An intelligent street lamp control system

Abstract

The invention relates to an intelligent street lamp control system, belonging to the technical field of street lamp control. The system includes a cloud server, a street lamp centralized controller and a single lamp controller; the cloud server includes a port monitoring service, a database, a short message sending service, and a mobile terminal interface. The street lamp centralized controller comprises a commercial mobile communication transceiver module, a memory, a current controller, a power carrier communication module, a clock module, a position positioning module, a sensor module and afunction expansion module. The single lamp controller comprises a power carrier communication module, a dial switch, a memory, a clock module, a sensor module and a function expansion module. The cloud server sends control commands to the street lamp centralized controller. The street lamp centralized controller controls the single lamp controller, and the single lamp controller controls the switch of the street lamp and the brightness adjustment. The single lamp controller collects the street lamp data at regular intervals and uploads the data to the street lamp centralized controller, whichprocesses the data and uploads the data to the cloud server. The invention supports the upgrading of the old city, is reliable and stable, and has strong expansibility.

Description

technical field [0001] The invention belongs to the technical field of street lamp control, and relates to a smart street lamp control system, in particular to a smart street lamp control system which is especially suitable for the renovation and upgrading of old cities and the construction of vehicle-road collaborative intelligent traffic systems. Background technique [0002] With the continuous development of information technology, the application level of urban informatization has been continuously improved, and the construction of smart cities has emerged as the times require. Building a smart city is of great significance in achieving sustainable urban development, leading the application of information technology, and enhancing the city's comprehensive competitiveness. In the planning and construction of smart cities, street lights have become the key application fields of the Internet of Things in cities because of their two advantages of location information and po...

AI Technical Summary

Problems solved by technology

One is the high cost: since each street lamp is connected to the network separately, a complete set of communication modules needs to be installed on each street lamp, and for the sake of communication distance and communication networking, a large amount of funds must be invested in gateways and network nodes to increase communication forwarding module

[0011] Second, a large amount of communication capabilities and hardware resources are wasted: NB-IOT modules are characterized by energy saving, and can work for a long time using battery power, so the amount of data sent is limited, and each street lamp needs to be installed with an NB-IOT module to transmit data separately. Greatly increased the burden on the cloud server, causing the cloud service to waste a lot of work capacity in establishing connections with street lights; on the contrary, using the base station for communication, the powerful communication capacity and high cost of the base station are completely wasted, and are only used to transmit each Street light data less than 10KB per hour

[0012] The third is that the control is inconvenient. The existing control methods are either all controlled individually, or all are centrally controlled, and even the street lamp power supply is connected in series to achieve centralized control, which buryes hidden dangers to the circuit safety and affects the control effect. It is difficult to support the interval required in special circumstances. Lighting or complex lighting methods

[0013] Fourth, it is not conducive to the upgrading of street lights in old cities. It is difficult to integrate existing street lights into the network by simply adding controllers. It is necessary to add gateways and lay network cables or RS485, 232 signal lines to achieve network access.

And it is necessary to write a unique identification code for each controller, which is not conducive to equipment expansion, and the cost of equipment upgrade is huge

[0014] Fifth, it is not conducive to the safety of the power grid. When the lights are turned on under unified control, the instantaneous current draw is too large, which will greatly affect the stability of the power grid, and even cause the entire section of the road to trip and lose power.
