Efficient communication type heat exchange station building automatic control system

Abstract

The invention relates to an efficient communication type heat exchange station building automatic control system, which comprises a first station building terminal device, a second station building terminal device, an Nth station building terminal device, a DDC controller and a control center. The first station building terminal device is bidirectionally and electrically connected with the DDC controller, the second station building terminal device is bidirectionally and electrically connected with the DDC controller, the Nth station building terminal device is bidirectionally and electrically connected with the DDC controller, and the DDC controller is bidirectionally and electrically connected with the control center. According to the efficient communication type heat exchange station building automatic control system, through cooperation of the first station building terminal device, the second station building terminal device, the N station building terminal device, the DDC controller and the control center, networking can be used very conveniently, decentralized control is achieved, bidirectional direct data communication is achieved between the control center and the field controller, other transfer and control links are not needed, so that the consistency of transmission data is ensured, the time delay of data transmission is reduced, and the reliability of network communication is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange stations, in particular to an automatic control system for high-efficiency communication heat exchange stations. Background technique [0002] The heat exchange station is a place where heat is concentrated and exchanged. According to the heat supply form, it is divided into direct supply station and indirect supply station. The former is directly supplied by the power plant to users, with high temperature, difficult control, and waste of heat energy. It is the product of the initial power plant waste heat welfare heating. . [0003] At present, the on-site control of the heat exchange station mostly uses the PLC controller or embedded board as the controller to control the terminal equipment. This control method is limited by the fact that the PLC does not have a mature operating system, and most PLC suppliers rely on The simple assembly system built into the microprocessor completes the c...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a high-efficiency communication heat exchange station automatic control system, which has the advantages of improving network communication, etc., and solves the problem that PLC has poor network functions and must rely on PC or special gateway to form a network ;Since there are few analog control modules in PLC, and the parameters are difficult to modify, in many cases it is necessary to borrow expensive special PID control modules. When the control is not complicated, it is necessary to use PC to provide calculation control.
