Control for industrial smoke on-line monitoring system and data transmission system and method

Abstract

The invention includes following subsystems and procedures: smoke-dust monitoring subsystem for monitoring concentration of smoke-dust in real time; subsystem of monitoring parameters of fume emission in use for detecting parameters including oxygen content, flow rate, pressure, and temperature in real time; subsystem of monitoring gaseous pollutant in use for sampling and controlling fume to carry out pretreatment; system control and data acquisition process subsystem in use for collecting signals output from the said subsystems, carrying out processing, storing, displaying, recording and statistical operations to implement transferring data in real time remotely; communication between program controlled pretreatment for fume and computer in central station of monitoring environmental protection. Using modern techniques such as sensor, detection, computer, network etc, the invention possesses advantages of high automation, good stability, quick processing and low operating cost.

Description

technical field [0001] The invention belongs to a data processing system for controlling industrial smoke, in particular to a control and data transmission system for on-line monitoring of industrial smoke. Background technique [0002] At present, people are paying more and more attention to the quality of the environment. The environmental protection department expects to control the emission of dust from various industrial enterprises through strict management and assessment. However, most of the emission monitoring of industrial dust is still in the state of manual regular monitoring. Even though some enterprises have installed online flue gas monitoring systems (CEMS), most of them have a low degree of automation and high maintenance costs, and basically only stay on-line monitoring within the enterprise, and cannot realize the real-time transmission of on-site detection information to the environmental monitoring department. It makes it difficult for the environmental ...

Problems solved by technology

If a high-power antenna is used, the communication distance can be increased, but the advantages outweigh the disadvantages. First, the site environment of industrial enterprises is harsh, and a large number of houses and kilns and other facilities will block or affect the transmission of FM signals; Diverse electromagnetic interference, plus many base stations generating radio frequency interference

If the Internet method is adopted, the overall reliability of the system will be affected due to the many links of intermediate equipment; the problem of laying cables is also unavoidable
