The definition of emergency communications: that is, the transmission of audio/video signals and data signals among various regions after emergencies. Nowadays, many government agencies and enterprises and institutions have applied emergency telecommunication technology to emergency communications vehicles and provided important help for the work of all units.
The communication command vehicle is mainly composed of Hanhsx's central control system, video system, broadcasting system, lighting system, and power supply system. After completing all the contents of system integration, the communication command vehicle arrived at the scene and the system transmitted images and sounds through the Hanhsx system to emergency centers of several tens of kilometers and several hundred kilometers for the center to make emergency disposal plans. The ground command center and the emergency communication vehicle are equipped with separate dispatching systems. The dispatcher and video server can be used as the master-slave relationship. The equipment in the on-site emergency communication vehicle can upload the on-site data to the command center total server in real time as a secondary dispatching system. Or in the videoconferencing system's branch venue; in the case of satellite link pressure or failure, the on-site emergency vehicle dispatch system is self-contained, and can completely command and dispatch on site independently, and can hold local video through the video server of the on-site emergency communications vehicle. Meetings, video recording and saving of local video information greatly reduce the pressure on satellite links. Through the multi-service job terminal video equipment and vehicle video terminal, the live image will be uploaded to the emergency communication vehicle or command center in real time. The video server of the emergency communication vehicle or command center will be output to the monitoring station for real-time display. The image is clear and the picture is smooth. The command center Leaders can make various real-time decisions based on live images.
The emergency communication vehicle is equivalent to a mobile base station, and integrates intelligent power supply and distribution systems, wireless private network communication systems, microwave communications, image acquisition and transmission systems, and high-light illumination systems to form a multi-purpose, multi-routing communication network. The effective transmission of audio and video signals at the site and command center can be used as a temporary command center on the spot, providing a powerful equipment guarantee for realizing on-site observation, on-site decision-making, and on-site commanding in handling emergency events.
The POLYKEN 942&955 System is a multi layer coating system designed for the corrosion protection of pipelines operating in highly corrosive environments and exposed to high mechanical stresses that may be present particularly on large diameter pipes. The system consists of POLYKEN#1027 liquid adhesive,POLYKEN #942 three-ply anti-corrosion inner layer and POLYKEN #955 mechanical outer layer and is fully certified to the DIN 30672 and EN12068 standards. The 3-ply adhesive system produces a strong cohesive bond to the primed steel surface, at the spiral overlap and to the mechanical outer layer. The tough mechanical properties of the outer layer provide protection to the pipes during handling and installation.
