North China industrial control: High Speed Rail WiFi, make the Spring Festival wonderful all the way home

the Spring Festival is approaching, and many friends are beginning to sell tickets. As China's high-speed rail network has gradually developed over the years, more and more people choose high-speed rail for travel. For long-distance travel, the most important thing is time, and the most important thing is fun. On the long way home, using communication packages all the way is daunting, and the signal is not necessarily good. If there is WiFi, it would be great. You can watch videos recklessly. It may seem Utopian. In fact, in the near future, high-speed rail WiFi will be fully covered. At present, the friction wheel surface in the gearbox of the Beijing Shanghai high-speed railway must not be refueled or splashed with oil stains, and free WiFi coverage of the whole line has been achieved

just imagine how comfortable it would be to sit on the high-speed rail home and enjoy the free high-speed WiFi of the high-speed rail. So how does high-speed rail WiFi work? To deploy WiFi network on high-speed railway, operators generally bury optical cables along the railway and establish mobile signal base stations to provide 3g/4g signals for trains. The WiFi equipment of high-speed railway trains converts the received 3g/4g signals into WiFi signals and transmits them to the carriage. Passengers only need to use high-speed WiFi after passing the certification on Intelligent terminals

however, it is very difficult to achieve a stable, smooth and satisfactory WiFi signal on the high-speed railway with the speed of km/h. It needs to ensure the network stability under the frequent signal switching of base stations and signal towers, and it also needs to withstand the harsh high-speed railway operating environment such as high speed, vibration, turbulence and so on. Therefore, embedded industrial computer hardware with better reliability and security must be selected to support the control hardware system of WiFi devices

as a leading domestic industrial computer brand with more than 20 years of professional R & D and production experience, North China industrial control has built an embedded industrial computer product based on NXP [Freescale] arm platform, with the ability of high performance, low cost, low energy consumption, small size, reliability and durability, impact resistance, vibration resistance, high and low temperature resistance, dust prevention, humidity resistance and other harsh environments, as well as the ability to resist strong electromagnetic interference The advantages of high performance, agile processing capacity, low power consumption, more energy saving, high reliability and high security can meet the technical requirements of high-speed rail WiFi equipment for industrial computer products in terms of high processing performance, energy saving and consumption reduction, limited space, resistance to severe impact, impact and vibration of GFRP anchor bolt tensile testing machine of Jinan testing machine factory, and reliable operation under strong electromagnetic field

the application of high-speed rail WiFi is one of the scenario applications of interconnection + mode in the field of high-speed rail. High speed and satisfactory WiFi will further improve the service of high-speed railway, realize the level of microcomputer digital closed-loop control, and win more chips in the competition with civil aviation. Now that spring is approaching, the peak travel is about to explode. If free and efficient WiFi is applied, it will bring a better experience to passengers. North China industrial control is actively developing more suitable and cost-effective embedded industrial computer products to fully help the arrival of the generation of high-speed rail WiFi superimposed with the impact of the Spring Festival on production
