Detailed ways

The specific implementation manners of a security alarm system, a home gateway and a security alarm method provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

With the rapid development of computer technology and communication technology, home gateways provided by major broadband operators have gradually entered thousands of households. The security alarm system provided by the embodiment of the present invention is just the existing widely used home gateway. On the basis of functions, it provides users with a low-cost, easy-to-use, safe and reliable security alarm system.

The security alarm system provided by the embodiment of the present invention, as shown in FIG. 1 , includes: at least one infrared sensor 101 and a home gateway 102; wherein:

The infrared sensor 101 is used to detect infrared rays in the monitored area, judge whether an alarm needs to be triggered according to the detection result, and send an alarm signal to the home gateway 102 when an alarm needs to be triggered;

The home gateway 102 is configured to issue a corresponding alarm according to the alarm signal sent by the infrared sensor 101 and a preset alarm policy.

In the embodiment of the present invention, combined with the existing use scenarios of the home gateway and the need for comprehensive security protection, multiple security protection areas can be set in the home, such as the door, window and balcony area of the house, and each monitored An infrared sensor is set in the area, and each infrared sensor communicates with the home gateway. Once an abnormal situation occurs, the infrared sensor sends an alarm message to the home gateway, and the home gateway sends a corresponding alarm.

Specifically, each infrared sensor 101, as shown in FIG. 2 , specifically includes: an infrared transmitter 1011 and an infrared receiver 1012, wherein:

Infrared transmitter 1011, used to transmit modulated multi-beam infrared rays to infrared receiver 1012 in the corresponding monitored area;

The infrared receiver 1012 is used to receive the infrared rays emitted by the infrared transmitter, and send an alarm signal to the home gateway 102 when the number of actually received infrared beams is less than the number of infrared beams emitted by the infrared transmitter 1011 .

In practical applications, for example, the infrared emitter 1011 emits two or four modulated beams of infrared rays, and there is a small distance between each beam of infrared rays. If an object passes through the monitored area, if it is a larger person or object, then the infrared rays emitted by the infrared transmitter 1011 will be completely or mostly blocked and cut off. If a small object such as a household pet passes through the monitored area, it may only block a small part of the infrared rays such as an infrared ray. The infrared receiver 1012 can According to the number of beams of infrared rays actually received, the signal state of itself is set. If the infrared rays emitted by the aforementioned infrared transmitter 1011 are blocked and cut off, the infrared receiver 1012 judges that the number of beams of infrared rays actually received is less than that of the infrared transmitter. 1011 Sending the current signal state as an alarm signal to the home gateway 102 when the number of infrared beams emitted is counted.

For example, if the infrared emitter 1011 emits two beams of infrared rays, the infrared receiver 1012 sets the signal state according to the number of infrared beams actually received as follows:

In the first case, the infrared receiver 1012 normally receives two beams of infrared rays, and its signal state is signal 1;

In the second case, the infrared receiver 1012 receives a beam of infrared rays, and its signal state is signal 2;

In the third case, the infrared receiver 1012 receives 0 beams of infrared rays, and its signal state is signal 3 .

In the second and third cases, the infrared receiver 1012 sends Signal 2 and Signal 3 to the residential gateway 102 .

The home gateway 102, as shown in FIG. 3 , includes: an infrared processor 1021 and an alarm module 1022;

The infrared processor 1021 is configured to receive the signal status sent by the infrared receiver 1012, determine the priority of the alarm, and notify the alarm module 1022 to perform an alarm corresponding to the priority according to the preset alarm strategy;

The alarm module 1022 is configured to issue a corresponding alarm according to the notification from the infrared processor 1021 .

The infrared processor 1021 receives the signal status sent by the infrared receiver 1012 in the infrared sensor 101, and performs corresponding processing according to a preset alarm strategy, which can be set by the user through the WEB page or ITMS.

Wherein the alarm module 1022 can further include: voice transmission based on IP (Voice over IP, VOIP) module 10221, camera control module 10222 and storage module 10223; Wherein:

Specifically, the infrared processor 1021 can determine the priority of the alarm according to the signal status sent by the infrared receiver; setting the strategy includes: when it is determined to be an alarm with a low priority, notify the VOIP module 10221 and the camera control module 10222, when When it is determined as an alarm with high priority, notify the VOIP module 10221, the camera control module 10222 and the storage module 10223;

VOIP module 10221, is used for when infrared processor 1021 is notified as the alarm of low priority, sends alarm message to preset user terminal; And the picture information that camera control module 10222 shoots is sent to user terminal; When infrared processor 10223 When the notification is a high-priority alarm, initiate voice dialing to the preset user terminal within the set time, and transmit the real-time video signal stream captured by the camera control module 10222 to the user terminal;

The camera control module 10222 is used to take a picture of the monitored area and send it to the VOIP module 10221 when the notification is a low-priority alarm; when the notification is a high-priority alarm, record the real-time video of the monitored area and send The recorded real-time video signal stream is transmitted to the VOIP module 10221;

The storage module 10223 is used for storing the real-time video recorded by the camera control module 10222.

Still taking the aforementioned scene where the infrared emitter 1011 emits two beams of infrared rays as an example, when the infrared processor 1021 of the home gateway receives the alarm signal is signal 2 (for example, a household pet passes through the monitored area), the infrared processor 1021 determines as Alarms with low priority will notify the VOIP module 10221 and the camera control module 10222 at the same time. The VOIP module 10221 sends an alarm message to a preset user terminal such as a mobile phone terminal, and the format and content of the alarm message also need to be preset. At the same time, the camera control module 10222 will take a picture of the currently monitored area, and send it to the VOIP module 10221, and send it to the preset user terminal through the VOIP module 10221.

When the alarm signal received by the infrared processor 1021 is signal 3, that is, when all infrared beams are blocked, the infrared processor 1021 determines that it is a high-priority alarm, and the VOIP module 10221 will send an alarm within the preset alarm time. , continue to dial the preset user terminal (multiple terminals of various types can be set at the same time, such as including mobile phones, fixed phones, etc.), until the user connects and confirms. At the same time, the camera control module 10222 also starts recording the real-time video of the monitored area, and sends it to the preset user terminal through the VOIP module 10221, and the storage module 10223 of the home gateway stores the captured real-time video at the same time.

After receiving the captured pictures or videos through the user terminal, the user can use the remote monitoring function of the home gateway through the PC terminal or mobile terminal to remotely control the camera, check the actual situation of the monitored area, and call out the home gateway when necessary. The videos stored in the storage module 10223 are verified.
