Detailed description of the invention
Shown in accompanying drawing 1, a kind of central heating control system, the control system comprising a secondary net, secondary network and be connected with a described secondary net and secondary network.The once pipe network water supply pipeline 1 that a described secondary net connects successively according to water (flow) direction, dirt separator 2, electric control valve 3, heat exchanger 4, calorimeter 5 and a pipe network water return pipeline 6; The thermal source of the flowing mainly steam that produces of thermo-power station and district boiler room or hot water in one secondary net, first enter a pipe network water supply pipeline 1 and carry out removing impurity by dirt separator 2, then arrived in heat exchanger 4 by electric control valve 3 and carry out heat exchange with secondary network, undertaken measuring in rear arrival pipe network water return pipeline 6 heat by calorimeter 5 again after heat exchange, return thermo-power station and district boiler room completes a circulation.What described secondary network connected successively according to water (flow) direction has secondary pipe network water return pipeline 7, dirt separator 8, water circulating pump 9 and secondary pipe network water supply line 10; The thermal source flowed in secondary network is water, enters subscriber household after first the water of cold conditions carries out heat exchange by the thermal source of heat exchanger 4 and a secondary net by secondary pipe network water return pipeline 7.Described control system comprises PLC 11, touch-screen 12 and frequency converter 13, and described touch-screen 12 is connected to PLC 11 and shows the data of PLC 11 output, and described frequency converter 13 is connected with PLC 11 and water circulating pump 9.PLC 11 is implanted into and presets various parameter, according to the temperature of the thermal source in Tathagata signal pipings such as the sensor be located in pipeline, electric control valve 3 and flow and flow velocity, and automatically regulates the rotating speed of water pump to come into water and moisturizing.
As preferably, described PLC 11 model is ABBAC500-eCo.
As preferably, the model of described frequency converter 13 is ACS510.
As preferably, described touch-screen 12 is 21 inches of high brightness LCD liquid crystal display, PVC facial mask touch key.
A kind of central heating control system of the utility model, the related data monitoring operating condition by PLC, realizes quantitative management, gives full play to the superiority of central heating, realize heating network operation management automation.By this control system, the past mainly relies on the control device of manual adjustment to obtain thorough improvement, and the operation of heat supply network obtains conservative control, achieves the unmanned of thermal substation.
