SADEC – Data Acquisition System for Continuous Emissions
SADEC – Data Acquisition System for Continuous Emissions Data acquisition software for data acquisition and processing of continuous gas analysers (CO, NO, NO2, SO2, O2, particles, etc.) which supports the four most common communication standards presently in use: analogue signals 4…20 mA, Modbus RTU, OPC and CSV files. The application is highly configurable with a simple and clear interface. All the data is collected in real time in an SQL database, returning the answer to all types of queries intuitively. The data is shown in tabular and graphical formats and can be exported as a PDF or Microsoft Excel file. Following the protocol of the Ministry of the Environment, just by entering the necessary data, the program will automatically create the relevant files and send them (e.g. via FTP servers) to the receiving system. The process is entirely automatic. Typical Applications • Current Legislation • According to the Network of Atmospheric Emissions of each region, and depending on the pollutant, the program controls and sends the required data to the corresponding Ministry of the Environment • Intelligent control of the files sent to the Ministry. If the connection is lost, the system continues to process the information and forwards it when the connection is restored • Manual parameterisation of the percentages of acceptance of valid data • Normalisation to standard conditions of pressure and temperature (0º C and 1,013mbar) and correction under dry conditions and a determined percentage of O2 • • • • • • • • • • Monitoring and status display Combustion processes Cement plants Monitoring of turbogenerators Thermal and combined cycle power stations Cogeneration plants Waste incineration Refineries and chemical plants Waste water treatment plants Measurement of VOCs SADEC connection interfaces for emission control • RS232 interface with Modbus RTU protocol • DB9 serial connector cable socket • Maximum number of connections: 1 • Maximum distance < 20 metres • RS485 interface with Modbus RTU protocol • DB9 serial connector cable jack • Maximum number of connections: 32 • Maximum distance < 1000 metres • CSV interface • Data reading from CSV files created by PLC (communication via FTP) or by the client • OPC interface to read, store and display data easily • RJ45 CAT 5/6 cable • Maximum distance < 100 metros (or more by the installation of a switch, up to a maximum of 3 units) • If the distance is greater, the connectivity has to be by multimodal/unimodal optical fibre • Reading of analogue signals by headers with 4...20mA cards • Single-line cable to read 4…20mA signals • Maximum distance < 500 metres Minimum requirements Operating System Processor RAM File system Disk space Interfaces Voltage Screen resolution Historical Windows XP/Vista Pentium at 1 GHz or equivalent 1 GB Minimum NTFS > 1 Gb 2x RS232 1x RS485 2x Ethernet RJ45 4x USB 2.0 DCF 77 card with BNC socket for time synchronisation (optional) 115/230 VAC / 50/60 Hz / 100 VA 800x600 Comprehensive monitoring to control emissions • • Filtering of consultations by days, hours and minutes • The intervals of minutes or hours to be displayed can be specified • With SADEC you will enjoy the following benefits: • Dynamic tables • Creates tables sortable by any column • The colour of the columns can be changed • Can be viewed with standard and customised units Easy configuration and operation • Intuitive and simple operation by menus and graphical icons • Customised configuration depending on the type of connection Customisation of consultations Graphics Reports • Features • Lines to display the values measured; maximum, minimum and mean values • Zoom available • Data can be exported for processing • Customisation • The colour of the lines can be changed • There is the option of changing the layout of the on-screen graphics • Creates pdf files • Creates Excel files • Exporting • Images can be created from the graphics Alarms • • • Customisation • The configuration of the various alarms for each parameter reading can be changed, depending on the value, mean value or data validity bit. Alarm log • Features • The start and finish times of each alarm is recorded since the program started • • All the important program events are displayed (errors, creation and/or file transfer, backups, etc.) with the date on which they occurred Features • The alarms are displayed, grouped according to the area affected, along with the length of time they have been active Filters • The results can be filtered by date, area affected and alarm status Events log • Customisation • The colours of the events can be changed according to type • Filtering by date, event type, instance, etc.
