1. Project background
The city’s garbage disposal is first centralized collection, then the garbage is sorted, sent to the garbage treatment plant or landfill for centralized treatment, so these places become places with serious malodorous gas, which will affect the surrounding ecological environment and residents’ lives. It has brought great troubles. As an important part of environmental protection monitoring, odor monitoring is a major problem that needs to be solved urgently.
Two, system overview
The Environmental Monitoring System of Kexun Garbage Odor is specially designed for garbage disposal, sewage stations, fixed pollution sources, factory boundaries and other places prone to odor and odor. It can simultaneously monitor six kinds of gases including odor, plus outdoor environment PM2.5, PM10, and temperature. , Humidity, wind speed and direction, etc. dozens of parameters.
Through logical judgment and intelligent analysis, the malodorous gas level and alarm signal are output, so as to improve and enhance the remote monitoring and early warning capabilities of the atmospheric environment, and prompt environmental protection personnel to deal with it.
Three, system composition
The odor environmental monitoring system of the garbage dump is composed of front-end monitoring equipment, network transmission equipment, and remote management center.
1. Front-end monitoring equipment
Metal oxide sensors, electrochemical sensors, photoion monitors, meteorological five-parameter sensors, etc. It mainly monitors the malodorous and peculiar gas in the garbage dump in real time, collects various data and sends it to the communication bay.
2. Network transmission equipment
The front-end system processes the data collected by various sensors and monitors and transmits it to the monitoring center at a high speed through the 4G/5G wireless network.
3. Remote management center
The management center is responsible for unpacking the data uploaded at the communication interval layer, conducting centralized management and analysis, and performing related operations, such as issuing alarm messages and issuing control instructions to terminal monitoring equipment.
Four, system characteristics
1. Simultaneously monitor six kinds of gases including malodor, plus ten parameters of PM2.5, PM10, temperature and humidity.
2. You can select any time period for historical data query and curve display.
3. The environmental protection data acquisition instrument is compatible with TCP, IP, MODBUS and other communication protocols, and can wirelessly upload data to connect with the local environmental protection bureau.
4. Intelligent software wake-up and hardware power-off restart mechanism, reconnect after disconnection, data reissue, stable and reliable transmission without packet loss.
5. Abnormal alarm and event recording function, monitoring data exceeding the indicator can alert the staff through SMS, mobile phone, voice and other methods.
