? Liu Cong, 32 years old, born in party member, now works in Anbei Communication Workshop of Antong Section, and is one of the main participants in the quality supervision and acceptance of the internal communication project of Antong High-speed Railway Construction Company. Since 2009, he has been transferred to the high-speed rail workshop, engaged in on-site communication equipment line maintenance 1 1 year, and participated in the acceptance and opening of communication rooms in Xibao, Zhengxi, Daxi and Xicheng. He has rich practical experience and super flexibility, and is not afraid of hardship and perseverance. He is recognized as the pioneer of communication construction in Yin Xi.
? In April, 2020, the early intervention in Yin Xi started. Liu Cong took the lead as the leader of Yin Xi high-speed rail pre-intervention group in Anbei Communication Workshop, and was responsible for the construction and acceptance of 1 1 communication room, 8 communication towers and 3 1.2km optical cable equipment between Anbei Station and Xianyang North Station. He led four pre-interveners to refine the equipment acceptance plan, strictly test the optical cable routing, configure and network the standard equipment, covering the whole process of marking and controlling the construction quality of communication equipment. I rushed to Yinxi Line for two consecutive months, urging the construction unit to rectify 255 problems existing in equipment and housing construction to ensure the safe and smooth trial operation of Yin Xi high-speed railway.
? In late May, according to the requirements of resource integration of the group company's station area, the construction progress of Yin Xi communication room of Xi North Station was accelerated. On June 10, the first batch of RBC services of the relocated equipment were put into use, followed by high power supply, transmission, integrated video, mobile ring, disaster prevention and other services. In order to ensure the completion of equipment relocation on schedule and the quality of computer room construction, Liu Cong often "soaks" in the computer room all day to overcome the harsh environment such as intense heat and mosquito bites. Cooperate with the construction party from equipment assembly, cable climbing installation, optical cable routing, equipment commissioning and opening, performance testing and account establishment. Every link is strictly controlled, and the direction of every equipment and cable is well known. Everyone calls him the "active account" of Yin Xi Computer Room.
? On September 3rd, 65438, Shaanxi Xi 'an high-speed railway joint debugging test was officially launched. When the comprehensive inspection vehicle repeatedly passes through Shiheyang Railway Station, the inspection data shows that the long mileage of this road section is greatly attenuated, and there is a safety hazard of C3 wireless connection overtime. On the basis of consulting the network structure, Liu Cong found the fault point accurately by comparing the test data on the spot. Replacing the power divider of Shiheyang Railway Station with a 3dB bridge successfully solved the attenuation problem in this section, and provided a good communication network guarantee for the safety of the trial train.
? Liu Cong, a soldier, is decisive, confident and responsible. On the first page of his work notebook, he wrote: "Frustration at work is inevitable, but you must never bow your head and shrink back. You must be brave enough to challenge yourself, and you must have the spirit of overcoming difficulties and not giving up until you reach your goal, in order to be worthy of yourself and party member! " That's what he wrote. He did more.
