Overview:
Substation Management Terminal is specifically designed for system applications substation remote terminal. A variety of different models of multi-function watt-hour meter. Terminal Performance strict compliance with the relevant international standards,national standards and industry standards, performance,security and stability,high accuracy,storage capacity, meter reading quantity,good compatibility,easy to expand and facilitate the substation,power plant installation and maintenance in the distance telecommunications mainly uses Ethernet and GPRS / CDMA mode public network.
Main functions:
Data Acquisition: Support DL/T645-1997 "multi-function watt-hour meter communication protocol", is compatible with other known statute. It can collect the various data of Multiple functions Meter from different manufacturers;support Customize options information collection and transfer functions;can be collected by hand, timing automatic acquisition, ting acquisition tasks;
LCD: the terminal has a backlit LCD display, can display meter reading information, communication information, fault information, alarm information and other content; support recycling display and keypad display, display content can be set;Have indicated that GPRS / CDMA signal strength of the instructions to ensure that In the context of its provisions, to carry out normal communication;
Self-diagnosis, self-healing functions: device has internal components automatically patrol check functions: software and hardware fault condition automatic restoration; Device with lights that can reflect the installation on-site operational status (normal work, communication with the meter) and can automatically record device operational status;
Data Storage: With strong ability to pre-calculation and statistics, data can be stored more than 60 days (collected 40 tables, acquisition cycle for 15 minutes); , the stored data can be stored more than 5 years when the power outage;
Remote settings, upgrade: support remote settings, parameter modification and remote Terminal application upgrades; device reset and parameter modification do not affect the data integrity.
Main features:
With GPRS communication interface, real-time high, transmit large volumes of data, not struck by lightning; also has Ethernet, a public wireless network interface
Automatic data collection by the collection program Issued through the main station and according to set time intervals to save.
Able to adapt to high and low temperature and high humidity or other harsh environment
With the terminal remote reset function
Through the remote on-line application functionality upgrades
Communication protocol, to support a variety of IEC60870.5-102 communication protocol with the master station
With the data forwarding, forwarding the vicinity of other smart devices (such as multi-function watt-hour meter) data
With the maintenance of communication ports, through the interface to modify the device parameters at local.
Have equipment self-test function, be able to report operating status and fault information
Backlight function dot matrix LCD widescreen
