel;
step S133: and sending the request information of the road maintenance in the second time period to the terminal of the road maintenance worker.
When carrying out the maintenance to the road surface, in order to guarantee the normal clear of maintenance work, avoid as far as possible because of the vehicle goes the problem that causes the maintenance to be interrupted, or cause the casualties to the maintenance personnel, and, in order to reduce because of the influence that the road surface maintenance was gone to the vehicle, in this disclosed embodiment, when determining that the road surface needs the maintenance, the street lamp can further detect out the vehicle information on this road surface, it is less than the first time quantum of predetermineeing the traffic flow to count out the traffic flow, wherein, first time quantum is the time quantum that the traffic flow is less than predetermineeing the traffic flow, also be in this time quantum, vehicle quantity on this road surface is less, almost no vehicle passes through, can not cause the interrupt of road surface maintenance, this first time quantum can include a plurality of time quantums: 10: in a time period of 00-11: 00, 15: in a time period of 00-16: 00, 22: and the time period is 00-24: 00, and the like. The preset traffic flow may be a numerical value that the management department stores in the street lamp in advance.
As mentioned above, the first time period is used to represent the time period when the traffic flow is less than the preset traffic flow, and the first time period may include the night time period, and under the normal condition, the road maintenance worker is in the off-duty rest state during the night time period, if the request message is sent to the terminal of the road maintenance worker during the time period, the normal rest of the road maintenance worker will be affected, therefore, in order to ensure that the request message for road maintenance is sent to the terminal of the road maintenance worker during the working time period, in the embodiment of the present disclosure, after the street lamp determines the first time period when the traffic flow is less than the preset traffic flow, the second time period for maintaining the road surface may be further determined according to the working time period of the road maintenance worker, wherein the second time period is one time period within the first time period, and the second time period is the working time period of the road maintenance worker, and after the second time period is determined, the street lamp sends the request information of the road maintenance in the second time period to the terminal of the road maintenance worker.

The memory 604 is used to store computer program instructions that, when executed by the processor 603, implement the method of roadway maintenance as provided by embodiments 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 road surface maintenance method provided by the embodiment of the disclosure due to the fact that the other components are not too hot 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.
