DISTRIBUTED CONTROL SYSTEM FOR BUILDING ECOLOGY

摘要

Disclosed is an intelligent distributed control system for implementing power-saving running of a heating and air-conditioning system device in a modern building. The whole distributed control system comprises two-stage control loops, namely, a central control loop and a regional control loop. A central control cabinet sends a control instruction to a central air-conditioning device through a master bus, so as to form the central control loop. A regional controller in each region adjusts, through a correspondingly connected communication repeater, the working state of a terminal air-conditioning execution device by using multiple regional control instructions output from an executor bus, so as to form the regional control loop. This system product can implement, through multi-point exchange running control between users and the building, systematic adjustment of power-saving running such as dynamic time and region division control of heating and air-conditioning loads for the building, low power consumption in an unattended area, frequency conversion running of the central air-conditioning device, and system climate compensation response.
