GSM 3G M2M RTU
Automation solution
1. Brief Introduction
The GSM 3G M2M RTU inbuilts
ARM® Cortex™ 32 Bit RISC Core, 168 MHz inside, RTOS system. It is a multi
I/O port remote terminal unit, through the RS232/485 port can extend up to 64 additional I/O or connect
intelligent meters or PLC. It is special for BTS monitoring, remote data acquisition, telemetry, BTS monitoring,
access control, ATM, generator monitoring, Pump station monitoring, weather satiation monitoring and other
applications. It supports voice communication, SMS, GPRS, 3G and RJ45 LAN IP communications.
The GSM 3G M2M RTU can be used as remote access control. The authorized users can open the gate or turn
on the machine with a free charge call at specified time.
The GSM 3G M2M RTU supports Modbus RTU, Modbus TCP, TCP/UDP protocol, transparent data
transmission over GPRS/3G, RS232, RS485, RJ45, performs as Modbus Master or Modbus Slave. It can
integrate into present SCADA or DCS or HMI directly.
The GSM 3G M2M RTU can be used as Modbus RTU SMS Alert Alarm, when the data acquisition from
RS232/485 exceeds threshold value, it also can send pre-definition SMS to users.
The GSM 3G M2M RTU can be used as:
A Switch with SMS Remote Control
. SMS texts for switching particular terminals on/off are
configurable.
A Modbus RTU SMS Alarm
. It can be used as Modbus RTU SMS Alarm, when the data/value
acquisition from RS232/485 exceed the threshold, it can send SMS to alert the users immediately.
A Timer-Switch which can be activated automatically
. It can be used as preset time when the GSM
3G M2M RTU
need work and when it needn‘t work.
An Access Control unit.
Up to 10 tel. numbers can be authorized for dial to access control and open
the electricity door directly with free charge.
An automation system.
Each input can link to output actions, this is very useful when the temperature
upto appointed value, need switch on the air-conditioning immediately, or when water overflow and need
switch on the dryer, or when somebody broken into the door or windows need to start the CCTV and
Siren.
A SMS reporter.
The GSM 3G M2M RTU can setup daily automatically report its current status to users.
A SMS Alarm Controller.
The IO activations or deactivations can be reported by SMS and optionally
confirmed by phone calls. Each input can have its own message texts and the message can be
programmed by users.
A Pulse Counter.
The digital inputs can be used as the pulse counter, the user can setup both of interval
value activated alarm and total value activated alarm.
A Data Logger.
The unit can save the all of the acquisition data in internal memory storage and upload
to internet by GPRS /3G/RJ45/RS232/RS485 network according to schedue, no distance limitation.
A Wireless Data Acquisition to SCADA or HMI or Monitoring Center.
The unit can acquisition the
varity data(E.g.: Pressure, Level, Current, Voltage, digital input status, pulse counter, digital relay output
status, temperature value, humidity value and other) and upload to the SCADA(Real time dynamic data)
or HMI or Monitoring Center by SMS/GPRS/3G/RJ45/RS232/RS485, no distance limitation.
A Wireless Intelligent Meter Reader.
The GSM 3G M2M RTU can be used to read remotely intelligent
meter data to SCADA or monitoring center by RS232 port or RS485 Port.
