Odour Monitoring

1.Odour Monitoring Function Requirements

Odour Monitoring is an odor monitoring system that monitors odor concentration OU value, ammonia, hydrogen sulfide and other malodorous gases.Intermittent monitoring or environmental odor monitoring is carried out for polluted areas for 24 consecutive hours.Standard monitoring indicators can simultaneously achieve the types of pollutants specified in the GB14554 standard: odor concentration OU value, ammonia, and hydrogen sulfide.

2.Odour Monitoring detection part

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

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

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

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

3.Odour Monitoring display control system

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

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

Built-in parameter settings, with sensor pre-maintenance function, which can promptly remind customers to maintain the sensor.

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

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

4.Odour Monitoring Communication System

The Internet of Things access server adopts a professional communication SOC processor, dual-core and four-thread, with a main frequency of up to 880MHz, and is equipped with large-capacity Flash 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 meet industrial standards, support wide voltage inputs of 9~36V, 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 through 4G wireless and wired 485, and can be optionally viewed and monitored data in real time through computer web pages or mobile APPs.

Supports cloud data storage.It can also realize the concurrent transmission function of multiple servers, and can support up to 3 platforms for direct upload.The analyzer supports the connection between the HJ212-2017 network protocol and the data management platform.

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

5.Odour Monitoring Preprocessing Part

It has insect and large particulate filtration, dust filtration and water vapor filtration, which can effectively filter oil, gas, water vapor, dust, etc.in the sample gas, effectively reduce interference during the monitoring process, and more quickly, efficiently and accurately unique gas circuit design, effectively solve the interference between gas sensors, and ensure that the sensor works in a steady-state environment.

6.Odour Monitoring Chassis Part

Vertical pole manufacturing process: equipped with lightning rods and grounding: lightning rods are arranged on the top of the pole.The combination of segments is convenient for logistics and transportation.

The entire chassis is made of outdoor plastic powder, and is plasticized at 180° high temperature.The coating has excellent appearance quality and the coating has much higher corrosion and wear resistance.The overall appearance is stable, generous and thick, and has a high load-bearing strength, which solves the problem of serious pole shaking in severe weather such as strong winds.Waterproof level IP53 or above, safe use in outdoor environments.
