Abstract

The invention provides a highway emergency communication network based on free space optical communication. The highway emergency communication network based on the free space optical communication comprises a communication terminal, a data collection system, a movable access point, a fixed access point, an area communication station and an emergency command center, wherein the movable access point communicates with the fixed access point through an atmosphere channel provided by free space optical communication equipment. By utilizing the network provided by the invention, the instant communication between the emergency command center and field staff can be effectively realized when a highway accident happens; and the network provided by the invention has the advantages of high band width, flexibility and rapidness in network establishment, transparent protocol, strong multi-service support capability, low cost, interference resistance, safety, environmental friendliness, easiness for introduction and opening of an existing highway private communication network, no need of frequency application, and the like.

Description

technical field [0001] The invention relates to the field of emergency communication, in particular to a highway emergency communication network and method based on free space optical communication. Background technique [0002] With the rapid development of transportation, the mileage of expressways in our country has been increasing, which has improved the structure and efficiency of land transportation in our country, but it has also brought about the negative effect of increasing traffic accidents. Therefore, strengthening the construction of traffic emergency command and dispatching capabilities and improving the level of traffic emergency response are important issues facing my country's transportation industry. When a traffic accident occurs, it is the key to carry out accident rescue to grasp the specific information of the accident scene in the first time and establish an effective information exchange channel between the scene and the emergency command center. Thi...
