On August 25, the 25th Games of Shandong Province opened at the Rizhao Kuishan Sports Center. At 20 o'clock, the opening countdown ended, the fireworks were ignited, and the audience was boiling. The webmaster Mu Shaohua slowly put down a hanging heart. Like the rehearsal on the 24th, the on -site electromagnetic environment is safe and stable, the communication broadcast is clear and smooth, and there is no abnormal signal. The marathon -style guarantee mission that the month and the whole station personnel will go all out will achieve a staged victory ...
In order to ensure the Provincial Games, Mu Jinhua, director of the Provincial Radio Management Office, and Ding Baoyu, the director of the Provincial Monitoring Station, led the team to support the opening ceremony to form a joint guarantee team of 33 people in the mobile monitoring station 8 More than 20 sets of inspection and monitoring equipment have been formulated, and the opening ceremony of radio safety guarantee workbooks, work plans, and emergency plans for the opening ceremony of the Provincial Games has been formulated. group.
In order to ensure the Provincial Games, the colleagues in the team have been fighting continuously from early August. The opening ceremony is approaching. Many people have not slept for a week in a row. After the opening of various facilities in the opening ceremony, various electrical equipment such as communication networks, security monitoring, light control, and large screen display are concentrated. Electromagnetic radiation is superimposed, the background noise rises sharply, the electromagnetic environment worsens, the microphone, pockets, and dual workers of the guide team, pockets, and dual workers Multiple sets of communication systems such as command are disturbed. Monitoring technicians conduct carpet monitoring and investigation on the electromagnetic environment inside and outside the venue in groups, fragmentation, frequency bands, and all -weather. Monitoring and positioning 4 interference sources in the field, 16 radio interference and hidden dangers, coordinate and avoiding frequency of 20MHz, for the studio team, for the studio team Provide more frequency recommendations and more spectrum figures. The comrades of the Frequency Management Team stayed at the venue day and night, registered for registered radio launch equipment and distributed "Special Tags for Radio Launch Equipment" 1267, with an approval frequency of 186.
At 20:10, the bright lights and shocking music pushed the opening ceremony to a new climax. Suddenly, multiple monitoring points on the spot found that the key protection band 1.175-1.325GHz appeared a broadband unknown signal. This signal instantly threw a grenade in everyone's heart. Dedicated frequency, this interference will directly threaten the 1,000 drone performances performed by the opening ceremony. What is even more difficult is that according to previous work experience, this GPS interference signal is often large and long distance. It is difficult to be in a short time in a short time. Internal positioning.
Interference is the command, and the guarantee is the mission. The atmosphere in the radio security guarantee command of the on -site radio security guarantee is immediately tense. After a simple consultation, the emergency plan was initiated as soon as possible. The on -site monitoring team immediately monitored and found it. Simultaneously, joint measurement; the fixed monitoring team controls the Kuishan Sports Center fixed station to conduct dynamic analysis and judgment on monitoring data and monitoring orientation; Deputy Commander Xu Haiming immediately reports interference to the comprehensive security team. When I understand the situation, the drone flight control system has also discovered abnormal conditions. The interference signal has seriously affected drone flight. It is anxious investigation and judgment. The incident suddenly, the time is urgent, the situation is serious.
Outdoor radio monitoring is not smooth. Due to traffic control, mobile monitoring vehicles cannot pass freely. As time passed, the predetermined time of the drone performance is getting closer and more urgent. Personnel can only abandon the car to find it, but the hiking monitoring position is low, the signal is weak, the level is high and low, and the direction is unstable. It cannot be accurately located. It can only be used for data comparison in a fast change position.
As time is getting more and more urgent, the high tension and large load exercise makes the technicians feel physical to varying degrees. However Essence Everyone does not need to communicate too much. Countless training and competition have been formed, and the distance is opened tacitly. When you simply report a number, you know the level of the other person's location. General directions, comparison of each other, and alternately, the interference level is getting bigger and bigger, and the direction is clearer, which means that the distance from the interference is getting closer and more. The faith of the mood, responsibility, mission, and responsibility promotes the technicians faster, faster ... Finally, good news came from the group. Send in the car.
After communication and understanding, the vehicle was equipped with a drone counter -control system. In recent days, it has been used in recent days. No interference was found. It was suspected that the device was faulty. After the instructions, the interference signal disappeared immediately after cutting off the power supply of the car, and the drone flight control system returned to normal. At this time, there was only 10 minutes from the scheduled performance time. At 21:15, a huge Phoenix, which is composed of 1,000 unmanned phoenix flying, flying over the opening venue, a healthy figure, gorgeous glory, like a new chapter of the wonderful butterfly change of Rizhao City, with the drone Phoenix After the departure, the intense atmosphere of the radio security guarantee command at the scene slowly dissipated, and the roar of the outdoor roar entered everyone's ears. Then everyone realized that the literary performance was nearing the end, but the most gorgeous movements did not miss it. The opening ceremony of the 25th Games of Shandong Province has achieved a complete success. Warriors of many front fronts such as Industry Credit, Public Security, Fire, Medical, and Volunteers. Under the unified command of the Municipal Preparatory Committee, they work together to cooperate and cooperate closely. It is the "loneliness" behind the opening ceremony. To the faith and persistence in the night, who said that standing in the light is a hero. (Reporter Sui Yanchen Correspondent Zheng Chuanbao)
