Li Zhenquan： Keeping watch in the silent battlefield
In the early morning of March 2016, in the depths of Yanshan Mountain, the spring was chilly. Under the incandescent lamp, it is a busy scene, with people coming and going, sweating on their heads. "All fiber cores of the No.3 rack have been successfully tested, and the equipment can be connected!" A lieutenant colonel officer has no distractions and gives instructions to the walkie-talkie. He is Li Zhenquan, a senior engineer of a communication group headquarters.
Li Zhenquan can’t remember how many times he moved the computer room. As long as the communication rooms of more than 10 companies in the whole regiment are relocated, he will basically be on the scene. From the initial independent connection of various equipment to the guidance of the whole group’s computer room construction, his "marriage" with the computer room lasted for 16 years.
16-year "marriage" with the computer room
When Li Zhenquan graduated in 1998, it coincided with the rapid development of national defense communications, and he was fortunate to experience the great changes in national defense communications from cable to optical cable and from carrier to optical terminal. In June, 1999, when the long-distance trunk line of military communication was changed from electricity to light, Li Zhenquan, who just graduated, was responsible for building a new optical communication room. At that time, no one in the company had contacted the optical transceiver. "In addition to the clear basic theory of communication principle, the first time I saw the actual equipment and saw so many boxes stacked there, I was also big. For the first time, I felt that there was a huge gap between theory and practice." Speaking of the scene at that time, Li Zhenquan smiled.
Day and night, facing the instructions, one equipment is installed, one line is connected, and one port is tested. Li Zhenquan forgets to sleep and eat. A week later, neat equipment, smooth cable arrangement, and the superior acceptance group gave a thumbs up. The computer room they installed has become a benchmark, and the director of communications of a group army also took people to learn from it.
In order not to affect the normal use of the next day, almost every time the computer room is moved, it is necessary to dismantle, relocate, install, cut over and open all the equipment within a few hours before dawn. "Nothing has changed for end users, except that we are working when others are resting, and we are still working when others are working." Li Zhenquan said.
For more than 10 years, dozens of computer rooms have been relocated, and thousands of devices have been connected without a mistake. "Practical and true." When Li Zhenquan was mentioned, Chief Engineer Liu Jizhou blurted out. In 2006, after graduating from graduate school, Li Zhenquan returned to the regiment as an engineer in a technical unit, and embarked on a long road of devoting himself to scientific research and quietly cultivating.
Devote oneself to scientific research and work silently
The original head cabinet has been distributed for a long time, with incomplete information and no circuit diagram. Li Zhenquan used the abandoned head cabinet, dismantled the circuit board, drew by himself, learned drawing, bought chips, and began to study single chip computers. In the old equipment warehouse, he cleaned up an experimental platform and riveted it inside, with no distractions. After half a year’s research, the power head cabinet in the computer room was improved, the volume was reduced by half compared with the original one, and it was cheaper, the performance was more stable and the cost was saved by 60%. Eight years have passed, and some of these improved head cabinets are still on duty, guarding tens of thousands of communication equipment.
The duty stations are scattered, the technical force at the grass-roots level is relatively weak, the equipment alarms, the general business processing is fine, and when there is a big fault, it will be stretched. It often takes a long time for the technicians of the maintenance center to get to the scene, so the upper and lower levels are very upset. Li Zhenquan traveled all the computer rooms, collected information, and communicated with the personnel on duty in depth, and developed a "centralized monitoring and technical support system for remote equipment fault alarm". In the first time, the group communication combat duty room can provide help to the grass-roots duty personnel.
Although the grass-roots technical posts are ordinary, Li Zhenquan has made extraordinary achievements and won the third prize of military scientific and technological progress three times. In the face of rewards, he was very calm and humble: "It’s just that the organization trusted me and put me in a suitable position."
The battery pack is in a floating state for a long time, which is easy to cause aging and damage for a long time, and the battery supply is insufficient. Once the computer room is cut off, the consequences are unimaginable. To this end, he and the professional technical backbone of power supply tried various methods, and finally developed a "switching power supply battery charging protector", which improved the battery life by more than 30%. On this basis, he focused on the separation test of single battery to tackle key problems, and developed the "on-line precision test and performance early warning system of battery internal resistance", which fixed the monitoring point on single battery, avoiding "one bad group and one bad group", greatly improving the stability of battery pack and eliminating the hidden power hazard in the computer room.
Since becoming an engineer, Li Zhenquan has successively completed the survey and construction of nearly 600 kilometers of national defense communication optical cable lines, installed thousands of adjustment and measurement equipment, and laid tens of thousands of indoor cables, effectively alleviating the shortage of communication channels in all relevant directions and ensuring various military communication and liaison needs.
Just to be worthy of the military uniform.
Li Zhenquan, who strives for perfection and is rigorous and realistic in his work, only ignores his wife and children. In 2009, the construction of communication optical cable around Bohai Sea required the construction and installation of dozens of computer rooms and stations along the line, and the equipment had to be adjusted and measured. The task was very heavy. He often left for more than a month, and after a year, he didn’t have much time at home. Li Zhenquan, who mentioned his daughter’s condensation and was not good at talking, had tears in his eyes. He said frankly, "I also want to be a good father and grow up with my daughter." When my wife gave birth, she was embarrassed in the uterus, which caused her daughter’s local brain injury and left sequelae. She couldn’t walk when she was two years old. Now she is a little behind other children of the same age. For so many years, the family’s affairs basically depend on her alone. My daughter’s school holds a parent-teacher conference. In other families, parents take their children with them, but his mother is the only one. The head teacher quietly pulled his wife aside: "I haven’t seen Ning Ning’s father either, and I’m not sure. It’s too tired for you to take care of your children alone, and it’s not a good thing for a single parent to rehabilitate her daughter …" Someone asked Li Zhenquan: "For so many years, you’ve been working day and night, what are you doing?" Zhen-quan Li smiled. "I think it’s worth it …".
In the spring, summer, autumn and winter, the cold is coming and the cool is coming. Li Zhenquan has been training and studying hard for several years. In the grass-roots technical posts, he silently guards the safe operation of national defense communications and equipment with practical actions, integrates his personal ideals and ambitions into the great cause of strengthening the army and rejuvenating the country, and shows the elegance of contemporary soldiers.
