The scheme is designed to use the EC20 communication chip which supports 4G LTE, 3G WCDMA and 2G GSM/GPRS/EDGE networks and has the characteristics of high-speed data transmission, low power consumption, high reliability and the like. The EC20 communication chip realizes a remote data transmission function through the SIM card, supports a downlink rate of up to 150Mbps and an uplink rate of 50Mbps, supports various interfaces and protocols, and can easily meet the transmission of the image data of the device lamp. In addition, the EC20 communication chip also has various security mechanisms, such as SSL/TLS, IPsec, VPN and the like, and can effectively ensure the secure transmission of data.
The EC20 communication chip is connected with a Universal Asynchronous Receiver Transmitter (UART) on the main control chip to receive and transmit data; the universal connection asynchronous transceiver is used for serial communication; when data is transmitted, the CPU writes parallel data into the UART, and the UART serially transmits the parallel data on one line according to a specific format; when receiving the instruction, the UART detects the electric signal of the other wire, collects the instruction and places the instruction in the buffer area, and the on-vehicle data processing module reads the buffer area to obtain the instruction.

Huffman coding is a variable length prefix code. In short, huffman coding uses a special method to set a binary code for each symbol in a signal source, a symbol with a larger frequency of occurrence will obtain shorter bits, and a symbol with a smaller frequency of occurrence will be allocated longer bits, so as to improve the data compression rate and the transmission efficiency. When the Huffman coding is decoded, a coding table is also required to be generated in advance, and when the coding table is combined with frequency correlation and prefix non-repetition (prefix-free), a binary tree optimal for a certain text is constructed, and the tree is called a Huffman tree (Huffman tree), so that Huffman coding is optimal prefix coding in theory.

and the ground terminal system receives and processes the information sent back by the vehicle-mounted recording equipment, identifies the display state of the lamp position of the equipment, analyzes the display state, and intercepts video data at the abnormal moment to alarm after the abnormality is found.
Example 4
The intelligent diagnosis and analysis method for recording the lamp position state information of the train control vehicle-mounted equipment is based on the system and is characterized in that:
s1, acquiring lamp position state information of train control vehicle-mounted equipment through one or more sets of vehicle-mounted recording equipment, performing digital compression processing, and transmitting image data to a ground terminal system through a wireless transmission module;
s2, the ground terminal system receives and processes related data transmitted back by the vehicle-mounted recording equipment of the multiple trains of motor train units simultaneously, and periodically transmits time information and data request instructions to the vehicle-mounted recording equipment on each vehicle side;

The ground terminal system consists of hardware equipment and a software system, wherein the hardware equipment consists of a power module and an information transmission module, and the related information data of the train control vehicle-mounted equipment of the multiple trains of motor train units can be received simultaneously by adopting one-to-many design. The software system mainly comprises a data processing system and a man-machine interaction interface, wherein the data processing system adopts an OpenCV image processing technology to recognize the state information of the lamp position of the equipment frame by frame, compares the state information with the state of the lamp position of the equipment which is input into a system information base in advance, and intercepts video at abnormal time after abnormality is found and outputs the video to the man-machine interaction interface.
As shown in fig. 1, the vehicle-mounted recording device comprises a lamp position acquisition module, a temperature and humidity recording module and a data processing module which are in one-way communication, and the lamp position state and the working environment information of the device are provided by the vehicle-mounted recording device. The data processing module is communicated with the wireless transmission module through an internal bus, and the wireless transmission module transmits data to the ground terminal system. The in-vehicle recording device records and stores the device light bit state at a period of 30s, generating a recorded data file.
For example, as shown in fig. 2, a ground data processing system in the ground terminal system is responsible for identifying and processing the lamp position state information returned by the vehicle-mounted recording device, and storing the identified data. The ground data processing system continuously records and stores the data after the identification processing in the form of a file with the length of 30s, and if the abnormality is found after the identification, the ground data processing system outputs an alarm to the human-computer interaction interface.
For example, as shown in fig. 3, the Open CV-based image processing method identifies video images frame by frame according to the procedures of image color YCrCb component splitting, image erosion and dilation processing, image contour extraction, and position location. And comparing and analyzing the identified image with cases in the information base through logic judgment, and timely finding out abnormality.
The content of the image processing algorithm based on the Open CV comprises:
initializing configuration: calling a CV2.Video capture function in the Open CV to read in video stream from a camera of the lamp position acquisition module in real time; setting a frame rate of capturing video frames by calling a cv2.CAP_PROP_FPS function at the same time; and then, the brightness parameters are set, and the video brightness of the lamp position state of the equipment is adjusted frame by frame so as to facilitate the subsequent easier splitting of the image colors.
The treatment is mainly divided into two steps; step one, removing various noise and interference in an image; step two, identifying red, green and yellow image blocks in the image, wherein the red and green image blocks are equipment lamp position display color blocks, and the yellow image blocks are positioning color blocks;
the principle of the method is that the Gaussian noise in the captured video image is removed by calling a cv2.Gaussian Blur Gaussian filter function in the Open CV, and the principle is that each pixel in the image is calculated by weighting average based on the Gaussian function, namely, the pixel which is far from the center pixel has smaller weight, the pixel which is close to the center pixel has larger weight, so that the noise is removed while the image edge information is kept. The two-dimensional Gaussian function distribution formula is as follows:the standard deviation of the width of the gaussian filter can be determined by σ, and the larger σ is, the wider the band of the gaussian filter is, and the better the smoothness is. The gaussian filter formula is: f (u, v) =f (u) i ,v j )×g(u i ,v j ) (i, j ε W). Where f (u, v) is the center pixel value of the image region corresponding to the Gaussian template, f (u) i ,v j ) For pixel values of the image region corresponding to the Gaussian template, g (u i ,v j ) The weight in the Gaussian template is represented by W, which is the template size.
Step two: and calling a cv2.Cvtcolor color space conversion function in the OpenCV, converting the image from an RGB color space to a YCrCb color space, traversing all pigments in the image through Cr components, and respectively splitting red, green and yellow pigment blocks, thereby facilitating the feature extraction of three colors of red, green and yellow. The YCrCb color space is a color space in which one luminance signal and two chrominance signals are represented using three components, Y, cr and Cb, respectively. The following formula is used for converting the RGB color space:
erosion and expansion treatment: after the above color splitting processing step, three gray-scale images with red color blocks, green color blocks and yellow color blocks can be obtained, firstly calling the tile () expansion function in Open CV, and combining all background points contacted with the color blocks into the color blocksThe color block is enlarged, and the hole in the color block is filled. The specific operation is as follows: each pixel in the image is scanned with one structural element, and each pixel in the structural element is anded with the pixel it covers, if both are 0, then the pixel is 0, otherwise 1. The formula is as follows: [ epsilon ] B (X)](x)＝min{X B [ epsilon ] in the formula ] B (X)](x) Representing the process of the structural element B eroding the sub-element X from the set X, min representing the minimum value, X B Representing the value of x within structural element B.
And then, invoking an erod () erosion function in the Open CV to eliminate the boundary points of the color blocks, so that the color blocks are reduced and the boundary of the color blocks is strengthened. The specific operation is as follows: each pixel in the image is scanned with one structural element, and each pixel in the structural element is anded with the pixel it covers, if both are 1, then the pixel is 1, otherwise 0. The formula is as follows: [ delta ] B (X)](x)＝max{X B [ delta ] B (X)](x) The expansion operation of the structural element B on the subelement X of the set X is performed, and ma represents the maximum value.
The erosion expansion treatment can effectively carry out noise reduction treatment on the binary image, and because the interior of the cabinet is in a dark state for a long time, the operation of expanding first and then eroding is adopted, tiny black holes are removed, and a bright indicator light area is better reserved.
Profile extraction processing: in Open CV, threshold segmentation of the OTSU scheme can be achieved by calling the cv2.thresh_otsu function. The OTSU algorithm is a method for automatically determining a threshold value by using the maximum inter-class variance, and is a global-based binarization algorithm, which divides a color block image into a foreground part and a background part according to the gray scale characteristics of the color block image. The difference between the two parts is greatest when the optimal threshold is taken. The derived formula is: g=w 0 *(1-w 0 )*(u 0 -u 1 ) 2 W in 0 Is the proportion of foreground points, so 1-w 0 For the proportion of background points, u 0 As the foreground gray level average value, u 1 As for the background gray average value, g is an objective function, and the larger g is, the better the threshold value is. Therefore, the optimal threshold can be obtained by traversing the gray scale of 0-255 once.
And (3) intersection judgment: and searching the shortest distance between the midpoint of the two color blocks and the contour line by using a CV2.PointPolygonTest function in the Open CV to judge whether the positions of the red and green image color blocks are overlapped. Because the same indicator lamp can only display one color at the same time, the condition of high overlapping of the red and green images is eliminated by the intersecting judgment, and the recognition accuracy is increased.
Position determination: the specific positions of the recognized red and green images are precisely determined by calling a CV2.Pointpolygon test function in the OpenCV and utilizing a yellow positioning pattern attached to the device, and the indication states of all pairs are precisely recognized.
Comparison of results: comparing the identified equipment lamp position information with equipment lamp position state information cases in a system information base, and carrying out the process according to each preset flow for the conditions existing in the information base; and alarming the condition which does not exist in the information base, prompting manual processing, and storing the processing result into the information base for subsequent use.
