In the field of industrial Internet of Things, FTU, Lte Modems, TTU and RTU are common communication devices, which have different functions and characteristics.This article will detail the differences between these four devices to help readers better understand their applications in the industrial Internet of Things.
FTU is a kind of intelligent terminal equipment for distribution network automation, which is mainly used in feeder automation system.It has the functions of fault detection, isolation and restoration, and can quickly locate and isolate feeder faults.And the rapid restoration of power supply in the non-fault area is realized through remote control.FTU also has the functions of data acquisition, processing and storage, which can monitor and manage the operation status of the distribution network in real time.
An Lte Modems is a terminal device for data transmission, typically communicating with a remote master, such as a data center or cloud platform.It can convert the format of the data collected by the field device and transmit the data to the remote master station by wireless or wired mode.Lte Modems provides data acquisition, transmission, and control.It is widely used in data acquisition and remote monitoring in smart grid, intelligent transportation, smart city and other fields.
TTU is an intelligent terminal device used to monitor the operation status of transformer.It collects the operation data (such as voltage, current, temperature, etc.) Of the transformer and processes and analyzes them.It can find the abnormal situation of the transformer in time and ensure the safe and stable operation of the transformer.In addition, TTU can communicate with the remote master station to realize the remote monitoring and management of the transformer.
RTU is an intelligent terminal device for remote data acquisition, transmission and control applications.It has the functions of data acquisition, processing, storage and transmission, and can be connected with various sensors and actuators.Realize the remote monitoring and management of field equipment.RTU is widely used in data acquisition and remote monitoring systems in water conservancy, meteorology, environmental protection and other fields.
Application: FTU is mainly used in distribution network automation; Lte Modems is widely used in data acquisition and remote monitoring;TTU is mainly used for transformer monitoring; RTU is suitable for remote data acquisition, transmission and control applications.
Features: FTU has the functions of fault detection, isolation and recovery; Lte Modems realizes data acquisition, transmission and control;TTU monitors the operation status of the transformer; RTU carries out remote data acquisition, transmission and control.
Communication mode: FTU and Lte Modems usually communicate with the remote master station through wireless or wired mode; TTU communicates with the remote master station;RTU realizes remote communication through wireless or wired mode.
Data processing: FTU monitors and manages the operation status of the distribution network in real time; Lte Modems collects, converts and transmits data;TTU collects and processes the operation data of transformer; RTU collects, processes and stores the data of sensors and actuators.
Applicable scenario: FTU is applicable to fault detection and recovery of distribution network;Lte Modems is suitable for various scenarios requiring data acquisition and remote monitoring;TTU is suitable for safety monitoring and remote management of transformer;RTU is suitable for scenarios requiring remote data acquisition and control, such as water conservancy, meteorology, etc.
In view of the above,FTU, Lte Modems, TTU and RTU have obvious differences in application fields, functional characteristics, communication modes, data processing and applicable scenarios.Selecting the appropriate device type according to the actual application requirements is helpful to better realize the functions and objectives of the industrial Internet of Things system.
