Accompanying drawing explanation
Fig. 1 is utility model works schematic diagram.
Fig. 2 is RS485 bus communication circuitry figure described in the utility model.
Embodiment
The utility model provides a kind of air source heat pump control 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 net for air-source heat pump units running environment, running current is large, electromagnetic interference (EMI) 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 module 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 module with 32 single-chip microcomputer STM32F103VB processors for core, and be made up of simulating signal (temperature and pressure) acquisition module, On-off signal/output module and communication module, the simulating signal of each component sensors of timing acquiring net for air-source heat pump units and switching value numerical value.Simulating 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 layout 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 message exchange.On the one hand, man-machine interaction unit receives data acquisition and control module turns over next data and shows, and the operations such as process and storage, detect the operation conditions of net for air-source heat pump units, judge whether each member pressure of unit and temperature value operation etc. are normal.When unit occurs abnormal, control system can carry out breakdown judge immediately, determines fault occurring source, and sends alerting signal, and unit discharges fault by the time.Meanwhile, user also can carry out man-machine interaction by touch-screen and air 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 module at long last by RS485 data, resolution data frame, performs the output of switching value, realize the control to net for air-source heat pump units according to command content.
