As shown in Figure 2, it is the circle of 10CM that angle scale panel 23 is arranged in a radius by 12 little black filled circles (radius 0.5cm), the center of circle is placed one and is swept wind bar 21, sweep wind turbine to drive and sweep wind bar 21 and rotate, sweep the particular location that wind bar shows rotation in real time, react the operation conditions of motor with this, every two little black filled circles are separated by 30 degree.
This automatic monitored control system also comprises output device, and the output information of output module is showed by output device.Preferably, this output device is display.This central processing unit can adopt PC computer to realize, and related process module realizes by software programming in computer.
Refer to Fig. 4, as preferred embodiment, the automatic monitoring method of running state of air conditioner of the present invention comprises the steps:
(1) by camera head acquisition characteristics image, and the image capture module of central processing unit is sent to;
(2) characteristic image collected is sent to image pre-processing module and carries out Image semantic classification by image capture module;
(3) Iamge Segmentation and standardized module are split and standardization characteristic image;
(4) image characteristic analysis extraction module carries out signature analysis and extraction to through pretreated characteristic image, obtains characteristic value;
(5) characteristic value drawn identifies in feature comparison model, and exports the result identified.
This method is adopted to monitor display panel of air-conditioner, concrete:
(1) to two eight charactron identifications, such as numeral 25, refrigeration mode.
The first step: by camera Real-Time Monitoring display board, gathers image, and display board image comprises two eight charactrons, air conditioning operating mode signal pattern and power supply signal, image size: 240*320;
Second step: to input image restore, denoising, concrete operations have: white balance, image smoothing, enhancing, gray processing, binaryzation, Morphological scale-space, obtain binary image;
3rd step: find 2,5, refrigeration lamp, heat the border of lamp, dehumidifying lamp, and calibrate 2,5, refrigeration lamp, heat lamp, dehumidifying lamp.According to refrigeration lamp, heat lamp, dehumidify each regional percentage size shared by dim color pixel, identifying is which lamp is bright, in this example: refrigeration lamp ratio value be heat lamp, namely dehumidifying lamp ratio value 3 times more than is thought to freeze.5*5 template image is standardized into respectively by 2,5;
4th step: calculate each zonule black pixel value, and divided by the area of this zonule, namely obtain the ratio value of black picture element shared by this zonule, and first 5 of feature are saved according to 5 ratio values of the first row, second row correspond to 6 ~ 10 of feature, the like, obtain 5*5=25 characteristic value thus, characteristic value number is too many, amount of calculation is too large, needs to extract principal character value, can carry out horizontal and vertical projection to image, respectively can obtain 5 features, altogether 10 features;
5th step: respectively the feature of 2 and 5 is input in feature comparison model, identify, export as binary number 0010 for 2, export as this binary number of 0101(is oneself definition for 5, might not be correspond to the binary value in computer, but value be all one to one)
Because the signal lamp on display board is relative fixing with two eight charactron positions, after orienting the position of two eight, the latter half (square display board) of image or right half part (microscler display board) within the specific limits pixel and threshold decision orient the position of signal lamp, when pixel and institute's accounting are greater than 0.1, then think that the signal lamp of region is effective.
(2) to sweeping wind turbine angle device:
By camera collection angle scale panel image, detect the position of sweeping wind bar in real time, calculate front and back two frame through too small black filled circles number and the relative position sweeping wind bar and two little black filled circles, as left figure, angle is n*30+ offset angle.Offset angle can be determined by the distance proportion of rotating shaft to adjacent two little black filled circles.
As shown in Figure 5, when system initialization, it also comprises the step setting up feature comparison model, namely training pattern.Training comprises all characters that will identify, in the present embodiment, comprising: 0-9, C, E, F, H, P, U 16 characters, and for ensureing that error can reach requirement, each character needs training 80 times.
Training example: 5, idiographic flow is as follows:
First: by camera collection image, image size: 240*320;
Second: to input image restore, denoising, concrete operations have: white balance, image smoothing, enhancing, gray processing, binaryzation, Morphological scale-space, binaryzation etc.;
3rd: on acquisition bianry image, find 5 on image original position, i.e. border, and demarcate out, be standardized into 5*5 template image;
4th: calculate each zonule black pixel value, and divided by the area of this zonule, namely the ratio value of black picture element shared by this zonule is obtained, and first 5 of feature are saved according to 5 ratio values of the first row, second row correspond to 6 ~ 10 of feature, the like, obtain 5*5=25 characteristic value thus, characteristic value number is too many, and amount of calculation is too large, needs to extract principal character value, horizontal and vertical projection is carried out to image, respectively can obtain 5 features, altogether 10 features, be saved in TXT file; And being standardized into 5*5 module map picture, the black picture element calculating each piece is counted;
5th: model is set up, native system adopts Back propagation (to be called for short: BP) neutral net, network structure has three layers: input layer, hidden layer, output layer.Characteristic is 10, and therefore input node is 10, and hidden layer node is 11, and output layer node is 4, and these four outputs are 4 bits, represents the numeric type that neutral net exports.In this example, 5 corresponding outputs 0101;
6th: model training, each character feature value is input to model, and calculate hidden layer, the weights of output layer and error, error constantly revises the input value of input layer and hidden layer node, output valve and each tutor's signal (namely corresponding character, be 5 in this example) until error reaches system requirements, maximum frequency of training 80.
In the present embodiment, the present invention passes through the image of two camera Real-time Collection display boards and angle scale panel, by video procession technology, export in real time the state of the signal lamps such as two eight numerals, patterns on the display board after identifying and sweep the angle of wind turbine.Instead of manual monitoring, increase work efficiency and monitor accuracy.
The foregoing is only preferred embodiment of the present invention, protection scope of the present invention is not limited thereto, and anyly all belongs within scope based on the equivalent transformation in technical solution of the present invention.
