Near-earth atmospheric fault monitoring system and method

Abstract

The invention discloses a near-earth atmospheric fault monitoring system and method. The system comprises a vertical rod, wherein a lifting platform which is disposed on the vertical rod and can move up and down on the vertical rod, a plurality of pollutant sensors disposed on the lifting platform, a meteorological parameter sensor, and a main controller which is electrically connected with the pollutant sensors and the meteorological parameter sensor; the control room can remotely control lifting of the lifting platform, NFC cards for transmitting signals are arranged on the vertical rods at intervals, and NFC card reading equipment is installed on the lifting platform. Monitoring data of the pollutant sensor and the meteorological parameter sensor are wirelessly transmitted, processed and displayed in the lifting process of the lifting platform, and air quality monitoring at all heights within the height range of 30 m can be achieved only through one monitoring device. Through remote control, constant-speed up-and-down periodic motion is achieved, the speed of the lifting platform installed on the monitoring vertical rod is adjusted, special measurement can be conducted on the specific height, meteorological parameters such as the wind speed and the wind direction are fused, and data correction can be conducted on pollution distribution.

Description

technical field [0001] The invention relates to the technical field of atmospheric monitoring, in particular to a near-earth atmospheric fault monitoring system and method. Background technique [0002] At present, in the field of atmospheric environment monitoring, there is an urgent need for high-precision fault monitoring at low altitudes below 30m, and this altitude range is also the area where people live and live the most densely. The value it brings can be used to guide the establishment of sampling heights for standard stations , Monitoring of dust accumulation on the leaves of street trees, investigation of low-altitude pollution sources, improvement of housing and living environment, and many other fields. So far, the mature technologies at home and abroad can be divided into the following three types according to the monitoring principles: 1. Using external forces such as airplanes and tethered balloons to bring the sensor to a specified height range, such as "Ver...

Problems solved by technology

So far, the mature technologies at home and abroad can be divided into the following three types according to the monitoring principles: 1. Using external forces such as airplanes and tethered balloons to bring the sensor to a specified height range, such as "Vertical Multi-layer Observation and Analysis System for Pollutants in the Air" Patent No. CN201220365520.9, the method adopted in this patent can realize multi-point vertical distribution monitoring, but it is limited by the airflow disturbance at the bottom of the large helicopter and the long sampling tube has obvious data lag, the monitoring site needs to be particularly open and cannot be monitored for a long time

2. Relying on the existing buildings and taking advantage of their height, place monitoring equipment at the required height respectively. See references and see "TSP, S0 in the atmosphere 2 The vertical distribution law of the near-ground concentration", the limiting condition is that it needs to rely on existing buildings and other scenarios cannot meet the requirements, and the building itself affects the wind speed and direction in the small environment, etc.

3. Use lidar to measure the sky’s exposure. See Patent No. CN201610880483.8 of "Lidar-Based Monitoring Method for Vertical Distribution of Atmospheric Space Particles". , it is impossible to monitor effective data within 50m. The hardware cost of the equipment is extremely high, and the operation is difficult
