Real-time monitoring and early warning system and method for individual work dust concentration exposure spatial law

Abstract

The invention discloses a real-time monitoring and early warning system and method for individual working dust concentration exposure space regularity, which includes a dust concentration sensor network, a cloud server and a protective clothing positioning wearable device; the multivariate linear method is used to calibrate the dust concentration sensor at each position; Then the cloud server combines the dust concentration values ​​detected by each dust concentration sensor with their respective location information, and after a comprehensive analysis, obtains the spatial distribution of dust concentration in the workplace, and divides the area exceeding the threshold in the workplace space according to the set dust concentration threshold. It is defined as an overrun area; finally, the protective clothing positioning wearable device sends the location of the staff in the site to the cloud server in real time, and the cloud server compares each real-time position information with the real-time overrun area. If it is in the real-time overrun area, Then the cloud server sends an alarm signal to the protective clothing positioning wearable device to make the sound and light alarm alarm to remind the worker that the dust concentration exceeds the limit.

Description

technical field [0001] The invention relates to a real-time monitoring and early warning system and method for individual work dust concentration exposure spatial regularity, belonging to the field of work dust exposure monitoring and early warning. It is especially suitable for monitoring and early warning of respiratory and lung diseases caused by inhalation of work dust in construction, wood processing, metal processing, mine operations and other job sites that are exposed to high concentrations of dust and have high occupational health risks. Background technique [0002] The generation of dust is an unavoidable factor in industrial production operations, which poses a huge threat to the respiratory and lung health of workers during the operation. Staff who work in high concentration of dust for a long time are prone to occupational diseases such as pneumonia, lung cancer and pneumoconiosis. Therefore, it is extremely necessary to monitor the dust in the workplace where...

Problems solved by technology

However, because the light scattering method is easily interfered by external factors such as atmospheric temperature, relative humidity, and wind speed, the possibility of its direct application to real-time monitoring of individual workers and the overall dust concentration of the workplace is limited.
