Problems solved by technology
However, the collection of traffic environment information by today's traffic system is not comprehensive and accurate enough, and the delay in transmitting roadside data to the cloud server is relatively high, such as the active The sensing device only uses a camera, which is very susceptible to weather and light effects; another example is the patent-"Intelligent Traffic System" which mainly provides alarm and tracking for escape accidents. If the data delay is high, it will greatly affect the processing effect

Embodiment Construction
[0060] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0061] Such as Figure 1 to Figure 4 As shown, the intelligent traffic control system based on the lamppost A provided in this embodiment includes the lamppost A and the intelligent traffic system cloud service platform B. A plurality of light poles A are set at a certain distance (for example, evenly arranged, the distance between adjacent light poles is 100m) and set on one side or both sides of the road. Starting from the light pole A at one end, the traffic network in sequence Light pole A is numbered, where L n is the lamppost A numbered n, 1≤n≤N, and N is the total number of lampposts A in the traffic road network. Each street light pole A can collect traffic information in the corresponding detected road section through the information fusion of multiple traffic sensing devices. Among them, each lamppost A has its own coordinate system, and ...

The invention discloses an intelligent traffic control method and system based on a street lamp pole. The method comprises stepswhen the detected traffic flow information lambda nt of the street lamppole Ln at the t moment is smaller than a traffic flow threshold lambda, starting an edge control mode; judging whether the number Dnt of dynamic targets detected by the street lamp pole Ln at the moment t is greater than 0 or not; if yes, sending a control instruction for improving the light brightness to the street lamp pole Ln and an edge calculation unit in the street lamp pole in front of thestreet lamp pole Ln; if not, judging whether the duration of the dynamic target number Dnt=0 detected by the street lamp pole Ln at the moment t reaches the preset time or not, if yes, sending a control instruction for reducing the light brightness to the street lamp pole Ln. The method is advantaged in that light use of the lighting module can be flexibly controlled according to the actual situation of traffic so that electric energy can be saved, traffic cost can be reduced, and the requirement for environmental protection can be met.
Description
technical field [0001] The present invention relates to the technical field of large-scale urban intelligent traffic and automatic driving control, in particular to an intelligent traffic control method and system based on street light poles. Background technique [0002] Today's street light poles can use technologies such as image processing, single-light control, and system integration to integrate multiple functions such as intelligent lighting, mobile network coverage, charging, and video surveillance. Life provides great convenience. The country vigorously promotes the construction of smart cities, encourages the use of various information technologies or innovative ideas to connect and integrate urban systems and services, so as to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens. The smart transportation system is convenient It is the core part of smart city construction. However, th...
