I. Industry situation

With the acceleration of the urbanization process across the country, high-rise buildings are springing up, and spacious and tidy streets are extending out one by one.Underground drainage pipes have been neglected for a long time. With the continuous expansion of urban scale and the continuous growth of streets, underground drainage pipes and river drainage are still primitive. A rainstorm can lead to poor urban drainage and serious water flooding.

As a smart Internet terminal solution provider integrating r&d and intelligent manufacturing in the Yangtze River Delta region, Mantu technology actively builds a set of "urban drainage monitoring and early warning system".The system can real-time online monitoring urban sewage water, culverts, water level, water level, river water level, etc., when these sites were immediately inform management platform, through the phone APP, mobile phone text messages, such as the sound and light alarm inform city managers, the broad masses of social danger, and for decision makers to develop a solution to the danger, achieve the goal of early warning, and mitigation.

III. Program features

High real-time performance: Real-time collection and transmission of data at all monitoring points to THE MTIC 3.0 cloud platform for data analysis and dynamic display through big data Kanban.

High security, high reliability: the system can effectively prevent and prevent network attacks such as illegal access, illegal access, virus infection and hacker attack, with a high degree of security and confidentiality;The system adopts mature, stable and general technology and equipment, which can guarantee the long-term stable operation of the system, and has strong fault tolerance and system recovery capability.

Linkage of water pump: support linkage of water pump and drainage pump, automatically realize the start and stop of drainage pump according to the change of water level at the monitoring point.

Early warning and intelligent analysis: The real-time collected data can be compared with the set threshold value, and the MTIC 3.0 cloud platform can give early warning, leaving sufficient time for relevant disposal personnel to eliminate security risks.

Automatic multi-stage warning: automatic alarm in case of water level/rainfall exceeding limit, equipment failure and abnormal power supply, uploading to monitoring center;Three-level warning for measuring points of water accumulation, pay attention to safety, communicate with caution and prohibit passage;Alarm thresholds such as water level/rainfall support custom Settings.
