Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The technical solution of the present invention is described below with reference to the specific embodiments and the accompanying drawings.
Example 1
As shown in fig. 1, a control system of an escalator for rail transit according to embodiment 1 of the present invention includes:
the image acquisition module 1 is used for acquiring image data of a station in real time, wherein the image data is used for indicating passenger flow density, passenger flow moving speed, passenger conditions on an escalator and article conditions on the escalator in different areas in the station.
Specifically, the image acquisition module 1 comprises a camera and a video collector, and is used for acquiring the passenger flow density and the passenger flow direction in different areas of a station and the conditions of passengers and articles on an escalator, and uploading monitored and acquired data to the image analysis module 2 in real time through the signal transmission module.
More specifically, the visual recognition algorithm of the image acquisition module mainly comprises: crowd density extraction, human body action abnormity detection and pedestrian detection and tracking, and object retention detection. The visual identification algorithm of the station passenger flow identification device mainly relates to the following steps: crowd density extraction, pedestrian detection and tracking.
(1) Crowd density (passenger flow density) extraction method
The algorithm is mainly divided into two parts: feature extraction and feature classification. The feature extraction comprises wavelet transformation and gray level co-occurrence matrixes, and the support vector machine is used for classification.
Firstly, 3-level wavelet decomposition is carried out on a crowd image, 9/7 filter banks are adopted to carry out three-level wavelet transformation, nine high-frequency sub-bands are used as the basis of feature extraction, and texture features are extracted from the nine sub-bands respectively. The detail subgraphs with different resolutions can display the texture condition of the crowd image in different directions.
In the texture image, the statistical probability of the common occurrence of a pair of pixel gray scales separated by a certain distance in a certain direction can reflect the texture feature of the image. The gray level co-occurrence matrix method is an important texture analysis method based on the second-order joint conditional probability density function of the estimated image. The gray co-occurrence matrix p (i, j | d, phi) is defined as the probability (or frequency) of a gray value j at a point that is a fixed position (separated by a distance d, azimuth phi) away from the point with the gray value i. Corresponding to the texture image with slow change, the value on the diagonal line of the gray level co-occurrence matrix is larger; and corresponding to the image with fast texture change, the value on the diagonal line of the gray level co-occurrence matrix is small, and the values on the two sides of the diagonal line are large.
The gray level co-occurrence matrix p (i, j | d, phi) reflects the comprehensive information of the image gray level distribution on the direction, the local neighborhood and the variation amplitude, but the data volume is too large, and the data volume is generally not directly used as the characteristic for distinguishing the texture, but some statistic is constructed on the basis of the data volume as the texture classification characteristic, the corresponding statistical texture characteristic is calculated, the characteristic vector is generated, and the characteristic classification is carried out by utilizing a support vector machine to obtain the crowd density level.
(2) Method for detecting human body action abnormity
When a person enters a detection area, the camera acquires a target, performs position positioning on the target and performs certain calculation on the posture of the target, judges whether the target acts abnormally according to the calculation result, and performs corresponding alarm operation when the person acts abnormally.
(3) Pedestrian detection and tracking method
The pedestrian detection and tracking is divided into three parts: firstly, obtaining a moving target area; secondly, establishing a pedestrian detection template; and thirdly, detecting and counting pedestrians. Since the monitoring device is mounted above the escalator, the system identifies the head and shoulders of the person as an identifying feature. The working principle of the algorithm is as follows: firstly, acquiring pedestrian images with obvious head and shoulder combination characteristics and different walking directions by a system as a sample set; then carrying out gray processing on the image to detect the contour of the object; and finally, comparing the matching degrees of the head and the shoulders of the profile, if the matching degree is greater than a threshold value, judging that the pedestrian is a pedestrian, and updating the sample set, thereby optimizing the function of counting the pedestrians.
(4) The object retention detection method adopts a background difference method to carry out foreground detection, firstly a background model is established, then a foreground image is obtained through the difference between a current image and the background image, target extraction is completed, and finally the background model is updated according to a preset strategy. The system adopts a background updating strategy based on a foreground mask to complete object detection, and when the object detection duration is too long, the floor plate object retention detection is judged.
Through the above algorithm, the image data required by the present embodiment can be acquired.
In some embodiments, the system further comprises an information transmission module for transmitting the image data to the image analysis module 2 and for transmitting the analysis result to the central control module 3 by a wired or wireless transmission mode.
Specifically, the information transmission module can adopt wired network transmission or wireless network transmission, and when the wireless network transmission is adopted, a signal receiving and sending device needs to be added to the corresponding module, but the laying of cables can be reduced. The wireless network transmission adopts a 5G mobile communication technology wireless transmission mode, three operator SIM card slots and a signal receiving and transmitting device are reserved in a transmission device of the equipment, and a station monitoring video file and an analysis result receiving file are transmitted through a 5G cellular data signal.
The image analysis module 2 is used for receiving the image data in real time, analyzing and judging the image data and generating an analysis result;
specifically, the image analysis module 2 analyzes and processes the image data of each area, determines whether an abnormal condition exists on an escalator in a certain station, determines and predicts the passenger flow condition of the escalator in the same area in a certain time next, and transmits the corresponding result to the central control module 3 of the corresponding station through the information transmission module.
The central control module 3 is used for receiving the analysis result and sending a control instruction;
and the escalator execution module 4 is used for receiving the control command and controlling the escalator to perform the action matched with the control command.
In some embodiments, the analysis results include passenger abnormal behavior analysis results;
and the image analysis module 2 is used for receiving the image data in real time, and generating an abnormal behavior analysis result of the passenger when the passenger falls down to go backwards or the head and the hands extend out of the hand strap of the escalator through the image data analysis.
Specifically, horizontal coordinates of handrail belts on the left side and the right side of the escalator are set as X1 and X2(X1 is less than X2), coordinates of left positions and right positions of the passenger model are set as X3 and X4(X3 is less than X4), when the image analysis module 2 detects that the passenger position is X4 > X2 or X3 is less than X1, the situation that a head of a user stretches out of the handrail belts is indicated, and a passenger abnormal signal is output; the passenger X3 is more than X2 or X4 is less than X1, which indicates that the passenger climbs the handrail belt and outputs a passenger abnormal signal. After receiving the abnormal signal of the passenger, the central control module 3 can send a control instruction to control the alarm module to work and the like.
When the height and the width of the rectangle for detecting the passenger are respectively H and W, the threshold value of the falling model is A, and when H/W < A, the passenger falls. And after receiving the signal, the central control module 3 stops the escalator.
In some embodiments, the analysis results include passenger abnormal behavior analysis results;
the image analysis module 2 generates an abnormal behavior analysis result of the passenger when the passenger falls down or moves in the reverse direction or the head and the hands extend out of the hand strap of the escalator according to the image data.
The central control module 3 receives the abnormal behavior analysis result of the passenger on the escalator and sends out an alarm instruction or a control instruction of the corresponding escalator running speed.
The escalator execution module 4 receives the alarm instruction or the operation speed control instruction and controls the corresponding voice broadcast and the operation speed of the escalator.
The alarm instruction can be sent out through the voice control module, specifically, the central control module outputs a signal to the voice control module, and the voice control module plays information (for example, do not stretch the head and hands out of the hand strap "); when the situation that passengers stay at the floor plates of the access and the passage are influenced is monitored, the voice control module outputs a signal to play information (for example, the situation that the passengers stay at the access of the escalator and the passage is influenced) is monitored; when the situation that large articles stay on the floor plates of the entrance and the exit to influence passing is monitored, the voice control module outputs a signal to play information (for example, please pay attention to obstacles below the feet of the entrance and the exit of the escalator, and fall down carefully).
In some embodiments, the analysis results include passenger flow density analysis results, escalator speed change analysis results.
Specifically, the passenger flow density on the escalator is classified into unmanned riding, medium-low, medium-high and high levels according to the operation requirements. For the escalator with no passenger at the energy-saving running speed, the image analysis module 2 analyzes that no passenger flow exists in the same area or adjacent areas, and the escalator maintains the energy-saving running speed; when the passenger flow density and direction of the escalator in the same area or adjacent areas are analyzed, and the passenger flow density of the escalator in which the running direction is consistent with the passenger flow direction in the same area is medium or low, the passenger walking speed is analyzed, when the passenger arrives at a certain specific position, the image analysis module 2 sends a signal, the central control module 3 controls the escalator to accelerate to 0.5m/s before the passenger enters the escalator, and the riding comfort of the escalator is improved; when the passenger flow degree of the escalator is about to be changed from unmanned to medium-high or high passenger flow, the running speed of the escalator is adjusted to 0.65m/s from the energy-saving speed in advance; when the passenger flow rate of the escalator is analyzed from medium low to medium high or high, the central control module 3 controls the running speed of the escalator to be adjusted from 0.5m/s to 0.65m/s in advance, and the acceleration is not more than 0.05m/s in the period2Is favorable for quickly evacuating passengersAnd (4) streaming.
More specifically, for an escalator with up-down sections, after a passenger enters a lower escalator, the image analysis module 2 analyzes that when the passenger takes a certain position of the lower escalator, the linkage of the upper escalator is started in advance. Taking the situation of intelligent linkage between the ascending escalator at the upper section and the ascending escalator at the lower section as an example, after the ascending escalator at the lower section takes passengers and arrives at a specific position, the central control module 3 sends a signal to accelerate the ascending escalator at the upper section to a corresponding nominal speed in advance. Meanwhile, if the upper-section ascending escalator has a fault or a dangerous condition, the escalator is decelerated to run or stopped to run, the condition that passengers who arrive at the transfer platform are blocked is monitored and analyzed, the lower-section ascending escalator correspondingly links to perform deceleration running or stopped running, and the dangerous condition caused by the fact that the lower-section ascending escalator continuously runs to cause the large amount of accumulation of the passengers on the transfer platform is avoided.
In some embodiments, the system further comprises a display module, configured to display a video corresponding to the passenger abnormality analysis result when the central control module 3 receives the passenger abnormality analysis result.
