Title:
SYSTEM AND METHOD FOR RELEASING TRAFFIC SIGNAL BASED ON WIRELESS LOCAL AREA NETWORK
Document Type and Number:
WIPO Patent Application WO/2015/192703
Kind Code:
A1
Abstract:
A method and system for releasing a traffic signal based on a wireless local area network. The method comprises: acquire a traffic control signal and generate a traffic sign signal, assemble and encrypt the signal and release the signal wirelessly; and a terminal receives and displays the signal after decryption. The system comprises a traffic signal source (1) and a terminal processing apparatus (2). The system is simple and practical and is easy to construct, helps to coordinate and regulate the traffic without causing vision blind area or sight blocking in driving, and can also be used for rapidly setting up warning signs in sudden traffic accidents or in temporary construction roads, and is portable, has high release efficiency and covers a long distance, achieves an apparent warning effect, compensates the defect of the release of the traffic signal, and provides voice prompts when the driver is absent-minded. Therefore, the occurrence of accidents is largely reduced, and the traffic safety is effectively ensured. The traffic signal information is transmitted in an asymmetric encryption manner, which is secure and reliable and effectively prevents traffic chaos caused by release of fake information by others.
