Therefore, in this embodiment, by constructing the traffic prediction model and inputting the traffic prediction model with the location information and the environmental information of the area where each set of intelligent lamp pole groups is located, the traffic distribution area of the illumination coverage area of each set of intelligent lamp pole groups in each unit period at night and the traffic class of the traffic distribution area can be predicted.
In this embodiment, when the traffic prediction model is constructed, training may be performed using sample data, where the sample data may obtain historical data from a relevant statistics department, city planning department, or tourist attraction management department; real-time people flow data can be acquired by using equipment such as cameras, infrared sensors, thermal imagers and the like which are installed in cities. These data typically record personnel number, density and flow direction; and some mobile applications and social media platforms may collect and share people's location information that may be used to infer people traffic. Secondly, the investigation of the field people flow can be carried out at specific places by dispatching investigators, and people flow conditions in different time periods can be recorded to be used as the supplement of sample data.
Step S30: based on the people flow distribution area and people flow level of each intelligent lamp pole group at each period of night, the brightness control instruction of each intelligent lamp pole group is generated.
In this embodiment, the traffic class includes: primary, secondary, and tertiary;
When the traffic class is one level, the traffic is larger in the period, the brightness control instruction of the intelligent lamp post is that the brightness of the intelligent lamp post is kept at the first preset brightness, and at the moment, the brightness of all the intelligent lamp posts in the area where the traffic is larger is always kept at the first preset brightness in the whole period;
When the traffic class is two-level, the traffic is sparse in the period, the appropriate reduction can be realized, the brightness control instruction of the intelligent lamp pole is that the brightness of the intelligent lamp pole is kept at a second preset brightness, and the first preset brightness is larger than the second preset brightness; the brightness of all intelligent lamp poles in the area is always kept at a second preset brightness in the whole period;
When the people flow rate level is three-level, the people flow rate in the period is less, no more people exist on the whole road, people can pass occasionally, and the brightness control instruction of the intelligent lamp post is that the brightness of the intelligent lamp post is kept at the third preset brightness, and the third preset brightness is smaller than the second preset brightness.
Specifically, when the brightness of the intelligent lamp posts is at a third preset brightness, the pedestrian sensors on the intelligent lamp posts monitor whether pedestrians exist on the road in real time; when the pedestrian sensor detects that pedestrians exist on the road, the brightness of the intelligent lamp post is increased from the third preset brightness to the second preset brightness, and after the second preset brightness of the intelligent lamp post is kept for a first time, the brightness is restored to the third preset brightness.
In this embodiment, when a pedestrian approaches a certain smart lamp post, the brightness of the smart lamp post is increased to a second preset brightness, and the third preset brightness may be that the lamp of the smart lamp post is in a turned-off state.
Step S40: the brightness control instructions of all intelligent lamp poles of each intelligent lamp pole group are sent to the main control units of the main lamps of each group through the 5G base station, the main control units of the main lamps of each group send the brightness control instructions of the intelligent lamp poles of the auxiliary lamps to the main control units of the corresponding auxiliary lamps respectively, and the brightness of the lamps of all intelligent lamp poles is adjusted by all the main control units of each group based on the brightness control instructions of all the intelligent lamp poles of each group.
In the embodiment, a traffic distribution area and traffic levels of illumination coverage areas of each intelligent lamp pole group are predicted through a traffic prediction model, a remote main control platform generates corresponding brightness control instructions according to the traffic distribution area and the traffic levels, and brightness of intelligent lamp poles is adjusted after the brightness control instructions are sent to the intelligent lamp poles; therefore, the intelligent lamp post brightness can be improved when the traffic is large, and pedestrians can observe the road surface conveniently under high brightness so as to ensure the safety of the pedestrians; the brightness of the intelligent lamp post is reduced under the condition of lower traffic so as to reduce the energy consumption of the intelligent lamp post; the intelligent lamp post has the advantages of diversity, high practicability and the like.
As a further optimization of this embodiment, the method further comprises:
step a01: collecting the running speed of pedestrians;
step a02: when the running speed reaches a preset speed, determining all intelligent lamp poles on a continuous road section where the intelligent lamp poles are located;
Step a03: and increasing the brightness of all the intelligent lamp poles on the continuous road section from the third preset brightness to the second preset brightness, and recovering to the third preset brightness after the second preset brightness is kept for a second time period.
In this embodiment, when the traffic volume is small, some pedestrians adopt a riding mode, such as bicycle riding or battery car riding, and the bicycle riding cannot generate a light source, and the battery car itself has a small light source coverage area; because the riding mode has higher running speed, and the mode that the brightness of the intelligent lamp post is increased from the third preset brightness to the second preset brightness after the pedestrian approaches the intelligent lamp post is adopted, the field of vision of the riding personnel is insufficient; therefore, the brightness of all intelligent lamp poles on the whole continuous road section is increased from the third preset brightness to the second preset brightness in a mode of step a 01-step a03, and after a period of second time, the intelligent lamp poles are restored to the third preset brightness again, so that the running safety of riding staff can be effectively improved; the whole continuous road section in the embodiment is a road section without an intersection, and the first duration and the second duration can be flexibly set according to actual requirements.
In this embodiment, when the length of the whole road section is longer, a distance can be calculated according to the running speed of the riding personnel, so that the brightness of all intelligent lamp poles in the distance is increased from the third preset brightness to the second preset brightness; after the driver is about to drive off the road section of this section distance, increase the luminance of all wisdom lamp poles of the road section of next section distance again by the third default luminance to the second default luminance to reduce wisdom lamp pole to the consumption of electric energy.
As a further optimization of the embodiment, in a region with large traffic, when the smart lamp post is at the first preset brightness, the consumption of electric energy is large, so as to improve the rationality of energy utilization of the whole control system; in this embodiment, each smart light pole group further includes: the solar power generation units respectively provide working power for the lamps of the corresponding intelligent lamp post and the main control unit;
Each intelligent lamp pole group still includes: the controlled end of the electric energy centralized storage scheduling unit is electrically connected with the main control unit of the main lamp, and all solar power generation units in the same group are also used for transmitting the output electric energy to the electric energy centralized storage scheduling unit for storage;
The main control unit of the main lamp is also used for scheduling the electric energy stored in the electric energy centralized storage scheduling unit among the intelligent lamp pole groups based on the electric energy scheduling instruction of the remote main control platform.
In the present embodiment, each solar power generation unit includes: the photovoltaic panel and the battery are arranged on each intelligent lamp post, the battery can store a part of electric energy, the photovoltaic panel can generate more electric energy for a region with sufficient illumination, and the redundant electric energy can be transmitted to the electric energy centralized storage scheduling unit for storage, namely, the redundant electric energy generated by the solar power generation units on all intelligent lamp posts in the same group is transmitted to the electric energy centralized storage scheduling unit for storage; in the partial area, the intelligent lamp posts of the same group may have different people flow, that is, the brightness of the intelligent lamp posts of the same group may have inconsistent conditions, so that the electric energy centralized storage scheduling unit is utilized to perform unified scheduling and distribution, and each intelligent lamp post can be ensured to have sufficient electric energy.
Specifically, the method further comprises:
Step b01: acquiring the electric energy storage capacity of an electric energy centralized storage scheduling unit of each intelligent lamp post group;
step b02: determining the required quantity of each intelligent lamp pole group based on the brightness control instruction of each intelligent lamp pole group;
Step b03: according to the demand of each group of intelligent lamp pole groups and the electric energy storage amount of the electric energy centralized storage scheduling unit of each group of intelligent lamp pole groups, determining the electric energy supply and demand distribution state of each electric energy centralized storage scheduling unit, wherein the electric energy supply and demand distribution state comprises the following components: the electric energy is sufficient or needs to be supplemented;
Step b04: when the electric energy supply and demand distribution state of the electric energy centralized storage scheduling unit is that electric energy needs to be supplemented, generating an optimal scheduling scheme for scheduling electric energy to the electric energy centralized storage scheduling unit by the electric energy centralized storage scheduling unit with sufficient electric energy based on a preset algorithm;
Step b05: generating an electric energy dispatching instruction based on the optimal dispatching scheme, and sending the electric energy dispatching instruction to a main control unit of a main lamp through a 5G base station; the main control unit of each main lamp controls each electric energy centralized storage scheduling unit respectively so as to realize electric energy scheduling among groups.
In this embodiment, the consumption of electric energy by the intelligent lamp pole group in the area with higher traffic is larger, and when the electric energy generated by the intelligent lamp pole group is insufficient to provide the electric energy consumption under the brightness, the electric energy of the intelligent lamp pole group with other sufficient electric energy needs to be concentrated, stored and scheduled in the electric energy concentrated storage and scheduling unit; in order to improve the rationality of electric energy allocation among groups, the embodiment generates an optimal scheduling scheme from an electric energy centralized storage scheduling unit with sufficient electric energy to the electric energy centralized storage scheduling unit based on a preset algorithm; the preset algorithm in this embodiment is a particle swarm algorithm, and an optimal allocation scheme is drawn by using particle swarm algorithm rules, so as to ensure that the electric energy centralized storage and scheduling unit of each group allocates redundant electric energy to other areas on the basis of meeting the electric energy required by self illumination.
According to the embodiment, through the steps b 01-b 05, the dependence of the intelligent lamp pole groups on a power grid can be effectively reduced through electric energy allocation among the intelligent lamp pole groups, and the utilization rate and rationality of energy sources are improved.
