In this paper, we study a new smart TTU which uses ARM7 series chip as processor, equipped with ATT7022B based electric meter module and GPRS module for remote data transmission control. Transformer Terminal Unit (TTU is an effective device to monitor the running state of transformers in the distribution automation system. Study on New Smart Transformer Terminal Unit Based on ARM and GPRS Networkįull Text Available Distribution transformer is one of the most important power equipments in distribution network, whose running state exercises a great influence on the stability of the network. Whole test system has characteristics of simple construction, convenience, real time ability and high reliability, which could meet the requirements of actual use. In a remote operation, four-rotor micro air vehicle which fixed airborne data acquisition device was utilized as a middleware between collecting terminal and PC to increase monitoring scope. The results of system could be checked in the form of web pages within a local network which plays a wireless monitoring and warning role. Data information collected was transmitted remotely by wireless transceiver module, and then multi-channel data parameter was processed and displayed through serial communication protocol between the module and PC. ![]() The system with MCU as its core adopted multiple sets of sensor device to monitor environment parameters of different locations, such as temperature, humidity, smoke other harmful gas concentration. Yu, Yanan Wang, Xiaoxun He, Chengcheng Lai, Chenlong Liu, Yuanchaoįor overcoming the problems such as remote operation and dangerous tasks, multi- terminal remote monitoring and warning system based on STC89C52 Micro Control Unit and wireless communication technique was proposed. Multi- terminal remote monitoring and warning system using Micro Air Vehicle for dangerous environment Introduces the work flow of remote intelligent terminal, and the function module of the system are analyzed in detail, and then the terminal of the principle has carried on the preliminary study. And then,it gives a method to realize it. It was designed on SmartARM 2200, uses uC/OS-II operating system and MiniGUI. This paper introduces the function and principle of the remote intelligent terminal. The design of remote intelligent terminal based on ARM The available protocols to develop the communication of RTU are Modbus/ASCII, distributed network protocol (DNP3, controller area network (CAN, International Electro-technical Commission (IEC 60870, transmission control protocol/internet protocol (TCP/IP. The corresponding protocol and communication parameters between the connecting devices will be included in designing a complex SCADA system. The objective of designing the protocols is to check the status of all the input and output field devices and send the report according to that status. ![]() Fundamentally, the architectures of all networks are based on the seven layers of open system interconnection (OSI and International Standard Organization (ISO. Supervisory Control and Data Acquisition (SCADA system is a central station that can communicate with other network using the protocol. (author)Ī Review of Communications Protocol for Intelligent Remote Terminal Unit Developmentĭirectory of Open Access Journals (Sweden)įull Text Available This paper reviewed all the possible interfacing communication protocols for remote terminal unit (RTU. This makes design more reliable and immune to obsolescence. In this paper a new RTU design is described where the complete digital logic of a board is implemented in one single FPGA device using Soft-core processor and EMAC controller with multiple socket support for the Ethernet communication. ![]() These modules can support maximum of four sockets and are already obsolete from the market. Existing RTUs are 89C51 microcontroller based systems where the TCPIP communication is done using Wiznet Module. Distributed Digital Control System (DDCS) architecture is being followed for the plant control and operation, which mandates the need for multiple sockets support in TCPIP Ethernet communication in an embedded system. Remote Terminal Units (RTUs) are single board remote data acquisition and control systems that are widely used in FBRs during all states of plant operation. ![]() International Nuclear Information System (INIS) Design and development of microblaze processor based Remote Terminal Units for Fast Breeder Reactors
