As the population continues to rise, people begin to build water supply pumping stations, pumping underground water from underground water wells, sterilizing them and obtaining clean water. The pumping station is a complex interlocking system consisting of a number of different distributed equipment including sterilization equipment, surface storage tanks, overhead storage tanks, well pumps and propulsion pumps, etc. Project Profile As the population expands, Feedwater pumping stations are generally built to meet the need to maintain a clean source of water from decontaminated water in underground wells. The feedwater pumping station is a complex internal blockade system consisting of many different distribution equipment including sterilizing equipment, surface storage tanks, overhead storage tanks, well pumps and propulsion pumps. The use of data acquisition and control systems, multi-level feed pump and sterilization process management. System Requirements Remote Wireless Data Acquisition to SCADA Real-Time Data Acquisition Local Control Logic for Reading Analog Inputs and Triggering Digital Outputs Moxa's Solution Moxa used two sets of ilLogickE2242s for this application. IoLogikE2242 is a 4-channel analog input and 12-channel digital input / output RTU, to provide accurate connection options for the pumping station. A group E2242 is used to control the pump to pump water from the ground to the surface tank. An analog channel monitors tank level and a digital port for pump control. The E2242 is easily configured using simple Click & GoTM technology, turning on the pump when the analogue channel reports a low ground water tank level, and shutting down the pump to prevent water spillage when the tank is full. At the same time additional use of digital input, monitoring pump status and power status. The second E2242 is used on the other side of the system and controls the pusher pump to pump water from the surface storage tank to the overhead storage tank. These E2242s operate in a similar manner and control the pusher pump to operate based on the current water level of the overhead storage tank. At the same time, an additional analogue channel was used to monitor the flow meter used to measure the total flow of the pipe connecting the ground storage tank to the overhead storage tank. Feedwater pumping stations are usually located where water wells may be found, which is extremely inconvenient. Remote pumping stations are usually not connected on land at the site and must use GPRS communication for data transmission. However, due to the limited bandwidth of the GPRS network, a constant acquisition and response test acquisition architecture between the host and the client is not feasible. Use Moxa's highly-efficient OPCServer software with the wireless IP router E2242 to intelligently and efficiently "push" pump and power status alarms to a central SCADA system without incurring expensive GPRS traffic
