Industrial Ethernet switches, which are used in industrial control field, are open and widely used due to the adopted network standards. They can adapt to low temperature and high temperature, resist electromagnetic interference, prevent salt spray and have strong earthquake resistance. Industrial Ethernet switches use a transparent and unified TCP/IP protocol, and Ethernet has become the primary communication standard in industrial control.
Industrial wireless access point is a wireless switch used for industrial field wireless networking. At present, the main technology is 802.11 series, and the whole protocol is 802.11, 802.11a\b\g\n and so on. Industrial wireless access node (session point or access bridge): is a very wide name, which includes not only a simple wireless access point (wireless AP), but also a wireless router (including wireless gateway, wireless bridge) A general term for such devices.
Industrial IoT gateway integrates functions such as communication management, data reception, protocol conversion, data processing and forwarding, and supports mobile phone WiFi on-site debugging, also called wireless gateway, industrial IoT intelligent gateway, industrial communication gateway, wireless sensor management host, etc. Sensor network products. XL90 Industrial IoT Intelligent Gateway can receive multiple wireless sensor data at the same time, support 2 Ethernet ports (Ethernet), RS485 and 1 RS232 serial port, wireless transmission and other uplink modes, optional GPRS, 433MHZ, 2.4GHZ, WI- Wireless transmission methods such as FI.
The serial port networking server is also called serial port server. The two keywords are serial port and network. The network is divided into two types: internal network and external network. The internal network generally refers to Ethernet, and the external network refers to the Internet. It is an effective means for communication on a global scale. Before the network is popular, data exchange is usually carried out between the device and the computer through simple RS232; if long distance transmission is required, RS485 can also be used (normal RS485 can transmit 1200 meters, industrial grade can transmit 5000 meters).
Cloud computing is the development of Parallel Computing, Distributed Computing, and Grid Computing, or the commercial implementation of these computational science concepts. Cloud computing is Virtualization, Utility Computing, infrastructure as a service IaaS (Infrastructure as a Service), platform as a service PaaS (Platform as a Service) and software as a service SaaS (Software as a Concepts such as Service) are mixed and evolved and jumped.
