The invention discloses a Wi-Fi (wireless fidelity)-based intelligent traffic car and road quick communication system. The quick communication system comprises workstations arranged on each car and wireless access point arranged on roadsides, the workstations and the wireless access points both comprise Wi-Fi communication protocol-based software frameworks, each software framework is internally provided with a short message processing module, a short message protocol module and a system call interface, the short message processing modules are connected with the short message protocol modules, the short message protocol modules are connected with the system call interfaces, the short message processing modules are also connected with a management pack dispatcher, the management pack dispatcher is connected with an MAC (media access control) layer, and the MAC layer is connected with a physical layer. By uploading the short message receiving and sending function modules into the Wi-Fi communication protocol-based software frameworks, cars can quickly obtain road condition information, and the intelligent traffic system can collect information of cars on roads quickly, and feeds back the information to each car.
Description
technical field [0001] The invention relates to the field of intelligent transportation systems, in particular to a Wi-Fi-based intelligent transportation vehicle-road rapid communication system. Background technique [0002] In recent years, Wi-Fi technology has developed rapidly. In addition to providing fast and convenient data communication, it is also widely used in the fields of Internet of Things such as power monitoring and environmental water conservancy monitoring. Wi-Fi follows the IEEE802.11 protocol, which defines two types of devices. One is a workstation and the other is called a wireless access point. Wi-Fi network has two working modes: infrastructure mode and ad-hoc mode. If it is set to infrastructure mode, then there is at least one wireless access point connected to the wired network in this wireless network, and it can include multiple wireless workstations at the same time. Ad-hoc mode, also known as peer-to-peer mode or IBSS, every device in the ne...
