This is a renovation project, which realizes remote monitoring by optimizing the system architecture.

The original system of the project uses the old system of Invensys. The project has a total of 21 floors, each floor has about 130 VAVs and 2 air conditioning units, and the construction has been more than 10 years. Considering the control of user transformation costs, we suggest that users do not need to replace new DDC and network controllers. On the basis of the original system, we re-repair the old system for the user, and optimize the old system software, the user interface that can only operate in the server in the past, re-optimize the network-based BS architecture, users only need to communicate in the network, you can remotely monitor the running status of the device through the computer browser.
