With the rapid development of the city, the country is prosperous and prosperous. The superior living conditions are the unprecedented development of our lives. Faced with a developing society, the development of communication facilities is also important. Severe rains and tornadoes engulfed some time ago, and the local communications facilities were destroyed. Therefore, for the communications sector, the advent of emergency communication vehicles plays a good role in our reconstruction of post-disaster reconstruction communications. I will now introduce to you the working principles and applications of emergency communications vehicles .
First of all, the working principle of the emergency communication vehicle is to provide wireless communication full-area coverage for the rescue site through the vehicle-mounted base station equipment on the communication vehicle. The on-site workman deploys the communication vehicle-mounted terminal as well as the video-screening equipment through hands-on or multi-service work terminals, and releases the latest situation information for the command center. The GS8 gateway carried by the on-site emergency communication vehicle can directly connect the GSM and PSTN public network telephones to the onsite security system.
Second, the major operators of emergency communications vehicles are relatively strong and are spread over three major communications groups. It is mainly used in wireless public communication facilities. For example, the first is China Mobile's wireless communication facilities, followed by China Unicom's wireless communication facilities, and the third is telecommunications. Therefore, emergency telecommunications vehicles are the top priority for maintaining emergency events. It not only maintains normal communications but also ensures normal communications. Maintained the maintenance of communication equipment and the first-hand news and resource information for the disaster-affected areas. The BTS antenna equipment is now installed in the emergency telecommunication vehicle. It is used in people’s unconventional situations such as widespread gathering of major activities or unexpected events that cause communication disruption in a certain area. situation.
Finally, the emergency communication vehicles are also widely used in special government agencies. For example, earthquakes, fires, and meteorological disasters occur. In many cases, it is not possible to rely solely on public communication networks. Therefore, emergency departments have their own dedicated wireless communication network. The safety and seriousness of the situation are guaranteed under special conditions.
The above is to introduce the working principle and use of the emergency communication vehicle. It not only makes the maintenance of communication equipment the main equipment, but also our state functional departments to deal with emergencies, restore the most important information and communication communications vehicles, for our lives.

HDPE steel strip reinforced corrugated pipe Features
n High pressure bearing capacity, high impact resistance capacity: pipe is steel strip reinforced, high ring stiffness , good adaptability for any foundation conditions;
n Economy: lower cost than the specifications of other plastic pipe, light weight, save transportation and construction costs, easy management and maintenance; large diameter, high ring stiffness;
n Chemical resistance: will not be corroded by sewage, waste water and chemicals, will not be corroded by the substances in soil, it will not be damaged by plant roots;
n Anti-aging: the pipe is generally in black color, can withstand the direct sunlight in the stacking and construction process.
n Excellent wear resistance, Better than steel pipe.cast iron pipe, cement pipe;
n Superior drainage: small water flow resistant in the inner wall, Drain fast, Strong water passing ability. large fluid flow.
n The composite of each layer is carried out in the molten state of the plastic, which is completely different from the winding pipe (medium hole wall tube), so the composite fastness of each layer is very reliable;
n Pipe can be used hot melt welding, clamp type rigid connection, heat shrinkable belt connection and other connections, suitable for different piping system requirements, convenient and reliable.
