Abstract

The invention discloses a user type intelligent heat supply system based on DCS control and a control method. Compared with a traditional central heating system, a heat supply user terminal is additionally arranged on a heat supply main pipeline of each household, a terminal executing mechanism is an electric adjusting valve, and the terminal uploads user setting and the real-time opening degree of the adjusting valve to a public network through a 4G network. Equipment signals of the heat supply initial station and equipment signals of the heat exchange station outside the plant are connected to an on-site DCS control cabinet, and the control cabinet uploads the signals to a public network. The heat supply network dispatching center receives signals from the heat supply user terminal and the DCS control cabinet in the mode that the upper computer is connected into the public network, data analysis and processing are conducted through DCS control software, and then control signals are transmitted to the DCS control cabinet of the heat supply initial station and the DCS control cabinet of the heat exchange station outside the plant through the public network. Information of the heating system is transmitted through the public network, the DCS is used for controlling related equipment, and centralized management and scheduling of the heating network are achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of thermal power plants, and relates to a user-type intelligent heating system and a control method based on DCS control. Background technique [0002] With the advancement of industrialization and urbanization, the problem of environmental pollution is becoming more and more serious with the gradual increase in energy demand, especially in the northern region where long-term heating in winter is required, while ensuring the basic living needs of residents, it is necessary to achieve energy saving, emission reduction and fog prevention. haze. As part of the non-central heating method with high pollution and low thermal efficiency, it has been phased out. [0003] The mainstream central heating system control scheme generally adopts a comprehensive adjustment method, that is, through the control of the circulating pump and valve and other equipment in the first heating station or the off...
