2020-11-27 15:03:07 【Xu gaga】
With the continuous improvement of modern living standards , People have higher and higher requirements for the air quality of the surrounding living environment , The exhaust gas emitted by enterprises and factories mainly includes SO2、NO2、CO2、HF、 Dust particles, etc , These harmful gases will not only affect people's health, causing all kinds of inflammation , And long term exposure to such an environment may even cause cancer , Urban Haze will further cause global climate change , Not only affects the present but also destroys sustainable development in the future , The wanton emission of harmful smoke will cause immeasurable losses . therefore , The national government's smoke emission policy is more and more strict , The punishment for violating the regulations is also increasing , Flue gas online monitoring system is of great significance to both regulatory authorities and enterprises .
One 、 System principle
The flue gas online monitoring system built by Jixun IOT conforms to relevant national policies and technical standards , It has a wide dynamic range 、 Strong real time , Low operating costs, advantages , Pass the monitoring data through Data acquisition instrument The information transmitted to each sensor is uploaded to the data center . And be able to To the enterprise factory discharge SO2、NO2、CO2、HF、 Dust particles 、 Flue gas temperature 、 Flue gas pressure 、 Flue gas velocity 、 The data of oxygen content in flue gas is collected automatically 、 Analysis and storage , Automation , Real time , Accurately monitor and control the exhaust emission of the enterprise factory and the normal operation of the equipment . In order to achieve energy saving and emission reduction 、 Total amount control provides effective supervision means .
System topology ：
Two 、 System characteristics
Monitoring equipment ： The online smoke monitor has a cigarette end probe , Flowmeter , Pressure gauge , Temperature and humidity meter , Dust meter and other sensors , adopt RS485 The bus is connected to the smoke monitor .
Transmission network ： Install according to the actual situation on site , use 2G/3G/4G Wireless network communication mode into the network .
Remote control ： The administrator can remotely operate the smoke monitoring equipment through the network in the control center , Look at the data , Open and close operation and other configuration .
The monitoring center ： The real-time data of flue gas online monitoring is uploaded to the server through the network , Realize data collection 、 management 、 Inquire about 、 Statistics and the form of charts and other functions intuitive display .
Mobile monitoring ： It can be downloaded from mobile phones or other mobile devices APP, management 、 see 、 Inquire about 、 Opening and closing and other related operations , It can also manage the online monitoring system in the mobile .
3、 ... and 、 System composition
Data acquisition and logic control unit
The data acquisition instrument is used to calculate information TS910
Automatic control system
frequency conversion & Soft start system intelligent control cabinet
Temperature and humidity 、 Air pressure sensor
Smoke probe 、 Flowmeter 、 Dust meter
Four 、 Application platform
Environmental protection data acquisition equipment remote smoke monitoring Functional objectives
reliability ： equipment 24 Work 24 hours a day , It has remote diagnosis function , Data reissue function , Further ensure the integrity of all data , Automatic reconnection after dropping the line , Always online .
Informative ： Real-time monitoring , Oil fume online monitoring information is automatically collected and uploaded to the data center in real time , And save .
Security ： Encrypt the transmitted data , Secure data transmission , Refuse to be tampered with by interception .
mobility ： Monitors are no longer limited to control centers , The operator does not need to be on site and can be remotely PC/ Mobile terminals ( mobile phone )APP Remote monitoring , At the same time, auxiliary remote video can directly observe the operation of the scene .
adaptive ： Suitable for high dust 、 The high temperature 、 High humidity 、 Monitoring in various harsh environments such as unstable flow field .
Intuitiveness ： Add the data uploaded to the server into the database , And directly show the data and relationship to the administrator in the form of chart .
