City LED street lamp remote intelligent control method and device

Abstract

The invention discloses a city LED street lamp remote intelligent control method and device, and relates to the street lamp illumination management technical field; the method comprises the following steps: using main street lamps to collect present road surface vehicle real time information and illumination real time information; calculating the LED street lamp illumination level according to preset road surface information-illumination level rules; selecting a PWM light modulation technology to adjust the main street lamp brightness to the brightness corresponding to the illumination level; using a multi-hop relay mode to send the illumination level to corresponding slave street lamps in sequence through each Zigbee route node, and enabling each slave street lamp to adjust to the same brightness. The method only needs to deploy vehicle and illumination detection modules on less main street lamps on the road, thus collecting road information, adaptively adjusting the main and slave street lamp LED brightness on the whole road, realizing regular self-check of the main and slave street lamps, returning street lamp abnormal information to the server through Zigbee route nodes, realizing city street lamp remote monitoring and energy saving management intelligentization and networking, and saving intelligent street lamp deployment cost.

Description

technical field [0001] The invention relates to the technical field of street lamp lighting management, in particular to a remote intelligent control method and device for urban LED street lamps. Background technique [0002] With the continuous development of information technology and the continuous improvement of urban informatization needs, the construction of smart cities has emerged as the times require. "Smart transportation" leads the construction of smart cities. As an important part of smart city construction, smart transportation is an important breakthrough to solve urban traffic congestion, realize the intelligentization of transportation infrastructure, and promote the sustainable development of the transportation industry. With the gradual deepening of the construction of smart cities, the demand for intelligence and networking of urban road lighting monitoring and management systems is also increasing and the requirements are getting higher and higher.

Problems solved by technology

The power line carrier method, due to the complex and random sources of power line interference, the change of load impedance caused by power line load changes and other factors, resulting in unstable and inaccurate power line carrier transmission, it is not suitable for street lamp lines and ultra-long transmission lines of public transformers and other occasions

Although the communication technology based on the public network is relatively mature, it is necessary to submit an application to the operator and pay a certain fee to use the network, which leads to an increase in the operation and maintenance costs of street lights.

In addition, in places such as remote mountainous areas where GPRS signals have not yet been covered, the network cannot be used
