Abstract
The utility model discloses an electric fan controller, which comprises a power supply module, a sensor module, a single-chip microcomputer and a driving circuit, wherein the single-chip microcomputer is respectively connected with the power supply module, the sensor module and the driving circuit; the single-chip microcomputer receives a signal collected by the sensor module and sends a control signal generated by the signal to the driving circuit; and the driving circuit receives the control signal sent from the single-chip microcomputer to control the electric fan to be started and stopped. The electric fan controller disclosed by the utility model has the advantages of energy saving and environment protection because the electric fan is controlled to be started and stopped according to the environment temperature.
Description
Technical field
The utility model belongs to automation field, particularly relates to a kind of Electric fan controller.
Background technique
In summer, people will use electric fan conventionally, but there is sometimes people, have left to settle and forget the situation of closing electric fan, cause unnecessary waste, so need a kind ofly can automatically identify the Electric fan controller that has nobody.Related product in the market is mostly only conceived to machinery and controls, and without the function of automatically controlling, and cannot according to ambient temperature, control the keying of electric fan, can not play the effect of economize on electricity environmental protection.
Model utility content
According to the deficiency of above-mentioned background technology, the utility model aims to provide a kind of Electric fan controller.
In order to reach above-mentioned purpose, the technical solution of the utility model is:
A kind of Electric fan controller, comprise supply module, sensor assembly, single-chip microcomputer and drive circuit, described single-chip microcomputer is connected with aforesaid supply module, sensor assembly and drive circuit respectively, described single-chip microcomputer receives the signal of aforesaid sensor assembly collection and sends the control signal that signal produces thus to aforesaid drive circuit, and the control signal that drive circuit reception single-chip microcomputer sends is controlled the keying of electric fan.
Wherein, above-mentioned supply module comprises power supply, electric pressure converter and hand switch, and described power supply is connected and powers with aforesaid single-chip microcomputer with hand switch through electric pressure converter.
Wherein, above-mentioned sensor assembly comprises infrared senor and temperature transducer, and the infrared senor of stating is connected with single-chip microcomputer respectively and sends the signal collecting separately to single-chip microcomputer with temperature transducer.
Wherein, above-mentioned drive circuit comprises amplification circuit and relay, described amplification circuit receives the control signal that single-chip microcomputer transmits, and to the winding of relay will be sent after this control signal amplification, the contact of described relay is connected with electric fan, and described relay is controlled the break-make of contact according to control signal.
The technique effect that adopts technique scheme to reach has: adopt single-chip microcomputer as control circuit, precise control, makes circuit simple, can carry out function upgrading by connecting computer; Circuit structure is simple, and reliability is very high; Adopt temperature transducer and infrared senor co-controlling, can also be according to there being nobody automatically to control start and stop when can control electric fan start and stop according to ambient temperature.
Accompanying drawing explanation
Fig. 1 is system block diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated.
A kind of Electric fan controller as shown in Figure 1, comprises supply module, sensor assembly, single-chip microcomputer and drive circuit.Single-chip microcomputer is connected with supply module, sensor assembly and drive circuit respectively, and the signal of single-chip microcomputer receiving sensor module collection also sends the control signal that signal produces thus to aforesaid drive circuit.The control signal that drive circuit reception single-chip microcomputer sends is controlled the keying of electric fan.In the present embodiment, described supply module comprises power supply, electric pressure converter and hand switch, power supply is connected with aforesaid single-chip microcomputer with hand switch through electric pressure converter successively and to single-chip microcomputer power supply, 220 volts of power frequency ac voltages that electric pressure converter sends power supply are converted into 5 volts of required VDC of single-chip microcomputer.Described sensor assembly comprises infrared senor and temperature transducer, and infrared senor is connected with single-chip microcomputer respectively and sends the signal collecting separately to single-chip microcomputer with temperature transducer.Described drive circuit comprises amplification circuit and relay, and amplification circuit receives the control signal that single-chip microcomputer transmits, and after this control signal is amplified, sends the winding of relay to, and the contact of relay is connected with electric fan.
When user presses after hand switch, supply module is powered to single-chip microcomputer, after single-chip microcomputer initialization, enters holding state.When infrared senor receives after human infrared signal, send signal to single-chip microcomputer, simultaneous temperature sensor also sends the ambient temperature signal collecting to single-chip microcomputer, single-chip microcomputer compares the ambient temperature signal receiving and setting value, if ambient temperature is higher than setting value, single-chip microcomputer sends the control signal of opening electric fan to amplification circuit, and amplification circuit amplifies control signal the contact adhesive of rear driving relay, starts to start after fan circuit closure; If temperature is lower than setting value, system is returned, and continues collection signal.
In electric fan working procedure, infrared senor does not collect suddenly human infrared signal, and single-chip microcomputer sends the control signal of cutting out electric fan to amplification circuit, and amplification circuit amplifies rear driving relay contact by control signal and disconnects, and closes electric fan.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technological scheme basis, within all falling into the utility model protection domain.
