Since 2010, Zhengzhou City Heating Co., Ltd has gradually built the "xLink heat network monitoring" system, this system is based on the VPN network built by the public communication platform, the core controller is the scu-3000- PRO, and the purpose of controlling the indoor temperature of the user is achieved by adjusting a return water valve to control the heat exchanger. The system has the advantages of high security and confidentiality, high speed, high reliability, high anti-interference ability, low cost and easy maintenance. So far, the system has realized the remote automation monitoring of 1219 thermal stations, and has been running seven heating seasons safely.

 In the same period, the software of the xLink command and dispatch system was adopted to construct the Zhengzhou heat network command and dispatch system, the system has realized the function of heat network scheduling management, climate model, heat source and thermal station prediction, task list, accident treatment and thermal network operation analysis. The system works well.
