SH- 1( Storm Water Management System) Supplying, installation, testing & Commissioning of ultrasonic sensor in each water storage tank with measuring range upto 5 meters measurement accuracy of 0.5% - 1.0%, Resolution ratio of 3mm or 0.1% (whichever is greater) with LCD digital Display, Analog output of - 4-line system with 4-20mA current, 510 Ù load, 2-line system, 4- 20mA, 250 Ù load with Relay output - 2 group (i.e. AC 250V/8A or DC 30V/5A) with 24VDC supply, Ambient temperature Display instrument - 20~+60°C with IP66 protection etc complete as reqd.

Supplying of Micro Processor Unit having a high-performance 32-bit ARM Cortex-based processor operating up to 72–180 MHz with embedded Flash memory, SRAM, multi-channel 12/16-bit ADC, advanced timers, PWM generation, RTC with battery backup support, watchdog protection, and multiple communication interfaces including UART, SPI, I2C, CAN. The system integrates WiFi SoC supporting IEEE 802.11 b/g/n at 2.4 GHz with built-in TCP/IP stack, WPA/WPA2 encryption, SSL/TLS security, OTA firmware upgrade capability, and dual operating modes (Station/AP). Operating Voltage 9–24V DC input supply with reverse polarity, over-voltage, surge, and short-circuit protection, along with high-efficiency DC-DC regulation for stable 5V and 3.3V rails. Communication is provided through industrial-grade RS485 (Modbus RTU compatible) with configurable baud rate and multi-drop capability. Including heavy-duty electrically isolated relay outputs (NO/NC type) suitable for pump contactor control, along with LED status indication. Including common HMI/Tablet for various setting like pump automation with user-configurable tank level start and stop settings, adjustable hysteresis control, and support for float or sensor-based inputs. The system incorporates automatic pump rotation logic to ensure equal runtime distribution and seamless alternation after each stop cycle. User-configurable priming interval and priming time settings allow efficient air removal and smooth pump startup. Advanced under-current monitoring enables dry-run detection with adjustable threshold settings and automatic pump trip protection. The controller also includes user-defined maximum pump run time protection to prevent overheating or mechanical damage.SCADA compatibility via Modbus RTU/TCP, and remote monitoring capability through WiFi connectivity

➢ Event list, station ➢ System status. Remote Command Execution: Enables users to issue remote commands for controlling pumps, sensors and valves. In order to ensure a high degree of security against undesired operation, a “select-before-execute” command procedure shall be provided. After the “selection” of a hardware, the operator shall be able to recognize the selected device on the screen and all other hardware shall be blocked. As communication between control centre and device to be controlled is established, the operator shall be prompted to confirm the control action and only then final execute command shall be accepted. After command execution the user shall receive a confirmation that the command is executed. In the selected object picture, all attributes like ➢ Authority ➢ Local / remote control ➢ Errors etc. shall be displayed. Event Data Management: Allows users to download and analyse historical event data logs. The Report page shall contain all the commands that are executed for the control and monitoring of the water distribution system.

The event and associated time of its occurrence has to be displayed for each event. The event page shall be automatically updating at real time within maximum of 10sec duration.The operator shall be able to call up the event list on the monitor at any time for the whole water distribution system or sections of it. The events shall be registered in a chronological event list in which the type of event and its time of occurrence are specified. It shall be possible to store all events in the computer for at least one year. The Report page shall be download in pdf and excel format. The Report can be viewed/download in web browser by selection of date and time in From and to format between 1-year period. The chronological event list shall contain: ➢ All Hardware of system like - pumps, sensor, valve. ➢ All Pumps parameter like Voltage, Current, Power Factor, Power consumption etc installed in the system. ➢ All sensor values installed in the system. ➢. All Valve status installed in the system. ➢ Loss of communication. ➢ Filters for selection of a certain type or group of events shall be available. The filters shall be designed to enable viewing of events grouped per: ➢ Date and time. ➢ Hardware ➢ Status
