Abstract

The invention brings forward an underground parking lot LED illumination and guiding system and method based on a self-networking technology. The system comprises LED light fixtures, a parking path planning guiding system, and LCDs installed in a parking lot and outside the parking lot for displaying parking place information of an underground parking lot, and further comprises parking place detection terminals which are provided with ultrasonic sensors and are installed in parking places, a DALI light modulation system, a center sever with double gateways, and a ZIGBEE wireless communication network composed of ZIGBEE modules. The LED light fixtures are integrated to form radar detection sensors installed at upper ends of travel paths of the parking lot; the center server employs a DALI protocol and the DALI light modulation system for communication and realizes automatic light modulation on the multiple LED light fixtures; and the center server employs a ZIGBEE wireless communication mode to communicate with the multiple parking plate detection terminals. The invention further brings forward a method based on the system.

Description

technical field [0001] The invention relates to an LED lighting and guidance system for an underground parking lot, in particular to an LED lighting and guidance system and method for an underground parking lot based on ad hoc network technology. Background technique [0002] LED lamps are a new generation of lighting sources. Under the guidance of the government's policy of vigorously advocating energy conservation and emission reduction, LED technology has developed rapidly in recent years. In the process of lighting renovation and upgrading in many underground parking lots, due to the cost and price of LED lights Higher, it takes 1 to 2 years to recover the cost by saving electricity. How to reduce or reduce the energy consumption of "ineffective lighting" has become the key to energy saving in underground parking lots. More and more LED lighting applications require humanized management lighting systems to maximize the potential of LED energy saving. Most of the mature ...
