My Winter Olympics Story·Shandong: The power-protection team climbed in the snow just for the full signal
Satellite search complete! ”
“Mesh setup is complete!”
“Mobile WiFi signal is full!” After some intense operation, the members of the emergency communication team from the State Grid Shandong Electric Power Winter Olympics Power Protection Team cheered excitedly!
In order to fully guarantee the communication and communication during the trip to Beijing to ensure power supply, State Grid Shandong Electric Power has dispatched 4 backbones from the emergency management center and the ICT company to form an emergency communication team. Among the many tasks of maintaining power in the Winter Olympics, there is an emergency deicing task for 220 kV transmission lines. Due to the mountainous area, the on-site public network signal is almost non-existent. How to quickly and effectively provide on-site communication guarantee for line power protection personnel has become an urgent problem to be solved by communication personnel.
Plan ahead and study communication solutions early
Before going to Beijing, the emergency communication team formulated the “Satellite Internet + Mesh Extension + WiFi Coverage” in advance according to the requirements of the new generation of emergency command system of the State Grid for emergency communication improvement and the on-site environment and actual communication needs of power protection based on the research on mission requirements The solution allows every power protection personnel to use mobile phones to access the Internet through WiFi without additional equipment, to achieve on-site communication and audio and video signal return and other functions. At the same time, real-life simulation tests and audio and video effect verifications are carried out on key communication equipment such as satellite communication vehicles and Mesh to ensure that the solution is reliable and effective.
Over the mountains, just to choose a “good location”
The emergency de-icing site had towering peaks, a complex environment, and serious signal occlusion. In order to select an unobstructed and good location for the satellite equipment, the emergency communication team went to the site for inspection and testing as soon as possible. “Because the mountain road is rough and the snow is thick, in this case of unknown road conditions, we have to walk into the mountain to explore the path for the communication vehicle and select the location for finding the star.” Communication team member Liu Hai, teammates Li Ran and Zhang Huaiyin passed a It took many hours to travel to reach the destination. After the communication vehicle was in place, they carried Mesh equipment weighing 7-8 kilograms and continued to climb the mountain. In order to find the perfect match between coverage, signal strength and call quality, they often walk several kilometers, repeating the selection and testing process. “This is the ninth time I have come to the mountain to survey. No one knows which device has better signal and which position is better!” Liu Hai said confidently.
Waiting for the day, fully prepared for protection
They are well aware of the importance of the stability of the satellite channel, and they took the initiative to report the application to the central station of the State Grid Information and Communication Company, and opened an 8M “Winter Olympics Special Line” specially for the Winter Olympics, which is dedicated to the transmission of Internet signals. A few days ago, they carried out more than ten times of emergency communication surveys and tests and functional drills on the power transmission site, and successfully completed the transmission of audio and video signals with the power protection headquarters at all levels. “Now that the channel is reliable, the equipment has been tested, and the environment is familiar, it can provide clear and smooth communication signals for power transmission lines.” said Zhu Linan, who was in charge of the testing work.
Where the job site is, the communication guarantee is there. The emergency communication team is always on standby, and is fully prepared for emergency communication support.
