IIoT called industrial things , at higher speeds and get access to larger amounts of data, break the data silos, and all personnel, and processes the data connection from the plant floor to the executive offices. Business leaders can use IIoT data to fully and accurately understand the mode of operation of enterprises, to help them make better decisions. Compared civil IOT, mainly high reliability reliable connection, complex work environment, low latency requirements http://www.elecfans.com/d/706171.html
MQTT) transmission protocol is fast becoming the standard IIoT because it has a lightweight overhead, publish / subscribe model, as well as security protocol bi-directional capabilities.
Chip: + AD + MCU wireless integrated chip.
Connection scheme: M12 has become the industrial Ethernet , analog interface and serial digital interface of choice for interconnect solutions.
Pocket IO IO platform and take advantage of its rich program features not only provide a direct replacement solutions, also offers reference designs for custom requirements
Sensor connection interfaces: O-Link (MAX14827A other special IO-Link Transceiver / MAX14819 the master IO-Link ), HART, or WirelessHART
Industrial Ethernet protocol has PROFINET, EtherNet / IP (the most widely used), EtherCAT and POWERLINK
Wireless: WLAN is currently the most popular wireless technology, followed by Bluetooth
LTE Cat-M1 and NB-IoT like narrow band cellular service adapted to the case without an Internet connection or a poor connection, protocol and Pycom G01 NimbeLink NL-SW-LTE-SVZM20 (AT commands), and other cellular transceiver module according to the narrowband LTE protocol
