Description
Technical field：
The present invention relates to a kind of fan control system, more particularly to a kind of SCM Based intelligent fan control system,
Belong to technical field of single chip microcomputer.
Background technology：
At present, electric fan takes cool fan as a kind of life of hot day wind, in daily life, widely should obtain
With.But traditional electric fan has following defect：First, traditional electric fan regulation wind speed relies only on manual regulation stall,
Wind speed regulation can not be carried out according to temperature.When people is in sleep state, nocturnal temperature declines, and electric fan is constantly in operation shape
State, easily make one flu of catching a cold.And the timing shutdown duration of common electric fan is in 1-2h or so, after electric fan is out of service, in temperature
Rise, can feel hot again in sleep state people, influence sleep quality.Second, traditional electric fan can not realize that people walks what is becalmed
Effect, after people leaves, fan is still working, and causes the waste of electric energy.Based on above present situation, now designing one kind can be according to temperature
Degree adjusts rotation speed of the fan and can realize that people walks the electric fan control system becalmed.
The content of the invention：
In order to make up these defects of traditional electric fan, it is contemplated that traditional electric fan is overcome the shortcomings of, in original electricity
Human body induction module and temperature detecting module of the increase using 52 series monolithics as control core on fan control system, effectively
Solve the problems, such as that traditional electric fan according to temperature adjustment rotation speed of the fan and can not be difficult to people and walk to becalm.
The technical solution adopted for the present invention to solve the technical problems is：
One kind is based on monolithic processor controlled intelligent fan control system, including pyroelectric sensor, DS18B20 TEMPs
Device, digital tube display module, Independent keys, reset circuit, crystal oscillating circuit, L298N motor drive modules.Wherein pyroelectricity senses
The input module of device, DS18B20 temperature sensors, Independent keys as single-chip microcomputer, digital tube display module, L298N motors drive
Output module of the dynamic model block as single-chip microcomputer.Pyroelectric sensor detects whether someone, and this judgement is passed into single-chip microcomputer with certainly
Determine the switch of electric fan.Ambient temperature signal is inputed to single-chip microcomputer as single-chip microcomputer input module by temperature sensor, by its with
The rule list of setting is compared in single-chip microcomputer, and the rotating speed of motor is controlled using the method for fuzzy control, and then is adjusted
The purpose of rotation speed of the fan.Meanwhile user passes through Independent keys design temperature maximum of THWith minimum value TLSet rotating speed regular with this
Table.
Brief description of the drawings：
Fig. 1 is that single-chip microcomputer controls intelligent fan control system circuit figure
Fig. 2 is the system block diagram of whole device
Embodiment：
The explanation of embodiment is carried out with reference to Figure of description：It is SCM Based intelligent fan control in Fig. 1
System circuit diagram.The wherein input module of pyroelectric sensor, DS18B20 temperature sensors, Independent keys as single-chip microcomputer, number
Code pipe display module, output module of the L298N motor drive modules as single-chip microcomputer.
First, for user after fan power supply is opened, the pyroelectric sensor being connected with single-chip microcomputer P1.4 mouths starts collection letter
Number, someone is detected, this signal is sent to single-chip microcomputer processing, single-chip microcomputer starts intelligent fan control system.User by S1,
These three Independent keys of S2, S3 carry out design temperature threshold value, and are shown simultaneously in charactron.S3 is pressed first, is shown as temperature
Maximum, temperature value is now reduced by S1, the size of S2 temperature-adjustable maximums, S1 increase temperature values, S2.Press again
S3, temperature-adjustable minimum value.The two numerical value combination SCM system inner setting rule lists can generate a specific speed of rotation
Rule list, the indoor temperature gathered by the temperature sensor being connected with single-chip microcomputer P1.3 mouths is compared, corresponding to choose
At a temperature of corresponding rotating speed.When the temperature of temperature sensor collection is less than the minimum temperature value set, system can change electricity
Machine drive signal, makes stopping fan rotation；When right temperature exceedes setting maximum, fan can full-speed operation.Once user leaves
During pyroelectric sensor effective monitoring scope, it is not necessary to which user's deenergization, single-chip microcomputer will input according to pyroelectric sensor to be believed
Number, change motor drive module signal, stopping fan rotation.
PWM ripples can not be produced inside 52 single-chip microcomputers, are changed by changing timer timing length in interrupt routine to height
It is low level cumulative, then change dutycycle, so as to reaching the mesh of control rotating speed.
Reset key S is used for processing unit bursting problem in Fig. 1, presses reset key, system re-initialization, temperature threshold
Value can all return to system initial state, and fan can also stop operating.
Fig. 2 is the system block diagram of whole device, and the device includes pyroelectric sensor, DS18B20 temperature as can be seen from Figure
Spend sensor, digital tube display module, Independent keys, reset circuit, crystal oscillating circuit, L298N motor drive modules.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, it all should fall into the protection domain of claims of the present invention determination.
