EIS is a comprehensive Environmental Information System to solve your environmental monitoring needs. Some EIS2008 features are:
The system provides a network to gather data on environmental parameters relating to air quality, water quality and water resources. The acquired information is processed and presented to the user at a central site, in the form of real-time data reports and/or using alarm annunciation. EIS is distinguished by the utilization of colour graphic displays, such as site maps, with real-time data displayed at the appropriate location. The central system produces historical reports in the format required by regulating agencies, from a database updated automatically from the individual data bases at remote sites or other EIS systems.
A typical system consists of a number of remote site locations, where data is acquired, and a central site where the data is presented. At the remote sites, data loggers, such as SCADAPack RTUs (manufactured by Control Microsystems Inc), acquire data from a number of sensors or instruments. The SCADAPack AQDL3 RTUs utilize a 'C' program, designated AQDL3, to process, validate and average the data for storage and on-site reporting and for transmission to the central on request. do the same.
All parameters are processed in a manner appropriate to their characteristics. For example, pH is averaged logarithmically, wind utilizes vector-averaging,
and precipitation is totalized. Auto calibration scheduling and processing with invalidation and result reporting, an important
feature for quality control of air quality data, is performed by the AQDL programs as well.
Communication between central and remote sites can be via dial-up or leased lines, by using a radio link or a TCP/IP connection. It always uses an industry standard error-free protocol ("MODBUS RTU") to ensure reliable data transfer over noisy remote communication links. EIS can support data loggers other than TeleSAFE or SCADAPack RTUs; please contact us for details.
Supported sensor types include air quality parameters (SO2, NO, NO2, O3, H2S, PM10), water quality parameters (pH, turbidity, conductivity, flow) and meteorological parameters (temperature, wind direction and speed, precipitation, humidity, solar radiation, barometric pressure).
The central system hardware consists of a Windows computer. EIS2008 can be networked over a LAN or WAN.
