Detailed Description
Enterprises have various potential safety hazards in the field overhaul process, and the safety protection requirements corresponding to different overhaul procedures also have differences. At present, enterprises can only reduce safety risks in the overhaul process through safety training and on-site safety manpower supervision. However, the method has the disadvantages of great manpower input, low efficiency, frequent occurrence of safety accidents in the process of maintenance and difficult prevention. The safety management defects existing in the traditional maintenance process can be mainly summarized into the following five points:
(1) safety regulations in the overhaul process only depend on the consciousness and responsibility consciousness of people to abide by the requirement that overhaul safety work requirements are difficult to meet.
(2) Safety violation behaviors in the maintenance process are difficult to perform substantial punishment only by depending on supervision of personnel, and safety violation information is difficult to collect process data used for traceable management and is used as an important basis for determining liability after an accident occurs.
(3) The conventional overhaul portfolio only includes information such as specific overhaul procedures, related overhaul spare parts, and overhaul personnel preparations. Corresponding protection means and safety articles are not provided for potential safety hazards in specific overhaul procedures.
(4) In the maintenance process, the work area where the execution working procedure is located needs to be cleared, and irrelevant personnel cannot enter the work area. However, in the field maintenance process, due to various reasons, the corresponding work area after the process is performed cannot completely control the entrance and exit of personnel, and there is a case that no person enters.
(5) The recovery and counting records of the safety articles and the examination and approval sheet reported by the recovery and counting missing are recorded in a paper file mode. The approval process needs multi-stage approval, and is tedious and time-consuming, and meanwhile, the paper files cannot be guaranteed to be intact in the step-by-step delivery process, and the phenomenon of file breakage or even damage can occur. In addition, these paper-based records are difficult to centrally review and count.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1, an embodiment of the present invention provides a security management system, which includes a data acquisition layer, a data access layer, a data storage layer, a service layer, and an interaction layer, where the data acquisition layer, the data access layer, the data storage layer, the service layer, and the interaction layer are connected to each other through a real-time data bus; the data acquisition layer is used for acquiring security data containing on-site overhaul violation information and transmitting the security data to the data access layer; the data access layer is used for receiving the security data, analyzing the security data into unstructured data and transmitting the unstructured data to the data storage layer and the service layer; the data storage layer is used for receiving and storing the unstructured data and receiving and storing the service data transmitted by the service layer; the business layer is used for receiving the unstructured data, triggering corresponding rule conditions according to the unstructured data, executing operation contents under the rule conditions, and transmitting the business data to the data storage layer; the interaction layer is used for interacting with a system user and comprises: and receiving an instruction issued by the system user to control the service layer to execute the corresponding service, and transmitting the security data to the system user.
Specifically, in this embodiment, the security management system includes a data acquisition layer, a data access layer, a data storage layer, a service layer, and an interaction layer, where each layer is sequentially arranged from bottom to top, each lower layer provides information service to a corresponding upper layer, receives an instruction from the upper layer, and performs a corresponding action, and the upper layer and the lower layer are connected through real-time data bus communication.
The data acquisition layer is the lowermost layer and is used for acquiring safety data, for example, acquiring low-frequency information through intelligent safety articles such as an intelligent safety helmet and the like, wherein the safety helmet is provided with a low-frequency label scanner. Other protective articles for wearing, such as protective clothing, goggles, etc., are provided with low frequency tags. When the protective articles are to be worn, they are scanned across the helmet and the system is considered to be the moment when the protective articles are worn by the service person. And after the corresponding security data are acquired, transmitting the security data to a data access layer.
The data access layer is an upper layer of the data acquisition layer, and after receiving the security data, the data access layer analyzes the security data into unstructured data, transmits the unstructured data to the data storage layer for storage, and transmits the unstructured data to the service layer to provide corresponding service.
The data storage layer is an upper layer of the data access layer, and the data storage layer can receive and store unstructured data transmitted by the data access layer and can receive service data transmitted by the service layer so that the service layer can call the unstructured data when needed.
The service layer is an upper layer of the data storage layer, receives unstructured data transmitted by the data access layer, triggers corresponding rule conditions according to the unstructured data, and executes operation contents under the rule conditions, and calls the service data from the data storage layer.
Wherein, the interaction layer is the upper strata of business layer, and the interaction layer is used for interacting with system user, includes: receiving an instruction issued by a system user to control the service layer to execute the corresponding service, and transmitting the security data to the system user.
Wherein, about the hardware part, the power plant mainly uses three types of safety supplies when overhauing, is protective articles, safety device and safety management and control equipment respectively. The protective articles are used for protecting the personal safety of maintainers, and mainly comprise work clothes, safety helmets, work shoes, safety belts, gloves, protective glasses and the like. The safety facility is used for protecting an overhaul field and mainly comprises a hole cover plate, an intelligent fence, a scaffold, an entrance and exit gateway, a fixed monitoring base station and the like.
The software part relates to workflow service design, rule engine service design and system rule loading and removing processes.
As shown in fig. 2, the workflow service design includes a BPMN design of a file package security information flow process. The file package safety information circulation is designed according to the specific circulation condition of the electric power enterprise maintenance file package, and the file package state can be divided into fourteen states according to the actual condition, which are respectively: compiling, examining and verifying, reviewing, approving, packaging, unpacking information input, accepting by a party B, returning to the original, overhauling, recovering and checking safety supplies, filling finished data and archiving the files. When a file package writer writes file package safety information, a file package is in a writing state, after all items of basic information and safety information are recorded and set, the file package writing completion can be clicked in an audit task billboard, the file package is in an audit state and flows to an audit task of a corresponding audit role, and after all users with the audit roles audit the file package safety information, the file package enters the next flow after the audit is passed. The state of the file package security information flow is switched similarly.
As shown in fig. 3, the workflow service design further includes a violation alarm removal application circulation process BPMN design. The on-site violation alarm can affect the normal execution of the process flow. After the violation alarm is generated, the on-site maintenance terminal can suspend the current process and cannot continue to execute the next process. If the execution of the process is to be continued, a violation alarm removing application is required to be provided, and the next process can be continued after the confirmation of a field security officer and the approval of a maintenance project manager.
The workflow technology is utilized to provide functions of auditing and circulating the safety information of the file packet, canceling the violation alarm, applying for auditing and circulating, recovering, checking and reporting the missing for auditing and circulating for the maintenance and safety management, automatically distributes the auditing tasks to corresponding responsible persons, records the information of the circulating process, and provides a foundation for traceability of responsibility. Meanwhile, unnecessary manpower and material resources are saved for off-line stage-by-stage examination and approval by the system, and the efficiency of maintenance safety management is greatly improved.
Compared with the traditional system in which the established flow template cannot be modified, the system provides the function of dynamically allocating and deploying the flow template, so that the flow service in the system can be correspondingly changed in compliance with the business adjustment, and the dynamic deployment of the flow template is realized under the condition of not influencing the operation of the original system. The function further improves the flexibility of the system and better meets the non-functional requirements of enterprises on the system.
As shown in fig. 4, the workflow service design further includes a BPMN design for recovering, counting, missing, reporting and circulating processes. And the recovery counting missing reporting audit provides a function of counting missing reporting audit when the safety supplies are recovered after the overhaul is finished. The field security officer reflects the missing condition to the maintenance project manager, and after the maintenance project manager audits, the maintenance task can be finished only after the inspection project manager passes the approval of the first-party responsible person, and meanwhile, the system can record the missing condition.
As shown in fig. 5, all the safety supplies in the same overhaul site belong to the same file package, the safety supplies are divided into different groups according to the specific conditions in the overhaul site, and the safety supplies in each group have the same data processing rule. The system establishes a KieContainer for each file package according to the definition of the file package rule of the service database, and all the rules contained in the file package are stored in the KieContainer. The rules stored by the kiecondainer are grouped, with the groups corresponding to groups of portfolio security supplies. Therefore, when the data of the safety supplies are generated, the rules corresponding to the file package in the internal memory of the rule engine can be found through the file package where the safety supplies are located (the corresponding KieContainer is found), and then a specific rule group is found through grouping of the safety supplies.
The system realizes the close combination of on-site safety control and maintenance process flow, provides corresponding protection means for different potential safety hazards by adding corresponding safety articles such as protective articles, safety facilities, safety control equipment and the like in specific procedures, adds the personnel access and exit white lists of different maintenance work areas, controls the access of on-site personnel and reduces the possibility of safety accidents caused by irrelevant personnel. Compare the safe management and control effect outstanding and accord with actual demand more with former system, further improve on-the-spot safety control level.
The rule engine service comprises three sub-services of rule analysis, rule management and rule execution, and the rule analysis service splices rule data character strings in the business database into drl rules of the Drools rule engine. The loading service of the rule management service is used for compiling and loading drl rules into the rule engine product memory, and the removing service is used for removing the file package rules from the rule engine memory. The rule execution service firstly obtains the KieContainer of the corresponding file package from the KieContainermap through the file package Id of the data, and then the executor executes the rule. During the execution process, the executor inserts safety information such as violation information into the system service database.
In combination with fig. 6, when the system is started, the system loads some default rules that are not changed frequently into the system memory first for other rules to call. In the process of compiling the document package, the document package compiler can set data processing rules for the required safety supplies according to the specific overhaul scene, and the rules are compiled by the document package compiler in a condition part and an execution part of the rules in a configuration page of the rules. When the file package passes the operations of auditing, packaging, unpacking and the like, and the file package is activated by a maintenance responsible person in a maintenance site, the system generates all rules of the file package into rules which can be executed by a Drools rule engine through character string splicing operation, compiles the rules and loads the rules into a system memory, and if the rules are not compiled, the file package is handed to a file package writer for checking. The file packet compiled by the rules can be overhauled on site, and the intelligent safety article data generated on the overhaul site can execute the established business logic through the rule verification. Because the system memory is limited, it is not possible to load the rules in unlimited amounts, and when a bundle is repaired, the system will remove all the rules belonging to the bundle from the memory. At this point, the life cycle process of the safety data processing rule is finished.
In this embodiment, through the information technology improvement tradition maintenance safety management mode, combine software and hardware to realize that the on-the-spot operation safety of overhauing is controllable, effectively practice thrift on-the-spot safety control manpower resources, improve the safety control level of maintenance process, the safety and stability operation of guarantee maintainer personal safety and equipment conscientiously.

Since the connection-type protocol is not adopted, the method has the advantages of low resource consumption and high processing speed, so that the UDP is frequently used for transmitting audio, video and general data, and the UDP does not have great influence on the receiving result even if one or two data packets are occasionally lost. Therefore, the udp protocol is adopted for the secure data transmission, which is beneficial to improving the effectiveness of the secure data transmission.
