Intelligent vehicle perception and street lamp control method for expressway based on wireless multi-hop ad hoc network

Abstract

The invention discloses an intelligent express way vehicle sensing and streetlamp control method based on a wireless multi-hop ad-hoc network, and the method comprises the steps such as establishment and maintenance of the network, multi-hop transmission of vehicle sensed information and on-off control of a streetlamp. The establishment and maintenance step of the network comprises the following steps that a road side unit (RSU) periodically transmits an own identifier, and each RSU is added to an RSU identifier list according to the received signal threshold value of the RSU identifier and starts or re-starts a timer so as to generate and maintain a neighbor road side unit list. The multi-hop transmission of the vehicle sensed information and the on-off control of the streetlamp comprises the following steps that an on-board unit (OBU) periodically broadcasts own identifier, the RUS receives and forwards / abandons the OBU identifier according to a rule and generates and maintains an OBU identifier list, and the streetlamp is turned on or turned off according to the received content and the list content. The method is combined with corresponding hardware platform, so that requirements of express way operators on the intelligent sensing of vehicles and real-time and robust intelligent control of the streetlamp can be met.

Description

technical field [0001] The invention relates to the field of intelligent transportation and wireless communication, in particular to a method for intelligent vehicle perception and street lamp control on highways based on a wireless multi-hop, centerless ad hoc network protocol. Background technique [0002] Expressway road network is one of the most important infrastructures in the country. Its scale is huge and the task of information management is heavy. Improving the level of informatization and intelligence of road network traffic is a key task for the development of road traffic in my country. [0003] In order to improve the safety of driving on expressways, expressway operation and management units have erected street lights for expressways to improve road visibility in bad weather and at night. In order to reduce energy consumption and achieve the goal of green traffic, efficient and automatic expressway intelligent vehicle perception and street light control techn...
