Automatic control system and method of heat exchange station

Abstract

The invention belongs to the technical field of control systems of heat exchange stations, and discloses an automatic control system and method of a heat exchange station. The control system used in the method comprises a temperature regulation and control device, a circulating system automatic control device and a water replenishing regulation and control loop automatic control device of the heat exchange station, wherein temperature ends of information acquisition modules of the three control devices are connected with temperature sensors on a heat exchange unit; pressure ends of the information acquisition modules are connected with pressure sensors on the heat exchange unit; output ends of the information acquisition modules are connected with a touch display screen through an analytical processing module; the analytical processing module is connected with a primary side electric regulation valve, a pressure release valve and a water replenishing valve through control modules; pump actuating ends of the control modules are connected with circulating water pumps on the heat exchange unit; and frequency conversion ends of the control modules are connected with water replenishing pump frequency converters and circulating water pump frequency converters. Thermodynamic equilibrium of a heat supply network is guaranteed, a heat supply system can run safely and reliably, and remote monitoring under the unattended condition is realized.

Description

technical field [0001] The invention belongs to the technical field of heat exchange station control systems, and mainly relates to a heat exchange station automatic control system and method. Background technique [0002] Central heating is an energy-saving and environmental protection measure vigorously promoted by the state. With the continuous expansion of the scale of urban central heating, scientific management of heat pipe networks has very significant economic and social benefits. The heat exchange station and the hot water pipe network are important links connecting heat sources and heat users, and play a pivotal role in the entire heating system. [0003] The current heating system in my country is relatively backward, which is specifically reflected in the poor quality of heating, that is, the uneven temperature of the room temperature, the low system efficiency, and the user cannot set and adjust the room temperature by himself; there is a lack of control means, ...
