Complex environment multi-mode fusion emergency communication equipment

Abstract

Complex environment multimode fusion emergency communication equipment disclosed by the invention has the characteristics of maneuverability, high efficiency and economy. According to the technical scheme, an LTE base station module is connected to a switch through a network cable to be connected with a Mesh ad hoc network module, an LTE power amplifier carries out low-noise amplification on uplink radio frequency signals which enter a cavity filter from an LTE antenna and are filtered, down-conversion, analog-to-digital conversion and digital intermediate frequency processing are completed, an LTE baseband board carries out digital demodulation and channel decoding on the signals, the data is converted into an IP data stream and the IP data stream is transmitted to a switch; after the Mesh baseband board performs baseband processing on the data stream from the switch, the Mesh power amplifier linearly amplifies the power and transmits the power to the antenna feeder through the filter to be sent out; and the remote Mesh equipment receives and processes the data, transmits the data to a core network of an operator through a VPN transmission channel authorized by the operator, performs routing exchange in the core network, and establishes communication with other handheld terminals of a public network.

Description

technical field [0001] The invention relates to the field of multi-mode wireless communication technology, in particular to a multi-mode fusion emergency communication device in harsh environments such as natural disasters, major emergencies, geological disasters, and uncertain forest fires. Background technique [0002] When a disaster strikes, how to organize rescue as soon as possible becomes the primary task of the emergency rescue team. In recent years, earthquakes, mudslides, and collapses have occurred frequently. When disaster emergencies or major disasters occur, the ground communication infrastructure is often damaged, resulting in the paralysis of the communication network in some areas, and problems such as communication interruption or instability. Once the communication is interrupted, it is necessary to use different life search and rescue equipment and other means in different scenarios to establish an on-site communication network to communicate with the rea...

AI Technical Summary

Problems solved by technology

[0003] 1. There are many types of emergency communication system equipment, there are multiple central equipment, and a unified platform has not been formed. Interconnection and data sharing between various emergency systems have not been realized

[0004] 2. Low equipment integration, heavy equipment, and many connections require professionals to install, and the opening time is long, which cannot meet the rapid response requirements of emergency communications

[0005] 3. Communication relies on special industry terminals, and emergency workers carry multiple emergency communication terminals, which brings inconvenience to rescue work and increases the burden on rescuers

In various emergency rescue scenarios such as earthquake rescue, it is inconvenient for rescuers to carry large equipment or backpack communication equipment that is too heavy

[0006] 4. The transmission network of the emergency communication system is mainly wired network, and the application of wireless network is not yet perfect, especially in complex mountainous environments such as high mountains and canyons, in super-long railway tunnels, and heavy rain and rain decay. There is a lack of emergency communication means

As the scenarios of major emergencies or catastrophic disasters become more and more complex, the requirements for emergency communication capabilities are getting higher and higher. A single product or solution can no longer meet the emergency communication needs at the critical moment, and emergency rescue urgently needs a more comprehensive solution. plan
