A system and method for issuing traffic signals based on wireless local area network

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.

Description

technical field [0001] The invention relates to a traffic signal distribution system, in particular to a traffic signal distribution system and method based on a wireless local area network. Background technique [0002] With the improvement of people's living standards, the number of vehicles is increasing alarmingly, causing road congestion. In order to regulate travel and ensure road traffic safety, it is a common practice in various countries to set up various traffic lights and signs on intersections and roads. Indicator lights and signage have made great contributions to road safety, but both indicator lights and signboards need to be installed on fixed facilities, which cannot solve the notification of sudden traffic conditions. With the rapid development of electronic technology, the ancient Placing warning signs directly at the accident scene has become very backward, and the indicator lights and signs installed on fixed facilities will exist beyond the visual range...

[0002] With the improvement of people's living standards, the number of vehicles is increasing alarmingly, causing road congestion. In order to regulate travel and ensure road traffic safety, it is a common practice in various countries to set up various traffic lights and signs on intersections and roads. Indicator lights and signage have made great contributions to road safety, but both indicator lights and signboards need to be installed on fixed facilities, which cannot solve the notification of sudden traffic conditions. With the rapid development of electronic technology, the ancient Placing warning signs directly at the accident scene has become very backward, and the indicator lights and signs installed on fixed facilities will exist beyond the visual range, or are easily blocked and cause blind spots. Distraction, etc. will also lead to traffic accidents, leaving a painful lesson

Some of the wireless traffic signal release equipment currently produced have low security and are easy to be hacked to release false traffic signal information
