Abstract
Description
Technical Field
[0001] The present invention relates to the field of safety protection technology, and in particular to a safety protection monitoring and management system applied to industrial plants. Background Art
[0002] In modern industrial production, enterprises have put forward higher and higher requirements for the safety management of the factory area. In order to protect the safety of the factory area, the conventional practice is to set up an access control system at the entrance of the factory area to authenticate the identity of the people entering and leaving through card swiping, password or biometric recognition. However, this access control system based on a fixed location has certain limitations and cannot fully prevent the intrusion of intentional outsiders. Once an outsider bypasses the access control system in some way or enters the factory area with the assistance of authorized personnel, the access control system loses its monitoring function.
[0003] In order to solve the above problems, the existing technology usually adopts the method of installing cameras to monitor the interior of the factory in real time. These cameras can be connected to the central monitoring system, and the image data can be analyzed in real time through video analysis software. Once abnormal behavior or unauthorized entry is detected, a security alarm can be triggered. Although this method enhances internal monitoring to a certain extent, it still has the problems of insufficient flexibility and high false alarm rate. Especially when the factory needs external technical service personnel to enter for equipment maintenance and other activities, the existing monitoring system often cannot accurately identify and quickly adjust the response strategy, resulting in normal work activities may also be misjudged as security threats.
[0004] Therefore, there is an urgent need to provide a safety protection monitoring and management system for industrial plants, which can improve the flexibility of safety alarms while ensuring the safety protection effect, thereby reducing the false alarm rate and improving the safety management level of industrial plants. Summary of the invention
[0005] The present invention provides a safety protection monitoring and management system applied to industrial plants, which can improve the flexibility of safety alarms while ensuring the safety protection effect, thereby reducing the false alarm rate and improving the safety management level of industrial plants.
[0006] In order to achieve the above objectives, this application provides the following technical solutions:
[0007] A safety protection monitoring and management system applied to industrial plants, comprising an image acquisition module, a personnel identification module, a permission analysis module and an alarm module;
[0008] The image acquisition module is used to acquire image data of each working area of the industrial plant;
[0009] The personnel identification module is used to identify each person in the work area according to the image data, obtain the identity information of each person, and generate an identity identification result;
[0010] The authority analysis module is used to analyze the authority of the corresponding person according to the identity recognition result, and the authority includes work authority and temporary authority; if the identity recognition result of the current person shows that the person is a staff member, the work authority of the current person is obtained; if the identity recognition result of the current person shows that the person is not a staff member, the occupation of the current person is analyzed, and temporary authority is generated according to the occupation of the current person;
[0011] The alarm module is used to analyze whether the authority of the current personnel meets the authority requirements of the corresponding work area, and if not, generate alarm information.
[0012] Further, the authority analysis module includes a personnel analysis module, a career analysis module and a temporary authority generation module;
[0013] The personnel analysis module is used to analyze whether the current person is a staff member according to the identity recognition result, and if so, obtain the work authority of the current person; if not, jump to the occupation analysis module;

[0020] Furthermore, the authority analysis module also includes a professional capability analysis module and an abnormal situation analysis module;
[0021] The professional ability analysis module is used to analyze the professional ability of the current personnel according to the professional analysis results;
[0022] The abnormal situation analysis module is used to analyze whether there is an abnormal situation in the corresponding work area. If so, a pre-stored comparison table is called, which records a number of abnormal situations and a number of professional capabilities required for each abnormal situation, and combines the comparison table to analyze the rationality of the current personnel's stay and generate a rationality analysis result;
[0023] The temporary authority generation module is used to generate temporary authority for the current person according to the occupation analysis results and rationality analysis results.
[0024] Furthermore, the abnormal situation analysis module is used to analyze whether there is an abnormal situation in the corresponding work area, and if not, generate a reminder of abnormal stay of personnel.
[0025] Furthermore, the personnel identification module pre-stores the identity information and facial feature data of each staff member;
[0026] The personnel identification module is used to extract facial feature data of each person in the work area, and compare the facial feature data of the people in the work area with the pre-stored facial feature data of the staff, and obtain the identity information of the corresponding staff according to the comparison results to generate an identity recognition result.
[0027] The principles and advantages of the present invention are:
[0028] First, by analyzing the image data of the work area in real time, the identity of each person in each work area can be identified and their identity information can be obtained, which is conducive to ensuring that only authorized personnel enter specific areas and improving the security of industrial plants. At the same time, in order to prevent false alarms of personnel intrusion security alarms when external technical service personnel need to enter the plant to carry out equipment maintenance and other activities, this solution further introduces an occupational analysis mechanism on the basis of achieving identity identification. For non-staff members, the system will dynamically generate temporary permissions based on the current personnel's occupational attributes. This process significantly reduces the occurrence of false alarms of personnel intrusion security alarms caused by the normal entry and exit of external technical service personnel, and optimizes the accuracy and practicality of the security alarm system.
[0029] In order to further improve the accuracy of granting temporary permissions, the system also conducts intelligent analysis of abnormal situations in the work area, which is conducive to combining the current professional capabilities of non-staff members to analyze the rationality of the non-staff members' presence in the work area. If the presence of a non-staff member is reasonable, the corresponding temporary permissions will be granted; otherwise, if it is judged to be unreasonable, the temporary permissions will not be granted. For example: when equipment fails, maintenance personnel are required to intervene. At this time, if the professional capabilities of the non-staff members do not match the professional capabilities required to solve the equipment failure, it means that their presence in the corresponding work area is unreasonable; when staff members are injured, medical personnel are required to intervene. If the professional capabilities of the non-staff members match the professional capabilities required to deal with the injury, it means that their presence in the corresponding work area is reasonable.
[0030] In summary, this solution achieves efficient management of industrial plant safety through real-time monitoring and analysis, identity and occupation recognition, intelligent exception handling, and reasonable temporary authority control. It not only reduces the false alarm rate of safety alarms, but also improves the ability to handle emergencies, thereby improving the safety management level of the entire industrial plant. BRIEF DESCRIPTION OF THE DRAWINGS
[0031] Figure 1 The present invention is a logic block diagram of an embodiment of a safety protection monitoring and management system applied to an industrial plant.
[0032] Figure 2 The present invention is a logic block diagram of an authority analysis module in an embodiment of a security protection monitoring and management system applied to an industrial plant. DETAILED DESCRIPTION
[0033] The following is further described in detail through specific implementation methods:
[0034] Embodiment 1:
[0035] A safety protection monitoring and management system used in industrial plants, such as Figure 1 As shown, it includes an image acquisition module, a personnel identification module, a permission analysis module and an alarm module.
[0036] The image acquisition module is used to acquire image data of each work area in the industrial plant. In this embodiment, there are several work areas in the industrial plant, and each work area is set with authority requirements. Staff members enjoy corresponding work authority according to their respective work content, so that they meet the authority requirements for entering the corresponding work area, and the work authority of each staff member in the corresponding work area includes a stay time limit.
[0037] The personnel identification module is used to identify each person in the work area according to the image data, obtain the identity information of each person, and generate an identity identification result. Specifically, the personnel identification module pre-stores the identity information, facial feature data and work authority of each staff member. The personnel identification module extracts the facial feature data of each person in the work area, and compares the facial feature data of the people in the work area with the pre-stored facial feature data of the staff member, and obtains the identity information of the corresponding staff member according to the comparison result, and generates an identity identification result. If the identity identification result shows that the facial feature data of the current person does not match the facial feature data of all pre-stored staff members, it is determined that the person is not a staff member.
[0038] The authority analysis module is used to analyze the authority of the corresponding personnel according to the identification result, and the authority includes work authority and temporary authority. If the identification result of the current person is displayed as a staff member, the work authority of the current person is obtained; if the identification result of the current person is displayed as a non-staff member, the occupation of the current person is analyzed, and temporary authority is generated according to the occupation of the current person, so as to reduce the occurrence of false alarms of personnel intrusion security alarms caused by the normal entry and exit of external technical service personnel; Figure 2 As shown, the authority analysis module includes a personnel analysis module, a career analysis module, a career capability analysis module and a temporary authority generation module.
[0039] The personnel analysis module is used to analyze whether the current person is a staff member according to the identity recognition result. If so, the work authority of the current person is obtained. If not, the module jumps to the occupation analysis module. The occupation analysis module is used to analyze the current person's clothing according to the image data, and generate occupation analysis results according to the current person's clothing; the occupation analysis module includes a clothing analysis module, an occupation information acquisition module, an occupation ability analysis module, an abnormal situation analysis module and an occupation confirmation module.
[0040] The clothing analysis module is used to analyze the clothing of the current person according to the image data; specifically, the clothing analysis module pre-stores characteristic data of several occupations and corresponding professional clothing, obtains the characteristic data of the current person's clothing, compares it with the pre-stored characteristic data of professional clothing, and outputs the corresponding occupation determination result according to the comparison result. The occupation information acquisition module is used to obtain the occupation information of the current person according to the identity information of the current person; in this embodiment, the identity information of the current person is identified and verified by face recognition technology, and then the occupation information associated with the identity information is queried in the database according to the identity information of the current person. The occupation confirmation module is used to confirm the occupation of the current person according to the clothing and occupation information of the current person, and generate an occupation analysis result. Specifically, the occupation determination result generated by the clothing analysis module is compared with the occupation information of the current person queried by the occupation information acquisition module. If the comparison result is consistent, the corresponding occupation analysis result is generated. If the comparison result is inconsistent, a prompt of abnormal stay of the person is generated.
[0041] The occupational capability analysis module is used to analyze the occupational capability of the current personnel according to the occupational analysis results; in this embodiment, a correspondence table between occupations and occupational capabilities is pre-stored, and each occupation corresponds to a number of occupational capabilities. According to the occupational analysis results, the occupational capabilities corresponding to the corresponding occupations are output. The abnormal situation analysis module is used to analyze whether there are abnormal situations in the corresponding work area. If so, a pre-stored comparison table is called, and the comparison table records a number of abnormal situations and a number of occupational capabilities required for each abnormal situation. In combination with the comparison table, the rationality of the current personnel's stay is analyzed to generate a rationality analysis result; if not, a personnel abnormal stay prompt is directly generated. Specifically, the current personnel's occupational capabilities are analyzed to see whether they meet the number of occupational capabilities required for the abnormal situation, and a rationality analysis result is generated based on the number of compliance. The level of rationality is divided into eight levels from low to high, and the level of rationality is proportional to the number of compliance occupational capabilities.
[0042] The temporary authority generation module is used to generate temporary authority for the current person according to the occupation analysis result and the rationality analysis result. In this embodiment, if the occupation determination result generated by the dress analysis module in the occupation analysis result is consistent with the occupation information comparison result of the current person queried by the occupation information acquisition module, a temporary authority is generated for the current person, and according to the rationality level in the rationality analysis result, a corresponding temporary authority duration is generated, and the temporary authority duration is proportional to the rationality level.
[0043] The alarm module is used to analyze whether the authority of the current personnel meets the authority requirements of the corresponding work area, and if not, generate alarm information.
[0044] In summary, this solution achieves efficient management of industrial plant safety through real-time monitoring and analysis, identity and occupation recognition, intelligent exception handling, and reasonable temporary authority control. It not only reduces the false alarm rate of safety alarms, but also improves the ability to handle emergencies, thereby improving the safety management level of the entire industrial plant.
