Plant Monitoring scheme

In recent years, with the popularization and deepening development of the network in China, the enterprise information construction is deepening, all walks of life have accelerated the construction of the information network platform, most units have or are laying the enterprise internal computer LAN; At the same time, the web also provides a good platform for advanced emerging applications. In modern enterprise management, the improvement of safety protection, monitoring and control system has played an increasingly important role, and to build network system with combined monitoring system not only can reduce the engineering * degree of transformation period, at the same time avoid the repeated input of capital and improving the efficiency of the network resources.

The factory has large scale, complex production and management departments, and high safety factor requirements. In many production workshops, airport runways, special outdoor places and functional departments to realize the combination of on-site monitoring and production command and dispatch, will greatly improve the intelligent management level of the factory.

1. User demand analysis

(1) One monitoring * to complete the centralized monitoring and management of all the monitoring points in the factory;

(2) The whole monitoring system adopts two levels of management, that is, monitoring * and functional department monitoring

(3) The monitoring equipment can directly collect the signal through TCP/IP protocol in the LAN/WAN transmission;

(4) Some cameras and nodes on the network constitute relatively independent information individual groups due to the distribution of buildings and sites;

(5) Monitoring * Real-time video display and uninterrupted digital video storage can be carried out on the TV wall or projector for the selected monitoring point, and users can retrieve and replay the stored historical image data according to the time.

(6) The cameras at each monitoring point can be triggered according to different external conditions to realize alarm and self-start for on-site recording to achieve disaster recovery and backup.

(7) According to the particularity of the factory, the whole system should have perfect safety performance and strict permission setting.

(8) According to the requirements of high-performance compression algorithm, clear and smooth sound

(9) Make full use of the original network resources of the factory, reasonably allocate the network load, and minimize the repeated investment of capital.

(10) Ensure that the existing planning and construction have good scalability and secondary development.

2. System requirements:

(1) Stability of the system

Factory network monitoring system plays an important role in the management process of enterprise modernization. All audio and video data, ERP data information and other network activities are completed through this system, so the security and stability of the system is very important. We should take this system requirement into full consideration in the design stage. Through the purchase of mature and stable network products, monitoring products, supporting equipment, strict and standardized construction process and scientific management system to ensure the stability of the whole system.

Easy maintainability

Easy maintenance of a system is a very important indicator of the system, for a larger system, unified planning, structured design, equipment, equipment, software as far as possible unified procurement, unified management, selection of qualified suppliers is the key to ensure easy maintenance of the system.

comprehensive

According to the actual requirements of the factory, the current enterprise resource management information system (ERP) has been running normally through the computer network, and the network video monitoring, security alarm and other systems required to be realized now also need to use the computer network platform of the factory (can be properly upgraded on the existing basis).

scalability

The system requirements of the factory are also gradually improved, which requires that the design of the system should leave sufficient room for expansion, which can be easily completed when the factory needs to expand or upgrade the system.

security

The factory as a special enterprise, security, confidentiality work must be considered. In the process of data transmission in the network, in order to prevent information from being eavesdropped or intercepted, the data must be encrypted. At the same time, we also need to consider whether the network operating system inside the network is sound, whether to ensure a perfect user security mechanism and can defend against internal and external malicious attacks.
