The system comprises a runoff simulation and control host basedon a GIS, a meteorological forecast and runoff satellite monitoring server, a distributed small meteorological station, a vertical surface rain condition monitor, a movable rainfall radar, an infrared video monitor, an evaporation measuring instrument, a rainwater pipe network flow monitor, a water quality online monitor, an air quality monitor, a radar rainfall monitor, an infiltration area saturation monitor, an accumulation area water level monitor, a shallow-layer underground water level monitor, a surface runoff monitor, a waterproof unmanned aerial vehicle with a speed measuring buoy, an optical fiber temperature sensing system, an optical fiber pressure sensing system, a communication module, an intelligent controller, a rainwater utilization facility water supply point, a high-position rainwater hydroelectric generation module, a submersible conveying pump, a pressurization infiltration device and the like. According to various parameters, the rainfall flood disasters are subjected to scientific early warning and warning, and measures are adopted, so that the disaster risk of rainfall flood disasters to a building area or a building can be reduced.

An air quality monitoring arrangement is associated with an enclosed cab of an agricultural tractor used for towing or carrying spraying implements for treating crop with substances which might be toxic or otherwise harmful to people. A signal from a contaminant sensor is sent to a control arrangement which compares the actual sensed contamination of the air within the cab over time with a value from a performance map representing the performance expected from normal performance of the air circulating system of the cab. When the sensed contamination is higher than that of the performance map the operator is warned of a malfunction. The blower of the air circulating system may have its speed increased so as to pressurize the cab so as to exclude the entry of contaminated air through seals and other small openings of the cab. The air filters used are coded and recognized by the control system which keeps track of the service time of the filters and warns an operator when the service time exceeds that of a stored time value related to the particular filter.

The invention discloses an open type air quality monitoring system, relates to the technical field of air quality monitoring, adopts a movable low-cost air quality detection terminal, combines an opentype big data system architecture, perfects an existing air quality monitoring network, reduces the cost of the air quality monitoring system, and realizes data sharing to the maximum extent. A dynamic intelligent air prediction algorithm is adopted, the advantages of large air quality detection equipment and a common air quality detection terminal are fused, and real-time prediction of the air quality of a specific position is achieved; meanwhile, an automatic calibration technology based on a moving position is adopted, so that the precision of the air quality monitoring system is improved;it is achieved that the air quality of the current position is inquired in real time by ordinary residents through the Android App technology and the Web technology, the hysteresis and regional defects in air quality forecasting are overcome to a certain extent, and a new solution is provided for accurate forecasting of the air quality.
