the shooting control unit 401 is configured to start the image acquisition device to acquire image data when the monitoring position is within a coverage range of the image acquisition device;
a data sending unit 402, configured to send the image data to the server.
In this embodiment, after determining whether there is a human border crossing according to the monitoring result, two pieces of information can be obtained: firstly, human activities exist, and secondly, the positions and corresponding moments of the human activities exist; because the monitoring equipment is arranged on a longer border line, if people pass by, image data can be obtained under the condition that the condition allows; the image data can be used as a basis for further confirming the activities on the one hand, and can obtain more information of the border crossing personnel on the other hand, so that a basis is provided for the following catching or detecting work.
In an optional implementation manner, since the monitoring devices are all disposed near the obstacle, and usually have a power supply device, in some cases, the monitoring devices can be in a more sensitive working state, and the monitoring performance is improved, specifically as follows: as shown in fig. 5, the control apparatus further includes:
a monitoring control unit 501, configured to increase a monitoring frequency and/or a monitoring sensitivity of the monitoring device if the monitoring result includes one type of result data.
In this embodiment, because it is not necessary to consider the power supply problem, the monitoring device may be in a working state all the time, but the monitoring device may have an influence on the service life when working under the highest load and is still relatively power-consuming, the embodiment of the present invention provides the above solutions to solve the two problems, so that the monitoring device can obtain a certain rest time, and the energy consumption of the whole system is reduced.
In an alternative implementation, the human-characteristic voiceprint includes:
at least one of a characteristic voiceprint of a metal impact sound, a characteristic voiceprint of a speech-like voice, and a characteristic voiceprint of a human footstep sound.
In the embodiment, at least two human characteristic voiceprints are adopted, so that misjudgment can be reduced; missing judgments can be reduced if a human characteristic voiceprint is used in the event that a simultaneous vibration is monitored. It should be noted that the human characteristic voiceprint is not necessarily the sound emitted by the human being itself, for example: the sound of a speech; but also sounds that arise due to human activity, such as: various unnatural sounds, more specifically for example: metal impact, clothing friction, footstep sounds, etc., which are different from the sounds that the natural environment itself can make, which have the characteristics of typical human activities, all of which can be considered as characteristic voiceprints of humans. In addition, under the condition of using two or more than two kinds of human characteristic voiceprints, the requirement on the human characteristic voiceprints can be reduced, the similarity requirement during the comparison of the characteristic voiceprints can also be reduced, and the identification accuracy can still be ensured.
An embodiment of the present invention further provides a control device, as shown in fig. 6, including: a processor 601, an input-output device 602, a memory 603; a battery or other power supply device may also be included, wherein the processor 601 is configured to control execution of: receiving a monitoring result of the monitoring equipment; the monitoring result comprises: vibration information of the obstacle, vibration information of one side of the obstacle, and human characteristic voiceprint information; and determining whether the human is out of the border according to the monitoring result, and if so, sending an out-of-border alarm to a server.
Optionally, the monitoring device comprises: the first monitoring sub-device is located on the obstacle, and the second monitoring sub-device is located on one side of the obstacle;
the monitoring result comprises: the first monitoring sub-device monitors vibration information caused by friction or impact of the obstacle, and at least one of the human characteristic voiceprint information monitored by the first monitoring device and/or the second monitoring sub-device and ground impact vibration information monitored by the second monitoring sub-device.
The processor 601 is configured to control execution of: determining whether human crossing exists according to the monitoring result, if so, sending a crossing alarm to a server comprises the following steps:
if the obstacle has vibration or vibration exists on one side of the obstacle, and human characteristic voiceprint information exists; or if the obstacle has vibration, vibration caused by collision exists on one side of the obstacle; or, if two or more than two human characteristic voiceprints exist, the border crossing is confirmed, and a border crossing confirmation alarm is sent to the server;
and if the obstacle has vibration and/or vibration of the same type as the obstacle exists on one side of the obstacle, or the vibration information is not monitored and only one type of human characteristic voiceprint is contained, confirming suspected crossing, and sending a crossing alert alarm to the server.
Further, the processor 601 is further configured to control to perform: and under the condition that the crossing or the suspected crossing is close, determining a monitoring position of the crossing or the suspected crossing, and under the condition that the monitoring position is within the coverage range of the image acquisition equipment, starting the image acquisition equipment to acquire image data and sending the image data to the server.
Further, the processor 601 is further configured to control to perform: in case the monitoring result comprises a result data, the monitoring frequency and/or the monitoring sensitivity of the monitoring device is increased.
It should be noted that, in the embodiment of the control device in the system embodiment, each included unit is only divided according to functional logic, but is not limited to the above division as long as the corresponding function can be implemented; in addition, specific names of the functional units are only for convenience of distinguishing from each other, and are not used for limiting the protection scope of the present invention.
