Description

Safety monitoring device and method and system for implementing safety monitoring

This application claims priority to Chinese Patent Application No. 200610157982.0, entitled "A Videophone and Method and System for Implementing Security Monitoring", filed on December 22, 2006, the entire contents of which are hereby incorporated by reference. The citations are incorporated herein by reference.

Technical field

The present invention relates to communication network technologies, and in particular, to a security monitoring device and a method and system for implementing security monitoring.

Background technique

At present, with the development of video technology, video surveillance is widely used in various fields. As shown in Figure 1, the network diagram used for common cell video surveillance usually installs the camera at intersections, community walls, elevators. In public areas such as walkways, the camera transmits video information to the computer room through the transmission network and presents it to the monitoring personnel through the video wall. The digital switching matrix in the figure is used to select images of different cameras to be displayed on the TV wall. The cost is high and involves the leakage of family privacy, so it is not suitable for monitoring within the family.

As shown in Figure 2, the network diagram used for common home video surveillance, because the balcony is a weak link in home security, users usually set up active infrared sensors on the balcony; before use, users need to submit to the community management office To apply, the management office sets the infrared sensor on the balcony of the user's home to be effective. When the sensor detects that there is a moving object on the balcony, the alarm light corresponding to the home in the management office monitoring room will flash an alarm, indicating that the monitoring personnel may exist. In case of illegal intrusion, the monitoring personnel will take the measures taken; when the user no longer uses such infrared monitoring, it is necessary to request the management to cancel the monitoring. With this scheme, the user needs to apply to the management office to open or stop the monitoring, which increases the expenditure both in time and economically. Moreover, since the infrared sensor cannot distinguish what kind of object is moving, for example, the clothes are blown by the wind. The phenomenon of the alarm will cause the alarm light to flicker, which will generate alarm false alarms, which will bring unnecessary trouble to users and community management personnel.

Summary of the invention

The invention provides a security monitoring device and a method and system for implementing security monitoring, which can not only perform high-reliability security monitoring, but also better protect user privacy.

The invention discloses a security monitoring device, comprising: a camera module for capturing an image or a video; a sensor for generating a detection signal when an object is sensed to be approached; a control module, relating to the sensor And configured to analyze the detection signal when receiving the detection signal from the sensor, and send the image or video captured by the camera module to a preset called object.

The invention also discloses a security monitoring device, comprising: a sensor for detecting a moving object; a camera module, configured to capture an image or video of the moving object when the sensor detects a moving object; When the sensor detects a moving object, the call is made to the called object according to the preset called information, and the image or video of the moving object is sent to the called object.

The invention also discloses a method for implementing security monitoring, capturing an image or video of the moving object when detecting a moving object; making a call to the called object through the preset called information, and moving the moving object An image or video is sent to the called object.

The invention also discloses a system for implementing security monitoring, comprising a security monitoring device with a sensor and a communication network; the security monitoring device is for detecting a moving object, and capturing a captured image or video by using the camera, through the communication network Making a call to a called object, and transmitting the image or video to a called object, performing alarm recovery or making an alarm call to the second called object under the instruction of the called object; the communication network Used to carry the video stream and call control signaling and protocols.

First, the sensor action start time set by the user, that is, the time period of arming and disarming, is obtained from the called information management module 302, and the notification sensor control module 304 is preset. The time start detection function, the stop detection function; when receiving the signal of the detected moving object sent by the sensor control module 304, on the one hand, the camera control module 304 is notified, the movement of the moving object is tracked, the image information or the video stream is captured, and the video is notified. The stream codec/forwarding module 308 encodes the received image information or video stream, and notifies the storage control module 309 to store the encoded image or video stream. On the one hand, the called information management module 302 is queried, and the query is at that time. The called party number of the highest priority of the interval, and automatic dialing; if the dialing is unsuccessful, such as being called busy, etc., and then querying the called user of the second priority of the time period, ... and so on After the called party is connected, the video stream codec/forwarding module 308 is notified to send the captured image or video stream to the called party; after receiving the instruction of the user of the call, the instruction is parsed, and the instruction encapsulation format may be a DTMF code. Or IP format; if it is a secondary call, query the called information management module 302, obtain the called information of the second dialing, make a second call, and alarm to the management office until the second call of the call controller is received. The called user has hanged up the signal, the call management module 303 instructs the camera control module 306 to stop capturing the moving object, the video stream codec/forwarding module 308 stops forwarding and codec, and the storage control module 309 stops the associated storage action; After the called user of one call indicates the indication of alarm recovery, hang up, and notify each relevant module to stop the action;

The sensor control module 304 receives the start and stop detection signals sent by the call management module 303; sends the detection signal of the sensor to the call management module; notifies the call management module 303 when the mobile object is detected, or when the mobile object is no longer in the monitoring area Notify the call management module;

The sensor 305, which may be a microwave sensor or an infrared sensor, is mainly used for sensing a moving object intruding into the room, and transmitting the generated signal to the sensor control module 304;

The camera control module 306 starts or stops tracking and capturing an image or video stream of the moving object under the control of the call management module 303, and sends the captured image or video stream information to the video codec/forwarding module 308 for encoding and forwarding;

a camera 307, configured to capture an image or a video stream, and send the captured image or video stream information to the camera control module;

The video stream codec/forwarding module 308, under the control of the call management module 303, starts the codec function, encodes and decodes the image or video stream from the camera control module 306, and forwards it to the called user and the storage control module 309 or Stop forwarding image or video stream information;

The storage control module 309, under the control of the call management module 303, forwards the image or video stream information from the video stream codec/forward module 308 to the internal or external memory.

The following describes the implementation of the system of the present invention:

Please refer to FIG. 4, which is a networking diagram of the system of the present invention. The various parts in the figure are as follows:

a videophone, for detecting a moving object after the sensor thereon, starting the camera to take a moving object, saving the captured image or video stream to the memory, and simultaneously calling the called object, Then, performing alarm recovery or making an alarm call to the second called object under the instruction of the called object once;

A communication network mainly refers to a carrier that carries video and audio streams and call control signaling and protocols, and may be a data network such as a fixed network, a mobile network, or an IP, or a mixture of various networks;

Call controller, which can receive the calling call and route the call to the correct called object. In practice, it can be a fixed softswitch, a mobile softswitch, an IMS, a program-controlled switch or other call server; The medium call controller is an optional device, because many P2P applications can now be directly called between the primary and the called;

The user is the called user who makes the first call by the videophone. The terminal used by the user can be a videophone or other broadband information terminal, or a mobile communication device such as a mobile phone, or a built-in PC that calls the client, such as Microsoft's NETMEETING, etc.;

The cell management office is a called party that makes a second call by the videophone. Of course, in another specific embodiment of the embodiment of the present invention, it may also be an entity that can handle alarm transactions, such as a security company.

A typical alarm embodiment of the present invention is described below, see Figure 5:

Step 501, the sensor detects the moving object, turns on the camera and performs local storage, and proceeds to step 502;

Step 502: Automatically dial a preset called number for one-time dialing for alarm; there are multiple called numbers generally used for alarms, arranged according to priority, first dialed the highest priority number, if the call is from the call The controller returns cannot be turned on, and then dials the priority number, and then goes down. If all the called parties cannot be connected, go to step 510 (that is, directly dial the number of the second call, which is equivalent to skipping the dialing) ;

Step 503: The call controller receives the call of the videophone and finds the network where the called terminal is located, such as a mobile network user or a fixed network user, etc., to route the call; if the call is unsuccessful, return to step 502;

Step 504: When the call controller finds the called party and the location, the caller is instructed to ring to remind the user to turn on;

Step 505: The user receives the call and picks up the phone;

Step 506: After the called party picks up the phone, the videophone sends the captured image or video to the called party, and the process does not require the call controller to participate; Step 507, after receiving the image or video information, the called user determines whether it is an illegal intrusion, and if so, proceeds to step 508, if not, for example, the small pet of the family is running, then proceeds to step 518;

Step 508: The called user instructs the videophone to perform secondary dialing, for example, the user directly dials "111"; Step 509, the called user hangs up;

Step 510: The videophone automatically dials the called party of the second dialing, for example, the security center of the cell management office; Step 511, the call controller finds the called party and routes the call, and the two steps of 510 and 511 can be combined to realize dialing multiple called Function to enhance the reliability of the alarm;

Step 512: Instruct the called party to ring;

Step 513: The person in charge of the cell management office receives the alarm and processes the alarm.

Step 514: The cell management office hangs up;

Step 515: The on-hook signal of the cell management office is reported to the call controller.

Step 516: After receiving the on-hook signal of the cell management office, the call controller instructs the videophone to hang up; Step 517, the videophone performs alarm recovery (ie, returns to the state before the alarm), and performs actions such as turning off the camera and stopping the storage; End this process.

Step 518: The user instructs the videophone to perform alarm recovery, because the detected moving object is not an abnormal intruder;

Step 519, the called party hangs up;

Step 520: The called user phone reports the on-hook signal to the call controller.

Step 521: The call controller instructs the videophone to resume the alarm.

Step 522: The videophone resumes the alarm, and the same step 517; end the process.

The above is the general process. In actual use, the call control protocol may be SIP, H.323, MGCP, H.248, etc. In general, the call controller can support multiple protocols at the same time, and the terminal supports one of them.

The interaction of the videophone with the called terminal can also interact directly between the two without going through the call controller.

Please refer to FIG. 6. The flow of the call management module in the present invention is as follows:

601. Query the called information management module, and obtain a monitoring time period set by the user; if the user does not set, repeat step 601; 602. Determine whether it is in the monitoring time period; not in the monitoring time period, return to step 601;

603. During the monitoring period, notify the sensor control module to start;

604. Detect the information reported by the sensor control module, determine whether the sensor control module reports a moving object, and if yes, go to step 605; if the sensor control module reports that there is no moving object, return to step 601;

605. The sensor control module reports a moving object, notifies the camera control module, the video stream encoding/decoding module, and the storage control module are started;

606. Query a list of dialed called users of the called information management module, and determine whether it is at the end of the preset one-time dialed called number list, which is the end of the list, that is, no available called number is reached, and step 611 is performed; At the end of the called number list, select the high priority number to make the call;

608. Determine whether the call is successful. If the call is unsuccessful, return to step 607 to select the called number of the second highest priority;

609. The call succeeds, and the video stream codec/forwarding module is notified to the called party to forward the image or the video stream 610, and receives the instruction sent by the called user. If the videophone is instructed to make a second call, the process proceeds to step 611. If the alarm is restored, go to 613.

611. Query the called information management module, obtain the called number of the second dialing, and make a call;

612. The called party waiting for the second dialing hangs up;

613. The camera control module is notified, the video stream codec/forwarding module and the storage control module are stopped, and the alarm is restored, and the process proceeds to step 601.
