Self-organizing emergency communication network system and communication method

Abstract

The invention relates to the communication field, and particularly relates to a self-organizing emergency communication network system. The self-organizing emergency communication network system comprises an Ad-hoc self-organizing network, a first communication unit, a second communication unit and a remote command center, wherein one end of the Ad-hoc self-organizing network is connected with the first communication unit; the other end of the first communication unit is connected with the second communication unit; and the second communication unit is connected with the remote command center. The invention also relates to the communication method of the system. The method comprises the following steps of: establishing Ad-hoc self-organizing networks; connecting all Ad-hoc self-organizing networks to the input / output end of the first communication unit; connecting the input / output end of the first communication unit to the input / output end of the second communication unit; and connecting the input / output end of the second communication unit to the input / output end of the remote command center. The self-organizing emergency communication network system and the communication method are mainly applied to the aspects of tactical communications, homeland security, dibaster assistance, fire emergency disposal and the like.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a self-organized emergency communication network system (Self-organized Emergency Network System, hereinafter referred to as SENS); meanwhile, the invention also relates to a communication method of SENS. Background technique [0002] The current communication network is based on fixed, base station and cellular, which can only meet the daily normal use. However, in the application fields such as emergency rescue, disaster rescue, homeland defense, public security, and fire emergency response, any small error in the critical state of the conventional network will It will lead to the paralysis of large-area communication systems; on the other hand, the current radio system can only provide a limited number of users or cellular area coverage, or has limitations in throughput and bandwidth; therefore, the current communication network architecture is not suitable fo...

Problems solved by technology

[0002] The current communication network is based on fixed, base station and cellular, which can only meet the daily normal use, but in the application fields of emergency rescue, disaster rescue, homeland defense, public security, fire emergency response, etc., any small error in the critical state of the conventional network will It will lead to the paralysis of large-area communication systems; on the other hand, the current radio system can only provide a limited number of users or cellular area coverage, or has limitations in throughput and bandwidth; therefore, the current communication network architecture is not suitable for tactical communications, Homeland Security, Disaster Relief, or Fire Emergency Response

[0003] For example, in the Wenchuan earthquake in 2008, all conventional communication networks (whether mobile or fixed) were completely paralyzed. Only satellite communication can still reflect value, but satellite communication also faces shortcomings such as small quantity, high price, and limited local access coverage; at the same time , Rescue and other scenes often gather personnel from different departments, such as fire protection, public security, armed police, civil affairs, medical rescue, water conservancy, earthquake, meteorology, transportation, administrative units of the State Council / provincial and municipal local government departments, etc. Different ministries and commissions often communicate internally Adopting its own system can only guarantee the intercommunication within its own system, but it cannot guarantee the interconnection and collaboration between different teams across departments, which hinders the work efficiency of the on-site / background remote command center; another exposed problem is how to Make ground carriers (vehicles, trains, etc.) and aerial platforms (airplanes, helicopters, drones, airships, high-altitude balloons, etc.) and ships in water areas, ship rescue, etc. form a three-dimensional cross-regional three-dimensional architecture interconnection system , to overcome network obstacles caused by ground obstacles (hillsides, peaks, high-rise buildings, etc.) in rescue

[0004] Chinese invention patent application publication specification CN 102445931A discloses a communication system and method between a satellite and a high-speed moving object, which is suitable for communication between different nodes in the network, but for nodes in different ad hoc networks within a certain range The systems and methods for communicating with each other do not involve
