Description
Technical field
This utility model relates to a kind of electric-control system, is specifically related to heat exchange station electric-control system, belongs to heat exchange station communication technique field.
Background technology
The most perfect along with heat exchange station heating system, the function of electric-control system is the most increasingly paid close attention to by people and approves, more comes
The most instrumentations need to be incorporated in the control of electric-control system.Intelligent control box (cabinet) is the weight of heat exchange station electric-control system
Want ingredient, and touch screen (HMI) and programmable logic controller (PLC) (PLC) are the compositions of intelligent control box (cabinet)
Core.Instrument all in heat exchange station, data are gathered and computing by traditional communication modes often by PLC, and recycling is touched
Touching the communication between screen (HMI) and PLC and set up the display realizing overall data, this means that once PLC goes wrong
Or communication is broken down between PLC and touch screen (HMI), all of data will be unable to showing accurately and timely,
Cause the very big puzzlement that heat exchange station digital independent or even equipment state judge, and this kind of communication modes simply achieves touch screen
(HMI) communication modes of the corresponding a kind of agreement of single serial ports.
Utility model content
The purpose of this utility model is to have that communication modes is single, data to solve heat exchange station electric-control system of the prior art
The problem that communication robust is poor, data exchange rate is low.
The technical solution of the utility model is: heat exchange station electric-control system, including remote control unit, sets of temperature sensors, pressure
Power transmitter group, refill flow meter, high water tank meter, electric control valve, electromagnetic relief valve and frequency conversion tank, described long-range control
Unit processed includes PLC and touch screen, touch screen includes DB9 interface, described DB9 Interface integration RS485
Physical connection mouth and RS232 physical connection mouth, described electric control valve, electromagnetic relief valve and frequency conversion tank, temperature sensor
Group, pressure transmitter group, refill flow meter and high water tank meter all gather data and control, PLC by PLC
Controller is set up two-way communication by RS232 physical connection mouth with touch screen and is connected, and described calorimeter passes through RS485 physics
Connector connects touch screen.Described sets of temperature sensors include a net supply water temperature sensor, a net return water temperature sensor,
Two net supply water temperature sensors and two net return water temperature sensors.
Described pressure transmitter group includes that a net pressure of supply water transmitter, a net pressure of return water transmitter, two net pressure of supply waters become
Send device and two net pressure of return water transmitters.
Described frequency conversion tank includes circulating pump converter and small pump converter.
Described heat exchange station electric-control system includes heat-exchangers of the plate type, water circulating pump, small pump and hotlist, described board-like heat exchange
Device, water circulating pump and small pump are all connected with PLC, and described hotlist passes through RS485 physical connection mouth and touch screen
Set up and connect.
This utility model compared with prior art has the effect that in heat exchange station of the present utility model that the data of instrument can be
PLC, touch screen (HMI) gather simultaneously, have both reduced the communication burden of PLC, have strengthened again touch
The use function of screen (HMI), greatly reduces the communication failure relative risk of electric-control system；Heat exchange station instrument is by different
This kind of communication modes can be used between connector and PLC and special touch screen (HMI)；The most both ensure that
Communication robust between PLC and part instrument and touch screen (HMI), improve data exchange rate, also by a part of instrument
Table establishes efficient communication with touch screen (HMI) and is connected, and effectively avoids PLC and Communication or PLC occurs and touch
Touch and the inconvenience that communication failure brings occurs between screen (HMI), optimize equipment composition, reduce while cost puts into as producing
Producer and user bring higher economic benefit and social benefit.
