Embodiment 1

[0082] Referring to Table 1, the detection device 1 is an alarm switch. When there is an illegal event, the security personnel press the button of the alarm switch to alarm, and the state of the detection device 1 is an alarm state. When the control device recognizes that the alarm switch is an alarm, the control The image acquisition device in video surveillance area 1 starts to collect video, and sends the captured video to the control device, and the control device recognizes the received video to determine whether there is occlusion, and if there is occlusion, determine the video surveillance area The state corresponding to 1 is the alarm state; whether the prevention and control area 1 where the control device is located is in the alarm state is determined according to the logic and operation of the state of the associated object. At this time, because the detection device 1 is in the alarm state, and the video surveillance area 1 is in the alarm state, Therefore, the stat...

Embodiment 2

[0084]

[0085] table 3

[0086] The detection device 2 is an infrared mobile detection device. When the detection device 2 detects a moving object, an alarm is issued, and the state of the detection device 2 is an alarm state. At this time, the detection device 2 controls the image acquisition device in the video surveillance area 1 to perform video acquisition, and Motion detection and occlusion detection are performed in the collected video. If there is a moving object or occlusion, the corresponding state is an alarm state. The process for the control device to determine the state of the prevention and control area 2 is the same as that in Embodiment 1, and will not be repeated here.

Embodiment 3

[0088]

[0089]

[0090] Table 4

[0091] The detection device 3 is an electronic fence, and an alarm will be generated when someone touches the electronic fence, and the state of the detection device 3 is an alarm state. Motion detection and occlusion detection are performed in the video collected by the image acquisition device. If there is a moving object or occlusion, the state of the corresponding video monitoring area is an alarm state, and the alarm output condition of the prevention and control area 3 is a logical OR of the state of the video area. Operation, the result and the state of detection device 3 are logically ANDed. If the state of a certain video monitoring area is an alarm state, because the state of the current detection device 3 is an alarm state, then the state of the prevention and control area 3 is an alarm state, and then the control device outputs an alarm signal for alarming.

Abstract

The embodiment of the present invention provides an area monitoring and alarm system and an alarm method. In the embodiment of the invention, a control device is set in each prevention and control area, and the control device stores an association table, and the association table records the control device When the prevention and control area where it is located is used as the first target object, the object associated with it can be the detection device or other target objects. If the state of the detection device or the target object changes and the alarm output trigger condition is met, the The control equipment sends an alarm, so real-time monitoring and alarming of illegal events can be realized.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to an area monitoring and alarm system and an alarm method. Background technique [0002] The safety protection system can protect the safety of important places, such as preventing personnel intrusion, detecting safety accidents, etc., and is used for event tracing. The security protection system mainly includes: video surveillance system, alarm control system, access control system, etc. These systems are independent and interrelated. [0003] The video monitoring system is used for monitoring and recording, and the alarm system outputs the front-end detection situation and its own abnormality in real time. In the past, security protection systems often used video alone for monitoring or sensors alone for monitoring, and the monitoring effect was poor. In order to improve the monitoring effect, technicians combine video monitoring and sensor monitoring, and use cameras...
