The company will carry out its own work. In addition to managing their own organizational structure, personnel, and processes, subsidiaries also need to establish a number of personalized management models: 1. including their own maintenance of basic information such as residential quarters, heat sources, heat exchange stations, and basic categories; 2. The heating policies in different regions are different, and each subsidiary needs to maintain its own corresponding billing strategy; 3. Each subsidiary can use different methods of issuing bills, including self printed receipt invoices, tax controlled invoices, tax controlled electronic tickets, etc. Each subsidiary of business approval management can independently configure business processes, such as exemption approval, suspension approval, forced suspension approval, area adjustment approval, reheat approval, and network access approval. The process supports hierarchical approval of subsidiaries and groups. Personnel at all levels of statistical analysis can only browse and operate the data range of this level; Group headquarters can view real-time business data and operation data of all subsidiaries in real time for comparison and assessment; Provide rich reports and charts to show the overall operating data of each subsidiary and group.

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.

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.

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.

It is hard to avoid errors. Besides, it is not easy to check the amount of more than one billion yuan to the difference of one yuan! I only remember that we were very happy and even excited that day. The hardware part of the hardware entry into Datong is also a highlight. The entire platform involves many hardware and is deployed in the way of VMware virtualization, including servers, firewalls, switching equipment, office computers, high tempo meters, printers, all-in-one computers, televisions, etc. One of the core switches is worth 200000 yuan, which really refreshes my three perspectives. On May 18, the core server hardware arrived.

Qianxi wisdom Heating charge system software 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.
