A kind of centralized control system of district heating

Technical field

The present invention relates to heat supply process field, the centralized control system of specifically a kind of district heating.

Background technology

Along with the development of urbanization and heat supply compartmentalization, downtown areas heat supply is more and more general, but current regional heat supply great majority all also exist the problems such as energy consumption is high, dispersion is unfavorable for centralized management, accident risk is large, and each heat exchange station adopts the management mode of independent operating mostly, lack comprehensively, operating analysis exactly, cause district heating can not dispatch in time according to actual demand, cause thermal misadjustment, affect heating effect.

Summary of the invention

The object of the present invention is to provide the centralized control system of a kind of convenient management, safe, economic district heating.

The technical solution adopted for the present invention to solve the technical problems is: a kind of centralized control system of district heating is primarily of district heating monitoring station, communication network and several heating plant unit composition, each heating plant unit comprises heat exchange station switch board and heat supply user, and in heat exchange station switch board, be provided with cell controller and GPRS monitoring module, in heat supply user, packing has user's temperature to control acquisition module, user's temperature controls acquisition module and is used for Real-time Collection heat supply user temperature signal, and the temperature signal collected is transferred to district heating monitoring station by communication network, described communication network is GPRS network.

Cell controller in described each heating plant unit also controls acquisition module connecting communication with GPRS monitoring module and user's temperature respectively.

Described cell controller automatically controls and heating according to need each self-corresponding heating plant unit, and the temperature signal detected or regulate and control, pressure signal, flow signal, water level signal, valve opening and switching signal, water pump operation and stop signal, frequency converter frequency signal, electrical contact signal are sent to district heating monitoring station by GPRS monitoring module and communication network.

Operation principle of the present invention is, each heating plant unit realizes automatically controlling and heat supply by the cell controller in heat exchange station switch board, simultaneously, user's temperature controls the temperature signal of acquisition module Real-time Collection heat supply user, the temperature signal that each signal that GPRS monitoring module is then sent by communication network by district heating monitoring station and user's temperature control acquisition module Real-time Collection is analyzed, calculate, process, statistics, store display and early warning and alarming, and according to its analysis and treament result, in real time adjustment signal is exported by communication network again to each heating plant unit, each heating plant unit is made to be in the centralized management pattern of district heating monitoring station monitoring, reach unified monitoring, monitoring and heating according to need full-automatic, efficiently, energy-conservation, reasonable and safe effect.

The invention has the beneficial effects as follows, the present invention has effect of centralized management and unified regulation and control, and system configuration is simple, and security of operation is efficient, and its result of use is good, and cost is low.

Detailed description of the invention

Be described in detail below with regard to the centralized control system of accompanying drawing 1 to a kind of district heating of the present invention below.

As shown in Figure 1, the centralized control system of a kind of district heating of the present invention is primarily of district heating monitoring station 1, communication network 2 and several heating plant unit 3 form, each heating plant unit 3 comprises heat exchange station switch board 4 and heat supply user 7, and in heat exchange station switch board 4, be provided with cell controller 5 and GPRS monitoring module 6, in heat supply user 7, packing has user's temperature to control acquisition module 8, user's temperature controls the temperature signal of acquisition module 8 for Real-time Collection heat supply user 7, and the temperature signal collected is transferred to district heating monitoring station 1 by communication network 2, described communication network 2 is GPRS network.

Cell controller 5 in described each heating plant unit 3 also controls acquisition module 8 connecting communication with GPRS monitoring module 6 and user's temperature respectively.

Described cell controller 5 automatically controls and heating according to need each self-corresponding heating plant unit 3, and the temperature signal detected or regulate and control, pressure signal, flow signal, water level signal, valve opening and switching signal, water pump operation and stop signal, frequency converter frequency signal, electrical contact signal are sent to district heating monitoring station 1 by GPRS monitoring module 6 and communication network 2.

Operation principle of the present invention is, each heating plant unit 3 realizes automatically controlling and heat supply by the cell controller 5 in heat exchange station switch board 4, simultaneously, user's temperature controls the temperature signal of acquisition module 8 Real-time Collection heat supply user 7, the temperature signal that each signal that GPRS monitoring module 6 is sent by communication network 2 by district heating monitoring station 1 and user's temperature control acquisition module 8 Real-time Collection is analyzed, calculate, process, statistics, store display and early warning and alarming, and according to its analysis and treament result, in real time adjustment signal is exported by communication network 2 again to each heating plant unit 3, each heating plant unit 3 is made to be in the centralized management pattern of district heating monitoring station 1 monitoring, reach unified monitoring, monitoring and heating according to need full-automatic, efficiently, energy-conservation, reasonable and safe effect.

1. the centralized control system of a district heating forms primarily of district heating monitoring station, communication network and several heating plant unit, it is characterized in that, each heating plant unit comprises heat exchange station switch board and heat supply user, and in heat exchange station switch board, be provided with cell controller and GPRS monitoring module, in heat supply user, packing has user's temperature to control acquisition module, and the cell controller in each heating plant unit also controls acquisition module connecting communication with GPRS monitoring module and user's temperature respectively.
