Abstract: The rapid growing of the network of railways in India demands the extensive expansion and modernization of the current water supply system to meet the demand of current and future traveler efficiently. With the budget allocated for the modernization of the rail network, it becomes important for the authorities to manage all the resources and get use them sustainably. The increasing population at the railway stations have increased the need for the proper distribution of water. This distribution of water in every sector or zone within the railway station premises needs the control and monitoring for preventing the wastage, misuse & theft practices. The water automation system works on the principle of communication between two similar devices that can function and utilize all the incoming signal of programmable controllers with the computer system of the water network. Different technologies have been studied to distribute/supply the water to each and every sector of the station area. The water flow variations can be monitored by the given flow sensors mounted on the different nodes of the channels. The entire automation units includes Remote Terminal Units - RTU, flow sensors, GSM modules, pH & chlorine demand sensors, specific transducers, and actuators at different nodes of the network and controls the pump stations.
The HMI system is being used to control and monitor the status over a distance and supervise the operations besides controlling the plant activity remotely if needed. The remote action of the operator is governed by the Ethernet through LAN and WAN over a GSM channel. SCADA system for water distribution at the station network enables the operators and station water managers to identify errors and breakdowns in time. The automation system will ease the work load from the already over burned authority in a much efficient manner with providing the additional benefits of energy saving at the source and helps in optimization of the daily water needs at the stations.
