The Role and Significance of Odor Online Monitor in Industrial Zones

The Odor Online Monitor can perform both intermittent monitoring and continuous 24-hour environmental odor monitoring in polluted areas. Its standard monitoring indicators cover the odor concentration OU value, ammonia, hydrogen sulfide and other pollutant control types in the GB14554 standard.

The detection part adopts a combination of multiple sensor hybrid arrays, including metal oxide sensors, PID photoionization detectors, electrochemical sensors, ETO sensors, etc. Each sensor can be individually plugged, calibrated and replaced, and the calibration operation of the instrument and equipment can be completed on site without the need to return to the laboratory. When the multi-sensor array is arranged, a working analysis curve conforming to the artificial olfactory method can be established to simulate the human olfactory system and ensure the accuracy and reliability of detection.

The display and control system is equipped with a 7-inch true color liquid crystal touch screen, which can clearly display all real-time monitoring data and the working state of the system. It can also intuitively present the data changes and component proportions in the form of a historical concentration curve graph, facilitating event judgment. It has built-in parameter setting and sensor pre-maintenance functions, which can remind customers to maintain the sensors in a timely manner. The data record can reach 1,000,000 pieces, supports USB data copying, and the analyzer firmware can be easily and conveniently upgraded. It can be upgraded and parameter configurations can be modified with one key via a U disk or remotely.

The communication system adopts a professional communication SOC processor. Based on a powerful hardware platform and a customized JYun operating system, it supports multiple communication methods, such as GPRS, RJ45, ZigBee, LoRa, WIFI, NB-IOT, etc., to flexibly form a network and ensure secure data transmission. It supports the Modbus communication protocol, and data can be transmitted wirelessly via 4G or wired 485. It can be optionally equipped with a computer web page or a mobile APP for real-time viewing. It also supports cloud storage and multi-server concurrent transmission. It can be uploaded to a maximum of 3 platforms and complies with the HJ212-2017 network protocol to connect to the data management platform. The system software has rich functions.

The pretreatment part can effectively filter out insects, large particulate matter, dust, oil and gas, water vapor, etc. in the sample gas to reduce interference. The unique gas path design solves the interference between gas sensors and ensures the stable operation of the sensors. The pole manufacturing process of the chassis part is excellent, equipped with a lightning rod and grounding. The segmented combination is convenient for transportation. The overall outdoor plastic powder spraying of the chassis is subjected to high-temperature shaping. The waterproof level is above IP53, and the appearance is stable and has a large load-bearing strength. It can adapt to severe weather and provide reliable protection for the entire monitoring system.
