Guanling Easy to charge Natural gas charging software Plan and implement the requirements, make everyone clear about the work to be done in the future, and make psychological preparations. The kick-off meeting was relatively smooth. I could feel the importance of Party A's leadership, the urgency of the business department's demands for the new system, and the support signal from the network department. Later, after the kick-off meeting, I helped us adjust the network environment of the temporary office, and we were directly stationed. After the kick-off meeting of demand collision, the project research begins. Party A has arranged the office chair, power supply and network for us on the first floor, and we can start work there. This is efficient! It's opposite the office.

In such a period, how can we find the right way? First of all, let's look at the macro trend. If you don't understand, you can look more at the road of Japan, or look at the industrial driven national model of Germany. In countries like Japan and Germany, at present, they are typical of giving up real estate and focusing on industry. People distribute wealth through industry or labor, so the gap between rich and poor is very small, The social contradiction is very small and the productivity is very high (China currently relies on real estate and finance to distribute wealth, which is more than that of previous landlords who rely on rent for nothing). Extensive development has come to an end. The previous methods of winning by volume, speed and scale may be outdated. The future competition depends on core competitiveness. In the shrinking market, everyone is shrinking their business boundaries and sticking to their own barriers.

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.

The challenges are huge, so each heating enterprise can expand the heating site more flexibly and effectively by dividing the land for management. However, as the country has changed from extensive to refined development, and the heating business in various regions has a lot of similarities, those large heating enterprises with strong capital and advanced management ideas have begun to expand everywhere. At present, many powerful heating group enterprises have been born in China, among which one group enterprise just merged some local small and medium-sized heating enterprises, with centralized areas and similar management, and relatively simple group management and control; Another type of group enterprise is to expand its business to all parts of the country, which is far away and has different heating management and policy regulations, leading to great challenges in group management and control. In any case, the group headquarters should be able to keep abreast of the situation of each branch at any time to achieve "decentralized operation and centralized management".

Then on April 23, the bank collection kick-off meeting hosted by us, organized by Datong Thermopower, was held in the conference room on the fourth floor. The participating banks were Bank of China, China Construction Bank and Datong Bank. At the meeting, I introduced the docking method and schedule of our project, mainly to promote the bank to start the work as soon as possible and complete the docking and online of agency fees as soon as possible. At the meeting, all the banks expressed their willingness to actively cooperate with this part of the work, but the schedule was a little tight, after all, the process of the bank was slow. In fact, they later confirmed their words with their actions, because none of them went online within the expected time, which should be regarded as Datong Bank, which completed the online before the official charge. In the process of bank docking, due to the tight time in the later period, we often worked overtime. From network debugging to service deployment, we got a bank in two days on average. During the technical joint debugging, we Zhang Gong responded one-on-one. Before the online test, we made a detailed test case based on the classification of Datong thermal business types, with a total of 41 types and more than 120 variable parameters. This case provides an important technical guarantee for the stable operation of bank collection in the future. Performance test The performance test work of Datong Thermal is indispensable. In the past, we

Mr. Zhang is responsible for the accuracy of the charging data and statements, Mr. Yang, the implementation engineer, is responsible for the mobile inspection of the business halls in the west, south and north cities, another person is responsible for the operation of the customer service system, one person is responsible for the detection of the telephone and call center, one person is responsible for the general of the server and network, and then I am responsible for resource scheduling and replacement. A total of eight people are in full support on the site. On September 3, after two days of stable operation of the project, some problems gradually surfaced. There were two serious problems: one was the failure of e-ticket signature, and the other was the printer's overheating and downtime. First of all, the issuance of electronic invoices is under the unified control of the national tax system, so each invoice must be signed and sealed by the National Tax Bureau system. Only after the signature and seal are successful can it be regarded as successful.
