Embodiment
As shown in Figure 1, 2, a kind of Novel projector box, comprise casing 1, thermovent 2, fixed installation hole 3 and attemperating unit, described casing 1 is made up of top cover, base plate, Qianmen, back door and two blocks of side plates, described thermovent 2 is positioned on two blocks of side plates of described casing 1, described fixed installation hole 3 is positioned on the top cover of described casing 1, and described attemperating unit is installed on described casing 1 inside
Described attemperating unit comprises controller 4, temperature sensor 5, the first relay 6, the second relay 7, refrigerating plant 10, heat abstractor 11, delay protection circuit 8 and independent current source 9,
Described heat abstractor 11 is positioned at described casing 1 back door, and described refrigerating plant 10 is positioned at described casing 1 top cover,
Described temperature sensor 5 is connected with described controller 4; described controller 4 is connected with described the first relay 6, the second relay 7 respectively; described the first relay 6 is connected with described heat abstractor 11; described the second relay 7 is connected with described refrigerating plant 10; described independent current source 9 is connected with described delay protection circuit 8, and described delay protection circuit 8 is connected with described refrigerating plant 10, heat abstractor 11 respectively.
Also comprise electric time-keeping display device 12, described electric time-keeping display device 12 is connected with described controller 4.
Described heat abstractor 11 is fan.
Described refrigerating plant 10 is heating radiator.
Described temperature sensor 5 is 1-wire digital temperature sensor.
Described thermovent 2 is provided with Air Filter.
In most preferred embodiment; describedly comprise casing 1, thermovent 2, fixed installation hole 3 and attemperating unit for intelligent temperature control hoisting box for projection instrument, described attemperating unit comprises controller 4, temperature sensor 5, the first relay 6, the second relay 7, refrigerating plant 10, heat abstractor 11, delay protection circuit 8 and independent current source 9.Its middle controller 4 is measured the temperature in casing 1 by temperature sensor 5, and then controls refrigerating plant 10, heat abstractor 11 and work, and reaches the temperature of controlling casing 1.Independent current source 9 is powered for refrigerating plant 10, heat abstractor 11, and when after projector power-off, delay protection circuit 8 is worked, and makes, and it is attemperating unit power supply that independent current source 9 continues the regular hour, and projector is dispelled the heat completely, extends its serviceable life.And electric time-keeping display device 12 duty of display system in real time, for user's use is provided convenience.Wherein heat abstractor 11 is arranged on casing 1 back door, and refrigerating plant 10 is fixed on to casing 1 top cover, and thermovent 2 places that arrange in casing 1 both sides paste Air Filter.Attemperating unit also comprises controller 4, temperature sensor 5, the first relay 6, the second relay 7.
Preferably, controller 4 is taking the STM32F103 of high-performance/cost ratio as core, the analysis of complete paired data, processing, demonstration, the setting of temperature bound, transfinites and automatically controls; Temperature sensor 5 adopts 1-wire digital temperature sensor DS18B20 to complete sampling and the conversion to temperature.Thereby make whole digital control implement control simple and convenient, measurement range is wide, precision is high.
Preferably, heat abstractor 11 is fan, and refrigerating plant 10 is heating radiator.Heating radiator does main devices with the little semiconductor chilling plate C1206 of volume, the cold air that heating radiator can produce cooling piece is timely blown in projector suspension bracket casing 1, also also can in time hot gas be got rid of, laboratory test shows under normal power, after device start, in 30 seconds, can weaken intensification trend, in 2 minutes, start cooling, in 10 minutes, just can make the temperature of projection box be reduced to below preset temperature.
In addition, electric time-keeping display device 12 is connected with described controller 4, facilitates the intuitively parameters of inquiry understanding intuitively of user, the service condition of adjustment System.
The invention is that the intellectuality that a projector is used can be antitheft, dustproof temperature control box, in casing 1 structural design, radiator fan is arranged on after casing 1, be because the thermovent 2 of projector in the back, be conducive to like this heat and discharge fast casing 1 outside, refrigerating plant is arranged on to casing 1 top, be conducive to like this cold air and sink to whole casing 1, reach the object of quick effective temperature-reducing, at casing 1, larger area thermovent 2 is installed, Air Filter is affixed in thermovent 2, so not only can prevent dust but also can dispel the heat well, can ensure again the anti-theft feature of casing 1.
Aspect temperature control, before using, first need to preset early warning temperature according to user, the course of work is sampled and changes the interior temperature of casing 1 by temperature sensor 5, give controller 4 by measurement result, the temperature value of input is carried out data processing by controller 4, and the temperature value bound of temperature value and setting is compared.Process accordingly according to comparative result.One group of experimental data is: in the time of measured temperature >=40 DEG C, and the first relay 6 adhesives, heat abstractor 11 starts, if casing 1 temperature rises to more than 55 DEG C, controls the second relay 7 adhesives, starts refrigerating plant 10 and lowers the temperature.If what temperature was more stable remains on below 55 DEG C, do not start refrigerating plant 10.Heat abstractor 11 was worked after a period of time, if when measured temperature < setting value-return difference value, the first relay 6 disconnects, and heat abstractor 11 stops, and equipment moves returning in difference range.For example return difference value is set 15 DEG C, the second relay 7 closures after powering on, refrigerating plant 10 starts, when refrigeration is to below 50 DEG C time, the second relay 7 disconnects, refrigerating plant 10 cuts out, now because refrigerating plant 10 has disconnected, and temperature bottom out, in the time going back up to 60 DEG C of setting values, the second relay 7 closures, refrigerating plant 10 starts again, and so iterative cycles control temperature is not higher than 60 DEG C.This equipment cost performance is high, and stable performance can extend the projector life-span, realizes hommization operation.
Above the embodiment of the invention is had been described in detail, but described content is only for the preferred embodiment of the invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the invention scope, within all should still belonging to this patent covering scope.
