Brief description of the drawings
Fig. 1 is intelligent fan structural representation of the utility model based on PWM.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
A kind of intelligent fan based on PWM, as shown in Figure 1：It includes AVR single chip, temperature sensing module, storage mould
Block, numeral method module, PWM control modules, power module, input through keyboard module, motor, the AVR single chip respectively with
Temperature sensor, memory module, numeral method module, PWM control modules, power module be connected, the PWM control modules with
Motor is connected, and motor is provided with fan blade；The memory module is connected with input through keyboard module；The temperature sensor and ice
Brilliant box control module is connected, when temperature does not drop to design temperature, and ice crystal box control module is started by temperature sensor, when
When temperature drops to design temperature, ice crystal box control module is closed by temperature sensor, so as to reach more preferable cooling-down effect.
The temperature sensing module is DS18B20 temperature sensing modules, and the temperature sensor small volume hardware circuit is simple,
Belong to the modified intelligent temperature sensor of a new generation's adaptation microprocessor.DS18B20 digital thermometer provides 9 to 12
Celsius temperature is measured, and with user-programmable upper and lower bound warning function.The application of this characteristic include HVAC,
Temperature detection and process monitoring and control system in environmental Kuznets Curves, building, equipment or machinery.
The input through keyboard module is provided with Chose selection keies, Reset system reset keys, "+" temperature plus key, "-" temperature
Subtract key.
Start：Turn on the power rear intelligent fan to bring into operation, now fan numeral method Current Temperatures.
Operating temperature is set：Press temperature after Chose keys and show that charactron 10 starts flicker, 10 temperature can be now set
Degree, presses "+" heating degree, presses "-" desuperheat degree.Chose keys are pressed after the completion of 10 temperature of setting, now temperature display is digital
Pipe position starts flicker, presses "+" heating degree, presses "-" desuperheat degree.A Chose key is pressed after being provided with again, it is now digital
Pipe is no longer flashed, and fan work range temperature is provided with, and now charactron will show Current Temperatures, and design temperature is then saved
To memory module.
Speed governing：System starts to monitor environment temperature after the completion of temperature setting.
When environment temperature is less than design temperature, motor does not start.
When environment temperature is more than design temperature, motor starts to start, and is started working with minimum speed.
When environment often more than 1 degree Celsius when, motor accelerates one grade automatically.
When environment temperature exceedes 4 degrees Celsius of design temperature, motor is worked with maximum (top) speed speed.
The temperature of user's setting will be conserved, even if after power-off, next time sends a telegram here.System will continue the last time
Temperature is set.Reach the requirement of intelligent fan.
The utility model is the intelligent fan controlled based on AVR single chip, mainly using single-chip microcomputer as core, is added
DS18B20 temperature sensors carry out the detection to system local environment temperature, so that whether intelligent decision needs to open fan, and
According to the difference of temperature come the different rotating speed of regulation motor, using PWM speed regulating control direct current generators, can allow electric fan realize from
0 arrives the interval speed governing of maximum (top) speed.Traditional electric fan gear wind speed is solved with this and changes discomfort that is excessive and causing.In addition,
Whether it also has the advantages that intelligent switch, by setting range temperature, realize intelligent fan detection indoor temperature in setting temperature
Judge whether to open fan within the scope of degree.This can effectively solve the problem that temperature not in setting range and fan still work institute
The power supply caused is wasted.Meanwhile, intelligent fan can realize the electricity when temperature is higher than user's design temperature plus temperature sensor
Fan is opened, and fan does not work when temperature is less than design temperature.In addition can also according to the change of temperature intelligent speed-regulating, make environment
Temperature control is in a most comfortable temperature range.Numeral method real time temperature, allows user to have a more good experience.
The major control feature and performance requirement of the design are as follows：Intelligent switch function is realized, fan can detect indoor temperature, system
The temperature range set according to user judges whether fan is opened, if more than the minimum temperature of setting, fan is started working；It is real
Existing intelligent temperature control function, fan can be with automatic detection environment temperature, and the temperature range that system is set according to user is so as to adjust wind
Rotating speed is fanned, in design temperature, environment temperature often rises 1 degree Celsius, then fan adds one grade of wind speed automatically, when environment temperature exceedes
During 4 degrees Celsius of design temperature, rotation speed of the fan reaches maximum.Otherwise when environment temperature drops to below design temperature maximum
When, often decline once, one grade of work drops in rotation speed of the fan automatically, when environment temperature is dropped to below design temperature, then fan stops
Work, intelligent temperature control function is reached with this；Realize stepless time adjustment function：Using PWM speed governing, it may be achieved rotation speed of the fan is from 0 to most
High-power speed-adjusting.Fan is set to reach linear change in velocity variations；Realize that real time temperature is shown：System is used as using charactron
Temperature display can show Current Temperatures, realize more preferable Consumer's Experience.
