Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only some embodiments of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The fan installed in a device is as heat radiation instrument, along with the change of applicable cases Yu ambient temperature, it may be desirable to different rotating speeds fan meets demand. Although prior art exists the fan of some adjustable fan rotating speeds, but it is often based on heat gain from appliance and equipment size or equipment cooling efficiency, when ambient temperature or equipment self operating temperature are higher, adopting runs up meets the radiating requirements of equipment, and fan is fixed on a high rotating speed of comparison, although being on higher radiating efficiency, but often noise increases, and easily causes the initial failure of fan.
In order to realize the accurate control to rotation speed of the fan, the embodiment of the present invention proposes the technical scheme that a kind of rotation speed of the fan controls.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Fig. 1 illustrates the schematic flow sheet of the fan rotational frequency control method that the embodiment of the present invention provides, and this flow process can be applicable to be provided with the equipment of fan, by being implemented in combination in of software or software and hardware, as it is shown on figure 3, this flow process comprises the steps:
Step 101: obtaining the parameter for determining fan target rotating speed, described parameter includes one or more of: the ambient parameter of equipment place environment, equipment lay the operating power of attitude parameter and equipment.
Wherein, the ambient parameter value of equipment place environment, it is possible to include one or more of: ambient temperature value, ambient pressure value and environmental wet angle value. Further, it is also possible to include such as the parameter with equipment place environmental correclation of ambient wind velocity etc. some other.
Owing to equipment cooling is exactly self heat be discharged in the environment at equipment place, the ambient temperature of equipment place environment will affect the heat radiation of equipment, wherein, ambient temperature can include the ambient temperature of equipment place environment, it is also possible to includes the interior environment temperature of equipment place environment. In different ambient temperature value situations, to the demand of rotation speed of the fan also difference to some extent, therefore the ambient temperature value of equipment place environment could be for one of ambient parameter determining fan target rotating speed. Specifically, for the acquisition of the ambient temperature value of equipment place environment, it is possible to be obtained by temperature sensor measurement. Wherein it is preferred to, temperature sensor can be arranged on the air inlet of equipment. In some specific embodiments of the present invention, temperature sensor can be NTC (NegativeTemperatureCoefficient, negative temperature coefficient) thermal resistor, and it has multiple packing forms, it is possible to be applied to easily in various circuit.
Owing to fan size of air quantity in the unit interval also can affect the heat radiation of equipment, and air quantity refers to fan discharge per minute or the total volume of air included in, air pressure (or atmospheric density) will affect fan size of air quantity in the unit interval, and namely ambient pressure can characterize the atmospheric density under the air pressure conditions of equipment place environment, therefore the ambient pressure value of equipment place environment can also be one of ambient parameter for determining fan target rotating speed. Specifically, for the acquisition of the ambient pressure value of equipment place environment, it is possible to be obtained by barometric surveying, barometer can be arranged on the inside of equipment, or the ambient pressure value of equipment place environment can also be set in advance. Wherein, computing formula according to air pressure, the ambient pressure of equipment place environment is generally relevant with the height above sea level of equipment position, when practical application, ambient pressure generally changes less, therefore can by software be previously written ambient pressure value and or provide a user with change ambient pressure value software interface, thus obtain and change for determine fan target rotating speed equipment place environment ambient parameter in ambient pressure value.
In addition, ambient humidity also can affect the heat radiation of equipment, and when general humidity is more big, speed air flow reduces, the radiating rate of equipment is also relatively slack-off, and therefore the environmental wet angle value of equipment place environment can also be one of ambient parameter for determining fan target rotating speed. Specifically, for the acquisition of the environmental wet angle value of equipment place environment, it is possible to be obtained by humidity sensor measurement, wherein, the air inlet at equipment can arrange humidity sensor, can also arrange humidity sensor at the air outlet place of equipment.
Speed air flow is also relevant with environmental factorss such as the ambient wind velocities of equipment place environment, affect the ambient parameter of equipment cooling according to different demands and application scenarios, also difference to some extent, thus be accordingly used in the ambient parameter determining fan target rotating speed and can also comprise the parameter of ambient wind velocity value etc. some other and equipment place environmental correclation further, it is possible to the measurement of corresponding sensor is set in a device or presets.
On the other hand, owing to equipment is in different when laying attitude, between the heat dissipation wind channel for the air channel dispelled the heat and equipment and external environment that device interior is formed, the velocity of liquid assets of air there is also difference, therefore, equipment lay attitude parameter can also as one of parameter for determining fan target rotating speed.Such as, for general device, the air outlet and the air inlet that are provided with the equipment of fan are usually located at equipment and are just putting the side in attitude situation, under identical rotation speed of the fan, equipment is in the radiating effect just put in attitude situation and is generally in, by being better than equipment, the radiating effect that inclination is laid in attitude situation.
Specifically, in some embodiments of the present invention, can pass through to arrange in a device gravity sensor (G-sensor) measurement device on each change in coordinate axis direction in space by gravitational conditions, thus obtaining for reflecting the equipment initial parameter laying attitude in space, and further to these for reflecting that the equipment initial parameter laying attitude in space quantifies to obtain the equipment of one of the parameter for determining fan target rotating speed and lays attitude parameter. Concrete quantizing rule can according to the structure of the concrete placement location of equipment and equipment self, and the position etc. including air inlet, air outlet and fan is determined by experiment.
Further, owing to the thermal source of equipment is mainly the operating circuit part of equipment, the operating power of equipment is more big, and the heat produced in the unit interval is also more big, the radiating requirements of equipment also increases accordingly, and therefore the operating power of equipment can also as being used for one of parameter determining fan target rotating speed. Specifically, the operating power of equipment can be obtained by energy meter measurement, or by the operating current of the equipment obtained by amperometric measurement with pass through the running voltage that obtains of voltameter measurement and be multiplied and obtain.
Wherein, energy meter, or galvanometer and voltameter, the interior operating circuit part as heating source of the equipment that can be arranged on, such as, for laser projection device, laser instrument is as the heating source in laser projection device, substantial amounts of heat can be produced in the course of the work, and in laser projection device such as the part such as fluorescent wheel or eyeglass, it is then directly or indirectly receive the energy of laser and produce heat, therefore heat produced by these parts can consider in the impact on the total heat production of equipment of the operating power at laser instrument, therefore, energy meter, or galvanometer and voltameter, the laser circuit part in laser projection device can be arranged on, operating power in order to Laser Measurement device, such as, if being provided that galvanometer or voltameter, then galvanometer is in order to the driving electric current I of Laser Measurement device, voltameter is in order to the driving voltage U of Laser Measurement device, computing formula U according to power �� I can obtain the operating power of laser instrument.
In some currently preferred embodiments of the present invention, the parameter for determining fan target rotating speed can be obtained in real time or termly, also further can to accessed for determining that the parameter of fan target rotating speed stores, thus after getting the parameter for determining fan target rotating speed every time, can by this accessed be used for the parameter determining fan target rotating speed and storage before once get be used for determine that the parameter of fan target rotating speed contrasts, determine whether again to continue executing with follow-up flow process (flow process that namely step 102 and step 103 describe).
Such as, after getting the ambient temperature value for determining fan target rotating speed, the ambient temperature value once got before the ambient temperature value got and storage can be contrasted, if differing bigger, as exceeded default variations in temperature threshold value, then can continue executing with follow-up flow process, and if differ less than default variations in temperature threshold value, then can not perform follow-up flow process, thus realizing controlling corresponding to the rotation speed of the fan of variation of ambient temperature; Similar with ambient temperature value, environmental wet angle value for getting can also take above-mentioned judge process to judge whether to continue executing with follow-up flow process, and the operating power of the equipment for getting can also take above-mentioned judge process to judge whether to continue executing with follow-up flow process equally.
Again such as, lay attitude parameter due to equipment just to change when equipment lays attitudes vibration, therefore can detect this equipment got lay attitude parameter lay from the previous equipment of storage attitude parameter different time, continue executing with follow-up flow process, thus realizing laying the heat radiation adjustment of attitudes vibration corresponding to equipment;Attitude parameter is laid similar with equipment, due to atmospheric pressure value generally without change, or can be obtained by setting, therefore can when detecting that this atmospheric pressure value got is different from the atmospheric pressure value once got before storage, continue executing with follow-up flow process, thus realizing the heat radiation adjustment corresponding to air pressure change.
Step 102: according to the accessed parameter for determining fan target rotating speed, it is determined that the rotating speed of target of the fan installed in equipment.
In some embodiments of the invention, based on the parameter for determining fan target rotating speed accessed in a step 101, step 102 specifically can be determined by procedure below the rotating speed of target of the fan installed in described equipment:
To be multiplied with each influence coefficient corresponding for the parameter determining fan target rotating speed by each parameter for determining fan target rotating speed accessed by step 101, again the result after being multiplied is added up, obtain the first rotating speed of the fan installed in equipment, wherein, each influence coefficient corresponding for the parameter determining fan target rotating speed is set in advance; And then according to the first rotating speed, it is determined that the respective rotating speed of target of N number of fan installed in equipment, N is the integer be more than or equal to 1.
Wherein, owing to the ambient parameter of equipment place environment, equipment lay the operating power of attitude parameter and equipment for the impact of heat radiation it is believed that be independent from, and for heat radiation impact also different, by each parameter for determining fan target rotating speed accessed by step 101 for determining that the impact of fan target rotating speed is it is also assumed that be independent from, and each parameter for determining fan target rotating speed is for determining that the influence coefficient of fan target rotating speed is also difference to some extent. Although each parameter for determining fan target rotating speed is generally not simple linear relationship for the impact of heat radiation, accurate influence coefficient can be obtained in theory by complicated calculating, but for the consideration to cost, efficiency and practicality, in embodiments of the present invention, for each influence coefficient corresponding for the parameter determining fan target rotating speed, mode set in advance is taked to obtain. Specifically, each influence coefficient corresponding for the parameter determining fan target rotating speed can be determined by Heat Flow Experiment.
For example, assume by accessed by step 101 for determining that the parameter of fan target rotating speed includes ambient temperature value T, ambient pressure value P, equipment lay the operating power U �� I of attitude L and equipment, and assume to determine and set influence coefficient corresponding to ambient temperature value to be �� by Heat Flow Experiment1, influence coefficient corresponding to ambient pressure value is ��2, it is �� that equipment lays influence coefficient corresponding to attitude parameter3, the influence coefficient that the operating power of equipment is corresponding is ��4, then can process described in step 102, calculated the first rotating speed K of fan obtaining installing in equipment by below equation:
K=T �� ��1+P����2+L����3+U��I����4
In the other embodiment of the present invention, based on the parameter for determining fan target rotating speed accessed in a step 101, step 102 specifically can be determined by procedure below the rotating speed of target of the fan installed in described equipment:
By being multiplied with each influence coefficient corresponding for the parameter determining fan target rotating speed by each parameter for determining fan target rotating speed accessed by step 101, the result after being multiplied is added up; Again the cumulative result obtained is carried out computing with temperature-controlled parameter according to criterion set in advance, obtain the first rotating speed of the fan installed in equipment, wherein, each influence coefficient corresponding for the parameter determining fan target rotating speed is set in advance, and temperature-controlled parameter is set in advance; And then according to the first rotating speed, it is determined that the respective rotating speed of target of N number of fan installed in equipment, N is the integer be more than or equal to 1.
Wherein, to be multiplied with each influence coefficient corresponding for the parameter determining fan target rotating speed by each parameter for determining fan target rotating speed accessed by step 101, result after being multiplied is added up, can being identical with the process in aforementioned embodiments of the invention, each influence coefficient corresponding for the parameter determining fan target rotating speed can take mode set in advance to obtain. Shown in citing in such as aforementioned embodiments of the invention, it is K=T �� �� by carrying out the cumulative result obtained by each parameter for determining fan target rotating speed accessed by step 101 after being multiplied with each influence coefficient corresponding for the parameter determining fan target rotating speed1+P����2+L����3+U��I����4��
Under normal conditions, the temperature requirements of equipment self is relevant with the running parameter of the temperature of equipment place environment and equipment self, such as device temperature reaches 40 degree of temperature requirements namely meeting equipment work, then possibility will not further control the rotating speed of fan with further cooling, but if equipment is provided with the temperature-controlled parameter that can regulate, such as it is provided with the temperature-controlled parameter that can be artificially adjusted, if temperature-controlled parameter changes, such as corresponding temperature requirements improves (namely needing further cooling), then will be likely to the rotating speed needing to increase fan, therefore, temperature-controlled parameter is also an influence factor to fan target rotating speed.
In some specific embodiments of the present invention, consider the impact of temperature-controlled parameter further, by be multiplied with each influence coefficient corresponding for the parameter determining fan target rotating speed by each parameter for determining fan target rotating speed accessed by step 101 and the result after being multiplied is carried out cumulative after, further the cumulative result obtained is carried out computing with temperature-controlled parameter according to criterion set in advance, thus obtaining the first rotating speed of the fan installed in equipment.
Wherein, temperature-controlled parameter can be the parameter being configured by user, the temperature-controlled parameter of user setup is obtained as by the software interface providing user setup temperature-controlled parameter, temperature-controlled parameter can be specifically such as the value of multiple temperature shelves such as 30 degree, 35 degree, 40 degree, and user can be configured as required.
Specifically, temperature-controlled parameter can with in aforementioned embodiments of the invention for determining that the parameter of fan target rotating speed is similar, can have the influence coefficient of correspondence set in advance, and then can by the cumulative result obtained, the influence coefficient corresponding with temperature-controlled parameter and temperature-controlled parameter is multiplied the result obtained, it is added, the first rotating speed of fan being defined as in equipment installing the result added and obtain; Or, temperature-controlled parameter can also as a kind of control coefrficient on the whole to the cumulative result obtained, namely can preset the different control coefrficient value that different temperature-controlled parameters is corresponding, after being multiplied by control coefrficient corresponding with temperature-controlled parameter for the cumulative result obtained, obtain the first rotating speed of the fan installed in equipment. The control coefrficient that the value of temperature shelves different in such as temperature-controlled parameter is corresponding different, if the temperature under equipment normal operation requires is 40 degree, the value of 40 degree of temperature below shelves for control coefrficient may each be the control coefrficient value more than 1, specifically can also be determined by experiment, when other is for determining that the influence coefficient of fan target rotating speed remains unchanged, when control coefrficient that temperature control coefficient is corresponding is more big, the value of the first rotating speed obtained becomes big.
Further, in some embodiments of the invention, after calculating the first rotating speed of fan obtaining installing in equipment, it is possible to the respective rotating speed of target of N number of fan being defined as in equipment by the first rotating speed of fan installed in calculated equipment installing.
Due in actual application, N number of fan in equipment, when N is more than 1, when namely there is multiple fan in equipment, rotation speed of the fan also with fan location, the power (or running voltage of fan) of fan self, it is desirable to noise, if there is the many factors such as hot-air stream or some interference coming from equipment operating circuit relevant.
