Factory monitoring application program
With the development of society and the prosperity of the economy, modern science and technology have been more and more widely used. The use of modern high-tech technical means, through the use of optical fiber network switches to achieve video surveillance systems, real-time, intuitive HD transmission provides a variety of on-site information, to improve the management level, transmission of monitoring data production and equipment operation, strengthen security and eliminate hidden dangers To prevent accidents, it has an irreplaceable important role and is one of the important signs for enterprises to enter modern management; the transmission monitoring data system can not only realize the real-time transmission of people flow and logistics monitoring in and out of the factory area, greatly improving the safety and security of the factory It can also monitor people, things, and things through data transmission to the workshop, production line, and office area, and improve enterprise management level and production efficiency.
The Tianbo solution aims to build a video surveillance system based on optical fiber (IP) network transmission, improve the security and production management level of enterprises by means of science and technology, reduce the work intensity of the management department, and ensure the safety of people, property and materials in the factory area.
demand analysis
Real-time monitoring of the production workshop by transmitting data: All-round monitoring of the production workshop, leaders and production management personnel can easily understand and master the real-time operation of production and equipment in each workshop, find problems in a timely manner, and improve the efficiency of the management staff. All the produced images can be provided to the company's quality inspection department to fully grasp the entire process of product incoming, processing and sales.
Monitoring and transmission of safety public points in the plant area: understand the entry and exit of personnel and vehicles at each entrance and exit to prevent illegal persons from entering the plant area, and use the system's monitoring function to enable management and security personnel to quickly respond to various emergencies and provide accurate on-site information.
Factory transmission alarm linkage function: Using the system's alarm linkage function, when an alarm occurs in the factory area, it can timely understand the scene of the alarm point and provide accurate and timely scene conditions for handling events.
For important locations in the factory area: for example, high-definition cameras are used in front of the entrance and exit to transmit with a Gigabit Poe switch to ensure high-definition recording.
Front-end access layer:
The access layer uses Gigabit 8 + 2 (optical multiplexing) using the latest high-speed Ethernet switching chip, ultra-high backplane bandwidth design, with extremely fast data processing capabilities, improving smooth data transmission performance. It has 8 POE power supply RJ45 ports and 2 upstream Gigabit optical multiplexing ports. Among them, all 8 RJ45 ports support IEEE 802.3af / at standard PoE power supply. The maximum power supply of a single port is 15.4W / 30W, and the maximum power of the whole machine is 120W / 250W. It can automatically detect and identify the power receiving equipment that meets the IEEE 802.3af / at standard, and provides power to the priority mechanism through the network cable, that is, the network cable that transmits data can also transmit power, which not only simplifies the construction process, reduces installation costs, but also For safety. Among them, PoE switches have high performance, simple and convenient use, simple management, convenient networking, low construction cost,
Why recommend POE?
1. Safer: We all know that 220V voltage is very dangerous, and the power supply cable is often damaged, which is very dangerous, especially in thunderstorm weather. Once the power receiving equipment is damaged, then the phenomenon of electricity leakage is impossible. avoid. The use of PoE switches is much safer. First of all, there is no need to pull the power supply, and the 48V safety voltage is provided. The most important thing is that Tianbo PoE switches currently have professional lightning protection design, which greatly improves the reliability of the product.
2. More convenient: Before PoE technology prevailed, it was mostly powered by 220V power sockets. This construction method is relatively rigid, because not every place can pull power or install power, so the position of the best camera is often affected. Obstacles due to various factors necessitated the replacement of locations, which resulted in the emergence of a large number of surveillance blind spots. After the PoE technology is mature, these can be solved. After all, the network cable can also be powered by PoE.
3. More flexible: the traditional wiring method will affect the networking of the monitoring system, resulting in the inability to install monitoring in some places that are not suitable for wiring, and the use of PoE switches to supply power can be independent of time, location and environment. The networking mode will also be much more flexible, and the camera can be installed arbitrarily.
4. More energy-saving: The traditional 220V power supply method requires a large range of wiring. During the transmission process, the loss is quite large, and the greater the distance, the greater the loss. The latest PoE technology uses low-carbon and environmentally friendly skills. Very few, in the long run, can be energy-saving and environmentally friendly.
5. More beautiful: PoE technology makes the grid into one, so there is no need to wire and install sockets everywhere, which makes the monitoring site look more concise and elegant.
