Abstract

In China, energy companies need to use CEMS (continuous radiation monitoring system) to monitor atmospheric pollution. Environmental protection department to use the power of the data analysis in order to monitor and control pollution of the atmosphere. The new system includes CEMS Advantech's UNO-2160, ADAM-5000/485 and ADAM-4000 modules will be operated by the analysis of reliability and accuracy of data together.

1.System Requirements

The Chinese government is gradually carried out the work of air pollution regulation. One is to require each energy enterprises to establish a CEMS to monitor air pollution emissions. This particular user has been using an outdated system of the IPC, as the data inaccurate, unreliable operation, led to many problems.

Customers want the chimney emissions for each real-time monitoring of conditions, including smoke, carbon dioxide and they want to stack emissions for each real-time monitoring of conditions, including smoke, carbon dioxide and other chemical ingredients. In addition, all records need to send the data to the control center of the environmental protection department. They hope to have a reliable system as a data terminal for data analysis, storage and effective distribution.

2.Project implementation:

• UNO-2160: Celeron 400 MHz Universal Network Controller with PC/104 expansion
• ADAM-5000/485: 4 slots RS-485 network of distributed data acquisition and control system
• ADAM-5017：8-Channel Analog Input Module
• ADAM-5050：16 general-purpose digital I / O module
• ADAM-4017+：Of 8 with Modbus Analog Input Module
• ADAM-4050：Volume of 15 digital I / O module

4.System Description:

The CEMS uses Advantech's ADAM-5000/485, ADAM-4000, ADAM-5000 and UNO-2160 module. ADAM-5017 and ADAM-4017 + module as a data collection receiver to connect to all of the flue and the work, collecting temperature, humidity and pressure data. Through third-party analysis of the sensor instrument will collect, analyze data on TOC and CDO. Abnormal situations encountered, ADAM-5050 and ADAM-4050 will report to the police and control valve. As a data processor, UNO-2160 will access the data storage and data sent via modem to the environmental protection department of the central server.

5.Summary

Thermal power plant is very harsh working environment. Fortunately, UNO-2160's solid, non-fans, and compact design features to meet the application of such an environment. Its high reliability, reduced operating costs of future maintenance, In addition, it supports the common programming languages, such as VC and VB, and thus can make it easier for engineers to use. ADAM-4000 module integrates Modbus and ASCII, for direct communication. CEMS a new collection of the UNO-2160, ADAM-4000 and ADAM-5000 module, able to offer our customers more reliable, accurate and efficient service.
