Summary of locomotive work

Dear leaders and colleagues:

In the past 2019, under the correct leadership of the terminal, with the help of comrades, I feel that I have improved and improved my mind, work, study, and personal qualities. I will talk briefly about my performance in various aspects over the past year.

I. Ideological and political aspects:

I firmly support the party's leadership, support socialism, safeguard the motherland's territory through the novel network, complete the ideology and the party committee of the terminal, and implement various security systems in the work, especially during the Beijing Olympics. As a grassroots staff member, I have worked hard to do my job, taking the security audit of the terminal as an opportunity to find out the hidden dangers and weak links in the work, improve various rules and regulations and basic accounting, and stabilize and maintain the stability of the terminal. Work is a plus. Because I have always believed that doing my job well is the best support for maintaining stable work.

Second, the performance of the work in the past year: 2. Pay close attention to safety and improve the level of locomotive work. The locomotive work has always been implemented in the "Safety First Prevention" policy of the Civil Aviation Administration of China. In response to the eight-character policy of the Civil Aviation Administration, in 2019, the locomotive engineering team completed. The following work: 2) Focus on safety, continuous improvement and safety throughout the entire work. In 2019, in combination with the notice and meeting spirit of the terminal and the superior authorities, the aircraft completed special inspection measures for thunderstorms and improved winter snow and ice prevention measures. In the past, When we were working at Lhasa Airport, there was basically no thunderstorm weather and aircraft icing. Source: Civil servants online. Now, due to the large local temperature difference, high humidity, thunderstorms and icing conditions, the aircraft is summing up the past 2 years. On the basis of experience, various inspection and preventive measures have been perfected, and special inspection measures for thunderstorms have been formulated in combination with the actual conditions of local airports. Ice and snow in winter are attached to the surface of aircraft, which will pose a great hazard to flight safety and even cause aircraft. Destroying flight accidents, therefore, in the winter, we strengthen the defense/defrost The training, combined with the anti-icing/de-icing worksheet, seriously strengthens the implementation, puts safety first, and does not let the aircraft that do not meet the release standards. In response to the continuous demonstration of the aircraft brake pad wear indicator on the runway, we notified the Chengdu maintenance base according to the business process, checked the flight back to Chengdu in Japan, and gave written explanations to several consecutive cases. The Chengdu maintenance base has affirmed our careful and meticulous work style. We have developed special inspection measures for aircraft landing gear in response to this situation, implemented a cross-checking system, and reported it to the safety inspector for filing.

The above are some typical cases of the 2019 locomotive, which made me realize that I should actively think in the work, find the problem and find an effective solution, find the crux of the root cause, change the work flow, and eliminate the safety hazard from the system. To improve the level of security of the aircraft.

Summarizing the work situation in the past year, I feel that in the future work, I must strengthen the following aspects: First, the proactiveness of the work is not enough. In many cases, the leaders are waiting for the task, instead of taking the initiative. Work plan, think more, find more problems; second, assist the department in full-time position, do a good job in the overall work of the navigation department, do not rest on your own feet, have a pioneering spirit, not afraid of offending people, not afraid to lose face, do not think that doing good work on me Everything is fine. The third is to improve the business level. The professionalization of the navigation department is very strong. There are great differences in various professions. Only by working hard to improve their own business level can we find problems and find weak links and make continuous improvement.

My debrief is over, please criticize me!

thank you all

According to the weekly operation quality analysis of Yinbei network, the riverside U4 light receiving and transmitting unit received the B1\B2 error code in April, timely analyzed and judged, and replaced the Shizuishan U14 optical receiving and transmitting unit to solve the problem of the quality degradation of the transmission channel. In September and October, Pingluo machine room was collected and analyzed according to the optical power of NOKIA equipment in the area. It was found that the Dawukou machine room received the Pinglu direction, and Pingluo received the U2 optical power drop of 3dB and 2.1dB, which passed the core test and network management test. , calculation of data, analysis of the reasons for the decline of data in a timely manner. On September 3, through the network management monitoring, it was found that the receiving power of Pingluo NOKIA equipment U2 and U14 was close to the receiving overload point, and the corresponding solution was formulated in time to solve the problem and eliminate the hidden danger of the equipment. On October 24, Dawukou NOKIA equipment U4 received B1 and B2 errors in the riverside direction. The maintenance crew organized personnel to analyze and solve the problems in operation. Pingluo and Dawukou computer rooms timely check and summarize the network data for the current situation of the small number of small physical circuit shutdowns, and create conditions for timely verification and modification of resources.

In September, the district operation and maintenance department went to the Pingluo Bureau to conduct equipment inspections. Through the network management, data on the performance, cross-connection, and clock configuration of the equipment in Yinbei were viewed and analyzed. The ALCATEL and NOKIA equipments in the Yinbei ring, Dawukou engine room. The 2500+ and METRO3000 equipments have been tested for switching. This equipment inspection has solved the optical path error problem of the ALCATEL equipment Pingluo station and the NOKIA equipment Pingluo and Anleqiao clock tracking have not formed protection. Pingrohua changed the optical port of the 11-slot SL2 on the local ring network to the optical port on the 12-slot SL2 disk, which solved the unsafe hidden danger caused by the upper and lower optical ports. For the Pingluo machine room GL2000 monitoring equipment can not test the fault of Pingluo monitoring station. In the third quarter, the district bureaus Wang Ruidong and Jia Shunquan came to Pingluo Bureau for verification of fixed assets cards. The inspectors scanned the equipment one by one and the machine by piece, and checked the accounts one by one, revisiting the cards with errors and missing items. Paste it.

In order to reduce the obstacles in the circuit when the circuit is rushed, better maintenance work, so that the line operators and crew members are familiar with each other's work conditions and environment, to achieve the purpose of the aircraft line, September 3, 29, the head of the aircraft And the flight attendant who just took over the shift to the construction site of the 32nd spur of Pingluo Railway Station, the construction site of the 50xxxx Jinghu Yinlan first-class optical cable on both sides of the construction site and the second dry 8-core optical cable of the same ditch to carry out the "three-line" To complete the safe relocation of optical cable lines. The crew of the crew organized weekly training and discussion, organized simulation exercises for many times, and arranged the riverside engine room entry and exit crew to systematically train the riverside stationed linemen. The main optical equipment was installed from the riverside machine room. The arrangement of the two dry optical cables in the ODF frame to the direct connection of the line fibers in the A and B directions and the dispatch of the fault circuit to the standby optical channel, and the simulation exercises of the Pingluo and Dawukou engine room personnel were carried out several times. At the same time as the local network equipment inspection and operation plan, the crew is required to familiarize with the route direction and pole condition of the local network cable line, strengthen the joint function of the line, and the line personnel enter the local network room at the same time to familiarize themselves with the transmission equipment and system. The opening of the core assists the crew to open and stop the circuit, and the crew members use the instrument for on-site training.

The maintenance class combines the conditions of the first and second trunk lines and the network structure of the local network room and some large customers. The backbone of the organization technology has thoroughly improved the circuit rush plan from several aspects such as equipment, lines, power supplies and spare parts. The Siemens Fault Maintenance Class, which took place on August 26, organized a quality analysis meeting in time to summarize and analyze the deficiencies in the obstacle handling process and discussed the scheduling of the circuit after the intervention of the intelligent switching system, and added the feasibility results of the discussion to the circuit. Grab the plan to make it more perfect and feasible. And systematically learn and analyze the rushing plan every week. In the process of continuous learning and drill, we will supplement and improve the deficiencies in the rushing plan, and strive to develop the program in a practical and feasible direction. Through one year of study and continuous improvement of the rushing plan, all members of the maintenance class have made great progress and improvement in the network composition, system opening and aging time of the whole network.

On-the-spot analysis and discussion on the obstacles of ALCATEL equipment on April 25, detailed analysis and summary from the aspects of obstacle handling, reverberation, request, report and so on. In combination with the delay of the 24th day of the solar cable line, the inspection of the equipment and the network management system in the equipment room is not timely enough. The Pingluo Bureau and the maintenance class strictly follow the requirements of the transmission bureau to report the fax to the alarm of the maintenance area equipment and the power cabinet. The alarm status is detailedly sorted and rectified; all the interventions for the sound protection alarms of other equipment and network management systems in the maintenance area have been completed. According to the actual maintenance class of the maintenance work, the equipment and network management system inspection system should be supplemented and discussed in a timely manner, aiming at ensuring the safe and smooth network, and eliminating the time-consuming incidents caused by equipment and line rushing due to obstacles in equipment and lines. occur. In terms of upgrading the network software version of the device: In June, the software version of the two-dimensional Huawei SDH2500+ device was upgraded. In August, the upgrade of the software version of the ALCATEL device and the local network bonfire device was completed.

In the maintenance work of the local network equipment: assisting Yinbei Telecom Branch and UT Company to carry out on-site survey and time slot design for the equipment network transformation of Pingluo local network West Ring, South Ring I, II3xxxx site. Cooperate with Dawukou Telecom Branch to complete the relocation of Pingluoxiling, water pipe station and Shuguang local network room. In May, the Pingluo bureau line jointly cut the 32-core optical cable of the Dawukou local network Dawukou-Shengli, a tree, a plant, and the second plant. The cut-off system was used in the early stage of Taixi 622M, inspection, and ADSL. The xxxx system performs scheduling and recovery, and considers the Taixi network security to share the transmission mode of the optical cable transmission route. According to the requirements, it will open 13 pieces of 2M circuit of Yinbei ICBC. At the same time, it assisted Dawukou branch to check and test the Yinbei ICBC network. In the implementation of the local network equipment operation plan, the patrol video and equipment and circuit operation plans of the 13xxxx site in the first to fourth quarters of Yinbei were completed in strict accordance with the transmission bureau planning standard; the obstacle passage was confirmed for the first event in the obstacle. And distance, at the site of the condition, the spare core is connected to the Pingluo and Dawukou machine rooms one by one, creating various conditions for the compression of the obstacles. In order to carry out the fine management of the maintenance work, the configuration data of the node IP address, working mode and protection mode of the monitoring of the transmission network management system of Dawukou and Pingluo machine room are carefully sorted out. After the Pingluo UT is moved into the monitoring room, the idle 2M channel is checked and the alarm is forbidden. All the invalid alarms on the network management are eliminated. Perform a switching experiment on the four rings of the Pingro local UT device. Through the above work, it helps to further grasp the performance of the local network equipment, improves the speed of the maintenance personnel to reflect the alarms and faults, and is beneficial to compressing the local equipment and the circuit obstacles. According to the network management performance data collection and analysis, replace the fan of the Huinong mother station, the Huawei 155/622M optical transceiver of the Shangyingzi computer room, the light board of the 155/622M optical transceiver IU1 right optical transceiver of the Xinghuo engine room, and the original high-order channel performance on the optical transceiver of the farm computer room. The alarm disappears and the running quality of the local network system is improved. On August 22, according to the network management, the Dawukou parent station received the HP-RDI alarm in the west direction, and the circuit to Jianxi was completely interrupted. After replacing the 155M optical disc in the direction of Dawukou in Jianxi engine room, the circuit returned to normal, and the network management system was restored. Give full play to its leading role. During the local network maintenance operation plan execution, the performance of each transmission node of the local network is collected according to the maintenance requirements, and the local network maintenance operation status is included in the weekly network operation analysis, and the local network maintenance quality is gradually improved.

Pingluo Maintenance Class 2019 Maintenance Work Plan and Suggestions

1. In accordance with the work deployment of the Pingluo Transmission Bureau and the lessons learned from the maintenance work in one year, strengthen the maintenance work in maintaining the quality of communication throughout the network.

Strengthen the maintenance and management of production sites, especially to exert the subjective factors of people, to play and mobilize the initiative and enthusiasm of maintenance personnel. Measures: Strengthen communication awareness and create a good psychological environment in maintenance work. Instruct employees to change their bad work mentality.

Strengthen the maintenance mechanism with network management as the leader, and monitor the operation quality of the whole network dynamically and timely. Measures: Formulate a practical network management, browsing and monitoring system.

Continue to extend and extend the weekly network operation analysis system of the whole network; strengthen the intensity and breadth of analysis. Measures: Communicate and communicate relevant personnel on performance data and online abnormal situations, and formulate corresponding solutions.

Strengthen the maintenance of the local network: in particular, it is necessary to strengthen the management of the network management system and the inspection and storage of the equipment, and use the standby machine and spare disk for system rushing and repairing. On the basis of the second, it is necessary to strengthen the organization and update of the relevant network data of the local network; in the summer, it is necessary to strengthen the monitoring of the environment of the modular computer room to prevent accidents. In the case of unstable local agricultural power, it is necessary to establish a contact system under unexpected circumstances. For modular computer rooms that cannot be powered in time, it is possible to take the initiative to supply power and compress the obstacle time limit.

According to the quarterly operation of the entire network transmission equipment, it will conduct centralized inspections with the maintenance center to solve the security risks and technical problems existing on the network.

Strengthen the maintenance and inspection and guidance depth of the monthly and weekly maintenance classes, especially the problems in the network management system and online.

Suggestion: Make the PHS of all the employees of Pingluo Long-distance Telecom Transmission Bureau and the ring tones of mobile phones into: CRBT service with the promotion of the protection of optical cable lines, so as to increase the propaganda and market for the protection of optical cable lines.

Summary of locomotive work

Shi Lei, a telephone online correspondent, reported that it took two months for the route to work, and I was also converted from a graduate student to an on-the-job worker. Many of the previous concepts have been redefined, the biggest of which is a more comprehensive understanding of the work.

What is work? Is it a job to complete a task of arrangement? Actually, it seems to be, but it only meets the most basic requirements of the work - the work is done. Just like building a house, after decorating it without decorating it, can such a house meet our requirements?

How do you do it once? In my opinion, a good job includes: the right scope of work, the right working time, the precise level of work, and the deep work improvement.

Let me talk about the first one, what is the correct scope of work. This is easy to understand, that is, what I can do and what I can't do. Work can't covet big, multiple, and full, otherwise it will not help to improve the level of work excellence, but it will leave many hidden dangers. Especially in our aviation field, the requirements for safety and reliability are particularly demanding. Once we have done something outside the scope, this is unsafe and unreliable work. So how do we talk about protecting the safety of life and property of passengers?

The second is the right working time, that is, what time to do something, which is very deep for beginners who have just started working in contact with me. For example, two people are also posing a reflective cone. One person is the master who asks him to go to the pendulum. He goes to the pendulum and let him go to withdraw. He then withdraws. The other is to observe and remove the light by observing the master. The timing of the cone finally makes it possible for itself to generate a sense of when to withdraw, and then to swing or withdraw the cone of light. From the effect point of view, the two work results are consistent - the reflective cone is placed. In terms of their working methods and work efficiency, they are quite different. The former always knows only the mechanical action of the reflective cone. It is a passive work. When the monk hits the day, it can only stay in place forever. The latter, through continuous initiative to deepen their own experience, has grown rapidly. The old saying goes: "Know it but know why." Do not take the initiative to observe, think, why do this, then how do you know how to do a good job, and where to pay special attention. "When do you do something", this is a window through which others can know your attitude towards work.

Third, the precise level of work is what the work is going to do. There are always people who seem to be working non-stop, but the work they actually do is not in place. What is the significance of such work? But on the other hand, if the work only meets the requirements for work completion, it is good. Is it still a case - rubbing the mirror. Its content is very simple, use a rag with red oil to wipe off the oil on the mirror surface of the landing gear, and then wipe it with a clean rag. However, if the degree of work is accurate, there is still a distance: whether to clean the mirror between the inner and outer bushings, whether to clean the groove between the inner and outer bushings, whether to check for scratches or oil leakage after rubbing. It is this small gap that often reflects whether the worker has a rigorous and serious quality.

The last thing is a profound work improvement. "No one is perfect, no gold is enough." No matter how the work is done, there will always be a better way to do it at that time. So this reminds us to think back after finishing a job - how did I get the job done, where is the job better and what needs improvement? It is through this self-evaluation of self-questioning methods that a working method that truly suits you and your environment is formed, and this becomes part of your valuable work experience.

Throughout all aspects of the work, the content of the work is much more than that. There are also factors such as the efficiency of work and the cooperation of personnel. The four points of the above work are the most profound ones I have experienced during this time. I have put these four points into a line and follow this line of thinking. Then the results of the work will not meet the target of the job requirements. Too far.
