The project can be launched at any time when the problem is repaired! At 8:48 on August 31, a 2175 yuan heating fee entered the system and an electronic invoice was successfully issued, marking the official launch of the Datong Thermal Power Project! Yesterday, I discussed with Director Xu to let the system go online one day ahead of schedule. If something happens, we can still deal with it that day. The fact proves that our decision is wise. On the morning of September 1, the business halls had not yet opened for business, and the people outside had lined up. I didn't expect the hot users of Datong to pay fees so actively. Fortunately, we had "practiced" for a whole day yesterday, so we were full of confidence in this scene today. Not to mention, there were a lot of problems found after a day of trial operation yesterday, which were mainly manifested in printer compatibility problems, unskilled operators, occasionally stuck on the electronic ticket page and did not respond, continuous photo taking and error reporting by the high timer, etc. For the problems that occurred yesterday, we arranged engineers to go to the business hall with many problems for assistance and guidance today, We explained on the spot when we were not skilled in business. When the printer and beat meter did not work, we demonstrated and debugged on the spot. When the electronic ticket was stuck, we taught how to reopen it and contacted the Hangxin engineer in the head office for troubleshooting. In a word, we successfully completed the launch in the real sense.

The implementation must be carried out in accordance with the customer needs and contract agreements in the early stage. The charging software has set a boundary for the implementation work, which helps our engineers and customers reach an agreement faster and build trust. Training arrangement: a large-scale centralized training for 1-2 days, providing documents, videos and examinations; Follow up targeted training and coaching. Data migration: the primary data migration is completed by the toll collector under the guidance of Excel provided by the toll collection software; Advanced data migration is led by charging software, and finally verified by heating enterprises; WeChat public account operation: Toll Ease software is responsible for business docking, such as query, payment, repair and suspension; The heating enterprise arranges special personnel to be responsible for the backstage operation, mainly including customer messages and news releases. Data confidentiality: Toll Ease Software guarantees not to disclose Party A's data to three party organizations or individuals without Party A's authorization. Fault recovery: If the system cannot be used due to virus or other reasons, the system recovery shall be carried out, and the recovery data shall be subject to the new data available. Repair services do not include network environment processing, server operating system reinstallation, computer maintenance and other operations unrelated to business systems. The practice background of the group version of the heating charge management system is that "long hours must be combined, long hours must be separated", which is also very applicable in the heating industry. In the period of large-scale urbanization, it involves projects, funds, management, talents, etc.

During the implementation of the project, we also contacted and learned about various heating network automatic control manufacturers in the heating field. Therefore, although we can't say that we are heating professionals, we can also dig deep into the field of operating charge management. But why is it so difficult to do heating management software? I think the main reason is that the industry itself is lack of norms and standards, and cannot be quantified as water and electricity. Heating regulations are basically one policy for one city, and cities interpret and implement similar policies and regulations differently. Without standardization, the projects have become customized and the customers have become experimental fields without specialization. The charging software is carrying the banner of standardization and specialization of heating management software in such a difficult situation.

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.

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.

Yunnan wisdom Toll software The year was the year when the global return on assets was poor since records began. Most fund managers were proud to lose less than 5% in this year; Some people say that China's economic L has not reached the end, and no one knows how long the horizontal line will be after reaching the end; In the past few months, the President and Prime Minister of the People's Republic of China also rarely expressed on official occasions the economic downturn and the situation was stormy; The Sino US trade war continued to ferment. In fact, the common people's cognition often lags behind the environment. It can be said that the country has started macro-control as far back as 2015. At that time, a small number of industries began to feel the chill first. I remember that when companies recruited in those years, many of them jumped from shipbuilding, machinery and other industries to the IT industry. The IT industry in China belongs to the service industry and also has high-tech attributes, so it is less and slower affected by the economic crisis. But under the overall depression, can the IT industry be independent? Since the reform and opening up, especially after China's entry into WTO, foreign capital has brought technology and experience to China at the same time.
