プロジェクト紹介


Project Introduction
A growing population produces more wastewater that needs to be collected and processed by water treatment plants before being released back into the environment. In water treatment systems that need to accommodate changes in elevation, sewage lift stations are used to pump wastewater from low-lying areas to higher ground. In the past, lift stations often lacked monitoring and alarm systems, which made it difficult for administrators to respond in time to system failures. Due to the critical role these establishments play in the wastewater treatment process, many lift stations in Texas have adopted Moxa's ioLogik E2210 series devices as their RTUs in setting up lift station alarm systems.

 

System Requirements
Since sewage lift stations collect wastewater from households and factories, the status of the station must be monitored for potential failures or overflow to prevent environmental contamination. Establishing an alarm system in lift stations requires monitoring the pumps' on/off status, floats, flow meters, rainfall intensity, and security systems around the lift stations. Wireless communication is required for stations located in remote areas where landline communication is not available.

 

System Description
The lift stations in Texas utilize the ioLogik E2210, an RTU unit with 8 digital inputs and 12 digital outputs, along with a GPRS IP router. First, the ioLogik E2210 is set to collect status reports for the lift station's pumps, power supply, and float. The GPRS IP router then reports all anomalies to a voicemail service that makes outbound calls to engineers for different alarm situations. In addition, the ioLogik E2210 actively sends the tracking records to the central SCADA system with its patent pending Active OPC Server tag update function. The ioLogik E2210 is also used to connect rain gauges and flow meters. By using the ioLogik's counter mechanism, engineers can track the rainfall intensity and wastewater flow speed for any potential flood alarms. To provide onsite security for lift stations, which are often remote and widespread, the ioLogik E2210s are connected to fire detectors and magnetic switches for intrusion alarms. All alarm signals are updated to the central SCADA so field engineers can receive email and voicemail notifications.
