Since the company in August 1999 I was awarded the title of the technician to the present,has been four years time.In these four years,I have been in the operation department,by virtue of their own efforts and leadership to help,from a main duty officer promoted to the duty chief,and was promoted to the post of assistant.During this period,I have our first station of the system have a better understanding and awareness of some of the various types of accidents have a certain degree of independent analysis and processing capabilities,a technician to do a good job duties.
My major in the school of thermal and automation control professional,but in the first station to run our work is most in need of heat,electrical and other aspects of knowledge.This is for me a new challenge,but also the need for continuous learning to improve,so that their professional skills can be fully developed.So,I got some books about these areas,targeted to our system of learning,but also ask some of the old master and professionals,ask them to show up preaching.Through their own efforts and the help of colleagues,finally work pays off,my professional knowledge and professional skills have been greatly improved.
But I have a lot of knowledge about the thermal aspects of our system and are particularly interested in it and have a thorough understanding of it.While at the same time learn from their own,but also assume responsibility for preaching to other operational personnel.Our company's hot water network project is the use of computer monitoring system to achieve hot water production and operation of the comprehensive monitoring of the data.Its main components include the controller,input and output modules and monitoring stations.Our company has 18 sets of SCAN3000 / S9000 distributed control system (DCS),which has the functions of hot water network operation loop control,data acquisition,data communication,centralized information management And operation display functions.It is equipped with two S9000 controllers,and another 12 single-loop controller (Honewell UDC3300),as the control loop redundancy controller and emergency hand terminal.UDC as a backup hand-held device can DCS in the event of failure,the control loop to control.With easy to operate,programmable,high stability characteristics.
DCS system and UDC can achieve between the non-disturbance switch,to ensure the stability of the system operation.S9000 controller through the DVC communication port of the DMC communication circuit and single-loop controller to achieve communication;through the MGTSTA communication port and the system monitoring station communication card connected.With these control systems,usually a variety of parameters of the regulation and personnel labor will have a multiplier effect.These control systems are made up of measuring elements (temperature transmitters,pressure transmitters,differential pressure transmitters),control elements (S9000,UDC),actuators (regulators,etc.).Control flow is such that the scene collects data from a meter,the transmitter sends 4-20mA signal to the S9000 (that is often said DCS),1-5V signal to the UDC.And then issued by the S9000 or UDC 4-20mA signal (UDC series with 250Ωresistor,1-5V signal to 4-20mA signal) to adjust the actuator.In this process,the instrument's power supply from the two Siemens 24V DC power supply (the two power supply each other spare),the power to the distributor,and then by the electrical distribution to a primary meter power supply (the middle of electrical distribution in order to meter repair,Will not have a short circuit,and damage the DC power supply).DCS or UDC receives the signal that is displayed on the CRT or UDC own screen.DCS or UDC control signal to the impedance converter,distributor,the isolation module or isolated relay relay to the executive control.
Isolation module is through the analog signal,that is,continuous control signal 4-20mA,such as the valve opening,level control;and isolation relay is the switch signal to the DCS,such as temperature switches,pressure switches and pumps Start,stop state,etc.(plus isolation module,isolation relay is to isolate strong signals,so as not to S9000 in the loop control card burned).
During the shift,as a monitor,I assume the responsibility of the entire hot water network security and economic operation,the spirit of a high degree of concentration during work,leading the team members carefully adjust the parameters,careful analysis of the data,sum up the law,Found that equipment defects and risks,to prevent the expansion of the accident.Not only to ensure the safe operation of the hot water network,but also to the economic operation.In some parameters and equipment anomalies,can do a timely analysis,find out the reasons and report,with a certain degree of independent analysis.Usually go to work,often carefully study a variety of professional knowledge and operating procedures,and can often do a good job in the minds of various accidents expected.In the first station when various types of accidents,can be accurate and decisive for processing and scheduling,and quickly restore the normal operation of the system.During the operation of the Office of the Ministry of Operations,I not only assume the daily operation of the Department of Management,logistics,but also bear the auxiliary operational personnel to make the safe and economic operation.And the sector leaders to make the data with the economic analysis and load forecasting,to participate in the analysis of the accident,the system of technological transformation and so on.Such as: the first stop CRT display large network backwater pressure value is often high during the day and often need to turn on the water,after a few days of observation statistics,have this phenomenon,self-examination first station no problem,the analysis may be a user station exists Leak,the pressure during the day when the pressure is greater than our pipe network pipe leakage to our network.

I have benefited a lot from this year's hard work and constant learning since I had been working in July of XX years ago.Here it is necessary to summarize the gains and losses over the past year,to carry forward a good place to improve the inadequacies of the review of the road can be better to see in front of the road.
Character is a prerequisite to determine the value of a person.Not a good moral character,everything else is empty talk.So this year I insist on regular study of Marxism-Leninism Mao Zedong Thought,to improve their own ideological consciousness.The formation of their own correct outlook on life values.But also actively participate in the school organization of various learning political activities,self-taught a lot of social philosophy,which are very helpful to me,I also worship a great charisma,and has been trying to do it themselves.All in any case,I have not forgotten political learning,and to the moral demands of their own.Usually and teachers live in harmony,work together,learn together,and common progress.At the same time do not forget to help others,helpful people not only can cast a noble character,but also will get a lot of their own interests to help others but also to help themselves.
"Learning for the teacher,behavior world Fan",is that every teacher should follow,is a norm of teacher behavior.This year,I pay attention to their own moral behavior,and strive to give students a good example.Because high school students are in a special stage of learning: the beginning of contact with society,the role of people in society began to gradually understand,this time students can easily imitate the behavior of adults,a lot of bad habits have Many good habits are in this stage to develop,is good or bad with the teacher's words and deeds of the body has a great relationship.This time the teacher is the most direct and easy to learn the object,as a high school teacher,do their own code of conduct for students to establish a good learning model is very important.This is my own requirements.
As a computer teacher,the rapid development of information technology,the rapid development of their own knowledge is very important,do not learn a day,it will lag behind,so since the work,I still continue to learn,did not dare to relax.As soon as I have free time,I will strive to learn information technology-related teaching methods,learning information technology-related technologies.The field of information technology is very extensive,the technology from shallow to deep span is also quite large,a person's knowledge in this ocean is like a dust,in order to better based on society,must continue to increase the depth and breadth of knowledge.This year,I try to expand their knowledge,but also continue to delve into the depth of their own feel a lot of harvest.Of course,this is still not enough,Xuehai knows no boundaries,in the next year,there are more need to learn,and now only sigh too little time,the clock is too fast.
When the teacher for almost a year,although the teaching method is not very mature,but I have learned a lot in teaching.In this year,I served as a year seven classes of information technology teaching,one six classes of vice class,and is responsible for school computer maintenance,electronic reading room management,work is more substantial.I often think about the teaching methods of information technology,the design of teaching methods,and whether this design can make students more receptive.I also understand their own knowledge does not mean that teaching is good or bad,teaching is a meticulous work,but also skilled work.So I think the importance of teaching and research in teaching is even higher than their own learning,and I have been spending more time in teaching and research,not months of teaching and research activities as I learn other teachers experience a good time to actively participate in Each of the teaching and research activities,each event I feel a lot of benefit.As the old saying goes,it is better to delegate to fish than to fish,but it is easier said than done,and it will take some effort.I think teaching students how to learn is the most important,so every teaching,I try to move closer to this,and strive to teach students how to self-study,how to choose meaningful learning.At the same time,also did not forget to knowledge education and emotional attitudes,values combine to cultivate the new century qualified middle school students.
Of course,this year I have a lot of deficiencies,for example,as a teacher,I did not spend more time to in-depth students,students,I think this is not enough,the saying goes,to know ourselves,can only win,Want to better do a good job teaching,students should be in-depth understanding.Also,the lack of new information technology teaching materials.This will be my next year's improvement direction,strive for better in all aspects.
