Monitoring device TTA-08 (version R.3)

Overview

The TTA-08 device is an element of a remote monitoring system via an Ethernet network (SNMP v2c/v3) of equipment and objects (data centers, technological equipment, autonomous stations, industrial premises).

It is possible to connect sensors and sensors for monitoring climatic parameters (temperature, humidity), as well as standard security and fire detectors (smoke, motion, glass breakage, window/door opening sensors).
RS-485 and RS-232 interfaces allow you to connect a wide range of additional third-party devices: electricity meter, smart card reader, RFID, industrial systems with Modbus RTU protocol support.
The data from the sensors is processed by TTA-08 and transmitted over the Ethernet network to a client-server SNMP NMS monitoring system or a mobile phone (voice message or SMS).

Connected devices, monitored parameters

• 4 inputs for connecting fire and security alarm loops (with status monitoring and power switching) or “dry contacts”.
• Input for connecting a remote temperature sensor or a humidity and temperature sensor.
• DC voltage measurement input – 5..85V (hardware sensor for UPS control).
• 2 inputs for connecting voltage sensors AC~220V or “dry contacts”.
• 4 digital inputs (Digital Input) for connecting external devices or sensors “dry contacts”.
• 3 digital outputs (Digital Output) for relay control (connection of sound and world signaling).

CAN bus – information exchange highway

The CAN bus is designed to expand the functionality of the TTA-08 device.
Using the CAN bus, it is possible to connect up to 11 expansion modules to the TTA-08 monitoring system controller. This solution allows you to increase the number of monitored loops or control points of the base module within one control domain.

Functionally, the TTA-08 device provides collection, analysis and control of data received from all connected expansion modules.

The CAN bus is a serial bus with two differential signals CAN-H and CAN-L, to which monitoring devices are connected in parallel.
The TTA-08 device and MP expansion modules represent an integral device of the monitoring system with one IP address and a common Web interface.
This solution allows you to monitor up to 140 condition monitoring points.
The advantage of the solution to build an infrastructure monitoring network based on TTA-08 devices with CAN bus support is the ability to place MP expansion modules at a considerable distance from the main controller. In this case, MP expansion modules can be placed in close proximity to the condition monitoring elements.
The maximum length of the CAN bus can reach 250 meters.

Expansion modules

The main task of expansion modules is to increase the number of loops and control points of the base module within one control domain.

The structural diagram of the application of the extension module in the infrastructure monitoring system is presented above.

Unlike the basic module of the TTA-08 remote monitoring and control system for sensors, the expansion modules perform only the functions of collecting and transmitting telemetry.
Having received a value from any sensor, the expansion module transmits the data to its domain controller (the basic module), which in turn performs further processing and management of the received data in accordance with the algorithms of the program logic.
Types of expansion modules available for orderingMP-1.

Brief technical characteristics of MP-1:

• support for up to 12 universal digital inputs (security, fire loops or dry contacts)
• CAN bus
• Ethernet 10/100 Mbit/s

MP-1 can operate in Slave mode (as an expansion module for the TTA-08 device) or in Master mode (as an independent device).

WEB-interface of the device

SNMP Protocol

Support for SNMP v2c/v3 protocol allows integrating the device into a standard network management and control system. The device can generate SNMP trap for all events.

SNMP based management and monitoring system

For simultaneous control of TTA-08 infrastructure monitoring devices, it is possible to use an additional solution from Terratel – the client-server application “TTA Monitor”.

Specialized NMS/EMS TTA Monitor software is a network SNMP system for monitoring digital device parameters that allows monitoring and promptly informing the user about the key operating parameters of TTA-08 digital devices, as well as informing about the occurrence of emergency and abnormal events.

The TTA Monitor software has a client-server architecture and is capable of providing network monitoring of up to 500 digital devices (network elements) of TTA-08.

The application for communication with devices uses either the SNMP protocol or an internal communication protocol. The TTA Monitor program can run under Windows and Linux operating systems.

Monitoring remote objects will allow the dispatcher to quickly make the necessary decisions, remotely switch various systems or give appropriate instructions to personnel.
