Built-in programmable logic control function and timer function. Through the data collection and control of the BLIIoT Environmental Monitoring RTU, a series of purposes such as optimizing energy consumption, improving processes, increasing efficiency, and reducing costs can be achieved.

Next, we will introduce you to several common application scenarios.

01

Pollution source monitoring

In the pollution source online automatic monitoring system, the BLIIoT 4G Environmental Monitoring RTU plays an important role in data connection and communication. It can connect various sensors, actuators and other environmental protection equipment to realize data collection, transmission and control. For example, the smoke and dust online monitoring system collects flue gas monitoring information such as desulfurization, denitrification, and dust, and implements statistical analysis functions.

 

 

02

Farm monitoring

BLIIoT 4G Environmental Monitoring RTU collects CO (carbon monoxide), H2S (hydrogen sulfide), O2 (oxygen), ammonia, air temperature and humidity, light, soil temperature and humidity, carbon dioxide, etc., and controls fans, light bulbs, and wireless data transmission to platform. It can be widely used in monitoring the environment of various farms such as pigs, chickens, ducks, cattle, geese, and sheep.

 

03

Greenhouse monitoring

In the application of environmental monitoring in smart greenhouses, it mainly collects and monitors illumination, air temperature and humidity, soil temperature and humidity, soil pH, carbon dioxide, etc., and controls roller shutters, fans, etc.
 

 

04

Industrial wastewater treatment monitoring

The wastewater remote monitoring system consists of a control center and remote control terminals RTU at hundreds of monitoring points scattered in various departments of the factory. The RTU regularly transmits the data of the monitoring point (including the discharged wastewater flow value, wastewater treatment equipment operating time, etc.) to the control center through the 4G network, enters it into the database, and accumulates the entered discharged wastewater flow value and wastewater treatment equipment operating time in real time. . In addition, the control center monitoring personnel can check the actual operation status of various monitoring points scattered in the factory at any time.
 

05

Environmental monitoring and control

4G Environmental Monitoring RTU can connect to monitor environmental environmental data such as carbon dioxide, PM2.5, rainfall, wind direction, wind speed, noise, light, air pressure, temperature and humidity, and upload the data to the cloud platform for analysis and display. Based on these data, environmental monitoring, early warning and control can be achieved, such as automatically alarming when CO2 concentration exceeds the standard, adjusting the ventilation system to improve indoor air quality, etc.

 

06

Smart Meter Reading

Traditional meter reading relies on manual work, which has large errors, is not timely, and has high labor costs, which has greatly hindered the informatization process of the water and electricity industry. In the factory, it mainly collects electricity meters, water meters, gas meters, etc., and controls air conditioners, lights, exhaust fans and other equipment. 4G Environmental Monitoring RTU can remotely view the energy consumption of the factory and automatically control the energy-consuming equipment of the factory to save energy and reduce emissions.

 

All in all, wherever there are sensor and device data signal outputs, 4G Environmental Monitoring RTU can be configured and connected. 4G Environmental Monitoring RTU has a wide range of applications in real-time control, data collection, industrial automation and other fields. BLIIoT provides real-time, efficient and reliable data transmission and integration solutions for various industries, improving production efficiency and management levels.
