Personal Summary of Operation and Maintenance Work in 2020
Looking back on the past year's work, with the correct leadership of the company leaders and the mutual support of various departments, the Operation and Maintenance Department ensured the smooth development of the operation and maintenance department throughout the year, based on safe production, taking the overall transformation of digital TV as the main task and aiming at user satisfaction.
I. Maintenance of National and Provincial Trunks
1. Carry out regular dust removal and maintenance on national and provincial trunk lines, SDH transmission equipment, equipment power supply and private network equipment to ensure the normal operation of trunk lines and ensure the safe and trouble-free transmission.
2. The air conditioner in the transmission section of national and provincial trunk lines is maintained and overhauled, which ensures the normal operation of the equipment and avoids the alarm caused by the over-limit temperature of the machine room.
3. The transmission room power supply and the front-end UPS power supply are discharged regularly.
4. Install and debug provincial trunk OSN equipment, and complete the installation and measurement of national trunk wavelength division equipment and preliminary measurement of interactive TV front-end equipment.
Second, the daily maintenance of the computer room
1. Daily maintenance: do a good job of machine room duty according to the regulations on machine room duty, report the operation of machine room equipment and power supply to the provincial company on time, fill in the machine room duty log truthfully according to the actual situation of the machine room, measure the output of rectifier cabinet, battery pack and DC power distribution cabinet once a week, clean the dust of equipment dust screen once a week, repair the generator and ensure emergency power supply. Strictly follow the dispatching instructions of the computer room of the municipal company and the prompt of the early warning display system of the General Administration, start the emergency plan for safe broadcasting, do a good job in safe broadcasting during sensitive days, National Day and Asian Games, and realize the normalization of safe broadcasting throughout the year.
2. Program transmission is normal: the front-end receiving signal is normal, and the return program is normal. No abnormalities were found throughout the year. If the digital system signal is unstable for three consecutive days from February 7 to February 9, 65438, please contact the operation and maintenance department of the provincial company in time to confirm that the signal failure is caused by unknown interference in the signal receiving system of the front-end computer room of the provincial company. At present, the fault has been eliminated.
3. Fill in monthly and quarterly reports such as computer room maintenance report, line maintenance report, digital TV signal parameter report, trunk optical fiber preparation test report, digital TV front-end equipment maintenance report and line cut-over report, and report all kinds of reports to Baoji Company before the 20th of each month.
4. Test the trunk optical fibers in Baoji direction and Xianyang direction on time according to the operation and maintenance specifications of the transportation and dispatching department of the provincial company, and report the test results to the transportation and dispatching department on time.
5. Deal with all kinds of equipment failures in front-end computer room in time. Replace 3 satellite receivers and 5 abnormal modulators, maintain the fault of QAM modulator 18 fan, and handle the fault of QAM modulator and multiplexer in the front-end computer room of digital TV.
6. The optical transmission platform of the front-end computer room is reformed. Because the optical transmission platform in the initial stage of network transformation is mainly analog plus digital platform, with the promotion of digital TV overall conversion, pure digital connectors increase, and the original pure digital optical transmission platform can no longer meet the needs. In order to transform the optical transmission platform into a pure digital platform, the equipment configuration of the optical transmission platform was adjusted from the front-end computer room. In the process of adjustment, * * * involves the signals of 265,438+09 optical nodes. Due to the change of optical signal intensity of optical nodes, the output parameters of optical receiver change, and the signals of each optical node are adjusted one by one in time to ensure the normal transmission of signals.
Third, the line maintenance
1. The technical data of optical cable network in the whole region were improved and sorted out, and the optical cable cutting data caused by line reconstruction was changed in time.
2. Test all the light spots in the whole area, improve the technical parameters, and test the optical signal intensity of each optical node and the signal output power of each channel of the optical receiver.
The whole region has done a lot of work in operation and maintenance throughout the year, handling user complaints and maintenance work in time, and also cooperating with the marketing department to do a good job in the overall conversion of digital TV; Cooperate with the engineering department to do a good job of opening the optical node signal in the new residential area.
Fourth, user service.
Because the whole area of the network has realized fiber-to-the-home, network failures have been significantly reduced. With the completion of the overall transformation of digital TV, the number of digital TV users has increased, and the indoor maintenance work of users has increased significantly, with an average of about 30-50 households per day. The main user reported that the signal parameters were not up to standard due to the user's private modification of indoor wiring, and the set-top box could not be viewed normally after installation, which was time-consuming. Due to the increase of such failures, the maintenance services generated by users who can't use set-top boxes have also increased greatly.
Working ideas for 20__ years
First, the national trunk, provincial trunk, transmission room and cable TV room shall be well maintained according to the requirements of provincial companies.
Second, strengthen line maintenance and safety management.
First of all, ensure the transmission safety of branch and trunk lines, strengthen the management of cable TV transmission safety, ensure network security, and achieve five diligence: diligent inspection, diligent visit, diligent patrol, diligent reflection and diligent communication. In case of emergency, report it at the first time, and the emergency repair personnel will carry out maintenance in time. Ensure the safe transmission of signals in the whole area, so that the cable TV signal quality is always in a good state.
Customer service: customer first, caring service, improve maintenance efficiency. Everyone in our operation and maintenance department wants to change their previous ideas. We should base ourselves on the present, recognize the present situation, face the market, provide good services, find users with our technology, acquire users with our quality, retain users with our services, and consolidate the market with our image.
Our service is in place, the signal quality has been improved, and we have truly communicated with users and won their trust. Then next year, we will gradually reduce user complaints.
I believe that the task of 20__ will be successfully completed only if we are down-to-earth and pay close attention to implementation.
The second personal summary essay on operation and maintenance in 2020
Looking back on the past year, under the leadership of the leaders of the city and county work areas, some achievements have been made, but there are also some shortcomings. The operation is summarized as follows:
First, study hard new knowledge, master new equipment and improve business skills.
My unit is a substation that has just been built for 2 years. Office facilities and living utensils are complete, and I have the conditions to envy others' life and study. Since entering 1 10kV substation in April, 2065438, under the guidance of the leaders of cities and counties, efforts have been made to change the previous working modes and methods. From a self-attitude of doing one's own job well and having nothing to do with others, through continuous learning and exercise, it has gradually changed into a new collaborative office model that helps each other and completes and improves together. I remember that at the beginning of the station operation, I still learned the theory and operation method of equipment at sunrise and sunset every day. I am always in initial contact with 1 10 kV substation equipment, and I often feel invisible work pressure, which is eating me up, using the tone that the leaders of the city work area are worried about depression. And this also deeply inspired me to learn business knowledge more consciously.
Until one day last year, when I almost forgot all the business knowledge in my mind in the idea of trouble-free new equipment, I suddenly received the operation instruction of 1 10kV624 line for power outage maintenance. In the tone that the leaders of the city work area are still worried, I face it with correct accident handling methods and operation steps. After the default treatment, at the other end of the long telephone line, I seemed to see the leaders look slightly relaxed.
Second, based on this position, give play to party member's leading role.
As a grassroots substation party member, he is dedicated and loyal. In maintaining the purity of the Party and ideology, we can only love the Party, the company and the company by strengthening the cultivation of the awareness of safe operation of substations and the implementation of the established system management, serving the people well and promoting the all-round development of substation operation and maintenance. Over the past year, I have taken the initiative to study the party's principles and policies, strengthened the cultivation of party spirit, further improved my political consciousness and working ability, and played an exemplary role in performing my duties. Create a harmonious working atmosphere in the company's grass-roots sub-stations, be brave in taking responsibility, and fully reflect the excellent value of party member.
Under the new situation, many years of work in grass-roots substations have made me deeply understand the tasks faced by the company and the power grid development during the peak summer. From the challenge of the post, I always set an example everywhere, and fully reflected party member's execution and practice with practical actions. Over the past year, I have defined the time period, place, personnel and work requirements, carried out temperature measurement and special inspection, including equipment overheating tripping, line sag drop, etc., and comprehensively carried out state inspection and testing of substation equipment. Effectively prevent equipment accidents caused by inadequate inspection and maintenance of substation equipment. Through hard work, under the strong guidance of the leaders of the two work areas, the power supply work during the peak season in summer has achieved satisfactory results and effects.
