Description

Technical Field

[0001] The present invention relates to the technical field of elevator control systems, and in particular to a safety intelligent protection system and method based on a car-type elevator. Background Art

[0002] Elevators are commonly found in public places and are used to provide continuous riding services. The most common elevators are escalators and elevators, with elevators mainly being cabin-type elevators. During use, a camera is installed in the elevator cabin, through which security personnel can learn about the situation in the elevator cabin. At the same time, an emergency button is installed in the elevator cabin, and users in the elevator cabin can contact security personnel by actively triggering the emergency button, thereby ensuring the safety of elevator users. However, in actual use, there are multiple elevators and a corresponding number of cameras. If each elevator is equipped with a display and a security guard, it will undoubtedly require a large amount of equipment, a large site and labor costs. Therefore, in the prior art, images captured by multiple elevator cameras are often played in turn on the display, which can not only observe the situation in each elevator cabin, but also reduce equipment, site requirements and labor costs.

[0003] In the prior art, abnormal behaviors in elevator cars can only be observed by security personnel, or triggered by users in the elevator car through emergency buttons, but the images collected by multiple elevator cameras are played in a carousel, making it difficult for security personnel to detect abnormal behaviors in time. Therefore, there is an urgent need in the prior art for a security intelligent protection system that can actively identify abnormal behaviors in elevator cars and improve safety. Summary of the invention

[0004] One of the purposes of the present invention is to provide a safety intelligent protection system based on a car-type elevator, which can actively identify abnormal behaviors in the elevator car and improve safety.

[0005] The basic scheme 1 provided by the present invention is a safety intelligent protection system based on a car-type elevator, comprising a monitoring module arranged in the elevator car and a display module arranged in the security room, wherein the monitoring module is used to collect elevator images and upload them, and the display module is preset with a playback frequency corresponding to each monitoring module, and the display module is used to display the elevator images collected by each monitoring module in turn according to the playback frequency; and further comprising: The monitoring server is used to determine whether a woman is walking alone in the elevator car and whether there is a person of the opposite sex in the elevator car based on the elevator image. When it is determined that there is a person of the opposite sex in the elevator car and the woman is walking alone, the playing frequency of the monitoring module corresponding to the elevator image is increased; It is also used to determine if there is a person of the opposite sex in the elevator car and the woman is walking alone. When the woman leaves, it is determined based on the elevator image whether other people in the elevator car have abnormal behavior. If it is determined that other people have abnormal behavior, the person with abnormal behavior will be recorded as an abnormal person. It is also used to determine whether there is an abnormal person in the elevator car based on the elevator image. When it is determined that there is an abnormal person, the playback frequency of the monitoring module corresponding to the elevator image is increased.

[0006] Further, the monitoring server includes: An image recognition module is used to identify the gender of people and the corresponding number of people in the elevator image. The gender of the people includes female and male; The opposite sex determination module is used to determine whether there are opposite sex people in the elevator car when the gender of the people identified by the elevator image is female or male.

[0007] Furthermore, the monitoring server also includes: A lone person determination module is used to determine that a woman is walking alone in the elevator car when the gender of the person identified in the elevator image is female and the number of the corresponding person is 1; It is also used to determine whether a woman has an intimate relationship with other people in the elevator car when the genders of the people identified in the elevator image are female and male, and the number of female people is 1. When it is determined that there is no intimate relationship, it is determined that the woman in the elevator car is alone.

[0008] Furthermore, the lone travel determination module is preset with a spatial model and a behavioral model. The spatial model is used to input continuous elevator images, analyze the intimacy of the people in the elevator car according to the changes in the spatial distance of the people in the elevator image, and output the spatial intimacy between the woman and other people in the elevator car; the behavioral model is used to input continuous elevator images, analyze the behavioral correlation of the people in the elevator car according to the behavior of the people in the elevator image, and output the behavioral intimacy between the woman and other people in the elevator car; The lone travel determination module is also used to obtain the spatial intimacy output by the spatial model based on the elevator image and the behavioral intimacy output by the behavioral model based on the elevator image, and to determine whether the woman has an intimate relationship with other people in the elevator car based on the spatial intimacy and the behavioral intimacy.

[0009] Furthermore, the image recognition module is also used to determine that a woman has left the elevator car when the gender of the people identified by the elevator image changes from female and male to male; The monitoring server also includes: The behavior determination module is used to identify the status of the elevator door and elevator buttons when the opposite sex determination module determines that there is a person of the opposite sex in the elevator car, and the lone travel determination module determines that a woman is walking alone in the elevator car, and the image recognition module determines that the woman has left the elevator car; It is also used to determine whether other people in the elevator car have abnormal behavior when the elevator door opening button is triggered and no one enters or exits the elevator door; It is also used to determine whether other people in the elevator car have abnormal behavior when the elevator door opening button is triggered and someone leans out of the elevator door; It is also used to determine abnormal behavior of other people in the elevator car when the elevator door is blocked for a long time.

[0010] Furthermore, the monitoring server also includes: The abnormal person marking module is used to mark the person who triggers the elevator door opening button or blocks the elevator door in the elevator car according to the elevator image when the behavior determination module determines that other people in the elevator car have abnormal behavior, and record the corresponding person as an abnormal person.

[0011] Furthermore, the monitoring server is also used to record abnormal persons and store the female leaving the elevator car in association; It is also used to determine whether other people in the elevator car are abnormal persons based on the elevator image when it is determined that there is a person of the opposite sex in the elevator car and the woman is traveling alone. When it is determined that there is an abnormal person, it is determined whether the woman is stored in association with the abnormal person. If so, the display module is controlled to continuously play the corresponding elevator image.

[0012] Furthermore, the abnormal person marking module is also used to record the facial information and body information of the abnormal person when the corresponding person is an abnormal person; it is also used to associate and store the facial information of the woman leaving the elevator car when recording the abnormal person.

[0013] Beneficial effects of basic solution 1: The monitoring module is a camera installed in the existing elevator. The elevator images collected by the monitoring module are usually sent to the display module in the security room for display. The display module is a display installed in the security room. The security personnel in the security room can know the situation in each elevator car through the display module.

[0014] The monitoring server is set up to realize the recognition and analysis of elevator images, so as to know whether there are potential risks for women riding alone in the elevator, and mark the potential risks. When the same situation occurs next time, more attention will be paid to women riding alone in the elevator, and risks will be discovered and controlled in time to improve safety. For example, when a criminal follows a woman walking alone, he will ride the elevator alone with the woman, and when the woman leaves the elevator, he will observe the direction in which the woman leaves, obtain information such as the woman's living environment, and identify and mark such criminals through the monitoring server. When the criminal follows the same woman again, the criminal's behavior will be observed. When the criminal follows the woman out of the elevator, it can be discovered in time, and the woman, property or security personnel can be notified to go there, so as to ensure the safety of the residents. This solution improves the accuracy of identifying people with abnormal behavior, and can timely discover potential risks through elevator images to improve safety.

[0015] The image recognition module is set to identify the gender and corresponding number of people in the elevator car, so as to facilitate the subsequent judgment of whether the opposite sex is in the same elevator car and whether it is a woman alone. The opposite sex determination module is set to determine whether the opposite sex is in the same elevator car based on the recognition result of the image recognition module, so as to facilitate the subsequent judgment of whether to identify abnormal behavior. The lone determination module is set to determine whether the woman is alone in the elevator and whether the woman is traveling with others based on the recognition result of the image recognition module and the behavior analysis of women and other people in the elevator car. After excluding the above two situations, it can be known that there is a woman and multiple men in the elevator car, and the women and men do not know each other. At this time, the frequency of playing the elevator image of the elevator car is increased to increase the attention to the elevator car.

[0016] When judging whether a woman is traveling with someone else, a comprehensive judgment is made based on the body movements and spatial distance between the woman and the other people. The spatial model makes a preliminary judgment on the relationship between the two people based on the spatial distance between the woman and the other people. In the absence of external interference, if the two people are not familiar with each other, they will be at a farther distance in the elevator car (for example, the two occupy two corners of the elevator car). If the two people are familiar with each other, they will be at a closer distance (for example, the two stand next to each other). The behavioral model makes a preliminary judgment on the relationship between the two people based on the behavior between the woman and the other people. For example, actions such as holding hands must mean that the two people are familiar with each other. The lone travel determination module makes a preliminary judgment on the relationship between the woman and other people in the elevator car based on the spatial model and the behavioral model, and then combines the two to further determine the relationship, thereby improving the recognition accuracy of the lone travel determination module.

[0017] The setting of the behavior determination module identifies the behavior of the other people in the elevator car after the woman leaves the elevator car, and determines whether there is any abnormal behavior, such as observing the direction in which the woman leaves, so as to determine whether the people in the elevator car will pose a potential risk to the woman leaving the elevator car. The setting of the abnormal person marking module marks and records the people whose abnormal behavior is determined in the behavior determination module. When recording, the women observed by the abnormal person are stored in association, that is, the abnormal person poses a potential risk to the associated women. The next time, only when the two are in the same elevator car, the elevator image of the elevator car is played fixedly to increase the attention to the elevator car and improve safety.

[0018] A second object of the present invention is to provide a safe and intelligent protection method based on a car-type elevator.

[0019] The present invention provides basic solution 2: a safety intelligent protection method based on a car-type elevator, using the above-mentioned safety intelligent protection system based on a car-type elevator.

[0020] Further, the following are included: Obtain and upload elevator images collected by a monitoring module in the elevator car, where there are multiple monitoring modules; Judging whether a woman is walking alone in the elevator car and whether there is a person of the opposite sex in the elevator car according to the elevator image, when it is determined that there is a person of the opposite sex in the elevator car and the woman is walking alone, increasing the playing frequency of the preset elevator image; When it is determined that there is a person of the opposite sex in the elevator car and the woman is traveling alone, it is determined whether the other person in the elevator car is an abnormal person based on the elevator image. When it is determined that there is an abnormal person, it is determined whether the woman is stored in association with the abnormal person. If so, the corresponding elevator image is continuously played; After determining that there is a person of the opposite sex in the elevator car and the woman is walking alone, determine whether other people in the elevator car have abnormal behavior when the woman leaves based on the elevator image. If it is determined that other people have abnormal behavior, the person with abnormal behavior is recorded as an abnormal person; when recording an abnormal person, the woman who left the elevator car is associated and stored; When it is determined that there is no person of the opposite sex or no woman walking alone in the elevator car, it is determined whether there is an abnormal person in the elevator car according to the elevator image. When it is determined that there is an abnormal person, the playback frequency of the preset elevator image is increased; The elevator images collected by multiple monitoring modules are played in turn according to the playback frequency.

[0021] Beneficial effects of basic solution 2: The elevator image is collected by the camera installed in the existing elevator car. The collected elevator image is usually sent to the display module in the security room for display. The display module is a display installed in the security room. It plays the elevator image corresponding to each elevator car in turn. The security personnel in the security room can know the situation in each elevator car through the display module. This solution identifies and analyzes the elevator image to find out whether there is a potential risk for women riding alone in the elevator, and marks the potential risk. The next time the same situation occurs, more attention will be paid to women riding alone in the elevator, and risks will be discovered and controlled in time. This solution improves the accuracy of identifying people with abnormal behavior, and can detect potential risks in time through elevator images, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 The present invention is a logic block diagram of an embodiment of a safety intelligent protection system based on a car-type elevator. DETAILED DESCRIPTION

[0023] The following is further described in detail through specific implementation methods: Example The intelligent safety protection system based on the car-type elevator includes a monitoring module in the elevator car and a display module in the security room. The monitoring module is used to collect elevator images and upload them. The display module is preset with the corresponding playback frequency of each monitoring module. The display module is used to display the elevator images collected by each monitoring module in turn according to the playback frequency. It also includes: The monitoring server is used to determine whether a woman in the elevator car is walking alone and whether there is a person of the opposite sex in the elevator car based on the elevator image. When it is determined that there is a person of the opposite sex in the elevator car and the woman is walking alone, the playback frequency of the monitoring module corresponding to the elevator image is increased.

[0024] It is also used to determine whether other people in the elevator car are abnormal persons based on the elevator image when it is determined that there is a person of the opposite sex in the elevator car and the woman is traveling alone. When it is determined that there is an abnormal person, it is determined whether the woman is stored in association with the abnormal person. If so, the display module is controlled to continuously play the corresponding elevator image.

[0025] It is also used to determine if there is a person of the opposite sex in the elevator car and if the woman is alone, and to judge whether other people in the elevator car have abnormal behavior when the woman leaves based on the elevator image. When it is determined that other people have abnormal behavior, the person with abnormal behavior is recorded as an abnormal person. It is also used to associate and store the woman who left the elevator car when recording abnormal persons.

[0026] It is also used to determine whether there is an abnormal person in the elevator car based on the elevator image. When it is determined that there is an abnormal person, the playback frequency of the monitoring module corresponding to the elevator image is increased.

[0027] Specific: As attached Figure 1 As shown, the monitoring server includes an image recognition module, a heterosexual determination module, a lone travel determination module, a behavior determination module, an abnormal person marking module, an abnormal determination module, a playback adjustment module and a database.

[0028] The monitoring module is set in the elevator car and is used to collect elevator images of the elevator car. The continuously collected elevator images constitute the monitoring video. The elevator image contains the elevator door, elevator buttons and people in the elevator car. The elevator image also contains the face information of the people, and the monitoring video contains the body information of the people. The database is used to store elevator images.

[0029] The display module is set in the security room, and the security personnel in the security room can view the elevator images corresponding to different elevator cars through the display module. Elevators are usually used in parks, communities, schools and other places, and there are many of them. Therefore, the display module plays the elevator images collected by each monitoring module in turn according to the preset playback frequency. During daily use, the playback frequency and playback duration of each monitoring module are the same. For example, the elevator image collected by monitoring module A is played for N seconds, and the elevator image collected by monitoring module B is played for N seconds. After the elevator images collected by all monitoring modules are played for N seconds, the elevator image collected by monitoring module A is replayed for N seconds. N is the playback duration set in advance. In this way, the elevator images collected by each monitoring module are played in turn to realize the monitoring and management of each elevator.

[0030] The monitoring module is a camera installed in the existing elevator. The elevator images collected by the monitoring module are usually sent to the display module in the security room for display. The display module is a display installed in the security room. The security personnel in the security room can know the situation in each elevator car through the display module.

[0031] The image recognition module is used to identify the gender of the people in the elevator image and the corresponding number of people. The gender of the people includes female and male, and the number of people corresponding to the gender of the people is a natural number. For example, if there are three men and two women in the elevator car, the gender of the people identified by the image recognition module is male and female, the number of males corresponding to the number of people is three, and the number of females corresponding to the number of people is two. The elevator image is a continuously collected image, and the image recognition module is also used to determine that the woman has left the elevator car when the gender of the people identified by the elevator image changes from female and male to male. For example, in the continuous elevator images, the previous elevator image identifies two men and one woman, and the next elevator image identifies two men, which means that a woman has left the elevator car during this process. At this time, the gender of the people identified according to the elevator image changes from female and male to male.

[0032] The opposite sex determination module is used to determine the presence of opposite sex in the elevator car when the gender of the people identified in the elevator image is female and male, that is, there are male and female in the elevator car at this time.

[0033] The lone person determination module is used to determine that a woman is walking alone in the elevator car when the gender of the crowd identified in the elevator image is female and the corresponding crowd number is 1. At this time, there is only one woman in the elevator car.

[0034] The lone travel determination module is also used to determine whether the woman has an intimate relationship with other people in the elevator car when the gender of the people identified in the elevator image is female and male, and the number of female people is 1 (at this time, there is one woman and multiple men in the elevator car, but there may be women and men traveling together, so the relationship between the woman and the other men needs to be analyzed). If it is determined that there is no intimate relationship, it is determined that the woman in the elevator car is alone. Specifically: The lone travel determination module is preset with a spatial model and a behavioral model. The spatial model is used to input continuous elevator images, analyze the intimacy of the crowd in the elevator car according to the changes in the spatial distance of the crowd in the elevator image, and output the spatial intimacy between the woman and other people in the elevator car. The spatial distance between the woman and the other men is analyzed through continuous elevator images, i.e., surveillance videos. For example, the spatial distance between people represents the relationship between the two people to a certain extent. When the spatial distance between the two people is less than the intimate distance, it represents that the two people have an intimate relationship, such as lovers and good friends; when the spatial distance between the two people is greater than the intimate distance and less than the personal distance, it represents that the two people have a familiar relationship, such as friends and acquaintances, and when the spatial distance between the two people is greater than the personal distance, it more represents that the two people are unfamiliar, or even strangers. Therefore, the spatial model analyzes the intimacy between the woman and the other men in the elevator car based on the changes in the spatial distance between the woman and the other men, and generates spatial intimacy.

[0035] The behavior model is used to input continuous elevator images, analyze the behavioral relevance of the crowd in the elevator car based on the crowd behavior in the elevator image, and output the behavioral intimacy between the female and other people in the elevator car. When the female in the elevator car is walking with the other males, some interactive behaviors may occur, such as holding hands, arm in arm, and leaning on each other. The behavior model analyzes whether the female and the other males have interactive behaviors in the elevator car, and what kind of interactive behaviors they have, judges the intimacy between the two, and generates behavioral intimacy.

[0036] The lone travel determination module is also used to obtain the spatial intimacy output by the spatial model based on the elevator image and the behavioral intimacy output by the behavioral model based on the elevator image, and to determine whether the woman has an intimate relationship with other people in the elevator car based on the spatial intimacy and behavioral intimacy. The spatial intimacy and behavioral intimacy are expressed in percentages, and the lone travel determination module is preset with an intimacy threshold. The lone travel determination module is used to determine whether the spatial intimacy or behavioral intimacy is greater than the intimacy threshold. When the spatial intimacy or behavioral intimacy is greater than the intimacy threshold, it is determined that the woman has an intimate relationship with other people in the elevator car; otherwise, the total intimacy value is calculated according to the following formula: In the formula, S is the spatial intimacy, B is the behavioral intimacy, and L is the total intimacy value calculated according to the above formula.

[0037] The lone travel determination module is also used to determine whether the total intimacy value is greater than the intimacy threshold. When the total intimacy value is greater than the intimacy threshold, it is determined that the woman has an intimate relationship with other people in the elevator car. Otherwise, it does not exist. It is determined one by one whether the woman in the elevator car has an intimate relationship with the other men. When the woman in the elevator car does not have an intimate relationship with the other men, it is considered that the woman is alone.

[0038] The behavior determination module is used to identify the status of the elevator door and elevator buttons when the opposite sex determination module determines that there is an opposite sex in the elevator car, and the lone travel determination module determines that a woman is walking alone in the elevator car, and the image recognition module determines that the woman has left the elevator car. The status of the elevator door includes the elevator door being open, the elevator door being closed, and the elevator door being blocked, and the status of the elevator button includes the triggering of each button.

[0039] The behavior determination module is also used to determine that other people in the elevator car have abnormal behavior when the elevator door opening key is triggered and no one enters or exits the elevator door. Specifically, when the elevator door opening key is triggered, the elevator door opens, and no one enters or exits according to the elevator image recognition, it is determined that other people in the elevator car have abnormal behavior. At this time, the person who triggered the elevator door opening key is the person with abnormal behavior.

[0040] The behavior determination module is also used to determine that other people in the elevator car have abnormal behavior when the elevator door opening key is triggered and someone leans out of the elevator door. Specifically, when the elevator door opening key is triggered, the elevator door is blocked, and someone leans out according to the elevator image recognition, it is determined that other people in the elevator car have abnormal behavior. At this time, the person who triggered the elevator door opening key and blocked the elevator door is the person with abnormal behavior.

[0041] The behavior determination module is also used to determine if other people in the elevator car have abnormal behavior when the elevator door is blocked for a long time. Specifically, when none of the elevator buttons are triggered, the elevator door is blocked, and the blocking period exceeds the preset stop threshold, it is determined that other people in the elevator car have abnormal behavior. At this time, the person blocking the elevator door is a person with abnormal behavior. The stop threshold is the length of time the elevator door is open on a certain floor under normal conditions, which is preset in advance by the developer.

[0042] The abnormal person marking module is used to mark the person who triggers the elevator door opening button or blocks the elevator door in the elevator car according to the elevator image when the behavior determination module determines that other people in the elevator car have abnormal behavior, and record the corresponding person as an abnormal person. Specifically: when the elevator door opening button is triggered and no one enters or exits the elevator door, the person who triggers the elevator door opening button is recorded as an abnormal person; when the elevator door opening button is triggered and someone leans out of the elevator door, the person who triggers the elevator door opening button and blocks the elevator door is recorded as an abnormal person; when the elevator door is blocked for a long time, the person who blocks the elevator door is recorded as an abnormal person.

[0043] The abnormal person marking module is also used to record the facial information and body information of the abnormal person when the corresponding person is an abnormal person; it is also used to store the facial information of the woman leaving the elevator car in association with the abnormal person. The facial information can be obtained based on the analysis of the elevator image, and the body information can be obtained based on the analysis of the surveillance video. The facial information and body information of the abnormal person, as well as the associated stored facial information of the woman, are all stored in the database.

[0044] The abnormality determination module is used for the opposite sex determination module to determine the presence of the opposite sex in the elevator car, and when the lone determination module determines that a woman is walking alone in the elevator car, the elevator image and the abnormal persons stored in the database are matched to determine whether other people in the elevator car are abnormal persons. When there is a match, it is determined that an abnormal person exists. The abnormality determination module is also used to determine whether the woman is stored in association with the abnormal person. If so, a fixed playback signal is generated. That is, when there is a woman and multiple men in the elevator car, and the woman has no relationship with the other men, the abnormal person is in the same elevator car with the woman associated with her again. At this time, it is determined that the man with abnormal behavior is in the same elevator with the lone woman who is observed abnormally for many times, and a fixed playback signal is generated to play the elevator image corresponding to the elevator car.

[0045] The image recognition module is also used to determine whether there is an abnormal person in the elevator car based on the elevator image. Specifically, the elevator image is matched with abnormal persons stored in the database. When there is a match, it is determined that there is an abnormal person.

[0046] The playback adjustment module is used to increase the playback frequency of the monitoring module corresponding to the elevator image when the opposite sex determination module determines that there is an opposite sex in the elevator car, and the lone travel determination module determines that a woman is walking alone in the elevator car. The playback adjustment module is also used to increase the playback frequency of the monitoring module corresponding to the elevator image when the image recognition module determines that there is an abnormal person. For example, in a unit of time, the playback frequency of the corresponding monitoring module is increased to twice that of the remaining monitoring modules, or the playback duration of the corresponding monitoring module is increased to twice that of the remaining monitoring modules. By increasing the playback frequency and playback duration of the monitoring module, the behavior monitoring of abnormal people in the elevator car is increased. The playback adjustment module is also used to control the display module to continuously play the corresponding elevator image when the abnormal determination module generates a fixed playback signal. The setting of the playback adjustment module changes the playback frequency or duration of the display module playing different elevator images, thereby increasing the attention to the corresponding elevator car.

[0047] The monitoring server is set up to realize the recognition and analysis of elevator images, so as to know whether there are potential risks for women riding alone in the elevator, and mark the potential risks. When the same situation occurs next time, more attention will be paid to women riding alone in the elevator, and risks will be discovered and controlled in time to improve safety. For example, when a criminal follows a woman walking alone, he will ride the elevator alone with the woman, and when the woman leaves the elevator, he will observe the direction in which the woman leaves, obtain information such as the woman's living environment, and identify and mark such criminals through the monitoring server. When the criminal follows the same woman again, the criminal's behavior will be observed. When the criminal follows the woman out of the elevator, it can be discovered in time, and the woman, property or security personnel can be notified to go there, so as to ensure the safety of the residents. This solution improves the accuracy of identifying people with abnormal behavior, and can timely discover potential risks through elevator images to improve safety.

[0048] The intelligent safety protection method based on the car-type elevator uses the intelligent safety protection system based on the car-type elevator. It includes the following contents: S1: Acquire and upload elevator images collected by a monitoring module in the elevator car. There are multiple monitoring modules, and the continuously collected elevator images form a monitoring video.

[0049] S2: Determine whether the woman in the elevator car is alone and whether there is the opposite sex in the elevator car based on the elevator image.

[0050] S301: When it is determined that there is a person of the opposite sex in the elevator car and the woman is traveling alone, the playback frequency of the preset elevator image is increased.

[0051] S302: When it is determined that there is a person of the opposite sex in the elevator car and the woman is traveling alone, whether the other person in the elevator car is an abnormal person is determined based on the elevator image; when it is determined that there is an abnormal person, whether the woman is stored in association with the abnormal person, and if so, the corresponding elevator image is continuously played; S303: When it is determined that there is no person of the opposite sex or no woman walking alone in the elevator car, determine whether there is any abnormal person in the elevator car based on the elevator image. When it is determined that there is an abnormal person, increase the playback frequency of the preset elevator image.

[0052] S4: After determining that there is a person of the opposite sex in the elevator car and that the woman is traveling alone, determine whether other people in the elevator car have behaved abnormally when the woman left based on the elevator image. If it is determined that other people have behaved abnormally, the person with abnormal behavior is recorded as an abnormal person; when recording an abnormal person, the woman who left the elevator car is associated and stored.

[0053] S5: Play the elevator images collected by multiple monitoring modules in turn according to the playing frequency.
