[ An interface module 200 including an operation unit of the equipment, a monitor 300 for displaying an image transmitted from the external monitoring camera, and an output abnormality detection unit And a webcam 310 for identifying the user.
Prior to describing the main constitution of the present invention, the description of the basic constituent elements will be preceded.
The interface module 200 is composed of an operation button, an input / output port, a power port, and the like, and plays a role of taking charge of input / output with respect to utilization and operation of the apparatus.
The monitor 300 serves to visually display an image transmitted from an external surveillance camera on the screen and to display a setting menu or the like when a user sets an apparatus using an operation button or the like.
The webcam 310 is provided in front of the monitor 300 to photograph the monitor 300. The photographed image is stored in the storage unit by the self-diagnosis module 100, It is used for image check.
Although the surveillance camera is not included in the configuration of the present invention, it is provided to utilize the present invention. The surveillance camera is installed at any point outside and photographs the vicinity of the installation point, To an all-in-one recording apparatus equipped with a diagnostic function. At this time, it is preferable that the surveillance camera is installed in a fixed manner, and any one of known surveillance cameras such as an ip camera can be adopted and utilized.
The self-diagnosis module 100 analyzes the fault area and the fault type, generates a fault code corresponding to the fault, and notifies the fault to the control center. For this, the fault checking unit 120 and the image Instructs the check unit 130 to perform the diagnosis, receives the results of the diagnosis execution from the failure check unit 120 and the image check unit 130, analyzes the results, and determines whether there is a failure.
First, the self-diagnosis module 100 instructs the failure check unit 120 to check the failure of each accessory whenever a predetermined time or a request is made from the control center. The information returned from the failure check unit 120 includes status information such as temperature of a storage unit such as a hard disk for recording an image, voltage status information of a power port, status information such as temperature of each chipset, Information on the physical state of the hardware components, such as information on the signal presence / absence of the external monitoring camera connecting cable.
Based on this information, the self-diagnosis module 100 can diagnose faults such as the connection state of each component of the device, the abnormal operation state such as overheating, and the like. The ID, GPS position information, The installation number of the fault, the fault location matched to the diagnosis result, and the fault type. For example, when the voltage value of the power port returned from the failure check unit 120 exceeds the set error range as a result of checking the voltage state of the power port, the self-diagnosis module 100 transmits a failure of the power port to the control center .
Next, the self-diagnosis module 100 instructs the image check unit 130 to check the image every time a predetermined time or a request is made from the control center. At this time, there are two kinds of check of the image to be performed, one is the image check of the surveillance camera, and the other is the check of the image displayed on the monitor 300.
First, when performing the image check of the surveillance camera, the self-diagnosis module 100 transmits the image used in the previous image check to the image check unit 130. [ When the processed image is returned from the image check unit 130, the processed image is stored in the storage unit as a reference value, and the image captured and stored in the current real time is transmitted to the image check unit 130 again. After the processed image is processed by the image check unit 130 and the processed value is returned, the result is stored in the storage unit as a comparison value, and the reference value and the comparison value are transmitted to the image check unit 130 for comparison. If the difference between the reference value and the comparison value is less than the set value, for example, when the similarity rate in the normal state is set to 70% or more, if the similarity rate is less than 70%, the surveillance camera is judged to be faulty, do.
Meanwhile, in order to increase the efficiency of the surveillance camera, the comparison value of the real-time image used in the previous image check is stored in the storage unit, and the current value is used as the reference value when checking the current image. After storing the comparison value of the image in the storage unit, it may be used as a reference value when checking the next image.
Secondly, in the case where the image check of the monitor 300 is performed, the self-diagnosis module 100 photographs the screen currently displayed on the monitor 300 using the webcam 310 provided in front of the monitor 300 And transmits it to the image check unit 130. It is preferable that the self-diagnosis module 100 stores the image of the monitor 300 photographed using the webcam 310 in the storage unit when setting the initial equipment. The self-diagnosis module 100 transmits the image of the monitor 300 photographed using the webcam 310 to the image check unit 130 when the initial equipment setting is performed, And stores it as a reference value in the storage unit. Then, the image of the currently captured monitor 300 is transmitted to the image check unit 130, and if the processed value is returned from the image check unit 130, it is stored in the storage unit as a comparison value. Thereafter, the self-diagnosis module 100 transmits the stored reference value and the comparison value to the image processing unit, compares the comparison value, and if the difference between the reference value and the comparison value is less than the set value, for example, the similarity rate of the normal state is set to 70% , And if the similarity rate is less than 70%, it is determined that the monitor 300 is malfunctioning, and it is notified to the control center.
In order to increase the efficiency of the monitor 300, the monitor 300 transmits the image of the monitor 300 to the image check unit 130 in advance to generate a reference value, The comparison value used at the time of image check of the previous monitor 300 may be utilized as a reference value at the time of checking the image of the next monitor 300. [

When the image is transmitted from the self-diagnosis module 100 and the image processing command is received, the image check unit 130 digitally converts the transmitted image to generate an output value. In this case, the image processing is performed by dividing the image into a plurality of rectangular regions and then obtaining the histogram value or the DC and AC component values of the 2D FFT for the image of the specific region set in the plurality of regions.
To be more specific, the image check unit 130 divides the image so that a plurality of blocks are arranged in rows and columns so that the upper and lower rectangular blocks can be formed with respect to the transmitted image. A histogram value or a 2D FFT (two-dimensional fast Fourier transform) according to histogram processing is applied to a block of a predetermined position among the divided blocks, for example, non-contiguous blocks including four edges, And a DC component value and an AC component value according to the following equation. At this time, the selection of a block to obtain the histogram value or the DC and AC component values of the 2D FFT is determined in advance by the self-diagnosis module 100, and a block at the same position is selected each time the monitoring camera image is checked or the monitor 300 is checked. A minimum of 4 to 9 blocks may be selected, but not limited thereto, so that the processing of the image can be performed quickly and the comparison of images can be accurately performed.
At this time, the calculation of the histogram value is known from Patent No. 10-0883544, No. 10-0369370, and No. 10-0265722, and the calculation of the DC component and the AC component value according to the conversion of the 2D FFT 10-0240295, and 10-1038639, the detailed description thereof will be omitted.
If the reference value and the comparison value based on the DC component and the AC component value according to the conversion of the histogram value or the 2D FFT are transmitted from the self-diagnosis module 100, the image check unit 130 compares the two values, And transmits the calculated result to the self-diagnosis module 100, or when the similarity rate is less than the set value, the image mismatch result is provided to the self-diagnosis module 100.
First, the self-diagnosis module 100 checks for failures of component parts and checks images at predetermined times for each line in which the surveillance camera is installed. Then, the self-diagnosis module 100 transmits the ID information, the GPS information, and the diagnosis result information of the facility where the surveillance camera is installed according to the checked result to the control center in one byte by using the corresponding code. After that, the control center makes it possible for the administrator to directly check the diagnosis result information in the event of an abnormality in the equipment, and generates a log file so that the administrator can maintain the equipment based on the log file in the future.
