Odor online monitoring equipment

1. Functional requirements forodor online monitoring equipment

Odor online monitoring equipment is also called odor online monitoring equipment and odor online monitor. Odor online monitoring equipment applies high-sensitivity sensor detection and analysis technology to monitor and analyze the concentration and intensity of odorous substances in the atmosphere in real time, and reflect it in the form of data. Intermittent monitoring or continuous 24-hour environmental odor monitoring for polluted areas. Standard monitoring indicators can simultaneously achieve the types of pollutant control specified in the GB14554 standard: odor concentration OU value, ammonia, styrene, hydrogen sulfide, VOCS, trimethylamine , methyl sulfide, methyl mercaptan, dimethyl disulfide, carbon disulfide.

2. Odor online monitoring equipment detection part

The monitoring system is composed of a variety of sensor hybrid arrays. The sensor types include metal oxide sensors, PID photoion detectors, electrochemical sensors, and ETO sensors.

Each sensor can be individually plugged and unplugged, and can be individually calibrated and replaced.

The instrument and equipment calibration operation function is available on-site, so there is no need to take it back to the laboratory for calibration.

When using a multi-sensor array layout, a working analysis curve that conforms to the artificial olfactory identification method should be established to simulate the human olfactory system.

3. Odor online monitoring equipment display control system

The 7-inch true color LCD touch screen is selected to display all real-time monitoring data and the system working status.

This machine can display historical concentration curves, directly display data changes and component proportions in the form of charts, and conduct real-time data analysis, which is helpful for event judgment.

Built-in parameter setting and sensor pre-maintenance function can remind customers to perform sensor maintenance in time.

The data record can reach at least 1,000,000 items, with built-in database and USB data copying capability.

The analyzer's firmware can be easily upgraded via a USB flash drive. The system can also perform remote one-click upgrade, parameter configuration modification and other functions.

4. Odor online monitoring equipment communication system

The IoT access server adopts a professional communication SOC processor, dual-core and four-threads, with a main frequency of up to 880MHz and a large-capacity Flash as standard. Based on the powerful hardware platform, feature-rich software can be implemented to meet diverse monitoring applications. The deeply customized JYun operating system supports GPRS, RJ45, ZigBee, LoRa, WIFI, NB-IOT and other communication methods. Flexible networking and secure data transmission. The motherboard and components comply with industrial-grade standards, support 9~36V wide voltage input, and the ambient temperature range can reach -20~65℃.

Supports Modbus communication protocol, which can set up and communicate with the system. Data can be transmitted via 4G wireless or wired 485, and monitoring data can be viewed in real time through a computer web page or mobile APP.

Support cloud data storage. And it can realize the concurrent transmission function of multiple servers, and can support direct upload to up to 3 platforms. The analyzer supports the HJ212-2017 network protocol to connect to the data management platform.

The system software has functions such as direct data transmission, data storage, statistical analysis, over-standard alarm, and point writing.

5. Pretreatment part of odor online monitoring equipment

It has insect and large particle filtration, dust filtration and water vapor filtration, effectively filtering oil, gas, water vapor, dust, etc. in the sample gas, effectively reducing interference during the monitoring process, and making it faster, more efficient, and more accurate. The unique gas circuit design effectively solves the problem between gas sensors. interference to ensure that the sensor works in a steady-state environment.

6. Chassis part of odor online monitoring equipment

Pole manufacturing process: Equipped with lightning rods and grounding: The top of the pole is equipped with lightning rods. The segmented combination method facilitates logistics and transportation.

The entire chassis is sprayed with outdoor plastic powder and molded at 180° high temperature. The coating has excellent appearance quality and much higher corrosion and wear resistance. The overall appearance is stable, generous, thick, and has high load-bearing strength, which solves the problem of serious pole shaking in strong winds and other bad weather. Waterproof grade IP53 or above, safe for use in outdoor environments.
