The scientific construction of urban sewers is related to urban drainage, beautification, safety and other aspects.It is an indispensable and important infrastructure for urban production and life.The intelligent monitoring system of urban sewers uses wireless communication technology to monitor the state of sewers in real time.Under the intelligent management, the potential safety hazards such as urban waterlogging and well cover movement are comprehensively solved.
Various sensors are installed in urban sewers to monitor sewer water level information, surface temperature and humidity information, manhole cover status information (Displacement, opening and closing, loosening, etc.), which are transmitted to the Internet cloud platform through m2m modems.And can automatically give an alarm when that state of a certain part is abnormal.City managers can easily access relevant data through the cloud management platform, and judge the location of congestion through data analysis.By using this system, it is easier to grasp the information of all aspects of the city, thus greatly reducing the workload of city managers.
Perception layer: the sewer is equipped with temperature and humidity sensors, water level meters, acceleration sensors, etc. To monitor the water level, environment and manhole cover status of the sewer.Position for data monitoring.
Transport layer: m2m modem, connected to front-end sensor for real-time data acquisition and transmission.
Application layer: cloud platform receives transmission data, online real-time monitoring, abnormal data alarm,Ensure that management staff deal with problems in a timely manner.
Industrial grade high temperature resistant, cold resistant and anti-interference design, super gain antenna, all Netcom network communication.Special protection self-check mechanism, three-level watchdog detection mechanism, permanent online without packet loss, stable and reliable operation in the sewer;Support mains supply and solar power supply;It supports standard RS232 and RS485 interfaces, embedded PPP, TCP/IP, UDP/IP, MODBUS-TCP, MODBUS-RTU and other protocols.And that requirement of transparent transmission of sensor access and network access data are met.
