Abstract

Applications in the environmental protection industry, we have many successful applications such as river water quality in our field monitoring system, IPPC and ADAM5510EKW/TP controller, multi-serial port cards can be a good match with the achievement of data acquisition and process control.

1. System Requirements

• To capture accurate and timely early warning signals and report timely and accurate
• Data, reports, inquiries
• Monitor and control workflow
• Data, reports, inquiries
• Monitor and control workflow
• GSM wireless data upload and alarm messages

2. System Function Description

Field Control System is the hardware platform IPPC9150, through the co-ordination of MCGS configuration software, monitoring 5510EKW/TP run, control the water quality analyzer and collected online data, collected through JBus bus protocol COD, DOC, COT analysis equipment, such as online data achieve MODBUS / GPRS wireless data upload and GSM SMS report to the police, as well as information collected river features such as velocity profile, complete the statements, the calculation of water quality, on-site automatic measurement of process control, as well as the completion of automatic reporting to the Central Station and transfer the task information. At the same time, because the system needs more communication serial port, serial port must be expanded: the adoption of the PCI expansion slots IPPC, we insert a PCI-1625U board, the eight serial port expansion, so that the serial number can be used to achieve 11 , and fully meet the water quality monitoring program of serial communication needs.

3. System Architecture

Control Center using PC-BASED PLC--ADAM5510EKW/TP + IPPC composition. There are a number of simulation of the lower volume of the collection, and give full play to the advantage of 5510EKW/TP, the control center through telephone lines or GPRS Remote Monitoring

Is in line with the IEC61131 standard 5510EKW/TP soft logic controller, it is the rise in recent years, PC-based architecture PLC, IEC61131 Industrial Control as a unified standard has been progressively network programming not only to control highly complex industrial processes can also be control functions and information management functions into one, and industrial control computers, distributed control system, embedded computer, such as further integration, the realization of large-scale comprehensive automation.

IPPC-9150 is a 15 "Pentium3 full-featured industrial grade Panel PC. It supports a variety of levels of CPU (Pentium3 to 850MHz, Celeron to 700MHz), fully meet the current needs of industrial software applications. IPPC-9150 is a solid Tablet PC-based industries, it comes with a aluminum alloy front panel, tempered glass to protect 15 "TFT LCD, stainless steel chassis and two expansion slots. IPPC-9150 has these features so that it can work in a variety of harsh environments use. Advantech also provides the installation from the悬壁, rack-mounted panels installed on the installation of optional accessories, the user can according to their own needs to be installed in any place.

4. Software Description

MCGS configuration software configuration through a friendly user interface, in the main interface can be seen on the main tank of the liquid level, valve status, temperature, conductivity, alarm and so on, there are other interface real-time monitoring, parameter setting , system maintenance and so on, parameters can be directly entered above in the IPPC, modify parameters, alarm sound and light alarm function can be the first to respond, and through GPRS or a remote monitoring center to inform MODEM. MCGS contains more than 1500 kinds commonly used drive, it will be convenient and PC-BASED PLC communications and remote control equipment.
