Example one
Referring to fig. 3, the system logic components of the present invention include:
1. the electronic fence host computer: each electronic fence is provided with an electronic fence host, and when a touch event occurs, the electronic fence host generates an alarm message A1.
2. Fence warning host computer: each fence alarm host is connected with a plurality of electronic fence hosts and is responsible for collecting and forwarding alarm messages.
3. Alarm collection service: each alarm collecting service is connected with a plurality of fence alarm hosts and is responsible for collecting and forwarding alarm messages.
4. And (3) warning message queue: the alert message queue is used to temporarily store messages to notify the consumer that new messages are coming.
5. And (4) warning and warehousing service: the alarm warehousing service is responsible for writing alarm messages to the database.
6. A relational database: the relational database is used for permanently storing the alarm messages.
7. Alarm video collection service: the warning video collection service is connected with the camera and used for collecting warning video data.
8. The alarm management web server: the method is used for realizing business logic and providing service for the alarm station.
9. The warning platform, the user passes through warning platform and system interaction, and the function includes: view historical alarms, receive alarms, and the like.
The following describes the alarm implementation process by taking an intrusion event as an example: generating 3 system alarm messages in sequence for one event, wherein the message A is an electronic fence alarm; the message B is a camera picture alarm; and the message C is a camera video alarm.
When an intrusion event occurs, the intruder touches the electronic fence and the electronic fence generates an alert message a 1. The fence alarm host receives the message A1, generates a message A2, and the message A2 contains the event occurrence time, the number of the defense area and other information. The fence alert message a2 is passed to the alert collection service component and the system immediately generates an alert message A3, a fence alert. The message is then sent to an "alert message queue". Multiple consumers process message a3 in parallel, with the alert station receiving the message immediately sounding an alert and displaying the fence location. The user sees the alert. The alarm video collection service intercepts the picture of the current video frame and sends a message B, namely a camera picture alarm. The alarm video collection service collects 3 minutes of video (the specific duration is a parameter of the system, and according to the actual situation, the parameter can be flexibly adjusted for each camera, for example, the parameter can be set to be 2 minutes before an event occurs to 1 minute after the event occurs), and then sends out a message C that the camera video alarms. And finally, the alarm station processes the message B, and the user sees the picture alarm. The alarm station processes message C and the user sees a video alarm.
In the process, the 3 messages of one event are finally combined into a whole to be displayed on the alarm desk. Meanwhile, the process of message collection is realized by adopting a hierarchical structure, so that the flexible capacity expansion requirement can be met, and tens of thousands of cameras and fences can be supported. In addition, the message queue mode is adopted in the message processing process, asynchronous processing requirements can be met, system performance can be improved, and low delay requirements can be met.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the technical scope of the present invention should be included in the scope of the present invention.
