In modern network design, the use of Ethernet switches can significantly improve the application performance of the entire user network, that is, all devices connected to the network can communicate with each other through the Internet, from computers, PDAs, communication devices to instruments and household appliances.
Ethernet (Ethernet) is a computer LAN technology. The IEEE 802.3 standard developed by IEEE gives the technical standard of Ethernet. Ethernet has the advantages of wide application, low price, high communication rate, rich software and hardware products, and mature application support technology. At present, it has been widely used in the resource management layer and executive manufacturing layer of integrated automation systems in industrial enterprises. In fact, applying Ethernet products to high-standard industrial environments has become a new development trend. In order to achieve the required reliability in industrial applications, users' industrial Ethernet switches must have the following characteristics:
â— Redundant power input to prevent single power failure
â— Ring topology, providing redundant paths
â— Built-in high-quality and high-reliability parts to ensure a long mean time between failures
â— Can be applied to super-standard temperature conditions, such as -40 â„ƒ ~ 75 â„ƒ
â— Sturdy and durable shell, keep it away from harmful substances
â— Comply with industrial regulations (CE, FCC, UL, etc.), and pass strict tests such as impact, drop and shock
Industrial Ethernet switch products can use enterprise information networks to publish and display real-time plant operating data within the enterprise. Managers can perform real-time real-time remote monitoring, remote device debugging, and remote device fault diagnosis on site operating conditions through a Web browser. deal with. The easiest way to achieve this is to use an independent Ethernet controller to connect a control host with a TCP / IP interface and a field device with an RS232 or RS485 interface. The Ethernet switch here acts as a bridge between the general computer network and various types of equipment on site.
Classification of Led Display Module
From the light color
LED display module is divided by color:
I. monochromatic modules, such as single red, single green, single blue, single yellow and single white modules
2. Two color modules, such as red and green, red and blue.
3. full color module is mainly a product with red, green and blue primary colors on one LED module
According to the purpose of LED display
LED display module is divided into indoor, semi outdoor and outdoor, grid screen, strip screen, glass screen, etc. according to the different use space.
From the use of lamp beads
According to different LED packaging devices, LED display module can be divided into: LED display module of direct light, LED display module of indoor lattice, LED display module of surface mount.
Divide by pixel spacing
According to the LED pixel spacing, generally used more is: p1.25, p1.875, p1.56, P2, P3, P4, P5 and so on.
LED display function
1. Play the role of commodity publicity and attracting customers.
2. Play the role of store decoration and improve the level of enterprises.
3. Play the role of lighting and innovation.
4. Play the role of popularizing knowledge. (it can be used to play small information of enterprise products and knowledge of relevant industries)
5. Play the role of bulletin board. (promotion, recruitment information release)
6. Act as a foil to the atmosphere. Through the display screen, you can play the welcome words of superior leaders and various VIPs to visit and guide, and the celebration words of various major festivals.
7. It plays a warning role and is often used for road traffic LED navigation indication, etc.
It is undeniable that the ultimate purpose of establishing billboards is to publicize commodity information, attract target customers and make the most profit as much as possible. Led billboard is to achieve this goal to become the first choice of enterprise publicity.
