Each sensor transmits the collected temperature signals to the controller in real time, the signals are compared with a set optimum signal through the controller, an executing mechanism is driven to control the water supply flow, and the on-demand heating and energy saving of the heating system can be realized.
Description
Affiliated technical field:
The disclosed heating system supply water temperature of the utility model automatic control system belongs to the central heating system field of energy-saving technology, and what be specifically related to is a kind of utility model device that can control the supply water temperature situation automatically.
Background technology:
In the existing central heating system, especially sub-district central heating system, major part is to remove to regulate and control to supply with user's supply water temperature by artificial experience according to oneself, the temperature height just adjust the large and small fire of boiler or the primary side valve of heat exchange station, so need Attended mode, and because in heating season, altering a great deal of outdoor temperature, spend subzero twenty or thirty degree from above freezing tens, day and night temperature often also can surpass 10 degree in one day, because the artificial adjusting of carrying out on duty is a discontinuity, blanking time is long, often cause user indoor temperature higher easily, cause with wasting, public character building particularly is as office building, factory building, teaching building etc., because the characteristic of its purposes, normally heat supply of working time then can cold operation in festivals or holidays and night, and owing to be inconvenient to control, actual is to need the user of heat supply the same as continuous heat supply with other 24 hours, also causes energy waste." heating system supply water temperature automatic control system " of the present utility model can provide a kind of cost low, the supply water temperature automaton of realizing automation control easy for installation.
Summary of the invention:
The purpose of the present utility model is: recommend this heating system supply water temperature automatic control system to central heating system unit, for rationally with heat, do a little work with hot, energy savings as required.
The utility model is realized with following technical scheme: a kind of heating system supply water temperature automatic control system, it is characterized in that: it comprises Programmable Logic Controller, gather real-time supply water temperature, gather real-time return water temperature, gather real-time outdoor temperature, gather real-time indoor temperature, above-mentioned each sensor is electrically connected with the input of control able to programme respectively, and the signal of gathering is flowed to Programmable Logic Controller; It also comprises the electric control valve and the fault alarm of the control discharge that is electrically connected with the I/O interface of Programmable Logic Controller.
Its operation principle is: every temperature signal parameter input controller that each sensor will be gathered, compare by the parameter and the predefined optimum working parameter of controller input, control the aperture of electric control valve then, outwards supply water or heat exchange station primary side water supply flow with continuous adjusting boiler, make the supply water temperature in the secondary heating system reach range of set temperature, heat supply rationally reduces because of what variations in temperature caused and uses heat waster.
The utility model has the advantages that: systemic-function is complete, can finish whole signals collecting, control drives automatically, energy savings, and the mean free error time is more than 10 years.

The specific embodiment:
As shown in Figure 1, the sensor that native system is gathered each temperature signal comprises: outdoor temperature sensor (1) adopts PT100, is output as 4～20mA signal of telecommunication, gathers outdoor temperature in real time; Indoor temperature transmitter (2) adopts PT100, is output as 4～20mA signal of telecommunication, gathers outdoor temperature in real time; Supply water temperature sensor (3) adopts PT100, is output as 4～20mA signal of telecommunication, in real time supply water temperature in the acquiring heat supply system; Return water temperature sensor (4) adopts PT100, is output as 4～20mA signal of telecommunication, in real time return water temperature in the acquiring heat supply system; Programmable Logic Controller (6) adopts industrial Programmable Logic Controller Siemens S7-200PLC.Above-mentioned each sensor all is electrically connected with the input port of Programmable Logic Controller (6) to Programmable Logic Controller (6) and carries all temps information of gathering.The I/O interface of Programmable Logic Controller is electrically connected with the electric control valve (7) that the alarm of reporting to the police when fault is arranged (8) was electrically connected and controlled to adjust water supply flow, and it is 0～10V or 4～20mA signal of telecommunication that electric control valve (7) adopts input and output.In controller, store working procedure as shown in Figure 2.
Fig. 3, shown in Figure 4, display frame and parameter when system's operation is arranged on the touch-screen (5) are provided with picture.
Its control principle is: the real-Time Signal Transfer that each sensor will be gathered is in real time given Programmable Logic Controller, and the data of Programmable Logic Controller and setting relatively drive electric control valve control water supply flow in optimum state with result.
Its energy-saving principle is:
(1) can realize heating according to need
Heating system is by control automatically, making the thermal source of confessing is that supply water temperature can be according to the variation of outdoor temperature, carry out analysis-by-synthesis and optimizing adjustment, formation changes supply water temperature with outdoor temperature and also changes synchronously, to reach the effect of the unapproachable approximate ideal of manually-operated, allow unwanted thermal source not participate in circulating and getting back in the boiler.Simultaneously can also carry out the refinement adjustment to the requirement difference of supply water temperature, reach the purpose of heating according to need according to the different periods in one day.
(2) realize dividing time-division temperature heat supply to public building
Heating system is by control automatically, can control each public building building separately, can carry out independent heat supply according to different time sections, can realize normal heat supply of working time, night and festivals or holidays nobody the time realize the antifreeze function of cold operation, promptly allow the constant level in this building at a low temperature heating, allow be fed to water supply flow fair supply in this building, to reach the unapproachable control effect of manually-operated, reach the purpose of heating according to need.
