The embodiment of the application provides a system, a method, a computer device and a medium for processing national standard camera alarm information, which are respectively described in detail below.
Referring to fig. 1, in an embodiment, a system 10 for processing national camera alarm information is disposed on a server between a national camera 20 at a front end and an alarm receiving and displaying end, and includes:
the equipment access manager 101 is used for acquiring alarm information reported by each national standard camera at the front end;
in the present embodiment, the national camera 20 at the front end refers to a national camera with an alarm function. The device access manager 101 may be used to handle access by a national camera and maintain communication link stability.
The alarm isolation buffer 102 is configured to store the alarm information acquired by the device access manager 101 in a preset cache table 1024, determine the number of alarm information reported by each national standard camera among a plurality of alarm information stored in the cache table 1024, and forward all alarm information reported by target national standard cameras, of which the number of alarm information is greater than the preset number, to a preset alarm message pool 1025;
in this embodiment, the alarm isolation buffer 102 is an independent processing thread, and is independent from the security monitoring service processing thread of the server. The alarm isolation buffer 102 receives the alarm information acquired by the device access manager 101, and maintains and manages the original alarm information, thereby playing a role in isolating alarm processing logic and service logic. In addition, the alarm isolation buffer 102 notifies the message merging classifier 103 to process after the alarm information of the national standard camera reaches a certain amount, and the batch processing mode can avoid the problem of low performance caused by 'coming one and processing one'. Of course, the alarm isolation buffer 102 may also notify the message merging classifier 103 at regular time to process, for example, notify the message merging classifier 103 every 5 seconds, so as to periodically forward the alarm information stored in the cache table 1024 to the preset alarm message pool 1025, thereby avoiding the problem of untimely alarm.
The message merging classifier 103 is configured to determine an alarm type to which each alarm message reported by the target national camera in the alarm message pool 1025 belongs, and merge the alarm messages reported by the target national camera and belonging to the same alarm type to obtain merged alarm messages corresponding to the target national camera;
in this embodiment, the message merging classifier 103 may be configured to receive the sorting notification of the alarm isolation buffer 102, sort and merge alarm information according to the cameras, and merge the alarm information according to the camera codes and the alarm types to form merged alarm information in which a single camera merges according to the alarm types, where the camera codes corresponding to different cameras are different.
And the event synchronization manager 104 is configured to send the merged alarm information corresponding to the target national standard camera to the alarm receiving and displaying end 30.
In this embodiment, the event synchronization manager 104 may be configured to receive a subscription request of an alarm receiving and displaying terminal, where the request identifies which alarm types of alarm information are interested by the alarm terminal, and hooks the type to the message merging classifier 103, and the message merging classifier 103 calls back to notify the alarm receiving and displaying terminal 30 to display the type of the message after acquiring the type of the message. The alarm receiving and displaying terminal 30 may include any CS (Client/Server) and BS (browser/Server) Client sub-modules for displaying an alarm prompt, and may subscribe to the alarm information in the event synchronization manager 104 according to types through http and websocket protocols.
In this embodiment, the processing system 10 for national standard camera alarm information may be implemented by C + + language. After the national standard camera is accessed through the access manager, the alarm information sent by the front-end national standard camera is completely received by the alarm isolation buffer 102, then the information is summarized by the message merging classifier 103 according to the camera and the alarm type generated by the camera, and the summarized alarm information is consumed by the event synchronization manager 104 and is displayed to the alarm receiving and displaying terminal 30 according to classification. By adding and designing the alarm isolation buffer 102 at the server, the alarm information enters a special information pool, and the alarm information and normal server service are separated, so that the processing of other logics cannot be influenced by a large amount of received alarm information, and the performance is improved. In addition, for the same camera and the same type of alarm information, under the condition of small difference, the special message merging classifier 103 is used for merging the same type of messages, and the same type of alarm information with small difference is displayed by times, so that the alarm data volume is greatly reduced, the terminal can only display the summary result for the same type of alarm within a certain time instead of repeatedly displaying the notification, the user experience is greatly improved, and the communication bandwidth is saved.
In the technical scheme disclosed in this embodiment, a large amount of alarm information is cached through the alarm isolation buffer 102, and then the large amount of alarm information is combined according to the camera and the alarm type, so that the terminal can only display the alarm summary result, and the phenomenon that the message of the terminal is inundated and a large amount of alarm popup windows are continuously popped up is avoided.
In another embodiment, as shown in fig. 2, based on the embodiment shown in fig. 1, the device access manager 101 includes:
a link maintaining module 1011, configured to maintain a communication link with each national standard camera at the front end, so as to obtain national standard information on the communication link;
in this embodiment, after the national standard camera 20 at the front end is started, when registering with the device access manager 101 using the national standard protocol, the link maintenance module 1011 performs communication link maintenance, heartbeat management, periodic link state detection for each registered camera, and forwards the message on the link to the alarm message screening module 1012 for consumption.
An alarm message screening module 1012, configured to obtain alarm information in the national standard information;
in this embodiment, the alarm message screening module 1012 may read the message of the message pipe in the link maintenance module 1011, and if the message is the alarm message resolved by the national standard, the message is extracted.
The alarm device management module 1013 is configured to send the alarm information identified by the alarm message screening module 1012 and the camera information of the international camera reporting the alarm information to the alarm isolation buffer 102 in an associated manner, so as to store the alarm information and the camera information sent in the associated manner in the cache table 1024 in an associated manner.
In this embodiment, the alarm device management module 1013 may create a file for each camera to which the alarm information belongs, that is, organize the original alarm information of a single camera according to a camera, and transmit the original alarm information to the alarm isolation buffer 102.
In this embodiment, the operation sequence of the device access manager 101 is as follows:
(1) when the national standard camera is registered, the link maintaining module 1011 maintains the connection with the camera, and once a national standard message is connected, the national standard message is put into a message pipeline of the link maintaining module;
(2) the alarm device management module 1013 may analyze the messages in the message pipe of the link maintenance module 1011 and invoke the alarm message screening module 1012 to parse the message type. If the alarm information is alarm information, the alarm device management module 1013 queries a camera object in its own cache, and if the object exists, puts the message into an alarm list to which the object belongs, and if the object does not exist, discards the message;
(3) the alarm device management module 1013 finds that a camera in the link maintenance module 1011 is dropped, searches for the camera object, cleans up the camera object, and sends the drop information to the following in a logic flow in an event bubble manner, for example, notifies the alarm isolation buffer 102, the message merging classifier 103, the event synchronization manager 104, and the like to perform cleaning operation one by one until reaching the alarm receiving and displaying end 30 of the terminal, and notifies the camera of the drop.
In the technical solution disclosed in this embodiment, the device access manager 101 is used for access management of the front-end national standard camera, maintaining a communication link, separating service information and alarm information, managing an alarm device, and forwarding the alarm information of the alarm device to the alarm isolation buffer 102.
In yet another embodiment, as shown in fig. 3, based on the embodiment shown in any one of fig. 1 to 2, the alarm isolation buffer 102 includes:
an isolation thread module 1021, configured to create an isolation thread, and receive, through the isolation thread, alarm information sent by the device access manager 101;
in this embodiment, the isolated thread module 1021 acquires alarm information transmitted by the device access manager 101 through inter-thread message transmission, and the information is processed in the isolated thread. The isolation thread module 1021 is mainly used for thoroughly separating common service services such as alarm information processing and security monitoring of a platform, and the isolation thread is a thread for specially processing messages, so that the service processing and the alarm information processing are located in different threads, and mutual interference and consumption performance cannot be caused.
The thread-crossing data proxy module 1022 is configured to create a thread-crossing data proxy thread, forward the alarm information in the isolation thread to the cache table 1024 through the thread-crossing data proxy thread, determine the number of alarm information reported by each international camera in a plurality of alarm information stored in the cache table 1024, and forward all alarm information reported by target international cameras whose number of alarm information is greater than a preset number to a preset alarm message pool 1025, where the thread-crossing data proxy thread and the isolation thread belong to different threads.
In this embodiment, cross-thread data proxy module 1022 may be configured to proxy alarm data in an isolated thread, where the cross-thread data proxy thread is in the same thread as alarm message pool 1025 and is a different thread from the isolated thread, so that message processing logic may be further separated by the thread. And after the cross-thread data proxy thread acquires the alarm information, storing the alarm information into a preset cache table 1024. The cross-thread data proxy thread is also used to synchronize the cache table 1024 with alarm information in the alarm message pool 1025. Because the cross-thread data proxy thread for storing the alarm information is different from the isolation thread for receiving the alarm information, when the national standard camera 20 at the front end feeds back a large amount of alarm information, a large amount of alarm information only blocks up in the isolation thread, and the cross-thread data proxy thread is not affected, so that the reporting stability of the alarm information of the national standard camera is ensured.
In this embodiment, the preset cache table 1024 is used for storing all alarm information related to the camera according to the camera, that is, storing the alarm information according to the mapping relationship between the camera and the alarm information.
In this embodiment, the cross-thread data proxy thread synchronizes data in the preset buffer table 1024 to the alarm message pool 1025 at regular time, for example, after receiving alarm information of a certain camera, the cross-thread data proxy thread stores the alarm information into the buffer table 1024, and for the number of the alarm information of the camera +1, when detecting that the number of the alarm information of the camera reaches a certain threshold, for example, 20 alarms are reached, the cross-thread data proxy thread reads the alarm information of the camera in the buffer table 1024 and stores the read alarm information into the alarm message pool 1025.
Optionally, the alarm isolation buffer 102 further comprises a life cycle detection module 1023. The life cycle detection module 1023 is configured to acquire states of the national cameras at the front end, and delete alarm information reported by the national cameras in an offline state in the cache table 1024 when the national cameras are in the offline state, and/or acquire cache duration of each alarm information in the cache table 1024, and delete alarm information whose cache duration is greater than a preset duration in the cache table 1024 when the cache duration is greater than the preset duration. That is, the life cycle detecting module 1023 can detect the camera status and the alarm information status. And if the camera is offline, clearing the cache of the camera-alarm information. If the alarm information of the camera does not enter the alarm message pool 1025 for a long time, the operation of clearing the message can be carried out.
In the present embodiment, the operation sequence of the alarm isolation buffer 102 is exemplified as follows:
(1) the isolation thread reads the message accessed in the manager 101 by the device and stores the message in the thread data stack of the isolation thread;
(2) after the cross-thread data agent thread reads the information, the information is firstly put into a cache table 1024 mapped by the camera-alarm information, and information related to life cycles such as storage time, alarm time, camera state and the like is marked;
(3) the life cycle detection module 1023 carries out timing detection aiming at the life cycle identifications, cleaning operation is carried out on the camera in an overtime and disconnection state, and the cleaned data cannot enter the alarm message pool 1025;
(4) and detecting whether the alarm information reaches a threshold value or not when the cross-thread data agent thread stores the alarm information for each camera every time. If the threshold value is reached, reading the camera object and all alarm data thereof, and putting the camera object and all the alarm data into an alarm message pool 1025;
(5) the message merge classifier 103 consumes the information and groups the information in units of cameras and alarm types as tags for a sorting operation.
In the technical scheme disclosed in this embodiment, the alarm isolation buffer 102 functions as if people take water, and can only be directly taken against water flow without a cup, which has a high requirement for real-time treatment of people. However, if there is a cup, the cup can be taken with water first and then taken, and the buffering function is to receive the alarm information, then to perform primary classification, and then to store the alarm information in the alarm information pool 1025, and to wait for the information to merge with the classifier 103 for consumption.
In yet another embodiment, as shown in fig. 4, based on the embodiment shown in any one of fig. 1 to 3, the message merging classifier 103 includes:
a message sorting and routing module 1031, configured to obtain alarm information from the alarm message pool 1025;
in this embodiment, the message sorting and routing module 1031 reads the original alarm information from the alarm message pool 1025, and calls the alarm information one by one to the alarm type grouping module 1032 to perform the alarm type grouping module, and the grouped message is put into the callback pointer pool according to the alarm type, and the type callback method triggers the event synchronization manager 104 to process the message and notifies the alarm receiving and displaying end 30 to display the message.
An alarm type grouping module 1032, configured to determine an alarm type to which the alarm information obtained by the message sorting routing module 1031 belongs, and perform combination processing on the alarm information that is reported by the target international camera and belongs to the same alarm type, to obtain combined alarm information corresponding to the target international camera.
In this embodiment, the alarm type grouping module 1032 may include at least one of a type grouping submodule, an event grouping submodule, and a code grouping submodule. Specifically, the alarm information of the same camera is grouped and merged according to different types. For example, camera a read from alarm message pool 1025 contains 50 different alarm messages, type grouping can be grouped and summarized according to alarm and alarm without person, event grouping can be grouped and summarized according to intrusion event, code grouping can be grouped and summarized according to the code of national standard camera of alarm, and finally, the sorted data under the camera is obtained: personnel detection alarm (10 times), intrusion event alarm (20), and coding alarm (20).
Optionally, the message merge classifier 103 further comprises a callback pointer pool module 1033 for storing the merged alarm information generated by the alarm type grouping module 1032. The pointers in the callback pointer pool are associated to the event synchronization manager 104 by the alarm receiving and displaying end 30, and the function pointers are stored in the callback pointer pool by the event synchronization manager 104. Therefore, the pointers in the callback pointer pool module 1033 are event function pointers in the event synchronization manager 104, and these pointers carry type identifiers, for example, a certain pointer carries an identifier of an intrusion detection type, and the alarm information of the intrusion detection type put in by the message sorting and routing module 1031 is passed to the space of the function body pointed by the pointer, and the function body is located in the event manager and will trigger execution. The event synchronization manager 104 includes a coordination module 1041 and a protocol agent module 1043. The coordination module 1041 is configured to obtain, by using the function pointer of the event processing function 1042, the merged alarm information in the callback pointer pool module 1033; the protocol agent module 1043 is configured to send the combined alarm information obtained by the coordination module 1041 to the alarm receiving and displaying end 30.
Optionally, the protocol agent module 1043 is further configured to receive a subscription message sent by the alarm receiving and displaying end 30, and acquire a target alarm type subscribed in the subscription message; the coordination module 1041 is configured to obtain, by using a function pointer of the event processing function 1042 corresponding to the target alarm type, merged alarm information belonging to the target alarm type in the callback pointer pool module 1033; the protocol agent module 1043 is configured to send the merged alarm information belonging to the target alarm type and acquired by the coordination module 1041 to the alarm receiving and displaying end 30 subscribed with the target alarm type. Specifically, the protocol agent module 1043 may receive subscription information of the alarm receiving display end 30, and the protocol agent externally provides a subscription interface mode such as http, websocket protocol, and message queue. If the alarm receiving/displaying terminal 30 wishes to receive some type of alarm information, the specified message type is sent to the module through these interfaces. The event processing function 1042 may create an event function according to the message type, and after the event function is declared, its entry address is returned to the creator as a callback function pointer. The coordination module 1041 may coordinate the subscription message of the protocol agent module 1043 and the event processing function 1042, binding them into a one-to-one correspondence relationship, and putting the pointer of the event processing function 1042 into the callback pointer pool module 1033 of the message merge classifier 103. It is understood that the event synchronization manager 104 is primarily used to convert alarm information into event notifications and return the notifications to the alarm receiving presenter 30 via a protocol agent.
In the present embodiment, the logical operation sequence of the message merge classifier 103 and the event synchronization manager 104 is exemplified as follows:
(1) the alarm receiving and displaying end 30 subscribes some kind of alarm information, such as intrusion detection alarm, to the event synchronization manager 104 through an http interface;
(2) after receiving the request, the protocol agent module 1043 analyzes, analyzes and verifies the request, and reports the parameters to the coordination module 1041 after the request is qualified;
(3) the coordination module 1041 creates an intrusion detection alarm event notification processing function, and puts a function pointer into a callback pointer pool;
(5) after the message sorting routing module 1031 sorts out intrusion detection alarm information, an intrusion detection alarm event notification processing function is called; when the function is executed, the alarm information is returned to the coordination module 1041, and the coordination module 1041 transfers the alarm information to the protocol agent module 1043;
(5) the protocol agent module 1043 packages the alarm information by http protocol and returns the information to the alarm receiving and displaying end 30 for alarm displaying; the protocol agent module 1043 also notifies the alarm receiving and displaying terminal 30 of the disconnection of the device.
In the technical solution disclosed in this embodiment, the message merging classifier 103 is mainly used for sorting and merging operations for message types, events, codes, and the like, and meanwhile, encapsulates the sorted and merged message to a callback pointer pool, and executes event notification callback to trigger the event synchronization manager 104 to push alarm information to the alarm receiving display terminal.
In the system 10 for processing national standard camera alarm information according to the above embodiments, the alarm isolation buffer 102 is used to replace the conventional logic (one-time alarm processing), and batch processing is used instead, so that the overall processing logic of the system is improved. In addition, the incidence relation between the alarm processing and the normal business logic is isolated through the single-row alarm processing thread, so that the processing capacity of the normal business process is enhanced, and the performance is greatly improved. In addition, the alarm sorting enables a large amount of alarm information to be organized according to types instead of single and irregular popping up, the problem that a large amount of alarm pop-up windows are arranged on an alarm display client side is solved, and user experience is improved. After the batch processing of the cache is adopted, the throughput of the system for processing the alarm information is greatly increased. In addition, the use of the isolation thread enables the concurrent processing capacity to be enhanced, the alarm and normal logic are processed in parallel, module-level full-time processing is achieved, the processing peak value of an information storm caused by a large amount of alarm information in the system is not easy to generate, the request is stabilized, and the throughput is increased. In addition, alarm information classification also enables the alarm receiving and displaying end 30 to subscribe concerned alarms according to alarm types, so that messy popup notification is avoided, and user experience is improved.
