Roof greening rainwater detention storage monitoring system and monitoring method

Abstract

The invention discloses a roof greening rainwater detention storage monitoring system and monitoring method. The system comprises a plant box, a drainage weight measuring module, a soil moisture measuring module, an environmental parameter collecting module and a control module; the drainage weight measuring module is connected with the plant box; and the control module is connected with the drainage weight measuring module, the soil moisture measuring module, and the environmental parameter collecting module. The roof greening rainwater detention storage monitoring system and monitoring method of the invention can be applied to high-density hot and humid climate regions. With the roof greening rainwater detention storage monitoring system and monitoring method adopted, the various relevant parameters of different roof greening plants under different rainfall types (light rain, moderate rain, heavy rain and storms) over a long time can be monitored; and data support can be provided forthe implementation of research on the influence of the rainwater detention storage of different roof greening plants and the matrixes thereof, the exploration of roof greening patterns suitable for high-density hot and humid climates, the alleviation of the pressure of urban pipe networks and the research on roof greening rainwater detention storage in sponge cities.

Description

technical field [0001] The invention relates to an environmental monitoring system, in particular to a roof greening rainwater storage monitoring system and a monitoring method, belonging to the field of roof greening. Background technique [0002] At present, Germany is considered to be the leading country in roof greening technology in the world. About 14% of the roof area has been greened. In 2006, Germany had 72-90 million square meters of green roofs. In addition, the practice of roof greening projects in developed countries such as Canada, Germany, the United States, Japan and my country's Hong Kong, Macao and Taiwan regions has reached a certain level. The research on roof greening system technology in these countries and regions mainly includes waterproof technology and water supply and drainage system, soil and root treatment and planting substrate selection, plant selection, greening methods and modularization. [0003] As for the domestic situation, in the 1980s,...

AI Technical Summary

Problems solved by technology

When a rainfall event occurs, almost all the rainwater runoff from sloping roofs, 90% of the rainwater runoff from flat roofs, and the rainwater runoff from urban impermeable roads will all be discharged into the urban drainage system, which will easily cause the drainage pipes to fail due to excessive pressure. Timely, leading to the occurrence of urban flood disasters

Roof greening, as a kind of urban green infrastructure, reduces the total runoff and the peak runoff generated by rainfall through the effects of vegetation layer conservation and matrix layer stagnation. One of the strategies for urban waterlogging, but there is still a lack of monitoring systems to provide data support for roof greening rainwater storage research
