Alocter 5G / 4G ultra-low power DTU / RTU helps water conservancy monitoring application upgrade

Release time:2020-04-27 17:23:00Click:



China attaches great importance to the monitoring of river hydrology. On the basis of the original water level monitoring points, various hydrological monitoring stations around the country have established some unattended hydrological monitoring points to monitor a wider range of hydrology and water conservancy conditions, including flow Water surface height, water quality, flow, tide level, precipitation and other parameters. Through the data collection unit and wireless transmission and network communication system set up in each hydrological monitoring point, the hydrological information searched by each monitoring point will be transmitted to the Water Conservancy Bureau or flood control headquarters in time for flood control scheduling decision-making.


Using Alocter 5G / 4G ultra-low power DTU / RTU wireless communication system to realize remote monitoring of hydrology and water conservancy is an ideal solution. The data collected by the Alocter ultra-low power DTU / RTU terminal is sent to the hydrological and water conservancy monitoring and management center through the 4G / 5G wireless network, which will greatly improve the collection, transmission and processing methods of hydrological information, shorten the data collection and forecast Time, improve the reliability of information collection and transmission, and improve the capacity of watershed flood control information processing.


Application background



The locations of water conservancy monitoring and deployment are mostly located in remote suburbs, and the wild rivers do not have power supply equipment. Therefore, most of the collection sites use solar power, storage batteries and other power supply methods without wiring. In this deployment environment, the equipment still needs 24 hours of uninterrupted operation and real-time communication transmission, which also greatly limits the power consumption of digital transmission equipment. AD2066L adopts the design concept of ultra-low power consumption and high reliability, which reduces the power consumption of the device without affecting the stability of the device transmission and operation, which greatly saves the cost of electricity and the cost of power supply equipment.


Features and advantages



  • The device power consumption online communication is less than 0.09W, and the average big data communication is 0.4-0.6W. It can meet the low-power environment powered by solar energy.

  • The cost of electricity is effectively saved. Correspondingly, the cost can be further reduced by reducing the area of the solar panel or the battery capacity.

  • Get rid of the limitation of geographic space, you can set up an automatic monitoring station in any place with wireless signal.

  • High-standard industrial-grade wireless communication equipment adapts to extreme weather and environment, effectively ensuring the stability and reliability of meteorological data.

  • The equipment is simple to operate and easy to install and maintain, without professionals, making on-site installation and commissioning personnel easy and efficient.

  • The cost is low and the operating cost is reduced.

  • Meet 5 ~ 35VDC wide voltage, -40 ~ + 80ºC cold and high temperature resistance, anti-interference, 24 hours a day


Solution topology



System Overview


The water conservancy online monitoring system is composed of a monitoring central station and a number of sub-stations with scattered points. Water conservancy data collection equipment collects and analyzes on-site collection indicators, connects with GPRRS / 3G / 4G data transmission equipment, and transmits the data back to the monitoring central station in real time through the wireless network. And take corresponding countermeasures.


Front-end: The detection, analysis and collection indicators mainly rely on the corresponding water conservancy data collection terminal and other professional instruments. The terminal communication interface is connected to the GPRS / 3G / 4G wireless data transmission equipment.


Communication: AD2066L's high-standard industrial-grade anti-jamming stability characteristics ensure that DTU can communicate with the water conservancy monitoring center in real time.


Backstage: The water conservancy monitoring center uses the Internet to organize and analyze the information and status of all DTUs in the front end, and then take corresponding measures.
