The performance index is also a key factor with the increase of heating enterprises' scale and years of operation. In particular, the seasonal characteristics of the heating industry are obvious. Many heating enterprises have a very short charging period. In many cities, heating enterprises need to handle thousands or even tens of thousands of charges a day in peak hours, plus integrated services such as network access, shutdown reporting, reheating, switch on and off, and query, The business system is heavily loaded. Many charging business halls have long queues in the busy season. In this case, if the software performance and stability have problems, it is easy to have small group events. Therefore, the charging software has also made some definitions on the performance indicators of the Heating Charging Management System (200000 households, system response requirements under the condition of ordinary desktop solid state disk): normal page query operation: 0.2 seconds. Charging business operation: 2 seconds (query/charging/refund/shopping cart/stop reporting/reduction/invoicing, etc.). General report query: 6 seconds. Complex report query: 15 seconds. Special report and batch operation: set up requirements according to the actual situation. The function and performance of the product quality Heating Charge Management System is visible.

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.

Considering both speed and security, the platform has made a set of deployment plans. The environment is deployed in the way of VMware virtualization. Five servers form a virtualized private cloud platform, allowing any two servers to fail without affecting the use of the system. Each server is equipped with six 1.2T enterprise hard disks, five of which are interconnected with other servers through 10GbE optical fibers to form a disk storage pool, In addition, two 400G high-speed solid state disks are equipped as cache disks to improve data reading and writing efficiency. For software deployment, we use the tomcat cluster and load balancing deployment mode. Whether it is a toll system or a customer service system, Apache is used as the cluster manager for each service, and multiple Tomcat servers are built under it. This can ensure the stability and security of the system operation, and can also be switched without feeling when the system is updated and upgraded. By the middle of June, we had built 8 virtual servers and 100 virtual desktops on the virtual machine. Four of the eight virtual servers are bank front-end computers, and the other four are application servers, which are respectively the application server of the charging system, the application server of the customer service system, the database server, and a standby server. The next step is to install the virtual desktop. We spent some energy on this link. Yes, yes, it's physical strength! Datong Heating has 4 business halls and 10 branches.

Lose everything. Therefore, in the whole project implementation process, building trust has always been an important position for me. On April 7, 2017, at 8:10 a.m., the kick-off meeting of heating charge and customer service informatization project was officially held. A total of 10 people attended, with more participants from Datong Heating. President Wang led the team, Manager Xu of the Customer Service Department, Director Zhang of the Customer Service Department, Director Zhang of the Toll Collection Department, Director Zhang of the Network Information Department, Chief Financial Officer Li, and core management personnel of charge and customer service also participated. The content of the kick-off meeting was not important, but the project teams of both sides met and understood. The leadership of Datong Thermal Power expressed their determination to promote informatization, authorized the project manager and project team members, and let everyone actively cooperate with the demand research and project implementation of toll software. I also elaborately made a PPT to publicize and implement the project related implementation tasks to all project team members of Party A

Shanxi 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.

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.
