1. System Overview
In recent years, with the popularization and deepening development of the Internet in my country, the information construction of enterprises has continued to deepen, and enterprises are gradually turning to the important stage of using the Internet and computers to centrally process a large amount of data such as management, production, sales, logistics, and after-sales service. All walks of life have accelerated the construction of information network platforms. Most companies have or are laying computer LANs within the enterprise; at the same time, the network has also become a good platform for advanced emerging applications. In modern enterprise management, due to the increase in security protection requirements, the monitoring system plays an increasingly important role. Combining existing and to-be-built network systems with monitoring systems can not only minimize the transformation cycle of the project, but also avoid repeated investment of funds and improve the utilization rate of network resources.
In the process of modern enterprise development, in addition to establishing a comprehensive, scientific and effective management system and incentive mechanism, it is increasingly necessary to establish a complete factory video monitoring system. The factory area is large, the production and management departments are complex, and the safety factor requirements are high. The combination of on-site monitoring and production command and dispatch in many production workshops, logistics channels, special outdoor places and functional departments will greatly improve the intelligent management level of the factory. Therefore, installing a network video surveillance system in the factory has always been one of the essential management measures for many manufacturing companies or factories. Dongguan Weituo Industrial Co., Ltd. provides a full range of professional factory video surveillance installation system equipment and has rich experience in designing factory monitoring system solutions.
2. System Analysis
The preliminary design of the factory video surveillance installation should meet the performance of existing resources and network requirements. The construction of the front-end video acquisition subsystem and the monitoring center video management system should meet the performance requirements of the Ministry of Public Security's "Opinions on Carrying out the Construction of Urban Alarm and Monitoring Technology Systems", and strive to ensure stable system operation, reliable data storage, and regular archiving of video data.
First of all, the video surveillance system should ensure the personal safety of staff in the factory and public activity areas, the property safety of production equipment and other important facilities, prevent man-made sabotage activities, and obtain the process video of the incident as soon as possible after the accident occurs, so as to provide strong evidence for timely handling and accountability. This is the basic functional requirement of video surveillance. Another important aspect is that the video surveillance system can play an auxiliary role in the daily production process of the factory and realize the unattended production line.
According to the requirements of government departments and the relevant provisions of internal safety production management of enterprises, and in accordance with relevant national standards, combined with the needs of factory video surveillance, the network video surveillance system functions are formulated to achieve the following goals:
1) Video acquisition function: The front-end video acquisition system acquires video and compresses and encodes it according to the transmission requirements, and converts it into an information format that can be transmitted through the access gateway and meet the transmission on the digital exchange network.
2) Video transmission function: The compressed and encoded video information is transmitted in the factory private network according to the workflow, and the transmission network system at all levels is formed according to the security management authority. At the same time, it can meet the management needs of the monitoring system, transmit to the upper system and store it.
3) Information processing function: The systems at all levels process the received video information according to the video classification and attribution, and process the called storage information.
4) Video storage and backup function: The monitoring center server should store video information and system logs. The historical data information stored and backed up can be played back in the network system according to the authority.
5) System control function: According to the authorization, the control command issued by the network user is transmitted to the front-end system, so that the monitoring center and the authorized user can call and control any monitoring image of the front end.
