Virtual security device

Abstract

A virtual security device includes a mobile unit and a main body. The main body includes an image capture module, an audio transceiver module, a processing module, a display module, and an interaction module. The image capture module captures real-time video. The audio transceiver module receives and broadcasts audio. The processing module is connected to the image capture module and the audio transceiver module. In standby mode, it determines whether someone is approaching in the real-time video or detects the presence of a wake-up word in the audio signal received by the audio transceiver module, and then enters service mode. The interaction module is connected to the processing module, the display module, and the mobile unit. When entering service mode, in response to the processing module detecting a resident, it controls the display module to display the resident's service interface.

Claims

1. A virtual security device, comprising: a mobile unit that moves in response to a guidance signal; and a body connected to the mobile unit, and comprising: an image capturing module configured to capture a real-time image; an audio transceiver module configured to receive and broadcast audio; and a processing module electrically connected to the image capturing module and the audio transceiver module, configured to determine in a standby mode whether a person is approaching in the real-time image or whether a wake-up word is detected in an audio signal received by the audio transceiver module, wherein the standby mode is terminated and enters a service mode in response to the occurrence of the person approaching or the occurrence of the wake-up word, and a person identification program is executed in the service mode, wherein the person identification program determines a foreground image from at least one candidate image in the real-time image based on a spatial relationship parameter, or extracts a voiceprint from the audio signal, to determine whether the foreground image or the voiceprint corresponds to a resident; A display module and an interactive module, electrically connected to the processing module, the display module, and the mobile unit, are configured to, upon entering the service mode, control the display module to display a resident service interface in response to the processing module detecting the resident, thereby triggering a resident service task through the resident service interface and generating the guidance signal. After displaying the resident service interface, in response to the processing module detecting a change in the identity of the foreground person, the interactive module performs privacy masking processing on sensitive information in the resident service interface. The interactive module is also configured to control the display module to display a standby screen in the standby mode, which includes a virtual guard image.

2. The virtual security device as described in claim 1, wherein, The interactive module is configured to control the display module to display a selection switching service interface when the privacy masking process is performed.

3. The virtual security device as described in claim 1, wherein, The interactive module is configured to, after performing the privacy masking process, respond to the processing module determining within a time limit that the identity of the foreground image has been restored to the resident, remove the privacy masking process and resume the service mode corresponding to the resident.

4. The virtual security device as described in claim 1, wherein, After entering the privacy masking process, if the processing module fails to determine the identity of the foreground person as the resident or the interaction module fails to receive an interaction operation within a certain time limit, the service mode ends and enters the standby mode.

5. The virtual security device as described in claim 1, wherein, The main body further includes a warning module electrically connected to the processing module, which is configured to issue a warning via the warning module based on a warning signal.

6. The virtual security device as described in claim 5, wherein, The virtual security device enters a cruise mode according to the schedule, and the interactive module is configured to generate the guidance signal in the cruise mode to drive the mobile unit to move along a cruise path.

7. The virtual security device as described in claim 6, wherein, The processing module is configured to detect whether the wake word appears in the radio signal in the cruise mode. The cruise mode is suspended and enters the service mode in response to the appearance of the wake word, and the cruise mode is resumed after the service mode ends.

8. The virtual security device as described in claim 6, wherein, The processing module is configured to determine, in the cruise mode, whether the radio signal or the live video contains an abnormal feature corresponding to an abnormal event, and generate the warning signal in response to detecting the abnormal feature.

9. The virtual security device as described in claim 8, wherein, The processing module is configured to generate the guidance signal when it determines that the radio signal contains the abnormal characteristics in the cruise mode, so that the interaction module drives the mobile unit to the location of the abnormal event.

10. The virtual security device as described in claim 6, wherein, The main body further includes a migration detection receiving module electrically connected to the processing module, configured to receive a migration detection signal from a security device. The processing module is configured to generate a warning signal and a guidance signal in response to receiving the migration detection signal and switch to the cruise mode so that the interactive module drives the mobile unit to the location of the security device.

11. The virtual security device as described in claim 5, wherein, The processing module is configured to generate this warning signal in response to the self-detection of a hardware anomaly.

12. The virtual security device as described in claim 1, wherein, The interactive module is configured to, upon entering the service mode, respond to the processing module's determination that there is no corresponding resident, control the display module to display a visitor service interface, thereby triggering a visitor service task through the visitor service interface and generating the guidance signal.

13. The virtual security device as described in claim 12, wherein the interactive module drives the mobile unit to a visitor access area corresponding to the visitor service task or a resident access area corresponding to the resident service task according to the guidance signal.

14. The virtual security device as described in claim 1, wherein, The main body further includes a storage module electrically connected to the processing module, configured to store a resident facial database and a resident voiceprint database for the processing module to identify the resident.
