Description
Technical field
The utility model relates to a kind of controller of controlling rotation speed of the fan.
Background technique
Rotation speed of the fan commonly used is at present controlled by speed regulator, as required by manually-operable.Its rotating speed of existing intelligent fan is that single-chip microcomputer is installed in controller mostly, and its defective is: the integrated circuit volume is bigger, and logicality is poor, and the response time is slow, can't satisfy the requirement of user to the fan rotational stability.
CPLD (CPLD, down together) is the higher logic component of a kind of conformability, belongs to the large-scale integrated circuit (LSI) scope, is used widely in the controller field at present.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of temperature-controlled fan controller based on CPLD is provided, can adjusting rotation speed of the fan automatically with the variation of fan ambient temperature.
The technical solution adopted in the utility model is: be connected with fan electromotor by the motor gear handover module, comprise the CPLD master controller, the output of this CPLD master controller connects motor gear handover module and temperature display modular respectively, and the output of temperature acquisition parts, toggle switch controlling component, clock unit connects the input of CPLD master controller respectively; On the motor gear handover module, connect DC control supply and intelligence shelves and manual converting member.
Intelligence shelves and manual converting member comprise 5 relays, 5 inductance coils and 5 triodes, 5 tunnel control signals of being drawn by the control chip of CPLD master controller connect the ground level of triode respectively, the transmitter ground connection of triode, the collector electrode of triode is succeeded coil shelves of electrical equipment respectively, another coil shelves of relay connect the VDC of 5V, and the shelves of often opening of relay connect inductance coil respectively.
The beneficial effects of the utility model are:
1, can be installed on the normal domestic use fan, make conventional fan repack temperature-controlled fan into, comprise and installing additional, and not influence the manual control function of former fan after installing additional with ceiling fan, desk fan etc.During repacking, the circuit of controller can be integrated in the fan the inside, also can be contained in the fan outside.
2, owing to adopt based on the CPLD technology, logicality is strong, and the response time is fast, and program is not easy to run and flies.When temperature sensor senses arrives the external environment temperature variation, the signal of temperature variation can be passed to controller, after the microcontroller computing, control the speed of its running by load circuit, realize the real-time demonstration of fan ambient temperature simultaneously, temperature shows can be other display modes such as LCD (liquid crystal display, down together) demonstration or nixie tube.
3, can adjust rotating speed voluntarily according to ambient temperature, so not only allow environment keep suitable temperature, and reduced the noise that produces because of the fan high speed rotating.When the temperature rising, the speed of fan will strengthen; When the temperature reduction, the speed of fan will reduce, and it is corresponding also low that temperature is got over the slow-speed of revolution, in different temperature corresponding rotating speeds is set, and fan rotates at full speed when temperature reaches a certain temperature; Fan stops operating when temperature is lower than a certain temperature.So both improve radiating effect, reduced power consumption again, had the advantage of heat radiation, energy-conservation and noise reduction.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structure connection diagram of the present utility model.
The circuit theory diagrams that Fig. 2 selects for the fan gear.
Embodiment
As Fig. 1, the utility model is connected with fan electromotor 9 by motor gear handover module 6, and insert in the ac power supply of 220V, also connect DC control supply 8 and intelligence shelves and manual converting member 7 on motor gear handover module 6, intelligence shelves and manual converting member 7 can be selected a single-pole double-throw switch (SPDT) for use.
Core component of the present utility model is a CPLD master controller 1, the output of this CPLD master controller 1 connects motor gear handover module 6 and temperature display modular 5 respectively, the output of temperature acquisition parts 2, toggle switch controlling component 3, clock unit 4 is connected the input of CPLD master controller 1 respectively in CPLD master controller 1 periphery.Wherein, but temperature display modular 5 can be the device of other showing temperatures such as LCD or nixie tube, and temperature acquisition parts 2 can be responded to the external environment variation of temperature and the signal of CPLD master controller 1 external temperature is provided.Toggle switch controlling component 3 is used to reset, control DC electrical source and control power supply Push And Release.Clock unit 4 is used to help the proper functioning of the chip of CPLD master controller 1, can select the crystal oscillator of 50MHz for use; Temperature display modular 5 is used for showing in real time current ambient temperature.Motor gear handover module 6 realizes that the conducting of motors 9 opens, stops the function with speed change, and intelligence shelves and manual converting member 7 are used for the conversion of manual governing and temperature regulate speed, and DC control supply 8 is used for to the circuit supply of gear switch module.
As Fig. 2, intelligence shelves and manual converting member 7 are connected in the 220V power supply and blower circuit, are made up of 5 relay P1-P5, inductance coil L1-L5 and 5 NPN type triode Q1-Q5 etc.5 tunnel control signals of being drawn by the control chip of CPLD master controller 1 are connected on the ground level of triode Q1-Q5, the transmitter ground connection of triode Q1-Q5, the collector electrode of triode Q1-Q5 is received respectively on the coil shelves of relay P1-P5, the other coil shelves of relay P1-P5 connect the VDC of 5V, and the shelves of often opening of 5 relay P1-P5 are received respectively on 5 tap lines on the inductance coil L1-L5 that speed governing uses.2 of 220V Ac is followed outside one that goes between except wind-receiving fan, and another root is switched to the common port of 5 relay P1-P5.2 lead-in wires of family expenses fan, one end such as above said connecing outside the power supply, on the tap line of another termination inductance coil L1 first order (one-level of induction reactance minimum is 0), control by temperature from 5 road signals that the control chip of CPLD master controller 1 comes out, when temperature is crossed when low, output 00000, at this moment the common port of neither one relay and normal beginning are conductings, and fan is not rotated.Being provided with respectively when other temperature in 5 groups of signals corresponding with temperature has only one the tunnel to be high level, all the other are set to 00001,00010,00100,01000,10000 respectively according to different temperature, the common port of the relay that links to each other with high level and the just conducting of Chang Kai shelves are rotated fan.The inductance that is connected on the inductance coil L1-L5 in the circuit when temperature is low more is big more, what this moment, fan rotated is slow more, temperature is connected on the inductance coil L1-L5 in circuit when high more inductance is more little, and what this moment, fan rotated is fast more, when inductance little when being 0 fan rotation the fastest.
