Project Name: Nanjing Yangtze No. 1 Middle School Standardized Weak Electricity Project
Project implementer: Nanjing Erxun Intelligent Technology Co., Ltd.
I. Project Overview
Nanjing Yangzi No.1 Middle School is located at No. 128 Yangcun Road, Yanjiang Industrial Development Zone, covering an area of ​​42,397 square meters. Some of the buildings are aging. The school combined with seismic strengthening construction to transform the weak electricity systems of Buildings 2, 3 and 4. The construction of the weak electricity transformation includes basic network construction, telephone, monitoring and alarm system, and information center equipment construction. Build a high-performance Gigabit network to meet the needs of school teaching and office; then integrate with the original equipment of the school to build a high-standard, high-performance campus network. At present, the bridge and the dark pipe routing infrastructure are responsible for the completion.
2. Standardization and standardization of project implementation
Safety responsibility system: Erxun implements the responsibility system for production safety, clarifies the responsibility of the company's leaders and all levels of personnel for safety work, and conducts all-person, whole-process, and all-round safety management. The general manager of the company has overall leadership responsibility for the company's safety work; the in charge of the leadership has direct leadership responsibility for the company's safety work; the safety and quality supervision department manages the safety work within the scope of the management under the leadership of the responsible leader; the project manager is the safety production of the project. The first responsible person is responsible for the safe production of this project.
Engineering quality assurance system: The company's current quality system is the general policy and principle that the company must follow in carrying out various business activities, and the quality management and assurance system for project implementation is a concrete embodiment of the company's current quality system. Therefore, it Must be consistent with the company's current quality system. At the same time, combined with the specific needs of the project, establish a practical quality system, so that it can effectively run in all aspects and stages of project implementation to ensure the realization of project quality objectives. In order to implement the whole process of construction, adjustment testing and acceptance of the ISO9001 standard of our company's quality management system for the implementation of our company's quality management system ISO9001 standard, we have established our company's professional quality inspection engineers, technical departments and materials. The department in charge of the department and the quality management department composed of project technology and management personnel are equipped with sufficient and professional quality management personnel and necessary quality inspection and monitoring equipment to strengthen quality inspection and monitoring, and strive to improve the quality inspection and monitoring of construction. The level of specialization.
Engineering construction technology control measures: In order to maintain the integrity of the existing process technology documents, so that it can fully guide the construction implementation, ensure the quality of the project, and avoid confusion, we have a clear division of management business: the person in charge of the system integration department is responsible for the system. Formulate and approve the management of various technical documents and determine the relevant matters; the archivist shall be responsible for the custody, receipt and dispatch of technical documents and the management of technical documents in accordance with this system. Project implementation process The laws, regulations and standard documents we have are: 1. Relevant laws and regulations; 2. Product standards and related management standards stipulated by the state; 3. Relevant quality standards. The working documents include: 1. Drawings and various technical procedures, process cards, work instructions; 2. Process quality list and quality control point list; 3. Product instruction manual; 4. All equipment operating instructions in the company; 5. Equipment Instructions for use; 6. Various schedules.
Third, professional system solutions
Strictly implement the equipment standards set by the state, and fully discuss the needs of the entire project in the early stage. After identifying the basic needs, the professional design team is invited to design. The leaders of the Education Bureau, relevant experts and school representatives have fully marketed the plan. Research and demonstration make the project project scientific, applicable, practical and cost-effective. The application of more advanced technology in professional technology is convenient for the school to use flexibly. Designers with professional design qualifications are designed according to national industry standards and intelligent integrated wiring design specifications. The blueprint design communicates with the user unit at least ten times. The blueprint modifies the twenty-four drafts and finally designs the conformity. The construction blueprint requested by the customer. With reference to the infrastructure-based blueprint construction method, the construction site actively cooperates and coordinates, and under the supervision of the project supervision, the safety, progress, quality and environment of the entire construction site are standardized and managed, so that the whole project achieves high performance and high quality. Standard.
The backbone of the computer network system is connected by multimode fiber optic cable, and the switch to the desktop uses six types of twisted pair cables to realize gigabit to the desktop. The network system not only provides support for existing network applications, but also provides space for wireless systems, information distribution systems, and other systems based on network applications in the future. The access switch uses a full Gigabit managed switch. The computer network system sets security gateway/VPN device, network switching device, server, etc. The firewall is used to prevent external systems and malicious attacks, as well as route NAT to connect INTERNET and VPN functions. The focus of network security is not only to defend against external network attacks. It is necessary to consider how to manage the behavior of intranet users. The video surveillance system adopts a digital high-definition camera, which uses a network cable to realize the fusion of signals and power supply, and adopts a switch of POE technology. The video transmission between the building and the building shares the core of the multimode fiber optic cable in the network system, and the video stream and the network data stream are shunted. The monitoring system is divided between the equipment room and the former teaching building and the post-teaching complex. The after-sales service commitment was fulfilled strictly in accordance with the requirements of the contract and the bidding documents. The original professional technical engineer was invited to conduct product training and application training for the user.
Fourth, project innovation articles
Professional large-scale network management software is used to manage and control all devices, IPs, and terminals in the entire campus network system to achieve "unified network management platform, construction of virtual network management, service application management, service traffic analysis, data center zero configuration, and network services." Campus network application requirements such as automatic orchestration, automatic migration of virtual resources, automatic measurement of IT service level, and improvement of network information auditing, reduce network maintenance time for network administrators.
