In 2xx, the company and the group company set up the OA platform and set up the information department, and I was responsible for the management and maintenance of the OA platform. During my 2xx years' work, with the guidance and care of the leaders and the support and help of my colleagues, I have improved my skills accumulation, work experience, problem analysis and problem solving ability, but there are still many places to accumulate and learn. The professional and technical work in 2xx years is summarized as follows:

1. Ideological and political aspects

I have a strong sense of professionalism, responsibility and mission, and love my job. Over the years, I always put learning in an important position, worked hard to improve my comprehensive quality, studied professional skills with an open mind, and successfully fulfilled all the requirements of my post responsibilities. I always demanded myself as an excellent grass-roots technician, standardized myself, abided by national laws and regulations, and never did anything that violated the law and discipline, and did what a qualified citizen should do.

II. Professional technology

During my work as an assistant engineer, I was responsible for the maintenance and transformation of the factory office network, and at the same time, I was responsible for the daily maintenance of its data communication with the production network and integration with the OA platform of the group company.

when these three networks are interconnected for communication, the difficulty is the security of wiring and communication. First, solve the wiring problem independently. Through consulting materials and communicating with other related technicians, the scheme of integrated wiring is introduced. The earliest Ethernet was built with bus structure. Although the construction method was simple, it would be very difficult to troubleshoot and upgrade the network once there was a problem. Because the problems and changes in any node may affect the operation of the whole network. In this case, through argumentation, the concept of integrated wiring is introduced, and the whole network is divided into six subsystems. According to the actual situation of the company, the six subsystems of integrated wiring system are analyzed as follows:

1. Workspace subsystem

It is an independent area where terminals need to be placed, that is, a workspace, and the workspace system consists of information sockets of horizontal wiring system extending to connecting cables and adapters at workstation terminal equipment. Generally speaking, a public office is a working area, and the terminal adopts IBDN pressure-connected super-five modules and panels, which is convenient for voice and data exchange. Horizontal subsystem: This subsystem consists of the information socket used in the work area, the distribution cable from the distribution equipment to the information socket, the floor distribution equipment and the jumper. Sub-package the smart box in the company floor to ensure the separation of voice and data, and make internal and external connections in the smart box for network transmission through the data port.

2. Trunk (vertical) subsystem

This subsystem should be composed of wiring equipment and jumpers in the equipment room, and connecting cables between equipment and wiring rooms on all floors. The signal is introduced from the group company through optical fiber, and then led to the computer room through optical fiber transceiver and optical fiber, and connected with the access network to realize networking with the Internet.

3. The equipment room subsystem

is the place where equipment is set up for network management and managers are on duty. Set the company's central computer room (information department) as the equipment room subsystem.

4. The management subsystem

is set in the room of wiring equipment on each floor and consists of wiring equipment and input/output equipment in the handover room.

5. Building complex subsystem

The company's electrical main control room (signal input) and the company's office building (signal output).

according to the division of labor, changes in each system will not affect other subsystems. And it will be relatively easy to troubleshoot network problems. Therefore, the most important function of integrated wiring is to facilitate management.

second, communication security. The most fundamental problem to be solved is data filtering, installing anti-virus software and firewall. The most critical problem of secure communication is the access of production network DCS. In order to solve this problem, a hardware firewall is installed, which effectively prevents the functions of CF (content filtering), IDS (intrusion detection), IPS (intrusion protection) and VPN.

summarizing the professional and technical work in 2xx years, although I know that I have made some achievements and progress, I also know that I still have some shortcomings, such as my theoretical foundation is not solid, my business knowledge is not comprehensive enough and my working methods are not mature enough. In the future work, I will strive to do better, strengthen concept learning, accumulate work experience, constantly adjust my way of thinking and working methods, participate more in the construction of the factory, hone myself in practice, and become the backbone of the department and project team. 221 Summary of Electronic Engineer's Work Fan Wensan

Time flies, and he has graduated for three years in a blink of an eye. I have been working in xx Company for more than two years. Due to the demand of work and improving my technical level, I entered the technical department of xx Power Distribution Equipment Co., Ltd. to study and work. I have worked in xx Company for more than two years and have grown into a qualified electrical engineer.

when you first enter the company, you must go to the electrical workshop for an internship. During the period, I was mainly familiar with the products and laid the foundation for future design. After the internship, I officially entered the technical department.

at the beginning, I was mainly responsible for designing some small orders, such as small boxes, pgl, ggd, and some relatively standard xgn36(15)-12. Usually, the number is several, or the order with an output value of less than 1,. During this time, I studied with the chief engineer and the old engineer, trained professional skills and basic knowledge at night, and then tested the learning results on the order. I was deeply impressed and influenced by my study and work during this period.

Some relatively standard engineering orders, such as star delta step-down start, full-pressure start, auto-coupling step-down start, motor forward and backward rotation, etc., were all studied in school, but they were not impressed at that time. After doing these motor control projects, the previous theory and practice were combined to design control products with their own style. Such as temperature control box, gas control box, street lamp control box and so on. The main problem encountered by this kind of products is the arrangement of components, which directly affects the external dimensions of the box or cabinet and the direction of cables. Once you are not careful, users will encounter a lot of problems during installation and use. When making this kind of products, we must be careful, go to the site to communicate with customers, and after understanding the customer's intentions, it is best to design a general layout and outline drawings for customers to confirm.

with the growth of experience, we began to make a relatively large set of gck, usually dozens or hundreds, and the output value usually exceeded 5, yuan or even one million yuan. The main functional units are: metering cabinet, incoming cabinet, capacitance compensation cabinet, feeding cabinet, municipal power generation conversion cabinet and contact cabinet. Basically, every two years, xx Power Supply Bureau of xx Power Grid will put forward new requirements for metering cabinets. Usually, within one month of putting forward new requirements, the problems are the most. For example, in the past, transformers with 315kva and above were required to be equipped with two sets of current transformers, an active meter and an electronic meter, and low-voltage charging was adopted. Now, for a group of current transformers and an active meter, it is necessary to install a 1kv high-voltage metering cabinet and adopt a high-voltage charging method. If we don't pay attention to this problem, the goods will not be connected to the site, and will not pass the acceptance. The amount of on-site renovation work is very large, and it will bring negative effects to the company.

the commonly used feed unit of gck is the drawer cabinet, which is an advanced cabinet type in China. It is usually necessary to pay attention to whether there is a "non-fire-proof load" in the load, and such a load must be cut off in case of fire to prevent the accident from expanding. Usually, a dc24v fire-fighting shunt coil is added to the molded case circuit breaker to realize tripping. Many people interpret it as "not a load that must be protected by fire protection", which leads to the wrong position of the trip coil and jumps off some fire protection loads, such as fire fans and fire pumps. In fact, fire protection loads cannot be cut off. Once there is a fire, it will lead to a more serious fire. It should be understood as "non-fire-fighting load that must be protected".

after that, we will start to make high-voltage cable distribution box dfw-12 and high/low-voltage pre-installed power station ybp(m), and then go to xgn15 ring network cabinet, kyn28a-12 middle cabinet, and more complicated plc and frequency conversion control cabinet, direct current screen (gzdw) and signal screen; From simple to complex; From small projects, small quantities to large projects, multiple large orders; With the increase of design projects and experience, we can master the system schematic design of various cabinets, the design of secondary control wiring diagram, including various non-standard motors, fans, fire control boxes, and various dual-power, multi-power three-in-one and five-in-one systems skillfully and rationally. At the same time, I am very familiar with the structural characteristics of various cabinets. I have been responsible for the design of xx Real Estate (xx Villa), xx Municipal Party School, xx Electronics Factory, xx College of xx College, xx Paint (xx) Co., Ltd., xx Grain and Oil Center Electric Room, xx Ecological Park Office Building, xx Residential Area, xx Vocational and Technical College, etc. Through the cooperation with Party A and weak current designer, we have a more comprehensive understanding of the design and operation of power system. During these years, I followed the chief engineer to participate in the accident analysis of vertical bus terminal arcing in xx Brewery, the short-circuit fault analysis of 1kv outdoor cable distribution box in xx Power Supply Company, the treatment scheme of xx sand pump factory affected by harmonics, and the noise treatment of large current cabinet in xx shoe factory, which deepened my understanding of theoretical knowledge, better integrated theory with practice, deepened my impression, got a new understanding of products and broadened my horizons.
