Work Detail

Providing Of Microcontroller Based Wireless Controller System For Water Level Management And Other Accessories Etc. For The Existing Water Supply System At Transport Authority, 5/9 Under Hill Road, Delhi.- 1 Supply, installation, testing, and commissioning of a microcontroller based wireless controller system designed for managing water levels and pressure across multiple remotely situated tanks. The wireless controller communicates on 865~868Mhz band for long range communication. This control system integrates microcontroller technology with wireless data reception capabilities to receive various sensor data wirelessly to indicate & control water automation system. It will indicate water level in Percentage with One percent resolution alongwith tank ID through 4-digit LED/LCD display (minimum 56mm height) for real-time visualization of water levels and sensor data, alongside four potential-free relays that enable the system to operate single or dual motors (three-phase) based on specific conditions. The controller starts the motors when water levels in any linked tank drop below predetermined thresholds and stopping them when all tanks reach capacity. It also responds to data from pressure transmitters, ensuring motors operate within defined pressure ranges in pipeline. It must have a built-in RTC with timer functions, enabling automated motor control based on configurable schedules, while providing comprehensive runtime statistics for monitoring purposes. There should be an audio & visual alarm, if water level in any tank cross threshold limit for overflow level. It should also give visual indication for various fault conditions. Operating voltage single phase 180~260Vac. It can also indicate status of motorized valve and minimum number of opened valves can be set beyond which it will stop the motor to avoid excessive pressure in pipeline. It will also indicate rising/ falling trend of water level in overhead/ underground. 2 Supply, Installation, Testing & Commissioning of Battery operated (to power minimum 8Year) RF based ultra low powered wireless water level data top transmitter (minimum 15dBm power) operating in frequency band 865~868mHZ, confirming to EN 300 220 and ingress protection IP68, with scale and corrosion free capacitance based level sensor to measure water level percentage from 0% to 100% (± 5% with 1% resolution for tanks upto 10mtr depth with auto calibration sensor. It should also calculate trend & rate of rise/ fall of water level and transmit the data alongwith water level data. It will have input for detection of conductivity based flow in pipeline and on/off status of motorized valve and send the data wirelessly. It should have a technique to avoid collision of RF signal and minimize corruption of data. It should have CRC check in transmitted data to detect error in block of data. (Underground sump) 3 Supply, Installation, Testing & Commissioning of Battery operated (to power minimum 8Year) RF based ultra low powered wireless water level data sump transmitter (minimum 15dBm power) operating in frequency band 865~868mHZ, confirming to EN 300 220 and ingress protection IP68, with scale and corrosion free capacitance based level sensor to measure water level percentage from 0% to 100% (± 5% with 1% resolution for tanks upto 10mtr depth with auto calibration sensor. It should also calculate trend & rate of rise/ fall of water level and transmit the data alongwith water level data. It will have input for detection of conductivity based flow in pipeline and on/off status of motorized valve and send the data wirelessly. It should have a technique to avoid collision of RF signal and minimize corruption of data. It should have CRC check in transmitted data to detect error in block of data.(overhead tank) 4 Supply, Installation, Testing & Commissioning of 230Vac/ 5V DC operated RF signal booster operating in Frequency band 865~868mHZ confirming to EN.300.220 to relay/ transmit the RF signal received from multiple transmitters to further distance with LED based instant indicator. It should have a technique to avoid collision of RF signal and minimize corruption of data. A mechanism should be there to avoid circular transmission of data between repeaters. LED based visual indication should be there to indicate signal strength of received wireless data. It should have RF receiving sensitivity of minimum -125dBm and transmission power of minimum 15dBm. It should be configurable to filter out RF signal of particular transmitters to reduce the transmission signals in Air. It should have shock proof ABS body with IP65 rating and must have suitable mounting arrangements on wall or stand. 5 Supply, Installation, Testing & Commissioning of 12V DC operated wireless RTU to receive data wirelessly from remote sensor data transmitters/ RF boosters and push the data to BMS/ controller unit through UART and to the server through 4G/ 5G GSM network. This device will be equipped IOT sim of cellular network service providers. It should have LCD/ OLED screen to display various parameters and status of network/ connectivity. The enclosure should be IP65 rating with suitable mounting arrangements. It should be equipped with wifi module to connect with server through available wifi network. Various settings should be configurable through common web browser using wifi feature. 6 Providing web based remote Controller/ Water level monitoring system by providing access to control/ information panel at Central server of minimum Tier-III level data centre in India. It will trigger SMS alerts for various events on crossing limits. The cost include only for access to server/ application and it does not include the cost of required hardware. The cost of hardware will be charged separately but the cost of running the services is included .For access to Motor controller/ Valve Controller to operate - For 12 months 7 Supplying & Laying of one number PVC insulated and PVC sheathed / XLPE power cable of 1.1 KV grade of following size direct in ground including excavation, sand cushioning, protective covering and refilling the trench etc as required. 8 4 x 16 sq.mm 9 Supplying & Laying and fixing of one number PVC insulated and PVC sheathed / XLPE power aluminum conductor armoured cable of 1.1 KV grade of following size on surface as required. 10 3.5 x 25 sq.mm
