Just matched with China's demographic dividend, China's economy took off rapidly and foreign trade developed rapidly. Chinese enterprises, especially private enterprises, have accumulated a lot of wealth in the past few decades, which could help our country increase investment in R&D and gradually move towards the road of becoming a powerful country through science and technology. However, the reality is cruel. With the bloody plunder of real estate and capital, China's real economy suddenly becomes powerless, Most small and medium-sized enterprises become moribund under high land rent costs. Everyone knows that when the economy is bad, the first thing to affect is the short cycle agriculture.

This is what I expected. On August 16, the training finally came to an end. These days, the brothers and sisters of Datong have listened attentively and enthusiastically. I think an enterprise is a dynamic enterprise if its employees have a positive attitude towards work and are willing to accept new things. We are willing to serve them. Although it has been a little hard these days, we are very pleased. In the following days, Director Xu allowed everyone to get familiar with the system and perform simulation exercises. At the same time, we also printed the User Manual for distribution to help everyone learn and consolidate the system operation. By the time the system went online, everyone's understanding and operating proficiency of the system had reached the standard, and some people even exceeded my expectations. It was great! The first few days before the project was launched, it was like darkness before dawn.

There has never been such a big fight on other projects, because the magnitude of data cannot be reached. This time, we have organized a special team to be responsible for the performance test and optimization of Datong Thermal. The test is divided into performance troubleshooting stage and stress test stage. Performance troubleshooting stage: test all the functions of the system according to the test cases, find out the functions that lead to the increase of system resources and slow response, record them, and optimize the performance problems exposed in this stage. Stress test phase: perform concurrent stress test on common functions. In this phase, we focus on several main performance indicators: response time, throughput, and system resource consumption. First, the common functions that need stress testing are determined and the test scripts are sorted out. Determine the test concurrency of 5,10,15,30,50 according to the actual use of the customer, and simulate 5010015030500 people using the system at the same time. Lock the functions with performance problems according to the concurrency test results, and determine how to allocate the resources of each virtual machine and how many Tomcat clusters to create. On site training At the beginning of August, Director Xu called me to the office to discuss the system training.

Tianjin Easy to charge Heating charge system software Task! After half a year's hard work, it finally becomes shining today! The leaders of Datong Thermal Power Business Department were also satisfied with the effect of the project launch. The reconciliation and financial statements of the day were very accurate, and everyone was very happy. A feeling of "see the sun through the clouds, and see the moon through the clouds" slowly spread in our hearts. On site support Since August 25, I have successively applied to the company for resources to be sent to Datong Thermal Power. The purpose is very clear, which is to protect the stable operation of the project. By August 31, our team was in place: Yang Gong, the R&D engineer, was responsible for the rapid handling of software emergencies, and Han Gong, the implementation engineer, was responsible for the stable operation of Huadu Business Hall and the charging system.

The electronic ticket issuing of Tongrui will occasionally fail to sign, and once failed, it will last for more than 10 minutes. Although it is not a long time, the hot users waiting outside will become anxious. After analyzing and testing the system interface, we determined that it was not caused by the charging system, so we suggested Director Xu contact Hangxin Company for troubleshooting. Yang Gong from TravelSky responded promptly. He arrived at the thermal power company after a while. After analysis, most of the data upload failures were caused by network congestion. After network testing with Datong Thermal Power Information Office, it was basically determined that the problem was China Unicom's network. After the check out in the afternoon, Zhang Chu of the Information Department contacted the telecommunications company to switch the private line network from Unicom to Telecom. After that, although the signature failure will also occur, the frequency of the problem is greatly reduced. It seems that the selection of network operators really needs to be adapted to local conditions. Another two points: Datong Thermo's hardware procurement standard is very high. In order to make it easier for individual people to accept electronic invoices, the printer is purchased by HP color laser printer, which is not only expensive but also expensive in consumables. This is the first time I have seen Thermo adopt color printing. But the problem is that the effect of color playing is good.

The project department immediately received the news of winning the bid. As the project implementation manager of this project, the feeling of joy was fleeting, and the responsibility that followed was heavy. But when I saw that the colleagues in the R&D department were all working hard, with high morale and confidence, I was relieved of most of them. Calm down and check the basic data of Datong Thermal Power. It is learned that the network area of Datong Thermal Power is 72.6 million square meters, which is a national large first-class enterprise, with 10 heating branches, 1 maintenance and repair branch and 5 customer service points. As of 2017, the company has laid a total of 875 kilometers of primary heating pipe network, with a central heating area of 58.6 million square meters for cogeneration. For more than a decade, 897 coal-fired heating boilers have been removed.
