Odor Online Monitoring System

1.Odor Online Monitoring System Functional Requirements

Odor Online Monitoring System combines various odor gas parameters to grasp the odor emission concentration and rule of the monitoring site in real time.Intermittent monitoring or continuous 24-hour environmental odor monitoring of polluted areas. The 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, and carbon disulfide.

2. Odor Online Monitoring System Detection

The monitoring system is composed of a mixed array of multiple sensors, and the sensor types should include metal oxide sensors, PID photoionization detectors, electrochemical sensors, and ETO sensors.

Each sensor can be plugged in and out individually, and can be calibrated and replaced individually.

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

When using a multi-sensor array, 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 System display control system

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

This machine can display historical concentration curves, directly showing data changes and component proportions in the form of charts, and real-time data analysis to help with event judgment.

Built-in parameter settings and sensor pre-maintenance function can remind customers to maintain the sensor in time.

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

The analyzer can easily upgrade its firmware, which can be achieved through a USB flash drive. The system can also perform remote one-key upgrades, parameter configuration modifications and other functions.

4. Odor Online Monitoring System Communication System

The IoT access server uses a professional communication SOC processor, dual-core and four-thread, with a main frequency of up to 880MHz and a large capacity Flash as standard. Based on a 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 are in line with industrial standards, support 9~36V wide voltage input, and the ambient temperature range can reach -20~65℃.

Supports Modbus communication protocol, can set up and communicate with the system. Data can be transmitted via 4G wireless and wired 485, and can be optionally viewed in real time via computer webpage or mobile phone APP.

Supports cloud data storage. It can also realize multi-server concurrent transmission function, and can directly upload to up to 3 platforms. The analyzer supports HJ212-2017 network protocol to connect with the data management platform.

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

5. Odor Online Monitoring System Preprocessing

It has functions of insect and large particle filtration, dust filtration and water vapor filtration, which can effectively filter oil, gas, water vapor, dust, etc. in the sample gas, effectively reduce interference in the monitoring process, and is faster, more efficient and accurate. The unique gas path design can effectively solve the interference between gas sensors and ensure that the sensors work in a steady state environment.

6. Odor Online Monitoring System Chassis

Pole manufacturing process: equipped with lightning rod and grounding: a lightning rod is installed on the top of the pole. The segmented combination is convenient for logistics and transportation.

The chassis is made of outdoor plastic powder sprayed as a whole, and is fixed at 180° high temperature. The coating has excellent appearance quality and is much more resistant to corrosion and wear. The overall appearance is stable, generous, and heavy, with high load-bearing strength, which solves the problem of severe shaking of the pole in bad weather such as strong winds. The waterproof level is above IP53, and it is safe to use in outdoor environments.
