Detailed description of the invention
The utility model provides a kind of ground source heat pump control system based on embedded system, for making the purpose of this utility model, technical scheme and effect better clear, clear and definite, further describes the utility model referring to accompanying drawing.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and need not with restriction the utility model.
Relatively severe for earth source heat pump unit operation environment, running current is large, electromagnetic interference is serious and controller self-operating time produce the problem disturbed, the utility model is divided into graphical touch control unit and data acquisition and control unit control system.Two unit work alone, and by RS485 bus communication between unit, not only antijamming capability is strong, system is more stable, and control system highly versatile, is convenient to expansion and the replacement of control system.
As shown in Figure 1, data acquisition of the present utility model and control unit with 32 single-chip microcomputer STM32F103VB processors for core, and be made up of analog signal (temperature and pressure) acquisition module, On-off signal/output module and communication module, the analog signal of each component sensors of timing acquiring earth source heat pump unit and switching value numerical value.Analog signal enters AD conversion and formulae discovery in sheet through analog signal processing and obtains required numerical value, and the data after conversion are sent to graphical touch control unit with certain data format by RS485 bus and process further.Graphical touch-control Duan Yuan is with 32 single-chip microcomputer S3C2410 processors for core, and the peripheral interfaces such as fluid,matching crystal display screen, touch-screen, USB port, Ethernet interface and module carry out the function of finishing man-machine interaction and information exchange.On the one hand, man-machine interaction unit receives data acquisition and control unit and turns over the data come and also show, the operations such as process and storage, the operation conditions of detection earth source heat pump unit, judge each member pressure of unit and temperature value, the operation of pressure garlic machine etc. whether normal.When unit occurs abnormal, control system can carry out breakdown judge immediately, determines fault occurring source, and sends alarm signal, and unit discharges fault by the time.Meanwhile, user also can carry out man-machine interaction by touch-screen and ground source heat pump control system, arranges the parameter of system, inquiry operating states of the units, historical failure record.The system operational parameters that user is arranged, transfers to data acquisition and control unit at long last by RS485 data, resolution data frame, performs the output of switching value, realize the control of source source pump over the ground according to command content.
