Business Challenge

The company is a mixed-ownership enterprise from the Provincial State-owned Assets Supervision and Administration Commission in Asia. It is a one-stop solution provider of intelligent water conservancy and smart water projects, smart engineering, smart pipe network, smart operation, system integration and operation and maintenance management.

There is an identified need to monitor field data from hydraulic intercepting wells, but this raises the issues below:

  • The wired connectivity used on site is often cut off without warning for extended periods.
  • The geographic diversity and volume of sites makes physical monitoring costly.


  • At the site of the interception well, the customer embed a Schneider PLC, a Robustel R2000, and UPS power supply into an iron box, and the PLC is connected to a sewage valve (always open), rainwater valve (always closed) and a water level sensor. In terms of power supply design, the municipal 220V supplies Schneider PLC and UPS, and the UPS is separately supplied (9-36VDC) to the R2000.
  • The R2000 router connects to the Schneider PLC through the network cable and sets a DMZ, allowing the uplink plug in the telecommunication internal network card to obtain an IP address and communicate with the server and workbench in the remote main control room.
  • After the server in the main control room obtains an IP over optical fiber, it can then communicate with the R2000 of each intercepting well substation, and can collect the field sensor data read by the Schneider PLC.
  • After getting data from the server, the workbench in the main control room will feed data into monitoring software for each intercepting well site and perform counter-control (i.e. control the switch of sewage valve and rainwater valve).
