CZ307289B6 - A method of prevention of dangerous situations when gathering persons at mass events, in means of transport, using the emotional curve of people - Google Patents

Abstract

A method of prevention of dangerous situations when gathering persons at mass events, in means of transport, using the emotional curve of people, allows obtaining immediate information about the emotional status of a group of people in a monitored environment and, based on this data, predicting the emergence of a crisis situation and taking appropriate organizational measures. The method allows gaining control over the monitored area, even when the emotions of the group of people in this area are rising, thus preventing the occurrence of a dangerous situation.

Description

Method for preventing dangerous situations in gathering people at mass events, in vehicles, using the emotional curve of people

Technical field

The present invention relates to the prevention of emotionally unstable situations in a multi-person assembly using human voice and emotional curve analysis.

BACKGROUND OF THE INVENTION

At present, monitoring of dangerous situations related to human behavior is in many cases carried out visually or by the use of technical means, eg by means of camera systems of different levels. The camera is placed in a potentially hazardous area and the signal from it is transmitted to the central control panel of its administrator, eg police, city police, steward of the vehicle. The CCTV operator then monitors the designated area on the monitors. In the event of a crisis situation, the camera operator sends a patrol to the monitored location, which solves the situation. In this case, we are talking about security cameras, the evaluation of the situation depends on the eyesight and experience of their operation.

Monitoring and evaluation of human emotions is then dealt with in the patent literature, for example, the publication entitled WO 9931653 entitled "Aparatus and methods for detecting emotions", which describes a device for detecting an individual's emotional state based on voice analysis. This type of device is used eg in call centers. Based on the voice analysis, during the interview with the client, the program signals the occurrence of a risk situation during the call, the situation is notified to the center supervisor, who enters the call and calms the situation. From the above it is clear that this method is used in individual cases.

SUMMARY OF THE INVENTION

The subject of the application is a method used to prevent dangerous situations in a large number of gathered persons, eg in mass events and in vehicles, using the knowledge gained from the so-called emotional curve of people. The proposed method makes it possible to predict risk behavior of a larger group of people and thus allows to calm the situation before the crisis in the group. If the standard behavior of a group of people is exceeded (the standard behavior of a group of people is defined by the level of sensitivity of the reference emotional curve), ie after detecting an increase in emotions in the monitored group, it is possible to prevent or directly resolve the conflict.

The method is based on knowledge of human voice analysis and people's emotional curve, on the basis of which it is possible to evaluate human behavior. In the proposed method, the reference emotional curve, which is stored in a memory block (device containing memory - memory card, memory disk, etc.) is set as a standard and is further designed for further evaluation of emotional state of a group of people in monitored space. needs for sections. The reference emotional curve is compared with the measured voice levels of people from the monitored area, in the so-called comparison block, which represents a computing device.

By comparing these data we get information on the state of emotions of a group of people in the monitored area. When a certain level of reference emotional curve is exceeded in any of the sections, this condition is signaled on the display device, e.g., the screen, and the idle state information is recorded as well as information about the specific location / section of the violation. The information displayed is also used to determine the organizational measure - according to the application of the method - which responds to the situation and is intended to prevent a conflict situation. Organizational

The measures usually consist of calming the situation, eg with psychologists, so-called anti-conflict teams, or security forces.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

In the means of transport (aircraft, train) the passenger compartment is monitored and divided into sections. Audio information is used to record audio information - the level of passengers' voice from each section of the monitored area, which is a vehicle, such as a wagon. The measured voice level is compared in the computing device with the reference voice curve level stored in the memory block. The limit of reference voice curve level differs according to the type of monitored environment (plane, train, stadium). If the current measurement state in the monitored area shows significant deviations from the specified level of the reference curve, this fact is recorded in the memory of the display device, which informs the crew of the vehicle that the set state has been exceeded. At the same time, in the section where this exceeds, video sensors are immediately turned on to document the situation.

Example 2

During the sport match, the stadium space is monitored - especially the section representing the grandstand, designed for the fans of the visiting team. The voice information sensed by the audio sensors is compared in the computing device to the level of the reference voice curve located in the memory block. This level varies depending on the type of environment being monitored (quiet part of the stadium - home, restless part - guests). If the current state in the monitored area shows significant deviations from the level of the reference curve, this fact is recorded in the memory and displayed on the display, which informs the organizer about exceeding the set state, and they will solve the situation. At the same time, in the section, for fans of the visiting team of the monitored area of the stadium, where this exceeds, video sensors are immediately switched on to document the situation.

Example 3

The interior of the prison is designated as a monitored area and it identifies the risk parts of the section. During the period determined by the prison management as risky, audio information - the level of prisoners' votes from individual sections of the monitored area of the prison - is recorded by audio sensors. The voice information is compared in the computing device with the level of the reference voice curve stored in the memory block. This level of reference curve varies according to the type of environment being monitored (stadium, aircraft). If the current state of the emotional voice curve in the monitored area shows significant deviations from the level of the reference curve, this fact is recorded in the memory and displayed on the display, which informs the prison guard about exceeding the set state, and they will solve the situation. At the same time, in the section of the monitored area of the prison where this violation occurs, video sensors are immediately turned on to document the situation.

Industrial applicability

The solution can be used for example in the field of transport, sports, medical facilities, security events, as well as organizing public events, etc.

Claims (1)

PATENT CLAIMS 1. A method for preventing dangerous situations in the gathering of persons at mass events, means of transport, using the human emotional curve and the voice analysis carried out in the computing device, characterized in that the monitored area is divided into sections, audio sensors are located in individual sections; video sensors, audio sensors scan the monitored area and send instantaneous levels of people's voices to a computing device where they are compared to a defined reference emotional curve stored in a memory block if the measured human voice level data is higher than the defined reference emotional curve data on the display device the section in which this violation occurred is automatically signaled and at the same time the video cameras are automatically started to document the situation in the section.
