And current heating systems adopts local control usually; The heat supply unit is regulated electric control valve and the variable frequency pump in the secondary pipe network in the pipe network one time according to the running status of heating network; User terminal adopts independent behaviour's table system to carry out the heat monitoring, and behaviour table system and heating system are separate, and intelligent degree is lower; And heating system do not consider the actual conditions of user terminal in control procedure, and heating efficiency is not high.

The utility model content

To the deficiency of prior art, the purpose of the utility model provides a kind of intelligent heating and controls system, improves the intelligent degree and the heating efficiency of system.

To achieve these goals, the scheme that the utility model adopted is:

A kind of intelligent heating is controlled system; Comprise heating system and kilowatt meter reading-out system; Said heating system is provided with electric control valve, variable frequency pump, small pump, superpressure drain valve and heat supply measuring instrument; Said kilowatt meter reading-out system is connected with the calorimeter of each user terminal; Its key is: said heating system links to each other with remote control center through GPRS or Internet network with kilowatt meter reading-out system, and remote control center receives the data of heat supply measuring instrument and calorimeter and controls electric control valve, variable frequency pump, small pump and the work of superpressure drain valve.

Can each calorimeter institute data monitored of real time inspection user terminal at remote control center, and according to user's actual consumption heat and advance information such as return water temperature and come heating system is controlled, thereby reach pipe network heat supply balance and energy-saving effect.

As further describing, said heat supply measuring instrument comprises a pipe network heat supply calorimeter, a pipe network water supply water pressure gauge, a pipe network water supply thermometer, pipe network backwater water pressure gauge, secondary pipe network supply water temperature table, secondary pipe network heat supply calorimeter and a secondary pipe network differential pressure detection table.

The operational factor that in remote control center, can also show heating system in real time comprises that a pipe network heat supply heat, a pipe network water supply hydraulic pressure, a pipe network water supply temperature, pipe network backwater hydraulic pressure, secondary pipe network supply water temperature, secondary pipe network heat supply heat and a secondary pipe network supply backwater pressure reduction etc.

The remarkable result of the utility model is: the intelligent degree that improves system; Realize Long-distance Control, and in the control procedure of heating system, considered the actual conditions of user terminal; Control according to user terminal calorimeter institute data monitored, improved the thermal efficiency.
