solar inverter. This way a GSM/GPRS RMS, Remote Monitoring System works.
A GPRS enabled gateway is used for transmission and reception of data between
GSM/GPRS RMS, Remote Monitoring Systems for Solar Water Pumps and solar
inverters. This GPRS gateway receves data from the field solar pump controller
through Wireless Modbus RTU. Data is processed inside the microprocessor and
sent to air in small data packets through GPRS technology. This data is travels
to target server computer via assigned staic IP address over the internet. Once
detected the static IP receives the data packet and sends it to the respective
port for further processing and storage. Once the data is decoded and stored in
tabular form its ready for live monitoring and report generation.
Govt agencies are giving subsidy to farmers for installing solar water pumps. So
the farmers can contact concerned authorities for getting the subsidy and
installing the solar water pump in their fields. These solar water pumps are
being continuously monitored by a nodel agency for the perfect operation os
solar water pumps. These pumps have controllers fitted with a
GSM/GPRS RMS, Remote Monitoring System. This GSM/GPRS RMS, Remote Monitoring
System is connected with a centarl server so that regular data is received from
the solar water pump and solar controller from the field. This way a record is
being maintained for how much water in pumped out, how long the solar water pump
was operaional and how long it did not work.
Many corporate house are providing subsidy under CSR for installing solar
inverters fitted with GSM/GPRS enabled Remote Monitoring Systems and RTUs. This
GSM/GPRS RTU provide field data of installed solar inverter for checking and
analysis. The company comes to know the actual working hours of the solar
inverter, how much electrical energy it has generated, how much foot prints are
saved to control the ait polution. This way WIreless Modbus RTUs are playing a
major role in the industry for data collections of filed instruments such as
solar water pumps, solar inverters. We should aso install solar inverters in our
homes to harness solar energy and save on electricity bills.
We can connect a GSM/GPRS enabled Wireless MODBUS RTU/RMS with industrial water flow
meter. Water volume flowing through the flow meter can be recorded in the
central controlroom. This helps in reviewing the flow rate of water, total water
dispensed through water flow meter. One can generate daiy reports, glow charts
etc.,. with the data stored on the central server. This is possible using
Softbitonline GSM/GPRS enabled wireless Modbus RTU. A special web based
interface is designed for Birla Cement Plane for complete water management.
GSM/GPRS enabled Wireless MODBUS RTUs are installed al different locations for
measurement of water flow and total water consumbtion in that particular zone.
Data of all the water flow meters is being sent at Softbit Central Server
installed at New Delhi, India. Live monitoring is done by Birla Engineers within
the plant and daily reporta are generated for review,analysis and taking
necessary remedial action whereever necessary. The field water flow meter is
connected with the
GSM/GPRS enabled Wireless MODBUS RTU/RMS through hard wires to send data through
Modbus protocols. The location co ordinates are sent through GPRS SIM Card.
These co ordinates are decoded at the server and and final location of the water
flow meter can be checked. So you can check the location of all the installed
water flow meter through GSM/GPRS enabled Wireless MODBUS RTU/RMS.
GSM/GPRS enabled Wireless MODBUS RTU can also be used as Remote Monitoring
System or RMS for Solar Applications such as remote monitoring of solar water
pumps, remote monitoring of solar inverters, remote monitoring of solar street
lights, remote monitoring of solar power plants etc.,. In case of remote
monitoring of solar water pumps the RMS is connected with the solar VFD to
capture data through MODBUS communication via RS485 port. The captured data such
as frequency, ac voltage, load current, power, kWH generated etc.,. is
transmitted to Softbitonline remote central sevre installed at New Delhi, India.
This data is then decoded and used for live monitoring of solar water pumps,
solar inverters, solar street lights. Data is also used for daily, weekly report
generation. This way we can use Wireless MODBUS RTU as GSM/GPRS enabled Remote
Monitoring System or RMS for solar water pumps, solar inverters and solar street
lights. Users are given options to select date of report start and date upto
which report is required. A calander is provided for start and end date
selection. Once selected the report for selected time period is displaced on a
web page showing all the set parameters of the filed instrument. This report
then can be exported to an excel sheet for sending the same to concerned
departments for review and analysis. Softbit manufactured GSM/GPRS Wireless
Remote Monitoring Systems or RMS for solar water pumps and solar inverters has
many built in features. Features like storage of data on SD card. SD card
may be 8MB or 16MB or 32MB, LCD display for local data monitoring on site, timer

feature), analog input for connecting a desired sensor with 0 - 5 V output or 4
-20 mA output, digital input for connecting a sensor with pulse output,
digital output in shape of a micro relay for controlling the connected
device/field instruments. So Wireless GSM/GPRS enabled MODBUS RTU has many
inbuilt fetaures to suit your requirements.
We provide SCADA application for sending control commands from control room to
remote RTU in the field. By pressing a switch in the SCADA applcation the remote
unit can change the state of a connected device like electric motor or lamp from
on to off or off to on. Similarly, analog signals (optional) can also be
sent to the remote unit to control the speed of otor or intensity of light or
flow of water through a water flow meter. This way the GSM/GPRS enabled RTU/RMS
can be used for controlling the devices connected with the field devices.
SCADA application works on TCP/IP protocols. It receives signals or data strings
or command strings on through a static IP on a specified port number. This staic
IP and server port number are embedded in the RTU/ RMS during the process of
configuration and loading of code/program. All Softbit GSM/GPRS enabled
RTUs/RMSs are configured for TCP/IP protocol to communicate with the SCADA
application. Each GSM/GPRS enabled MODBUS RTU is assigned a unique ID at
the time of manufacturing and programming in the factory. So the data strings
received at server end are seperated on the basis of unique IDs and
corresponding data is strored for each RTU with its respective unique ID. Data
is stored in MS Access tables This data is then used for live monitoring and
report generation.
This data is
then pulled by a web based SCADA for remote monitoring of the distant machine
and plant. We can monitor all the electrical parameters of the machine for its
performance and thus to check the productivity of the plant. Any abnoramal
value can be detected and compared with the saved value to find the deviation
and problem in the remote system. This helps in provoding in
stant service at
remote site by sending a technician with required material.
Control room supervisor can also check the remote RTU is healthy or not. And if
found defective he can depute someone to replace the field RTU. All this is possible
with the help of GSM/GPRS enabled RTU/RS or Wireless MODBUS RTU.
A GSM/GPRS
Wireless RTU/RMS is an electronic circuit having a microcontroller, capacitors,
resistances, ICs and a PCB to mount all thes components. The power supply for
this may be assembled on the PCB itself or external type depending upon the
application. The microcontroller of the device is the heart of the GSM/GPRS
Wireless RTU/RMS. A pre writted code in C language is downloaded in the
microcontroller which gives instructions to input and output ports of the
controller to perform specifc functions. These ports in turn send commands to
the peripheral devices such as relays, LEDs, temperature sensors, humididity
sensors or any other sensor to send and receive dats. The program of the
controller can be updated externally, if required. This updated code is then
downloaded in the micro-controller using a cable and physically connecting the
controller through a USB cable. On air downloading can also be done in advanced
controllers is designed so.
