The Q26_RTU GSM/GPRS/EDGE Remote Monitoring& Remote Control System is a complete Remote Telemetry unit. It contains a GSM/GPRS/EDGE Modem and
control circuitry. It is capable of controlling up to 2 Relay outputs and monitor 2 Digital inputs and 2 Analogue inputs.(Analogue input support: Detect Water leaks,
Monitoring Temperatures for out-of-range conditions, Monitor Humidity for Damaging High Humidity Levels and monitor fuel levels).

The Q26_RTU GSM/GPRS/EDGE Remote Monitor &Remote Control System is operated by the sending of SMS and GPRS/EDGE. The GSM/GPRS/EDGE controller
can be used as a remote telemetry system; users can directly control the output relays from a simple text message or GPRS. The controller can also be used as a
remote monitoring system; the unit can automatically notify the user whenever the any inputs change state and inputs counter.
The Q26_RTU is complete with extend function include DI/DO/AI by UART2, support back up battery and built-in Quad-Band Modem -900/1800/850/1900.

Characteristic

 

Q26_RTU is a versatile SMS alert device suited for most monitoring needs. It is
simple to use yet is packed with powerful functionalities to meet a wide ranging
industrial and commercial and residential applications
Standalone Operation
It is very easy to setup, install and use. User can set parameter by Remote or
Local mode. We can provide local configure tool and Remote configure command for SMS

 

2 Digital Inputs

Most equipment today does provide some form of alerting signal to interface tomonitoring devices from reporting of various

malfunction or abnormalities. Thereare various kinds of signal that the equipment can send out, most common of which are

opening or closures of one or more switch relay contact.UPS usually provide signals such as incoming power fail, battery mode,

battery level low, and switchoverfailure. An air conditioner system may provide signals such as system on/off,compressor over

temperature, low gas pressures, etc.

 

Equipments to be monitored are connected to Q26_RTU using these alarm signaling contacts. Q26_RTU keeps a constant watch

over all the contacts. Whenever any contact input changes status (either from a close to open or from an open state to close state)

it is captured by Q26_RTU. It will then process the input according to the configuration provided by the user before. The correct SMS

messages will be sent to 5 mobile phone users.

 

Q26_RTU is so fast in capturing the change of status of any signaling contacts that no event will be missed out up to 2 inputs can be

monitored directly. The flexibility of Q26_RTU is in allowing remote query of input status and input counter using SMS.

 

To change contacting mobile phone number is also very easy. Authorize personal remotely using SMS command to add, change or

delete mobile phone  number in Q26_RTU.

 

2 Analogue Inputs

The Q26_RTU has 2 analogue inputs that can be configured to measure a 4-20mA or 1-5VDC signal. It will generate reports

when the monitored signal reached to programmable set points.

Two programmable set points can be programmed for each analogue input.When the monitored signal crosses a set point a specified

action will be performed like switching the output relay or sending an SMS report.

 

2 Digital Outputs

Q26_RTU is a 2 way device. Besides monitoring inputs and act upon such inputs it also allow mobile phone users to compose SMS

messages to it. When Q26_RTU receives any SMS, it will looks its memory bank to see what it is supposed to do and action according .

No action SMS are ignored.

 

Up to 2 relays can turned on and off by messages received from mobile phone. Querying Inputs and Outputs Status and Analogue Value

 

Authorized groups can also query the status of all input or output. This is very useful feature to determine the present status and value of

all inputs or outputs. The enquirer need not wait for an alarm to happen in order to receive the given I/O  status.

 

Turning On/Off Device Remotely

Authorized users can send a SMS command to trigger on or off the digital output.Upon receiving the command, Q26_RTU will perform the

instructed action. After the on or off action is done, it will send a reply to the querying mobile phone as an acknowledgement.
There are 2 digital outputs that can be independently or meanwhile controlled.

 

Remote Editing of Mobile Phone Numbers

Q26_RTU has a feature to allow user to remotely add, change or delete any mobile phone numbers in Q26_RTU memory.

 

Re-assigning of operation personnel, a change of mobile phone number is also common. Rather than having to physically go to the installation

site with notebook computer, the authorized personnel can perform the change from anywhere using mobile phone. Where there are many

installed sites, this feature saves time and afford

 

For safe, Q26_RTU have a supper mobile phone number set. It can change all parameter and query all parameter. Authorized user can to query

the parameter and  receive the alarm.

 

Device ID

Supper mobile phone group can perform and change Device ID by sending a command to Q26_RTU

 

Reset Device And Adjust System Clock

Supper mobile phone group can reset Device and adjust system clock by sending SMS

 

GSM Modem

Integral to the design of Q26_RTU is a GSM/GPRS/EDGE 900/1800/850/1900 industrial grade modem. Its capabilities and

performance are highly optimized by the operating firmware.

Any change in the GSM signal and receiving conditions are detected quickly and the software automatically takes care of signal errors.

 

Reliable Performance

Besides running the necessary program to perform all the required functions,Q26_RTU has diagnostic routines running alongside.

Being a monitoring device,Q26_RTU must have a very high operating reliability and stability. Every section of Q26_RTU is monitoring each other.

Should the modem fail to perform its required role, the controller will interrogate and restart the modem.

 

GPS Location Information

Q26_RTU provide GPS location information .User can get GPS location information by sending a SMS.
And the user can open the response in the smart phone with Google map and show your location.
