[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a technical solution for a method for dynamic detection of traffic violation behaviors based on video frame extraction technology:

[0028] Embodiment 1:

[0029] like Figure 1 As shown, the dynamic detection method of this technical solution mainly includes:

[0030] Step 1: Preprocessing the collection of data on the outside of the factory, specifically, entering the standard state at various angles at the entrance of the factory, that is, the standard dress state of protective measures for workers entering the factory, and entering it into the background system;

[0031] Step 2: The positioning device is distributed and installed at the factory door. The staff inside the factory assembles it on their protective clothing in real time. For the staff and equipment that temporarily enter the factory, they are operated in a temporary assembly manner and are promptly recovered when leaving the work area. The positioning device is specifically a GPS positioning device, which accurately locates the remote target through the satellite positioning terminal. More specifically, it can also be more simply through the coverage of the wireless network in the factory area and the connection of the wireless network to achieve real-time positioning, and it is promptly removed after leaving the factory area;

[0032] Step 3: Install the security monitoring system at a high altitude in the factory, at a height and angle that can capture all situations in the factory. Install it on each running equipment, and try to install it at a high place on the equipment, and install it from a bird's-eye view;

[0033] Step 4: Install the alarm device. The alarm device mainly consists of flashing lights and loudspeakers. The specific installation locations are as follows: it is installed in the central location of the factory, the entrance and exit locations, the emergency evacuation location, and on each device.

[0034] Step 5: The factory is put into use and automatically detects violations.

[0035] Among them, the dynamic detection method also includes a detection system, which specifically includes a signal data acquisition system, a signal transceiver system and a background processing system. The data acquisition system is mainly the security monitoring device in step three, and the signal transceiver system is mainly installed on the security monitoring device, the alarm device and the background processing system.

[0036] Among them, the background processing system mainly includes a central processing unit and a screen display unit. The display unit here is mainly divided into two parts. One part is installed in the security room for real-time viewing by security personnel in the factory area. Security personnel can use real-time screen information and the cooperation of the violation detection system. When a violation occurs, they can quickly and accurately understand the real-time status of the violation and whether the violation is serious, and then stop it in time or provide timely rescue. The other part is placed in the supervision room for supervisors to view in real time the status of vehicles in the factory area, equipment in the workshop and staff. The screen display unit can use the most common electronic display at present, and of course, split-screen processing is required to ensure that the images transmitted back from different areas can be displayed. The central processing unit is mainly used to process the signal data received and to be sent. The screen display unit is mainly a display device used to display the real-time status in the factory area.

[0037] Among them, the central processing unit mainly includes a data storage unit, a database unit and a judgment and comparison unit.

[0038] In this embodiment, the detection of illegal behaviors is mainly aimed at the external conditions of the buildings in the factory area, such as Figure 2 As shown, first of all, there is the detection process of the staff in the plant area. When the staff is about to enter the working area of ​​the thermal power plant, especially when they are about to enter the plant, the security monitoring equipment samples the staff entering the thermal power plant one by one, and compares the sampled image information with the standard protective clothing status, such as whether they are wearing a safety helmet, whether they are wearing normal protective clothing, etc. When no violation is found, no processing is done, but simply the information of the personnel entering the working plant of the thermal power plant is recorded and stored;

[0039] When comparing information, if a violation occurs, an immediate response is made, that is, a signal is sent to the flashing light and loudspeaker at the factory door through the signal transceiver module, so that the flashing light flashes and a voice broadcast is used to warn, thereby helping the staff who are about to enter the factory to correct the violation in time to ensure the safety of the thermal power plant during normal operation;

[0040] For temporary personnel from outside, the above-mentioned related tests are also required, especially for those who are not plant staff. This part of the test is more stringent because the working area of ​​a thermal power plant is relatively dangerous and requires strict compliance with relevant rules and regulations to ensure safety.

[0041] Once a violation occurs, the location where the violation occurs and the nearest alarm device will be promptly notified based on the location displayed by the background system. The signal will also be sent to the security room to inform security personnel and people at and near the violation location. Flashing lights and sound alarms will be used to remind people of the violation and they can make corrections or provide reminders and help. At the same time, flashing lights near the violation can serve as a good reminder for people nearby to stay away from dangerous areas, while also avoiding congestion and secondary accidents.

[0042] Embodiment 2:

[0043] like Figure 3 As shown, the dynamic detection method of this technical solution mainly includes:

[0044] Step 1: Pre-collect and input the situation of the workshop.

[0045] Step 2: Install security monitoring devices in the production area to monitor the production situation in the workshop in real time;

[0046] Step 3: Install a positioning device and an alarm device on each operating device;

[0047] Step 4: The factory is put into use to automatically detect violations. The specific detection is mainly through video frame extraction technology to compare and judge the behavior of staff, the way of operating equipment, the use of protective measures and the operating status of equipment.

[0048] Among them, the supervision content in step two mainly includes information supervision of the working status of staff and equipment in the workshop.

[0049] Among them, the data entered in step one mainly includes equipment operation regulations and standard status of operators. The standard status of operators mainly includes their own protective measures and status, and also includes the normal operating status information of each equipment employee.

[0050] In this embodiment, Figure 4 As shown, the specific process of the dynamic detection method of the present technical solution is as follows: first, the status information of the equipment and personnel in the workshop is collected through the security monitoring equipment, and the collected information is sent to the background system. Then, the background system first displays the collected information in real time through the screen display device. Secondly, the collected information is compared with the normal status in the database at intervals to determine whether there is any violation. Specifically, for the operator himself, the most important thing is that the protective measures he takes when working are in compliance with the specifications; secondly, the security monitoring equipment on each device in the thermal power plant must correspond to the operating rules of the corresponding equipment in the system. During normal working hours, each security monitoring device collects information on the staff's operating methods in real time until the operation is completed. Once the equipment is not operated in accordance with the operating rules, a signal is immediately sent to the corresponding location to warn the operator to correct the behavior;

[0051] The top-down layout design of security monitoring equipment can check in real time whether there are people in the surrounding dangerous areas when collecting information about the equipment and its vicinity, and promptly remind people near the place where the violation occurred to stay away from the dangerous area. It can also check in real time whether the operator is operating the equipment in the designated safe area. Once the comparison finds improper operation, the nearest alarm device will flash the light and voice alarm. On the other hand, it can better detect the equipment operation status and the actions of employees operating the equipment. By comparing and judging with the standard operation status information, once a violation is found, a flashing light and voice alarm will be used at the equipment location to remind the violation and correct it in time.

[0052] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
