Description

Utilize the method for infrared temperature-test technology control air-conditioning
Technical field
The present invention relates to the air-conditioner field, relate in particular to the method for utilizing infrared temperature-test technology control air-conditioning.
Background technology
At present, the indoor apparatus of air conditioner wind pushing mechanism all is to measure air-conditioning environment temperature on every side by mounting temperature sensor on air-conditioning to the measurement of environment temperature mostly.In the reality, temperature sensor just measures the indoor set temperature in very little space on every side, with bigger error of true temperature existence of entire environment.
Infrared temperature-test technology is still the cutting edge technology of a high technology content at present at home and abroad, mainly the infrared ray that emits by the measurement object is realized the measurement to object temperature, has the certainty of measurement height, characteristics such as applied range, be mainly used in the contactless aspects such as temperature survey of iron and steel, electric power system etc. at present, and it is also fewer to be applied to the field of air conditioning product.
Chinese patent has disclosed a kind of air conditioner and method of operating thereof according to the control of infrared ray quantity for 02122689.X number.The main technical schemes of this patent disclosure is: on the shutter board of infrared detector attached to air conditioner, infrared detector is with the infrared ray quantity in a plurality of spaces in the driving measuring cell of shutter board, and then according to the result who measures, by the operation of microcomputer control air conditioner, thereby realize the purpose that intelligence is regulated.
Yet in the above-mentioned technology, infrared detector is the driving that is subjected to shutter board, is subjected to bigger restriction so it detects the space and detects the free degree; In addition, above-mentioned technology only is that environment temperature is carried out sensing, can't accomplish to come according to the surface temperature of human body self in the environment adjustment of intelligence, and it designs not enough hommization.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the air-supply of infrared temperature-test technology control air-conditioning.
For achieving the above object, the method for utilizing infrared temperature-test technology control air-conditioning provided by the invention is characterized in that comprising the steps: that (1) utilizes the infrared temperature-test sensor of installing on the air-conditioner that environment temperature is measured, and obtains environment temperature; (2) utilize the surface temperature of the infrared temperature-test sensor measurement environment internal object human body of installing on the air-conditioner, obtain the surface temperature of target body; (3) according to the pushing wind manipulation of the parameter control air-conditioning of the surface temperature of above-mentioned environment temperature of obtaining and human body.
As mentioned above, the present invention utilizes the infrared temperature-test sensor of installing on the air-conditioner that environment temperature and human surface temperature are measured respectively, by the measured result of analysis-by-synthesis, and then the pushing wind manipulation of control air-conditioner.The present invention is according to the wind pushing temperature of the temperature intelligent control air-conditioning of environment temperature and human body surface, solved the traditional problem that can only adjust wind pushing temperature according to the temperature around the air-conditioning, wind pushing temperature changes because of the variation of human surface temperature in the environment simultaneously, make the people feel more comfortable, can be good at improving wind pushing temperature along with the decline of human body temperature, perhaps out-of-blast, can also reach the purpose of energy savings.

SECO flow chart when Fig. 3 specifically implements on air-conditioner for the present invention.
The specific embodiment
Among the present invention, infrared temperature-test sensor is installed on indoor apparatus of air conditioner, and is reserved the interface that carries out transfer of data and auxiliary control at the air-conditioning microcomputer.Infrared temperature-test sensor is used for the surface temperature of sense ambient temperature and environment internal object human body, and obtains data.The surface temperature of environment temperature that microcomputer analysis obtains and environment internal object human body, and then the control indoor apparatus of air conditioner is carried out corresponding pushing wind manipulation.Among the present invention, infrared temperature-test sensor is driven by a rotating mechanism, can freely carry out sensing to a plurality of orientation.In addition, the present invention also provides another external communication interface, is used to obtain coordinate or integrated this part function of environment internal object human body.
The method of utilizing infrared temperature-test technology control air-conditioning provided by the invention comprises the steps:
(1) utilizes the infrared temperature-test sensor of installing on the air-conditioner that environment temperature is measured, obtain environment temperature;
(2) utilize the surface temperature of the infrared temperature-test sensor measurement environment internal object human body of installing on the air-conditioner, obtain the surface temperature of target body;
(3) according to the pushing wind manipulation of the parameter control air-conditioning of the surface temperature of above-mentioned environment temperature of obtaining and human body.
See also Fig. 1, the environment temperature of obtaining described in the above-mentioned steps (1) is meant the mean temperature of environment, and step (1) specifically comprises: start rotating mechanism, utilize certain regional temperature in the infrared temperature-test sensor measurement environment; The rotation of adjustment infrared temperature-test sensor, the temperature in a plurality of zones in the test environment, the mean temperature of computing environment.
See also Fig. 2, the surface temperature of the target body of obtaining described in the step (2) is meant the mean temperature on target body surface, and step (2) specifically comprises: the coordinate of determining target body; Regulate rotating mechanism, utilize the surface temperature of infrared temperature-test sensor measurement target human body multiple spot, calculate the mean temperature on target body surface.
Step (3) specifically comprises: the mean temperature of the environment that is obtained by the control of microcomputer software analysis and the mean temperature on target body surface, and judge whether to adjust leaving air temp, if then adjust the wind pushing temperature of air-conditioning, if otherwise judged whether to adjust the air-supply wind direction, if would then adjust the air-supply wind direction.Do not have target body to exist in the environment if external communication interface is checked through, then reduce the power consumption of air-conditioning or close air-conditioning.
Figure 3 shows that the SECO flow process when this method is specifically implemented on air-conditioner.At first, start the intelligent infrared temperature-measuring function, initialization air-supply control module, initialization infrared measurement of temperature module, initialization timing device module, other auxiliary control modules of initialization; Then, timer interrupts, and changes ambient temperature measurement service routine and target body surface temperature measurement service routine (consulting Fig. 1 and Fig. 2) over to; Analysis environments temperature data and target body surface temperature data, and judge whether to adjust leaving air temp, if then adjust the wind pushing temperature of air-conditioning, if otherwise judge whether to carry out other control actions, as regulating wind direction etc.; Afterwards, return the timer interrupt step, so repeatedly, up to closing the intelligent infrared temperature-measuring function.
