The alarm sensor can be a smoke alarm, a water immersion sensor, an acousto-optic sensor and the like, and when corresponding alarm events such as smoke, water immersion, sound, light and the like are detected, an alarm is sent to the alarm gateway based on wireless protocols such as RF433/WIFI/Zigbee and the like.
2) The alarm gateway is used for receiving an alarm sent by the alarm sensor, uploading corresponding alarm information to the cloud service platform according to the alarm, and sending early warning data packets to other alarm gateways around in the ways of RF433/WIFI/Zigbee and the like.
In order to prevent hackers from attacking and cracking the early warning data packet and attacking the early warning network, encryption keys can be negotiated among the alarm gateways in advance, and the early warning data packet is encrypted by the encryption keys and then sent.
In addition, the alarm gateway can also be used for receiving early warning information pushed by the cloud service platform and controlling the state of the alarm sensor. The alarm gateway can be various current intelligent gateway devices supporting RF433/WIFI/Zigbee and other wireless protocols.
3) The cloud service platform is used for receiving alarm information from the alarm gateway, and generating early warning information according to the alarm information and pushing the early warning information to other alarm gateways around the alarm position through a network.
The cloud service platform may be various cloud servers. After receiving the alarm information from the alarm gateway, the cloud service platform can also push the alarm information to the APP of the terminal of the relevant user through the network.
In the invention, when an alarm occurs, the alarm gateway broadcasts the early warning data packet to other alarm gateways around by adopting wireless modes such as RF433/WIFI/Zigbee and the like, and the signal attenuation characteristic of the wireless broadcast packet is utilized to ensure that the alarm gateway which can receive the early warning data packet is basically controlled within 100 meters of a square circle, thereby realizing targeted early warning for users around the alarm. In addition, in order to enhance the reliability of early warning, the cloud service platform also sends early warning information to the alarm gateways around the position based on the position where the alarm occurs, so that the alarm gateways receiving the early warning data packet and the early warning information can combine the two information to further confirm the reliability of the alarm information.
Based on the system shown in fig. 1, the invention provides an intelligent home early warning method, which is applied to an alarm gateway and comprises the following steps:
the alarm gateway receives an alarm from the alarm sensor, uploads corresponding alarm information to the cloud service platform according to the alarm, and broadcasts an early warning data packet to other alarm gateways around in a wireless mode;
and after the alarm information is received by the cloud service platform, the cloud service platform generates early warning information and pushes the early warning information to other alarm gateways around the alarm position.
Preferably, the alarm gateway uploads the ID of the alarm gateway and the position set by the user to the cloud service platform;
the alarm information comprises the ID of the alarm gateway, and the ID of the alarm gateway is used for confirming the position of the corresponding user by the cloud service platform so as to push early warning information to other alarm gateways around the position.
Preferably, the alarm gateway broadcasts the encrypted early warning data packet to other alarm gateways around through an RF433/WIFI/Zigbee wireless protocol, wherein the encryption key is a key negotiated in advance between the alarm gateways.
Preferably, the method may further include: the warning gateway receives warning data packets broadcasted by surrounding warning gateways, receives warning information pushed by a cloud service platform, combines the warning data packets with the warning information, confirms that danger exists around the warning gateway, and sends danger prompts to users corresponding to the warning gateway.
In practical application, when a user needs to use the alarm gateway, the position of the user is preset through an APP on a terminal (if the position is not set, the default IP address for logging in by using the alarm gateway is confirmed), and the ID (product ID) of the user and the position set by the user are uploaded to a cloud service platform by the alarm gateway. When a fire disaster in a user home is detected by the smoke sensor, the alarm gateway of the user receives an alarm sent by the smoke sensor, reports alarm information (specifically, a fire alarm event) to the cloud service platform, and informs the owner of the alarm. Meanwhile, the alarm gateway sends encrypted early warning data packets to the surroundings in a wireless mode such as WIFI and RF433, and due to the fact that the transmission capability of wireless equipment such as WIFI and RF433 is limited, the early warning data packets can be received only by other alarm gateways which are close to each other (basically within 100 meters of a square circle). Meanwhile, after receiving the alarm information, the cloud service platform searches the corresponding position information of the user through the ID of the alarm gateway and issues early warning information to the alarm gateways around the user. And the surrounding alarm gateways combine the early warning data packet received from the alarm gateway of the user and the early warning information issued by the cloud service platform to confirm that the surrounding danger exists, and immediately send out an alarm to the corresponding users to remind the users of withdrawing.
The flow of the smart home warning system performing the warning in the embodiment of the present invention is shown in fig. 2, which illustrates the following:
s100, when a user uses the alarm gateway (also called a gateway host, an alarm host and the like) for the first time, the APP is used for adding the alarm sensor, and then the APP reminds the user to set the position information of the alarm gateway (if the user is not set, the network IP address is used by default to confirm the basic position information). And after the alarm gateway is connected with the network, the product ID and the position information are reported to the cloud service platform.
S101, when a fire disaster occurs in a user home, the fire disaster is reported to an alarm gateway after being detected by a smoke sensor, the alarm gateway immediately sends an alarm, meanwhile, on-site alarm information is reported to a cloud service platform, and an encrypted early warning data packet is sent in a WIFI/RF433/ZigBee mode and the like.
S102, after receiving the alarm information, the cloud platform confirms the specific position of the alarm gateway through the product ID of the alarm gateway, searches the alarm gateways around the position, and pushes the early warning information to the alarm gateways around the position. Meanwhile, the APP of the terminal of the user corresponding to the alarm is pushed to alarm information through the network.
And S103, the alarm gateways around the fire position receive the surrounding data packets, decrypt the data packets and confirm the data packets as early warning data packets.
And S104, the alarm gateways around the fire position confirm that danger exists around according to the early warning information pushed by the cloud service platform and the received wireless early warning data packet.
And S105, after confirming the danger, the alarm gateways around the fire position respectively send out an alarm to remind corresponding users to pay attention to the surrounding danger.
Based on the technical scheme provided by the invention, the method can be further refined, and the cooperative processing of the alarm system and the cloud service is provided for different systems and scenes, for example, after an accident occurs in a cell or a public place, a sensor on a user receives a wireless early warning data packet, and the early warning information received by a mobile phone APP is combined to confirm that a danger exists around the user.
The processing executed by the alarm gateway of the present invention is shown in fig. 3, and includes:
when an alarm occurs around, receiving an encrypted wireless early warning data packet from a surrounding alarm gateway, and receiving corresponding early warning information from a cloud service platform; then, confirming surrounding danger by combining the wireless early warning data packet and early warning information pushed by the cloud service platform, and sending an alarm signal indicating that the surrounding danger exists to a user;
