Remote Sensor Monitoring and Control Unit

Access Control and Sensor Monitoring Unit, TTA-08

Access Control and Sensor Monitoring Unit. Device appearance

  • TCP/IP, SNMPv2
  • GSM/GPRS, Ethernet, RS-485, RS-232 Serial Port
  • External Power Supply
  • Up to 20W in Battery Charge Mode
  • Direct Current Voltage from 20V to 70V

This unit is designed to provide remote monitoring (via Ethernet or GSM/GPRS) of the remote equipment and objects (remote exchange capacities, processing equipment, stand-alone stations and industrial premises). It allows to connect detectors and sensors for monitoring climatic parameters (temperature, humidity) as well as standard security equipment (motion sensors, broken glass sensors, window/door sensors, smoke sensors, flood sensors).

Application of the Access Control and Sensor Monitoring Unit

Figure 1. Application of the Access Control and Sensor Monitoring Unit.

Temperature and Humidity Control

Standard configuration of the remote sensor monitoring and control unit allows to connect security equipment (motion sensor, broken glass sensor, window/door sensor, smoke sensor, flood sensor) as well as temperature sensor and humidity sensor.

Use of temperature and humidity sensors allows to build the climatic parameter control system for various premises based on the remote sensor monitoring and control unit.

Use of the dedicated temperature sensor (cascade sensor – CS) allows to build the system for multipoint temperature control/monitoring with the number of control points ranging from a few to several hundred.

The multipoint temperature control system allows to measure temperatures in rooms with specific conditions:

  • server rooms where temperatures of each rack should be measured individually
  • hospitals and laboratory facilities
  • factory floors requiring control of temperature parameters
  • large storage areas

The following products are required to build the Multipoint Temperature Control System:

  • Remote Sensor Monitoring and Control Unit
  • Power/Interface Unit (PIU)
  • Cascade Temperature Sensors – based on customer requirements, from 1 up to several hundred

220V Availability Control and Battery Voltage Control

Remote Monitoring and Control Unit features 2 inputs designed to connect 220V AC voltage availability sensors and one input designed to measure battery voltage.

220V availability sensor is the innovative proprietary product.

Battery voltage is measured within the range from 0V to 90V with +/- 1V accuracy. There is an option of setting the lower and upper battery voltage thresholds using the remote monitoring unit software, which allows to provide alarm reporting (SNMP trap, sound or visual alarm).

Using Remote Monitoring and Control Unit combined with 220V availability sensors and battery voltage control sensor allows to build the power control system in the rooms like a server room.

Figure 4. 220V Availability Control and Battery Voltage Control.

The system is designed to monitor the battery voltage and 220V availability. The system monitors 220V availability (2 inputs) in real time and measures the current battery voltage. When 220V is not available or the battery voltage is beyond the preset lower or upper voltage threshold the system alerts the manager/user by sending visual alarms, sound alarms, SNMP trap or SMS.

RS-232 Serial port to Ethernet Converter

TTA-08 features the functionality of connecting RS-232 and RS-485 serial interface units to Ethernet.

RS-232 and RS-485 Serial communication port external galvanic decoupler interfaces allow to connect a wide range of additional third-party devices to LAN like power supply meters and smart card/RFID readers. The product supports 1 serial port.

Remote Monitoring Unit Web Interface

The sensor data are processed by the controller and sent via Ethernet or GSM/GPRS to the manager/user PC or as a text message to his/her phone.

The Web interface allows the manager to see the current status of all connected sensors of the selected device on his PC in real time.

SNMP

SNMPv2 support allows to integrate the product in the standard network control and monitoring system.

SNMP-Based Control and Monitoring System

To control several monitoring units at a time TTA Monitor application can be used.

The application designed to communicate with devices can use either SNMP or internal communication protocol. TTA Monitor can operate under Windows or Linux operating systems.

Monitoring of remote objects allows the manager to find the required solution and switch systems remotely or instruct personnel as required.

Remote Monitoring and Control of Remote Objects

Remote Monitoring Unit combined with sensors allows to build various systems to monitor and control remote objects:

  • Monitoring system for data processing centers and server rooms
  • Monitoring system for industrial premises
  • Monitoring system for storage areas
  • Monitoring system for pharmacy premises
  • Monitoring system for food production and refrigeration facilities
  • 19″ rack monitoring over GSM and LAN
