What is maritime/maritime police emergency communication solution?

Industry background of maritime/maritime police emergency communication solutions based on Retevis technology:

With the development of the marine economy, the maritime security situation and maritime security situation we are facing are becoming more and more serious. Maritime accidents and fishermen are in distress. Maritime police forces are responsible for public security management, combating various illegal and criminal activities at sea, and safeguarding national marine rights and interests The task of law enforcement is becoming increasingly heavy. Other islands have complex terrain, no large-tonnage wharf, some islands or even wharf facilities, and there are many reefs around the island. Large law enforcement boats cannot directly dock on the island and can only send law enforcement boats to the island. There is no 4G public network signal on the island, making law enforcement more difficult. In order to cope with various marine complex environments, improve the level of automation and informatization of on-site surveillance images of the Maritime Safety Administration, establish a maritime emergency communication system, and realize the front-end visual monitoring function and remote video scheduling function.

Introduction of Maritime/Marine Police Emergency Communication Solutions Based on Retevis Technology:

The maritime/marine police emergency communication system is mainly composed of  individual soldier image transmission, relay station, shipboard equipment and corresponding law enforcement recorder, hand wheat and other accessories. It is a new "wireless " concept. Designed mobile broadband wireless communication transmission system. The system adopts the same-frequency networking technology, supports multi-hop relays, each node can move randomly, the dynamic network of the maritime police ship formation while sailing at sea, the network topology can be quickly reconfigured when the formation changes, and does not affect the entire formation. Wireless communication. Through the wireless multi-hop self-organizing network, each law enforcement boat and the coastal police will report and transmit the live video and audio information to the command ship in time, and they can also exchange information with each other. The operation and work of the maritime police patrol team realizes visual command and dispatch. In addition, the audio and video information received by the command ship can also be transmitted back to the general command center through the satellite communication network. The schematic diagram of the scene application is as follows:

Technology-based maritime / marine police emergency communication Solutions features:

The software radio architecture adopts a common hardware platform, supports dynamic loading and unloading waveforms, and can online configure parameters such as operating frequency, bandwidth, transmit power, modulation rate, and network topology based on actual channel conditions and changes in user status.

◆ Broadband self-organizing network does not depend on base stations, and forms a centerless wireless broadband network efficiently and quickly. Support multi-hop relay, can effectively expand the coverage radius of the wireless network.

◆ The network has the characteristics of automatically selecting the best route, self-organizing and self-healing, and automatically realizes chain, star and other network topologies.

◆ One radio multi-mode, any node equipment can be used as an information collection node, relay node or information output node at the same time when it is turned on. It can be used immediately after being turned on, realizing bidirectional transmission of high-definition video, voice, image and other data.

◆ All IP networking, easy to interconnect, provides IP interface, can realize interconnection with other IP equipment.

Technology-based maritime / marine police emergency communication Solutions Related equipment introduction:

Soldier terminal
The single soldier terminal is a very flexible product. When used, it is carried by the marine police single soldier. The law enforcement recorder or other front-end video and audio collector is connected to it through WIFI to realize the collection and transmission of live audio and video information.
Relay station
The repeater is a very flexible radio communication product. It is fixedly installed on the law enforcement boat. It can be used at any time and any place with one-key boot without configuration and parameter changes. It is mainly used to realize multimedia interconnection between individual soldier terminals and between individual soldiers and base stations.
Shipborne equipment
Shipborne equipment is a high-power, high-reliability and fast-moving product developed specifically for ships, which can complete the wireless transmission of video, images, voice and data. Based on the networking technology, it can complete a centerless multi-hop ad hoc network, and can be flexibly applied to the rapid transmission of wireless ad hoc networks in various complex environments, with a wide range of applications. It can seamlessly connect with the existing IP cable network and flexibly expand the IP cable network. It has the remarkable characteristics of long distance, anti-blocking, anti-interference and high reliability. Mainly installed on the maritime police command ship.
Law enforcement recorders, hand microphones, etc.

Software form
The system software can effectively schedule and manage each node in the wireless ad hoc network system. On the main interface of the system software, the location and trajectory of on-site personnel and equipment are displayed in real time based on the map; one-click audio and video collection, return, call, and help; half-duplex single call, full-duplex single call, group call, strong pull, Group call functions such as forced dismantling, monitoring, recording, etc.; video monitoring, video scheduling functions such as video pull-up, video backhaul, video push, cloud mirror control, video intercom, video conference, etc.
