Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
See Fig. 1, a kind of intelligent temperature control speed-regulating fan, system architecture comprises SCM system, digital temperature sensor module, temperature display module, motor control module and input through keyboard module, the output terminal of described digital temperature sensor module is connected with the input end of described SCM system, the input end of described temperature display module is connected with the output terminal of described SCM system, the input end of described motor control module is connected with the output terminal of described SCM system, and the output terminal of described input through keyboard module is connected with the output terminal of described SCM system.Described SCM system adopts STC89C52 single-chip microcomputer, and described digital temperature sensor module adopts DS18B20 digital temperature sensor, and described motor control module adopts zero passage two-way type controllable silicon optocoupler.
Fig. 2 gives digital temperature sensor module circuit diagram of the present utility model.Digital temperature sensor module adopts DS18B20 digital temperature sensor, adopts single line technology when Signal transmissions, only uses the signaling line of a transmitted in both directions, can transmission clock signal, can also transmit corresponding data information.Use the main frame of this technology can realize controlling the function of one or more slave simultaneously, specific works mode is by connecting opening Lou or tri-state port of described datawire, thus reach when a slave does not send signal, allow other equipment by data line transfer signal.The temperature signal sensed is become digital signal by DS18B20 digital temperature sensor after suitably processing, and sends master controller to by transfer wire.
Fig. 3 gives motor control module internal circuit diagram of the present utility model.Motor control module adopts zero passage two-way type controllable silicon optocoupler, triggers when the major function had comprises light harvesting electric isolution, automatically detection zero passage and crosses nought state.Adopt this optocoupler to efficiently avoid signal in traditional galvanic couple to control silicon controlled at input output channel simultaneously, make the Signal transmissions of system more efficiently convenient, thus make the structure of circuit output channel more reliable.R represents motor load, when system user design well corresponding parameter information time, single-chip microcomputer will make some responses to this information, just high level signal is sent to I/O port afterwards, again by phase inverter process after its reverse, convert low level signal to and export, photo coupler is switched under the control of the controller, meanwhile bidirectional triode thyristor is also switched on, and then whole circuit is just energized work.
Fig. 4 gives workflow diagram of the present utility model.After the main program of initialization system, need repeatedly the correlated identities in the buffer area of four modules of checking system, after the buffer area set of module, the related data of its inside also needs process, and this process need primary processor is coordinated the cooperation of each puocessing module and jointly completed.Form temperature by temperature sensor module and temperature display module and control submodule, realize temperature transition to become digital signal, and then the change of analysis temperature.Keyboard control submodule is triggered by bidirectional triode thyristor, and bidirectional triode thyristor conducting is by 52 Single-chip Controlling with closing.The adjustment of bearing power is mainly through realizing to change through silicon controlled signal wave number, and signal wave number, mainly by silicon controlled switch control rule, by above step, can realize the adjustment to rotation speed of the fan.
