The system comprises a singlechip, a camera, an infrared probe, a loudspeaker and interfaces, wherein the singlechip is respectively connected with the camera, the infrared probe and the interfaces bilaterally; the output end of the single chip is connected with the input end of the loudspeaker; a storage device can be added to the system for expanding memory; and the system is connected between a temperature controller and a switching valve of an air conditioner when in use. The infrared detection and image processing-based feedback control system is an externally added device, is used for detecting the existence of a human body and the closing situation of a window without influencing normal use of the air conditioner or redesigning the structure of the air conditioner, can make an alarm prompt sound, and has the characteristics of simple structure, low cost and good expansibility.
Description
Technical field
The present invention relates to a kind of feedback control system, relate in particular to a kind of feedback control system that is applied to air conditioner energy saving control, belong to the electrical equipment field of intelligent control based on infrared detection and image processing.
Background technology
At present, the problem of electric power resource anxiety day by day highlights, and air-conditioning is one of high energy consumption electrical equipment in the daily life.In the actual use of air-conditioning, some people does not close the window when not shutting down after leaving air-conditioned room or turning on the aircondition, and has caused waste of electric energy.
Existing air-conditioning can only detect indoor temperature, automatically start or close according to the temperature value of setting, reaching purpose of energy saving, whether have people or window whether to close such situation then can't to make judgement, therefore can't avoid the waste of energy problem of this type of situation for indoor.
Summary of the invention
Whether can't to indoor have people or window whether close the problem of making judgement and propose a kind of based on infrared detection feedback control system with image processing, make air-conditioning have stronger Based Intelligent Control ability if the present invention is directed to existing air-conditioning.
Feedback control system based on infrared detection and image processing of the present invention, its structure comprises: single-chip microcomputer, camera, infrared probe, loudspeaker and interface, wherein: single-chip microcomputer is connected with camera, infrared probe and interface are two-way respectively, the output of single-chip microcomputer connects the input of loudspeaker, and system is connected between the temperature controller and switch valve of air conditioner when using; The output of camera, infrared probe can be connected with the input of single-chip microcomputer by memory; Described camera and infrared probe are installed in by in the monolithic processor controlled adjusting rotating shaft; Described interface adopts USB interface.
Whether whether the present invention can make air-conditioning have people or window to close to make judgement for indoor, realize audio alert, do not influencing the waste of energy that minimizing causes because of human factor under the normal situation about using of air-conditioning, and need not the structure of air-conditioning is redesigned, only, therefore can be applicable to existing various air-conditioning as add-on device; Do not have precision instrument among the present invention, cost is lower, and is simple in structure, and detection range is big, and has good autgmentability.
Description of drawings
Fig. 1 is the structured flowchart of the embodiment of the invention.
Fig. 2 is a control flow chart of the present invention.
The specific embodiment
The structured flowchart of the embodiment of the invention as shown in Figure 1, comprise single-chip microcomputer, camera, infrared probe, loudspeaker, memory and interface, wherein: the output of single-chip microcomputer connects the input of camera, infrared probe and loudspeaker respectively, the output of camera and infrared probe all is connected the input of single-chip microcomputer by memory, single-chip microcomputer is connected with interface is two-way; The control input end of described single-chip microcomputer is connected with switch valve to realize air conditioner intelligent control with the temperature controller of air conditioner respectively with output.
The native system single-chip microcomputer adopts the C51 single-chip microcomputer, because C51 single-chip microcomputer internal memory is less, so adopt memory to enlarge internal memory, memory can adopt read-only storage ROM, random access memory ram or flash memory Flash; The temperature controller of air-conditioning and switch valve directly are connected on the single-chip microcomputer, are equivalent to add a Single-chip Controlling switch between the temperature controller of air-conditioning and switch valve; Adopting a camera and an infrared probe to be installed in regulates in the rotating shaft, regulating rotating shaft is rotated by Single-chip Controlling, Single-chip Controlling camera and infrared probe work, the image of camera and infrared probe collection and temperature information reach in the memory and handle for single-chip microcomputer; Interface adopts the USB general-purpose interface, makes things convenient for the read-write and the expansion of system; Loudspeaker is used for carrying out the audible alarm prompting.Native system is installed in the air-conditioning outside, as is fixed on the wall, can make detection range cover whole space by regulating rotating shaft.
Be control flow chart of the present invention as shown in Figure 2.Suppose that air-conditioning is in the stand-by operation state, at this moment temperature controller can detect indoor temperature, when indoor temperature is higher than design temperature, temperature controller will send instruction to system and device of the present invention, this moment, infrared detection was carried out in infrared probe work, and detected data are passed to memory analyze for single-chip microcomputer, single-chip microcomputer is judged according to predefined program: if judge the indoor thermal source that do not have, then send prompt tone (preventing to detect error), Single-chip Controlling air-conditioning switch valve is not opened, though at this moment but indoor temperature is higher than the design temperature air-conditioning and does not open, if single-chip microcomputer is judged the indoor thermal source that has, then camera is started working; The image information at the thermal source coordinate place of judging when camera obtains infrared detection, and pass to memory and analyze: if do not meet characteristics of human body's information for single-chip microcomputer, then send prompt tone (preventing to detect error), Single-chip Controlling air-conditioning switch valve is not opened, though at this moment but indoor temperature is higher than the design temperature air-conditioning and does not open, if the image information display thermal source is a window, then give the alarm to remind the user to close window, after infrared detection can detect thermal source and graphical analysis and is human body, single-chip microcomputer is promptly controlled the air-conditioning switch opening of valves, and air-conditioning carries out work.
System of the present invention is applicable to existing various types of air conditioners, and whether the unlatching of this system does not influence the normal use of air-conditioning, and the professional can make it to arrive best control effect by the interface update routine.
