The specific embodiment:
By reference to the accompanying drawings and the specific embodiment, the present invention is further described.
Embodiment
According to the feature of solar water heater and the requirement to control system, the invention provides a kind of SCM Based solar water heater intelligence control system, native system comprises system hardware and two parts of software program.As shown in Figure 1, a kind of SCM Based solar water heater intelligence control system, comprise single-chip microcomputer, each separate module being connected with single-chip microcomputer, each described separate module comprises: for detection of the water storage box temperature detecting module of water temperature in storage tank, for detection of the water level detecting module of water level in storage tank, for showing the LCD LCD MODULE of water temperature information and water level information, for the alarm module of water level overload alarm, for the clock module of timing, for setting the keyboard input module of timing time and water temperature and being used to the power module of system power supply.
In the present embodiment, described water storage box temperature detecting module adopts temperature sensor DS18B20, described LCD LCD MODULE is LCD1602 display module, and described water level detecting module is segmentation liquid level sensor, and described clock module adopts clock chip DS1302.
Water temperature in DS18B20 Real-Time Monitoring storage tank, and the water temperature information exchange monitoring is crossed to LCD1602 module show; Segmentation liquid level sensor Real-Time Monitoring water level information, if water level transfinites, starts and reports to the police; System is set preheating time by keyboard input module, and clock chip DS1302 plays clocking capability, thereby user can be according to the demand Preset Time of oneself and temperature maintenance water temperature regularly.
The design of temperature detecting module circuit be the unique digital data transmission port of digital temperature sensor DS18B20 is connected with the P3.7 of single-chip microcomputer and by the temperature signal of induction real-time pass to single-chip microcomputer.Pull-up resistor R3 is that the resistance of generally selecting can be larger in order to allow DS18B20 keep a stable working environment when being connected to working power.Meanwhile, pull-up resistor can also allow DQ in idle, keep high level.
Digital temperature sensor DS18B20 can be real-time water temperature is transmitted to single-chip microcomputer, and show by display screen, allow user be well understood to Temperature Regime of Main now.In addition, the control (opening or close auxiliary heating system) that the temperature signal that single-chip microcomputer comes according to transmission carries out system again regulates and controls water temperature.
The operating key of keyboard input module is unique interface of user intervention system operation, is also the problem that user is relatively concerned about.In order to realize control system to the setting of time and temperature and Presentation Function, designed key interrupting input.Because this system function fairly simple comparatively speaking, with matrix keyboard, relatively waste, and more there is no need with keyboard drive chip, although can liberate the work cost of single-chip microcomputer higher with hardware circuit design more complicated.So finally only used simple stand-alone keypad.
LCD1602 display module circuit diagram connection line is: data port is the P2 mouth of single chip computer AT 89S52, and P2 mouth is connected with the D0-D7 mouth of LCD, and the P3.0 mouth of single-chip microcomputer is connected with the RS mouth of LCD, and P3.1 is connected with the E mouth of LCD.VSS and VDD are respectively the earth terminal of chip and connect power end, and VEE can not connect.When RS is high level, be data-signal, when it is command signal during for low level.When RW is high level, be data read mode, when it is that data are write delivery formula during for low level.E is enable signal end.So-called enable signal end refers to an input port of control chip work, and while only having this pin to be activated, chip could be worked.Generally E is that high level is effective.
