"The system is ready for communication..." Chen Hailin, a wireless technician and a third grade Sergeant major of a navy communication unit, was nervously carrying out the task in a communication machine room in the mountainous area of central China. After 17 years in the military, Chen Hailin has grown from an ignorant recruit to a "hundred good sailors" in the navy. Chen Hailin's unit is an important communication hub for the entire army. Officers and soldiers often rely on radio waves in rugged mountain roads and cliffs far from the ocean. They are the strong guarantee of the communication battlefield, chasing dreams and strengthening the army's journey in the mountains and seas. One evening this year, lightning and thunder flashed outside the window, and the strong wind and rainstorm pounded the window crazily. Didi Didi! "Suddenly, a piercing alarm sounded from the terminal of a naval communication unit's computer room. Signal loss emergency alarm! Contact interrupted! "The shift leader Abdul Aini immediately approached to investigate and determine the cause of the fault, and reported it to the chief shift leader and company commander. Immediately activate the emergency plan. "The repair team quickly took action, counted and loaded equipment, and rushed to the fault point. Due to heavy rain and poor lighting conditions, the emergency repair team officers and soldiers changed to hiking after the vehicle arrived near the fault point. Wang Xun, who had just been discharged and voluntarily applied for deployment, discovered the location of the breakpoint as soon as he was familiar with the route. Upon inspection of the scene, it turned out that the tree had collapsed due to bad weather, and the root of the tree had torn the optical cable, causing it to break. Facing the complex emergency repair environment, battalion commander Chi Kai calmly responded: "Drivers immediately set up tripods and road warning signs, wear reflective clothing, and eliminate the safety hazards of Roadworks" "Technicians Wang Heng and Liu Zhiyan divided the emergency team into two groups, and worked together to excavate both ends of the breakpoint"... The more complex the emergency repair environment, the more the real level of officers and soldiers will be tested. On the left side of the breakpoint is the road, and on the right side is a deep pit, with limited operating space. As the main receiver, Li Bing quickly started his work with his legs as a workbench, performing a series of actions such as cable stripping, fiber melting, and fiber winding. After continuous fighting, both fusion points were fully connected. Li Bing, who had been bending down to work on the slope, slowly stood up and moved his already stiff legs. In recent years, the unit has been closely monitoring the issue of high intensity and full load operation of equipment, and has carried out in-depth "feather swapping and upgrading" activities for weapons and equipment. By carrying out lightning protection renovations on key equipment and control circuits, the unit has improved its resistance to damage in lightning weather; Install a current limiting starting resistor cabinet and improve the high-temperature insulation process to solve the problem of frequent coil burning; Optimize the control system of diesel generator set and enhance the stability of power supply. At that time, when the new communication system was first built, all the equipment was brand new. How can we make a fist out of all the standalone devices? Everything is difficult at the beginning, as long as you are willing to climb, "said retired senior worker Mao Junsheng. In order to quickly familiarize their personnel with the new equipment, they concentrated their backbone forces while following the manufacturer to install and debug the equipment, while conducting theoretical learning and technical breakthroughs. In the past two years, we have independently compiled more than 1.8 million words of materials covering six majors, including the "Equipment Training Manual" and "Equipment Operation and Maintenance Regulations". At the same time, exploring the group training method of "task level by level decomposition and capability level by level synthesis", the communication support capability has been preliminarily generated, successfully assuming the combat readiness duty task of a certain naval communication network, and becoming a key link in the entire military information and communication network.
